2017-08-28drm/vmwgfx: Add support for imported Fence File DescriptorSinclair Yeh
This allows vmwgfx to wait on a fence created by another device. v2: * Remove special handling for vmwgfx fence and just use dma_fence_wait() * Use interruptible waits * Added function documentation Signed-off-by: Sinclair Yeh <syeh@vmware.com> Reviewed-by: Deepak Singh Rawat <drawat@vmware.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com>

2017-08-28drm/vmwgfx: Fix incorrect command header offset at restartThomas Hellstrom
Sometimes it appears like the device modifies the command header offset member. So explicitly clear it when restarting after an error. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>
2017-08-28drm/vmwgfx: Support the NOP_ERROR commandThomas Hellstrom
Can be used by user-space applications to test and verify the kernel command buffer error recovery functionality. Malicious user-space apps could potentially use this command to slow down graphics processing somewhat, but they could also accomplish the same thing using a random malformed command so this should be considered safe. At least as safe as it gets. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Brian Paul <brianp@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>
2017-08-28drm/vmwgfx: Restart command buffers after errorsThomas Hellstrom
Previously we skipped the command buffer and added an extra fence to avoid hangs due to skipped fence commands. Now we instead restart the command buffer after the failing command, if there are any commands left. In addition we print out some information about the failing command and its location in the command buffer. Testing Done: ran glxgears using mesa modified to send the NOP_ERROR command before each 10th clear and verified that we detected the device error properly and that there were no other device errors caused by incorrectly ordered command buffers. Also ran the piglit "quick" test suite which generates a couple of device errors and verified that they were handled as intended.

2017-08-28drm/vmwgfx: Move irq bottom half processing to threadsThomas Hellstrom
This gets rid of the irq bottom half tasklets and instead performs the work needed in process context. We also convert irq-disabling spinlocks to ordinary spinlocks. This should decrease system latency for other system components, like sound for example but has the potential to increase latency for processes that wait on the GPU.

2017-08-25drm/exynos: consistent use of cppTobias Jakobi
A recent commit (272725c7db4da1fd3229d944fc76d2e98e3a144e) has removed the use of 'bits_per_pixel' in DRM. However the corresponding Exynos driver code still uses the ambiguous 'bpp', even though it is now initialized from fb->cpp[0]. Consistenly use 'cpp' in FIMD, DECON7 and DECON5433 drivers.

2017-08-25drm/exynos: mixer: remove src offset from mixer_graph_buffer()Tobias Jakobi

2017-08-25drm/exynos: mixer: enable NV12MT support for the video planeTobias Jakobi
The video processor supports a tiled version of the NV12 format, known as NV12MT in V4L2 terms. The support was removed in commit 083500baefd5f4c215a5a93aef2492c1aa775828 due to not being a real pixel format, but rather NV12 with a special memory layout. With the introduction of FB modifiers, we can now properly support this format again. Tested with a hacked up modetest from libdrm's test suite on an ODROID-X2 (Exynos4412).

2017-08-25drm/exynos/decon5433: use mode info stored in CRTC to detect i80 modeAndrzej Hajda
Since panel's mode of work is propagated properly from panel to DECON, there is no need to use redundant private device tree property. The only issue with such approach is that check for required interrupts should be postponed until panel communicate its requirements, ie to mode validation phase - mode_valid callback.

2017-08-25drm/exynos: add mode_valid callback to exynos_drmAndrzej Hajda

2017-08-25drm/exynos/dsi: refactor panel detection logicAndrzej Hajda
Description of drm_helper_hpd_irq_event clearly states that drivers supporting hotplug events per connector should use different helper - drm_kms_helper_hotplug_event. To achieve it following changes have been performed: - moved down all DSI ops - they require exynos_dsi_disable function to be defined earlier, - simplified exynos_dsi_detect - there is no real detection, it just returns if panel is attached, - DSI attach/detach callbacks attaches/detaches DRM panel and sets connector status and other context fields accordingly, all this is performed under mutex, as these callbacks are asynchronous.
