commit 92cc5d00a431e96e5a49c0b97e5ad4fa7536bd4b upstream.
Apparently despite it being marked inline, the compiler
may not inline __down_read_common() which makes it difficult
to identify the cause of lock contention, as the blocked
function in traceevents will always be listed as
__down_read_common().
So this patch adds __always_inline annotation to the common
function (as well as the inlined helper callers) to force it to
be inlined so the blocking function will be listed (via Wchan)
in traceevents.

[ Upstream commit 84822215acd15bd86a7759a835271e63bba83a7b ]
The WCD938x comes with three devices on two Linux drivers:
1. RX Soundwire device (wcd938x-sdw.c driver),
2. TX Soundwire device, which is used to access devices via regmap (also
wcd938x-sdw.c driver),
3. platform device (wcd938x.c driver) - glue and component master,
actually having most of the code using TX Soundwire device regmap.
When RX and TX Soundwire devices probe, the component master (platform
device) bind tries to write micbias configuration via TX Soundwire
regmap. This might happen before TX Soundwire enumerates, so the regmap
access fails. On Qualcomm SM8550 board with WCD9385:
qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops)
wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops)
qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow
Fix the issue by:
1. Moving the regmap creation from platform device to TX Soundwire
device. The regmap settings are moved as-is with one difference:
making the wcd938x_regmap_config const.
2. Using regmap in cache only mode till the actual TX Soundwire device
enumerates and then sync the regmap cache.

On my RTW8821CU chipset rfe_option reads as 0x22. Looking at the
vendor driver suggests that the field width of rfe_option is 5 bit,
so rfe_option should be masked with 0x1f.
Without this the rfe_option comparisons with 2 further down the
driver evaluate as false when they should really evaluate as true.
The effect is that 2G channels do not work.
rfe_option is also used as an array index into rtw8821c_rfe_defs[].
rtw8821c_rfe_defs[34] (0x22) was added as part of adding USB support,
likely because rfe_option reads as 0x22. As this now becomes 0x2,
rtw8821c_rfe_defs[34] is no longer used and can be removed.
Note that this might not be the whole truth. In the vendor driver
there are indeed places where the unmasked rfe_option value is used.
However, the driver has several places where rfe_option is tested
with the pattern if (rfe_option == 2 || rfe_option == 0x22) or
if (rfe_option == 4 || rfe_option == 0x24), so that rfe_option BIT(5)
has no influence on the code path taken. We therefore mask BIT(5)
out from rfe_option entirely until this assumption is proved wrong
by some chip variant we do not know yet.

If the hangcheck timer expires, check if the fw's position in the

allow it up to three additional "extensions" to it's alotted time.
The intention is to continue to catch "shader stuck in a loop" type
hangs quickly, but allow more time for things that are actually
making forward progress.
Because we need to sample the CP state twice to detect if there has
not been progress, this also cuts the the timer's duration in half.
v2: Fix typo (REG_A6XX_CP_CSQ_IB2_STAT), add comment
v3: Only halve hangcheck timer duration for generations which
support progress detection (hdanton); removed unused a5xx
progress (without knowing how to adjust for data buffered
in ROQ it is too likely to report a false negative)

Let's reduce the complexity of mixed use of rb_tree in victim_entry from
extent_cache and discard_cmd.
This should fix arm32 memory alignment issue caused by shared rb_entry.

commit 3eeca5e5f3100435b06a5b5d86daa3d135a8a4bd upstream.
The adreno_load_gpu() path is guarded by an error check on
adreno_load_fw(). This function is responsible for loading
Qualcomm-only-signed binaries (e.g. SQE and GMU FW for A6XX), but it
does not take the vendor-signed ZAP blob into account.
By embedding the SQE (and GMU, if necessary) firmware into the
initrd/kernel, we can trigger and unfortunate path that would not bail
out early and proceed with gpu->hw_init(). That will fail, as the ZAP
loader path will not find the firmware and return back to
adreno_load_gpu().
This error path involves pm_runtime_put_sync() which then calls idle()
instead of suspend(). This is suboptimal, as it means that we're not
going through the clean shutdown sequence. With at least A619_holi, this
makes the GPU not wake up until it goes through at least one more
start-fail-stop cycle. The pm_runtime_put_sync that appears in the error
path actually does not guarantee that because of the earlier enabling of
runtime autosuspend.
Fix that by using pm_runtime_put_sync_suspend to force a clean shutdown.
Test cases:
1. All firmware baked into kernel
2. error loading ZAP fw in initrd -> load from rootfs at DE start
Both succeed on A619_holi (SM6375) and A630 (SDM845).

commit 17d793f3ed53080dab6bbeabfc82de890c901001 upstream.
To fully utilize the BT polling/refresh rate, a few input events
are sent together to reduce event delay. This causes issue to the
timestamp generated by input_sync since all the events in the same
packet would pretty much have the same timestamp. This patch inserts
time interval to the events by averaging the total time used for
sending the packet.
This decision was mainly based on observing the actual time interval
between each BT polling. The interval doesn't seem to be constant,
due to the network and system environment. So, using solutions other
than averaging doesn't end up with valid timestamps.

commit 2210af50ae7f4104269dfde7bafbbfbacdbe1a2b upstream.
All microcode runs a basic validation after it's been loaded. Each
IP block as part of init will run both.
Introduce a wrapper for request_firmware and amdgpu_ucode_validate.
This wrapper will also remap any error codes from request_firmware
to -ENODEV. This is so that early_init will fail if firmware couldn't
be loaded instead of the IP block being disabled.

Add an early_init phase to MES for fetching and validating microcode
from the filesystem.
If MES microcode is required but not available during early init, the
firmware framebuffer will have already been released and the screen will
freeze.
Move the request for MES microcode into the early_init phase
so that if it's not available, early_init will fail.

commit b504f99ccaa64da364443431e388ecf30b604e38 upstream.
[Description]
- Due to bandwidth / arbitration issues at 200Mhz DCFCLK,
we want to enforce minimum 60us of prefetch to avoid
intermittent underflow issues
- Since 60us prefetch is already enforced for UCLK DPM0,
and many DCFCLK's > 200Mhz are mapped to UCLK DPM1, in
theory there should not be any UCLK DPM regressions by
enforcing greater prefetch
