Try to create some sort of consistency in how the routings to find the multicast hash are written. There are still two distinct algorithms used, and there actually isn't any reason each driver should have its own copy of this function as they could all share one copy of it (if it grew an additional argument).

Attempt to fix a problem with receiving packets on USB ethernet interfaces. Packets are received inside USB bulk transfer callbacks, which run at splusb() (actually splbio()). The packet input queues are meant to be manipulated at splimp(). However the locking apparently breaks down under certain circumstances and the input queues can get trampled. There's a similar problem with if_ppp, which is driven by hardware/tty interrupts from the serial driver, but which must also manipulate the packet input queues at splimp(). The fix there is to use a netisr, and that's the fix I used here. (I can hear you groaning back there. Hush up.) The usb_ethersubr module maintains a single queue of its own. When a packet is received in the USB callback routine, it's placed on this queue with usb_ether_input(). This routine also schedules a soft net interrupt with schednetisr(). The ISR routine then runs later, at splnet, outside of the USB callback/interrupt context, and passes the packet to ether_input(), hopefully in a safe manner. The reason this is implemented as a separate module is that there are a limited number of NETISRs that we can use, and snarfing one up for each driver that needs it is wasteful (there will be three once I get the CATC driver done). It also reduces code duplication to a certain small extent. Unfortunately, it also needs to be linked in with the usb.ko module in order for the USB ethernet drivers to share it. Also removed some uneeded includes from if_aue.c and if_kue.c Fix suggested by: peter Not rejected as a hairbrained idea by: n_hibma

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

* The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet
* support: the control endpoint for reading/writing registers, burst
* read endpoint for packet reception, burst write for packet transmission
* and one for "interrupts." The chip uses the same RX filter scheme
* as the other ADMtek ethernet parts: one perfect filter entry for the
* the station address and a 64-bit multicast hash table. The chip supports
* both MII and HomePNA attachments.
*
* Since the maximum data transfer speed of USB is supposed to be 12Mbps,
* you're never really going to get 100Mbps speeds from this device. I
* think the idea is to allow the device to connect to 10 or 100Mbps
* networks, not necessarily to provide 100Mbps performance. Also, since
* the controller uses an external PHY chip, it's possible that board
* designers might simply choose a 10Mbps PHY.
*
* Registers are accessed using usbd_do_request(). Packet transfers are
* done using usbd_transfer() and friends.

Depend on miibus. Note that if_aue doesn't strictly depend on usb because it uses the method interface for calls rather than using internal symbols, and because it's a child driver of usb and therefore will not try and do anything unless the parent usb code is loaded at some point. if_aue does strictly depend on miibus as it will fail to link if it is missing.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c.

More USB ethernet tweaks: - Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the following improvements: o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP quirk. This allows drivers to specify busy waiting only for certain transfers (namely control transfers for reading/writing registers and stuff). o New USBD_FORCE_SHORT_XFER flag can be used to deal with devices like the ADMtek Pegasus that sense the end of bulk OUT transfers in a special way (if a transfer is exactly a multiple of 64 bytes in size, you need to send an extra empty packet to terminate the transfer). o usbd_open_pipe_intr() now accepts an interval argument which can be used to change the rate at which the interrupt callback routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the value specified in the device's config data, but drivers can override it if needed. - Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions. - Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all control transfers. We no longer force the non-tsleep hack for bulk transfers since these are done asynchronously anyway. - Removed quirk entry fiddling from if_aue and if_kue since we don't need it anymore now that we have the USBD_NO_TSLEEP flag. - Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to usbd_open_pipe_intr(). - Add a flag to the softc struct in the ethernet drivers to indicate when a device has been detached, and use this flag to perform tests to prevent the drivers from trying to do control transfers if this is the case. This is necessary because calling if_detach() with INET6 enabled will eventually result in a call to the driver's ioctl() routine to delete the multicast groups on the interface, which will result in attempts to perform control transfers. (It's possible this also happens even without INET6 support enabled.) This is pointless since we know that if the detach method has been called, the hardware has been unplugged. - Changed watchdog timeout routines to just call the driver init routines to initialize the device states without trying to close and re-open the pipes. This is partly because we don't want to frob things at interrupt context, but also because this doesn't seem to work right and I don't want to panic the system just because a USB device may have stopped responding. - Fix aue_rxeof() to be a little smarter about detecting when a double transfer is needed. Unfortunately, the design of the chip makes it hard to get this exactly right. Hopefully, this will go away once either Nick or Lennart finds the bug in the uhci driver that makes this ugly hack necessary. - Also sync usbdevs with NetBSD.

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

More USB ethernet tweaks: - Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the following improvements: o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP quirk. This allows drivers to specify busy waiting only for certain transfers (namely control transfers for reading/writing registers and stuff). o New USBD_FORCE_SHORT_XFER flag can be used to deal with devices like the ADMtek Pegasus that sense the end of bulk OUT transfers in a special way (if a transfer is exactly a multiple of 64 bytes in size, you need to send an extra empty packet to terminate the transfer). o usbd_open_pipe_intr() now accepts an interval argument which can be used to change the rate at which the interrupt callback routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the value specified in the device's config data, but drivers can override it if needed. - Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions. - Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all control transfers. We no longer force the non-tsleep hack for bulk transfers since these are done asynchronously anyway. - Removed quirk entry fiddling from if_aue and if_kue since we don't need it anymore now that we have the USBD_NO_TSLEEP flag. - Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to usbd_open_pipe_intr(). - Add a flag to the softc struct in the ethernet drivers to indicate when a device has been detached, and use this flag to perform tests to prevent the drivers from trying to do control transfers if this is the case. This is necessary because calling if_detach() with INET6 enabled will eventually result in a call to the driver's ioctl() routine to delete the multicast groups on the interface, which will result in attempts to perform control transfers. (It's possible this also happens even without INET6 support enabled.) This is pointless since we know that if the detach method has been called, the hardware has been unplugged. - Changed watchdog timeout routines to just call the driver init routines to initialize the device states without trying to close and re-open the pipes. This is partly because we don't want to frob things at interrupt context, but also because this doesn't seem to work right and I don't want to panic the system just because a USB device may have stopped responding. - Fix aue_rxeof() to be a little smarter about detecting when a double transfer is needed. Unfortunately, the design of the chip makes it hard to get this exactly right. Hopefully, this will go away once either Nick or Lennart finds the bug in the uhci driver that makes this ugly hack necessary. - Also sync usbdevs with NetBSD.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development.

More USB ethernet tweaks: - Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the following improvements: o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP quirk. This allows drivers to specify busy waiting only for certain transfers (namely control transfers for reading/writing registers and stuff). o New USBD_FORCE_SHORT_XFER flag can be used to deal with devices like the ADMtek Pegasus that sense the end of bulk OUT transfers in a special way (if a transfer is exactly a multiple of 64 bytes in size, you need to send an extra empty packet to terminate the transfer). o usbd_open_pipe_intr() now accepts an interval argument which can be used to change the rate at which the interrupt callback routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the value specified in the device's config data, but drivers can override it if needed. - Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions. - Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all control transfers. We no longer force the non-tsleep hack for bulk transfers since these are done asynchronously anyway. - Removed quirk entry fiddling from if_aue and if_kue since we don't need it anymore now that we have the USBD_NO_TSLEEP flag. - Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to usbd_open_pipe_intr(). - Add a flag to the softc struct in the ethernet drivers to indicate when a device has been detached, and use this flag to perform tests to prevent the drivers from trying to do control transfers if this is the case. This is necessary because calling if_detach() with INET6 enabled will eventually result in a call to the driver's ioctl() routine to delete the multicast groups on the interface, which will result in attempts to perform control transfers. (It's possible this also happens even without INET6 support enabled.) This is pointless since we know that if the detach method has been called, the hardware has been unplugged. - Changed watchdog timeout routines to just call the driver init routines to initialize the device states without trying to close and re-open the pipes. This is partly because we don't want to frob things at interrupt context, but also because this doesn't seem to work right and I don't want to panic the system just because a USB device may have stopped responding. - Fix aue_rxeof() to be a little smarter about detecting when a double transfer is needed. Unfortunately, the design of the chip makes it hard to get this exactly right. Hopefully, this will go away once either Nick or Lennart finds the bug in the uhci driver that makes this ugly hack necessary. - Also sync usbdevs with NetBSD.

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep().

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light.

Minor enhancement: set the 'dual link LED' bit in the auxmode register of the Broadcom BCM5201 PHY on the LinkSys USB100TX adapter so that the link LED correctly (lights up amber for 10mbps link, green for 100mbps link). Note that the sticker on the bottom of the adapter says amber for 10 and green for 100, but the appendix in the manual that comes with the adapter says green for 10 and amber for 100. Given that there doesn't seem to be any way to make the hardware produce the latter combination, I think it's safe to say the sticker is right and the manual is wrong. I'm just shocked, shocked I tell you.

Try to create some sort of consistency in how the routings to find the multicast hash are written. There are still two distinct algorithms used, and there actually isn't any reason each driver should have its own copy of this function as they could all share one copy of it (if it grew an additional argument).

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

Be a bit more discriminating when trying to decide when to screen out certain PHY addresses in aue_miibus_readreg(). Not all adapters based on the Pegasus chip may have their PHYs wired for the same MII bus addresses: the logic that I used for my ADMtek eval board might not apply to other adapters, so make sure to only use it if this is really an ADMtek eval board (check the vendor/device ID). This will hopefully make the LinkSys USB100TX adapter work correctly.

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

Attempt to fix a problem with receiving packets on USB ethernet interfaces. Packets are received inside USB bulk transfer callbacks, which run at splusb() (actually splbio()). The packet input queues are meant to be manipulated at splimp(). However the locking apparently breaks down under certain circumstances and the input queues can get trampled. There's a similar problem with if_ppp, which is driven by hardware/tty interrupts from the serial driver, but which must also manipulate the packet input queues at splimp(). The fix there is to use a netisr, and that's the fix I used here. (I can hear you groaning back there. Hush up.) The usb_ethersubr module maintains a single queue of its own. When a packet is received in the USB callback routine, it's placed on this queue with usb_ether_input(). This routine also schedules a soft net interrupt with schednetisr(). The ISR routine then runs later, at splnet, outside of the USB callback/interrupt context, and passes the packet to ether_input(), hopefully in a safe manner. The reason this is implemented as a separate module is that there are a limited number of NETISRs that we can use, and snarfing one up for each driver that needs it is wasteful (there will be three once I get the CATC driver done). It also reduces code duplication to a certain small extent. Unfortunately, it also needs to be linked in with the usb.ko module in order for the USB ethernet drivers to share it. Also removed some uneeded includes from if_aue.c and if_kue.c Fix suggested by: peter Not rejected as a hairbrained idea by: n_hibma

There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it.

More USB ethernet tweaks: - Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the following improvements: o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP quirk. This allows drivers to specify busy waiting only for certain transfers (namely control transfers for reading/writing registers and stuff). o New USBD_FORCE_SHORT_XFER flag can be used to deal with devices like the ADMtek Pegasus that sense the end of bulk OUT transfers in a special way (if a transfer is exactly a multiple of 64 bytes in size, you need to send an extra empty packet to terminate the transfer). o usbd_open_pipe_intr() now accepts an interval argument which can be used to change the rate at which the interrupt callback routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the value specified in the device's config data, but drivers can override it if needed. - Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions. - Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all control transfers. We no longer force the non-tsleep hack for bulk transfers since these are done asynchronously anyway. - Removed quirk entry fiddling from if_aue and if_kue since we don't need it anymore now that we have the USBD_NO_TSLEEP flag. - Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to usbd_open_pipe_intr(). - Add a flag to the softc struct in the ethernet drivers to indicate when a device has been detached, and use this flag to perform tests to prevent the drivers from trying to do control transfers if this is the case. This is necessary because calling if_detach() with INET6 enabled will eventually result in a call to the driver's ioctl() routine to delete the multicast groups on the interface, which will result in attempts to perform control transfers. (It's possible this also happens even without INET6 support enabled.) This is pointless since we know that if the detach method has been called, the hardware has been unplugged. - Changed watchdog timeout routines to just call the driver init routines to initialize the device states without trying to close and re-open the pipes. This is partly because we don't want to frob things at interrupt context, but also because this doesn't seem to work right and I don't want to panic the system just because a USB device may have stopped responding. - Fix aue_rxeof() to be a little smarter about detecting when a double transfer is needed. Unfortunately, the design of the chip makes it hard to get this exactly right. Hopefully, this will go away once either Nick or Lennart finds the bug in the uhci driver that makes this ugly hack necessary. - Also sync usbdevs with NetBSD.

The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development.

Attempt to fix a problem with receiving packets on USB ethernet interfaces. Packets are received inside USB bulk transfer callbacks, which run at splusb() (actually splbio()). The packet input queues are meant to be manipulated at splimp(). However the locking apparently breaks down under certain circumstances and the input queues can get trampled. There's a similar problem with if_ppp, which is driven by hardware/tty interrupts from the serial driver, but which must also manipulate the packet input queues at splimp(). The fix there is to use a netisr, and that's the fix I used here. (I can hear you groaning back there. Hush up.) The usb_ethersubr module maintains a single queue of its own. When a packet is received in the USB callback routine, it's placed on this queue with usb_ether_input(). This routine also schedules a soft net interrupt with schednetisr(). The ISR routine then runs later, at splnet, outside of the USB callback/interrupt context, and passes the packet to ether_input(), hopefully in a safe manner. The reason this is implemented as a separate module is that there are a limited number of NETISRs that we can use, and snarfing one up for each driver that needs it is wasteful (there will be three once I get the CATC driver done). It also reduces code duplication to a certain small extent. Unfortunately, it also needs to be linked in with the usb.ko module in order for the USB ethernet drivers to share it. Also removed some uneeded includes from if_aue.c and if_kue.c Fix suggested by: peter Not rejected as a hairbrained idea by: n_hibma

The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

Fix a bug in the uhci driver that breaks large bulk IN transfers. The uhci_check_intr() routine needs to be more careful about deciding when the end of a transfer has been detected. This allows me to remove the nasty workaround code from if_aue and if_cue. Receive performance is now much better for these adapters (500KB/sec vs. 350KB/sec). Also removed unused KUE_CUTOFF define from if_kuereg.h. Submitted by: Lennart Augustsson Reviewed by: n_hibma

My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away.

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.

More USB ethernet tweaks: - Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the following improvements: o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP quirk. This allows drivers to specify busy waiting only for certain transfers (namely control transfers for reading/writing registers and stuff). o New USBD_FORCE_SHORT_XFER flag can be used to deal with devices like the ADMtek Pegasus that sense the end of bulk OUT transfers in a special way (if a transfer is exactly a multiple of 64 bytes in size, you need to send an extra empty packet to terminate the transfer). o usbd_open_pipe_intr() now accepts an interval argument which can be used to change the rate at which the interrupt callback routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the value specified in the device's config data, but drivers can override it if needed. - Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions. - Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all control transfers. We no longer force the non-tsleep hack for bulk transfers since these are done asynchronously anyway. - Removed quirk entry fiddling from if_aue and if_kue since we don't need it anymore now that we have the USBD_NO_TSLEEP flag. - Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to usbd_open_pipe_intr(). - Add a flag to the softc struct in the ethernet drivers to indicate when a device has been detached, and use this flag to perform tests to prevent the drivers from trying to do control transfers if this is the case. This is necessary because calling if_detach() with INET6 enabled will eventually result in a call to the driver's ioctl() routine to delete the multicast groups on the interface, which will result in attempts to perform control transfers. (It's possible this also happens even without INET6 support enabled.) This is pointless since we know that if the detach method has been called, the hardware has been unplugged. - Changed watchdog timeout routines to just call the driver init routines to initialize the device states without trying to close and re-open the pipes. This is partly because we don't want to frob things at interrupt context, but also because this doesn't seem to work right and I don't want to panic the system just because a USB device may have stopped responding. - Fix aue_rxeof() to be a little smarter about detecting when a double transfer is needed. Unfortunately, the design of the chip makes it hard to get this exactly right. Hopefully, this will go away once either Nick or Lennart finds the bug in the uhci driver that makes this ugly hack necessary. - Also sync usbdevs with NetBSD.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light.

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available.

There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory

More USB ethernet tweaks: - Sync ohci, uhci and usbdi modules with NetBSD in order to obtain the following improvements: o New USBD_NO_TSLEEP flag can be used in place of UQ_NO_TSLEEP quirk. This allows drivers to specify busy waiting only for certain transfers (namely control transfers for reading/writing registers and stuff). o New USBD_FORCE_SHORT_XFER flag can be used to deal with devices like the ADMtek Pegasus that sense the end of bulk OUT transfers in a special way (if a transfer is exactly a multiple of 64 bytes in size, you need to send an extra empty packet to terminate the transfer). o usbd_open_pipe_intr() now accepts an interval argument which can be used to change the rate at which the interrupt callback routine is invoked. Specifying USBD_DEFAULT_INTERVAL uses the value specified in the device's config data, but drivers can override it if needed. - Change if_aue to use USBD_FORCE_SHORT_XFER for packet transmissions. - Change if_aue, if_kue and if_cue to use USBD_NO_TSLEEP for all control transfers. We no longer force the non-tsleep hack for bulk transfers since these are done asynchronously anyway. - Removed quirk entry fiddling from if_aue and if_kue since we don't need it anymore now that we have the USBD_NO_TSLEEP flag. - Tweak ulpt, uhid, ums and ukbd drivers to use the new arg to usbd_open_pipe_intr(). - Add a flag to the softc struct in the ethernet drivers to indicate when a device has been detached, and use this flag to perform tests to prevent the drivers from trying to do control transfers if this is the case. This is necessary because calling if_detach() with INET6 enabled will eventually result in a call to the driver's ioctl() routine to delete the multicast groups on the interface, which will result in attempts to perform control transfers. (It's possible this also happens even without INET6 support enabled.) This is pointless since we know that if the detach method has been called, the hardware has been unplugged. - Changed watchdog timeout routines to just call the driver init routines to initialize the device states without trying to close and re-open the pipes. This is partly because we don't want to frob things at interrupt context, but also because this doesn't seem to work right and I don't want to panic the system just because a USB device may have stopped responding. - Fix aue_rxeof() to be a little smarter about detecting when a double transfer is needed. Unfortunately, the design of the chip makes it hard to get this exactly right. Hopefully, this will go away once either Nick or Lennart finds the bug in the uhci driver that makes this ugly hack necessary. - Also sync usbdevs with NetBSD.

Fix a bug in the uhci driver that breaks large bulk IN transfers. The uhci_check_intr() routine needs to be more careful about deciding when the end of a transfer has been detected. This allows me to remove the nasty workaround code from if_aue and if_cue. Receive performance is now much better for these adapters (500KB/sec vs. 350KB/sec).

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait.

Convert the USB ethernet drivers to use mutexes. Also convert usb_ethersubr.c. This module maintains two queues for packets which are each protected with one mutex. These are all the changes I can do for now. Removing the USBD_NO_TSLEEP flag doesn't work yet: when I tried it, the system would usually freeze up after a NIC had been operating for a while. The usb_ethersubr module itself ought to go away; this is the next thing I need to test.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light.

This commit adds device driver support for the ADMtek AN986 Pegasus USB ethernet chip. Adapters that use this chip include the LinkSys USB100TX. There are a few others, but I'm not certain of their availability in the U.S. I used an ADMtek eval board for development. Note that while the ADMtek chip is a 100Mbps device, you can't really get 100Mbps speeds over USB. Regardless, this driver uses miibus to allow speed and duplex mode selection as well as autonegotiation. Building and kldloading the driver as a module is also supported. Note that in order to make this driver work, I had to make what some may consider an ugly hack to sys/dev/usb/usbdi.c. The usbd_transfer() function will use tsleep() for synchronous transfers that don't complete right away. This is a problem since there are times when we need to do sync transfers from an interrupt context (i.e. when reading registers from the MAC via the control endpoint), where tsleep() us a no-no. My hack allows the driver to have the code poll for transfer completion subject to the xfer->timeout timeout rather that calling tsleep(). This hack is controlled by a quirk entry and is only enabled for the ADMtek device. Now, I'm sure there are a few of you out there ready to jump on me and suggest some other approach that doesn't involve a busy wait. The only solution that might work is to handle the interrupts in a kernel thread, where you may have something resembling a process context that makes it okay to tsleep(). This is lovely, except we don't have any mechanism like that now, and I'm not about to implement such a thing myself since it's beyond the scope of driver development. (Translation: I'll be damned if I know how to do it.) If FreeBSD ever aquires such a mechanism, I'll be glad to revisit the driver to take advantage of it. In the meantime, I settled for what I perceived to be the solution that involved the least amount of code changes. In general, the hit is pretty light. Also note that my only USB test box has a UHCI controller: I haven't I don't have a machine with an OHCI controller available. Highlights: - Updated usb_quirks.* to add UQ_NO_TSLEEP quirk for ADMtek part. - Updated usbdevs and regenerated generated files - Updated HARDWARE.TXT and RELNOTES.TXT files - Updated sysinstall/device.c and userconfig.c - Updated kernel configs -- device aue0 is commented out by default - Updated /sys/conf/files - Added new kld module directory
