2026-02-03drm/amd: kill the outdated "Only the pthreads threading model is supported" ↵Oleg Nesterov
checks Nowadays task->group_leader->mm != task->mm is only possible if a) task is not a group leader and b) task->group_leader->mm == NULL because task->group_leader has already exited using sys_exit(). I don't think that drm/amd tries to detect/nack this case.

2026-01-29drm/amdgpu: Add a helper macro to align mqd sizeLang Yu
MES FW uses address(mqd_addr + sizeof(struct mqd) + 3*sizeof(uint32_t)) as fence address and writes a 32 bit fence value to this address. Driver needs to allocate some extra memory(at least 4 DWs) in addition to sizeof(struct mqd) as mqd memory(limited to gfx/compute/sdma queue). For gfx11/12, sizeof(struct mqd) < PAGE_SIZE, KGD allocates mqd memory with PAGE_SIZE aligned works. For gfx12.1, sizeof(struct mqd) == PAGE_SIZE, it doesn't work. KFD mqd manager hardcodes mqd size to PAGE_SIZE/MQD_SIZE across different IP versions to solve this issue. To avoid hardcoding in differnet places and across different IP versions. Let's use AMDGPU_MQD_SIZE_ALIGN instead. It is used in two places. 1. mqd memory alloction 2. mqd stride handling for multi xcc config v2: Use AMDGPU_GPU_PAGE_ALIGN.

2026-01-27drm/amdgpu: fix NULL pointer dereference in amdgpu_gmc_filter_faults_removeJon Doron
On APUs such as Raven and Renoir (GC 9.1.0, 9.2.2, 9.3.0), the ih1 and ih2 interrupt ring buffers are not initialized. This is by design, as these secondary IH rings are only available on discrete GPUs. See vega10_ih_sw_init() which explicitly skips ih1/ih2 initialization when AMD_IS_APU is set. However, amdgpu_gmc_filter_faults_remove() unconditionally uses ih1 to get the timestamp of the last interrupt entry. When retry faults are enabled on APUs (noretry=0), this function is called from the SVM page fault recovery path, resulting in a NULL pointer dereference when amdgpu_ih_decode_iv_ts_helper() attempts to access ih->ring[]. The crash manifests as: BUG: kernel NULL pointer dereference, address: 0000000000000004 RIP: 0010:amdgpu_ih_decode_iv_ts_helper+0x22/0x40 [amdgpu] Call Trace: amdgpu_gmc_filter_faults_remove+0x60/0x130 [amdgpu] svm_range_restore_pages+0xae5/0x11c0 [amdgpu] amdgpu_vm_handle_fault+0xc8/0x340 [amdgpu] gmc_v9_0_process_interrupt+0x191/0x220 [amdgpu] amdgpu_irq_dispatch+0xed/0x2c0 [amdgpu] amdgpu_ih_process+0x84/0x100 [amdgpu] This issue was exposed by commit 1446226d32a4 ("drm/amdgpu: Remove GC HW IP 9.3.0 from noretry=1") which changed the default for Renoir APU from noretry=1 to noretry=0, enabling retry fault handling and thus exercising the buggy code path. Fix this by adding a check for ih1.ring_size before attempting to use it. Also restore the soft_ih support from commit dd299441654f ("drm/amdgpu: Rework retry fault removal"). This is needed if the hardware doesn't support secondary HW IH rings. v2: additional updates (Alex) Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3814 Fixes: dd299441654f ("drm/amdgpu: Rework retry fault removal") Reviewed-by: Timur Kristóf <timur.kristof@gmail.com> Reviewed-by: Philip Yang <Philip.Yang@amd.com> Signed-off-by: Jon Doron <jond@wiz.io> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit 6ce8d536c80aa1f059e82184f0d1994436b1d526) Cc: stable@vger.kernel.org

2026-01-27drm/amd/pm: fix race in power state check before mutex lockYang Wang
The power state check in amdgpu_dpm_set_powergating_by_smu() is done before acquiring the pm mutex, leading to a race condition where: 1. Thread A checks state and thinks no change is needed 2. Thread B acquires mutex and modifies the state 3. Thread A returns without updating state, causing inconsistency Fix this by moving the mutex lock before the power state check, ensuring atomicity of the state check and modification.

2026-01-27drm/amd/display: avoid dig reg access timeout on usb4 link training failZhongwei
[Why] When usb4 link training fails, the dpia sym clock will be disabled and SYMCLK source should be changed back to phy clock. In enable_streams, it is assumed that link training succeeded and will switch from refclk to phy clock. But phy clk here might not be on. Dig reg access timeout will occur. [How] When enable_stream is hit, check if link training failed for usb4. If it did, fall back to the ref clock to avoid reg access timeout.
