drm/amdgpu: simplify allocation of scratch regs

2017-01-27T16:13:32+00:00

The scratch regs are sequential so there's no need to keep them in an array, we can just return the index of the first free register + the base register. Also change the array of bools for keeping track of the free regs to a bitfield. Reviewed-by: Christian König Signed-off-by: Nils Wallménius Signed-off-by: Alex Deucher

drm/amdgpu: change function declarations and add missing header dependencies

2016-10-25T18:38:58+00:00

We get a few warnings when building kernel with W=1: drivers/gpu/drm/amd/amdgpu/atombios_crtc.c:38:6: warning: no previous prototype for 'amdgpu_atombios_crtc_overscan_setup' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/dce_v8_0.c:661:6: warning: no previous prototype for 'dce_v8_0_disable_dce' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:40:5: warning: no previous prototype for 'amdgpu_gfx_scratch_get' [-Wmissing-prototypes] drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:62:6: warning: no previous prototype for 'amdgpu_gfx_scratch_free' [-Wmissing-prototypes] .... In fact, these functions are declared in drivers/gpu/drm/amd/amdgpu/atombios_crtc.h drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h drivers/gpu/drm/amd/amdgpu/dce_v8_0.h drivers/gpu/drm/amd/amdgpu/dce_v10_0.h drivers/gpu/drm/amd/amdgpu/dce_v11_0.h drivers/gpu/drm/amd/powerplay/inc/pp_acpi.h. So this patch adds missing header dependencies. By the way, this patch changes declaration of amdgpu_gfx_parse_disable_cu() to subject to its implement, and clean three function declarations in pp_acpi.h up.
