From 5d35634ecc2d2c3938bd7dc23df0ad046da1b303 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 22 Oct 2024 17:22:36 -0300 Subject: [PATCH] perf trace: Fix non-listed archs in the syscalltbl routines This fixes a build breakage on 32-bit arm, where the syscalltbl__id_at_idx() function was missing. Committer notes: Generating a proper syscall table from a copy of arch/arm/tools/syscall.tbl ends up being too big a patch for this rc stage, I started doing it but while testing noticed some other problems with using BPF to collect pointer args on arm7 (32-bit) will maybe continue trying to make it work on the next cycle...
