2015-04-07ath9k_htc: check seq number instead of cmd id for timeoutFred Chou1-1/+1
As the driver may send multiple wmi commands with identical cmd id, it is more robust to check seq number for timeout instead. Signed-off-by: Fred Chou <fred.chou.nd@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-03-30ath9k_htc: add new WMI_REG_RMW_CMDID commandOleksij Rempel1-0/+16
Since usb bus add extra delay on each request, a command with read + write requests is too expensive. We can dramtically reduce usb load by moving this command to firmware. In my tests, this patch will reduce channel scan time for about 5-10 seconds. Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2013-09-26ath9k: mark wmi_event_swba as __packedChris Metcalf1-1/+1
The other structures in wmi.h are already marked this way. Without this marking, we get an unaliged access panic in the tilegx kernel: Starting stack dump of tid 0, pid 0 (swapper) on cpu 35 at cycle 198675113844 frame 0: 0xfffffff7103ada90 ath9k_htc_swba+0x120/0x618 [ath9k_htc] frame 1: 0xfffffff7103a4b10 ath9k_wmi_event_tasklet+0x1b0/0x270 [ath9k_htc] frame 2: 0xfffffff700326570 tasklet_action+0x148/0x298 [...] Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: John W.

2011-04-28ath9k_htc: Add a new WMI command to set a rate maskSujith Manoharan1-0/+1
This patch adds WMI_BITRATE_MASK_CMDID which can be used by the set_bitrate_mask() handler. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-04-13ath9k_htc: Add a timer to cleanup WMI eventsSujith Manoharan1-0/+9
Occasionally, a WMI event would arrive ahead of the TX URB completion handler. Discarding these events would exhaust the available TX slots, so handle them by running a timer cleaning up such events. Also, timeout packets for which TX completion events have not arrived. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-13ath9k_htc: Add support for TX completionSujith Manoharan1-2/+2

2011-04-13ath9k_htc: Queue WMI eventsSujith Manoharan1-3/+4
Use a queue to handle WMI events and schedule a tasklet to process the events. This fixes the race between the WMI event ISR and the SWBA tasklet when the arrival of WMI events in quick succession could overwrite the SWBA data before the tasklet from a previous iteration could have been scheduled. Also, drain the WMI queue properly. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-13ath9k_htc: Fix WMI and beacon headerSujith Manoharan1-0/+6
Match the beacon header with that of the firmware. Also, the firmware reports the TSF for an SWBA, so store it. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-13ath9k_htc: Add a WMI command to get the firmware versionSujith Manoharan1-0/+6
Also, update the wiphy information and use the correct device pointer when registering. This would fix ethtool. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-01-04ath9k_htc: Handle FATAL eventsSujith Manoharan1-1/+2
The device has to be reset when a FATAL event is received. Not doing so would leave the card in a non-working state. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-09-15ath9k_htc: Fix memory leak on WMI event handlerRajkumar Manoharan1-5/+1
ath9k_wmi_ctrl_rx is racy with ath9k_wmi_tasklet on event notification due to which the wmi_skb may be overwritten which leads to memory leak. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-04-26ath9k_htc: Increase WMI timeout valueSujith1-2/+2
Completion of WMI commands take a longer time on some platforms. Increase the timeout value to handle this. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-04-16ath9k_htc: Fix sparse endian warningsSujith1-5/+5
This patch fixes a bunch of endian issues that were exposed by sparse. It's a miracle that the driver worked at all till now. The Lord be praised. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-04-16ath9k_htc: Handle WMI timeouts properlySujith1-0/+1
If a WMI command has timed out for some reason, a late WMI response would end up updating the response region of a new WMI request that has been issued in the meantime. Fix this race condition by dropping a WMI response if a new WMI command has been issued. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-04-16ath9k_htc: Implement multiple register write supportSujith1-0/+12
This patch adds support for writing multiple registers in a single USB command. Specific calls from the HW code that performs multiple register writes would be modified to make use of this in subsequent patches.
