Hello Emmanuel, >> Can I ask for help to identify which clock shown in 11.2 boot log are >> missing in 12.4 boot log? >> > It seems that we are missing some clocks. > We don't support the audio pll and so don't support the codec gate > which is the one that the driver is expecting to find. It is very bad news for me. So it looks that sound cards can't work on any A10/A20 chip with post FreeBSD 11 even sound driver is part of the tree.

I expect you mention that sys/arm/allwinner/clk/aw_pll.c was not ported to FreeBSD 12 clkng (sys/arm/allwinner/clkng/). If you mention "do not support" mean really just code migration/testing or it can't be supported because of any new kernel feature/architecture? In other words if I will focus on migration, could it work? Best regards, Jirka Novak -- Ing. Jiří Novák | CTO, Systems Engineer NET-SYSTEM s.r.o.
