[libcamera-devel] [PATCH v3 0/5] Raspberry Pi: Efficient start/stop/start sequences

[Naushir Patuck]

Hi,

For version 3 of this series, I've removed the patch to add a timer that waits
for 5s after stop() to de-allocate buffers.  David and me have had a chat about
this and we think for now it is best that we have fully deterministic behavior for
buffer allocations, and avoid CMA fragmentation on the Raspberry Pi platforms.
Apart from that, I have renamed the reallocate flag based on Kieran's suggestion.

Regards,
Naush
