2005-09-10[PATCH] remove ACPI S4bios supportPavel Machek
Remove S4BIOS support. It is pretty useless, and only ever worked for _me_ once. (I do not think anyone else ever tried it). It was in feature-removal for a long time, and it should have been removed before.

2005-09-09[PATCH] fbdev: Add VESA Coordinated Video Timings (CVT) supportAntonino A. Daplas
The Coordinated Video Timings (CVT) is the latest standard approved by VESA concerning video timings generation. It addresses the limitation of GTF which is designed mainly for CRT displays. CRT's have a high blanking requirement (as much as 25% of the horizontal frame length) which artificially increases the pixelclock. Digital displays, on the other hand, needs to conserve the pixelclock as much as possible. The GTF also does not take into account the different aspect ratios in its calculation. The new function added is fb_find_mode_cvt(). It is called by fb_find_mode() if it recognizes a mode option string formatted for CVT. The format is: <xres>x<yres>[M][R][-<bpp>][<at-sign><refresh>][i][m] The 'M' tells the function to calculate using CVT. On it's own, it will compute a timing for CRT displays at 60Hz. If the 'R' is specified, 'reduced blanking' computation will be used, best for flatpanels. The 'i' and the 'm' is for 'interlaced mode' and 'with margins' respectively. To determine if CVT was used, check for dmesg for something like this: CVT Mode - <pix>M<n>[-R], ie: .480M3-R (800x600 reduced blanking) where: pix - product of xres and yres, in MB M - is a CVT mode n - the aspect ratio (3 - 4:3; 4 - 5:4; 9 - 16:9, 15:9; A - 16:10) -R - reduced blanking Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-09[PATCH] framebuffer: new driver for cyberblade/i1 graphics coreKnut Petersen
This is a framebuffer driver for the Cyberblade/i1 graphics core. Currently tridenfb claims to support the cyberblade/i1 graphics core. This is of very limited truth. Even vesafb is faster and provides more working modes and a much better quality of the video signal. There is a great number of bugs in tridentfb ... but most often it is impossible to decide if these bugs are real bugs or if fixing them for the cyberblade/i1 core would break support for one of the other supported chips. Tridentfb seems to be unmaintained,and documentation for most of the supported chips is not available. So "fixing" cyberblade/i1 support inside of tridentfb was not an option, it would have caused numerous if(CYBERBLADEi1) else ... cases and would have rendered the code to be almost unmaintainable. A first version of this driver was published on 2005-07-31. A fix for a bug reported by Jochen Hein was integrated as well as some changes requested by Antonino A. Daplas. A message has been added to tridentfb to inform current users of tridentfb to switch to cyblafb if the cyberblade/i1 graphics core is detected. This patch is one logical change, but because of the included documentation it is bigger than 70kb.

2005-09-09[PATCH] v9fs: Documentation, Makefiles, ConfigurationEric Van Hensbergen
OVERVIEW V9FS is a distributed file system for Linux which provides an implementation of the Plan 9 resource sharing protocol 9P. It can be used to share all sorts of resources: static files, synthetic file servers (such as /proc or /sys), devices, and application file servers (such as FUSE). BACKGROUND Plan 9 (http://plan9.bell-labs.com/plan9) is a research operating system and associated applications suite developed by the Computing Science Research Center of AT&T Bell Laboratories (now a part of Lucent Technologies), the same group that developed UNIX , C, and C++. Plan 9 was initially released in 1993 to universities, and then made generally available in 1995. Its core operating systems code laid the foundation for the Inferno Operating System released as a product by Lucent Bell-Labs in 1997. The Inferno venture was the only commercial embodiment of Plan 9 and is currently maintained as a product by Vita Nuova (http://www.vitanuova.com). After updated releases in 2000 and 2002, Plan 9 was open-sourced under the OSI approved Lucent Public License in 2003. The Plan 9 project was started by Ken Thompson and Rob Pike in 1985. Their intent was to explore potential solutions to some of the shortcomings of UNIX in the face of the widespread use of high-speed networks to connect machines. In UNIX, networking was an afterthought and UNIX clusters became little more than a network of stand-alone systems. Plan 9 was designed from first principles as a seamless distributed system with integrated secure network resource sharing. Applications and services were architected in such a way as to allow for implicit distribution across a cluster of systems. Configuring an environment to use remote application components or services in place of their local equivalent could be achieved with a few simple command line instructions. For the most part, application implementations operated independent of the location of their actual resources. Commercial operating systems haven't changed much in the 20 years since Plan 9 was conceived. Network and distributed systems support is provided by a patchwork of middle-ware, with an endless number of packages supplying pieces of the puzzle. Matters are complicated by the use of different complicated protocols for individual services, and separate implementations for kernel and application resources. The V9FS project (http://v9fs.sourceforge.net) is an attempt to bring Plan 9's unified approach to resource sharing to Linux and other operating systems via support for the 9P2000 resource sharing protocol. V9FS HISTORY V9FS was originally developed by Ron Minnich and Maya Gokhale at Los Alamos National Labs (LANL) in 1997. In November of 2001, Greg Watson setup a SourceForge project as a public repository for the code which supported the Linux 2.4 kernel. About a year ago, I picked up the initial attempt Ron Minnich had made to provide 2.6 support and got the code integrated into a 2.6.5 kernel. I then went through a line-for-line re-write attempting to clean-up the code while more closely following the Linux Kernel style guidelines. I co-authored a paper with Ron Minnich on the V9FS Linux support including performance comparisons to NFSv3 using Bonnie and PostMark - this paper appeared at the USENIX/FREENIX 2005 conference in April 2005: ( http://www.usenix.org/events/usenix05/tech/freenix/hensbergen.html ). CALL FOR PARTICIPATION/REQUEST FOR COMMENTS Our 2.6 kernel support is stabilizing and we'd like to begin pursuing its integration into the official kernel tree. We would appreciate any review, comments, critiques, and additions from this community and are actively seeking people to join our project and help us produce something that would be acceptable and useful to the Linux community. STATUS The code is reasonably stable, although there are no doubt corner cases our regression tests haven't discovered yet. It is in regular use by several of the developers and has been tested on x86 and PowerPC (32-bit and 64-bit) in both small and large (LANL cluster) deployments. Our current regression tests include fsx, bonnie, and postmark. It was our intention to keep things as simple as possible for this release -- trying to focus on correctness within the core of the protocol support versus a rich set of features. For example: a more complete security model and cache layer are in the road map, but excluded from this release. Additionally, we have removed support for mmap operations at Al Viro's request. PERFORMANCE Detailed performance numbers and analysis are included in the FREENIX paper, but we show comparable performance to NFSv3 for large file operations based on the Bonnie benchmark, and superior performance for many small file operations based on the PostMark benchmark. Somewhat preliminary graphs (from the FREENIX paper) are available (http://v9fs.sourceforge.net/perf/index.html). RESOURCES The source code is available in a few different forms: tarballs: http://v9fs.sf.net CVSweb: http://cvs.sourceforge.net/viewcvs.py/v9fs/linux-9p/ CVS: :pserver:anonymous@cvs.sourceforge.net:/cvsroot/v9fs/linux-9p Git: rsync://v9fs.graverobber.org/v9fs (webgit: http://v9fs.graverobber.org) 9P: tcp!v9fs.graverobber.org!6564 The user-level server is available from either the Plan 9 distribution or from http://v9fs.sf.net Other support applications are still being developed, but preliminary version can be downloaded from sourceforge. Documentation on the protocol has historically been the Plan 9 Man pages (http://plan9.bell-labs.com/sys/man/5/INDEX.html), but there is an effort under way to write a more complete Internet-Draft style specification (http://v9fs.sf.net/rfc). There are a couple of mailing lists supporting v9fs, but the most used is v9fs-developer@lists.sourceforge.net -- please direct/cc your comments there so the other v9fs contibutors can participate in the conversation. There is also an IRC channel: irc://freenode.net/#v9fs This part of the patch contains Documentation, Makefiles, and configuration file changes.

2005-09-07[PATCH] cpusets: formalize intermediate GFP_KERNEL containmentPaul Jackson
This patch makes use of the previously underutilized cpuset flag 'mem_exclusive' to provide what amounts to another layer of memory placement resolution. With this patch, there are now the following four layers of memory placement available: 1) The whole system (interrupt and GFP_ATOMIC allocations can use this), 2) The nearest enclosing mem_exclusive cpuset (GFP_KERNEL allocations can use), 3) The current tasks cpuset (GFP_USER allocations constrained to here), and 4) Specific node placement, using mbind and set_mempolicy. These nest - each layer is a subset (same or within) of the previous. Layer (2) above is new, with this patch. The call used to check whether a zone (its node, actually) is in a cpuset (in its mems_allowed, actually) is extended to take a gfp_mask argument, and its logic is extended, in the case that __GFP_HARDWALL is not set in the flag bits, to look up the cpuset hierarchy for the nearest enclosing mem_exclusive cpuset, to determine if placement is allowed. The definition of GFP_USER, which used to be identical to GFP_KERNEL, is changed to also set the __GFP_HARDWALL bit, in the previous cpuset_gfp_hardwall_flag patch. GFP_ATOMIC and GFP_KERNEL allocations will stay within the current tasks cpuset, so long as any node therein is not too tight on memory, but will escape to the larger layer, if need be. The intended use is to allow something like a batch manager to handle several jobs, each job in its own cpuset, but using common kernel memory for caches and such. Swapper and oom_kill activity is also constrained to Layer (2). A task in or below one mem_exclusive cpuset should not cause swapping on nodes in another non-overlapping mem_exclusive cpuset, nor provoke oom_killing of a task in another such cpuset. Heavy use of kernel memory for i/o caching and such by one job should not impact the memory available to jobs in other non-overlapping mem_exclusive cpusets. This patch enables providing hardwall, inescapable cpusets for memory allocations of each job, while sharing kernel memory allocations between several jobs, in an enclosing mem_exclusive cpuset. Like Dinakar's patch earlier to enable administering sched domains using the cpu_exclusive flag, this patch also provides a useful meaning to a cpuset flag that had previously done nothing much useful other than restrict what cpuset configurations were allowed.

2005-09-07[PATCH] Add rdinit parameter to pick early userspace initOlof Johansson
Since early userspace was added, there's no way to override which init to run from it. Some people tack on an extra cpio archive with a link from /init depending on what they want to run, but that's sometimes impractical. Changing the "init=" to also override the early userspace isn't feasible, since it is still used to indicate what init to run from disk when early userspace has completed doing whatever it's doing (i.e. load filesystem modules and drivers). Instead, introduce "rdinit=" and make it override the default "/init" if specified.

2005-09-07[PATCH] sonypi SPIC initialisation fixErik Waling
Newer Sony VAIO models (VGN-S480, VGN-S460, VGN-S3XP etc) use a new method to initialize the SPIC device. The new way to initialize (and disable) the device comes directly from the AML code in the _CRS, _SRS and _DIS methods from the DSDT table. This patch adds support for the new models.

2005-09-07[PATCH] NMI: Update NMI users of RCU to use new APIPaul E. McKenney
Uses of RCU for dynamically changeable NMI handlers need to use the new rcu_dereference() and rcu_assign_pointer() facilities. This change makes it clear that these uses are safe from a memory-barrier viewpoint, but the main purpose is to document exactly what operations are being protected by RCU. This has been tested on x86 and x86-64, which are the only architectures affected by this change.

2005-09-07[PATCH] relayfsTom Zanussi
Here's the latest version of relayfs, against linux-2.6.11-mm2. I'm hoping you'll consider putting this version back into your tree - the previous rounds of comment seem to have shaken out all the API issues and the number of comments on the code itself have also steadily dwindled. This patch is essentially the same as the relayfs redux part 5 patch, with some minor changes based on reviewer comments. Thanks again to Pekka Enberg for those. The patch size without documentation is now a little smaller at just over 40k. Here's a detailed list of the changes: - removed the attribute_flags in relay open and changed it to a boolean specifying either overwrite or no-overwrite mode, and removed everything referencing the attribute flags. - added a check for NULL names in relayfs_create_entry() - got rid of the unnecessary multiple labels in relay_create_buf() - some minor simplification of relay_alloc_buf() which got rid of a couple params - updated the Documentation In addition, this version (through code contained in the relay-apps tarball linked to below, not as part of the relayfs patch) tries to make it as easy as possible to create the cooperating kernel/user pieces of a typical and common type of logging application, one where kernel logging is kicked off when a user space data collection app starts and stops when the collection app exits, with the data being automatically logged to disk in between. To create this type of application, you basically just include a header file (relay-app.h, included in the relay-apps tarball) in your kernel module, define a couple of callbacks and call an initialization function, and on the user side call a single function that sets up and continuously monitors the buffers, and writes data to files as it becomes available. Channels are created when the collection app is started and destroyed when it exits, not when the kernel module is inserted, so different channel buffer sizes can be specified for each separate run via command-line options. See the README in the relay-apps tarball for details. Also included in the relay-apps tarball are a couple examples demonstrating how you can use this to create quick and dirty kernel logging/debugging applications. They are: - tprintk, short for 'tee printk', which temporarily puts a kprobe on printk() and writes a duplicate stream of printk output to a relayfs channel. This could be used anywhere there's printk() debugging code in the kernel which you'd like to exercise, but would rather not have your system logs cluttered with debugging junk. You'd probably want to kill klogd while you do this, otherwise there wouldn't be much point (since putting a kprobe on printk() doesn't change the output of printk()). I've used this method to temporarily divert the packet logging output of the iptables LOG target from the system logs to relayfs files instead, for instance. - klog, which just provides a printk-like formatted logging function on top of relayfs. Again, you can use this to keep stuff out of your system logs if used in place of printk.
