Commit Message

Wen Gong Sept. 24, 2019, 7:27 a.m. UTC
When firmware assert, it need coredump to analyze, this patch will
collect the register and memory info for sdio chip.

The coredump configuration is different between PCIE and SDIO for
the same reversion, so this patch add bus type to distinguish PCIE
and SDIO chip for coredump.

It has 2 type to dump firmware: fastdump and slowdump. Fastdump is
not support in old version firmware, if this, ath10k will select
slowdump for it. If firmware support fastdump, ath10k will select
fastdump for it. Version WLAN.RMH.4.4.1-00017-QCARMSWPZ-2 of
firmware begin to support fastdump.

For slow dump, ath10k_sdio_hif_diag_read can not be used, the diag
window has a limit value, it is 4 bytes and the dump's buffer length
is larger than it, it will trigger error. So this patch add
ath10k_sdio_read_mem to read 4 bytes for each time.

Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00018-QCARMSWP-1.

v2: change code style

v3: split bus type to another patch, 
remove ATH10K_BUS_ANY, 
add bus type for each layout

v4: rebase to latest commit

I did some changes in the pending branch, please check:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=de03e26479e2cf5f3e1753bda517f44910457036

Also please send dmesg output from a firmware crash, I'll add it to the
commit log as an example.

I renamed this ath10k_sdio_is_fast_dump_supported() which returns a
boolean. Also I changed all fast_dump variables to a boolean.

This error print looks like a debug message, so I removed it. If you
need it, let me know.

This also looks like a debug message so I removed it.

I did some refactoring in patch "ath10k: move enable_pll_clk call to
ath10k_core_start()" (submitted separately) so that I could change this
to ath10k_bmi_start().

Great, thanks for testing.

I also did some changes to the commit log and added an example output of
a firmware crash.

But I could not find this message anywhere in upstream ath10k so I
assumed it's from an out-of-tree patch and removed it from the example.
