2016-06-17drm/amdgpu: missing bounds check in amdgpu_set_pp_force_state()Dan Carpenter
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.

2016-03-02drm/amdgpu/pm: update current crtc info after setting the powerstateAlex Deucher
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.

2016-02-22drm/amdgpu/pm: adjust display configuration after powerstateAlex Deucher
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.

2016-02-10drm/amd/powerplay: add some sysfs interfaces for powerplay.Eric Huang
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.

2015-08-17drm/amdgpu: don't grab dev->struct_mutex in pm functionsDaniel Vetter
Similar to radeon, except that amdgpu doesn't even use struct_mutex to protect anything like the shared z buffer (sane gpu architecture, yay!). And the code already grabs the globa adev->ring_lock, so this code can't race with itself. Which makes struct_mutex completely redundnant. Remove it.
