The cover letter from Nicolas includes: > [ 501.321752] panfrost 13040000.gpu: shader_present=0x7 l2_present=0x1 0x7 is three bits set, so it certainly looks like there are 3 shader cores. Of course I wouldn't guarantee that it is as simple as each power domain has a shader core in. The job manager and tiler also need to be powered somehow, so they are either sharing with a shader core or there's something more complex going on. Steve
