2017-10-19drm/amdgpu: busywait KIQ register accessing (v4)pding
Register accessing is performed when IRQ is disabled. Never sleep in this function. Known issue: dead sleep in many use cases of index/data registers. v2: - wrap polling fence functions. - don't trigger IRQ for polling in case of wrongly fence signal. v3: - handle wrap round gracefully. - add comments for polling function v4: - don't return negative timeout confused with error code Signed-off-by: pding <Pixel.Ding@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2017-09-28drm/amdgpu: add option for force enable multipipe policy for computeAndres Rodriguez

2017-09-28drm/amdgpu: use multipipe compute policy on non PL11 asicsAndres Rodriguez
A performance regression for OpenCL tests on Polaris11 had this feature disabled for all asics. Instead, disable it selectively on the affected asics.

this way after KIQ MQD released in drv unloading, CPC can still let KIQ access this MQD thus RLCV SAVE_VF will not fail v2: always use VRAM domain for KIQ MQD no matter BM or SRIOV Signed-off-by: Monk Liu <Monk.Liu@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2017-01-27drm/amdgpu: simplify allocation of scratch regsNils Wallménius
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.

2016-10-25drm/amdgpu: change function declarations and add missing header dependenciesBaoyou Xie
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.
