I don't think this is the place to add codecs that should go into mainstream linux |
|
The pull request includes RPi drivers as well... |
|
the DAC has only 2 channels, not 8. |
|
You are right, I forgot to put my name on the modules. Going to edit them. Thanks |
|
It is the right place - as WallaceIT said, it includes all the bindings for the Raspberry Pi. The driver alone might be useable for mainstream linux, but since it includes only a few definitions, I would postpone this until the I2S driver itself is upstream. I am looking forward to your corrected version. |

This bug is introduced by commit 9f00b2e (bridge: only expire the mdb entry when query is received). Same for __br_mdb_del().

When booting secondary CPUs, announce_cpu() is called to show which cpu has been brought up. For example: [ 0.402751] smpboot: Booting Node 0, Processors #1 #2 #3 #4 #5 OK [ 0.525667] smpboot: Booting Node 1, Processors #6 #7 #8 #9 #10 #11 OK [ 0.755592] smpboot: Booting Node 0, Processors #12 #13 #14 #15 #16 #17 OK [ 0.890495] smpboot: Booting Node 1, Processors #18 #19 #20 #21 #22 #23 But the last "OK" is lost, because 'nr_cpu_ids-1' represents the maximum possible cpu id. It should use the maximum present cpu id in case not all CPUs booted up.
