Subject: [PATCH] overlays: Reduce Pi 4 vc4 CMA size to 320MB
|
|
|
|
Reduce the default CMA allocation requested by the vc4-kms-v3d-pi4 and
|
|
vc4-fkms-v3d-pi4 overlays to 320MB.
|
|
|
|
Use magic values of the form (<n>*64 - 4)MB to encode default values
|
|
of <n>*64MB, allowing these defaults to be distinguished from values
|
|
set explicitly by the user with the usual overlay parameters (e.g.
|
|
"cma-384"). Only default values will be capped if the Pi RAM is too
|
|
small or the gpu_mem setting too large for it to be viable.
