Bugzilla Bug 148572

Following the changes to Mesa, new drm modules are required for DRI to work
properly.
I'm attaching what i've come up so far for x11-drm ebuild with g/fbsd support,
the only catch here is i'm not able to build dristat and drmstat. So far they
don't seem to be built either on vanilla freebsd.

Created an attachment (id=97690) [edit]
x11-drm-20060608-r1.ebuild

This is the whole ebuild, for easy looking at the big picture.

Created an attachment (id=97691) [edit]
x11-drm.diff

And this is the big patch to the current ebuild.

I'm not really happy with the organization of the code. I'll try to hack it
around some when I find a little time.

I'm glad that i'm not the only one.


And this is how dr{i,m}stat fails:

However, S_IFCHR is already defined in these places:

sys/stat.h:#define      S_IFCHR  0020000                /* character special */
xorg/xf86_libc.h:#define XF86_S_IFCHR 0020000
xorg/xf86_libc.h:#undef S_IFCHR
xorg/xf86_libc.h:#define S_IFCHR XF86_S_IFCHR

And sys/stat.h is already being included by 
../libdrm/xf86drm.c:58:# include <sys/stat.h>

Misses an include of sys/stat.h

The dristat/drmstat issue is solved by removing -D_POSIX_SOURCE from the CFLAGS
in tests/Makefile.

Little piece of the ebuild with the fix:
[...]
        elif use kernel_FreeBSD
        then
                cd "${S}/tests"
                # -D_POSIX_SOURCE skips the definition of several things we
need
                # for these two to compile
                sed -i -e "s/-D_POSIX_SOURCE//" Makefile
                make dristat || die "Building dristat failed."
                make drmstat || die "Building drmstat failed."
                mv dristat drmstat ${SRC_BUILD}
        fi
[...]

Still needs patches to get looked at.

I've comitted a less ugly ebuild to the transition overlay:
http://overlays.gentoo.org/proj/alt/browser/trunk/transition-overlay/x11-base/x11-drm/x11-drm-20060608-r1.ebuild
[sorry big url]

Sorry, I forgot about this. Keep bugging me.

In the hope this ebuild would resolve my DRI issues with mach64 driver, I've
installed the candidate ebuild but DRI still doesn't work.

My video card is:
ATI Technologies Inc 3D Rage Pro AGP 1X/2X (rev 5c)

$ glxinfo | grep rendering
direct rendering: No

May you open a new bug with all the relevant information please? With some more
information we can help a little more.

Tip: Make sure you're loading "/boot/modules" 'modules' instead of those in
"/boot/kernel".

Donnie: Any news on this ebuild before i forget as well ^_^?

No -- the problem is that I will need a somewhat large, single chunk of time to
do this, and that time has not existed yet. I've just had sporadic minutes to
work on Gentoo.

Donnie: spam ping, *poke in the eye*

I committed a masked revision, based on the overlay ebuild. Check it out.

Fixed, thanks for your work and patience.
