Subject: [PATCH]powerpc/xive: Export XIVE IPI information for online-only processors.
Date: Thu, 06 Jan 2022 16:33:53 +0530 [thread overview]
Message-ID: <164146703333.19039.10920919226094771665.sendpatchset@MacBook-Pro.local> (raw)
[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 815 bytes --]
Cédric pointed out that XIVE IPI information exported via sysfs
(debug/powerpc/xive) display empty lines for processors which are
not online.
Switch to using for_each_online_cpu() so that information is
displayed for online-only processors.
