and making it build by updating axpPci.c to the new interfaces doesn't seem to give a working server.  Ian, any chance you could take a look at this, since it's pciaccess-related?

Make xserver build on Alpha

As per our discussion on IRC, the attached patch makes the xserver build on Alpha.  In my testing with MGA, it runs until the driver tries to map its BARs.  It appears that /sys/bus/pci/devices/0000:00:0b.0/resource0 and friends are missing on Alpha Linux.  libpciaccess mmaps these files to give the driver access to the BARs.  Without these files, libpciaccess based X-servers are (currently) DOA.

We either need to get the resource# mappings supported by the kernel on Linux or add all the Alpha-specific cruft (from axpPci.c) and /dev/mem mapping support to libpciaccess.
Comment 3 Adam Jackson 2008-06-17 10:11:24 UTC 
Committed that patch to server 1.5 and master.

I'm of the opinion that the alpha port in the kernel needs to get with the program, so I'm closing this one as fixed.  If someone really wants to add axp stuff to libpciaccess, reopen, but otherwise, go fix the kernel.
