[Mesa-dev] [PATCH v2 0/9] GBM map/unmap support

[Rob Herring]

This series adds map and unmap functions to GBM. These are needed to
provide a device independent buffer allocation interface to Android's
gralloc.

Open questions:
- Need to flush context on unmap?
- Need fences for gralloc lockAsync support?

Major changes from v1[1]:
- Further split up patches
- Make READ flag optional
- Move context creation to GBM map function
- Improve documentation comments

Major changes from RFC[2]:
- Split up patches
- Consistently use map instead of lock for function names
- Clean up and propogate mapping usage flags
- Add extension version checking
- Add returned stride for mapped buffer
- Got rid of pipe_private ptr passing it back to caller instead
- Move context creation to gbm_device_create and add destroyContext call
- Add/fix function comments
