Author: glebius Date: Mon Apr 17 17:34:47 2017 New Revision: 317061 URL: https://svnweb.freebsd.org/changeset/base/317061 Log: - Remove 'struct vmmeter' from 'struct pcpu', leaving only global vmmeter in place. To do per-cpu stats, convert all fields that previously were maintained in the vmmeters that sit in pcpus to counter(9). - Since some vmmeter stats may be touched at very early stages of boot, before we have set up UMA and we can do counter_u64_alloc(), provide an early counter mechanism: o Leave one spare uint64_t in struct pcpu, named pc_early_dummy_counter. o Point counter(9) fields of vmmeter to pcpu[0].pc_early_dummy_counter, so that at early stages of boot, before counters are allocated we already point to a counter that can be safely written to. o For sparc64 that required a whole dummy pcpu[MAXCPU] array. Further related changes: - Don't include vmmeter.h into pcpu.h. - vm.stats.vm.v_swappgsout and vm.stats.vm.v_swappgsin changed to 64-bit, to match kernel representation. - struct vmmeter hidden under _KERNEL, and only vmstat(1) is an exclusion. This is based on benno@'s 4-year old patch: https://lists.freebsd.org/pipermail/freebsd-arch/2013-July/014471.html Reviewed by: kib, gallatin, marius, lidl Differential Revision: https://reviews.freebsd.org/D10156 Modified: head/libexec/rpc.rstatd/rstat_proc.c head/sys/amd64/amd64/trap.c head/sys/amd64/include/atomic.h head/sys/amd64/include/counter.h head/sys/amd64/include/pcpu.h head/sys/arm/arm/intr.c head/sys/arm/arm/trap-v4.c head/sys/arm/arm/trap-v6.c head/sys/arm/arm/undefined.c head/sys/arm/include/counter.h head/sys/arm/include/pcpu.h head/sys/arm64/include/counter.h head/sys/arm64/include/pcpu.h head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_vnops.c head/sys/compat/linprocfs/linprocfs.c head/sys/fs/fuse/fuse_vnops.c head/sys/fs/nfsclient/nfs_clbio.c head/sys/fs/smbfs/smbfs_io.c head/sys/i386/i386/trap.c head/sys/i386/include/atomic.h head/sys/i386/include/counter.h head/sys/i386/include/pcpu.h head/sys/kern/kern_fork.c head/sys/kern/kern_intr.c head/sys/kern/kern_synch.c head/sys/kern/kern_thread.c head/sys/kern/subr_intr.c head/sys/kern/subr_syscall.c head/sys/kern/subr_trap.c head/sys/kern/vfs_bio.c head/sys/mips/include/counter.h head/sys/mips/include/intr_machdep.h head/sys/mips/include/pcpu.h head/sys/powerpc/include/counter.h head/sys/powerpc/include/pcpu.h head/sys/powerpc/powerpc/trap.c head/sys/sparc64/include/counter.h head/sys/sparc64/include/pcpu.h head/sys/sparc64/sparc64/exception.S head/sys/sparc64/sparc64/genassym.c head/sys/sparc64/sparc64/intr_machdep.c head/sys/sparc64/sparc64/machdep.c head/sys/sparc64/sparc64/trap.c head/sys/sys/pcpu.h head/sys/sys/vmmeter.h head/sys/vm/swap_pager.c head/sys/vm/vm_fault.c head/sys/vm/vm_meter.c head/sys/vm/vm_object.c head/sys/vm/vm_page.c head/sys/vm/vm_pageout.c head/sys/vm/vnode_pager.c head/sys/x86/acpica/srat.c head/sys/x86/x86/intr_machdep.c head/usr.bin/top/machine.c head/usr.bin/vmstat/vmstat.c Modified: head/libexec/rpc.rstatd/rstat_proc.c ============================================================================== --- head/libexec/rpc.rstatd/rstat_proc.c Mon Apr 17 17:23:19 2017 (r317060) +++ head/libexec/rpc.rstatd/rstat_proc.c Mon Apr 17 17:34:47 2017 (r317061) @@ -170,6 +170,7 @@ updatestat(void) struct timeval tm, btm;
