2025-07-04drm/imagination: Fix kernel crash when hard resetting the GPUAlessio Belle
The GPU hard reset sequence calls pm_runtime_force_suspend() and pm_runtime_force_resume(), which according to their documentation should only be used during system-wide PM transitions to sleep states. The main issue though is that depending on some internal runtime PM state as seen by pm_runtime_force_suspend() (whether the usage count is <= 1), pm_runtime_force_resume() might not resume the device unless needed. If that happens, the runtime PM resume callback pvr_power_device_resume() is not called, the GPU clocks are not re-enabled, and the kernel crashes on the next attempt to access GPU registers as part of the power-on sequence. Replace calls to pm_runtime_force_suspend() and pm_runtime_force_resume() with direct calls to the driver's runtime PM callbacks, pvr_power_device_suspend() and pvr_power_device_resume(), to ensure clocks are re-enabled and avoid the kernel crash.

2025-07-04iommu/vt-d: Assign devtlb cache tag on ATS enablementLu Baolu
Commit <4f1492efb495> ("iommu/vt-d: Revert ATS timing change to fix boot failure") placed the enabling of ATS in the probe_finalize callback. This occurs after the default domain attachment, which is when the ATS cache tag is assigned. Consequently, the device TLB cache tag is missed when the domain is attached, leading to the device TLB not being invalidated in the iommu_unmap paths. Fix this by assigning the CACHE_TAG_DEVTLB cache tag when ATS is enabled.

2025-07-04gpiolib: fix performance regression when using gpio_chip_get_multiple()Hugo Villeneuve
commit 74abd086d2ee ("gpiolib: sanitize the return value of gpio_chip::get_multiple()") altered the value returned by gc->get_multiple() in case it is positive (> 0), but failed to return for other cases (<= 0). This may result in the "if (gc->get)" block being executed and thus negates the performance gain that is normally obtained by using gc->get_multiple(). Fix by returning the result of gc->get_multiple() if it is <= 0. Also move the "ret" variable to the scope where it is used, which as an added bonus fixes an indentation error introduced by the aforementioned commit.

Switch from %pK to %p for pointer formatting, as %p is now safer and prevents issues like raw pointer leakage and acquiring sleeping locks in atomic contexts. - Fixed kernel panic during boot . A NULL pointer dereference issue occasionally occurred when the vblank interrupt handler was called before the DRM driver was fully initialized during boot. So this patch fixes the issue by adding a check in the interrupt handler to ensure the DRM driver is properly initialized. - Fixed a lockup issue on Samsung Peach-Pit/Pi Chromebooks . The issue occurred after commit c9b1150a68d9 changed the call order of CRTC enable/disable and bridge pre_enable/post_disable methods, causing fimd_dp_clock_enable() to be called before the FIMD device was activated. To fix this, runtime PM guards were added to fimd_dp_clock_enable() to ensure proper operation even when CRTC is not enabled.

2025-07-04pinctrl: amd: Clear GPIO debounce for suspendMario Limonciello
soc-button-array hardcodes a debounce value by means of gpio_keys which uses pinctrl-amd as a backend to program debounce for a GPIO. This hardcoded value doesn't match what the firmware intended to be programmed in _AEI. The hardcoded debounce leads to problems waking from suspend. There isn't appetite to conditionalize the behavior in soc-button-array or gpio-keys so clear it when the system suspends to avoid problems with being able to resume.

This fixes a bunch of command hangs after runtime suspend/resume. This fixes a regression caused by code movement in the commit below, the commit seems to just change timings enough to cause this to happen now, and adding the sleep seems to avoid it. I've spent some time trying to root cause it to no great avail, it seems like a bug on the firmware side, but it could be a bug in our rpc handling that I can't find. Either way, we should land the workaround to fix the problem, while we continue to work out the root cause.

2025-07-03drm/nouveau: Do not fail module init on debugfs errorsAaron Thompson
If CONFIG_DEBUG_FS is enabled, nouveau_drm_init() returns an error if it fails to create the "nouveau" directory in debugfs. One case where that will happen is when debugfs access is restricted by CONFIG_DEBUG_FS_ALLOW_NONE or by the boot parameter debugfs=off, which cause the debugfs APIs to return -EPERM. So just ignore errors from debugfs. Note that nouveau_debugfs_root may be an error now, but that is a standard pattern for debugfs. From include/linux/debugfs.h: "NOTE: it's expected that most callers should _ignore_ the errors returned by this function. Other debugfs functions handle the fact that the "dentry" passed to them could be an error and they don't crash in that case. Drivers should generally work fine even if debugfs fails to init anyway."

2025-07-03net: ngbe: specify IRQ vector when the number of VFs is 7Jiawen Wu
For NGBE devices, the queue number is limited to be 1 when SRIOV is enabled. In this case, IRQ vector[0] is used for MISC and vector[1] is used for queue, based on the previous patches. But for the hardware design, the IRQ vector[1] must be allocated for use by the VF[6] when the number of VFs is 7. So the IRQ vector[0] should be shared for PF MISC and QUEUE interrupts. +-----------+----------------------+ | Vector | Assigned To | +-----------+----------------------+ | Vector 0 | PF MISC and QUEUE | | Vector 1 | VF 6 | | Vector 2 | VF 5 | | Vector 3 | VF 4 | | Vector 4 | VF 3 | | Vector 5 | VF 2 | | Vector 6 | VF 1 | | Vector 7 | VF 0 | +-----------+----------------------+ Minimize code modifications, only adjust the IRQ vector number for this case.

Due to hardware limitations of NGBE, queue IRQs can only be requested on vector 0 to 7. When the number of queues is set to the maximum 8, the PCI IRQ vectors are allocated from 0 to 8. The vector 0 is used by MISC interrupt, and althrough the vector 8 is used by queue interrupt, it is unable to receive packets. This will cause some packets to be dropped when RSS is enabled and they are assigned to queue 8. So revert the adjustment of the MISC IRQ location, to make it be the last one in IRQ vectors.

2025-07-03virtio_net: Enforce minimum TX ring size for reliabilityLaurent Vivier
The `tx_may_stop()` logic stops TX queues if free descriptors (`sq->vq->num_free`) fall below the threshold of (`MAX_SKB_FRAGS` + 2). If the total ring size (`ring_num`) is not strictly greater than this value, queues can become persistently stopped or stop after minimal use, severely degrading performance. A single sk_buff transmission typically requires descriptors for: - The virtio_net_hdr (1 descriptor) - The sk_buff's linear data (head) (1 descriptor) - Paged fragments (up to MAX_SKB_FRAGS descriptors) This patch enforces that the TX ring size ('ring_num') must be strictly greater than (MAX_SKB_FRAGS + 2). This ensures that the ring is always large enough to hold at least one maximally-fragmented packet plus at least one additional slot.

The virtqueue_resize() function was not correctly propagating error codes from its internal resize helper functions, specifically virtqueue_resize_packet() and virtqueue_resize_split(). If these helpers returned an error, but the subsequent call to virtqueue_enable_after_reset() succeeded, the original error from the resize operation would be masked. Consequently, virtqueue_resize() could incorrectly report success to its caller despite an underlying resize failure.

2025-07-03HID: appletb-kbd: fix slab use-after-free bug in appletb_kbd_probeQasim Ijaz
In probe appletb_kbd_probe() a "struct appletb_kbd *kbd" is allocated via devm_kzalloc() to store touch bar keyboard related data. Later on if backlight_device_get_by_name() finds a backlight device with name "appletb_backlight" a timer (kbd->inactivity_timer) is setup with appletb_inactivity_timer() and the timer is armed to run after appletb_tb_dim_timeout (60) seconds. A use-after-free is triggered when failure occurs after the timer is armed. This ultimately means probe failure occurs and as a result the "struct appletb_kbd *kbd" which is device managed memory is freed. After 60 seconds the timer will have expired and __run_timers will attempt to access the timer (kbd->inactivity_timer) however the kdb structure has been freed causing a use-after free.

2025-07-03virtio-net: xsk: rx: fix the frame's length checkBui Quang Minh
When calling buf_to_xdp, the len argument is the frame data's length without virtio header's length (vi->hdr_len). We check that len with xsk_pool_get_rx_frame_size() + vi->hdr_len to ensure the provided len does not larger than the allocated chunk size. The additional vi->hdr_len is because in virtnet_add_recvbuf_xsk, we use part of XDP_PACKET_HEADROOM for virtio header and ask the vhost to start placing data from hard_start + XDP_PACKET_HEADROOM - vi->hdr_len not hard_start + XDP_PACKET_HEADROOM But the first buffer has virtio_header, so the maximum frame's length in the first buffer can only be xsk_pool_get_rx_frame_size() not xsk_pool_get_rx_frame_size() + vi->hdr_len like in the current check. This commit adds an additional argument to buf_to_xdp differentiate between the first buffer and other ones to correctly calculate the maximum frame's length.

2025-07-03HID: appletb-kbd: fix memory corruption of input_handler_listQasim Ijaz
In appletb_kbd_probe an input handler is initialised and then registered with input core through input_register_handler(). When this happens input core will add the input handler (specifically its node) to the global input_handler_list. The input_handler_list is central to the functionality of input core and is traversed in various places in input core. An example of this is when a new input device is plugged in and gets registered with input core. The input_handler in probe is allocated as device managed memory. If a probe failure occurs after input_register_handler() the input_handler memory is freed, yet it will remain in the input_handler_list. This effectively means the input_handler_list contains a dangling pointer to data belonging to a freed input handler. This causes an issue when any other input device is plugged in - in my case I had an old PixArt HP USB optical mouse and I decided to plug it in after a failure occurred after input_register_handler(). This lead to the registration of this input device via input_register_device which involves traversing over every handler in the corrupted input_handler_list and calling input_attach_handler(), giving each handler a chance to bind to newly registered device. The core of this bug is a UAF which causes memory corruption of input_handler_list and to fix it we must ensure the input handler is unregistered from input core, this is done through input_unregister_handler().

When setting "ethtool -L eth0 combined 1", the number of RX/TX queue is changed to be 1. RSS is disabled at this moment, and the indices of FDIR have not be changed in wx_set_rss_queues(). So the combined count still shows the previous value. This issue was introduced when supporting FDIR. Fix it for those devices that support FDIR.
