I've attached the patch that adds word- and byte-sized PCI configuration reads and writes for the ix86 platform. The particular reason was to fix the support of sincgle-chip Matrox G200 with the VESA driver on UnixWare. This hardware is somewhat brain-damaged and really expects word- and byte-sized bus cycles, it does not work with the wraping in Long. I fixed this in the int10 module before 4.6.0 RC2. It addressed the problems of this type that I saw. Try 4.6.0 RC3 and let me know if you still see the problem. Just a quick followup... I originally saw the problem when using the vesa driver with a G400. I have now verified 4.6.0 RC3 with the vesa driver and a G200. I don't have a working UnixWare system (I was never able to get it to play well in a multi-boot environment), but this is using XFree86's ix86 CFG1 PCI functions, not any of the OS-specific interfaces.

I guess I can import these changes from 6.9 - probably grab the whole directory, check that there are no other dependencies and drop it in. BTW, there also are changes in the x86emu code between Xorg 6.9 and XF86 4.5, the last release that I've downloaded a few weeks ago. They are somewhat diverging but I think there were more changes in Xorg 6.9 that weren't in XF86 4.5 than the other way around. Would you be interested in merging them in too? - checks for alignment; I'm not sure what to do about those. There is no way to return an error code, and no use for this error code in x86emu. Besides, for the ix86 platform the access is translated into the real Intel INB/INW instructions which are allowed to have non-aligned addresses, and if the BIOS had some reason to use a non-aligned address, I know no way to do anything better than to pass it through. -SB ___ Devel mailing list Devel@XFree86.Org http://XFree86.Org/mailman/listinfo/devel

Well, turns out that X.org list doesn't accept e-mail from non-subscribers. So be it, XF86 only then. :-) -SB ___ Devel mailing list Devel@XFree86.Org http://XFree86.Org/mailman/listinfo/devel
