2013-03-18ath9k: limit tx path hang check to normal data queuesFelix Fietkau1-13/+13
The beacon and multicast-buffer queues are managed by the beacon tasklet, and the generic tx path hang check does not help in any way here. Running it on those queues anyway can introduce some race conditions leading to unnecessary chip resets.

2013-03-18ath9k_hw: revert chainmask to user configuration after calibrationFelix Fietkau1-0/+4
The commit 'ath9k_hw: fix calibration issues on chainmask that don't include chain 0' changed the hardware chainmask to the chip chainmask for the duration of the calibration, but the revert to user configuration in the reset path runs too early. That causes some issues with limiting the number of antennas (including spurious failure in hardware-generated packets). Fix this by reverting the chainmask after the essential parts of the calibration that need the workaround, and before NF calibration is run.

2013-03-18ath6kl: Fix the byte alignment rule to avoid loss of bytes in a TCP segmentMyoungje Kim2-5/+7
Either first 3 bytes of the first received tcp segment or last one over MTU size file can be loss due to the byte alignment problem. Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header alignment' in the patch "Fix buffer alignment for scatter-gather I/O"(1df94a857), there exists the bytes loss issue which means that it will be truncated 3 bytes in the transmitted file contents if a file which has over MTU size is transferred through TCP/IP stack. It doesn't look like TCP/IP stack bug of 3.5 or the latest version of kernel but the byte alignment issue. This patch is to use the roundup() function for the byte alignment rather than the predefined ATH6KL_HTC_ALIGN_BYTES. kvalo: fixed indentation Signed-off-by: Myoungje Kim <mjei78@gmail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-03-18ath6kl: remove false check from ath6kl_rx()Kalle Valo1-1/+1
Dan found a check from ath6kl_rx() which doesn't make any sense at all: " 1327 if (status || !(skb->data + HTC_HDR_LENGTH)) { ^^^^^^^^^^^^^^^^^^^^^^^^^^ skb->data is a pointer. This pointer math is always going to be false. Should it be testing "packet->act_len < HTC_HDR_LENGTH" or something?" I don't know what the check really was supposed to do, but I think Dan's guess is right. Fix it accordingly.

Dan reported that smatch found a possible issue in ath6kl_wmi_beginscan_cmd() where we might access sc->supp_rates beyond the end. It shouldn't happen as ar->wiphy->bands always have just the first two bands set, but add an extra check just to be sure.

2013-03-18ath6kl: add tracing support to debug message macrosKalle Valo2-4/+50
Now all log messages are sent through the tracing infrastruture as well. Tracing point doesn't follow debug_mask module parameter, instead it sends all debug messages, so once you enable ath6kl_log_dbg tracing point you will get a lot of messages. Needs to be discussed if this is sensible or not. The overhead should be small enough and we anyway include debug level as well so it's easy to filter in user space. I wasn't really sure what to do with ath6kl_dbg_dump() and for now decided that it also sends the buffer to user space. But most likely in the future ath6kl_dbg_dump() should go away in favor of using proper tracing points, but we will see. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2013-03-18ath6kl: adding tracing points for htc_mboxKalle Valo2-1/+76
Add tracing points for htc layer, just dumping the packets to user space. I wasn't really sure what to do with the status value, it might not always be accurate, but I included it anyway.

2013-03-18ath6kl: add tracing point for hif irqsKalle Valo2-0/+23
Add a tracing point for hif irq and dump the register content to user space. This is in hif.c as we could use the same code also with SPI but, as ath6kl doesn't SPI and most likely never will be, this is used just by SDIO so name the trace point as ath6kl_sdio_irq to make it easier to manage filters.

Julien reported that ar6004 usb device fails to initialise after host has been rebooted and power is still on for the ar6004 device. He found out that doing a cold reset fixes the issue. I wasn't sure what would be the best way to detect if target needs a reset so I settled on checking a timeout from htc_wait_recv_ctrl_message().

2013-03-13wil6210: new SW resetVladimir Kondratiev4-23/+17
New firmware allows for shorter SW reset procedure. After SW reset, FW raises "fw done" IRQ, at this moment mailbox control structures are initialized, driver caches it. New status bit wil_status_reset_done introduced to track completion of the reset. It is set by "fw ready" irq, and required for WMI rx flow to access control structures. WMI Tx flow protected by other status bit, wil_status_fwready. It can't be set before wil_status_reset_done is set by design.
