 	Hi

   Now that KMS for radeon is turned on, you should actively monitor 
upstream for fixes to the drm layer. Here is a post which lists some which 
are now in .33 and F12. I'm sure that .33 has more, but I don't have a 
list of those, nor do I have hw to test them.

Subject: [git pull] drm fixes


Hi Linus,

Please pull the 'drm-linus' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-linus

I've pulled the most required patches from the optional pull that you
didn't take from last week. Granted this means the F12 kernel has now got
a bunch of patches that should be in 2.6.32 but will have to wait for
2.6.33, distros thinking of packaging radeon kms do take note.

Dave.

     drm/fb: fix FBIOGET/PUT_VSCREENINFO pixel clock handling

     When the framebuffer driver does not publish detailed timing information
     for the current video mode, the correct value for the pixclock field is
     zero, not -1.

     Since pixclock is actually unsigned, the value -1 would be interpreted
     as 4294967295 picoseconds (i.e., about 4 milliseconds) by
     register_framebuffer() and userspace programs.

     This patch allows X.org's fbdev driver to work.

     drm: make sure page protections are updated after changing vm_flags

     Some architectures compute ->vm_page_prot depending on ->vm_flags, so we
     need to update the protections after adjusting the flags.

     AFAIK this only affects running X under Xen; without this patch you get
     lots of coloured blobs on the screen, or maybe a complete lockup.  Or
     anything really.

     But that still depends on lots of out-of-tree stuff, so I don't think
     there are any consequences for anyone else.  But it is wrong in principle.

     drm/radeon/kms: Report vga connector is connected according to ddc_probe

     On broken EDID we were reporting vga connector to be disconnected
     even if ddc probe did found a monitor. This patch report that the
     connector is connected on such case. This allow drm to add a fail
     safe mode (800x600 at the time of this patch) thus user can boot
     and later add a mode which match its monitor capabilities.

     drm: mm always protect change to unused_nodes with unused_lock spinlock

     unused_nodes modification needs to be protected by unused_lock spinlock.
     Here is an example of an usage where there is no such protection without
     this patch.

       Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list)
                  2-spin_lock(spinlock protecting mm struct)
                  3-drm_mm_put_block(this function might modify unused_nodes
                    list but doesn't protect modification with unused_lock)
                  4-spin_unlock(spinlock protecting mm struct)
       Process2:  1-drm_mm_pre_get(this function modify unused_nodes list)
     At this point Process1 & Process2 might both be doing modification to
     unused_nodes list. This patch add unused_lock protection into
     drm_mm_put_block to avoid such issue.

     drm/radeon/kms: Disable TV load detect on RS400,RC410,RS480

     RS400,RC410,RS480 chipset seems to report a lot of false positive
     with load detect on TV output. We haven't yet found a way to make
     load detect reliable on those chipset, thus just disable it for TV
     output. Would avoid user to experience phantom screen because X
     believe there is a monitor connected to the TV output.

     drm/radeon/kms: read back register before writing in IIO.

     This fixes RH bugzilla #527874.

     On resume the atom posting wasn't working, however vbe posting was
     going fine, after 2 weeks over irc, and 8 hrs with the hardware,
     I tracked it down to the memory device table and it access the MC
     registers via IIO, it appears the rv515 atom iio table might not
     be fully functional, so adding a readback before doing a write
     either provides enough delay to make things resume correctly.

     Thanks to Peng Huang at Red Hat for coming to Brisbane.

     drm/radeon/kms: resume AGP by calling init.

     AGP resume was broken since we moved to the new init path,
     because we never re-enabled AGP on these systems at resume time.

     This patch just calls the AGP resume call which just does the reinit
     at resume time like the old path did.

     Since AGP is pretty much gpu independant I did it outside
     the gpu specific code.
