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 v7:
- Restructured the lpi pending table scan logic as per comments in v6
- Addressed minor comments from v6
- For sbsa-ref platform,ITS memory map has been inserted between
distributor & redistributors region similar to GIC-600 layout.
Also, introduced sbsa-ref versioning to reflect the latest its memory
map change and subsequent future use for helper functions
- All kvm_unit_tests PASS
- Verified Linux Boot functionality
