There is a new version of DMC available for CNL. The release notes mentions: 1. Fix for the issue where DC_STATE was getting enabled even when disabled by driver causing data corruption v2: Since the firmware is merged to linux-firmware.git, add MODULE_FIRMWARE. v3: rebased.

git://git.armlinux.org.uk/~rmk/linux-arm into drm-next This series builds upon the set of fixes previously submitted to move Armada DRM closer to atomic modeset. We're nowhere near yet, but this series helps to get us closer by unifying some of the differences between the primary and overlay planes. New features added allows userspace to disable the primary plane if overlay is full screen and there's nothing obscuring the colorkey - this saves having to fetch an entire buffer containing nothing but colorkey when displaying full screen video.

2018-01-04drm/i915: Pass DMA_ATTR_NO_WARN to dma_map_sg()Chris Wilson1-3/+4
In some iommu, e.g. swiotlb, the available space can be quite limited. So we employ a trial-and-error approach to seeing if our large contiguous chunks can fit, and if that fails we try again with smaller chunks after trying to free our own lazily allocated blobs. As we use a trial-and-error approach, we do not want dma_map_sg() to emit a WARN of its own accord, we want to gracefully report the error back to the caller instead. Note that our noisy culprit, swiotlb, doesn't honour the flag, yet.

2018-01-04drm/i915: Apply Display WA #1183 on skl, kbl, and cflLucas De Marchi3-9/+38
Display WA #1183 was recently added to workaround "Failures when enabling DPLL0 with eDP link rate 2.16 or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz (CDCLK_CTL CD Frequency Select 10b or 11b) used in this enabling or in previous enabling." This workaround was designed to minimize the impact only to save the bad case with that link rates. But HW engineers indicated that it should be safe to apply broadly, although they were expecting the DPLL0 link rate to be unchanged on runtime. We need to cover 2 cases: when we are in fact enabling DPLL0 and when we are just changing the frequency with small differences.

The GPU exec state may have changed at the time when the perfmon sampling is done, as it reflects the state of the last submission, not the current GPU execution state. So for proper sampling we must use the submit exec_state. Signed-off-by: Lucas Stach <[email protected]>
2018-01-02drm/etnaviv: move exec_state to submit objectLucas Stach6-11/+10
We'll need this in some places where only the submit is available. Also this is a first step at slimming down the cmdbuf object. Signed-off-by: Lucas Stach <[email protected]>
2018-01-02drm/etnaviv: move PMRs to submit objectLucas Stach6-49/+44
To make them available to the event worker even after the actual command stream execution has finished. Signed-off-by: Lucas Stach <[email protected]>
2018-01-02drm/etnaviv: refcount the submit objectLucas Stach2-2/+13
The submit object lifetime will get extended to the actual GPU execution. As multiple users will depend on this, add a kref to properly control destruction of the object. Signed-off-by: Lucas Stach <[email protected]> Reviewed-by: Philipp Zabel <[email protected]>
2018-01-02drm/etnaviv: move ww_acquire_ctx out of submit objectLucas Stach2-10/+13
The acquire_ctx is special in that it needs to be released from the same thread as has been used to initialize it. This collides with the intention to extend the submit lifetime beyond the gem_submit function with potentially other threads doing the final cleanup. Move the ww_acquire_ctx to the function local stack as suggested in the documentation. Signed-off-by: Lucas Stach <[email protected]> Reviewed-by: Philipp Zabel <[email protected]>
2018-01-02drm/etnaviv: move object unpinning to submit cleanupLucas Stach1-21/+12
This is safe to call in all paths, as the BO_PINNED flag tells us if the BO needs unpinning. Signed-off-by: Lucas Stach <[email protected]> Reviewed-by: Philipp Zabel <[email protected]>
2018-01-02drm/etnaviv: attach in fence to submit and move fence wait to fence_syncLucas Stach2-16/+14
Simplifies the cleanup path and moves fence waiting to a central location. Signed-off-by: Lucas Stach <[email protected]> Reviewed-by: Philipp Zabel <[email protected]>
2018-01-02drm/etnaviv: rename submit fence to out_fenceLucas Stach3-9/+9
This is the fence passed out on a sucessful GPU submit. Make the name more clear. Signed-off-by: Lucas Stach <[email protected]>
2018-01-02drm/etnaviv: move object fence attachment to gem_submit pathLucas Stach2-7/+21
The object fencing has nothing to do with the actual GPU buffer submit, so move it to the gem submit path to have a cleaner split. Signed-off-by: Lucas Stach <[email protected]> Reviewed-by: Philipp Zabel <[email protected]>
