At that time it was decided to do platform versioning first. 1. https://lore.kernel.org/qemu-devel/20210812165341.40784-8-shashi.mallela@linaro.org/ Now we are going through our list of changes for SBSA Reference Platform and GIC ITS is one of early ones. There was decision that there will be no option to disable it and platform version will get a minor bump. This is refreshed version of v8 one from 2021. GIC ITS is placed behind GIC Redistributor in memory space to allow use of older EDK2 firmware. New address is placed in DeviceTree for firmware to use. Due to it we also bump platform version to 0.2 version. Trusted Firmware will read GIC ITS address and provide to EDK2 via Secure Monitor Call (SMC). Same way as it is done with GIC addresses already. Changes since v1: - everything in one patch - removed bogus check for kvm_irqchip_in_kernel() - documentation about platform version changes added Shashi Mallela (1): hw/arm/sbsa-ref: add ITS support in SBSA GIC docs/system/arm/sbsa.rst | 14 ++++++++++++++ hw/arm/sbsa-ref.c | 33 ++++++++++++++++++++++++++++++--- 2 files changed, 44 insertions(+), 3 deletions(-)
