[PATCH v1 0/8] GICv3 LPI and ITS feature implementation


From: Shashi Mallela
Subject: [PATCH v1 0/8] GICv3 LPI and ITS feature implementation
Date: Tue, 23 Mar 2021 00:12:30 -0400

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.

Shashi Mallela (8):
  hw/intc: GICv3 ITS initial framework
  hw/intc: GICv3 ITS register definitions added
  hw/intc: GICv3 ITS command queue framework
  hw/intc: GICv3 ITS Command processing
  hw/intc: GICv3 ITS Feature enablement
  hw/intc: GICv3 redistributor ITS processing
  hw/arm/sbsa-ref: add ITS support in SBSA GIC
  hw/arm/virt: add ITS support in virt GIC
