2015-03-16exynos: add g2d_scale_and_blendTobias Jakobi
This is a combination of g2d_copy_with_scale and g2d_scale. It is a pretty common operation to scale one buffer and then blend it on top of another, so provide a direct way to that operation.

This also avoids the floating point conversion steps and just uses pure integer arithmetic.

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.

2014-06-20exynos: fix scaling factor computation in g2d_copy_with_scaleTobias Jakobi
When division of source and destination width yields the scaling factor for the x-coordinate, then it should be source/destination _height_ for y. Signed-off-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2014-06-20exynos: fix G2D_DOUBLE_TO_FIXED for non-integer inputTobias Jakobi
The hardware accepts scaling factors formatted in a fixed-point format. The current macro casts to integer first, then multiplies by the fp conversion factor. This does not make any sense. In particular, truly 'fractional' inputs, like 1.5, won't work that way. Signed-off-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>

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.
