      staging: add omapdrm DRM/KMS driver for TI OMAP platforms · cd5351f4
      由 Rob Clark 提交于 
      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:

Refer to this link for CMA (Continuous Memory Allocator):

v2: http://patches.linaro.org/4156/

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

      Staging: delete spectra driver · be7f39c5
      由 Greg Kroah-Hartman 提交于 
      To quote Alan:
	Moorestown/Oaktrail has appeared only in the PC like form so the
	following bits of staging can be binned:

	drivers/staging/spectra

so let's delete it.

      staging: gma500: Intel GMA500 staging driver · 0867b421
      由 Alan Cox 提交于 
      This is an initial staging driver for the GMA500. It's been stripped out
of the PVR drivers and crunched together from various bits of code and
different kernels.

Currently it's unaccelerated but still pretty snappy even compositing with
the frame buffer X server.

Lots of work is needed to rework the ttm and bo interfaces from being
ripped out and then 2D acceleration wants putting back for framebuffer and
somehow eventually via DRM.

There is no support for the parts without open source userspace (video
accelerators, 3D) as per kernel policy.
