2021-03-24drm/amdgpu: define address map for host xgmi link (v3)Rajneesh Bhardwaj3-5/+35
This applies to AMD Accelerated Processing Platforms that support host gpu interconnect throguh a special link (xgmi). Aldebaran systems will support this special feature for utilizing the benefits of host-gpu cache coherence. This change outlines the basic framework for mapping the GPU VRAM (HBM) to system address space making it accesible to the host but managed by the amdgpu driver since this region is marked as reserved memory in host address space by the underlying system firmware. v2: switch to smuio callback function to check the type of host-gpu interface (Hawking) v3: use hub callbacks rather than direct function calls (Alex) Reviewed-by: Oak Zeng <oak.zeng@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@amd.com> Signed-off-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2021-03-24drm/amdgpu: enable xgmi support for AldebaranRajneesh Bhardwaj1-1/+3
Like its predecessors Aldebran also supports advanced high bandwidth GPU-GPU communication interface known as xgmi. This enables the basic xgmi support while refactoring the code slightly. Detection of xgmi link between host cpu and gpu will be introduced in a different patch.

Commit 41401ac67791 added FPU wrappers to dcn21_validate_bandwidth(), which was correct. Unfortunately a nested function alredy contained DC_FP_START()/DC_FP_END() calls, which results in nested FPU context enter/exit and complaints by kernel_fpu_begin_mask(). This can be observed e.g. with 5.10.20, which backported 41401ac67791 and now emits the following warning on boot: WARNING: CPU: 6 PID: 858 at arch/x86/kernel/fpu/core.c:129 kernel_fpu_begin_mask+0xa5/0xc0 Call Trace: dcn21_calculate_wm+0x47/0xa90 [amdgpu] dcn21_validate_bandwidth_fp+0x15d/0x2b0 [amdgpu] dcn21_validate_bandwidth+0x29/0x40 [amdgpu] dc_validate_global_state+0x3c7/0x4c0 [amdgpu] The warning is emitted due to the additional DC_FP_START/END calls in patch_bounding_box(), which is inlined into dcn21_calculate_wm(), its only caller. Removing the calls brings the code in line with dcn20 and makes the warning disappear.
