[Qemu-devel] [Seabios PATCH] make reboot-timeout to static for using it after POST phase

[Amos Kong]

From: Kevin O'Connor <address@hidden>

Memory allocated with malloc_tmp() can't be used after the POST
phase. The reboot-timeout inside romfile could not be loaded in
boot_fail(). The patch saved reboot-timeout to a static variable,
it fixed the regression bug introduced by commit 59d6ca52

I already tested this patch, reboot-timeout parameter of qemu
works now.
@ qemu -boot reboot-timeout=1000 ...
