Current merge queue

by Marcin Juszkiewicz

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). https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg01012.html Patch was discussed and then Peter Maydell proposed patch which handles that per CPU model. https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg04065.html 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

was trying qemu build with --enable-debug and hence the warnings were suppressed. Have resolved the warning now and updated the git repository.

GICv3 ITS code repo for review

by Shashi Mallela

Hi All, As discussed in the meeting today,please find my ITS code implementation from linaro git repo below ssh://git@git.linaro.org/people/shashi.mallela/qemu.git Please provide your review comments. While majority of the functionality is implemented,there are final changes to be done around GITS_TRANSLATER and referencing the ITS device into sbsa-ref which i shall update subsequently. Thanks Shashi

Insanely long time for each PE test in sbsa-acs

by Marcin Juszkiewicz

I run sbsa-acs in both QEMU and on HoneyComb to check how it goes. Recently I noticed long times of PE checks. For example "2 : Check for SIMD extensions" is running here for over 3 minutes. On machine with 4 emulated cpu cores (a72). That's with local git HEAD builds of QEMU, EDK2, Sbsa.efi using Fedora 10.2.1 cross compiler. Any ideas what is going on?
