2023-08-16drm/amd: flush any delayed gfxoff on suspend entryMario Limonciello
DCN 3.1.4 is reported to hang on s2idle entry if graphics activity is happening during entry. This is because GFXOFF was scheduled as delayed but RLC gets disabled in s2idle entry sequence which will hang GFX IP if not already in GFXOFF. To help this problem, flush any delayed work for GFXOFF early in s2idle entry sequence to ensure that it's off when RLC is changed. commit 4b31b92b143f ("drm/amdgpu: complete gfxoff allow signal during suspend without delay") modified power gating flow so that if called in s0ix that it ensured that GFXOFF wasn't put in work queue but instead processed immediately. This is dead code due to commit 10cb67eb8a1b ("drm/amdgpu: skip CG/PG for gfx during S0ix") because GFXOFF will now not be explicitly called as part of the suspend entry code. Remove that dead code.

2023-08-16drm/amdgpu: skip xcp drm device allocation when out of drm resourceJames Zhu
Return 0 when drm device alloc failed with -ENOSPC in order to allow amdgpu drive loading. But the xcp without drm device node assigned won't be visiable in user space. This helps amdgpu driver loading on system which has more than 64 nodes, the current limitation. The proposal to add more drm nodes is discussed in public, which will support up to 2^20 nodes totally. kernel drm: https://lore.kernel.org/lkml/20230724211428.3831636-1-michal.winiarski@intel.com/T/ libdrm: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/305 Signed-off-by: James Zhu <James.Zhu@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2023-08-09drm/amdgpu: Match against exact bootloader statusLijo Lazar
On PSP v13.x ASICs, boot loader will set only the MSB to 1 and clear the least significant bits for any command submission. Hence match against the exact register value, otherwise a register value of all 0xFFs also could falsely indicate that boot loader is ready. Also, from PSP v13.0.6 and newer, bits[7:0] will be used to indicate command error status.

2023-08-09drm/amd: Disable S/G for APUs when 64GB or more host memoryMario Limonciello
Users report a white flickering screen on multiple systems that is tied to having 64GB or more memory. When S/G is enabled pages will get pinned to both VRAM carve out and system RAM leading to this. Until it can be fixed properly, disable S/G when 64GB of memory or more is detected. This will force pages to be pinned into VRAM. This should fix white screen flickers but if VRAM pressure is encountered may lead to black screens. It's a trade-off for now.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: "There are three areas of note: A bunch of strlcpy()->strscpy() conversions ended up living in my tree since they were either Acked by maintainers for me to carry, or got ignored for multiple weeks (and were trivial changes). The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees). For more details, see commit df8fc4e934c12b. The under-development compiler attribute __counted_by has been added so that we can start annotating flexible array members with their associated structure member that tracks the count of flexible array elements at run-time. It is possible (likely?) that the exact syntax of the attribute will change before it is finalized, but GCC and Clang are working together to sort it out. Any changes can be made to the macro while we continue to add annotations. As an example of that last case, I have a treewide commit waiting with such annotations found via Coccinelle: https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b Also see commit dd06e72e68bcb4 for more details.

2023-06-23drm/amdgpu: fix clearing mappings for BOs that are always valid in VMSamuel Pitoiset
Per VM BOs must be marked as moved or otherwise their ranges are not updated on use which might be necessary when the replace operation splits mappings. This fixes random GPU hangs when replacing sparse mappings from the userspace, while OP_MAP/OP_UNMAP works fine because always valid BOs are correctly handled there.

2023-06-23drm/amdgpu: Remove CONFIG_DEBUG_FS guard around body of ↵Nathan Chancellor
amdgpu_rap_debugfs_init() After commit 8020f0f9316b ("drm/amd/amdgpu: enable W=1 for amdgpu"), there is an instance of -Wunused-const-variable when CONFIG_DEBUG_FS is disabled: drivers/gpu/drm/amd/amdgpu/amdgpu_rap.c:110:37: error: unused variable 'amdgpu_rap_debugfs_ops' [-Werror,-Wunused-const-variable] 110 | static const struct file_operations amdgpu_rap_debugfs_ops = { | ^ 1 error generated. There is no reason for the body of this function to be guarded when CONFIG_DEBUG_FS is disabled, as debugfs_create_file() is a stub that just returns an error pointer in that situation.
