Hi Tony, I found some time to update my drivers/stating/pvr/1.14.369993 tree to make use of the new sgx soc integration code and it works on omap5! > root@letux:~# modprobe pvrsrvkm_omap_omap5_sgx544_116 > [ 106.478254] pvrsrvkm_omap_omap5_sgx544_116: module is from the staging directory, the quality is unknown, you have been warned. > [ 106.526201] [drm] Initialized pvr 1.14.3699939 20110701 for 5600fe00.sgx on minor 1 > root@letux:~# pvrsrvctl --no-module --start > [ 261.091978] PVR_K: UM DDK-(3699939) and KM DDK-(3699939) match.

Or I am missing some of your PRM rstctrl patches since I am working on top of linus/master. Because of that I had to comment out prm_gfx in am33xx.dtsi to get it compile and could not test yet on Beagle Bone. A little unclear is how to properly handle omap4. omap4430/4440 and 4460 have the sgx540 while only omap4470 has an sgx544 inside. But omap4420/30 share one .dtsi and omap4460/70 the other. So we might have to define a new omap4470.dtsi and #include in the real omap4470 boards. And am3517 and am43/am57/am65/... support is missing. But that can be added later if we have it running on omap3 and am33xx. Anyways, we again have made a big step forwards. Let's hope that we can get the FLOSS part of the sgx drivers to staging in some not too far future.
