Subject: [PATCH v9 0/9] GICv3 LPI and ITS feature implementation
Date: Fri, 10 Sep 2021 10:39:42 -0400 [thread overview]
Message-ID: <20210910143951.92242-1-shashi.mallela@linaro.org> (raw)
This patchset implements qemu device model for enabling physical
LPI support and ITS functionality in GIC as per GICv3 specification.
Both flat table and 2 level tables are implemented.The ITS commands
for adding/deleting ITS table entries,trigerring LPI interrupts are
implemented.Translated LPI interrupt ids are processed by redistributor
to determine priority and set pending state appropriately before
forwarding the same to cpu interface.
The ITS feature support has been added to virt platform,wherein the
emulated functionality co-exists with kvm kernel functionality.
Changes in v9:
- removed sbsa-ref patch due to inconclusive ongoing discussion
regarding ITS placement and version in sbsa-ref platform.This will be
taken up as a separate functionality later
- updated its enable code as per latest virt 6.2
- updated its code to replace usage of MEMTX_ with bool
- All kvm_unit_tests PASS
- Verified Linux Boot functionality
