Now that conf/options knows about if_iwn.h, add it to if_iwn.c. This allows for IWN_DEBUG (and maybe more stuff later) to be a build time configure option.

net80211 rate control framework (net80211 ratectl). This framework allows drivers to abstract the rate control algorithm and just feed the framework with the usable parameters. The rate control framework will now deal with passing the parameters to the selected algorithm. Right now we have AMRR (the default) and RSSADAPT but there's no way to select one with ifconfig, yet. The objective is to have more rate control algorithms in the net80211 stack so all drivers[0] can use it. Ideally, we'll have the well-known sample rate control algorithm in the net80211 at some point so all drivers can use it (not just ath). [0] all drivers that do rate control in software, that is.

Inform the rate control code if a single frame AMPDU transmission succeeds but has some retries. Without this, single frame transmission in AMPDU will always look like it succeeded fine, and thus AMRR will think it's totally fine to just keep upping the rate upwards. Now, this is still not quite right! For multi-frame aggregates the completion happens in two parts - the TX done and the BA received. The driver is currently double accounting those a little - there's no way to say to the rate control code "I completed X frames, Y worked fine, there were Z retries." And it's a bit odd with iwn, as the firmware retransmits frames for us so we don't get to see how many retransmits happened; only that it took longer than normal. I may have to extend the rate control API to properly track that. So this may keep the rate lower than it should be, but that's better than keeping it higher than it should be. Tested: * 5100, STA mode

Begin fleshing out some code to handle tracking PLCP error rates in preparation for the scan based retune logic. The linux iwlwifi driver does a rescan (onto a non-active channel) to force an RF retune when the PLCP error rates exceed a certain threshold. * Add code to track HT PLCP rate errors; * Separate out the PLCP error count fetch and update so the delta can be used when checking for PLCP error rates; * Implement the PLCP error logic from iwlwifi; * For now, just print out whenever the error rate exceeds the threshold. The actual scan based retune will take a bit more effort; the scan command code right now assumes that a scan state is passed in. This does need to change to be more flexible (both for this and in preparation for scanning multiple channels at once.) Tested: * 5100 (STA mode) * 2200 (STA mode) * 2230 (STA mode)

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

The firmware of 4965 series adapters seems to die while trying to send probe requests at 1Mbps while being associated on a 5GHz channel. Sending those at 6Mbps does work, so use that instead during a background scan. This workaround allows us to re-enable background scan support for the 4965 adapters. Also, just enabling one antenna on 5GHz results in better reception of beacons: test 00:26:5a:c6:14:1a 40 54M -71:-95 200 E WME HTCAP ATH vs test 00:26:5a:c6:14:1a 40 54M -92:-95 200 E WME HTCAP ATH Due to roam:rssi thresholds set to 7 by default it might have been impossible to associate to that network. While here use IEEE80211_IS_CHAN_5GHZ() to determine the band.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out.

Add new tunable 'net.link.ifqmaxlen' to set default send interface queue length. The default value for this parameter is 50, which is quite low for many of today's uses and the only way to modify this parameter right now is to edit if_var.h file. Also add read-only sysctl with the same name, so that it's possible to retrieve the current value. MFC after: 1 month

Handle the newer-style bluetooth message format from the (at least) Centrino 2230 firmware. This fixes the general statistics block to be actually valid. I've verified this by contrasting the output of iwnstats before and after the change. The general block is now correct.

Commit over some work to prepare the iwn(4) driver for further chipset support. * Extend the hardware base_params structure to include a bunch of hardware flags indicating what is and isn't supported. * Convert a bunch of the initial hardware configuration conditionals to consult the base_params structure. * Add new calibration code for temperature calibration for the Centrino 2xxx series NICs. * Add new bluetooth coexistence code for Centrino 2xxx series NICs. * For NICs that support PAN (personal area networking), use a different transmit queue and command queue setup, in preparation for said PAN support. * Extend the calibration array in iwn_softc to include enough space for the new calibration types. Tested (by myself, if not mentioned): * Intel 4965 * Intel 5100 * Intel 6150 * Intel 2230 * Intel 2200 (eadler) * Intel 1030 * Intel 6200 * Intel 6230 * Intel 6250 * Intel 6150 * Intel 100 What doesn't work: * Intel 6235 - fails in calibration at startup TODO: * Testing on Intel 53xx series hardware Submitted by: Cedric Gross <cg@cgross.info>

net80211 rate control framework (net80211 ratectl). This framework allows drivers to abstract the rate control algorithm and just feed the framework with the usable parameters. The rate control framework will now deal with passing the parameters to the selected algorithm. Right now we have AMRR (the default) and RSSADAPT but there's no way to select one with ifconfig, yet. The objective is to have more rate control algorithms in the net80211 stack so all drivers[0] can use it. Ideally, we'll have the well-known sample rate control algorithm in the net80211 at some point so all drivers can use it (not just ath). [0] all drivers that do rate control in software, that is.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

/* Set antenna configuration */
Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out.

Updates to the iwn driver: * iwnfw has now been split into individual modules so autoloading of firmware module(s) does work again. * Changes have been made to RUN -> AUTH transition, this should fix the issue reported by Glen and others. * Brandon reported issues in iwn_cmd() with large commands, those have been fixed to. * DEAUTH is now handled correctly.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested.

Inform the rate control code if a single frame AMPDU transmission succeeds but has some retries. Without this, single frame transmission in AMPDU will always look like it succeeded fine, and thus AMRR will think it's totally fine to just keep upping the rate upwards. Now, this is still not quite right! For multi-frame aggregates the completion happens in two parts - the TX done and the BA received. The driver is currently double accounting those a little - there's no way to say to the rate control code "I completed X frames, Y worked fine, there were Z retries." And it's a bit odd with iwn, as the firmware retransmits frames for us so we don't get to see how many retransmits happened; only that it took longer than normal. I may have to extend the rate control API to properly track that. So this may keep the rate lower than it should be, but that's better than keeping it higher than it should be.

Inform the rate control code if a single frame AMPDU transmission succeeds but has some retries. Without this, single frame transmission in AMPDU will always look like it succeeded fine, and thus AMRR will think it's totally fine to just keep upping the rate upwards. Now, this is still not quite right! For multi-frame aggregates the completion happens in two parts - the TX done and the BA received. The driver is currently double accounting those a little - there's no way to say to the rate control code "I completed X frames, Y worked fine, there were Z retries." And it's a bit odd with iwn, as the firmware retransmits frames for us so we don't get to see how many retransmits happened; only that it took longer than normal. I may have to extend the rate control API to properly track that. So this may keep the rate lower than it should be, but that's better than keeping it higher than it should be.

If A-MPDU transmission fails entirely, then no BA is received from the NIC and pushed up to the driver. Unfortunately this means there's no rate control notification done. Thus, if the rate control code makes a decision that hits a crappy rate that can't succeed, the rate code would never lower the rate and packet loss would continue. So, fake some rate control notification in this case.

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

Create a taskqueue for each wireless interface which provides a serialised sleepable context for net80211 driver callbacks. This removes the need for USB and firmware based drivers to roll their own code to defer the chip programming for state changes, scan requests, channel changes and mcast/promisc updates. When a driver callback completes the hardware state is now guaranteed to have been updated and is in sync with net80211 layer. This nukes around 1300 lines of code from the wireless device drivers making them more readable and less race prone. The net80211 layer has been updated as follows - all state/channel changes are serialised on the taskqueue. - ieee80211_new_state() always queues and can now be called from any context - scanning runs from a single taskq function and executes to completion. driver callbacks are synchronous so the channel, phy mode and rx filters are guaranteed to be set in hardware before probe request frames are transmitted.

Fix up the link quality lookup and re-enable multi-rate retry. This is a terrible solution that at least behaves mostly correctly. It walks the currently active rate table looking for rates to match. It assumes that the code matches the setup path in the link quality setup code (much like the previous, much simpler but even more hackish math did.) It's O(n), but n<15, so we're okay for the time being. Tested: * Intel 5100, STA - 11a, 11n, 11bg modes.

Fix up the link quality lookup and re-enable multi-rate retry. This is a terrible solution that at least behaves mostly correctly. It walks the currently active rate table looking for rates to match. It assumes that the code matches the setup path in the link quality setup code (much like the previous, much simpler but even more hackish math did.) It's O(n), but n<15, so we're okay for the time being. Tested: * Intel 5100, STA - 11a, 11n, 11bg modes.

So, until I or someone else decides to fix it, let's just disable it for now. * Teach iwn_tx_data_raw() to use the iwn_rate_to_plcp() function. * Eliminate two uses of the net80211 rate index lookup functions - they are only for legacy rates and they're not needed here. This fixes some invalid looking rate control TX issues that showed up on my 4965 but it doesn't fix the two TX hangs I've noticed. Those look like DMA related issues.

Implement basic 802.11n awareness in the PHY and AMRR rate control code. * Add 802.11n 2ghz and 5ghz tables, including legacy rates and up to MCS23 rates (3x3.) * Populate the rate code -> rate index lookup table with MCS _and_ normal rates, but _not_ the basic rate flag. Since the basic rate flag is the same as the MCS flag, we can only use one. * Introduce some accessor inlines that do PLCP and rate table lookup/access and enforce that it doesn't set the basic rate bit. They're not designed for MCS rates, so it will panic. * Start converting drivers that use the rate table stuff to use the accessor inlines and strip the basic flag. * Teach AMRR about basic 11n - it's still as crap for MCS as it is being used by iwn, so it's not a step _backwardS_. * Convert iwn over to accept 11n MCS rates rather than 'translate' legacy to MCS rates. It doesn't use a lookup table any longer; instead it's a function which takes the current node (for HT parameters) and the rate code, and returns the hardware PLCP code to use. Tested: * ath - it's a no-op, and it works that way * iwn - both 11n and non-11n

DPRINTF(sc, IWN_DEBUG_XMIT,
Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

flags,
Commit over some work to prepare the iwn(4) driver for further chipset support. * Extend the hardware base_params structure to include a bunch of hardware flags indicating what is and isn't supported. * Convert a bunch of the initial hardware configuration conditionals to consult the base_params structure. * Add new calibration code for temperature calibration for the Centrino 2xxx series NICs. * Add new bluetooth coexistence code for Centrino 2xxx series NICs. * For NICs that support PAN (personal area networking), use a different transmit queue and command queue setup, in preparation for said PAN support. * Extend the calibration array in iwn_softc to include enough space for the new calibration types. Tested (by myself, if not mentioned): * Intel 4965 * Intel 5100 * Intel 6150 * Intel 2230 * Intel 2200 (eadler) * Intel 1030 * Intel 6200 * Intel 6230 * Intel 6250 * Intel 6150 * Intel 100 What doesn't work: * Intel 6235 - fails in calibration at startup TODO: * Testing on Intel 53xx series hardware Submitted by: Cedric Gross <cg@cgross.info>

Temporarily disable multi-rate retry (link quality) and eliminate rate index lookups. * My recent(ish) change to iwn(4) and the net80211 rate control API to support 11n rates broke the link quality table use. So, until I or someone else decides to fix it, let's just disable it for now. * Teach iwn_tx_data_raw() to use the iwn_rate_to_plcp() function. * Eliminate two uses of the net80211 rate index lookup functions - they are only for legacy rates and they're not needed here. This fixes some invalid looking rate control TX issues that showed up on my 4965 but it doesn't fix the two TX hangs I've noticed. Those look like DMA related issues. Tested: * 4965, STA mode * 5100, STA mode

Since the basic rate flag is the same as the MCS flag, we can only use one. * Introduce some accessor inlines that do PLCP and rate table lookup/access and enforce that it doesn't set the basic rate bit. They're not designed for MCS rates, so it will panic. * Start converting drivers that use the rate table stuff to use the accessor inlines and strip the basic flag. * Teach AMRR about basic 11n - it's still as crap for MCS as it is being used by iwn, so it's not a step _backwardS_. * Convert iwn over to accept 11n MCS rates rather than 'translate' legacy to MCS rates. It doesn't use a lookup table any longer; instead it's a function which takes the current node (for HT parameters) and the rate code, and returns the hardware PLCP code to use.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly!

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

Revert iwn channel-argument handling of set_txpower() to r201822 Pass the channel argument as a real argument and not through RXON. The RXON version seems to have problem with both the older 228.57.2.23 firmware and the latest 228.61.2.24 version resulting in device initialization errors like: wpa_supplicant[2928]: Failed to initiate AP scan. kernel: firmware error log: kernel: error type = "SYSASSERT" (0x00000005) kernel: program counter = 0x0000147C kernel: source line = 0x0000058B kernel: error data = 0x0000058B00000000 kernel: branch link = 0x0000145A00001492 kernel: interrupt link = 0x000006DE00000000 kernel: time = 7310 ... kernel: iwn0: iwn_config: could not set TX power kernel: iwn0: iwn_init_locked: could not configure device, error 35 By passing the current channel to hal->set_txpower() the firmware error is fixed, at least for the 4965 chipset of my Thinkpad and the ones tested by Bernhard.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

Pull some features out of the firmware: - If a ENH_SENS TLV section exit the firmware is capable of doing enhanced sensitivity calibration. - Newer devices/firmwares have more calibration commands therefore hardcoding the noise gain/reset commands no longer works. It is supposed to use the next index after the newest calibration type support. Read the command index of the TLV section if available.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Begin fleshing out some code to handle tracking PLCP error rates in preparation for the scan based retune logic. The linux iwlwifi driver does a rescan (onto a non-active channel) to force an RF retune when the PLCP error rates exceed a certain threshold. * Add code to track HT PLCP rate errors; * Separate out the PLCP error count fetch and update so the delta can be used when checking for PLCP error rates; * Implement the PLCP error logic from iwlwifi; * For now, just print out whenever the error rate exceeds the threshold. The actual scan based retune will take a bit more effort; the scan command code right now assumes that a scan state is passed in. This does need to change to be more flexible (both for this and in preparation for scanning multiple channels at once.) Tested: * 5100 (STA mode) * 2200 (STA mode) * 2230 (STA mode)

Implement basic 802.11n awareness in the PHY and AMRR rate control code. * Add 802.11n 2ghz and 5ghz tables, including legacy rates and up to MCS23 rates (3x3.) * Populate the rate code -> rate index lookup table with MCS _and_ normal rates, but _not_ the basic rate flag. Since the basic rate flag is the same as the MCS flag, we can only use one. * Introduce some accessor inlines that do PLCP and rate table lookup/access and enforce that it doesn't set the basic rate bit. They're not designed for MCS rates, so it will panic. * Start converting drivers that use the rate table stuff to use the accessor inlines and strip the basic flag. * Teach AMRR about basic 11n - it's still as crap for MCS as it is being used by iwn, so it's not a step _backwardS_. * Convert iwn over to accept 11n MCS rates rather than 'translate' legacy to MCS rates. It doesn't use a lookup table any longer; instead it's a function which takes the current node (for HT parameters) and the rate code, and returns the hardware PLCP code to use. Tested: * ath - it's a no-op, and it works that way * iwn - both 11n and non-11n

/* Configure valid TX chains for >=5000 Series. */
Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly!

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly!

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

Make the scan state optional - we'll obviously need a vap, but we now won't require the scan state. the only thing the scan state is needed for is to check for the list of SSIDs to scan - which we can now just plain ignore by passing in NULL as the scan state pointer.

Prepare for transmitting frames at MCS rates: - instead of calling iwn_plcp_signal() for every frame, map the expected value directly within wn->ridx - concat plcp, rflags and xrflags, there is no clean byte boundary within the flags, for example the antenna setting uses bit 6, 7 and 8 - there is still need for a custom rate to plcp mapping, as those expected by the hardware are not conform to the std

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

Create a taskqueue for each wireless interface which provides a serialised sleepable context for net80211 driver callbacks. This removes the need for USB and firmware based drivers to roll their own code to defer the chip programming for state changes, scan requests, channel changes and mcast/promisc updates. When a driver callback completes the hardware state is now guaranteed to have been updated and is in sync with net80211 layer. This nukes around 1300 lines of code from the wireless device drivers making them more readable and less race prone. The net80211 layer has been updated as follows - all state/channel changes are serialised on the taskqueue. - ieee80211_new_state() always queues and can now be called from any context - scanning runs from a single taskq function and executes to completion. driver callbacks are synchronous so the channel, phy mode and rx filters are guaranteed to be set in hardware before probe request frames are transmitted.

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

Begin fleshing out some code to handle tracking PLCP error rates in preparation for the scan based retune logic. The linux iwlwifi driver does a rescan (onto a non-active channel) to force an RF retune when the PLCP error rates exceed a certain threshold. * Add code to track HT PLCP rate errors; * Separate out the PLCP error count fetch and update so the delta can be used when checking for PLCP error rates; * Implement the PLCP error logic from iwlwifi; * For now, just print out whenever the error rate exceeds the threshold. The actual scan based retune will take a bit more effort; the scan command code right now assumes that a scan state is passed in. This does need to change to be more flexible (both for this and in preparation for scanning multiple channels at once.) Tested: * 5100 (STA mode) * 2200 (STA mode) * 2230 (STA mode)

Begin fleshing out some code to handle tracking PLCP error rates in preparation for the scan based retune logic. The linux iwlwifi driver does a rescan (onto a non-active channel) to force an RF retune when the PLCP error rates exceed a certain threshold. * Add code to track HT PLCP rate errors; * Separate out the PLCP error count fetch and update so the delta can be used when checking for PLCP error rates; * Implement the PLCP error logic from iwlwifi; * For now, just print out whenever the error rate exceeds the threshold. The actual scan based retune will take a bit more effort; the scan command code right now assumes that a scan state is passed in. This does need to change to be more flexible (both for this and in preparation for scanning multiple channels at once.) Tested: * 5100 (STA mode) * 2200 (STA mode) * 2230 (STA mode)

/* Mark TX rings (4 EDCA + cmd + 2 HCCA) as active. */
Commit over some work to prepare the iwn(4) driver for further chipset support. * Extend the hardware base_params structure to include a bunch of hardware flags indicating what is and isn't supported. * Convert a bunch of the initial hardware configuration conditionals to consult the base_params structure. * Add new calibration code for temperature calibration for the Centrino 2xxx series NICs. * Add new bluetooth coexistence code for Centrino 2xxx series NICs. * For NICs that support PAN (personal area networking), use a different transmit queue and command queue setup, in preparation for said PAN support. * Extend the calibration array in iwn_softc to include enough space for the new calibration types. Tested (by myself, if not mentioned): * Intel 4965 * Intel 5100 * Intel 6150 * Intel 2230 * Intel 2200 (eadler) * Intel 1030 * Intel 6200 * Intel 6230 * Intel 6250 * Intel 6150 * Intel 100 What doesn't work: * Intel 6235 - fails in calibration at startup TODO: * Testing on Intel 53xx series hardware Submitted by: Cedric Gross <cg@cgross.info>

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Fix antenna configuration, microcode version checks and rate selection in preparation for the 5300 3x3 NIC. During this particular adventure, I did indeed discover that a whole swath of things made little to no sense. Those included, and are fixed here: * A lot of the antenna configuration bits assume the NIC has two receive chains. That's blatantly untrue for NICs that don't. * There was some disconnect between the antenna configuration when forming a PLCP rate DWORD (which includes the transmit antenna configuration), separate to the link quality antenna configuration. So now there's helper functions to return which antenna configurations to use and those are used wherever an antenna config is required. * The 5300 does up to three stream TX/RX (so MCS0->23), however the link quality table has only 16 slots. This means all of the rate entries are .. well, dual-stream rates. If this is the case, the "last MIMO" parameter can't be 16 or it panics the firmware. Set it to 15. * .. and since yes it has 16 slots, it only would try retransmitting from MCS8->MCS23, which can be quite .. terrible. Hard-code the last two retry slots to be the lowest configured rate. * I noticed some transmit configuration command stuff is different based on firmware API version, so I lifted that code from Linux. * Add / augment some more logging to make it easier to capture this stuff. Now, 3x3 is still terrible because the link quality configuration is plainly not good enough. I'll have to think about that. However, the original goal of this - 3x3 operation on the Intel 5300 NIC - actually worked. There are also rate control bugs in the way this driver handles notifying the net80211 rate control code when AMPDU is enabled. It always steps the rate up to the maximum rate possible - and this eventually ends in much sadness. I'll fix that later. As a side note - 2GHz HT40 now works on all the NICs I have tested. As a second side note - this exposed some bad 3x3 behaviour in the ath(4) rate control code where it starts off at a 3-stream rate and doesn't downgrade quickly enough. This makes the initial dhcp exchange take a long time. I'll fix the ath(4) rate code to start at a low fixed 1x1 MCS rate and step up if everything works out. Tested: * Intel 2200 * Intel 2230 * Intel 5300 * Intel 5100 * Intel 6205 * Intel 100 TODO: * Test the other NICs more thoroughly! Thank you to Michael Kosarev <russiane39@gmail.com> for donating the Intel 5300 NIC and pestering me about it since last year to try and make it all work.

Commit over some work to prepare the iwn(4) driver for further chipset support. * Extend the hardware base_params structure to include a bunch of hardware flags indicating what is and isn't supported. * Convert a bunch of the initial hardware configuration conditionals to consult the base_params structure. * Add new calibration code for temperature calibration for the Centrino 2xxx series NICs. * Add new bluetooth coexistence code for Centrino 2xxx series NICs. * For NICs that support PAN (personal area networking), use a different transmit queue and command queue setup, in preparation for said PAN support. * Extend the calibration array in iwn_softc to include enough space for the new calibration types. Tested (by myself, if not mentioned): * Intel 4965 * Intel 5100 * Intel 6150 * Intel 2230 * Intel 2200 (eadler) * Intel 1030 * Intel 6200 * Intel 6230 * Intel 6250 * Intel 6150 * Intel 100 What doesn't work: * Intel 6235 - fails in calibration at startup TODO: * Testing on Intel 53xx series hardware Submitted by: Cedric Gross <cg@cgross.info>

Overhaul the iwn(4) scan infrastructure to be slightly more "correct" for these chipsets. * Correctly set the active/passive flag in the scan request - this is NOT a "is the channel active|passive"; it's to do with whether we have an SSID to actively scan for or not. The firmware takes care of the active/passive setup of the channel. * Calculate the active/passive dwell time based on the beacon interval and the channel mode, rather than using a hard coded value. * For now, hardcode the scan service_time. It's defined as: 31:22 - number of beacon intervals to come back onto the home channel for; 0:21 - time (microseconds) to come back onto the home channel for. When doing an active scan when the NIC is active (whether we're associated or not - it only matters if we've setup the NIC to a destination or not) this determines how much time to stay on the home channel for when scanning. We can tune this based on the amount of active traffic. For now it's 4 beacon intervals and 100 microseconds. * Fix the "good crc threshold" setting. It differs based on the NIC firmware. Some older firmware required a workaround; the later firmware instead treats the field as a flag. * Enforce that we are not sending a scan command if one is already pending. Any time this is done is a bug and it absolutely needs to be fixed - so be very loud. * Add the SCAN flag to a few debug messages that are scan related but only occuring under STATE. Now, this does get noisy when you're scanning in an actively busy 2GHz network as the firmware (for reason I don't quite yet understand) seems hell bent on staying on some passive channels longer than it should. However, it should eventually recover and complete the scan. This is a work in progress; please let me know if things get stuck or if things improve!

This nukes around 1300 lines of code from the wireless device drivers making them more readable and less race prone. The net80211 layer has been updated as follows - all state/channel changes are serialised on the taskqueue. - ieee80211_new_state() always queues and can now be called from any context - scanning runs from a single taskq function and executes to completion. driver callbacks are synchronous so the channel, phy mode and rx filters are guaranteed to be set in hardware before probe request frames are transmitted.

Make the scan state optional - we'll obviously need a vap, but we now won't require the scan state. the only thing the scan state is needed for is to check for the list of SSIDs to scan - which we can now just plain ignore by passing in NULL as the scan state pointer. Tested: * Intel 5100 (STA)

Create a taskqueue for each wireless interface which provides a serialised sleepable context for net80211 driver callbacks. This removes the need for USB and firmware based drivers to roll their own code to defer the chip programming for state changes, scan requests, channel changes and mcast/promisc updates. When a driver callback completes the hardware state is now guaranteed to have been updated and is in sync with net80211 layer. This nukes around 1300 lines of code from the wireless device drivers making them more readable and less race prone. The net80211 layer has been updated as follows - all state/channel changes are serialised on the taskqueue. - ieee80211_new_state() always queues and can now be called from any context - scanning runs from a single taskq function and executes to completion. driver callbacks are synchronous so the channel, phy mode and rx filters are guaranteed to be set in hardware before probe request frames are transmitted.
