Subject: [PATCH 1/2] ieee1275: Further increase initially allocated heap from
|
||
|
|
1/3 to 1/2
|
||
|
|
|
||
|
|
The memory increase to 1/3 of 391MB (~127MB) was still insufficient
|
||
|
|
to boot the kernel and initrd of the SuSE distribution:
|
||
|
|
|
||
|
|
initrd 2023-Jan-18 04:27 114.9M
|
||
|
|
linux 2023-Jan-17 05:23 45.9M
|
||
|
|
|
||
|
|
Therefore, further increase the initially allocated heap to 1/2
|
||
|
|
of 391MB to ~191MB, which now allows to boot the system from an
|
||
|
|
ISO.
