From: "fweimer at redhat dot com" <sourceware-bugzilla@sourceware.org> To: glibc-bugs@sourceware.org Subject: [Bug libc/28912] New: RDPID support incorrectly reported on x86 Date: Mon, 21 Feb 2022 08:31:10 +0000 [thread overview] Message-ID: <bug-28912-131@http.sourceware.org/bugzilla/> (raw) https://sourceware.org/bugzilla/show_bug.cgi?id=28912 Bug ID: 28912 Summary: RDPID support incorrectly reported on x86 Product: glibc Version: 2.36 Status: NEW Severity: normal Priority: P2 Component: libc Assignee: unassigned at sourceware dot org Reporter: fweimer at redhat dot com CC: drepper.fsp at gmail dot com Target Milestone: --- Target: x86_64-*-linux-gnu RDPID requires that the kernel set ups an MSR before it can be used. Hardware support by itself is not enough. I think this line CPU_FEATURE_SET_ACTIVE (cpu_features, RDPID); needs to be removed from sysdeps/x86/cpu-features.c. -- You are receiving this mail because: You are on the CC list for the bug.
