2025-08-29drm/xe: Fix incorrect migration of backed-up object to VRAMThomas Hellström
If an object is backed up to shmem it is incorrectly identified as not having valid data by the move code. This means moving to VRAM skips the -EMULTIHOP step and the bo is cleared. This causes all sorts of weird behaviour on DGFX if an already evicted object is targeted by the shrinker. Fix this by using ttm_tt_is_swapped() to identify backed-up objects.

2025-08-29drm/v3d: Protect per-fd reset counter against fd releaseMaíra Canal
The per-fd reset counter tracks GPU resets caused by jobs submitted through a specific file descriptor. However, there's a race condition where the file descriptor can be closed while jobs are still running, leading to potential access to freed memory when updating the reset counter. Ensure that the per-fd reset counter is only updated when the file descriptor is still valid, preventing use-after-free scenarios during GPU reset handling.

2025-08-29drm/v3d: Address race-condition between per-fd GPU stats and fd releaseMaíra Canal

2025-08-29drm/v3d: Replace a global spinlock with a per-queue spinlockMaíra Canal
Each V3D queue works independently and all the dependencies between the jobs are handled through the DRM scheduler. Therefore, there is no need to use one single lock for all queues. Using it, creates unnecessary contention between different queues that can operate independently. Replace the global spinlock with per-queue locks to improve parallelism and reduce contention between different V3D queues (BIN, RENDER, TFU, CSD). This allows independent queues to operate concurrently while maintaining proper synchronization within each queue.

2025-08-29spi: microchip-core-qspi: stop checking viability of op->max_freq in ↵Conor Dooley
supports_op callback In commit 13529647743d9 ("spi: microchip-core-qspi: Support per spi-mem operation frequency switches") the logic for checking the viability of op->max_freq in mchp_coreqspi_setup_clock() was copied into mchp_coreqspi_supports_op(). Unfortunately, op->max_freq is not valid when this function is called during probe but is instead zero. Accordingly, baud_rate_val is calculated to be INT_MAX due to division by zero, causing probe of the attached memory device to fail. Seemingly spi-microchip-core-qspi was the only driver that had such a modification made to its supports_op callback when the per_op_freq capability was added, so just remove it to restore prior functionality.

Since commit ad67b74d2469 ("printk: hash addresses printed with %p") the regular %p has been improved to avoid this issue. Furthermore, restricted pointers ("%pK") were never meant to be used through printk(). They can still unintentionally leak raw pointers or acquire sleeping locks in atomic contexts.

2025-08-29drivers: firmware: xilinx: Switch to new family code in ↵Jay Buddhabhatti
zynqmp_pm_get_family_info() Currently, the family code and subfamily code are derived from the PMC_TAP_IDCODE register. Versal, Versal NET share the same family code. Also some platforms share the same subfamily code, making it difficult to distinguish between platforms. Update zynqmp_pm_get_family_info() to use IDs derived from the compatible string instead of silicon ID codes derived from PMC_TAP_IDCODE register.

2025-08-29drivers: firmware: xilinx: Add unique family code for all platformsJay Buddhabhatti
The family code is currently derived from the PMC_TAP_IDCODE register value, but there are issues where Versal, Versal NET, and future platforms share the same family code. Additionally for some platforms have identical subfamily code, making it challenging to differentiate between platforms based on the family and subfamily codes. To resolve this, a new family code member is added to the platform data, initialized with unique values. This change enables better platform distinction via the compatible string.

Then move virtchnl files into a new subdir. No logic changes. I have developed (or discovered ;)) how to split a file in a way that both old and new are nice in terms of git-blame There was not much discussion on [RFC], so I would like to propose to go forward with this approach. There are more commits needed to have it nice, so it forms a git-log vs git-blame tradeoff, but (after the brief moment that this is on the top) we spend orders of magnitude more time looking at the blame output (and commit messages linked from that) - so I find it much better to see actual logic changes instead of "move xx to yy" stuff (typical for "squashed/single-commit splits"). Cherry-picks/rebases work the same with this method as with simple "squashed/single-commit" approach (literally all commits squashed into one (to have better git-log, but shitty git-blame output). Rationale for the split itself is, as usual, "file is big and we want to extend it". * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: finish virtchnl.c split into rss.c ice: extract virt/rss.c: cleanup - p2 ice: extract virt/rss.c: cleanup - p1 ice: split RSS stuff out of virtchnl.c - copy back ice: split RSS stuff out of virtchnl.c - tmp rename ice: finish virtchnl.c split into queues.c ice: extract virt/queues.c: cleanup - p3 ice: extract virt/queues.c: cleanup - p2 ice: extract virt/queues.c: cleanup - p1 ice: split queue stuff out of virtchnl.c - copy back ice: split queue stuff out of virtchnl.c - tmp rename ice: add virt/ and move ice_virtchnl* files there ==================== Link: https://patch.msgid.link/20250827224641.415806-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-08-28eth: mlx5: remove Kconfig co-dependency with VXLANJakub Kicinski
mlx5 has a Kconfig co-dependency on VXLAN, even tho it doesn't call any VXLAN function (unlike mlxsw). Perhaps this dates back to very old days when tunnel ports were fetched directly from VXLAN. Remove the dependency to allow MLX5=y + VXLAN=m kernel configs. But still avoid compiling in the lib/vxlan code if VXLAN=n.

The C45 accessors were setting the GR (register number) field twice, once with the 16-bit register address truncated to five bits, and then overwritten with the C45 devad. This is harmless since the field was being cleared prior to being updated with the C45 devad, except for the extra work. Remove the redundant code.
