| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kms state itself is already protected by the modeset locks acquired by the drm core. The only thing left is gem bo state, and since the cursor code expects small objects which are statically mapped at create time and then invariant over the lifetime of the gem bo there's nothing to protect. See armada_gem_dumb_create -> armada_gem_linear_back which assigns obj->addr which is the only thing used by the cursor code. Only tricky bit is to switch to the _unlocked unreference function.

| * drm/armada: fix page_flip refcounting leakRussell King2014-10-171-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A refcounting leak was found of the original frame buffer attached to the CRTC when using the page_flip ioctl, resulting in the frame buffer never being freed. This was not obvious initially, as if the page flip subsequently re-attaches the original frame buffer, the refcounts will be balanced. However, if the original frame buffer is freed, then it will be leaked. Fix this by ensuring that we take a reference on the incoming fb, but rely on the queued work to drop that ref count.

* Merge branch 'drm-tda998x-3.12' of ↵Dave Airlie2013-10-221-1/+1
| | | | | | | | | | | | | | | git://ftp.arm.linux.org.uk/~rmk/linux-cubox into drm-next This adds support for the Armada 510 display subsystem found on the Marvell Dove devices. This IP is re-used across several different Marvell SoCs with various tweaks, and this driver has been structured to allow the other IPs to re-use the bulk of this code; further work in this area is expected from interested parties. This has been extensively tested on the SolidRun Cubox platform and appears to work well there. [airlied: update for api changes merged previous to this]

* DRM: Armada: Add Armada DRM driverRussell King2013-10-121-0/+861
This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent.
