10 daysdrm/amdgpu: Fix double deletion of validate_listHarish Kasiviswanathan
If amdgpu_amdkfd_gpuvm_free_memory_of_gpu() fails after kgd_mem is removed from validate_list, the mem handle still lingers in the KFD idr. This means when process is terminated, kfd_process_free_outstanding_kfd_bos() will call amdgpu_amdkfd_gpuvm_free_memory_of_gpu() again resulting in double deletion. To avoid this - (a) Check if list is empty before deleting it (b) Rearragne amdgpu_amdkfd_gpuvm_free_memory_of_gpu() such that it can be safely called again if it returns failure the first time.

This commit was erroneously applied again after commit 0ab5d711ec74 ("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device") removed it, leading to very hard to debug crashes, when used with a system with two AMD GPUs of which only one supports ASPM.

commit f81cd793119e ("drm/amd/amdgpu: Fix MES init sequence") caused a dependency on new enough MES firmware to use amdgpu. This was fixed on most gfx11 and gfx12 hardware with commit 0180e0a5dd5c ("drm/amdgpu/mes: add compatibility checks for set_hw_resource_1"), but this left out that GC 11.0.4 had breakage at MES 0x51.

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").

2026-01-27drm/amdgpu: Send RMA CPER at bad page loadingKent Russell
Some older builds weren't sending RMA CPERs when the bad page threshold was exceeded. Newer builds have resolved this, but there could be systems out there with bad page numbers higher than the threshold, that haven't sent out an RMA CPER. To be thorough and safe, send an RMA CPER when we load the table, if the threshold is met or exceeded, instead of waiting for the next UE to trigger the CPER.

There is also interrupt handling code in SDMA 5.0 and 5.2 which appears to be using it, but is is unreachable since nothing ever allocates the relevant IDR.
