Parent article: Airlie: raspberry pi drivers are NOT useful
the question is if the stability issues are due to the driver, or due to the driver's interaction with the rest of the kernel.
A distinction without a difference. The driver has no purpose and no function other than inside the kernel.
If stuff running on the GPU limits itself to reading and writing buffers that are explicitly allocated for it, almost all of the problems mentioned go away, and the remaining 'shim' driver can evolve along with the rest of the kernel.
But as long as the stuff running on the GPU is an opaque blob we cannot audit or replace there is absolutely no way we can ever have any confidence that it is limited like that.
