Add gbm_client as generic backend to minigbm #57

Closed rsglobal closed 3 years ago

rsglobal commented 4 years ago

gbm_gralloc pros:

Simplicity
Ability to use any GPU+Display Controller combination which is supported by mesa3d

gbm_gralloc cons:

Only gralloc2.0 API is implemented.
gbm_gralloc has almost no active community support for a long time.
No advanced allocation support (Compressed buffers for scanout,, etc.)
Poor video format-set support

minigbm pros:

gralloc4 API available (EGL api, HWComposer HALs can now rely only on gralloc4 metadata API)
ChromeOS community support

minigbm cons:

New backends should be implemented and supported
Generic backend / inheritance is not available
