Created attachment 921475 [details, diff] All commits between the 5.2 release tag and the latest available at time of writing (ee482f311) on the master branch. Supports Linux 6.13. Systemstap 5.2 is broken by Linux 6.13 (upstream is aware og this). Any attempt to compile a systemtap script under a Linux 6.13 kernel miserably fails like this: # stap -d /lib/modules/6.13.7-gentoo/kernel/drivers/gpu/drm/imagination/powervr.ko --ldd mod_powervr_empty.stp <command-line>: fatal error: /tmp/stapNB9Wvg/stapconf_203adc11d41bf5a9ae9020d0784199e7_740.h: No such file or directory <command-line>: fatal error: /tmp/stapNB9Wvg/stapconf_203adc11d41bf5a9ae9020d0784199e7_740.h: No such file or directory compilation terminated. compilation terminated. make[2]: *** [/usr/src/linux-6.13.7-gentoo/scripts/Makefile.build:196: stap_ebf0257f6fcb955c562f753025896ea4_1322_src.o] Error 1 make[2]: *** Waiting for unfinished jobs.... make[2]: *** [/usr/src/linux-6.13.7-gentoo/scripts/Makefile.build:196: stap_ebf0257f6fcb955c562f753025896ea4_1322_aux_0.o] Error 1 <command-line>: fatal error: /tmp/stapNB9Wvg/stapconf_203adc11d41bf5a9ae9020d0784199e7_740.h: No such file or directory compilation terminated. make[2]: *** [/usr/src/linux-6.13.7-gentoo/scripts/Makefile.build:196: stap_symbols.o] Error 1 make[1]: *** [/usr/src/linux-6.13.7-gentoo/Makefile:1991: .] Error 2 make: *** [Makefile:251: __sub-make] Error 2 WARNING: kbuild exited with status: 2 Pass 4: compilation failed.

Systemtap compiles and works fine on my AMD64 and RISC-V machines all running under =sys-kernel/gentoo-sources-6.13.7. Used patchset attached for the convenience.
Yeah, I think we should really consider regularly doing snapshots for systemtap.
