Subject: [PATCH v1 2/2] um: increase default virtual physical memory to 64 MiB

The current 32 MiB of RAM causes OOMs to appear shortly after
|
||
|
|
booting in a minimal OpenWrt 22.03 configuration with a
|
||
|
|
5.10.134 kernel.
|
||
|
|
|
||
|
|
Of course, passing a "mem=64M" (from the --help text) parameter
|
||
|
|
works too, but it produces the following (info) message:
|
||
|
|
|
||
|
|
| [ 0.000000] Unknown kernel command line parameters "mem=64M", will be passed to user space.
|
||
|
|
|
||
|
|
That's why, I think it would be nicer, if this is working out
|
||
|
|
of the box again :).
