drm/amdgpu/display: create fake mst encoders ahead of time (v4)

2020-07-22T07:34:27+00:00

commit 3168470142e0a82b5732c04ed4c031a9322ae170 upstream.

Prevents a warning in the MST create connector case.

v2: create global fake encoders rather per connector fake encoders
to avoid running out of encoder indices.

v3: use the actual number of crtcs on the asic rather than the max
to conserve encoders.

v4: v3 plus missing hunk I forgot to git add.

drm/amd/display: OLED panel backlight adjust not work with external display connected

2020-07-22T07:34:27+00:00

commit b448d30b0c303d5454ea572b772d1ffae96bc6e7 upstream.

[Why]
amdgpu_dm->backlight_caps is for single eDP only. the caps are upddated
for very connector. Real eDP caps will be overwritten by other external
display. For OLED panel, caps->aux_support is set to 1 for OLED pnael.
after external connected, caps+.aux_support is set to 0. This causes
OLED backlight adjustment not work.

[How]
within update_conector_ext_caps, backlight caps will be updated only for
eDP connector.

drm/amdgpu/sdma5: fix wptr overwritten in ->get_wptr()

2020-07-22T07:34:27+00:00

commit 05051496b2622e4d12e2036b35165969aa502f89 upstream.

"u64 *wptr" points to the the wptr value in write back buffer and
"*wptr = (*wptr) >> 2;" results in the value being overwritten each time
when ->get_wptr() is called.

umr uses /sys/kernel/debug/dri/0/amdgpu_ring_sdma0 to get rptr/wptr and
decode ring content and it is affected by this issue.

fix and simplify the logic similar as sdma_v4_0_ring_get_wptr().

v2: fix for sdma5.2 as well
v3: drop sdma 5.2 changes for 5.8 and stable

drm/amdgpu/powerplay: Modify SMC message name for setting power profile mode

2020-07-22T07:34:26+00:00

commit 98a34cf931e848f8489d3fb15a8f5fc03802ad65 upstream.

I consulted Cai Land(Chuntian.Cai@amd.com), he told me corresponding smc
message name to fSMC_MSG_SetWorkloadMask() is
"PPSMC_MSG_ActiveProcessNotify" in firmware code of Renoir.

Strange though it may seem, but it's a fact.

drm/amdgpu: add TMR destory function for psp

commit c564b8601ae917086751d90f464d5f19d731ece7 upstream.

TMR is required to be destoried with GFX_CMD_ID_DESTROY_TMR while the
system goes to suspend. Otherwise, PSP may return the failure state
(0xFFFF007) on Gfx-2-PSP command GFX_CMD_ID_SETUP_TMR after do multiple
times suspend/resume.

drm/amdgpu/atomfirmware: fix vram_info fetching for renoir

commit d7a6634a4cfba073ff6a526cb4265d6e58ece234 upstream.

Renoir uses integrated_system_info table v12.  The table
has the same layout as v11 with respect to this data.  Just
reuse the existing code for v12 for stable.

Fixes incorrectly reported vram info in the driver output.
