x86/amd_nb: Add PCI ID for family 19h model 78h
commit
23a5b8bb022c1e071ca91b1a9c10f0ad6a0966e9 upstream.
Commit
310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe")
switched to using amd_smn_read() which relies upon the misc PCI ID used
by DF function 3 being included in a table. The ID for model 78h is
missing in that table, so amd_smn_read() doesn't work.
Add the missing ID into amd_nb, restoring s2idle on this system.

ext4: fix invalid free tracking in ext4_xattr_move_to_block()
commit
b87c7cdf2bed4928b899e1ce91ef0d147017ba45 upstream.
In ext4_xattr_move_to_block(), the value of the extended attribute
which we need to move to an external block may be allocated by
kvmalloc() if the value is stored in an external inode. So at the end
of the function the code tried to check if this was the case by
testing entry->e_value_inum.
However, at this point, the pointer to the xattr entry is no longer
valid, because it was removed from the original location where it had
been stored. So we could end up calling kvfree() on a pointer which
was not allocated by kvmalloc(); or we could also potentially leak
memory by not freeing the buffer when it should be freed. Fix this by
storing whether it should be freed in a separate variable.

ext4: fix lockdep warning when enabling MMP
commit
949f95ff39bf188e594e7ecd8e29b82eb108f5bf upstream.
When we enable MMP in ext4_multi_mount_protect() during mount or
remount, we end up calling sb_start_write() from write_mmp_block(). This
triggers lockdep warning because freeze protection ranks above s_umount
semaphore we are holding during mount / remount. The problem is harmless
because we are guaranteed the filesystem is not frozen during mount /
remount but still let's fix the warning by not grabbing freeze
protection from ext4_multi_mount_protect().

The ext4_dirhash() will *almost* never fail, especially when the hash
tree feature was first introduced. However, with the addition of
support of encrypted, casefolded file names, that function can most
certainly fail today.
So make sure the callers of ext4_dirhash() properly check for
failures, and reflect the errors back up to their callers.

When ext4_iomap_overwrite_begin() calls ext4_iomap_begin() map blocks may

later because "iomap->type ! = IOMAP_MAPPED" triggers WARN_ON(). When ext4
iomap_begin() returns an error, it is normal that the type of iomap->type

When using cached extent stored in extent status tree in tree->cache_es
another process holding ei->i_es_lock for reading can be racing with us
setting new value of tree->cache_es. If the compiler would decide to
refetch tree->cache_es at an unfortunate moment, it could result in a
bogus in_range() check. Fix the possible race by using READ_ONCE() when
using tree->cache_es only under ei->i_es_lock for reading.

locking/rwsem: Add __always_inline annotation to __down_read_common() and inlined callers
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.

ASoC: codecs: wcd938x: fix accessing regmap on unattached devices
[ 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.

Update the decide_zstate_support function to allow for specifying
these modes based on the Z8 threshold.
DCN31 has z-state disabled, but still update the legacy code to
map z8_only = disallow and z10_z8_only = z10_only to keep the support
the same.

drm/i915: Check pipe source size when using skl+ scalers
[ Upstream commit
d944eafed618a8507270b324ad9d5405bb7f0b3e ]
The skl+ scalers only sample 12 bits of PIPESRC so we can't
do any plane scaling at all when the pipe source size is >4k.
Make sure the pipe source size is also below the scaler's src
size limits. Might not be 100% accurate, but should at least be
safe. We can refine the limits later if we discover that recent
hw is less restricted.

wifi: rtw88: rtw8821c: Fix rfe_option field width
[ Upstream commit
14705f969d98187a1cc2682e0c9bd2e230b8098f ]
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.

drm/msm: Hangcheck progress detection
[ Upstream commit

If the hangcheck timer expires, check if the fw's position in the
cmdstream has advanced (changed) since last timer expiration, and
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)
v4: Comment updates to better describe the total hangcheck
duration when progress detection is applied

drm/msm/adreno: adreno_gpu: Use suspend() instead of idle() on load error
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).

HID: wacom: insert timestamp to packed Bluetooth (BT) events

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.

drm/amd/pm: avoid potential UBSAN issue on legacy asics
commit
5247f05eadf1081a74b2233f291cee2efed25e3a upstream.
Prevent further dpm casting on legacy asics without od_enabled in
amdgpu_dpm_is_overdrive_supported. This can avoid UBSAN complain
in init sequence.
v2: add a macro to check legacy dpm instead of checking asic family/type
v3: refine macro name for naming consistency

drm/amdgpu: disable sdma ecc irq only when sdma RAS is enabled in suspend
commit
8b229ada2669b74fdae06c83fbfda5a5a99fc253 upstream.
sdma_v4_0_ip is shared on a few asics, but in sdma_v4_0_hw_fini,
driver unconditionally disables ecc_irq which is only enabled on
those asics enabling sdma ecc. This will introduce a warning in
suspend cycle on those chips with sdma ip v4.0, while without
sdma ecc. So this patch correct this.

commit

[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

Currently, on a handful of ASICs. We allow the framebuffer for a given
plane to exist in either VRAM or GTT. However, if the plane's new
framebuffer is in a different memory domain than it's previous
framebuffer, flipping between them can cause the screen to flicker. So,
to fix this, don't perform an immediate flip in the aforementioned case.

drm/amd/display: Fix 4to1 MPC black screen with DPP RCO
commit
bf224e00a9f54e2bf14b4d720a09c3d2f4aa4aa8 upstream.
[Why]
DPP Root clock optimization when combined with 4to1 MPC combine results
in the screen turning black.
This is because the DPPCLK is stopped during the middle of an
optimize_bandwidth sequence during commit_minimal_transition without
going through plane power down/power up.
[How]
The intent of a 0Hz DPP clock through update_clocks is to disable the
DTO. This differs from the behavior of stopping the DPPCLK entirely
(utilizing a 0Hz clock on some ASIC) so it's better to move this logic
to reside next to plane power up/power down where we gate the HUBP/DPP
DOMAIN.
The new sequence should be:
Power down: PG enabled -> RCO on
Power up: RCO off -> PG disabled
Rename power_on_plane to power_on_plane_resources to reflect the
actual operation that's occurring.

drm/panel: otm8009a: Set backlight parent to panel device
commit
ab4f869fba6119997f7630d600049762a2b014fa upstream.
This is the logical place to put the backlight device, and it also
fixes a kernel crash if the MIPI host is removed. Previously the
backlight device would be unregistered twice when this happened - once
as a child of the MIPI host through `mipi_dsi_host_unregister`, and
once when the panel device is destroyed.

irqchip/loongson-eiointc: Fix returned value on parsing MADT
commit
112eaa8fec5ea75f1be003ec55760b09a86799f8 upstream.
In pch_pic_parse_madt(), a NULL parent pointer will be
returned from acpi_get_vec_parent() for second pch-pic domain
related to second bridge while calling eiointc_acpi_init() at
first time, where the parent of it has not been initialized
yet, and will be initialized during second time calling
eiointc_acpi_init(). So, it's reasonable to return zero so
that failure of acpi_table_parse_madt() will be avoided, or else
acpi_cascade_irqdomain_init() will return and initialization of
followed pch_msi domain will be skipped.
Although it does not matter when pch_msi_parse_madt() returns
-EINVAL if no invalid parent is found, it's also reasonable to
return zero for that.

irqchip/loongson-pch-pic: Fix pch_pic_acpi_init calling
commit
48ce2d722f7f108f27bedddf54bee3423a57ce57 upstream.
For dual-bridges scenario, pch_pic_acpi_init() will be called
in following path:
cpuintc_acpi_init
acpi_cascade_irqdomain_init(in cpuintc driver)
acpi_table_parse_madt
eiointc_parse_madt
eiointc_acpi_init /* this will be called two times
correspondingto parsing two
eiointc entries in MADT under
dual-bridges scenario*/
acpi_cascade_irqdomain_init(in eiointc driver)
acpi_table_parse_madt
pch_pic_parse_madt
pch_pic_acpi_init /* this will be called depend
on valid parent IRQ domain
handle for one or two times
corresponding to parsing
two pchpic entries in MADT
druring calling
eiointc_acpi_init() under
dual-bridges scenario*/
During the first eiointc_acpi_init() calling, the
pch_pic_acpi_init() will be called just one time since only
one valid parent IRQ domain handle will be found for current
eiointc IRQ domain.
During the second eiointc_acpi_init() calling, the
pch_pic_acpi_init() will be called two times since two valid
parent IRQ domain handles will be found. So in pch_pic_acpi_init(),
we must have a reasonable way to prevent from creating second same
pch_pic IRQ domain.
The patch matches gsi base information in created pch_pic IRQ
domains to check if the target domain has been created to avoid the
bug mentioned above.

drm/i915/dsi: Use unconditional msleep() instead of intel_dsi_msleep()
commit
c8c2969bfcba5fcba3a5b078315c1b586d927d9f upstream.
The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have
a version of 3 or newer and the panel is in vid-mode.
This is based on the big comment around line 730 which starts with
"Panel enable/disable sequences from the VBT spec.", where
the "v3 video mode seq" column does not have any wait t# entries.
Checking the Windows driver shows that it does always honor
the VBT delays independent of the version of the VBT sequences.
Commit
6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for
the panel_on_delay when there is no reset-deassert MIPI-sequence")
switched to a direct msleep() instead of intel_dsi_msleep()
when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix
the panel on an Acer Aspire Switch 10 E SW3-016 not turning on.
And now testing on a Nextbook Ares 8A shows that panel_on_delay
must always be honored otherwise the panel will not turn on.
Instead of only always using regular msleep() for panel_on_delay
do as Windows does and always use regular msleep() everywhere
were intel_dsi_msleep() is used and drop the intel_dsi_msleep()
helper.
Changes in v2:
- Replace all intel_dsi_msleep() calls instead of just
the intel_dsi_msleep(panel_on_delay) call

A recent commit moved enabling of runtime PM to GPU load time (first

disabled if initialisation of the GPU fails. This would trigger a
warning about the unbalanced disable count on the next open() attempt.
Note that pm_runtime_put_noidle() is sufficient to balance the usage
count when pm_runtime_put_sync() fails (and is chosen over
pm_runtime_resume_and_get() for consistency reasons).

remoteproc: imx_dsp_rproc: Call of_node_put() on iteration error
commit
e0e01de8ee146986872e54e8365f4b4654819412 upstream.
Function of_phandle_iterator_next() calls of_node_put() on the last
device_node it iterated over, but when the loop exits prematurely it has
to be called explicitly.

proc_sysctl: enhance documentation
commit
1dc8689e4cc651e21566e10206a84c4006e81fb1 upstream.
Expand documentation to clarify:
o that paths don't need to exist for the new API callers
o clarify that we *require* callers to keep the memory of
the table around during the lifetime of the sysctls
o annotate routines we are trying to deprecate and later remove
