You said you are enabling VDPU121, the JPEG decoder. But we don't have a JPEG decoder driver mainline, is there some patches missing ? Nicolas > > reg: > maxItems: 1 > -- > 2.34.1 >

This is about getting H264, VP8 and MPEG2 out of these extra cores of course. I still would like to know how we will express the grouping of these four cores, so a driver can know they are identical G1 cores and not bound to be time sliced with an H1 core like the fifth one? I want to see a plan that will work and will not cause headache for future work on fully utilizing the HW resources. Nicolas
