Small IGVM file bundles required for tesing vm-launch-update device
===================================================================

This directory contains IGVM files required for launchupdate-test.c.
These IGVM bundles can be built from the following repository:

https://gitlab.com/anisinha/virt-firmware-rs

Just type "make" in the top of the repository. The built IGVM files
can be found in the target/x86_64-unknown-none/debug directory.

$ ls -l ./target/x86_64-unknown-none/debug/*.igvm
-rw-r--r--. 1 anisinha anisinha 153624 Jun  8 10:05 ./target/x86_64-unknown-none/debug/hello.igvm
-rw-r--r--. 1 anisinha anisinha 157848 Jun  8 10:05 ./target/x86_64-unknown-none/debug/igvmtest.igvm
-rw-r--r--. 1 anisinha anisinha 987384 Jun  8 10:05 ./target/x86_64-unknown-none/debug/mefisto.igvm
-rw-r--r--. 1 anisinha anisinha 368312 Jun  8 10:05 ./target/x86_64-unknown-none/debug/qemuinit.igvm
-rw-r--r--. 1 anisinha anisinha 223944 Jun  8 10:05 ./target/x86_64-unknown-none/debug/snptest.igvm

The IGVM bundles for sev-snp testing are also kept in a seperate directory /snp_igvm_bundles in the
above repository for use without requiring to build from source:

$ virtfirmware-rs/snp_igvm_bundles$ ls -l
total 388
-rw-r--r-- 1 anisinha anisinha 199176 Aug  7 00:58 snptest.igvm
-rw-r--r-- 1 anisinha anisinha 195048 Aug  6 06:10 snptest-nohello.igvm

Following files are used by the tests/qtest/launchupdate-test.c for non-coco case:

hello.igvm
qemuinit.igvm

For confidential case (that is when COCO=1 is passed in the environment), the following
IGVM bundles are used:

snptest-nohello.igvm
snptest.igvm

The IGVM bundles used by the confidential case are not checked into the QEMU
repository. Users who wish to test the confidential case can use the IGVM
bundles from https://gitlab.com/anisinha/virt-firmware-rs as mentioned above.
