riscv: kvm: use generic entry for TIF_NOTIFY_RESUME and misc

[PATCH v3 0/3] riscv: kvm: use generic entry for TIF_NOTIFY_RESUME and misc

Posted by Jisheng Zhang 3 years, 6 months ago

This series is a preparation series to add PREEMPT_RT support to riscv:
patch1 adds the missing number of signal exits in vCPU stat
patch2 switches to the generic guest entry infrastructure
patch3 select HAVE_POSIX_CPU_TIMERS_TASK_WORK which is a requirement for
RT

After these three patches merged, the left RT patches are similar as
other arch.

Since v2:
  - splict the series into two separate ones, one for next another for
    RT.

Since v1:
  - send to related maillist, I press ENTER too quickly when sending v1
  - remove the signal_pending() handling because that's covered by
    generic guest entry infrastructure

Jisheng Zhang (3):
  RISC-V: KVM: Record number of signal exits as a vCPU stat
  RISC-V: KVM: Use generic guest entry infrastructure
  riscv: select HAVE_POSIX_CPU_TIMERS_TASK_WORK

I have queued this series for Linux-6.1

Thanks,
