I now have my solaris agp driver to where it can be mmap-able from the user perspective. I have not tried to recompile xfree with it yet, because :
The "testgart" program I have, does an UNBIND and re-BIND as part of its testing. My driver fails the rebind. Is this rebinding common? The only time I can see this as being useful, is if the user-level program allocates more AGP keyed memory than the capacity of the aperture, and then uses UNBIND/reBIND as essentially fast-copy operations. However, if I'm reading the BSD agp driver, it does not allow AGPIOC_ALLOCATE of more memory than the size of the aperture. So what's the point? ----- ----- ---- ----- ----- ---- ----- ----- ---- Reason this is problematical: Solaris has a kernel entry point for mmap(). There is no munmap entry point. munmap is handled by the higher-level kernel routines 'automatically' So once a user maps a particular 'page' for the aperture... the appropriate page STAYS as that page for the aperture until the user calls munmap(). So willy-nilly bind/unbind/binding will not fly too well. _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
