DRM: add DRM Driver for Samsung SoC EXYNOS4210. 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: 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: 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/exynos: added hdmi display support This patch is hdmi display support for exynos drm driver. There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv and some low level code is already in s5p-tv and even headers for register define are almost same. but in this patch, we decide not to consider separated common code with s5p-tv. Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc. 1. mixer. The piece of hardware responsible for mixing and blending multiple data inputs before passing it to an output device. The mixer is capable of handling up to three image layers. One is the output of VP. Other two are images in RGB format. The blending factor, and layers' priority are controlled by mixer's registers. The output is passed to HDMI. 2. vp (video processor). It is used for processing of NV12/NV21 data. An image stored in RAM is accessed by DMA. The output in YCbCr444 format is send to mixer. 3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes pixel data from mixer and transforms it into data frames. The output is send to HDMIPHY interface. 4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to HDMI connector. Basically, it contains a PLL that produces source clock for mixer, vp and hdmi. 5. ddc (display data channel). It is dedicated i2c channel to exchange display information as edid with display monitor. With plane support, exynos hdmi driver fully supports two mixer layes and vp layer. Also vp layer supports multi buffer plane pixel formats having non contigus memory spaces. In exynos drm driver, common drm_hdmi driver to interface with drm framework has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls them. mixer controls all overlay layers in both mixer and vp. Vblank interrupts for hdmi are handled by mixer internally because drm framework cannot support multiple irq id. And pipe number is used to check which display device irq happens.

drm/exynos: add G2D driver Changelog v3: - use __u64 instead of pointer in ioctl struct. The G2D is a 2D graphic accelerator that supports Bit Block Transfer. This G2D driver is exynos drm specific and supports only G2D(version 4.1) of later Exynos series from Exynos4X12 because supporting DMA. The G2D is performed by two tasks simply. 1. Configures the rendering parameters, such as foreground color and coordinates data by setting the drawing context registers. 2. Start the rendering process by setting thre relevant command registers accordingly. The G2D version 4.1 supports DMA mode as host interface. User can make command list to reduce HOST(ARM) loads. The contents of The command list is setted to relevant registers of G2D by DMA. The command list is composed Header and command sets and Tail. - Header: The number of command set(4Bytes) - Command set: Register offset(4Bytes) + Register data(4Bytes) - Tail: Pointer of base address of the other command list(4Bytes) By Tail field, the G2D can process many command lists without halt at one go. The G2D has following the rendering pipeline. --> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling --> Color Key --> ROP --> Mask Operation --> Alpha Blending --> Dithering --> FrameBuffer And supports various operations from the rendering pipeline. - copy - fast solid color fill - window clipping - rotation - flip - 4 operand raster operation(ROP4) - masking operation - alpha blending - color key - dithering - etc User should make the command list to data and registers needed by operation to use. The Exynos G2D driver only manages the command lists received from user. Some registers needs memory base address(physical address) of image. User doesn't know its physical address, so fills the gem handle of that memory than address to command sets, then G2D driver converts it to memory base address. We adds three ioctls and one event for Exynos G2D. - ioctls DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver - event DRM_EXYNOS_G2D_EVENT: event to give notification completion of the command list to user Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

drm/exynos: add G2D driver Changelog v3: - use __u64 instead of pointer in ioctl struct. The G2D is a 2D graphic accelerator that supports Bit Block Transfer. This G2D driver is exynos drm specific and supports only G2D(version 4.1) of later Exynos series from Exynos4X12 because supporting DMA. The G2D is performed by two tasks simply. 1. Configures the rendering parameters, such as foreground color and coordinates data by setting the drawing context registers. 2. Start the rendering process by setting thre relevant command registers accordingly. The G2D version 4.1 supports DMA mode as host interface. User can make command list to reduce HOST(ARM) loads. The contents of The command list is setted to relevant registers of G2D by DMA. The command list is composed Header and command sets and Tail. - Header: The number of command set(4Bytes) - Command set: Register offset(4Bytes) + Register data(4Bytes) - Tail: Pointer of base address of the other command list(4Bytes) By Tail field, the G2D can process many command lists without halt at one go. The G2D has following the rendering pipeline. --> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling --> Color Key --> ROP --> Mask Operation --> Alpha Blending --> Dithering --> FrameBuffer And supports various operations from the rendering pipeline. - copy - fast solid color fill - window clipping - rotation - flip - 4 operand raster operation(ROP4) - masking operation - alpha blending - color key - dithering - etc User should make the command list to data and registers needed by operation to use. The Exynos G2D driver only manages the command lists received from user. Some registers needs memory base address(physical address) of image. User doesn't know its physical address, so fills the gem handle of that memory than address to command sets, then G2D driver converts it to memory base address.
