drm/tegra: gem: Make __tegra_gem_mmap() available more widely

2018-03-08T13:38:30Z

This function allows mapping a GEM object into a virtual memory address space, which makes it useful outside of the GEM code. While at it, rename the function so it doesn't clash with the function that implements the DRM_TEGRA_GEM_MMAP IOCTL. Signed-off-by: Thierry Reding

drm/tegra: gem: Reshuffle declarations

2018-03-08T13:38:05Z

Move declarations in the gem.h header file into the same order as the corresponding definitions in gem.c. Signed-off-by: Thierry Reding

drm/tegra: Use .dumb_map_offset and .dumb_destroy defaults

2017-08-16T18:13:48Z

This driver can use the drm_driver.dumb_destroy and drm_driver.dumb_map_offset defaults, so no need to set them. Cc: Thierry Reding Signed-off-by: Noralf Trønnes Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/1502034068-51384-7-git-send-email-noralf@tronnes.org

drm/tegra: Check for malformed offsets and sizes in the 'submit' IOCTL

2017-06-15T12:16:07Z

If commands buffer claims a number of words that is higher than its BO can fit, a kernel OOPS will be fired on the out-of-bounds BO access. This was triggered by an opentegra Xorg driver that erroneously pushed too many commands to the pushbuf. The CDMA commands buffer address is 4 bytes aligned, so check its alignment. The maximum number of the CDMA gather fetches is 16383, add a check for it. Add a sanity check for the relocations in a same way.

drm/tegra: gem: Use more consistent data types

2014-11-13T15:18:32Z

Use size_t consistently for sizes and u32/u64 instead of uint32_t and uint64_t. Signed-off-by: Thierry Reding

drm/tegra: Add IOMMU support

2014-11-13T15:14:48Z

When an IOMMU device is available on the platform bus, allocate an IOMMU domain and attach the display controllers to it. The display controllers can then scan out non-contiguous buffers by mapping them through the IOMMU. Signed-off-by: Thierry Reding

drm/tegra: Implement more tiling modes

2014-08-04T08:07:34Z

Tegra124 supports a block-linear mode in addition to the regular pitch linear and tiled modes. Add support for these by moving the internal representation into a structure rather than a simple flag. Tested-by: Alexandre Courbot Signed-off-by: Thierry Reding

drm/tegra: Relicense under GPL v2

2014-04-04T07:12:51Z

The majority of the code in this driver is licensed under the GPL v2, so relicense the rest under GPL v2 as well for consistency. Acked-by: Stephen Warren Signed-off-by: Thierry Reding

drm/tegra: Add PRIME support

2013-12-20T14:56:07Z

Implement very basic PRIME support. This currently only works with buffers that are contiguous in memory and will refuse to import any physically non-contiguous buffers. Signed-off-by: Thierry Reding
