Hi Alex, After merging the amdgpu tree, today's linux-next build (powerpc allyesconfig) failed like this: In file included from drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:25: drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c: In function 'gfx_v10_0_cp_gfx_resume': drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:2628:27: error: 'CP_RB1_CNTL__BUF_SWAP_MASK' undeclared (first use in this function); did you mean 'CP_RB_CNTL__BUF_SWAP_MASK'? tmp = REG_SET_FIELD(tmp, CP_RB1_CNTL, BUF_SWAP, 1); ^~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu.h:1067:36: note: in definition of macro 'REG_FIELD_MASK' #define REG_FIELD_MASK(reg, field) reg##__##field##_MASK ^~~ drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:2628:8: note: in expansion of macro 'REG_SET_FIELD' tmp = REG_SET_FIELD(tmp, CP_RB1_CNTL, BUF_SWAP, 1); ^~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:2628:27: note: each undeclared identifier is reported only once for each function it appears in tmp = REG_SET_FIELD(tmp, CP_RB1_CNTL, BUF_SWAP, 1); ^~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu.h:1067:36: note: in definition of macro 'REG_FIELD_MASK' #define REG_FIELD_MASK(reg, field) reg##__##field##_MASK ^~~ drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:2628:8: note: in expansion of macro 'REG_SET_FIELD' tmp = REG_SET_FIELD(tmp, CP_RB1_CNTL, BUF_SWAP, 1); ^~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:2628:27: error: 'CP_RB1_CNTL__BUF_SWAP__SHIFT' undeclared (first use in this function); did you mean 'CP_RB0_CNTL__BUF_SWAP__SHIFT'? tmp = REG_SET_FIELD(tmp, CP_RB1_CNTL, BUF_SWAP, 1); ^~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu.h:1066:37: note: in definition of macro 'REG_FIELD_SHIFT' #define REG_FIELD_SHIFT(reg, field) reg##__##field##__SHIFT ^~~ drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:2628:8: note: in expansion of macro 'REG_SET_FIELD' tmp = REG_SET_FIELD(tmp, CP_RB1_CNTL, BUF_SWAP, 1); ^~~~~~~~~~~~~ Caused by commit a644d85a5cd4 ("drm/amdgpu: add gfx v10 implementation (v10)") I have disabled that driver for today. Please let me know when it is fixed so that I can enable it again. -- Cheers, Stephen Rothwell
