drm: only build ati_pcigart if PCI enabled

2012-11-28T10:12:29Z

Prevent ati_pcigart.c being built unless PCI is enabled. The exported functions in this file are only used by drivers which depend on PCI (namely r128 and radeon), and it tries to use PCI specific functions (pci_unmap_page, pci_map_page, and pci_dma_mapping_error) that cause compiler errors when PCI is disabled.

drm: Add NVIDIA Tegra20 support

2012-11-20T05:43:41Z

This commit adds a KMS driver for the Tegra20 SoC. This includes basic support for host1x and the two display controllers found on the Tegra20 SoC. Each display controller can drive a separate RGB/LVDS output.

drm: rename drm_dp_i2c_helper.c to drm_dp_helper.c

2012-10-22T20:20:31Z

I want to move some dp link training helpers into this place, so in the future this won't be just about i2c any longer. Reviewed-by: Alex Deucher Acked-by: Dave Airlie Signed-off-by: Daniel Vetter

drm: Renesas SH Mobile DRM driver

2012-09-18T10:28:22Z

The SH Mobile LCD controller (LCDC) DRM driver supports the main graphics plane in RGB and YUV formats, as well as the overlay planes (in alpha-blending mode only). Only flat panel outputs using the parallel interface are supported. Support for SYS panels, HDMI and DSI is currently not implemented. Signed-off-by: Laurent Pinchart Reviewed-by: Sascha Hauer

DRM: Add DRM KMS/FB CMA helper

2012-09-18T10:28:21Z

DRM: Add DRM GEM CMA helper

2012-09-18T10:28:21Z

Many embedded drm devices do not have a IOMMU and no dedicated memory for graphics. These devices use CMA (Contiguous Memory Allocator) backed graphics memory. This patch provides helper functions to be able to share the code. The code technically does not depend on CMA as the backend allocator, the name has been chosen because CMA makes for a nice, short but still descriptive function prefix.

drm/kms: driver for virtual cirrus under qemu

2012-05-17T10:02:24Z

This is the initial driver for emulated cirrus GPU found in qemu. This driver only supports the emulated GPU and doesn't attempt to bind to any real cirrus GPUs. This driver is intended to be used with xf86-video-modesetting in userspace. It requires at least version 0.3.0 This follow the same design as ast and mgag200, and is based on work done by Matthew Garrett previously. This GPU has no hw cursor, and it can't scanout 32-bpp, only packed 24-bpp. i.e. it sucks. Reviewed-by: Adam Jackson Signed-off-by: Dave Airlie

mgag200: initial g200se driver (v2)

2012-05-17T09:53:41Z

This is a driver for the G200 server engines chips, it doesn't driver any of the Matrix G series desktop cards. It will bind to G200 SE A,B, G200EV, G200WB, G200EH and G200ER cards. Its based on previous work done my Matthew Garrett but remodelled to follow the same style and flow as the AST server driver. It also works along the same lines as the AST server driver wrt memory management. There is no userspace driver planned, xf86-video-modesetting should be used. It also appears these GPUs have no ARGB hw cursors. v2: add missing tagfifo reset + G200 SE memory bw setup pieces. Signed-off-by: Dave Airlie

drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)

2012-05-17T09:53:37Z

This is the initial driver for the Aspeed Technologies chips found in servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It doesn't support the AST11xx due to lack of hw to test it on, and them requiring different codepaths. This driver is intended to be used with xf86-video-modesetting in userspace. This driver has a slightly different design than other KMS drivers, but future server chips will probably share similiar setup. As these GPUs commonly have low video RAM, it doesn't make sense to put the kms console in VRAM always. This driver places the kms console into system RAM, and does dirty updates to a copy in video RAM. When userspace sets a new scanout buffer, it forcefully evicts the video RAM console, and X can create a framebuffer that can use all of of video RAM. This driver uses TTM but in a very simple fashion to control the eviction to system RAM of the console, and multiple servers. v2: add s/r support, fix Kconfig. Signed-off-by: Dave Airlie

drm: base prime/dma-buf support (v5)

2012-03-30T10:52:44Z

This adds the basic drm dma-buf interface layer, called PRIME. This commit doesn't add any driver support, it is simply and agreed upon starting point so we can work towards merging driver support for the next merge window. Current drivers with work done are nouveau, i915, udl, exynos and omap. The main APIs exposed to userspace allow translating a 32-bit object handle to a file descriptor, and a file descriptor to a 32-bit object handle. The flags value is currently limited to O_CLOEXEC. Acknowledgements: Daniel Vetter: lots of review Rob Clark: cleaned up lots of the internals and did lifetime review. v2: rename some functions after Chris preferred a green shed fix IS_ERR_OR_NULL -> IS_ERR v3: Fix Ville pointed out using buffer + kmalloc v4: add locking as per ickle review v5: allow re-exporting the original dma-buf (Daniel) Reviewed-by: Daniel Vetter Reviewed-by: Rob Clark Reviewed-by: Sumit Semwal Reviewed-by: Inki Dae Acked-by: Ben Widawsky Signed-off-by: Dave Airlie
