From: Thierry Reding <treding@xxxxxxxxxx> Hi, This series adds libdrm-tegra with a very lightweight API on top of the kernel interfaces. Most of the functions provided here have been in use in various driver efforts in different incarnations. This is an attempt to consolidate, so I'm looking for review comments especially by Erik to ensure it can be used by grate. I've used these to implement basic EXA support in xf86-video-opentegra, which I've pushed to a repository here[0]. The libdrm patches are also available in a repository[1] for convenience. Patch 1 adds support for symbol visibility if GCC supports it. This is used by later patches to make only the public symbols visible in the libdrm-tegra shared object. Patch 2 adds support for managing a Tegra DRM object (which doesn't do a whole lot more than wrap a file descriptor) and buffer objects. A small test program is added in patch 3 to check that a Tegra DRM object can be created on top of a DRM device. Patch 4 adds functions to open a channel to an engine (gr2d or gr3d), create and manage a job as well as compose command streams in a push buffer and wait for a fence. To make it easier to write further tests, patch 5 introduces some DRM helpers to setup a screen and attach framebuffers to it. A very basic interface is also provided for the gr2d unit, which can be used to do a solid rectangle fill. The helpers introduced in patch 5 are used in patch 6 to fill a sub- region of the screen with a solid color. Finally patch 7 clears two IOCTL argument buffers when compiled with valgrind support to eliminate some complaints raised by valgrind when running the newly introduced Tegra tests.
