Subject: [PATCH 0/1] speeding up cpu_up()
Date: Sat, 18 Apr 2015 20:53:14 -0400	[thread overview]
Message-ID: <1429404795-23260-1-git-send-email-lenb@kernel.org> (raw)

The following patch...

[PATCH 1/1] x86: replace cpu_up hard-coded mdelay with variable

enables reducing cpu_up() time by 10ms on modern systems.

This means that for every processor in the system,
boot-time and resume-time can be reduced by 10ms per-processor.

Once this patch is accepted, I'll send a subsequent patch
to update the default delay, as appropriate.

thanks,
Len Brown, Intel Open Source Technology Center
