Subject: [PATCH 0/5] Support 64K pages mapping of SPE local stores on 4K kernel
Date: Tue, 20 Feb 2007 18:44:12 +1100	[thread overview]
Message-ID: <1171957452.861958.803775545202.qpush@grosgo> (raw)

This serie of patches supports userland mappings of SPE local stores
using 64K hardware pages rather than 4K on a kernel using 4K pages to
improve performances.

The current version of this serie relies on a hack to the generic code
which is probably not acceptable upsteam. I have plans to do a proper
fix but haven't had time to do it yet.

The first patch of the serie is fairly independant of the rest and
should be applied to 2.6.21 as I beleive it fixes a bug with handling
of huge pages from SPEs.
