ath10k: add QMI message handshake for wcn3990 client

2018-10-13T17:31:56+00:00

Add WCN3990 QMI client handshakes for Q6 integrated WLAN connectivity
subsystem. This layer is responsible for communicating qmi control
messages to wifi fw QMI service using QMI messaging protocol.

Qualcomm MSM Interface(QMI) is a messaging format used to communicate
between components running between remote processors with underlying
transport layer based on integrated chipset(shared memory) or
discrete chipset(PCI/USB/SDIO/UART).

ath10k: add support to create boardname for non-bmi target

2018-10-13T17:31:15+00:00

Add support to create the boardname for non-bmi targets
like WCN3990, which uses qmi for bdf download. This
boardname is used to parse the board data from board-2.bin.

wil6210: fix debugfs_simple_attr.cocci warnings

2018-10-13T17:28:44+00:00

Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files.

Semantic patch information:
Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file()
imposes some significant overhead as compared to
DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().

ath9k: fix RX_STAT_INC() etc macros

2018-10-13T17:27:35+00:00

A couple of macros that deal with statistics in ath9k rely on the
declaration of the 'sc' variable, which they dereference.

However, when the statistics are disabled, the new instance in
ath_cmn_process_fft() causes a warning for an unused variable:

drivers/net/wireless/ath/ath9k/common-spectral.c: In function 'ath_cmn_process_fft':
drivers/net/wireless/ath/ath9k/common-spectral.c:474:20: error: unused variable 'sc' [-Werror=unused-variable]

It's better if those macros only operate on their arguments instead of
known variable names, and adding a cast to (void) kills off that warning.

ath10k: htt: remove some dead code

2018-10-13T17:26:49+00:00

We added an unnecessary condition here in commit a904417fc876 ("ath10k:
add extended per sta tx statistics support").  "legacy_rate_idx" is a u8
so it can't be negative.  The caller doesn't pass negatives either.  I
have deleted this code.

ath10k: allocate small size dma memory in ath10k_pci_diag_write_mem

2018-10-13T17:25:49+00:00

ath10k_pci_diag_write_mem may allocate big size of the dma memory
based on the parameter nbytes. Take firmware diag download as
example, the biggest size is about 500K. In some systems, the
allocation is likely to fail because it can't acquire such a large
contiguous dma memory.

The fix is to allocate a small size dma memory. In the loop,
driver copies the data to the allocated dma memory and writes to
the destination until all the data is written.

Tested with QCA6174 PCI with
firmware-6.bin_WLAN.RM.4.4.1-00119-QCARMSWP-1, this also affects
QCA9377 PCI.
