2015-10-02drm/amdgpu: add pm sysfs files lateAlex Deucher1-4/+6
They were added relatively early in the driver init process which meant that in some cases the driver was not finished initializing before external tools tried to use them which could result in a crash depending on the timing.

2015-09-03drm/amdgpu/cz: fix cz_dpm_update_low_memory_pstate logicAlex Deucher1-2/+2
The logic was reversed. This feature is not enabled at the moment, but fix it now for the future. Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2015-07-23drm/amdgpu/cz/dpm: properly report UVD and VCE clock levelsAlex Deucher1-16/+45
VCE, UVD DPM work similarly to SCLK DPM. Report the current clock levels for UVD and VCE via debugfs. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2015-07-23drm/amdgpu/cz: implement voltage validation properlyAlex Deucher1-7/+16
CZ uses a different set of registers compared to previous asics and supports separate NB and GFX planes. Reviewed-by: Jammy Zhou <Jammy.Zhou@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2015-07-16drm/amdgpu/cz: store the forced dpm levelAlex Deucher1-0/+2
So the selected forced level shows up properly in sysfs. Reviewed-by: Jammy Zhou <Jammy.Zhou@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2015-07-16drm/amdgpu/cz: unforce dpm levels before forcing to low/highAlex Deucher1-1/+7
This is necessary to properly reset the min/max limits before clamping them otherwise we may get improper clamping depending on what what was the last forced level. Reviewed-by: Jammy Zhou <Jammy.Zhou@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2015-06-10drm/amdgpu: enable vce powergatingSonny Jiang1-4/+128
Enable VCE dpm and powergating. VCE dpm dynamically scales the VCE clocks on demand. Signed-off-by: Sonny Jiang <sonny.jiang@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
2015-06-10drm/amdgpu/cz: don't call smu_init on resumeAlex Deucher1-7/+8
smu_init allocates buffers and initializes them. It does not touch the hw. There is no need to do it again on resume. It should really be part of sw_init (and smu_fini should be part of sw_fini), but we need the firmware sizes from the other IPs for firmware loading so we have to wait until sw init is done for all other IPs.

2015-06-03drm/amdgpu: enable uvd dpm and powergatingSonny Jiang1-2/+88
Enable UVD dpm (dynamic power management) and powergating. UVD dpm dynamically scales the UVD clocks on demand. Powergating turns off the power to the block when it's not in use.

This adds initial support for VI asics. This includes Iceland, Tonga, and Carrizo. Our inital focus as been Carrizo, so there are still gaps in support for Tonga and Iceland, notably power management.
