the user when an invalid value is entered instead of silently falling back to the default 5s. While here I also capped the upper limit to UINT32_MAX / 1000000 to prevent useconds_t overflow. This hard limits us to 4294s, instead of the current soft limit which just make systat go berserk if you go over it.

2020-09-14pf: Merge NOTES column into NAME columnkn
NOTES stays unused unless pf.conf(5) contains "set loginterface ..." in which case it merely amends what can otherwise be part of the NAME column. Merge the constant NOTES values for conditional counters into their NAME values to make the "pf" view look a little nicer and less empty by default; this also saves screen estate for possible future changes, e.g. we could increase column widths.

Suspending systat with ^Z is done by the shell iff job control is enabled, not systat itself. Try "set +m" to disable job control or start systat in a terminal without a shell, e.g. "xterm -e systat", to confirm ^Z doing nothing in these cases. OK jmc

2020-05-15pf(4): use CLOCK_BOOTTIME to get time_uptime(9) in userspacecheloha
In pf(4), the pf_status.since timestamp is set with time_uptime(9). This is a low-res snapshot of nanouptime(9). nanouptime(9) is used to implement CLOCK_BOOTTIME for clock_gettime(2). It is not used to implement CLOCK_UPTIME, though. The names are misleading. Switch to CLOCK_BOOTTIME in places in userspace where we use pf_status.since so we are working with the right clock. Technically CLOCK_MONOTONIC is equivalent, but we shouldn't use that here. CLOCK_MONOTONIC is not necessarily the "time since boot": the standard says its absolute value is meaningless. ok patrick@ bluhm@

2018-11-17Add new KERN_CPUSTATS sysctl(2) so we can identify offline CPUs.cheloha
Because of hw.smt we need a way to determine whether a given CPU is "online" or "offline" from userspace. KERN_CPTIME2 is an array, and so cannot be cleanly extended for this purpose, so add a new sysctl(2) KERN_CPUSTATS with an extensible struct. At the moment it's just KERN_CPTIME2 with a flags member, but it can grow as needed. KERN_CPUSTATS appears to have been defined by BSDi long ago, but there are few (if any) packages in the wild still using the symbol so breakage in ports should be near zero. No other system inherited the symbol from BSDi, either. Then, use the new sysctl(2) in systat(1) and top(1): - systat(1) draws placeholder marks ('-') instead of percentages for offline CPUs in the cpu view. - systat(1) omits offline CPU ticks when drawing the "big bar" in the vmstat view. The upshot is that the bar isn't half idle when half your logical CPUs are disabled. - top(1) does not draw lines for offline CPUs; if CPUs toggle on or offline in interactive mode we redraw the display to expand/reduce space for the new/missing CPUs. This is consistent with what some top(1) implementations do on Linux. - top(1) omits offline CPUs from the totals when CPU totals are combined into a single line (the '-1' flag). Originally prompted by deraadt@. Discussed endlessly with deraadt@, ketennis@, and sthen@. Tested by jmc@ and jca@. Earlier versions also discussed with jca@. Earlier versions tested by jmc@, tb@, and many others. docs ok jmc@, kernel bits ok ketennis@, everything ok sthen@, "Is your stuff in yet?" deraadt@

2018-09-26KERN_CPTIME2: set ENODEV if the CPU is offline.cheloha
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@
