I also forgot to indicate the qemu-user-static vintage = relationship.] I had been reporting intermittent hang-ups for my amd64->{aarch64,armv7} = port cross builds in another message sequence. But it turns out that one thing I = ran into has hung-up every time, the same way, for amd64->armv7 cross builds: multimedia/gstreamer1-qt@qt5 . So I extract the material here into a = separate report with some updated notes. A little context: I had built from ports head -r484783 before under = FreeBSD head -r340287 (as I remember the version). Back then it did not have this = problem that it now has under FreeBSD head -r341836 . One ports-specific change was to = force perl5.28 as the default instead of perl5.26 originally. In fact this is what = drives what is being rebuilt for my experiment that caught this. But I doubt the perl = version is important to the problem. The context has a Ryzen Threadripper 1950X and = has been tested both for FreeBSD under Hyper-V and for the same media = native-booted. Both hang-up at the same point as seen via ps or top. The native tools for = cross-build speedup were in use. Cross-builds targeting aarch64 did not get this = problem but targeting armv7 did. 121 of 129 armv7 ports built before the hang-up for = the first armv7 try. ADDED: The qemu-user-static back with head -r340287 before installing = the updated ports would likely be different than the -r484783 vintage. So = both FreeBSD and qemu-user-static may have changed over the comparison. The hang-up: In the port rebuilds targeting armv7, multimedia/gstreamer1-qt@qt5 = hung-up and timed out. Looking during the wait in later tries shows something much like = (from one of the examples): root 33719 0.0 0.0 12920 3528 0 I 11:40 0:00.03 | = | `-- sh: poudriere[FBSDFSSDjailArmV7-default][02]: build_pkg = (gstreamer1-qt5-1.2.0_14) (sh) root 41551 0.0 0.0 12920 3520 0 I 11:43 0:00.00 | = | `-- sh: poudriere[FBSDFSSDjailArmV7-default][02]: = build_pkg (gstreamer1-qt5-1.2.0_14) (sh) root 41552 0.0 0.0 10340 1744 0 IJ 11:43 0:00.01 | = | `-- /usr/bin/make -C /usr/ports/multimedia/gstreamer1-qt = FLAVOR=3Dqt5 build root 41566 0.0 0.0 10236 1796 0 IJ 11:43 0:00.00 | = | `-- /bin/sh -e -c (cd = /wrkdirs/usr/ports/multimedia/gstreamer1-qt/work-qt5/.build; if ! = /usr/bin/env QT_SELE root 41567 0.0 0.0 89976 12896 0 IJ 11:43 0:00.07 | = | `-- /usr/local/bin/qemu-arm-static ninja -j28 -v all root 41585 0.0 0.0 102848 25056 0 IJ 11:43 0:00.10 | = | |-- /usr/local/bin/qemu-arm-static = /usr/local/bin/cmake -E cmake_autogen /wrkdirs/usr/ports/multimedia/g root 41586 0.0 0.0 102852 25072 0 IJ 11:43 0:00.11 | = | `-- /usr/local/bin/qemu-arm-static = /usr/local/bin/cmake -E cmake_autogen /wrkdirs/usr/ports/multimedia/g or as top showed it: 41552 root 1 52 0 10M 1744K 0 wait 15 0:00 = 0.00% /usr/bin/make -C /usr/ports/multimedia/gstreamer1-qt FLAVOR=3Dqt5 = build 41566 root 1 52 0 10M 1796K 0 wait 1 0:00 = 0.00% /bin/sh -e -c (cd = /wrkdirs/usr/ports/multimedia/gstreamer1-qt/work-qt5/.build; if ! = /usr/bin/env QT_SELECT=3Dqt5 QMAKEMODULES 41567 root 2 52 0 88M 13M 0 select 4 0:00 = 0.00% /usr/local/bin/qemu-arm-static ninja -j28 -v all 41585 root 2 52 0 100M 24M 0 kqread 8 0:00 = 0.00% /usr/local/bin/qemu-arm-static /usr/local/bin/cmake -E = cmake_autogen /wrkdirs/usr/ports/multimedia/gstreamer1-qt/work-qt5/. 41586 root 2 52 0 100M 24M 0 kqread 22 0:00 = 0.00% /usr/local/bin/qemu-arm-static /usr/local/bin/cmake -E = cmake_autogen /wrkdirs/usr/ports/multimedia/gstreamer1-qt/work-qt5/. So: waiting in kqread trying to run cmake. Unlike some intermittent hang-ups, attaching-then-detaching via gdb does = not resume the hung-up processes. Kills of the processes waiting on kqread = stop the build. Given the prior ports have been built already, building just multimedia/gstreamer1-qt@qt5 still gets the hang-up at the same point. Building anything that requires multimedia/gstreamer1-qt@qt5 seems to be solidly blocked in my environment. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
