5 daysdrm/amdgpu: nuke amdgpu_userq_fence_slab v2Christian König
As preparation for independent fences remove the extra slab, kmalloc should do just fine. v2: use GFP_KERNEL instead of GFP_ATOMIC Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Prike Liang <Prike.Liang@amd.com> Reviewed-by: Sunil Khatri <sunil.khatri@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit 0d831487b5be0ae59cac865a0aa87b0acc3dc717)
5 daysdrm/amdgpu/userq: fix access to stale wptr mappingSunil Khatri
Use drm_exec to take both locks i.e vm root bo and wptr_obj bo to access the mapping data properly. This fixes the security issue of unmap the wptr_obj while a queue creation is in progress and passing other bo at same address.

5 daysdrm/amdkfd: Check if there are kfd porcesses using adev by kfd_processes_countXiaogang Chen
During gpu hot-unplug need check if there are kfd porcesses still using the being removed gpu before clean resources of the device. Current driver checks if kfd_processes_table is empty. kfd processes are not terminated after removed from kfd_processes_table immediately. They are still alive and may access the device until kfd_process_wq work queue got ran. Check kfd->kfd_processes_count value that is updated after kfd process got uninitialized when its ref becomes zero.

5 daysdrm/amdgpu: zero-initialize GART table on allocationPhilip Yang
GART TLB is flushed after unmapping but not after mapping. Since amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a single PTE is written the TLB may speculatively load other uninitialized entries from the same cacheline. Those garbage entries can appear valid, and a subsequent write to another PTE in the same cacheline may cause the GPU to use a stale garbage PTE from the TLB. Fix this by calling memset_io() to zero-initialize the GART table with gart_pte_flags immediately after allocation. Using AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will not work since SDMA needs GART to be initialized to work.

5 daysdrm/amdgpu/sdma4: replace BUG_ON with WARN_ON in fence emissionJohn B. Moore
sdma_v4_0_ring_emit_fence() contains two BUG_ON(addr & 0x3) assertions that verify fence writeback addresses are dword-aligned. These assertions can be reached from unprivileged userspace via crafted DRM_IOCTL_AMDGPU_CS submissions, causing a fatal kernel panic in a scheduler worker thread. Replace both BUG_ON() calls with WARN_ON() to log the condition without crashing the kernel. A misaligned fence address at this point indicates a driver bug, but crashing the kernel is never the correct response when the assertion is reachable from userspace. The CS IOCTL path is the correct place to filter invalid submissions; the ring emission callback is too late to do anything about it.

Remove the BUG_ON(flags & AMDGPU_FENCE_FLAG_64BIT) assertion from gfx_v9_0_ring_emit_fence_kiq(). The KIQ hardware supports 64-bit fence writes; the 32-bit writeback address constraint is an upper-layer convention, not a hardware limitation. The check serves no purpose and should not be present.

12 daysdrm/amd/display: Update MCIF_ADDR macro to address IGT DWB regressionGaghik Khachatrian
[Why] A previous warning-fix commit updated type casts in the DCN3 mmhubbub code but missed updating the MCIF_ADDR macro to the correct, fully parenthesized and casted version. This caused a regression during DWB tests, where address values could be misinterpreted, potentially leading to incorrect hardware programming. [How] Updated the MCIF_ADDR macro in dcn30_mmhubbub.c to use the proper parenthesization and type casting, ensuring correct address handling. Removed redundant casts from REG_UPDATE calls for improved clarity and consistency with current coding standards.
