From 0bd8246bfec1dfb2eb959f52db535572c0260f4c Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Mon, 3 Aug 2009 16:14:39 +0100 Subject: [PATCH] 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.
