Subject: [Patch 07/25] GRU - add context lock flag to gru status
Date: Thu, 26 Aug 2010 08:19:44 -0500 [thread overview]
Message-ID: <20100826132124.087884614@sgi.com> (raw)
In-Reply-To: 20100826131937.108920216@sgi.com
[-- Attachment #1: uv_gru_proc_cch_locked --]
[-- Type: text/plain, Size: 1660 bytes --]
From: Jack Steiner <steiner@sgi.com>
Add a flag to the GRU cch_status file to indicate if the cch is locked.
This is useful for debugging.
