A recent attempt to fix a ref count leak in amdgpu_display_crtc_set_config() turned out to be doing too much and "fixed" an intended decrease as if it were a leak. Undo that part to restore the proper balance. This is the very nature of this function to increase or decrease the power reference count depending on the situation. Consequences of this bug is that the power reference would eventually get down to 0 while the display was still in use, resulting in that display switching off unexpectedly.

Support for more than 8bpc was added recently in the driver but it defaults to the maximum supported bpc - locking out these modes. This should be a user configurable option such that the user can select what bpc configuration they would like. [How] This patch introduces the "max bpc" amdgpu driver specific connector property so the user can limit the maximum bpc. It ranges from 8 to 16. This doesn't directly set the preferred bpc for the panel since it follows Intel's existing driver conventions. This proprety should be removed once common drm support for max bpc lands. v2: rebase on upstream (Alex) Signed-off-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Sasha Levin <sashal@kernel.org> 2018-07-10T19:15:58+00:00 Junwei Zhang Jerry.Zhang@amd.com 2018-06-25T05:32:24+00:00 urn:sha1:bb812f1ea87dd7a4f336242212219268393ed308 Instead of calling gart address space on every bo pin, allocates it on demand v2: fix error handling v3: drop the change on amdgpu_amdkfd_gpuvm.c, not needed.

As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those.
