Increase the timeout from previous commit further. Rather than warning we have spun out (to which there are consequences), we should spin longer. The BSP really wants the APs to finish. |

KERN_CPTIME2: set ENODEV if the CPU is offline. This lets userspace distinguish between idle CPUs and those that are not schedulable because hw.smt=0. A subsequent commit probably needs to add documentation for this to sysctl.2 (and perhaps elsewhere) after the dust settles. Also included here are changes to systat(1) and top(1) that account for the ENODEV case and adjust behavior accordingly: - systat(1)'s cpu view prints placeholder marks ('-') instead of percentages for each state if the given CPU is offline. - systat(1)'s vmstat view checks for offline CPUs when computing the machine state total and excludes them, so the CPU usage graph only represents the states for online CPUs. - top(1) does not draw CPU rows for offline CPUs when the view is redrawn. If CPUs "go offline", percentages for each state are replaced by placeholder marks ('-'); the view will need to be redrawn to remove these rows. If CPUs "go online" the view will need to be redrawn to show these new CPUs. In "combined CPU" mode, the count and the state totals only represent online CPUs. Ports using KERN_CPTIME2 will need to be updated. The changes described above to make systat(1) and top(1) aware of the ENODEV case *and* gracefully handle a changing HW_NCPUONLINE while the application is running are not necessarily appropriate for each and every port. The changes described above are so extensive in part to demonstrate one way a program *might* be made robust to changing CPU availability. In particular, changing hw.smt after boot is an extremely rare event, and this needs to be weighed when updating ports. The logic needed to account for the KERN_CPTIME2 ENODEV case is very roughly: if (sysctl(...) == -1) { if (errno != ENODEV) { /* Actual error occurred. */ } else { /* CPU is offline. */ } } else { /* CPU is online and CPU states were set by sysctl(2). */ } Prompted by deraadt@. Basic idea for ENODEV from kettenis@. Discussed at length with kettenis@. Additional testing by tb@. No complaints from hackers@ after a week. ok kettenis@, "I think you should commit [now]" deraadt@ |
