2015-04-28drm: remove drm_public macroEmil Velikov
Some compilers (like the Oracle Studio), require that the function declaration must be annotated with the same visibility attribute as the definition. As annotating functions with drm_public is no longer required just remove the macro.

2015-04-28drm: remove no longer needed VISIBILITY_CFLAGSEmil Velikov
With earlier commits we've annotated the private symbols, thus we no longer require the -fvisibility=hidden CFLAGS.

2015-03-16exynos: honor the repeat mode in g2d_copy_with_scaleTobias Jakobi
This is useful when the default repeat mode, which is 'repeat' produces artifacts at the borders of the copied image. Choose the 'pad' mode to make use of the color of the destination image. In my usage case the destination is the framebuffer, which is solid filled with a background color. Scaling with 'pad' mode would then just do the right thing and also produces nice borders on the output.

2015-02-02exynos: Don't use DRM_EXYNOS_GEM_{MAP_OFFSET/MMAP} ioctlsHyungwon Hwang
The ioctl DRM_EXYNOS_GEM_MAP_OFFSET and DRM_EXYNOS_GEM_MMAP are removed from the linux kernel. This patch modifies libdrm and libkms to use drm generic ioctls instead of the removed ioctls. v2: The original patch was erroneous. In case the MODE_MAP_DUMB ioctl failed it would return the retvalue as a void-pointer. Users of libdrm would then happily use that ptr, eventually leading to a segfault. Change this to return NULL in that case and also restore the previous behaviour of logging to stderr. The other error was that 'bo->vaddr' was never filled with the mapped buffer address. Hence exynos_bo_map still returned NULL even if the buffer mapping succeeded.

2013-03-08libdrm/exynos: add test application for 2d gpu.Inki Dae
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.
