2015-07-16freedreno: zero is a valid fd number, treat it as suchEmil Velikov
Abeit quite unlikely to get hit by this bug here, let just fix it. v2: Correct conditional (do not call ioctl(DRM_IOCTL_PRIME_HANDLE_TO_FD) when we already have the fd). v3: Fix kgsl_pipe.c, suggested by Thierry.

2015-04-28drm: remove drm_public macroEmil Velikov
Some compilers (like the Oracle Studio), require that the function declaration must be annotated with the same visibility attribute as the definition. As annotating functions with drm_public is no longer required just remove the macro.

2015-04-28freedreno: annotate the private symbolsEmil Velikov
They are less and easier to track than the public ones. The macro drm_public will be going away by the end of the series. Cc: Rob Clark <robdclark@gmail.com> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>

Userspace needs to know the patch-revision in addition to just the gpu-id (ie. 320, 305, etc). Signed-off-by: Rob Clark <robclark@freedesktop.org>
2014-03-05freedreno/kgsl: don't even bother trying CREATE_FDRob Clark
Don't even bother trying DRM_KGSL_GEM_CREATE_FD. It hasn't worked since (afaict) 2.6.35 kernels. And in some cases seems to cause some problems. Instead just allocate a minimum size dummy object (just for purposes of having a handle) and then mmap the framebuffer as user-mem (which is deprecated, but seems to still work.. and as far as I can tell is the best option for now).

2013-12-13freedreno: add bo cacheRob Clark
Workloads which create many transient buffers cause significant CPU overhead in buffer allocation, zeroing, cache maint, and mmap setup. By caching and re-using existing buffers, the CPU overhead drops significantly. See: http://bloggingthemonkey.blogspot.com/2013/09/freedreno-update-moar-fps.html A simple time based policy is used for purging the cache. Once the kernel supports it, we could use madvise style API to handle memory pressure scenarios a bit better. Signed-off-by: Rob Clark <robclark@freedesktop.org>

Split out common code and backend. Current backend is for 'kgsl' android driver, but a new backend will provide support for the upstream msm drm/kms driver. Signed-off-by: Rob Clark <robclark@freedesktop.org>
