Replace most compile-time support options with linker sets for chip and RF backend support: o add OS_DATA_SET and OS_SET_DECLARE os requirements for setting up linker sets o add AH_CHIP macro for registering chip support (e.g. 5210) o add AH_RF macro for registering RF support (e.g. 2413); note this isn't required for single chip solutions where there's no ambiguity (e.g. 5416/9160+2133) but for 5212 class parts it's required because of the multi-chip solutions o remove all uses of AH_SUPPORT_AR5210, AH_SUPPORT_AR5211, AH_SUPPORT_5212, and AH_SUPPORT_AR9160; still need AH_SUPPORT_AR5416 to enable the 11n descriptor formats and 5312 support is presently broken o remove all uses of AH_SUPPORT_2133, AH_SUPPORT_2413, AH_SUPPORT_5111, AH_SUPPORT_5112, AH_SUPPORT_2417, AH_SUPPORT_2425, and AH_SUPPORT_5413; 5312-related support still requires fixup Remaining issues: o fixup SoC attach o ath_hal_attach uses a hack to probe w/o access to the vendorid o fallback handling of parts w/o a macrev needs to be restored

Add a new HAL method to retrieve the completion schedule. It sets the completion schedule from the hardware and returns AH_TRUE if the hardware supports multi-rate retries (AR5212 and above); and returns AH_FALSE if the hardware doesn't support multi-rate retries. The sample rate module directly reads the TX completion descriptor and extracts the TX schedule information from that. It will be updated in a future commit to instead use this method to determine the completion schedule.

Break out the TX descriptor link field into HAL methods. The DMA FIFO chips (AR93xx and later) differ slightly to th elegacy chips: * The RX DMA descriptors don't have a ds_link field; * The TX DMA descriptors have a ds_link field however at a different offset. This is a reimplementation based on what the reference driver and ath9k does. A subsequent commit will enable it in the TX and beacon paths. Obtained from: Linux ath9k, Qualcomm Atheros

ANI changes #1 - split out the ANI polling from the RxMonitor hook. The rxmonitor hook is called on each received packet. This can get very, very busy as the tx/rx/chanbusy registers are thus read each time a packet is received. Instead, shuffle out the true per-packet processing which is needed and move the rest of the ANI processing into a periodic event which runs every 100ms by default.

Update the TSF and next-TBTT methods to work for the AR5416 and later NICs. This is another commit in a series of TDMA support fixes for the 11n NICs. * Move ath_hal_getnexttbtt() into the HAL; write methods for it. This returns a timer value in TSF, rather than TU. * Move ath_hal_getcca() and ath_hal_setcca() into the HAL too, where they likely now belong. * Create a new HAL capability: HAL_CAP_LONG_RXDESC_TSF. The pre-11n NICs write 15 bit TSF snapshots into the RX descriptor; the AR5416 and later write 32 bit TSF snapshots into the RX descriptor. * Use the new capability to choose between 15 and 31 bit TSF adjustment functions in ath_extend_tsf(). * Write ar5416GetTsf64() and ar5416SetTsf64() methods. ar5416GetTsf64() tries to compensate for TSF changes at the 32 bit boundary. According to yin, this fixes the TDMA beaconing on 11n chipsets and TDMA stations can now associate/talk, but there are still issues with traffic stability which need to be investigated. The ath_hal_extendtsf() function is also used in RX packet timestamping; this may improve adhoc mode on the 11n chipsets. It also will affect the timestamps seen in radiotap frames.

Replace most compile-time support options with linker sets for chip and RF backend support: o add OS_DATA_SET and OS_SET_DECLARE os requirements for setting up linker sets o add AH_CHIP macro for registering chip support (e.g. 5210) o add AH_RF macro for registering RF support (e.g. 2413); note this isn't required for single chip solutions where there's no ambiguity (e.g. 5416/9160+2133) but for 5212 class parts it's required because of the multi-chip solutions o remove all uses of AH_SUPPORT_AR5210, AH_SUPPORT_AR5211, AH_SUPPORT_5212, and AH_SUPPORT_AR9160; still need AH_SUPPORT_AR5416 to enable the 11n descriptor formats and 5312 support is presently broken o remove all uses of AH_SUPPORT_2133, AH_SUPPORT_2413, AH_SUPPORT_5111, AH_SUPPORT_5112, AH_SUPPORT_2417, AH_SUPPORT_2425, and AH_SUPPORT_5413; 5312-related support still requires fixup Remaining issues: o fixup SoC attach o ath_hal_attach uses a hack to probe w/o access to the vendorid o fallback handling of parts w/o a macrev needs to be restored

Include the initial support for external EEPROMs. The AR9100 at least doesn't have an external serial EEPROM attached to the MAC; it instead stores the calibration data in the normal system flash. I believe earlier parts can do something similar but I haven't experienced it first-hand. This commit introduces an eepromdata pointer into the API but doesn't at all commit to using it. A future commit will include the glue needed to allow the AR9100 support code to use this data pointer as the EEPROM.

Overhaul regulatory support: o remove HAL_CHANNEL; convert the hal to use net80211 channels; this mostly involves mechanical changes to variable names and channel attribute macros o gut HAL_CHANNEL_PRIVATE as most of the contents are now redundant with the net80211 channel available o change api for ath_hal_init_channels: no more reglass id's, no more outdoor indication (was a noop), anM contents o add ath_hal_getchannels to have the hal construct a channel list without altering runtime state; this is used to retrieve the calibration list for the device in ath_getradiocaps o add ath_hal_set_channels to take a channel list and regulatory data from above and construct internal state to match (maps frequencies for 900MHz cards, setup for CTL lookups, etc) o compact the private channel table: we keep one private channel per frequency instead of one per HAL_CHANNEL; this gives a big space savings and potentially improves ani and calibration by sharing state (to be seen; didn't see anything in testing); a new config option AH_MAXCHAN controls the table size (default to 96 which was chosen to be ~3x the largest expected size) o shrink ani state and change to mirror private channel table (one entry per frequency indexed by ic_devdata) o move ani state flags to private channel state o remove country codes; use net80211 definitions instead o remove GSM regulatory support; it's no longer needed now that we pass in channel lists from above o consolidate ADHOC_NO_11A attribute with DISALLOW_ADHOC_11A o simplify initial channel list construction based on the EEPROM contents; we preserve country code support for now but may want to just fallback to a WWR sku and dispatch the discovered country code up to user space so the channel list can be constructed using the master regdomain tables o defer to net80211 for max antenna gain o eliminate sorting of internal channel table; now that we use ic_devdata as an index, table lookups are O(1) o remove internal copy of the country code; the public one is sufficient o remove AH_SUPPORT_11D conditional compilation; we always support 11d o remove ath_hal_ispublicsafetysku; not needed any more o remove ath_hal_isgsmsku; no more GSM stuff o move Conformance Test Limit (CTL) state from private channel to a lookup using per-band pointers cached in the private state block o remove regulatory class id support; was unused and belongs in net80211 o fix channel list construction to set IEEE80211_CHAN_NOADHOC, IEEE80211_CHAN_NOHOSTAP, and IEEE80211_CHAN_4MSXMIT o remove private channel flags CHANNEL_DFS and CHANNEL_4MS_LIMIT; these are now set in the constructed net80211 channel o store CHANNEL_NFCREQUIRED (Noise Floor Required) channel attribute in one of the driver-private flag bits of the net80211 channel o move 900MHz frequency mapping into the hal; the mapped frequency is stored in the private channel and used throughout the hal (no more mapping in the driver and/or net80211) o remove ath_hal_mhz2ieee; it's no longer needed as net80211 does the calculation and available in the net80211 channel o change noise floor calibration logic to work with compacted private channel table setup; this may require revisiting as we no longer can distinguish channel attributes (e.g. 11b vs 11g vs turbo) but since the data is used only to calculate status data we can live with it for now o change ah_getChipPowerLimits internal method to operate on a single channel instead of all channels in the private channel table o add ath_hal_gethwchannel to map a net80211 channel to a h/w frequency (always the same except for 900MHz channels) o add HAL_EEBADREG and HAL_EEBADCC status codes to better identify regulatory problems o remove CTRY_DEBUG and CTRY_DEFAULT enum's; these come from net80211 now o change ath_hal_getwirelessmodes to really return wireless modes supported by the hardware (was previously applying regulatory constraints) o return channel interference status with IEEE80211_CHANSTATE_CWINT (should change to a callback so hal api's can take const pointers) o remove some #define's no longer needed with the inclusion of <net80211/_ieee80211.h> Sponsored by: Carlson Wireless

Radar API related fixes. * For legacy NICs, the combined RSSI should be used. For earlier AR5416 NICs, use control chain 0 RSSI rather than combined RSSI.

There's apparently a bug with Merlin (AR9280) and later chipsets where putting descriptors (not buffers) across a 4k page boundary can cause issues. I've not seen it in production myself but it apparently can cause problems. So, in preparation for addressing this workaround, (re)-expose the particular HAL capability bit which marks whether the chipset has support for cross-4k- boundary transactions or not. A subsequent commit will modify the descriptor allocation to avoid allocating descriptor entries that straddle a 4k page boundary.

Add a HAL capability bit for supporting self-linked RX descriptors and disable it for the 11n chipsets. From the ath9k source: == 11N: we can no longer afford to self link the last descriptor. MAC acknowledges BA status as long as it copies frames to host buffer (or rx fifo). This can incorrectly acknowledge packets to a sender if last desc is self-linked. == Since this is useful for pre-AR5416 chips that communicate PHY errors via error frames rather than by on-chip counters, leave the support in there, but disable it for AR5416 and later.
