Holger Hoffstätte 15e8b95d5f drm/amd/display: Fix nested FPU context in dcn21_validate_bandwidth() ... Commit 41401ac677 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 41401ac677 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.
