Subject: [PATCH] gpu: vc4-fkms: Switch to the newer mailbox frame
|
|
buffer API.
|
|
|
|
The old mailbox FB API was ideally deprecated but still used by
|
|
the FKMS driver.
|
|
Update to the newer API.
|
|
|
|
NB This needs current firmware that accepts ARM allocated buffers
|
|
through the newer API.
