scott, as of today, there is no DDK1.8 that works with X11. hence we
cannot move Ubuntu to 1.8. we are tracking this internally, but it
requires engineering effort to make the transition, and there is no good
reason and no resources to do it now (except to align ubuntu and android
DDK which is not a must have as of today for us).

also the DDK1.7 was especially made to allow a reuse of the kernel
driver between Android and Ubuntu (Motorola BIONIC is the reason why
this happens...), there is no reason to believe that the DDK1.8 will
offer that too...

However, the linaro kernel includes the PVR driver for GB indeed
(DDK1.7) but for Ubuntu we use an external PVR module that is provided
as an out-of-driver. so you might be able to update the in-tree PVR to
1.8 without impacting Ubuntu images at all.

that said, I believe that GFX in ICS will require much more drivers than
just PVR. there are new dss features in the ICS OMAP kernel, as well as
new components such as dsscomp or ion which is required for GFX in ICS.

I would definitely recommend that we main a common base kernel used for
Ubuntu and put the Android stuff in another branch as I am not sure if
the android bits will impact Ubuntu GFX... it might be able to be
managed with flags eventually, but let's start with a branch.

Title:
  SGX driver failing on ICS on tracking-panda

Status in Linaro Android:
  New
Status in Linaro Texas Instruments Landing Team:
  New

Bug description:
  SGX driver is failing on tracking-panda build https://android-build.linaro.org/builds/~linaro-android/tracking-panda/   .  The build is excluding the binaries from http://git.omapzoom.org/?p=device/ti/proprietary-open.git  . After adding the binaries manually, ICS fails to boot with the error
  PVR_K:(Error): BridgedDispatchKM: Driver initialisation not completed yet. [4652, drivers/gpu/pvr/bridged_pvr_bridge.c]
  [   21.756896] PVR_K:(Error): BridgedDispatchKM: Driver initialisation not completed yet. [4652, drivers/gpu/pvr/bridged_pvr_bridge.c] .

  
  the SGX driver and binaries need to be updated for ICS.
