After glibc uprev 2.31 -> 2.32, the following drd ptests fail with the error "condition variable has not been initialized". drd/tests/annotate_hb_err drd/tests/annotate_sem drd/tests/annotate_rwlock drd/tests/annotate_order_2 drd/tests/annotate_smart_pointer drd/tests/annotate_spinlock drd/tests/monitor_example drd/tests/pth_cond_race drd/tests/pth_inconsistent_cond_wait In glibc 2.32, the POSIX thread functions are in both libc and libpthread, causing valgrind to misinterpert test behaviour. This patch tells valgrind to intercept both the libc and the libpthread functions, resolving these ptest failures. Here are the latest test results on qemux86-64: === Test Summary === TOTAL: 728 PASSED: 688 FAILED: 1 SKIPPED: 39 The failed test is in helgrind: FAIL: helgrind/tests/pth_destroy_cond Patch can be removed once we uprev valgrind. See valgrind commit 15330adf7c2471fbaa6a0818db07078d81dbff97.

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.
