Subject: [PATCH] efi: Increase default memory allocation to 32 MiB
|
||
|
|
|
||
|
|
We have multiple reports of things being slower with a 1 MiB initial static
|
||
|
|
allocation, and a report (more difficult to nail down) of a boot failure
|
||
|
|
as a result of the smaller initial allocation.
|
||
|
|
|
||
|
|
Make the initial memory allocation 32 MiB.
