Subject: [PATCH v6 0/6] Support for H_RPT_INVALIDATE in PowerPC KVM
Date: Thu, 11 Mar 2021 14:09:33 +0530 [thread overview]
Message-ID: <20210311083939.595568-1-bharata@linux.ibm.com> (raw)
This patchset adds support for the new hcall H_RPT_INVALIDATE
and replaces the nested tlb flush calls with this new hcall
if support for the same exists.
Changes in v6:
-------------
- Split the patch that adds hcall support in to three parts so that
it becomes easy to understand.
part1: hcall support for L1 guest
part2: hcall support for nested guests
part3: add KVM_CAP_PPC_RPT_INVALIDATE
- Renames, comments and code reorgs to improve readability of the
patches.
- Added a patch to fix comments in hcall args (Aneesh).
- Added hcall documentation as part of commit message.
- Correct handling for partition-scoped invalidation of nested
guests (Aneesh).
I haven't addressed the optimization that David suggested for
psize_to_rpti_pgsize() and that could be done later separately.
This patchset passes the following tests:
-----------------------------------------
- Boot and reboot of L1, L2 and L3 guests with GTSE=0.
- Boot and reboot of L1 and multiple L2 guests with GTSE=0
- vm class stress-ng tests on L3 with GTSE=0
- Boot and reboot of L1, L2 and L3 guest with GTSE=1
