drm/exynos: update exynos_drm_framebuffer_init() for multiple buffers

2015-09-02T14:10:32Z

This modifies exynos_drm_framebuffer_init() to be possible to support multiple buffers. Then it can be used by exynos_user_fb_create(). Signed-off-by: Joonyoung Shim Signed-off-by: Inki Dae

drm/exynos: update fb_info via only one function

2015-09-02T14:10:31Z

This patch moves codes to update fb_info into exynos_drm_fbdev_update(), so fb_info is updated via only one function. Signed-off-by: Joonyoung Shim Reviewed-by: Gustavo Padovan Signed-off-by: Inki Dae

drm/exynos: cleanup exynos_drm_fbdev_update()

2015-09-02T14:10:30Z

It can get exynos_gem object via function argument, so no need to call exynos_drm_fb_gem_obj() in exynos_drm_fbdev_update. It also can get struct drm_framebuffer *fb via helper->fb, so can remove a function argument for it. Signed-off-by: Joonyoung Shim Reviewed-by: Gustavo Padovan Signed-off-by: Inki Dae

drm/exynos: s/exynos_gem_obj/obj in exynos_drm_fbdev.c

2015-09-02T14:10:30Z

The variable name "exynos_gem_obj" is too long, so some lines exceed 80 characters. It's simple to use "obj" instead of "exynos_gem_obj". Signed-off-by: Joonyoung Shim Reviewed-by: Gustavo Padovan Signed-off-by: Inki Dae

drm/exynos: remove exynos_drm_fb_set_buf_cnt()

2015-09-02T14:10:30Z

The exynos_drm_fb_set_buf_cnt() is used to set buffer count only in exynos_drm_fbdev_update(). This patch sets directly buffer count in exynos_drm_framebuffer_init() without using exynos_drm_fb_set_buf_cnt(), so there is no any reason to keep exynos_drm_fb_set_buf_cnt().

drm/exynos: merge exynos_drm_buf.c to exynos_drm_gem.c

2015-08-16T05:39:32Z

The struct exynos_drm_gem_obj can have fields of the struct exynos_drm_gem_buf then don't need to use exynos_drm_buf.c file. Signed-off-by: Joonyoung Shim Signed-off-by: Inki Dae

drm/exynos: Use new drm_fb_helper functions

2015-08-06T12:12:58Z

Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation. v2: - Remove unnecessary dealloc cmap in error handling path Cc: Inki Dae Cc: Joonyoung Shim Cc: Seung-Woo Kim Signed-off-by: Archit Taneja Signed-off-by: Daniel Vetter

drm/exynos: don't disable unused functions at init

2015-06-19T15:32:49Z

Everything starts disabled so we don't really need to disable anything. Signed-off-by: Gustavo Padovan Reviewed-by: Joonyoung Shim Tested-by: Tobias Jakobi Signed-off-by: Inki Dae

drm/exynos: use correct fb width/height

2015-03-11T21:08:17Z

What is passed to drm_fb_helper_fill_var() should be fb_width/fb_height, rather than the surface size. Signed-off-by: Rob Clark Reviewed-by: Alex Deucher Acked-by: Laurent Pinchart Signed-off-by: Daniel Vetter

drm/exynos: fix DMA_ATTR_NO_KERNEL_MAPPING usage

2015-02-07T07:38:41Z

The Exynos DRM driver doesn't follow the correct API when dealing with dma_{alloc, mmap, free}_attrs functions and the DMA_ATTR_NO_KERNEL_MAPPING attribute. When a IOMMU is not available and the DMA_ATTR_NO_KERNEL_MAPPING is used, the driver should use the pointer returned by dma_alloc_attr() as a cookie. The Exynos DRM driver directly uses the non-requested virtual kernel address returned by the DMA mapping subsystem. This just works now because the non-IOMMU codepath doesn't obey DMA_ATTR_NO_KERNEL_MAPPING but we need to fix it before fixing the DMA layer.
