Subject: [PATCH 0036/1085] drm/vc4: Set AXI panic modes for the HVS
|
|
|
|
The HVS can change AXI request mode based on how full the COB
|
|
FIFOs are.
|
|
Until now the vc4 driver has been relying on the firmware to
|
|
have set these to sensible values.
|
|
|
|
With HVS channel 2 now being used for live video, change the
|
|
panic mode for all channels to be explicitly set by the driver,
|
|
and the same for all channels.
