The following reply was made to PR kern/108582; it has been noted by GNATS. From: "Chris Billington" <cbillington@emulti.net> To: bug-followup@freebsd.org, billington.chris@gmail.com Cc: Subject: Re: kern/108582: [agp] White square cursor i915 DRI Xorg 6.9.0 AGP Date: Wed, 21 Feb 2007 00:39:32 +0100 Chasing these errors: %grep ALLOC /var/log/Xorg.0.log (WW) ****INVALID MEM ALLOCATION**** b: 0xffe80000 e: 0xffefffff correcti= ng (WW) ****INVALID MEM ALLOCATION**** b: 0xffe40000 e: 0xffe7ffff correcti= ng A slightly dirty hack has fixed this problem. I followed the suggestion at = http://leaf.dragonflybsd.org/mailarchive/users/2006-12/msg00109.html By removing the new lines in the RemoveOverlaps code since version 1.3 o= f = xorg 6.9.0 xf86.c, that is reverting to the old 6.8.2 version of the = overlap removal code: http://webcvs.freedesktop.org/xorg/xc/programs/Xserver/hw/xfree86/common= /xf86Bus.c?r1=3D1.3&r2=3D1.8 Then recompile and reinstall Xorg 6.9.0 from ports After enabling DRI and HWCursor, accelerated Xorg works. glxgears gives 1150 fps and video/dvd etc plays very smoothly with xvide= o = acceleration and xorg.conf VideoRam parameter set to 65536 (the default)= . It therefore appears this error was caused by a bug in the PCI bus = scanning in Xorg 6.9.0 rather than the AGP attach code. I could have downgraded the port to xorg-server 6.8.2 but shied away fro= m = recompiling loads of dependencies. I hope this is useful to someone and the fix makes it into the new drive= r = in modular Xorg.
