drm/amdgpu: missing bounds check in amdgpu_set_pp_force_state()

2016-06-17T17:50:10Z

There is no limit on high "idx" can go. It should be less than ARRAY_SIZE(data.states) which is 16. The "data" variable wasn't declared in that scope so I shifted the code around a bit to make it work. Also I made "idx" unsigned.

drm/amd/powerplay: add dpm force multiple levels on cz/tonga/fiji/polaris (v2)

2016-05-05T00:29:47Z

Allows you to force multiple levels rather than just one via the new sysfs interrface. v2: squash in: drm/amd/powerplay: ensure clock level set by user is valid. From Rex. Reviewed-by: Alex Deucher Signed-off-by: Eric Huang Signed-off-by: Alex Deucher

drm/amdgpu: Mark all instances of struct drm_info_list as const

drm/amdgpu/pm: update current crtc info after setting the powerstate

2016-03-02T16:01:20Z

On CI, we need to see if the number of crtcs changes to determine whether or not we need to upload the mclk table again. In practice we don't currently upload the mclk table again after the initial load. The only reason you would would be to add new states, e.g., for arbitrary mclk setting which is not currently supported.

drm/amdgpu/pm: adjust display configuration after powerstate

2016-02-22T16:31:02Z

set_power_state defaults to no displays, so we need to update the display configuration after setting up the powerstate on the first call. In most cases this is not an issue since ends up getting called multiple times at any given modeset and the proper order is achieved in the display changed handling at the top of the function.

drm/amd/powerplay: add some sysfs interfaces for powerplay.

2016-02-10T19:16:59Z

The new sysfs interfaces: pp_num_states: Read-only, return the number of all pp states, 0 if powerplay is not available. pp_cur_state: Read-only, return the index number of current pp state. pp_force_state: Read-write, to write a power state index will switch to selected state forcedly and enable forced state mode, disable forced state mode. such as "echo >...". pp_table: Read-write, binary output, to be used to read or write the dpm table, the maximum file size is 4KB of page size. pp_dpm_sclk: Read-write, reading will return a dpm levels list, to write an index number will force powerplay to set the corresponding dpm level. pp_dpm_mclk: same as sclk. pp_dpm_pcie: same as sclk. And add new setting "manual" to the existing interface power_dpm_force_performance_level. Reviewed-by: Alex Deucher Signed-off-by: Eric Huang Signed-off-by: Alex Deucher
