| 2017-03-03 | sched/headers: Move cputime functionality from <linux/sched.h> and ↵ | Ingo Molnar | 1 | -13/+0 | |
| <linux/cputime.h> into <linux/sched/cputime.h> Move cputime related functionality out of <linux/sched.h>, as most code that includes <linux/sched.h> does not use that functionality. Move data types that are not included in task_struct directly to the signal definitions, into <linux/sched/signal.h>. Also merge the (small) existing <linux/cputime.h> header into <linux/sched/cputime.h>.

| 2017-02-01 | sched/cputime: Remove generic asm headers | Frederic Weisbecker | 1 | -0/+2 | |
| cputime_t is now only used by two architectures: * powerpc (when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y) * s390 And since the core doesn't use it anymore, we don't need any arch support from the others. So we can remove their stub implementations. A final cleanup would be to provide an efficient pure arch implementation of cputime_to_nsec() for s390 and powerpc and finally remove include/linux/cputime.h .

| 2014-03-13 | cputime: Bring cputime -> nsecs conversion | Frederic Weisbecker | 1 | -0/+5 | |
| We already have nsecs_to_cputime(). Now we need to be able to convert the other way around in order to fix a bug on steal time accounting.

| 2014-03-13 | cputime: Default implementation of nsecs -> cputime conversion | Frederic Weisbecker | 1 | -0/+11 | |
| The architectures that override cputime_t (s390, ppc) don't provide any version of nsecs_to_cputime(). Indeed this cputime_t implementation by backend only happens when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y under which the core code doesn't make any use of nsecs_to_cputime(). At least for now. We are going to make a broader use of it so lets provide a default version with a per usecs granularity. It should be good enough for most usecases.
