This patch adds library and test application for g2d gpu(fimg2d). The fimg2d hardware is a 2D graphics accelerator(G2D) that supports Bit Block Transfer(BitBLT). The library includes the following primitive drawing operations: .solid fill - This operation fills the given buffer with the given color data. .copy - This operation copies contents in source buffer to destination buffer. .copy_with_scale - This operation copies contents in source buffer to destination buffer scaling up or down properly. .blend - This operation blends contents in source buffer with the ones in destination buffer. And the above operations uses gem handle or user space address allocated by malloc() as source or destination buffer. And the test application includes just simple primitive drawing tests with the above library. And the guide to test is as the following, "#exynos_fimg2d_test -s connector_id@crtc_id:mode" With this above simple command, four primitive drawing operations would be called step by step and also rendered on the output device to the given connector and crtc id.

libdrm - userspace library for drm This is libdrm, a userspace library for accessing the DRM, direct rendering manager, on Linux, BSD and other operating systes that support the ioctl interface. The library provides wrapper functions for the ioctls to avoid exposing the kernel interface directly, and for chipsets with drm memory manager, support for tracking relocations and buffers. libdrm is a low-level library, typically used by graphics drivers such as the Mesa DRI drivers, the X drivers, libva and similar projects. New functionality in the kernel DRM drivers typically requires a new libdrm, but a new libdrm will always work with an older kernel. Compiling --------- libdrm is a standard autotools packages and follows the normal configure, build and install steps. The first step is to configure the package, which is done by running the configure shell script: ./configure By default, libdrm will install into the /usr/local/ prefix. If you want to install this DRM to replace your system copy, pass --prefix=/usr and --exec-prefix=/ to configure. If you are building libdrm from a git checkout, you first need to run the autogen.sh script. You can pass any options to autogen.sh that you would other wise pass to configure, or you can just re-run configure with the options you need once autogen.sh finishes. Next step is to build libdrm: make and once make finishes successfully, install the package using make install If you are install into a system location, you will need to be root to perform the install step.
