[Qemu-devel] [PATCH v2 2/4] BootLinuxConsoleTest: Test nanoMIPS kernels


From: Philippe Mathieu-Daudé
Subject: [Qemu-devel] [PATCH v2 2/4] BootLinuxConsoleTest: Test nanoMIPS kernels on the I7200 CPU
Date: Thu, 23 May 2019 18:18:30 +0200

Similar to the x86_64/pc test, it boots a Linux kernel on a Malta
machine and verify the serial is working.

Use the documentation added in commit f7d257cb4a17 to test
nanoMIPS kernels and the I7200 CPU.

This test can be run using:
