[Qemu-devel] [PATCH] Set memory size per machine |
|
Date: |
Sun, 20 Apr 2008 05:33:12 +0200 |
This patch lets a machine decide on the amount of space it'll use in
phys_ram_base in addition to that specified with "-m", default is
zero. Currently that amount was the maximum of BIOS size + VGA RAM
size over all machines of all archs, and that was not enough for the
MusicPal and even if extended it may be not enough for a machine
supported in the future.
This also lets a machine OR the specified value with a RAMSIZE_FIXED
flag to indicate that it ignores the value given with "-m" (true for
almost half of the machines in qemu).
Regards
