Arm generic timer provides different timers for different exception levels and different secure states. Because Armv8-R AArch64 has secure state only, the valid timer for hypervisor in EL2 is secure hypervisor physical timer. But for platform fvp-baser-aemv8r64, before FVP 11.18, the secure hypervisor physical timer could not work well in EL2, so we had been using Non-secure physical timer in EL2 for hypervisor as a workaround. Since secure hypervisor physical timer issue has been fixed from FVP 11.18, we can use this correct timer in EL2 for hypervisor now. So we update the device tree timer node to use secure hypervisor physical timer interrupt for hypervisor.

Introduction
This repository contains the Arm layers for OpenEmbedded.
-
meta-arm
This layer contains general recipes for the Arm architecture, such as firmware, FVPs, and Arm-specific integration.
-
meta-arm-autonomy
This layer is the distribution for a reference stack for autonomous systems.
-
meta-arm-bsp
This layer contains machines for Arm reference platforms, for example FVP Base, N1SDP, and Juno.
-
meta-arm-toolchain
This layer contains recipes for Arm's binary toolchains (GCC and Clang for -A and -M), and a recipe to build Arm's GCC.
-
meta-atp
This layer contains recipes for the Adaptive Traffic Generation integration into meta-gem5.
-
meta-gem5
This layer contains recipes and machines for gem5, a system-level and processor simulator.
Other Directories
-
ci
This directory contains gitlab continuous integration configuration files (KAS yaml files) as well as scripts needed for this
-
kas
This directory contains KAS yaml files to describe builds for systems not used in CI
-
scripts
This directory contains scripts used in running the CI tests
Contributing
Currently, we only accept patches from the meta-arm mailing list. For general information on how to submit a patch, please read https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
E-mail meta-arm@lists.yoctoproject.org with patches created using this process. You can configure git-send-email to automatically use this address for the meta-arm repository with the following git command:
$ git config --local --add sendemail.to meta-arm@lists.yoctoproject.org
Commits and patches added should follow the OpenEmbedded patch guidelines:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
The component being changed in the shortlog should be prefixed with the layer name (without the meta- prefix), for example:
arm-bsp/trusted-firmware-a: decrease frobbing level
arm-toolchain/gcc: enable foobar v2
Reporting bugs
E-mail meta-arm@lists.yoctoproject.org with the error encountered and the steps to reproduce the issue.
