pvmfw: Print RebootReason on secondary UART
When rebooting due to a business logic error, print the reason as a
formatted string to a dedicated UART, in the same way Microdroid does it
on its /dev/tty1, to provide the host with extra information about the
reason for the pVM rebooting.
Since aosp/2646391, all the pvmfw code runs with the UART properly
initialized, which greatly simplifies printing of the reboot reason as
start() can now assume that the secondary UART is also ready to be used.
This CL was verified through the logs of virtualizationmanager e.g. in
MicrodroidHostTests#protectedVmWithImageSignedWithDifferentKeyRunsPvmfw:
virtmgr : virtualizationmanager::crosvm: VM returned failure reason 'PVM_FIRMWARE_PAYLOAD_VERIFICATION_FAILED'
Note that the host still has to be taught about the new PVM_FIRMWARE_*.
Bug: 300636104
Test: atest MicrodroidHostTestCases

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.
Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.
If you want a quick start, see the getting started guideline and follow the steps there.
