QemuQ35Pkg: Increase QEMU extended TSEG to 32 MB @Flickdm (#1345)

Change Details

Description

Add the -global mch.extended-tseg-mbytes=32 argument to the QEMU runner to increase the extended TSEG from the QEMU default of 16 MB to 32 MB. Update the PcdQ35TsegMbytes PCD comment to note the QEMU default extended TSEG size of 16 MB.

How This Was Tested

During OneCrypto testing it was seen that with OneCrypto + existing conditions - this pushed TSEG usage to 16.3 MB causing TSEG memory exhaustion. Increasing the TSEG to 32Mb allows for the platform to boot.

I will also investigate why we're pushing TSEG usage to 16.3 to determine if this is normal / expected or if there is something we should / can do to reduce the pressure.

UPDATE:

It appears that Openssl 3 performs a lot of small allocations during its initialization and when combined with Pool guard - this exhausts a 16Mb TSEG.

Specifically this line enables pool guard : https://github.com/microsoft/mu_tiano_platforms/blob/54f18bd28fe16b41e51785af1aa9b51627f244a7/Platforms/QemuQ35Pkg/PlatformPei/Platform.c#L800

With this disabled, the platform will be able to boot normally with 16Mb TSEG.

Leaving it enabled for QemuQ35 is recommended - as it's useful for detecting memory bugs early before they reach physical platforms. Meaning that increasing the TSEG here is acceptable.

This was tested in both DEBUG and RELEASE using the following commands (after building):

DEBUG

python Platforms/QemuQ35Pkg/PlatformBuild.py TOOL_CHAIN_TAG=GCC5 PATH_TO_OS=ValidationOS.qcow2 QEMU_ACCEL=kvm --FlashOnly

RELEASE

python Platforms/QemuQ35Pkg/PlatformBuild.py TOOL_CHAIN_TAG=GCC5 PATH_TO_OS=ValidationOS.qcow2 QEMU_ACCEL=kvm TARGET=RELEASE --FlashOnly

Rename TEST_REGEX to FILE_REGEX @Javagedes (#1338)

Change Details

Description

This commit renames the TEST_REGEX command line option to FILE_REGEX and updates the logic so that files matching FILE_REGEX are always moved to the virtual drive; then if RUN_TESTS=TRUE we will treat those files as platform unit tests and will generate a startup nsh to automatically run the tests.

This makes it easy for developers to move files onto the virtual drive automatically without necessarily treating those files as on-platform unit tests.

QemuQ35 Acceleration @Flickdm (#1319)

Change Details

Description

This pull request introduces configuration changes to support QEMU acceleration mode (KVM) for the QemuQ35Pkg platform

Configuration Improvements:

• Set PcdFirstTimeWakeUpAPsBySipi to FALSE in QemuQ35PkgCommon.dsc.inc to ensure proper multi-core SMP initialization under Hyper-V nested virtualization (e.g., WSL2), addressing known issues with SIPI-only wakeup.
