We saw that patches [1] and [2] cause issue on stable version (at least for
5.4). As you said issue can be seen with above device tree and check in
/proc/iomem than gpu_reserved region is taken by the kernel as "System RAM".
On v5.10 stream there are no issues seen taking patches [1]&[2] and the
reason is linked to patches [3]&[4] which have been introduced in v5.10.0.
Reverting them give me the same behavior than on stable version.
Thanks for confirming. Given that the patches were not really fixes, I
think reverting is still the best option. I've sent reverts to -stable
for 5.4 and prior:
