drm/amdgpu: fix cyan_skillfish2 gpu info fw handling

2025-11-26T17:34:16Z

If the board supports IP discovery, we don't need to parse the gpu info firmware. Backport to 6.18.

drm/amdgpu: attach tlb fence to the PTs update

2025-11-26T17:33:05Z

Ensure the userq TLB flush is emitted only after the VM update finishes and the PT BOs have been annotated with bookkeeping fences.

drm/amdgpu/ttm: Fix crash when handling MMIO_REMAP in PDE flags

2025-11-19T23:08:37Z

The MMIO_REMAP BO is a special 4K IO page that does not have a ttm_tt behind it. However, amdgpu_ttm_tt_pde_flags() was treating it like normal TT/doorbell/preempt memory and unconditionally accessed ttm->caching. For the MMIO_REMAP BO, ttm is NULL, so this leads to a NULL pointer dereference when computing PDE flags. Fix this by checking that ttm is non-NULL before reading ttm->caching. This prevents the crash for MMIO_REMAP and also makes the code more defensive if other BOs ever come through without a ttm_tt.

drm/amdgpu/vm: Check PRT uAPI flag instead of PTE flag

2025-11-19T23:08:37Z

This fixes sparse mappings (aka. partially resident textures). Check the correct flags. Since a recent refactor, the code works with uAPI flags (for mapping buffer objects), and not PTE (page table entry) flags.

drm/amdgpu: Skip emit de meta data on gfx11 with rs64 enabled

2025-11-19T23:08:37Z

[Why] Accoreding to CP updated to RS64 on gfx11, WRITE_DATA with PREEMPTION_META_MEMORY(dst_sel=8) is illegal for CP FW. That packet is used for MCBP on F32 based system. So it would lead to incorrect GRBM write and FW is not handling that extra case correctly. [How] With gfx11 rs64 enabled, skip emit de meta data.

drm/amd: Skip power ungate during suspend for VPE

2025-11-19T23:08:36Z

During the suspend sequence VPE is already going to be power gated as part of vpe_suspend(). It's unnecessary to call during calls to amdgpu_device_set_pg_state(). It actually can expose a race condition with the firmware if s0i3 sequence starts as well. Drop these calls.

drm/amd/amdgpu: Ensure isp_kernel_buffer_alloc() creates a new BO

2025-11-12T03:51:27Z

When the BO pointer provided to amdgpu_bo_create_kernel() points to non-NULL, amdgpu_bo_create_kernel() takes it as a hint to pin that address rather than allocate a new BO. This functionality is never desired for allocating ISP buffers. A new BO should always be created when isp_kernel_buffer_alloc() is called, per the description for isp_kernel_buffer_alloc(). Ensure this by zeroing *bo right before the amdgpu_bo_create_kernel() call.
