Hi, long time no mail so let me tell you how our merge queue looks:

1. Leif wrote patchset for TF-A to add 'max' cpu support.

This gives us CPU with all/most features supported in QEMU. Compared to 'cortex-a72' we use now we get some tests pass for level 4 and above.

https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/9112

Code to enable 'max' cpu model for sbsa-ref is already merged into QEMU tree.

Passed tests:

20 : Check for 16-Bit VMID : Result: PASS 21 : Check for Virtual host extensions : Result: PASS 22 : Check for pointer signing : Result: PASS 27 : Check for SHA3 and SHA512 support : Result: PASS 31 : Check PEs Implement SB Barrier : Result: PASS 32 : Check PE Impl CFP,DVP,CPP RCTX : Result: PASS 33 : Check Branch Target Support : Result: PASS

2. I sent patch to QEMU to bump amount of PMU counters to six (required by both BSA and SBSA).

Patch was discussed and then Peter Maydell proposed patch which handles that per CPU model.

Passed tests:

12 : Check number of PMU counters : Result: PASS

3. GIT ITS enablement done by Shashi.

This work has two parts: QEMU and EDK2.

https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg05315.html

https://edk2.groups.io/g/devel/message/72682?p=,,,20,0,0,0::Created,,shashi,...

This allows us to pass ITS related tests and allows us to add SMMU handling.

Passed tests:

102 : If PCIe, then GIC implements ITS : Result: PASS
