from arto's messages to tech-x11:

The important change that was needed is that drm_scatter.c was
fixed to return pointer to all allocated pages, not just the
beginning of the allocated segments.

Other changes:

- drm_scatter maps COHERENT memory
- drm_drawable: drawable handle allocation is done
inside lock
- drm_memory: when mapping "agp" memory, store offset
of mapped area, so that new requests to same offset
return the same area instead of trying to remap
and fail
- drm_vm: use bus_space_mmap for frame buffer and registers

- r600_cp.c: ioremapfree allocated gart range
- radeon_cp.c: use mtsleep
- some memset calls I had added had their args swapped,
and no memory was cleared

merge the changes from drm 85b9f737db0d2a845e4d7e2bbf9ad12ff9e2227c
with our changes and the work recently done by Arto Huusko
<arto.huusko@pp2.inet.fi> and FUKAUMI Naoki <fun@naobsd.org>.

it includes all the changes arto provided from both mesa-drm and
the r6xx-r7xx-support branch. it does not yet include code to
handle the (deleted) drm_pciids.h file, but i'll probably just
check in a generated one for now.

i have not yet merged the changes from outside this dir.


from arto's messages to tech-x11:

The important change that was needed is that drm_scatter.c was
fixed to return pointer to all allocated pages, not just the
beginning of the allocated segments.

Other changes:

- drm_scatter maps COHERENT memory
- drm_drawable: drawable handle allocation is done
inside lock
- drm_memory: when mapping "agp" memory, store offset
of mapped area, so that new requests to same offset
return the same area instead of trying to remap
and fail
- drm_vm: use bus_space_mmap for frame buffer and registers

- r600_cp.c: ioremapfree allocated gart range
- radeon_cp.c: use mtsleep
- some memset calls I had added had their args swapped,
and no memory was cleared

When building r128drm(4), gcc objects to shifting into bit 31 of a
(signed) int. Make sure we are shifting an unsigned in those cases.

useful yet, but that's not a big deal since the latest xf86-video-ati
doesn't support DRM on these yet.

call the sysctl destroy functions upon failure and unload, which

from arto's messages to tech-x11:

The important change that was needed is that drm_scatter.c was
fixed to return pointer to all allocated pages, not just the
beginning of the allocated segments.

Other changes:

- drm_scatter maps COHERENT memory
- drm_drawable: drawable handle allocation is done
inside lock
- drm_memory: when mapping "agp" memory, store offset
of mapped area, so that new requests to same offset
return the same area instead of trying to remap
and fail
- drm_vm: use bus_space_mmap for frame buffer and registers

- r600_cp.c: ioremapfree allocated gart range
- radeon_cp.c: use mtsleep
- some memset calls I had added had their args swapped,
and no memory was cleared

implement DRM_RADEON_CS ioctl, necessary for r600_dri to function.

this is mostly from freebsd (though it also exists in other versions
of the drm code) svn commits:

SVN rev 196470 on 2009-08-23 14:55:57Z by rnoland

Add kernel support for Radeon R6/7xx 3D.

You will still need Mesa from git and possibly an updated DDX driver,
but this is working fairly well now.
