Re: [XFree86] Sol/Sparc: XLUT MapSbusMem failure

The Solaris 8 man page for mmap(2) mentions: The mmap() function will fail if: EACCES The fildes file descriptor is not open for read, regardless of the protection specified, or fildes is not open for write and PROT_WRITE was specified for a MAP_SHARED type mapping. Well, the same file descriptor is being used for all three regions and it is definitely being open()'ed for read write, so I don't see why the XLUT mmap() is the only one failing with EACCES. However, it seems the OS' device driver is imposing additional restrictions not documented in the mmap() man page, given FB and X32 private mmap()'s are being nixed. What do(es) the cg14 related man page(s) say?

I am running as root for now, perhaps I don't have enough memory? I have 4MB of video memory, if the X server will only run in 32bpp mode it might not be enough. I'll keep updating from CVS and checking out new builds (this test was done with 4.3.99.6). Thanks!!! On Thu, 2003-06-12 at 10:50, Marc Aurele La France wrote: OK.

Thanks for reporting the problem. Unfortunately this patch produces the same effect. (After patching, I removed Sbus.o and re-ran make Everything.) xf86MapSbuMem still fails to map the XLUT region of memory. But thank you boatloads for trying. if you would like to me to try anything else, let me know (it's not important and I will be trying to next release). OK.
