[Freedreno] kernel and prebuilts update

[Rob Clark]

Hey, just to let everyone know, there are updated prebuilt kernels
(matching the kernel branches which have been rebased against latest
msm-next for 3.14).

http://people.freedesktop.org/~robclark/f20/20140207/



Userspace Status:
-----------------
Userspace has latest mesa (including new-compiler, hw binning, etc).. see:
http://bloggingthemonkey.blogspot.com/2014/02/freedreno-new-compiler.html

Also included is rebased mesa part of XA.  But not yet the
xf86-video-freedreno part, which is still work in progress.  The
original XA work pre-dated drm/msm and kms, so had some issues around
pageflips (fixed now), and resolution changes (still debugging).

Once there is something usable I'll make a prebuilt tgz with XA
enabled, as it is a significant improvement for windowed apps (~2x)..
hitting 860fps/1200fps (a320/a330) for es2gears.  And glmark2 results
for a320 are not looking too bad either, see results at end.



Kernels:
--------
I updated all the kernels this morning to pull in some fixes, so if
you rebased against any of these branches earlier in the week, you
might want to rebase again. There is a fixed a backport issue ("drm
backport from v3.14-rc1 (v2)") and few other fixes, in particular for
some bugs that XA was triggering.

bstem-drm:

  resynced with latest upstream, pulled in hdmi audio, wifi driver,
  and various display underflow (blue flash) fixes that were previously
  missing on this branch.

  note that the kernel parts needed for audio are there, but we still
  need alsa UCM config files for this device.

ifc6410-drm:
ifc6410-drm-overclock:

  resynced with latest upstream, plus pulled in wifi driver

dragonboard-drm:

  resynced with latest upstream, various fixes

WIFI NOTE: if you are using multiple devices on a single wireless
network, you probably need to edit the softmac.bin in the initrd to
avoid them all having the same MAC addr.  If you build your own
kernel, and build wifi (CONFIG_ATH_COMMON, CONFIG_ATH6KL and
CONFIG_ATH6KL_SDIO) as modules, then softmac does not need to be in
initrd.



Results with XA:
----------------

On bstem board with a320.. results on inforce board with stock clocks
should be same, or a bit higher if overclocked.  And a bit higher
still on apq8x74/a330.
