      wil6210: fix break that is never reached because of zero'ing of a retry counter · 5b1413f0
      Colin Ian King authored 
      There is a check on the retry counter invalid_buf_id_retry that is always
false because invalid_buf_id_retry is initialized to zero on each iteration
of a while-loop.  Fix this by initializing the retry counter before the
while-loop starts.

      ath10k: fix RX of frames with broken FCS in monitor mode · ea0c3e2a
      Linus Lüssing authored 
      So far, frames were forwarded regardless of the FCS correctness leading
to userspace applications listening on the monitor mode interface to
receive potentially broken frames, even with the "fcsfail" flag unset.

By default, with the "fcsfail" flag of a monitor mode interface
unset, frames with FCS errors should be dropped. With this patch, the
fcsfail flag is taken into account correctly.

For QCA6174 PCIe, the ppdu have the correct rssi of each chain, it
indicate rssi of rx data by ath10k_htt_rx_h_signal. For sdio chip, the
rssi of each chain stored in rx management reported by firmware, the
ath10k_wmi_tlv_op_pull_mgmt_rx_ev which used for tlv wmi will get the
rssi of each chain and stored them in wmi_mgmt_rx_ev_arg, then indicate
them to mac80211. For non-tlv wmi chip, it will not get the rssi of each
chain and not indicate to mac80211, for non-tlv wmi chip, this patch will
not have impact. For tlv wmi chip, if the rssi of chain in mgmt is valid,
it will be indicate to mac80211, tested with QCA6174 PCIe/SDIO, the rssi
of 2 chain in mgmt is valid.

      ath10k: Handle "invalid" BDFs for msm8998 devices · 319c2b71
      Jeffrey Hugo authored 
      When the BDF download QMI message has the end field set to 1, it signals
the end of the transfer, and triggers the firmware to do a CRC check.  The
BDFs for msm8998 devices fail this check, yet the firmware is happy to
still use the BDF.  It appears that this error is not caught by the
downstream drive by concidence, therefore there are production devices
in the field where this issue needs to be handled otherwise we cannot
support wifi on them.  So, attempt to detect this scenario as best we can
and treat it as non-fatal.

      ath10k: Fix qmi init error handling · f8a595a8
      Jeffrey Hugo authored 
      When ath10k_qmi_init() fails, the error handling does not free the irq
resources, which causes an issue if we EPROBE_DEFER as we'll attempt to
(re-)register irqs which are already registered.

Fix this by doing a power off since we just powered on the hardware, and
freeing the irqs as error handling.

      ath10k: Handle when FW doesn't support QMI_WLFW_HOST_CAP_REQ_V01 · 501d4152
      Jeffrey Hugo authored 
      Firmware with the build id QC_IMAGE_VERSION_STRING=WLAN.HL.1.0.2-XXXX does
not support the QMI_WLFW_HOST_CAP_REQ_V01 message and will return the
QMI not supported error to the ath10k driver.  Since not supporting this
message is not fatal to the firmware nor the ath10k driver, lets catch
this particular scenario and ignore it so that we can still bring up
wifi services successfully.

      ath10k: add workqueue for RX path of sdio · 67654b26
      Wen Gong authored 
      For RX, it has two parts, one is to read data from sdio, another
is to indicate the packets to upper stack. Recently it has only
one thread to do all RX things, it results that it is sequential
for RX and low throughout, change RX to parallel for the two parts
will increase throughout.

This patch move the indication to a workqueue, it results in
significant performance improvement on RX path.

Udp rx throughout is 200Mbps without this patch, and it arrives
400Mbps with this patch.

      ath10k: change max RX bundle size from 8 to 32 for sdio · 22477652
      Wen Gong authored 
      The max bundle size support by firmware is 32, change it from 8 to 32
will help performance. This results in significant performance
improvement on RX path.

The real max rx bundle is decided in ath10k_htc_wait_target(),
it is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and the value reported
from firmware. So this change shouldn't cause any regressions with other
hardware supported by ath10k.

      ath10k: enable RX bundle receive for sdio · 8d985555
      Alagu Sankar authored 
      The existing implementation of initiating multiple sdio transfers for
receive bundling is slowing down the receive speed. Combining the
transfers using a bundle method would be ideal.

The transmission utilization ratio for sdio bus for small packet is
slow, because the space and time cost for sdio bus is same for large
length packet and small length packet. So the speed of data for large
length packet is higher than small length.

Test result of different length of data:
data packet(byte)   cost time(us)   calculated rate(Mbps)
