Since the introduction of XSERVER_LIBPCIACCESS BIOS reading is broken on some hardware (SIS_650, SIS_760, maybe others) causing severe color corruption. This is a proposed fix.
Xorg bug: https://bugs.freedesktop.org/show_bug.cgi?id=19070 Related launchpad bug: https://bugs.launchpad.net/xorg-server/+bug/264769 xf86-video-sis commit switching bios reading to libpciaccess: http://cgit.freedesktop.org/xorg/driver/xf86-video-sis/commit/?id=585e03e6878dd257c694517be9ea231a6b3cfb66 Signed-off-by: Matteo Delfino <kendats...@gmail.com> --- Apparently a small amount of code in the bios reading routine is skipped if XSERVER_LIBPCIACCESS is detected. In version 0.9.4 that portion of code is supposed to read the card BIOS using xf86ReadBIOS (or xf86ReadDomainMemory) if xf86ReadPciBIOS has failed or readpci=FALSE. It seems that for SIS_660 and SIS_760 readpci is set to FALSE resulting in the following error using versions > 0.9.4: (WW) SIS(0): Could not find/read video BIOS This fix forces readpci = TRUE for SIS_660 and SIS_760, I don't know if that's correct but applying the patch solves the problem. src/sis_driver.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/src/sis_driver.c b/src/sis_driver.c index 994b02d..b19e7a9 100644 --- a/src/sis_driver.c +++ b/src/sis_driver.c @@ -4099,6 +4099,8 @@ SISPreInit(ScrnInfoPtr pScrn, int flags) case SIS_315H: case SIS_330: case SIS_340: + case SIS_650: + case SIS_760: case XGI_40: readpci = TRUE; break; case XGI_20: readpci = TRUE; -- 1.6.3.3 _______________________________________________ xorg-devel mailing list xorg-devel@lists.x.org http://lists.x.org/mailman/listinfo/xorg-devel
