From c2c8844316a12c2e1a3314e4f021815dd7fc7b47 Mon Sep 17 00:00:00 2001 From: Shrikanth Hegde Date: Thu, 9 Jul 2026 14:51:41 +0530 Subject: [PATCH] powerpc: enable to run posix cpu timers in task context Now that all kvm entry to guest paths handle the task work using the generic framework, enable HAVE_POSIX_CPU_TIMERS_TASK_WORK which allows running posix cpu timers in task context instead of running them in hardirq. This would is a necessary step towards enabling PREEMPT_RT on powerNV systems.
