Add feature to gbm_gralloc and drm_hwcomposer HALs that will search for KMS DRI card #31

Closed rsglobal closed 4 years ago

rsglobal commented 4 years ago

We can not always guarantee that KMS card will always have /dev/dri/card0 path, This path can depend on different factors, e.g. DTS node order, driver compiled as a module or built-in, etc. Both drm_hwcomposer and gbm_gralloc have to always use KMS driver, not GPU.

@matviizorin ,

I've just found same algorithm in libkmsxx: https://github.com/tomba/kmsxx/blob/d9d5e44526a3b8065e4ae913032020d0bfd93103/kms%2B%2B/src/card.cpp#L42

So it should save hours of your efforts.
