From: Stefano Stabellini Date: Mon, 3 Aug 2009 15:14:39 +0000 (+0100) Subject: vga: do not resize the screen on hw_invalidate X-Git-Tag: v0.11.0-rc2~17 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=141bc15f548c19af086509a259f58b306b92be8f;p=thirdparty%2Fqemu.git vga: do not resize the screen on hw_invalidate Hi all, currently vga always resizes the screen when vga_hw_invalidate is called while this is not required and all the other graphic emulators don't. This patch fixes it, making vga invalidate behaviour consistent with the other emulated devices.
