From b910545fbf3f55f22545c202c1aee62598edb838 Mon Sep 17 00:00:00 2001 From: Cleber Rosa Date: Tue, 12 Mar 2019 13:18:10 -0400 Subject: [PATCH] tests/acceptance: look for target architecture in test tags first A test can, optionally, be tagged for one or many architectures. If a test has been tagged for a single architecture, there's a high chance that the test won't run on other architectures. This changes the default order of choosing a default target architecture to use based on the 'arch' tag value first. The precedence order is for choosing a QEMU binary to use for a test is now: * qemu_bin parameter * arch parameter * arch tag value (for example, x86_64 if ":avocado: tags=arch:x86_64 is used) This means that if one runs: $ avocado run -p qemu_bin=/usr/bin/qemu-system-x86_64 test.py No arch parameter or tag will influence the selection of the QEMU target binary. If one runs: $ avocado run -p arch=ppc64 test.py The target binary selection mechanism will attempt to find a binary such as "ppc64-softmmu/qemu-system-ppc64". And finally, if one runs a test that is tagged (in its docstring) with "arch:aarch64": $ avocado run aarch64.py The target binary selection mechanism will attempt to find a binary such as "aarch64-softmmu/qemu-system-aarch64". At this time, no provision is made to cancel the execution of tests if the arch parameter given (manually) does not match the test "arch" tag, but it may be a useful default behavior to be added in the future.
