Subject: [PATCH v2 0/8] GICv3 LPI and ITS feature implementation
Date: Wed, 31 Mar 2021 22:41:44 -0400 [thread overview]
Message-ID: <20210401024152.203896-1-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 v2:
- used FIELD to avoid manual mask definition/manipulation
- defined registers in patches that first use them
- changed LOG_GUEST_ERROR to LOG_UNIMP for unimplemented code
- all kvm-unit-tests passed except 1 inapplicable case of its-trigger
which assumes presence of redistributor caching
