[edk2-devel] [PATCH edk2-platforms 0/1] Platform/QemuSbsa: define NS EL2 virtual timer in GTDT

Posted by Marcin Juszkiewicz 7 months, 2 weeks ago

Arm BSA (Base System Architecture) specification requires Armv8.1+ cpus
to have non-secure EL2 virtual timer. Which we lacked.

In previous week I wrote a small patch to QEMU which enabled it for SBSA
Reference Platform. Leif Lindholm refactored code around timers to make
it more readable.

Then he added missing timer into EDK2 ArmPkg and to "virt" platform.

This patch enables NS EL2 virtual timer on SBSA Reference Platform.
