Subject: [PATCH 0589/1085] drm/vc4: hvs: Test if the EOF interrupts are
|
|
enabled
|
|
|
|
We currently enable the EOF interrupts through the CRTC destroy_state
|
|
implementation.
|
|
|
|
However, nothing guarantees that we can't call destroy_state multiple
|
|
times in a row, and therefore before the EOF interrupt even happens.
|
|
|
|
This means we would enable the interrupt multiple times but disable it
|
|
only once. It wasn't an issue so far since the interrupts were only
|
|
enabled by setting a bit in a register, but with BCM2712 we will use an
|
|
external interrupt controller, with a refcounted interrupt.
