Message-ID: <20090514232716.310530@gmx.net> Date: Fri, 15 May 2009 01:27:16 +0200 From: "Andrew Flach" <Andrew.Flach23@....at> To: linux-kernel@...r.kernel.org Subject: Uncacheable memory Hi all, For some simple tests I would like to specify some regions of an application program as uncacheable. For example, the application contains a function that maps to the memory address space 0x08002000 to 0x0800A000 in the executable. When this program is run, code within this address space should be marked as uncacheable and the Kernel should not store any data between 0x08002000 and 0x0800A000 in the cache. Is there an straightforward way to do that? Could this be realised with the PAT or do I need to have a look at the MTTR?
