2023-10-10x86/cpu: Encapsulate topology information in cpuinfo_x86Thomas Gleixner
The topology related information is randomly scattered across cpuinfo_x86. Create a new structure cpuinfo_topo and move in a first step initial_apicid and apicid into it. Aside of being better readable this is in preparation for replacing the horribly fragile CPU topology evaluation code further down the road. Consolidate APIC ID fields to u32 as that represents the hardware type. No functional change.

2023-10-03drm/amdkfd: drop struct kfd_cu_infoAlex Deucher
I think this was an abstraction back from when kfd supported both radeon and amdgpu. Since we just support amdgpu now, there is no more need for this and we can use the amdgpu structures directly. This also avoids having the kfd_cu_info structures on the stack when inlining which can blow up the stack.

2023-09-26drm/amdkfd: Handle errors from svm validate and mapPhilip Yang
If new range is splited to multiple pranges with max_svm_range_pages alignment and added to update_list, svm validate and map should keep going after error to make sure prange->mapped_to_gpu flag is up to date for the whole range. svm validate and map update set prange->mapped_to_gpu after mapping to GPUs successfully, otherwise clear prange->mapped_to_gpu flag (for update mapping case) instead of setting error flag, we can remove the redundant error flag to simpliy code. Refactor to remove goto and update prange->mapped_to_gpu flag inside svm_range_lock, to guarant we always evict queues or unmap from GPUs if there are invalid ranges. After svm validate and map return error -EAGIN, the caller retry will update the mapping for the whole range again.

2023-09-20drm/amdkfd: fix add queue process context clear without runtime enableJonathan Kim
There are cases where HSA runtime is not enabled through the AMDKFD_IOC_RUNTIME_ENABLE call when adding queues and the MES ADD_QUEUE API should clear the MES process context instead of SET_SHADER_DEBUGGER. Such examples are legacy HSA runtime builds that do not support the current exception handling and running KFD tests. The only time ADD_QUEUE.skip_process_ctx_clear is required is for debugger use cases where a debugged process is always runtime enabled when adding a queue.

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>
