Subject: [PATCH v11 0/7] KVM: PPC: Driver to manage pages of secure guest
Date: Mon, 25 Nov 2019 08:36:24 +0530 [thread overview]
Message-ID: <20191125030631.7716-1-bharata@linux.ibm.com> (raw)
Hi,
This is the next version of the patchset that adds required support
in the KVM hypervisor to run secure guests on PEF-enabled POWER platforms.
This version includes the following changes:
- Ensure that any malicious calls to the 4 hcalls (init_start, init_done,
page_in and page_out) are handled safely by returning appropriate
errors (Paul Mackerras)
- init_start hcall should work for only radix guests.
- Fix the page-size-order argument in uv_page_inval (Ram Pai)
- Don't free up partition scoped page tables in HV when guest
becomes secure (Paul Mackerras)
- During guest reset, when we unpin VPA pages, make sure that no vcpu
is running and fail the SVM_OFF ioctl if any are running (Paul Mackerras)
- Dropped the patch that implemented init_abort hcall as it still has
unresolved questions.
