2016-05-17drm: Remove unused drm_device from drm_gem_object_lookup()Chris Wilson1-2/+1
drm_gem_object_lookup() has never required the drm_device for its file local translation of the user handle to the GEM object. Let's remove the unused parameter and save some space.

Struct of gem object in exynos_drm driver is struct exynos_drm_gem_obj. It's too long and we can know its meaning of name without _obj postfix. We use several names to variable name of gem object for exynos_drm - exynos_gem_obj, gem_obj and obj. Especially "obj" name can cause misunderstanding with variable name "obj" of struct drm_gem_object.

Looking other drm drivers, there is no the restriction that framebuffer has only one buffer in .create_handle() callback. They use just first buffer.

2015-06-20drm/exynos: do not wait for vblank at atomic operationInki Dae1-2/+0
This patch resolves the issue that refresh rate got low at extension mode test with fimd and vidi combination.

2015-05-19drm/exynos: fb: use drm_format_num_planes to get buffer countTobias Jakobi1-38/+1
The previous code had some special case handling for the buffer count in exynos_drm_format_num_buffers(). This code was incorrect though, since this special case doesn't exist for DRM. It stemmed from the existence of the special NV12M V4L2 format. NV12 is a bi-planar format (separate planes for luma and chroma) and V4L2 differentiates between a NV12 buffer where luma and chroma is contiguous in memory (so no data between luma/chroma), and a NV12 buffer where luma and chroma have two explicit memory locations (which is then called NV12M). This distinction doesn't exist for DRM. A bi-planar format always explicitly comes with the information about its two planes (even if these planes should be contiguous).

2012-12-05drm/exynos: make sure that overlay data are updatedInki Dae1-0/+4
Changelog v2: fix a little bit performance issue to previous patch. - When drm framebuffer is destroyed, make sure that overlay data are updated to real hardwrae for all encoders instead of waiting for vblank every page flip request. For this, it adds a new function, exynos_drm_encoder_complete_scanout function. Changelog v1: This patch removes wait_for_vblank call from exynos_drm_encoder_plane_disable function and move it to exynos_drm_encoder_plane_commit function. Disabling dma channel to each plane doens't need vblank signal to update data to real hardware. But updating overlay data to real hardware does need vblank signal.

Changelog v2: - fix iommu attach condition. . check archdata.dma_ops of drm device instead of subdrv device's one. - code clean to exynos_drm_iommu.c file. . remove '#ifdef CONFIG_ARM_DMA_USE_IOMMU' from exynos_drm_iommu.c and add it to driver/gpu/drm/exynos/Kconfig. Changelog v1: This patch adds iommu support for exynos drm framework with dma mapping api. In this patch, we used dma mapping api to allocate physical memory and maps it with iommu table and removed some existing codes and added new some codes for iommu support. GEM allocation requires one device object to use dma mapping api so this patch uses one iommu mapping for all sub drivers. In other words, all sub drivers have same iommu mapping.

2011-10-05DRM: add DRM Driver for Samsung SoC EXYNOS4210.Inki Dae1-0/+271
This patch is a DRM Driver for Samsung SoC Exynos4210 and now enables only FIMD yet but we will add HDMI support also in the future. this patch is based on git repository below: git://people.freedesktop.org/~airlied/linux.git branch name: drm-next commit-id: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67 you can refer to our working repository below: http://git.infradead.org/users/kmpark/linux-2.6-samsung branch name: samsung-drm We tried to re-use lowlevel codes of the FIMD driver(s3c-fb.c based on Linux framebuffer) but couldn't so because lowlevel codes of s3c-fb.c are included internally and so FIMD module of this driver has its own lowlevel codes. We used GEM framework for buffer management and DMA APIs(dma_alloc_*) for buffer allocation so we can allocate physically continuous memory for DMA through it and also we could use CMA later if CMA is applied to mainline. Refer to this link for CMA(Continuous Memory Allocator): http://lkml.org/lkml/2011/7/20/45 this driver supports only physically continuous memory(non-iommu).

DRM: code clean and add exception codes. Changelog v3: DRM: Support multiple irq. FIMD and HDMI have their own irq handler but DRM Framework can regiter only one irq handler this patch supports mutiple irq for Samsung SoC. DRM: Consider modularization. each DRM, FIMD could be built as a module. DRM: Have indenpendent crtc object. crtc isn't specific to SoC Platform so this patch gets a crtc to be used as common object. created crtc could be attached to any encoder object. DRM: code clean and add exception codes. Changelog v4: DRM: remove is_defult from samsung_fb. is_default isn't used for default framebuffer. DRM: code refactoring to fimd module. this patch is be considered with multiple display objects and would use its own request_irq() to register a irq handler instead of drm framework's one. DRM: remove find_samsung_drm_gem_object() DRM: move kernel private data structures and definitions to driver folder. samsung_drm.h would contain only public information for userspace ioctl interface. DRM: code refactoring to gem modules. buffer module isn't dependent of gem module anymore. DRM: fixed security issue. DRM: remove encoder porinter from specific connector. samsung connector doesn't need to have generic encoder. DRM: code clean and add exception codes. Changelog v5: DRM: updated fimd(display controller) driver. added various pixel formats, color key and pixel blending features. DRM: removed end_buf_off from samsung_drm_overlay structure. this variable isn't used and end buffer address would be calculated by each sub driver. DRM: use generic function for mmap_offset. replaced samsung_drm_gem_create_mmap_offset() and samsung_drm_free_mmap_offset() with generic ones applied to mainline recentrly. DRM: removed unnecessary codes and added exception codes. DRM: added comments and code clean. Changelog v6: DRM: added default config options. DRM: added padding for 64-bit align. DRM: changed prefix 'samsung' to 'exynos' Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Seung-Woo Kim <sw0312.kim@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
