Subject: [patch 10/20] spufs: fix initial state of wbox file
Date: Mon, 19 Jun 2006 20:33:25 +0200 [thread overview]
Message-ID: <20060619183405.408643000@klappe.arndb.de> (raw)
In-Reply-To: 20060619183315.653672000@klappe.arndb.de
The wbox channel count of an spu is now initialized
to four for the saved context. This makes it possible
to write to the mailbox right away without waiting
for the SPE to become scheduled first.
