From dce900b029607d12ad55de35741f245beb409b47 Mon Sep 17 00:00:00 2001 From: Mikko Rapeli Date: Tue, 3 Jun 2025 15:29:39 +0300 Subject: [PATCH] oeqa selftest uboot.py: add qemu KVM test case Add a test case to boot target system via u-boot using qemu with KVM. This was broken recently and workaround proposed to u-boot. Test case works with genericarm64 and qemuarm64 target machines compiled and tested on aarch64 build host with KVM support. Test execution time with full sstate cache is around 170 seconds. qemu boot itself takes just a few seconds to full userspace.
