Message-ID: <37de872b0894b21408754ae2903b7701cc6dfab7.1726268190.git.jpoimboe@kernel.org> Date: Sat, 14 Sep 2024 01:02:06 +0200 From: Josh Poimboeuf <jpoimboe@...nel.org> To: x86@...nel.org Cc: Peter Zijlstra <peterz@...radead.org>, Steven Rostedt <rostedt@...dmis.org>, Ingo Molnar <mingo@...nel.org>, Arnaldo Carvalho de Melo <acme@...nel.org>, linux-kernel@...r.kernel.org, Indu Bhagat <indu.bhagat@...cle.com>, Mark Rutland <mark.rutland@....com>, Alexander Shishkin <alexander.shishkin@...ux.intel.com>, Jiri Olsa <jolsa@...nel.org>, Namhyung Kim <namhyung@...nel.org>, Ian Rogers <irogers@...gle.com>, Adrian Hunter <adrian.hunter@...el.com>, linux-perf-users@...r.kernel.org, Mark Brown <broonie@...nel.org>, linux-toolchains@...r.kernel.org, Jordan Rome <jordalgo@...a.com>, Sam James <sam@...too.org> Subject: [PATCH v2 04/11] unwind/x86/64: Add HAVE_USER_UNWIND_SFRAME Binutils 2.41 supports generating sframe v2 for x86_64. It works well in testing so enable it. NOTE: An out-of-tree glibc patch is still needed to enable setting PR_ADD_SFRAME for shared libraries and dlopens.
