drm/amdgpu/pp/smu7: use a local variable for toc indexing

2018-07-13T16:42:45+00:00

Rather than using the index variable stored in vram.  If
the device fails to come back online after a resume cycle,
reads from vram will return all 1s which will cause a
segfault. Based on a patch from Thomas Martitz .
This avoids the segfault, but we still need to sort out
why the GPU does not come back online after a resume.

drm/amd/powerplay: correct vega12 bootup values settings

2018-06-28T19:06:10+00:00

The vbios firmware structure changed between v3_1 and v3_2. So,
the code to setup bootup values needs different paths based
on header version.

2018-06-13T18:45:24+00:00

Gfxoff is already enabled in amdgpu_device_ip_set_powergating_state.
So, no need to enable it again in pp_late_init.

drm/amd/pp: Fix OD feature enable failed on Vega10 workstation cards

2018-06-13T18:45:23+00:00

As hw required, soc clock must large than mclk, So we set max soc
clock to OD Max Memory clk.
But on workstation, vbios do not support OD feature, the OD max memory
clock is equal to 0. In this case, driver can support underclocking.
and set od max memory clock to the value in highest memory dpm level.
So the od max memory clock should be less than highest soc clock.
and driver should not change the soc clock.

drm/amd/pp: initialize result to before or'ing in data

2018-06-13T18:45:22+00:00

The current use of result is or'ing in values and checking for
a non-zero result, however, result is not initialized to zero
so it potentially contains garbage to start with. Fix this by
initializing it to the first return from the call to
vega10_program_didt_config_registers.

Detected by cppcheck:
"(error) Uninitialized variable: result"
