[PATCH 0/6] media: mediatek: vcodec: support h264 extend vsi
Posted by Yunfei Dong 1 month, 1 week ago
The working buffer address start and end are calculated in kernel
side currently, can't calculate the address end if the driver only
getting the address file handle, not the real physical address. Need
to extend the vsi to calculate the address end in scp.

Re-construct some interface and add config to support extend and non
extend at the same time.

This should be reworked so that "adding non extend struct" is not needed.
"rename vsi to extend vsi" and "extend h264 video share information"
could be combined so that you are "adding" the extended data structures,
not reworking the existing ones. Otherwise the whole thing breaks existing
systems until "adding non extend struct" is applied, making the series
non-bisectable.

Your advice is very reasonable, I will rewrite the patches again.
