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.

2012-05-12libdrm: add exynos drm supportInki Dae
this patch adds libdrm_exynos helper layer that inclues some intefaces for exynos specific gem and virtual display driver and also adds exynos module name to modtest and vbltest. Changelog v2: - fixed exynos broken ioctl. the pointer of uint64_t *edid should be removed. - removed unnecessary definitions. - added drm prime interfaces. this feature is used to share a buffer between drivers or memory managers and for this, please, refer to below links: http://www.mjmwired.net/kernel/Documentation/dma-buf-sharing.txt http://lwn.net/Articles/488664/ this patch is based on a link below: git://anongit.freedesktop.org/mesa/drm commit id: d72a44c7c4f5eea9c1e5bb0c36cb9e0224b9ca22 Reviewed-by: Rob Clark <rob@ti.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Rob Clark <rob@ti.com>
