[PATCH AUTOSEL 6.16] gpiolib: acpi: Add quirk for ASUS ProArt PX13

by Sasha Levin

From: "Mario Limonciello (AMD)" <superm1(a)kernel.org> [ Upstream commit 23800ad1265f10c2bc6f42154ce4d20e59f2900e ] The ASUS ProArt PX13 has a spurious wakeup event from the touchpad a few moments after entering hardware sleep. This can be avoided by preventing the touchpad from being a wake source. Add to the wakeup ignore list. Reported-by: Amit Chaudhari <amitchaudhari(a)mac.com> Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4482 Tested-by: Amit Chaudhari <amitchaudhari(a)mac.com> Signed-off-by: Mario Limonciello (AMD) <superm1(a)kernel.org> Reviewed-by: Mika Westerberg <mika.westerberg(a)linux.intel.com> Link: https://lore.kernel.org/20250814183430.3887973-1-superm1@kernel.org Signed-off-by: Linus Walleij <linus.walleij(a)linaro.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- LLM Generated explanations, may be completely bogus: Based on my comprehensive analysis of this commit and the context, here is my assessment: **Backport Status: YES** ## Extensive Analysis: ### 1. **Nature of the Fix** This commit fixes a real hardware bug - spurious wakeup events from the touchpad on the ASUS ProArt PX13 laptop. The code change adds a DMI- based quirk entry to the `gpiolib_acpi_quirks` table in `/home/sasha/linux/drivers/gpio/gpiolib-acpi-quirks.c:350-359`, which instructs the GPIO subsystem to ignore wake events from the specific touchpad GPIO pin (`ASCP1A00:00@8`). ### 2. **符合稳定内核规则 (Meets Stable Kernel Rules)** According to `/home/sasha/linux/Documentation/process/stable-kernel- rules.rst`: - **Fixes a real bug**: Yes - spurious wakeups are a real hardware issue that impacts users' ability to use sleep/suspend effectively (lines 18-19 of rules) - **Obviously correct and tested**: Yes - the fix is straightforward (adding a quirk entry), has been tested by the reporter (Amit Chaudhari), and reviewed by Mika Westerberg - **Size constraint**: The patch is only ~20 lines with context, well under the 100-line limit - **Already in mainline**: Yes - commit 23800ad1265f10c2bc6f42154ce4d20e59f2900e ### 3. **Historical Precedent** Multiple similar commits for spurious wakeup quirks have been backported to stable: - Commit `805c74eac8cb3` (GPD G1619-04 touchpad wakeup) - explicitly marked with `Cc: stable(a)vger.kernel.org` - Commit `782eea0c89f7d` (Clevo NL5xNU) - marked with `Cc: stable(a)vger.kernel.org` - Commit `a69982c37cd05` (Clevo NH5xAx) - marked with `Cc: <stable(a)vger.kernel.org> # v6.1+` ### 4. **Code Structure Analysis** The change follows the exact same pattern as other quirk entries in the file: ```c .driver_data = &(struct acpi_gpiolib_dmi_quirk) { .ignore_wake = "ASCP1A00:00@8", }, ``` This is a data-only addition to an existing quirk table - no logic changes, no new code paths, minimal regression risk. ### 5. **User Impact** The bug causes spurious wakeups "a few moments after entering hardware sleep", which: - Prevents proper system suspend/sleep functionality - Drains battery life on laptops - Disrupts user workflow - Is a clear hardware-specific issue that cannot be worked around by users ### 6. **Risk Assessment** - **Extremely low risk**: The change only affects systems that match the specific DMI strings (ASUSTeK COMPUTER INC. + ProArt PX13) - **No impact on other systems**: DMI matching ensures this quirk only applies to the affected hardware - **Well-established mechanism**: The ignore_wake infrastructure is mature and widely used ### 7. **Backporting Considerations** While this specific commit wasn't explicitly marked with `Cc: stable`, it follows the exact same pattern as commits that were. The commit has already been picked up by Sasha Levin's stable tree (as shown in the `[ Upstream commit ]` tag in the local repository), suggesting the stable maintainers recognize its importance. The fix is self-contained, requires no prerequisites, and can be cleanly applied to any kernel version that has the `gpiolib-acpi-quirks.c` file structure (introduced in commit `92dc572852ddc`). ### Conclusion This is a textbook example of a stable-appropriate fix: it addresses a specific hardware bug affecting real users, uses a well-established quirk mechanism, has zero impact on unaffected systems, and follows the exact pattern of previously backported fixes for identical issues on different hardware. drivers/gpio/gpiolib-acpi-quirks.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/drivers/gpio/gpiolib-acpi-quirks.c b/drivers/gpio/gpiolib-acpi-quirks.c index c13545dce3492..bfb04e67c4bc8 100644 --- a/drivers/gpio/gpiolib-acpi-quirks.c +++ b/drivers/gpio/gpiolib-acpi-quirks.c @@ -344,6 +344,20 @@ static const struct dmi_system_id gpiolib_acpi_quirks[] __initconst = { .ignore_interrupt = "AMDI0030:00@8", }, }, + { + /* + * Spurious wakeups from TP_ATTN# pin + * Found in BIOS 5.35 + * https://gitlab.freedesktop.org/drm/amd/-/issues/4482 + */ + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."), + DMI_MATCH(DMI_PRODUCT_FAMILY, "ProArt PX13"), + }, + .driver_data = &(struct acpi_gpiolib_dmi_quirk) { + .ignore_wake = "ASCP1A00:00@8", + }, + }, {} /* Terminating entry */ }; -- 2.50.1

[PATCH] blk-throttle: check policy bit in blk_throtl_activated()

by gj.han＠foxmail.com

From: Han Guangjiang <hanguangjiang(a)lixiang.com> On repeated cold boots we occasionally hit a NULL pointer crash in blk_should_throtl() when throttling is consulted before the throttle policy is fully enabled for the queue. Checking only q->td != NULL is insufficient during early initialization, so blkg_to_pd() for the throttle policy can still return NULL and blkg_to_tg() becomes NULL, which later gets dereferenced. Tighten blk_throtl_activated() to also require that the throttle policy bit is set on the queue: return q->td != NULL && test_bit(blkcg_policy_throtl.plid, q->blkcg_pols); This prevents blk_should_throtl() from accessing throttle group state until policy data has been attached to blkgs.

[PATCH v2 1/3] drm/xe: Attempt to bring bos back to VRAM after eviction

by Thomas Hellström

VRAM+TT bos that are evicted from VRAM to TT may remain in TT also after a revalidation following eviction or suspend. This manifests itself as applications becoming sluggish after buffer objects get evicted or after a resume from suspend or hibernation. If the bo supports placement in both VRAM and TT, and we are on DGFX, mark the TT placement as fallback. This means that it is tried only after VRAM + eviction. This flaw has probably been present since the xe module was upstreamed but use a Fixes: commit below where backporting is likely to be simple.

Can you show the stack trace leading to this function being called from an arbitrary provider (like a packet being fed by malicious user space) For instance nr_rx_frame() can be called from net/netrom/nr_loopback.c with non malicious packet. For the remaining caller (nr_route_frame()), it is unclear to me.

[PATCH 3/3] xhci: fix memory leak regression when freeing xhci vdev devices depth first

by Mathias Nyman

Suspend-resume cycle test revealed a memory leak in 6.17-rc3 Turns out the slot_id race fix changes accidentally ends up calling xhci_free_virt_device() with an incorrect vdev parameter. The vdev variable was reused for temporary purposes right before calling xhci_free_virt_device(). Fix this by passing the correct vdev parameter. The slot_id race fix that caused this regression was targeted for stable, so this needs to be applied there as well.

[PATCH 2/3] xhci: dbc: Fix full DbC transfer ring after several reconnects

by Mathias Nyman

Pending requests will be flushed on disconnect, and the corresponding TRBs will be turned into No-op TRBs, which are ignored by the xHC controller once it starts processing the ring. If the USB debug cable repeatedly disconnects before ring is started then the ring will eventually be filled with No-op TRBs. No new transfers can be queued when the ring is full, and driver will print the following error message: "xhci_hcd 0000:00:14.0: failed to queue trbs" This is a normal case for 'in' transfers where TRBs are always enqueued in advance, ready to take on incoming data. If no data arrives, and device is disconnected, then ring dequeue will remain at beginning of the ring while enqueue points to first free TRB after last cancelled No-op TRB. s Solve this by reinitializing the rings when the debug cable disconnects and DbC is leaving the configured state. Clear the whole ring buffer and set enqueue and dequeue to the beginning of ring, and set cycle bit to its initial state.

[PATCH 1/3] xhci: dbc: decouple endpoint allocation from initialization

Decouple allocation of endpoint ring buffer from initialization of the buffer, and initialization of endpoint context parts from from the rest of the contexts. It allows driver to clear up and reinitialize endpoint rings after disconnect without reallocating everything. This is a prerequisite for the next patch that prevents the transfer ring from filling up with cancelled (no-op) TRBs if a debug cable is reconnected several times without transferring anything.
