2019-06-09drm/tegra: gem: Fix CPU-cache maintenance for BO's allocated using get_pages()Dmitry Osipenko
commit 61b51fb51c01a519a249d28ec55c6513a13be5a3 upstream. The allocated pages need to be invalidated in CPU caches. On ARM32 the DMA_BIDIRECTIONAL flag only ensures that data is written-back to DRAM and the data stays in CPU cache lines. While the DMA_FROM_DEVICE flag ensures that the corresponding CPU cache lines are getting invalidated and nothing more, that's exactly what is needed for a newly allocated pages. This fixes randomly failing rendercheck tests on Tegra30 using the Opentegra driver for tests that use small-sized pixmaps (10x10 and less, i.e. 1-2 memory pages) because apparently CPU reads out stale data from caches and/or that data is getting evicted to DRAM at the time of HW job execution.

2018-07-10drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULLBoris Brezillon
Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one.

2018-05-17drm/tegra: Acquire a reference to the IOVA cacheThierry Reding
The IOVA API uses a memory cache to allocate IOVA nodes from. To make sure that this cache is available, obtain a reference to it and release the reference when the cache is no longer needed. On 64-bit ARM this is hidden by the fact that the DMA mapping API gets that reference and never releases it. On 32-bit ARM, however, the DMA mapping API doesn't do that, so allocation of IOVA nodes fails.

2018-03-28drm/tegra: Let core take care of normalizing the zposPeter Ujfalusi
Set the drm_mode_config->normalize_zpos and call the generic drm_atomic_helper_check() instead of duplicating it within tegra_atomic_check(). Call tegra_display_hub_atomic_check() after the drm_atomic_helpre_check() returned without error.

2018-03-21Merge tag 'drm/tegra/for-4.17-rc1' of ↵Dave Airlie
git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.17-rc1 This fixes mmap() for fbdev devices by providing a custom implementation based on the KMS variant. This is a fairly exotic case these days, hence why it is not flagged for stable. There is also support for dedicating one of the overlay planes to serve as a hardware cursor on older Tegra that did support hardware cursors but not RGBA formats for it. Planes will now also export the IN_FORMATS property by supporting the various block-linear tiling modifiers for RGBA pixel formats. Other than that, there's a bit of cleanup of DMA API abuse, use of the private object infrastructure for global state (rather than subclassing atomic state objects) and an implementation of ->{begin,end}_cpu_access callbacks for PRIME exported buffers, which allow users to perform cache maintenance on these buffers. * tag 'drm/tegra/for-4.17-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: prime: Implement ->{begin,end}_cpu_access() drm/tegra: gem: Map pages via the DMA API drm/tegra: hub: Use private object for global state drm/tegra: fb: Properly support linear modifier drm/tegra: plane: Support format modifiers drm/tegra: dc: Dedicate overlay plane to cursor on older Tegra's drm/tegra: plane: Make tegra_plane_get_overlap_index() static drm/tegra: fb: Implement ->fb_mmap() callback drm/tegra: gem: Make __tegra_gem_mmap() available more widely drm/tegra: gem: Reshuffle declarations
2018-03-19drm/tegra: Shutdown on driver unbindThierry Reding
Since commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2."), removing the last framebuffer will no longer disable the corresponding pipeline, which causes the KMS core to complain about leaked connectors on driver unbind. Fix this by calling drm_atomic_helper_shutdown() on driver unbind, which will cause all display pipelines to be shut down and therefore drop the extra references on the connectors.
