drm/amdgpu/gmc: move vram type fetching into sw_init

2016-04-20T06:41:56+00:00

commit d1518a1db31a25682ea09c4b135fa72d9883be42 upstream. early_init gets called before atom asic init so on non-posted cards, the vram type is not initialized. Reviewed-by: Harish Kasiviswanathan Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: disable runtime pm on PX laptops without dGPU power control

2016-04-12T16:08:59+00:00

commit bedf2a65c1aa8fb29ba8527fd00c0f68ec1f55f1 upstream. Some PX laptops don't provide an ACPI method to control dGPU power. On those systems, the driver is responsible for handling the dGPU power state. Disable runtime PM on them until support for this is implemented.

drm/amdgpu: Fix error handling in amdgpu_flip_work_func.

2016-03-16T15:43:00+00:00

commit 90e94b160c7f647ddffda707f5e3c0c66c170df8 upstream. The patch e1d09dc0ccc6: "drm/amdgpu: Don't hang in amdgpu_flip_work_func on disabled crtc." from Feb 19, 2016, leads to the following static checker warning, as reported by Dan Carpenter in https://lists.freedesktop.org/archives/dri-devel/2016-February/101987.html drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:127 amdgpu_flip_work_func() warn: should this be 'repcnt == -1' drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:136 amdgpu_flip_work_func() error: double unlock 'spin_lock:&crtc->dev->event_lock' drivers/gpu/drm/amd/amdgpu/amdgpu_display.c:136 amdgpu_flip_work_func() error: double unlock 'irqsave:flags' This patch fixes both reported problems: Change post-decrement of repcnt to pre-decrement, so it can't underflow anymore, but still performs up to three repetitions - three is the maximum one could expect in practice. Move the spin_unlock_irqrestore to where it actually belongs.

drm/amdgpu: fix topaz/tonga gmc assignment in 4.4 stable

When upstream commit 429c45deae6e57f1bb91bfb05b671063fb0cef60 was applied to 4.4 as d60703ca942e8d044d61360bc9792fcab54b95d0 it applied incorrectly to the tonga_ip_blocks array rather than the topaz_ip_blocks array.

drm/amdgpu: return from atombios_dp_get_dpcd only when error

2016-03-09T23:34:52+00:00

commit 0b39c531cfa12dad54eac238c2e303b994df1ef7 upstream. In amdgpu_connector_hotplug(), we need to start DP link training only after we have received DPCD. The function amdgpu_atombios_dp_get_dpcd() returns non-zero value only when an error condition is met, otherwise returns zero. So in case the function encounters an error, we need to skip rest of the code and return from amdgpu_connector_hotplug() immediately. Only when we are successfull in reading DPCD pin, we should carry on with turning-on the monitor. Signed-off-by: Arindam Nath Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
