Multiple patches are to be applied to improve the current ptest suite. 0001-Fix-tests-link-libpause_consumer-on-liblttng-ctl.patch 0002-Fix-test-skip-test_getcpu_override-on-single-thread-.patch 0003-Fix-test-unit-the-tree-origin-can-be-a-symlink-itsel.patch 0006-Tests-check-for-lttng-modules-presence.patch All deal with problem in the test suite. Most of these are already accepted upstream and will be removed on the next recipe update. 0004-Skip-when-testapp-is-not-present.patch Is a OE specific fix that make sure that we skip the test if the test util application (event generator) is not present. We are still unsure on how (upstream) we are going to solve this problem. We already have this problem if a user build lttng without lttng-ust (--without-lttng-ust). We will most probably end up splitting each test into kernel and userspace tests and adjust the makefile accordingly. Another option is to probe lttng for enabled function at runtime. 0005-Tests-use-modprobe-to-test-for-the-presence-of-lttng.patch Is a requirement for 0006 that should be accepted upstream shorlty. 0007-Fix-getgrnam-is-not-MT-Safe-use-getgrnam_r.patch Fixes a race found while testing OE built with musl. This is a legit bug. The fixes or a variant should be accepted soon.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
