This implements a RAM based block device which acts as swap disk. Pages swapped to this disk are compressed and stored in memory itself. This allows more applications to fit in given amount of memory. This is especially useful for embedded devices, OLPC and small desktops (aka virtual machines). Project home: http://code.google.com/p/compcache/ It consists of following components: - compcache.ko: Creates RAM based block device - tlsf.ko: Two Level Segregate Fit (TLSF) allocator - LZO de/compressor: (Already in mainline) Project home contains some performance numbers for TLSF and LZO. For general desktop use, this is giving *significant* performance gain under memory pressure. For now, it has been tested only on x86. Thanks, Nitin From mboxrd@z Thu Jan 1 00:00:00 1970 Received: by wa-out-1112.google.com with SMTP id m33so2962407wag.8 for ; Mon, 24 Mar 2008 08:04:52 -0700 (PDT) From: Nitin Gupta Reply-To: nitingupta910@gmail.com Subject: [PATCH 0/6]: compcache: Compressed Caching Date: Mon, 24 Mar 2008 20:30:05 +0530 MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Content-Disposition: inline Message-Id: <200803242030.05997.nitingupta910@gmail.com> Sender: owner-linux-mm@kvack.org Return-Path: To: linux-kernel@vger.kernel.org Cc: linux-mm@kvack.org List-ID: Hi All, (sending to lkml since I didn't get any reply at linux-mm).
