[OS-BUILD PATCHv2] tools/power/x86/intel-speed-select: fix build failure when using -Wl,--as-needed
by Prarit Bhargava (via Email Bridge) 06 Apr '22

From: Prarit Bhargava <prarit(a)redhat.com> tools/power/x86/intel-speed-select: fix build failure when using -Wl,--as-needed Upstream Status: https://www.spinics.net/lists/platform-driver-x86/msg31958.html Build of intel-speed-select will fail if you run: $ LDFLAGS="-Wl,--as-needed" /usr/bin/make V=1 ... gcc -O2 -Wall -g -D_GNU_SOURCE -Iinclude -I/usr/include/libnl3 -Wl,--as-needed -lnl-genl-3 -lnl-3 intel-speed-select-in.o -o intel-speed-select /usr/bin/ld: intel-speed-select-in.o: in function `handle_event': (...)/linux/tools/power/x86/intel-speed-select/hfi-events.c:189: undefined reference to `nlmsg_hdr' ... In this case the problem is that order when linking matters when using the flag -Wl,--as-needed, symbols not used at that point are discarded. So since intel-speed-select-in.o comes after, at that point the libraries/symbols are already discarded and then missing/undefined references are reported. To fix this, make sure we specify LDFLAGS after the object file. Signed-off-by: Herton R.

[OS-BUILD PATCH] redhat: indicate HEAD state in tarball/rpm name
by Jarod Wilson (via Email Bridge) 05 Apr '22

05 Apr '22

From: Jarod Wilson <jarod(a)redhat.com> redhat: indicate HEAD state in tarball/rpm name For the non-Fedora (RHEL) case, we are looking to move to a setup where we include Merge Requests as soon as they are ready, and thus the head of main may not always be a tagged build. This gives some indication to someone basing a build on main that they're basing their work on the tree at a state between tagged builds. If HEAD is a tagged build, as usual, you should see: linux-4.18.0-374.el8.tar.xz kernel-4.18.0-374.el8.src.rpm If HEAD has additional commits, with this change, you should see: linux-4.18.0-374.p1.g797fdad2a6e5.el8.tar.xz kernel-4.18.0-374.p1.g797fdad2a6e5.el8.src.rpm The .pX field is "X patches since tag" and the .gSHA field is the HEAD sha of the branch after adding your local changes.

Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.
