[PATCH v1 0/8] GICv3 LPI and ITS feature implementation
Posted by Shashi Mallela 4 years, 10 months ago 
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.

  hw/intc: GICv3 ITS initial framework
  hw/intc: GICv3 ITS register definitions added

Running the kvm-unit-tests ITS set:

   env QEMU=$HOME/lsrc/qemu.git/builds/arm.all/qemu-system-aarch64 ./run_tests.sh -g its

with a patched unitests.cfg to remove the KVM requirement I get:

  PASS its-introspection (5 tests)
  FAIL its-trigger (6 tests, 1 unexpected failures)
  FAIL its-migration
  FAIL its-pending-migration (1 tests, 1 unexpected failures)
  SKIP its-migrate-unmapped-collection (1 tests, 1 skipped)

The its-migration asserts:

  Now migrate the VM, then press a key to continue...
  INFO: gicv3: its-migration: Migration complete

OK I've finished my first pass. I didn't want to keep repeating myself
with the later patches. So in summary:

  - use REG/FIELD to avoid the manual mask definition/manipulation
  - define registers in the patch that first uses them
  - check LOG_UNIMP vs LOG_GUEST_ERROR (and possibly assert if it
    shouldn't happen)
  - and of course pass the kvm-unit-tests ITS tests ;-) 

Thanks,
