      "message": "powerpc: Implement accurate task and CPU time accounting\n\nThis implements accurate task and cpu time accounting for 64-bit\npowerpc kernels.  Instead of accounting a whole jiffy of time to a\ntask on a timer interrupt because that task happened to be running at\nthe time, we now account time in units of timebase ticks according to\nthe actual time spent by the task in user mode and kernel mode.  We\nalso count the time spent processing hardware and software interrupts\naccurately.  This is conditional on CONFIG_VIRT_CPU_ACCOUNTING.  If\nthat is not set, we do tick-based approximate accounting as before.\n\nTo get this accurate information, we read either the PURR (processor\nutilization of resources register) on POWER5 machines, or the timebase\non other machines on\n\n* each entry to the kernel from usermode\n* each exit to usermode\n* transitions between process context, hard irq context and soft irq\n  context in kernel mode\n* context switches.\n\nOn POWER5 systems with shared-processor logical partitioning we also\nread both the PURR and the timebase at each timer interrupt and\ncontext switch in order to determine how much time has been taken by\nthe hypervisor to run other partitions (\"steal\" time).  Unfortunately,\nsince we need values of the PURR on both threads at the same time to\naccurately calculate the steal time, and since we can only calculate\nsteal time on a per-core basis, the apportioning of the steal time\nbetween idle time (time which we ceded to the hypervisor in the idle\nloop) and actual stolen time is somewhat approximate at the moment.\n\nThis is all based quite heavily on what s390 does, and it uses the\ngeneric interfaces that were added by the s390 developers,\ni.e. account_system_time(), account_user_time(), etc.\n\nThis patch doesn\u0027t add any new interfaces between the kernel and\nuserspace, and doesn\u0027t change the units in which time is reported to\nuserspace by things such as /proc/stat, /proc/\u003cpid\u003e/stat, getrusage(),\ntimes(), etc.  Internally the various task and cpu times are stored in\ntimebase units, but they are converted to USER_HZ units (1/100th of a\nsecond) when reported to userspace.  Some precision is therefore lost\nbut there should not be any accumulating error, since the internal\naccumulation is at full precision.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"
