Subject: [PATCH 0/2] powerpc: kvm: generic framework and run posix timers in task context
Date: Mon, 21 Apr 2025 15:58:35 +0530	[thread overview]
Message-ID: <20250421102837.78515-1-sshegde@linux.ibm.com> (raw)

From: Gautam Menghani <gautam@linux.ibm.com>

This is an effort to use the generic kvm infra which handles check for 
need_resched, handling signals etc. i.e xfer_to_guest_mode_handle_work. 

kvm guests boots and runs stress-ng CPU stressor on PowerVM and on PowerNV. 
preempt=full and preempt=lazy was tested on PowerNV and in both cases the
KVM guest boots and runs stress-ng CPU stressor.

Please let me know if any specific testing to be done.  

Kept the patches separate since they differ functionally, but kept them
is a series since 2nd patch depends on functionality of 1st. Also this
could help in git bisect.  

This is based on tip/master
