Alex's assertion no longer holds now that all the major Itanium chipsets are properly supported. Besides, ATIAvoidCPIO (and ATIAvoidNonPCI) are merely stopgaps which I intend to deprecate.

getpagesize() as invoked from a driver is aliased to xf86getpagesize(),
which does this:

...

xf86getpagesize()
{
static int pagesize = -1;
if (pagesize != -1)
return pagesize;
#if defined(_SC_PAGESIZE) || defined(HAS_SC_PAGESIZE)
pagesize = sysconf(_SC_PAGESIZE);

As I said when I reviewed this originally, getpagesize(), which is aliased to xf86getpagesize(), should reliably find the page size on all architectures, so this comment is redundant. DRM_PAGE_SIZE should simply be defined to getpagesize(), providing that is consistent with what the kernel interfaces expect.

Are you saying that the line with r128_drm_page_size should be the following: r128_drm_page_size = sysconf(_SC_PAGESIZE) If so, I will change it, but I cannot test it as I don't have access to ia64 hardware.

If you had, I'd have told you that that patch is an ugly mess, not suitable for upstream submission for numerous reasons. It works, but it is far from clean and ready for inclusion in CVS. Before submitting my patches upstream, please contact me first to find out what my own plans are. I generally send patches upstream myself personally when I feel they are ready to be included upstream. If I haven't, it is a good idea to ask me why not first.

No, please don't. Those pagesize patches are ugly hacks currently, and are not suitable for XFree86.org. Don't waste their time please. -- Mike A.

I can't remember the specific, but HPUX had an issue with one I recall. I'd have to hunt down the manual I found that indicated this however. This should be dealt with in a very nice way by xf86getpagesize() more or less. There are some fixes that need to happen, at least from 4.3.0 codebase (not sure about current CVS head), but they need to be done in a clean manner. I intend to go through everywhere in the server and clean up anything I find at some point, and then send a proper patch in to fix it all, unless someone beats me to it.
