drm/amdgpu/virtual_dce: Virtual display doesn't support disable vblank immediately

2017-08-29T19:27:38+00:00

For virtual display, it uses software timer to emulate the vsync interrupt,
it doesn't have high precision, so doesn't support disable vblank immediately.

2017-08-02T02:43:12+00:00

- Stop reprogramming the MC, the vbios already does this in asic_init
- Reduce internal gart to 256M (this does not affect the ttm GTT pool size)
- Initial support for huge pages
- Rework bo migration logic
- Lots of improvements for vega10
- Powerplay fixes
- Additional Raven enablement
- SR-IOV improvements
- Bug fixes
- Code cleanup

drm/amdgpu: Allow vblank_disable_immediate.

2017-07-14T15:05:51+00:00

With instantaneous high precision vblank timestamping
that updates at leading edge of vblank, a cooked hw
vblank counter which increments at leading edge of
vblank, and reliable page flip execution and completion
at leading edge of vblank, we should meet the requirements
for fast/immediate vblank irq disable/enable.

Testing on Linux-4.12-rc5 + drm-next on a Radeon R9 380
Tonga Pro (DCE 10) with timing measurement equipment
indicates this works fine, so allow immediate vblank
disable for power saving.

For debugging in case of unexpected trouble, booting
with kernel cmdline option drm.vblankoffdelay=0
(or echo 0 > /sys/module/drm/parameters/vblankoffdelay)
would keep vblank irqs permanently on to approximate old
behavior.

Merge remote-tracking branch 'airlied/drm-next' into drm-misc-next

2017-06-27T13:18:17+00:00

Required for Daniel's drm_vblank_cleanup cleanup

drm/amd|radeon: Drop drm_vblank_cleanup

2017-06-23T09:08:44+00:00

Both drivers shut down all crtc beforehand already, which will shut up
any pending vblank (the only thing vblank_cleanup really does is
disable the disable timer). Hence we don't need this here and can
remove it.

drm/amdgpu:don't invoke srio-gpu-reset in gpu-reset (v2)

2017-05-24T21:40:37+00:00

because we don't want to do sriov-gpu-reset under certain
cases, so just split those two funtion and don't invoke
sr-iov one from bare-metal one.

V2:
remove debugfs_gpu_reset routine on SRIOV case.
