[PATCH V2 1/6] qemu: Remove vram attribute in some cases

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Zeng Junliang <zengjunliang@xxxxxxxxxx>

The vram attribute is invalid for cirrus and stdvga
device, and default vram value would make us confused.
It would be better to remove it.
