      wcn36xx: use READ_ONCE() to access desc->ctrl · 9ff6fde8
      由 Daniel Mack 提交于 
      When accessing shared memory to check for the stat of submitted
descriptors, make sure to use READ_ONCE(). This will guarantee the
compiler treats these memory locations as volatile and doesn't apply
any caching.

While this doesn't fix any particular problem I ran into, it's best
practice to do it this way.

Note that this patch also removes the superflous extra condition check
in the do-while loop in reap_tx_dxes(), as the loop will break
instantly anyway in that case.

      ath10k: add inlined wrappers for htt tx ops · 5df6e131
      由 Erik Stromdahl 提交于 
      These wrappers makes the HTT ops align better with the HIF ops
(where similar wrappers are used).

It also makes it easier for a target to have unsupported ops
(by letting the corresponding function pointer be NULL).

      ath10k: search all IEs for variant before falling back · c8489668
      由 Thomas Hebb 提交于 
      commit f2593cb1 ("ath10k: Search SMBIOS for OEM board file
extension") added a feature to ath10k that allows Board Data File
(BDF) conflicts between multiple devices that use the same device IDs
but have different calibration requirements to be resolved by allowing
a "variant" string to be stored in SMBIOS [and later device tree, added
by commit d06f26c5 ("ath10k: search DT for qcom,ath10k-calibration-
variant")] that gets appended to the ID stored in board-2.bin.

This original patch had a regression, however. Namely that devices with
a variant present in SMBIOS that didn't need custom BDFs could no longer
find the default BDF, which has no variant appended. The patch was
reverted and re-applied with a fix for this issue in commit 1657b8f8
("search SMBIOS for OEM board file extension").

But the fix to fall back to a default BDF introduced another issue: the
driver currently parses IEs in board-2.bin one by one, and for each one
it first checks to see if it matches the ID with the variant appended.
If it doesn't, it checks to see if it matches the "fallback" ID with no
variant. If a matching BDF is found at any point during this search, the
search is terminated and that BDF is used. The issue is that it's very
possible (and is currently the case for board-2.bin files present in the
ath10k-firmware repository) for the default BDF to occur in an earlier
IE than the variant-specific BDF. In this case, the current code will
happily choose the default BDF even though a better-matching BDF is
present later in the file.

This patch fixes the issue by first searching the entire file for the ID
with variant, and searching for the fallback ID only if that search
fails. It also includes some code cleanup in the area, as
ath10k_core_fetch_board_data_api_n() no longer does its own string
mangling to remove the variant from an ID, instead leaving that job to a
new flag passed to ath10k_core_create_board_name().

I've tested this patch on a QCA4019 and verified that the driver behaves
correctly for 1) both fallback and variant BDFs present, 2) only fallback
BDF present, and 3) no matching BDFs present.
