From 444984a578aae92ff55c06da897ea1d23679e706 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Thu, 21 Feb 2008 08:37:42 -0800 Subject: [PATCH] Remove side effects from VGA debug code The VGA register dumping code was leaving ARX in data mode rather than index mode, which could cause problems for later software accessing AR* registers. Fix it to make sure it's in index mode when we're done. Fixes #14434. --- src/i830_debug.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/i830_debug.c b/src/i830_debug.c index 09ec5099..7d0c0a0c 100644 --- a/src/i830_debug.c +++ b/src/i830_debug.c @@ -734,6 +734,7 @@ static void i830DumpAR(ScrnInfoPtr pScrn) } INREG8(st01); OUTREG8(0x3c0, orig_arx); + INREG8(st01); /* switch back to index mode */ } void i830DumpRegs (ScrnInfoPtr pScrn)
