drm/tegra: Fix comparison operator for buffer size

2018-07-09T08:33:45+00:00

Here we are checking for the buffer length, not an offset for writing to, so using > is correct. The current code incorrectly rejects a command buffer ending at the memory buffer's end. Signed-off-by: Mikko Perttunen Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

Merge tag 'drm/tegra/for-4.18-rc1' of 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.

gpu: host1x: Rename relocarray -> relocs for consistency

2018-05-18T19:51:25+00:00

All other array variables use a plural, and this is the only one using the *array suffix. This is confusing, so rename it for consistency. Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Store pointer to client in jobs

2018-05-18T19:50:24+00:00

Rather than storing some identifier derived from the application context that can't be used concretely anywhere, store a pointer to the client directly so that accesses can be made directly through that client object.

gpu: host1x: Remove wait check support

2018-05-18T19:50:04+00:00

The job submission userspace ABI doesn't support this and there are no plans to implement it, so all of this code is dead and can be removed. Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Acquire a reference to the IOVA cache

2018-05-17T15:44:48+00:00

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.

drm/tegra: Fix order of teardown in IOMMU case

2018-05-17T15:44:48+00:00

The original code works fine, this is merely a cosmetic change to make the teardown order the reverse of the setup order. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Refactor IOMMU attach/detach

2018-05-17T12:08:40+00:00

Attaching to and detaching from an IOMMU uses the same code sequence in every driver, so factor it out into separate helpers. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: Let core take care of normalizing the zpos

2018-03-28T06:45:44+00:00

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.
