Subject: [PATCH v8 00/10] GICv3 LPI and ITS feature implementation
Date: Thu, 12 Aug 2021 12:53:31 -0400 [thread overview]
Message-ID: <20210812165341.40784-1-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 sbsa-ref platform as well as
virt platform,wherein the emulated functionality co-exists with kvm
kernel functionality.
Changes in v8:
- moved tcg ITS support to virt platform 6.1 options (since it will be
supported in 6.2)
- modified the ite entry access offset based on latest test results
- All kvm_unit_tests PASS
- Verified Linux Boot functionality
