A DRM display driver for TI OMAP platform. Similar to omapfb (fbdev) and omap_vout (v4l2 display) drivers in the past, this driver uses the DSS2 driver to access the display hardware, including support for HDMI, DVI, and various types of LCD panels. And it implements GEM support for buffer allocation (for KMS as well as offscreen buffers used by the xf86-video-omap userspace xorg driver). The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's. Note that this arrangement might change slightly when support for drm_plane overlays is added. For GEM support, non-scanout buffers are using the shmem backed pages provided by GEM core (In drm_gem_object_init()). In the case of scanout buffers, which need to be physically contiguous, those are allocated with CMA and use drm_gem_private_object_init(). See userspace xorg driver: git://github.com/robclark/xf86-video-omap.git Refer to this link for CMA (Continuous Memory Allocator): http://lkml.org/lkml/2011/8/19/302 Links to previous versions of the patch: v1: http://lwn.net/Articles/458137/ v2: http://patches.linaro.org/4156/ v3: http://patches.linaro.org/4688/ v4: http://patches.linaro.org/4791/ History: v5: move headers from include/drm at Greg KH's request, minor rebasing on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages() because "drm/gem: add functions to get/put pages" patch is not merged yet v4: bit of rework of encoder/connector _dpms() code, modeset_init() rework to not use nested functions, update TODO.txt v3: minor cleanups, improved error handling for dev_load(), some minor API changes that will be needed later for tiled buffer support v2: replace omap_vram with CMA for scanout buffer allocation, remove unneeded functions, use dma_addr_t for physical addresses, error handling cleanup, refactor attach/detach pages into common drm functions, split non-userspace-facing API into omap_priv.h, remove plugin API v1: original Signed-off-by: Rob Clark <rob@ti.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This option allows you to select a number of drivers that are
|
|
not of the "normal" Linux kernel quality level. These drivers
|
|
are placed here in order to get a wider audience to make use of
|
|
them. Please note that these drivers are under heavy
|
|
development, may or may not work, and may contain userspace
|
|
interfaces that most likely will be changed in the near
|
|
future.
|
|
|
|
Using any of these drivers will taint your kernel which might
|
|
affect support options from both the community, and various
|
|
commercial support organizations.
|
|
|
|
If you wish to work on these drivers, to help improve them, or
|
|
to report problems you have with them, please see the
|
|
driver_name.README file in the drivers/staging/ directory to
|
|
see what needs to be worked on, and who to contact.
|
|
|
|
If in doubt, say N here.
