It is used along + with gdb to debug a linux kernel. The expectation is that gdb can + be used to "break in" to the kernel to inspect memory, variables + and look through a cal stack information similar to what an + application developer would use gdb for. It is possible to place + breakpoints in kernel code and perform some limited execution + stepping. + + + Two machines are required for using kgdb. One of these machines is a + development machine and the other is a test machine. The kernel + to be debugged runs on the test machine. The development machine + runs an instance of gdb against the vmlinux file which contains + the symbols (not boot image such as bzImage, zImage, uImage...). + In gdb the developer specifies the connection parameters and + connects to kgdb. Depending on which kgdb I/O modules exist in + the kernel for a given architecture, it may be possible to debug + the test machine's kernel with the development machine using a + rs232 or ethernet connection. + + + + Compiling a kernel + + To enable CONFIG_KGDB, look under the "Kernel debugging" + and then select "KGDB: kernel debugging with remote gdb". + + + Next you should choose one of more I/O drivers to interconnect debugging + host and debugged target. Early boot debugging requires a KGDB + I/O driver that supports early debugging and the driver must be + built into the kernel directly. Kgdb I/O driver configuration + takes place via kernel or module parameters, see following + chapter. + + + The kgdb test compile options are described in the kgdb test suite chapter. + + + + + Enable kgdb for debugging + + In order to use kgdb you must activate it by passing configuration + information to one of the kgdb I/O drivers. If you do not pass any + configuration information kgdb will not do anything at all. Kgdb + will only actively hook up to the kernel trap hooks if a kgdb I/O + driver is loaded and configured. If you unconfigure a kgdb I/O + driver, kgdb will unregister all the kernel hook points. + + + All drivers can be reconfigured at run time, if + CONFIG_SYSFS and CONFIG_MODULES + are enabled, by echo'ing a new config string to + /sys/module/<driver>/parameter/<option>. + The driver can be unconfigured by passing an empty string. You cannot + change the configuration while the debugger is attached. Make sure + to detach the debugger with the detach command + prior to trying unconfigure a kgdb I/O driver. + + + Kernel parameter: kgdbwait + + The Kernel command line option kgdbwait makes + kgdb wait for a debugger connection during booting of a kernel. You + can only use this option you compiled a kgdb I/O driver into the + kernel and you specified the I/O driver configuration as a kernel + command line option. The kgdbwait parameter should always follow the + configuration parameter for the kgdb I/O driver in the kernel + command line else the I/O driver will not be configured prior to + asking the kernel to use it to wait. + + + The kernel will stop and wait as early as the I/O driver and + architecture will allow when you use this option. If you build the + kgdb I/O driver as a kernel module kgdbwait will not do anything. + + + + Kernel parameter: kgdboc + + The kgdboc driver was originally an abbreviation meant to stand for + "kgdb over console". Kgdboc is designed to work with a single + serial port. It was meant to cover the circumstance + where you wanted to use a serial console as your primary console as + well as using it to perform kernel debugging. Of course you can + also use kgdboc without assigning a console to the same port. + + + Using kgdboc + + You can configure kgdboc via sysfs or a module or kernel boot line + parameter depending on if you build with CONFIG_KGDBOC as a module + or built-in. + + From the module load or build-in + kgdboc=<tty-device>,[baud] + + The example here would be if your console port was typically ttyS0, you would use something like kgdboc=ttyS0,115200 or on the ARM Versatile AB you would likely use kgdboc=ttyAMA0,115200 + + + From sysfs + echo ttyS0 > /sys/module/kgdboc/parameters/kgdboc + + + + + NOTE: Kgdboc does not support interrupting the target via the + gdb remote protocol. You must manually send a sysrq-g unless you + have a proxy that splits console output to a terminal problem and + has a separate port for the debugger to connect to that sends the + sysrq-g for you. + + When using kgdboc with no debugger proxy, you can end up + connecting the debugger for one of two entry points. If an + exception occurs after you have loaded kgdboc a message should print + on the console stating it is waiting for the debugger. In case you + disconnect your terminal program and then connect the debugger in + its place. If you want to interrupt the target system and forcibly + enter a debug session you have to issue a Sysrq sequence and then + type the letter g. Then you disconnect the + terminal session and connect gdb. Your options if you don't like + this are to hack gdb to send the sysrq-g for you as well as on the + initial connect, or to use a debugger proxy that allows an + unmodified gdb to do the debugging. + + + + + Kernel parameter: kgdbcon + + Kgdb supports using the gdb serial protocol to send console messages + to the debugger when the debugger is connected and running. There + are two ways to activate this feature. + + Activate with the kernel command line option: + kgdbcon + + Use sysfs before configuring an io driver + + echo 1 > /sys/module/kgdb/parameters/kgdb_use_con + + + NOTE: If you do this after you configure the kgdb I/O driver, the + setting will not take effect until the next point the I/O is + reconfigured. + + + + + + IMPORTANT NOTE: Using this option with kgdb over the console + (kgdboc) or kgdb over ethernet (kgdboe) is not supported. + + + + + Connecting gdb + + If you are using kgdboc, you need to have used kgdbwait as a boot + argument, issued a sysrq-g, or the system you are going to debug + has already taken an exception and is waiting for the debugger to + attach before you can connect gdb. + + + If you are not using different kgdb I/O driver other than kgdboc, + you should be able to connect and the target will automatically + respond. + + + Example (using a serial port): + + + % gdb ./vmlinux + (gdb) set remotebaud 115200 + (gdb) target remote /dev/ttyS0 + + + Example (kgdb to a terminal server): + + + % gdb ./vmlinux + (gdb) target remote udp:192.168.2.2:6443 + + + Example (kgdb over ethernet): + + + % gdb ./vmlinux + (gdb) target remote udp:192.168.2.2:6443 + + + Once connected, you can debug a kernel the way you would debug an + application program. + + + If you are having problems connecting or something is going + seriously wrong while debugging, it will most often be the case + that you want to enable gdb to be verbose about its target + communications. You do this prior to issuing the target + remote command by typing in: set remote debug 1 + + + + kgdb Test Suite + + When kgdb is enabled in the kernel config you can also elect to + enable the config parameter KGDB_TESTS. Turning this on will + enable a special kgdb I/O module which is designed to test the + kgdb internal functions. + + + The kgdb tests are mainly intended for developers to test the kgdb + internals as well as a tool for developing a new kgdb architecture + specific implementation. These tests are not really for end users + of the Linux kernel. The primary source of documentation would be + to look in the drivers/misc/kgdbts.c file. + + + The kgdb test suite can also be configured at compile time to run + the core set of tests by setting the kernel config parameter + KGDB_TESTS_ON_BOOT. This particular option is aimed at automated + regression testing and does not require modifying the kernel boot + config arguments. If this is turned on, the kgdb test suite can + be disabled by specifying "kgdbts=" as a kernel boot argument. + + + + KGDB Internals + + Architecture Specifics + + Kgdb is organized into three basic components: + + kgdb core + + The kgdb core is found in kernel/kgdb.c. It contains: + + All the logic to implement the gdb serial protocol + A generic OS exception handler which includes sync'ing the processors into a stopped state on an multi cpu system. + The API to talk to the kgdb I/O drivers + The API to make calls to the arch specific kgdb implementation + The logic to perform safe memory reads and writes to memory while using the debugger + A full implementation for software breakpoints unless overridden by the arch + + + + kgdb arch specific implementation + + This implementation is generally found in arch/*/kernel/kgdb.c. + As an example, arch/x86/kernel/kgdb.c contains the specifics to + implement HW breakpoint as well as the initialization to + dynamically register and unregister for the trap handlers on + this architecture. The arch specific portion implements: + + contains an arch specific trap catcher which + invokes kgdb_handle_exception() to start kgdb about doing its + work + translation to and from gdb specific packet format to pt_regs + Registration and unregistration of architecture specific trap hooks + Any special exception handling and cleanup + NMI exception handling and cleanup + (optional)HW breakpoints + + + + kgdb I/O driver + + Each kgdb I/O driver has to provide an implemenation for the following: + + configuration via builtin or module + dynamic configuration and kgdb hook registration calls + read and write character interface + A cleanup handler for unconfiguring from the kgdb core + (optional) Early debug methodology + + Any given kgdb I/O driver has to operate very closely with the + hardware and must do it in such a way that does not enable + interrupts or change other parts of the system context without + completely restoring them. The kgdb core will repeatedly "poll" + a kgdb I/O driver for characters when it needs input. The I/O + driver is expected to return immediately if there is no data + available. Doing so allows for the future possibility to touch + watch dog hardware in such a way as to have a target system not + reset when these are enabled. + + + + + + If you are intent on adding kgdb architecture specific support + for a new architecture, the architecture should define + HAVE_ARCH_KGDB in the architecture specific + Kconfig file. This will enable kgdb for the architecture, and + at that point you must create an architecture specific kgdb + implementation. + + + There are a few flags which must be set on every architecture in + their <asm/kgdb.h> file. These are: + + + + NUMREGBYTES: The size in bytes of all of the registers, so + that we can ensure they will all fit into a packet. + + + BUFMAX: The size in bytes of the buffer GDB will read into. + This must be larger than NUMREGBYTES. + + + CACHE_FLUSH_IS_SAFE: Set to 1 if it is always safe to call + flush_cache_range or flush_icache_range. On some architectures, + these functions may not be safe to call on SMP since we keep other + CPUs in a holding pattern. + + + + + + There are also the following functions for the common backend, + found in kernel/kgdb.c, that must be supplied by the + architecture-specific backend unless marked as (optional), in + which case a default function maybe used if the architecture + does not need to provide a specific implementation. + +!Iinclude/linux/kgdb.h + + + kgdboc internals + + The kgdboc driver is actually a very thin driver that relies on the + underlying low level to the hardware driver having "polling hooks" + which the to which the tty driver is attached. In the initial + implementation of kgdboc it the serial_core was changed to expose a + low level uart hook for doing polled mode reading and writing of a + single character while in an atomic context. When kgdb makes an I/O + request to the debugger, kgdboc invokes a call back in the serial + core which in turn uses the call back in the uart driver. It is + certainly possible to extend kgdboc to work with non-uart based + consoles in the future. + + + When using kgdboc with a uart, the uart driver must implement two callbacks in the struct uart_ops. Example from drivers/8250.c: +#ifdef CONFIG_CONSOLE_POLL + .poll_get_char = serial8250_get_poll_char, + .poll_put_char = serial8250_put_poll_char, +#endif + + Any implementation specifics around creating a polling driver use the + #ifdef CONFIG_CONSOLE_POLL, as shown above. + Keep in mind that polling hooks have to be implemented in such a way + that they can be called from an atomic context and have to restore + the state of the uart chip on return such that the system can return + to normal when the debugger detaches.

There -is a strong penalty if this method is used as loading the binary-only -module "taints" the kernel, and no kernel developer will help diagnose -any kernel problems. - -Development ------------ - -This driver has been developed using -a clean-room technique that is described at -http://bcm-specs.sipsolutions.net/ReverseEngineeringProcess. For legal -reasons, none of the clean-room crew works on the on the Linux driver, -and none of the Linux developers sees anything but the specifications, -which are the ultimate product of the reverse-engineering group. - -Software --------- - -Since the release of the 2.6.17 kernel, the bcm43xx driver has been -distributed with the kernel source, and is prebuilt in most, if not -all, distributions. There is, however, additional software that is -required. The firmware used by the chip is the intellectual property -of Broadcom and they have not given the bcm43xx team redistribution -rights to this firmware. Since we cannot legally redistribute -the firmware we cannot include it with the driver. Furthermore, it -cannot be placed in the downloadable archives of any distributing -organization; therefore, the user is responsible for obtaining the -firmware and placing it in the appropriate location so that the driver -can find it when initializing. - -To help with this process, the bcm43xx developers provide a separate -program named bcm43xx-fwcutter to "cut" the firmware out of a -Windows or OS X driver and write the extracted files to the proper -location. This program is usually provided with the distribution; -however, it may be downloaded from - -http://developer.berlios.de/project/showfiles.php?group_id=4547 - -The firmware is available in two versions. V3 firmware is used with -the in-kernel bcm43xx driver that uses a software MAC layer called -SoftMAC, and will have a microcode revision of 0x127 or smaller. The -V4 firmware is used by an out-of-kernel driver employing a variation of -the Devicescape MAC layer known as d80211. Once bcm43xx-d80211 reaches -a satisfactory level of development, it will replace bcm43xx-softmac -in the kernel as it is much more flexible and powerful. - -A source for the latest V3 firmware is - -http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o - -Once this file is downloaded, the command -'bcm43xx-fwcutter -w ' -will extract the microcode and write it to directory -. The correct directory will depend on your distribution; -however, most use '/lib/firmware'. Once this step is completed, -the bcm3xx driver should load when the system is booted. To see -any messages relating to the driver, issue the command 'dmesg | -grep bcm43xx' from a terminal window. If there are any problems, -please send that output to Bcm43xx-dev@lists.berlios.de. - -Although the driver has been in-kernel since 2.6.17, the earliest -version is quite limited in its capability. Patches that include -all features of later versions are available for the stable kernel -versions from 2.6.18. These will be needed if you use a BCM4318, -or a PCI Express version (BCM4311 and BCM4312). In addition, if you -have an early BCM4306 and more than 1 GB RAM, your kernel will need -to be patched. These patches, which are being updated regularly, -are available at ftp://lwfinger.dynalias.org/patches. Look for -combined_2.6.YY.patch. Of course you will need kernel source downloaded -from kernel.org, or the source from your distribution. - -If you build your own kernel, please enable CONFIG_BCM43XX_DEBUG -and CONFIG_IEEE80211_SOFTMAC_DEBUG. The log information provided is -essential for solving any problems. diff --git a/Documentation/networking/wan-router.txt b/Documentation/networking/wan-router.txt deleted file mode 100644 index bc2ab419a74aff2f60f147860cc66ff9713ef60f..0000000000000000000000000000000000000000 --- a/Documentation/networking/wan-router.txt +++ /dev/null @@ -1,621 +0,0 @@ ------------------------------------------------------------------------------- -Linux WAN Router Utilities Package ------------------------------------------------------------------------------- -Version 2.2.1 -Mar 28, 2001 -Author: Nenad Corbic -Copyright (c) 1995-2001 Sangoma Technologies Inc. ------------------------------------------------------------------------------- - -INTRODUCTION - -Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs) -and/or stand-alone hosts over vast distances with data transfer rates -significantly higher than those achievable with commonly used dial-up -connections. - -Usually an external device called `WAN router' sitting on your local network -or connected to your machine's serial port provides physical connection to -WAN. Although router's job may be as simple as taking your local network -traffic, converting it to WAN format and piping it through the WAN link, these -devices are notoriously expensive, with prices as much as 2 - 5 times higher -then the price of a typical PC box. - -Alternatively, considering robustness and multitasking capabilities of Linux, -an internal router can be built (most routers use some sort of stripped down -Unix-like operating system anyway). With a number of relatively inexpensive WAN -interface cards available on the market, a perfectly usable router can be -built for less than half a price of an external router. Yet a Linux box -acting as a router can still be used for other purposes, such as fire-walling, -running FTP, WWW or DNS server, etc. - -This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux -operating system and provides generic hardware-independent services for such -drivers. Why can existing Linux network device interface not be used for -this purpose? Well, it can. However, there are a few key differences between -a typical network interface (e.g. Ethernet) and a WAN link. - -Many WAN protocols, such as X.25 and frame relay, allow for multiple logical -connections (known as `virtual circuits' in X.25 terminology) over a single -physical link. Each such virtual circuit may (and almost always does) lead -to a different geographical location and, therefore, different network. As a -result, it is the virtual circuit, not the physical link, that represents a -route and, therefore, a network interface in Linux terms. - -To further complicate things, virtual circuits are usually volatile in nature -(excluding so called `permanent' virtual circuits or PVCs). With almost no -time required to set up and tear down a virtual circuit, it is highly desirable -to implement on-demand connections in order to minimize network charges. So -unlike a typical network driver, the WAN driver must be able to handle multiple -network interfaces and cope as multiple virtual circuits come into existence -and go away dynamically. - -Last, but not least, WAN configuration is much more complex than that of say -Ethernet and may well amount to several dozens of parameters. Some of them -are "link-wide" while others are virtual circuit-specific. The same holds -true for WAN statistics which is by far more extensive and extremely useful -when troubleshooting WAN connections. Extending the ifconfig utility to suit -these needs may be possible, but does not seem quite reasonable. Therefore, a -WAN configuration utility and corresponding application programmer's interface -is needed for this purpose. - -Most of these problems are taken care of by this module. Its goal is to -provide a user with more-or-less standard look and feel for all WAN devices and -assist a WAN device driver writer by providing common services, such as: - - o User-level interface via /proc file system - o Centralized configuration - o Device management (setup, shutdown, etc.) - o Network interface management (dynamic creation/destruction) - o Protocol encapsulation/decapsulation - -To ba able to use the Linux WAN Router you will also need a WAN Tools package -available from - - ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz - -where vX.Y.Z represent the wanpipe version number. - -For technical questions and/or comments please e-mail to ncorbic@sangoma.com. -For general inquiries please contact Sangoma Technologies Inc. by - - Hotline: 1-800-388-2475 (USA and Canada, toll free) - Phone: (905) 474-1990 ext: 106 - Fax: (905) 474-9223 - E-mail: dm@sangoma.com (David Mandelstam) - WWW: http://www.sangoma.com - - -INSTALLATION - -Please read the WanpipeForLinux.pdf manual on how to -install the WANPIPE tools and drivers properly. - - -After installing wanpipe package: /usr/local/wanrouter/doc. -On the ftp.sangoma.com : /linux/current_wanpipe/doc - - -COPYRIGHT AND LICENSING INFORMATION - -This program is free software; you can redistribute it and/or modify it under -the terms of the GNU General Public License as published by the Free Software -Foundation; either version 2, or (at your option) any later version. - -This program is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS -FOR A PARTICULAR PURPOSE.

Success of the WANPIPE -together with the next major release of Linux kernel in summer 1996 commanded -adequate changes to the WANPIPE code to take full advantage of new Linux -features. - -Instead of continuing developing proprietary interface tied to Sangoma WAN -cards, we decided to separate all hardware-independent code into a separate -module and defined two levels of interfaces - one for user-level applications -and another for kernel-level WAN drivers. WANPIPE is now implemented as a -WAN driver compliant with the WAN Link Driver interface. Also a general -purpose WAN configuration utility and a set of shell scripts was developed to -support WAN router at the user level. - -Many useful ideas concerning hardware-independent interface implementation -were given by Mike McLagan and his implementation -of the Frame Relay router and drivers for Sangoma cards (dlci/sdla). - -With the new implementation of the APIs being incorporated into the WANPIPE, -a special thank goes to Alan Cox in providing insight into BSD sockets. - -Special thanks to all the WANPIPE users who performed field-testing, reported -bugs and made valuable comments and suggestions that help us to improve this -product. - - - -NEW IN THIS RELEASE - - o Updated the WANCFG utility - Calls the pppconfig to configure the PPPD - for async connections. - - o Added the PPPCONFIG utility - Used to configure the PPPD daemon for the - WANPIPE Async PPP and standard serial port. - The wancfg calls the pppconfig to configure - the pppd. - - o Fixed the PCI autodetect feature. - The SLOT 0 was used as an autodetect option - however, some high end PC's slot numbers start - from 0. - - o This release has been tested with the new backupd - daemon release. - - -PRODUCT COMPONENTS AND RELATED FILES - -/etc: (or user defined) - wanpipe1.conf default router configuration file -

In particular, + PCI and I/O devices have been reinitialized and are + in a clean, consistent state. +-- As the dump is performed, the dumped memory becomes + immediately available to the system for normal use. +-- After the dump is completed, no further reboots are + required; the system will be fully usable, and running + in it's normal, production mode on it normal kernel. + +The above can only be accomplished by coordination with, +and assistance from the hypervisor. The procedure is +as follows: + +-- When a system crashes, the hypervisor will save + the low 256MB of RAM to a previously registered + save region. It will also save system state, system + registers, and hardware PTE's. + +-- After the low 256MB area has been saved, the + hypervisor will reset PCI and other hardware state. + It will *not* clear RAM. It will then launch the + bootloader, as normal. + +-- The freshly booted kernel will notice that there + is a new node (ibm,dump-kernel) in the device tree, + indicating that there is crash data available from + a previous boot. It will boot into only 256MB of RAM, + reserving the rest of system memory. + +-- Userspace tools will parse /sys/kernel/release_region + and read /proc/vmcore to obtain the contents of memory, + which holds the previous crashed kernel. The userspace + tools may copy this info to disk, or network, nas, san, + iscsi, etc. as desired. + + For Example: the values in /sys/kernel/release-region + would look something like this (address-range pairs). + CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: / + DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A + +-- As the userspace tools complete saving a portion of + dump, they echo an offset and size to + /sys/kernel/release_region to release the reserved + memory back to general use. + + An example of this is: + "echo 0x40000000 0x10000000 > /sys/kernel/release_region" + which will release 256MB at the 1GB boundary. + +Please note that the hypervisor-assisted dump feature +is only available on Power6-based systems with recent +firmware versions. + +Implementation details: +---------------------- + +During boot, a check is made to see if firmware supports +this feature on this particular machine. If it does, then +we check to see if a active dump is waiting for us. If yes +then everything but 256 MB of RAM is reserved during early +boot. This area is released once we collect a dump from user +land scripts that are run. If there is dump data, then +the /sys/kernel/release_region file is created, and +the reserved memory is held. + +If there is no waiting dump data, then only the highest +256MB of the ram is reserved as a scratch area. This area +is *not* released: this region will be kept permanently +reserved, so that it can act as a receptacle for a copy +of the low 256MB in the case a crash does occur. See, +however, "open issues" below, as to whether +such a reserved region is really needed. + +Currently the dump will be copied from /proc/vmcore to a +a new file upon user intervention. The starting address +to be read and the range for each data point in provided +in /sys/kernel/release_region. + +The tools to examine the dump will be same as the ones +used for kdump. + +General notes: +-------------- +Security: please note that there are potential security issues +with any sort of dump mechanism. In particular, plaintext +(unencrypted) data, and possibly passwords, may be present in +the dump data. Userspace tools must take adequate precautions to +preserve security. + +Open issues/ToDo: +------------ + o The various code paths that tell the hypervisor that a crash + occurred, vs. it simply being a normal reboot, should be + reviewed, and possibly clarified/fixed. + + o Instead of using /sys/kernel, should there be a /sys/dump + instead? There is a dump_subsys being created by the s390 code, + perhaps the pseries code should use a similar layout as well. + + o Is reserving a 256MB region really required? The goal of + reserving a 256MB scratch area is to make sure that no + important crash data is clobbered when the hypervisor + save low mem to the scratch area.

If you +want to assign bandwidth to another group, reduce the root group's bandwidth +and assign some or all of the difference to another group. + +Realtime group scheduling means you have to assign a portion of total CPU +bandwidth to the group before it will accept realtime tasks. Therefore you will +not be able to run realtime tasks as any user other than root until you have +done that, even if the user has the rights to run processes with realtime +priority! + + +2.3 Basis for grouping tasks +---------------------------- + +There are two compile-time settings for allocating CPU bandwidth. These are +configured using the "Basis for grouping tasks" multiple choice menu under +General setup > Group CPU Scheduler: + +a. CONFIG_USER_SCHED (aka "Basis for grouping tasks" = "user id") + +This lets you use the virtual files under +"/sys/kernel/uids//cpu_rt_runtime_us" to control he CPU time reserved for +each user . + +The other option is: + +.o CONFIG_CGROUP_SCHED (aka "Basis for grouping tasks" = "Control groups") + +This uses the /cgroup virtual file system and "/cgroup//cpu.rt_runtime_us" +to control the CPU time reserved for each control group instead. + +For more information on working with control groups, you should read +Documentation/cgroups.txt as well. + +Group settings are checked against the following limits in order to keep the configuration +schedulable: \Sum_{i} runtime_{i} / global_period <= global_runtime / global_period -in order to keep the configuration schedulable. +For now, this can be simplified to just the following (but see Future plans): + + \Sum_{i} runtime_{i} <= global_runtime + + +3. Future plans +=============== + +There is work in progress to make the scheduling period for each group +("/sys/kernel/uids//cpu_rt_period_us" or +"/cgroup//cpu.rt_period_us" respectively) configurable as well. + +The constraint on the period is that a subgroup must have a smaller or +equal period to its parent. But realistically its not very useful _yet_ +as its prone to starvation without deadline scheduling. + +Consider two sibling groups A and B; both have 50% bandwidth, but A's +period is twice the length of B's. + +* group A: period=100000us, runtime=10000us + - this runs for 0.01s once every 0.1s + +* group B: period= 50000us, runtime=10000us + - this runs for 0.01s twice every 0.1s (or once every 0.05 sec). + +This means that currently a while (1) loop in A will run for the full period of +B and can starve B's tasks (assuming they are of lower priority) for a whole +period. + +The next project will be SCHED_EDF (Earliest Deadline First scheduling) to bring +full deadline scheduling to the linux kernel. Deadline scheduling the above +groups and treating end of the period as a deadline will ensure that they both +get their allocated time. + +Implementing SCHED_EDF might take a while to complete. Priority Inheritance is +the biggest challenge as the current linux PI infrastructure is geared towards +the limited static priority levels 0-139.

Board Compatibility - -This device driver was forked from the driver for the DECchip "Tulip", -Digital's single-chip ethernet controllers for PCI. It supports Xircom's -almost-Tulip-compatible CBE-100 CardBus adapters. - -II. Board-specific settings - -PCI bus devices are configured by the system at boot time, so no jumpers -need to be set on the board. The system BIOS preferably should assign the -PCI INTA signal to an otherwise unused system IRQ line. - -III. Driver operation - -IIIa. Ring buffers - -The Xircom can use either ring buffers or lists of Tx and Rx descriptors. -This driver uses statically allocated rings of Rx and Tx descriptors, set at -compile time by RX/TX_RING_SIZE. This version of the driver allocates skbuffs -for the Rx ring buffers at open() time and passes the skb->data field to the -Xircom as receive data buffers. When an incoming frame is less than -RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is -copied to the new skbuff. When the incoming frame is larger, the skbuff is -passed directly up the protocol stack and replaced by a newly allocated -skbuff. - -The RX_COPYBREAK value is chosen to trade-off the memory wasted by -using a full-sized skbuff for small frames vs. the copying costs of larger -frames. For small frames the copying cost is negligible (esp. considering -that we are pre-loading the cache with immediately useful header -information). For large frames the copying cost is non-trivial, and the -larger copy might flush the cache of useful data. A subtle aspect of this -choice is that the Xircom only receives into longword aligned buffers, thus -the IP header at offset 14 isn't longword aligned for further processing. -Copied frames are put into the new skbuff at an offset of "+2", thus copying -has the beneficial effect of aligning the IP header and preloading the -cache. - -IIIC. Synchronization -The driver runs as two independent, single-threaded flows of control. One -is the send-packet routine, which enforces single-threaded use by the -dev->tbusy flag. The other thread is the interrupt handler, which is single -threaded by the hardware and other software. - -The send packet thread has partial control over the Tx ring and 'dev->tbusy' -flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next -queue slot is empty, it clears the tbusy flag when finished otherwise it sets -the 'tp->tx_full' flag. - -The interrupt handler has exclusive control over the Rx ring and records stats -from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so -we can't avoid the interrupt overhead by having the Tx routine reap the Tx -stats.) After reaping the stats, it marks the queue entry as empty by setting -the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the -tx_full and tbusy flags. - -IV. Notes - -IVb.

- /* - * sock_lock(): Lock a port/socket pair. lock_sock() can - * not be used here, since the same lock must protect ports - * with non-socket interfaces. - * See net.c for description of locking policy. + * Revised TIPC socket locking policy: + * + * Most socket operations take the standard socket lock when they start + * and hold it until they finish (or until they need to sleep). Acquiring + * this lock grants the owner exclusive access to the fields of the socket + * data structures, with the exception of the backlog queue. A few socket + * operations can be done without taking the socket lock because they only + * read socket information that never changes during the life of the socket. + * + * Socket operations may acquire the lock for the associated TIPC port if they + * need to perform an operation on the port. If any routine needs to acquire + * both the socket lock and the port lock it must take the socket lock first + * to avoid the risk of deadlock. + * + * The dispatcher handling incoming messages cannot grab the socket lock in + * the standard fashion, since invoked it runs at the BH level and cannot block. + * Instead, it checks to see if the socket lock is currently owned by someone, + * and either handles the message itself or adds it to the socket's backlog + * queue; in the latter case the queued message is processed once the process + * owning the socket lock releases it. + * + * NOTE: Releasing the socket lock while an operation is sleeping overcomes + * the problem of a blocked socket operation preventing any other operations + * from occurring. However, applications must be careful if they have + * multiple threads trying to send (or receive) on the same socket, as these + * operations might interfere with each other. For example, doing a connect + * and a receive at the same time might allow the receive to consume the + * ACK message meant for the connect. While additional work could be done + * to try and overcome this, it doesn't seem to be worthwhile at the present. + * + * NOTE: Releasing the socket lock while an operation is sleeping also ensures + * that another operation that must be performed in a non-blocking manner is + * not delayed for very long because the lock has already been taken. + * + * NOTE: This code assumes that certain fields of a port/socket pair are + * constant over its lifetime; such fields can be examined without taking + * the socket lock and/or port lock, and do not need to be re-read even + * after resuming processing after waiting.
