I think, the key idea is just to support the default for qxl (128Mib) in the discussion. videoram is not designed for qxl video ram. > If we reject values which are <128M, and clamp anything which is >128M > to 128M then what is the point of the option? This piece of code doesn't mean to use videoram option to assign memory for qxl. Because videoram option comes in Xen before qxl, it need to be consided here. v2 gives user the chance to assign memory for qxl. > > Ian. -- Zhou Peng _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
