For some weeks now an RPi3 running -current has seemed rather slow....
On looking at the early part of the boot message the processor
attributes seem rather scant:
......
elease APs...APs not started
CPU 0: ARM Cortex-A53 r0p4 affinity: 0
Instruction Set Attributes 0 = <CRC32>
Instruction Set Attributes 1 = <>
Processor Features 0 = <AdvSIMD,FP,EL3 32,EL2 32,EL1 32,EL0 32>
Processor Features 1 = <>
Memory Model Features 0 = <TGran4,TGran64,SNSMem,BigEnd,16bit ASID,1TB PA>
Memory Model Features 1 = <8bit VMID>
Memory Model Features 2 = <32bit CCIDX,48bit VA>
Debug Features 0 = <2 CTX BKPTs,4 Watchpoints,6 Breakpoints,PMUv3,Debugv8>
Debug Features 1 = <>
Auxiliary Features 0 = <>
Auxiliary Features 1 = <>
CPU 1: (null) (null) r0p0 affinity: 0
CPU 2: (null) (null) r0p0 affinity: 0
CPU 3: (null) (null) r0p0 affinity: 0
............
In a top window, STATE is reported as RUN, rather than the
former CPUn.
Is a software switch now required to enable multiprocessing?
Or, could it be related to the lines:
psci0: PSCI version number mismatched with DT
as pointed out by Mark M in reference to the cpu_reset failed
problem, which is still manifest?
The kernel is at r357644.
Thanks for reading,
