2019-02-05drm/vmwgfx: Also check for crtc status while checking for DU activeDeepak Rawat1-1/+1
During modeset check it is possible to have all crtc_state's in atomic state. Check for crtc enable status while checking for display unit active status. Only error if enabling a crtc while display unit is not active.

2019-02-05drm/vmwgfx: Return error code from vmw_execbuf_copy_fence_userThomas Hellstrom1-1/+1
The function was unconditionally returning 0, and a caller would have to rely on the returned fence pointer being NULL to detect errors. However, the function vmw_execbuf_copy_fence_user() would expect a non-zero error code in that case and would BUG otherwise. So make sure we return a proper non-zero error code if the fence pointer returned is NULL.

2019-02-01drm/sun4i: tcon: Prepare and enable TCON channel 0 clock at initPaul Kocialkowski1-0/+2
When initializing clocks, a reference to the TCON channel 0 clock is obtained. However, the clock is never prepared and enabled later. Switching from simplefb to DRM actually disables the clock (that was usually configured by U-Boot) because of that. On the V3s, this results in a hang when writing to some mixer registers when switching over to DRM from simplefb. Fix this by preparing and enabling the clock when initializing other clocks. Waiting for sun4i_tcon_channel_enable to enable the clock is apparently too late and results in the same mixer register access hang.

2019-02-01drm/amdgpu: fix the incorrect external id for raven seriesHuang Rui1-2/+4
This patch fixes the incorrect external id that kernel reports to user mode driver. Raven2's rev_id is starts from 0x8, so its external id (0x81) should start from rev_id + 0x79 (0x81 - 0x8). And Raven's rev_id should be 0x21 while rev_id == 1.

2019-01-30drm/amdgpu: Transfer fences to dmabuf importerChris Wilson1-8/+51
amdgpu only uses shared-fences internally, but dmabuf importers rely on implicit write hazard tracking via the reservation_object.fence_excl. For example, the importer use the write hazard for timing a page flip to only occur after the exporter has finished flushing its write into the surface. As such, on exporting a dmabuf, we must either flush all outstanding fences (for we do not know which are writes and should have been exclusive) or alternatively create a new exclusive fence that is the composite of all the existing shared fences, and so will only be signaled when all earlier fences are signaled (ensuring that we can not be signaled before the completion of any earlier write). v2: reservation_object is already locked by amdgpu_bo_reserve() v3: Replace looping with get_fences_rcu and special case the promotion of a single shared fence directly to an exclusive fence, bypassing the fence array. v4: Drop the fence array ref after assigning to reservation_object Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107341 Testcase: igt/amd_prime/amd-to-i915 References: 8e94a46c1770 ("drm/amdgpu: Attach exclusive fence to prime exported bo's.

Add missing break statement in order to prevent the code from falling through to the default case. The resoning for this is that pclk_vol_table is an automatic variable. So, it makes no sense to update it just before falling through to the default case and return -EINVAL. This bug was found thanks to the ongoing efforts to enabling -Wimplicit-fallthrough.

2019-01-24drm/msm: Fix A6XX support for opp-levelDouglas Anderson1-1/+1
The bindings for Qualcomm opp levels changed after being Acked but before landing. Thus the code in the GPU driver that was relying on the old bindings is now broken. Let's change the code to match the new bindings by adjusting the old string 'qcom,level' to the new string 'opp-level'. See the patch ("dt-bindings: opp: Introduce opp-level bindings"). NOTE: we will do additional cleanup to totally remove the string from the code and use the new dev_pm_opp_get_level() but we'll do it in a future patch. This will facilitate getting the important code fix in sooner without having to deal with cross-maintainer dependencies. This patch needs to land before the patch ("arm64: dts: sdm845: Add gpu and gmu device nodes") since if a tree contains the device tree patch but not this one you'll get a crash at bootup.

2019-01-23gpu: ipu-v3: pre: don't trigger update if buffer address doesn't changeLucas Stach1-0/+6
On a NOP double buffer update where current buffer address is the same as the next buffer address, the SDW_UPDATE bit clears too late. As we are now using this bit to determine when it is safe to signal flip completion to userspace this will delay completion of atomic commits where one plane doesn't change the buffer by a whole frame period. Fix this by remembering the last buffer address and just skip the double buffer update if it would not change the buffer address.

2019-01-22drm/sun4i: hdmi: Fix usage of TMDS clockPriit Laes1-0/+4
Although TMDS clock is required for HDMI to properly function, nobody called clk_prepare_enable(). This fixes reference counting issues and makes sure clock is running when it needs to be running. Due to TDMS clock being parent clock for DDC clock, TDMS clock was turned on/off for each EDID probe, causing spurious failures for certain HDMI/DVI screens.

The device node iterators perform an of_node_get on each iteration, so a jump out of the loop requires an of_node_put. Remote and port also have augmented reference counts, so drop them on each iteration and at the end of the function, respectively.
