2016-09-22drm: Extract drm_plane.[hc]Daniel Vetter5-1001/+1044
Just pure code movement, cleanup and polish will happen in later patches. v2: Don't forget all the ioctl! To extract those cleanly I decided to put check_src_coords into drm_framebuffer.c (and give it a drm_framebuffer_ prefix), since that just checks framebuffer constraints. v3: rebase over PAGE_FLIP_TARGET.

2016-09-21drm/i915: start adding dp mst audioLibin Yang4-6/+53
(This patch is developed by Dave Airlie <airlied@redhat.com> originally) This patch adds support for DP MST audio in i915. Enable audio codec when DP MST is enabled if has_audio flag is set. Disable audio codec when DP MST is disabled if has_audio flag is set. Another separated patches to support DP MST audio will be implemented in audio driver. v2: Rebased.

2016-09-21drm/i915: Move audio_connector to intel_encoderPandiyan, Dhinakaran2-10/+6
With DP MST, a digital_port can carry more than one audio stream. Hence, more than one audio_connector needs to be attached to intel_digital_port in such cases. However, each stream is associated with an unique encoder. So, instead of creating an array of audio_connectors per port, move audio_connector from struct intel_digital_port to struct intel_encoder. This also simplifies access to the right audio_connector from codec functions in intel_audio.c that receive intel_encoder. v2: Removed locals that are not needed anymore. v3: No code change except for minor change in context.

Storing the port enum in intel_encoder makes it convenient to know the port attached to an encoder.

2016-09-21drm/i915/execlists: Reset RING registers upon resumeChris Wilson1-18/+30
There is a disparity in the context image saved to disk and our own bookkeeping - that is we presume the RING_HEAD and RING_TAIL match our stored ce->ring->tail value. However, as we emit WA_TAIL_DWORDS into the ring but may not tell the GPU about them, the GPU may be lagging behind our bookkeeping. Upon hibernation we do not save stolen pages, presuming that their contents are volatile. This means that although we start writing into the ring at tail, the GPU starts executing from its HEAD and there may be some garbage in between and so the GPU promptly hangs upon resume.

2016-09-21drm/rockchip: Always signal event in next vblank after cfg_doneTomasz Figa1-44/+10
This patch makes the driver send the pending vblank event in next vblank following the commit, relying on vblank signalling improvements done in previous patches. This gives us vblank events that always represent the real moment of changes hitting on the screen (which was the case only for complete FB changes before) and lets us remove the manual window update check.

2016-09-21drm/rockchip: Do not enable vblank without eventTomasz Figa1-11/+4
Originally we needed to enable vblank for any atomic commit to kick the PSR machine, but that was changed and we no longer need to do so from a vblank interrupt. Let's return to original behavior of enabling vblank only if it is really necessary. This essentially reverts commit 5b6804034ae9 ("drm/rockchip: Enable vblank without event").

2016-09-21drm/rockchip: Replace custom wait_for_vblanks with helperTomasz Figa3-78/+1
Currently the driver uses a custom function to wait for flip to complete after an atomic commit. It was needed before because of two problems: - there is no hardware vblank counter, so the original helper would have a race condition with the vblank interrupt, - the driver didn't support unreferencing cursor framebuffers asynchronously to the commit, which was what the helper expected. Since both problems have been solved by previous patches, we can now make the driver use the generic helper and remove custom waiting code. Signed-off-by: Tomasz Figa <tfiga@chromium.org>
2016-09-21drm/rockchip: Unreference framebuffers from flip workTomasz Figa1-0/+41
Currently the driver waits for vblank and then unreferences old framebuffers from atomic commit code path. This is however breaking the legacy cursor API, which requires the updates to be fully asynchronous. Instead of just adding a special case for cursor, we can have actually smaller amount of code to unreference any changed framebuffer from a flip work. Signed-off-by: Tomasz Figa <tfiga@chromium.org>
2016-09-21drm/rockchip: Avoid race with vblank count incrementTomasz Figa1-0/+34
Since VOP does not have a hardware vblank count register, the ongoing commit might be racing with a requested vblank interrupt, which would increment the software vblank counter before the changes being committed actually happen. To avoid this, we can extend .atomic_flush(), so after it sets cfg_done bit, it polls the vblank interrupt bit until it's inactive to make sure that any old vblank interrupt gets to the handler and then uses synchronize_irq(vop->irq) to make sure the handler finishes running. The polling case should happen very rarely, but even if, the total wait time should be relatively low and in practice almost equal to the vop hardirq handler running time.

2016-09-21drm/rockchip: Get rid of some unnecessary codeTomasz Figa1-18/+0

2016-09-21drm/rockchip: Clear interrupt status bits before enablingTomasz Figa1-0/+3
The enable register only masks the raw status bits to signal CPU interrupt only for enabled interrupts. The status bits are activated regardless of the enable register. This means that we might have an old interrupt event queued, which we are not interested in. To avoid getting a spurious interrupt signalled, we have to clear the old bit before we update the enable register. Signed-off-by: Tomasz Figa <tfiga@chromium.org>

2016-09-21drm/i915: Queue page flip work via a low latency, unbound workqueueImre Deak1-1/+1
While user space has control over the scheduling priority of its page flipping thread, the corresponding work the driver schedules for MMIO flips always runs from the generic system workqueue which has some scheduling overhead due it being CPU bound. This would hinder an application that wants more stringent guarantees over flip timing (to avoid missing a flip at the next frame count). Fix this by scheduling the work from the unbound system workqueue which provides for minimal scheduling latency. v2: - Use an unbound workqueue instead of a high-prio one. (Tvrtko, Chris) v3: - Use the system unbound wq instead of a dedicated one.

stih415 and stih416 platform are obsolete and no more supported. Only stih407 and stih410 platform are maintained. Signed-off-by: Vincent Abriou <vincent.abriou@st.com> Acked-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> Acked-by: Peter Griffin <peter.griffin@linaro.org>
2016-09-20drm/virtio: add real fence context and seqnoGustavo Padovan3-1/+3
virtio fences were created with no fence context, which would make then clash with an allocated fence context. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Message-id: 1472660813-28219-2-git-send-email-gustavo@padovan.org Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2016-09-20drm/virtio: drop virtio_gpu_execbuffer_ioctl() wrappingGustavo Padovan1-16/+8

2016-09-20virtio-gpu: avoid possible NULL pointer dereferenceHeinrich Schuchardt1-2/+4
If output is NULL it is not permissable to dereference it. So we should leave the respective function in this case. The inconsistency was indicated by cppcheck. No actual NULL pointer dereference was observed.

2016-09-20drm/qxl: reapply cursor after SetCrtc callsRay Strode2-1/+56
The qxl driver currently destroys and recreates the qxl "primary" any time the first crtc is set. A side-effect of destroying the primary is mouse state associated with the crtc is lost, which leads to disappearing mouse cursors on wayland sessions. This commit changes the driver to reapply the cursor any time SetCrtc is called. It achieves this by keeping a reference to the cursor bo on the qxl_crtc struct.

2016-09-20bochs: ignore device if there isn't enougth memoryGerd Hoffmann1-0/+7
The qemu stdvga can be configured with a wide range of video memory, from 1 MB to 256 MB (default is 16 MB). In case it is configured with only 1 or 2 MB it isn't really usable with bochsdrm, due to depths other than 32bpp not being supported so that isn't enough memory for a reasonable sized framebuffer. So skip the device and let vgacon or vesafb+fbcon handle the it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2016-09-20drm/i915: Unlock PPS registers after GPU resetImre Deak1-0/+1
Reapply the PPS register unlock workaround after GPU reset on platforms where the reset clobbers the display HW state. This at least gets rid of the related WARN during LVDS encoder enabling on PNV.

In atomic mode the crtc_xxx (eg crtc_hdisplay) members of the mode structure may be unset before calling atomic_check/commit for planes. Instead of, use xxx members which are actually set. Signed-off-by: Fabien Dessenne <fabien.dessenne@st.com> Acked-by: Vincent Abriou <vincent.abriou@st.com>
