Sorry Emil,

underneath this is omapdrm + PowerVR, so i should have prefixed it as:
"xf86-video-omap"...

Hi Robert,

My sleep deprived brain read omap, but registered freedreno. Or perhaps I'm a bit excited about the contributions from the CodeAurora/QCom guys in the latter case, which clouded my judgement :-)

Hey Robert,

I can update xf86-video-omap.. where there some other patches wanted/desired (has_dmm() iirc?)

Hi Rob,

The version i posted today has the "has_dmm" change merged in, which other then the README update is the only change I made.

static inline Bool has_dmm(OMAPPtr pOMAP)
{

src/omap_driver.h +1 -1

-       return pOMAP->chipset >= 0x4430;
+       return pOMAP->chipset >= 0x4430 || pOMAP->chipset == 0x0752;
 }

Haven't really heard back from TI about all the other random changes they made to their fork of your xf86-video-omap tree:

gotcha, well I've pushed your patch. I don't really have the hw unpacked and setup to test these days, but if someone confirm latest master is good then I suppose I should spin a release tag for distro's to pick up..

Thanks Rob!

I'll test and re-confirm on my x15 alpha board when i'm back in the lab on monday.
