List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 08 Feb 2020 01:19:35 -0000 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 = Instruction Set Attributes 1 = <> Processor Features 0 = Processor Features 1 = <> Memory Model Features 0 = 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, bob prohaska
