| stekern | shorne: I don't quite understand the master slave logic, is cpu0 always the master (e.g. boot cpu is master the other slaves)? | 01:32 |
|---|---|---|
| stekern | if so, should the master sync really be in _cpu_up()? | 01:36 |
| stekern | afaict, that's being called for every cpu that is being brought up | 01:36 |
| shorne | stekern: well cpu up is called buy cpu[0] to kick cpu[n] | 04:52 |
| shorne | (as I understand it) | 04:52 |
| shorne | so, after boot_secondary() is called, the master (cpu[0]) calls sync_count_master(cpu). | 04:53 |
| shorne | To wait for the secondary cpu (cpu[n]) to call syn_count_clast(cpu) with same value for `cpu`. Then they will sync clocks | 04:54 |
| shorne | then master (cpu[0]) will return form sync_count_master(), and continue booting other cpus | 04:55 |
| shorne | and secondary cpu/slave (cpu[n]) will finish its startup and go to idle task | 04:56 |
| stekern | ok, that may be the case | 05:44 |
