drm/vgem: implement virtual GEM

2015-04-01T23:21:48+00:00

This patch implements the virtual GEM driver with PRIME sharing which allows vgem to import a gem object from other drivers for the purpose of mmap-ing them to userspace. The mmap is done using the mmap operation exported by other drivers. v2: remove platform_device and do not attach to dma bufs v3: use drm helpers for get/put pages v4: correct dumb create pitch Reviewed-by: Rob Clark (v3) Reviewed-by: Stéphane Marchesin (v3) Signed-off-by: Adam Jackson Signed-off-by: Ben Widawsky Signed-off-by: Zach Reizner Signed-off-by: Dave Airlie

drm: Kconfig: Let all DRM_GEM_CMA_HELPER related macros depend on HAVE_DMA_ATTRS

DRM_GEM_CMA_HELPER is depend on HAVE_DMA_ATTRS, or it will break the building.

drm/radeon: make MMU_NOTIFIER optional

2015-01-22T15:42:21+00:00

In cases where MMU_NOTIFIER is not available, userptr will not be available. Similar to i915, although not making an exception for CAP_SYS_ADMIN. The proposed userspace patches for userptr seem to handle the fall- back properly, so a userptr-less kernel should not be a problem. Signed-off-by: Rob Clark Signed-off-by: Alex Deucher

drm: add Atmel HLCDC Display Controller support

2015-01-21T08:46:02+00:00

The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display controller device. This display controller supports at least one primary plane and might provide several overlays and an hardware cursor depending on the IP version. At the moment, this driver only implements an RGB connector to interface with LCD panels, but support for other kind of external devices might be added later.

drm: imx: Move imx-drm driver out of staging

2014-11-25T23:40:39+00:00

The imx-drm driver was put into staging mostly for the following reasons, all of which have been addressed or superseded: - convert the irq driver to use linear irq domains - work out the device tree bindings, this lead to the common of_graph bindings being used - factor out common helper functions, this mostly resulted in the component framework and drm of_graph helpers. Before adding new fixes, and certainly before adding new features, move it into its proper place below drivers/gpu/drm. Signed-off-by: Philipp Zabel Signed-off-by: Dave Airlie

So small drm stuff all over for 3.18. Biggest one is the cmdline parsing from Chris with a few fixes from me to make it work for stupid kernel configs. Plus the atomic prep series.
