Subject: [git pull] drm


Hi Linus,

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

This fixes some regressions and also a number of bugs in the Intel KMS and 
GEM code. Sorry its a bit bigger than I like sending, but I got backlogged 
with real life stuff and kept pushing this off.

I've got at least two more things to get fixed, Intel has a lockdep issue 
and I'm waiting for Eric to get back from travelling to confirm the fix is 
correct, and we have a radeon regression on susp/resume which I think is 
vblank related. This should fix your vblank issue and the CONFIG_FB fix 
from Ingo.

Dave.

commit d2f59357700487a8b944f4f7777d1e97cf5ea2ed

    drm/i915: select framebuffer support automatically
    
    Migration helper.
    
    The i915 driver recently added a 'depends on FB' rule to its
    Kconfig entry - which silently turns off DRM_I915 if someone
    has a working config but no CONFIG_FB selected, and upgrades
    to the latest upstream kernel.
    
    Norbert Preining reported this problem:
    
       Bug-Entry   : http://bugzilla.kernel.org/show_bug.cgi?id=12599
       Subject     : dri /dev node disappeared with 2.6.29-rc1
    
    So change it to "select FB", which auto-selects framebuffer
    support. This way the driver keeps working, regardless of
    whether FB was enabled before or not.
    
    Kconfig select's of interactive options can be problematic to
    dependencies and can cause build breakages - but in this case
    it's safe because it's a leaf entry with no dependencies of its
    own.
    
    ( There is some minor circular dependency fallout as FB_I810
      and FB_INTEL also used 'depends on FB' constructs - update
      those to "select FB" too. )

    drm/i915: add get_vblank_counter function for GM45
    
    As discussed in the long thread about vblank related timeouts, it turns out
    GM45 has different frame count registers than previous chips.  This patch
    adds support for them, which prevents us from waiting on really stale
    sequence values in drm_wait_vblank (which rather than returning immediately
    ends up timing out or getting interrupted).

    drm/i915: capture last_vblank count at IRQ uninstall time too
    
    In dc1336ff4fe08ae7cfe8301bfd7f0b2cfd31d20a (set vblank enable flag correctly
    across IRQ uninstall), we made sure drivers that uninstall their interrupt
    handler set the vblank enabled flag correctly, so that when interrupts are
    re-enabled, vblank interrupts & counts work as expected.  However I missed the
    last_vblank field:  it needs to be updated as well, otherwise, at the next
    drm_update_vblank_count we'll end up comparing a current count to a stale
    one (the last one captured by the disable function), which may trigger the
    wraparound handling, leading to a jumpy counter and hangs in drm_wait_vblank.
    
    The jumpy counter can prevent the DRM_WAIT_ON from returning success if the
    difference between the current count and the requested count is greater than
    2^23, leading to timeouts or hangs, if the ioctl is restarted in a loop (as
    is the case in libdrm < 2.4.4).

    drm/i915: Quiet the message on get/setparam ioctl with an unknown value.
    
    Getting an unknown get/setparam used to be more significant back when they
    didn't change much.  However, now that we're in the git world we're using
    them instead of a monotonic version number to signal feature availability,
    so clients ask about unknown params on older kernels more often.

    drm/i915: add fence register management to execbuf
    
    Adds code to set up fence registers at execbuf time on pre-965 chips as
    necessary.  Also fixes up a few bugs in the pre-965 tile register support
    (get_order != ffs).  The number of fences available to the kernel defaults
    to the hw limit minus 3 (for legacy X front/back/depth), but a new parameter
    allows userspace to override that as needed.
