Source: glibc Version: 2.31-2 Severity: wishlist User: devel@kali.org Usertags: origin-kali X-Debbugs-Cc: steev@kali.org, rbalint@ubuntu.com Hello, in Kali we are providing many images for ARM devices and some of the ARM devices that we support have support for the LSE (Large System Extensions) atomics. We would like to be able use a version of glibc with LSE support enabled to see whether we can get better performances. Ubuntu is already shipping a libc6-lse package on arm64 and it would be nice if Debian could do the same. Balint Reczey (in CC) implemented the support in Ubuntu, maybe he can share some hints on what's involved and whether we should expect some related issues. The patch used by Ubuntu looks like this one: https://git.launchpad.net/ubuntu/+source/glibc/commit/?id=d38433a40db82a14c006bb9f411d9fc22b594fa4 (except the hunk on debian/testsuite-xfail-debian.mk which is the other change in that same upload) Can you consider applying a similar change? Thank you in advance for your feedback. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (500, 'oldstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-6-amd64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_WARN, TAINT_UNSIGNED_MODULE Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled

Since glibc 2.31-0experimental2, Debian supports LSE on arm64 transparently using the -moutline-atomics option of GCC. Therefore there is no plan to add a libc6-lse package in Debian (see bug #956418 for the corresponding discussion). I am therefore closing the bug.
