* Merge tag 'drm/tegra/for-4.18-rc1' of ↵Dave Airlie2018-05-2212-315/+594
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.18-rc1 This set enables IOMMU support in the gr2d and gr3d drivers and adds support for the zpos property on older Tegra generations. It also enables scaling filters and incorporates some rework to eliminate a private wrapper around struct drm_framebuffer. The remainder is mostly a random assortment of fixes and cleanups, as well as some preparatory work for destaging the userspace ABI, which is almost ready and is targetted for v4.19-rc1.

| * drm/tegra: Acquire a reference to the IOVA cacheThierry Reding2018-05-171-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

| | * | drm/tegra: dc: Dedicate overlay plane to cursor on older Tegra'sDmitry Osipenko2018-03-151-5/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Older Tegra's do not support RGBA format for the cursor, but instead overlay plane could be used for it. Since there is no much use for the overlays on a regular desktop and HW-accelerated cursor is much better than a SW cursor, let's dedicate one overlay plane to the mouse cursor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes hangs with legacy applications that use the mmap() syscall on the fbdev device to map framebuffer memory. The fbdev implementation for mmap() creates a mapping that conflicts with DRM usage and causes a hang when the memory is accessed through the mapping.

This could cause potential problems if the return value is used in arithmetic operations with a 32-bit reference HW vblank count. Explicitly typecasting this down to u32 either fixes a potential problem or serves to add clarity in case the implicit typecasting was already correct.
