So it appears to +be a good idea to always test if the memory is working correctly, +before looking for any other potential causes of any problems. + +U-Boot implements 3 different approaches to perform memory tests: + +1. The get_ram_size() function (see "common/memsize.c"). + + This function is supposed to be used in each and every U-Boot port + determine the presence and actual size of each of the potential + memory banks on this piece of hardware. The code is supposed to be + very fast, so running it for each reboot does not hurt. It is a + little known and generally underrated fact that this code will also + catch 99% of hardware related (i. e. reliably reproducible) memory + errors. It is strongly recommended to always use this function, in + each and every port of U-Boot. + +2. The "mtest" command. + + This is probably the best known memory test utility in U-Boot. + Unfortunately, it is also the most problematic, and the most + useless one. + + There are a number of serious problems with this command: + + - It is terribly slow. Running "mtest" on the whole system RAM + takes a _long_ time before there is any significance in the fact + that no errors have been found so far. + + - It is difficult to configure, and to use. And any errors here + will reliably crash or hang your system. "mtest" is dumb and has + no knowledge about memory ranges that may be in use for other + purposes, like exception code, U-Boot code and data, stack, + malloc arena, video buffer, log buffer, etc. If you let it, it + will happily "test" all such areas, which of course will cause + some problems. + + - It is not easy to configure and use, and a large number of + systems are seriously misconfigured. The original idea was to + test basically the whole system RAM, with only exempting the + areas used by U-Boot itself - on most systems these are the areas + used for the exception vectors (usually at the very lower end of + system memory) and for U-Boot (code, data, etc. - see above; + these are usually at the very upper end of system memory). But + experience has shown that a very large number of ports use + pretty much bogus settings of CONFIG_SYS_MEMTEST_START and + CONFIG_SYS_MEMTEST_END; this results in useless tests (because + the ranges is too small and/or badly located) or in critical + failures (system crashes). + + Because of these issues, the "mtest" command is considered depre- + cated. It should not be enabled in most normal ports of U-Boot, + especially not in production. If you really need a memory test, + then see 1. and 3. above resp. below. + +3. The most thorough memory test facility is available as part of the + POST (Power-On Self Test) sub-system, see "post/drivers/memory.c". + + If you really need to perform memory tests (for example, because + it is mandatory part of your requirement specification), then + enable this test which is generic and should work on all archi- + tectures. + +WARNING: + +It should pointed out that _all_ these memory tests have one +fundamental, unfixable design flaw: they are based on the assumption +that memory errors can be found by writing to and reading from memory. +Unfortunately, this is only true for the relatively harmless, usually +static errors like shorts between data or address lines, unconnected +pins, etc. All the really nasty errors which will first turn your +hair gray, only to make you tear it out later, are dynamical errors, +which usually happen not with simple read or write cycles on the bus, +but when performing back-to-back data transfers in burst mode. Such +accesses usually happen only for certain DMA operations, or for heavy +cache use (instruction fetching, cache flushing). So far I am not +aware of any freely available code that implements a generic, and +efficient, memory test like that. The best known test case to stress +a system like that is to boot Linux with root file system mounted over +NFS, and then build some larger software package natively (say, +compile a Linux kernel on the system) - this will cause enough context +switches, network traffic (and thus DMA transfers from the network +controller), varying RAM use, etc. to trigger any weak spots in this +area. + +Note: An attempt was made once to implement such a test to catch +memory problems on a specific board. The code is pretty much board +specific (for example, it includes setting specific GPIO signals to +provide triggers for an attached logic analyzer), but you can get an +idea how it works: see "examples/standalone/test_burst*". + +Note 2: Ironically enough, the "test_burst" did not catch any RAM +errors, not a single one ever. The problems this code was supposed +to catch did not happen when accessing the RAM, but when reading from +NOR flash. diff --git a/doc/README.scrapyard b/doc/README.scrapyard index e9ca96cba7..189b8839d5 100644 --- a/doc/README.scrapyard +++ b/doc/README.scrapyard @@ -90,3 +90,5 @@ MVS1 powerpc MPC823 306620b 2008-08-26 Andre Schwar adsvix ARM PXA27x 7610db1 2008-07-30 Adrian Filipi <adrian.filipi@eurotech.com> R5200 ColdFire - 48ead7a 2008-03-31 Zachary P.

In + * addition to providing an example of a genuinely useful composite + * function for a USB device, it also illustrates a technique of + * double-buffering for increased throughput. + * + * Function supports multiple logical units (LUNs). Backing storage + * for each LUN is provided by a regular file or a block device. + * Access for each LUN can be limited to read-only. Moreover, the + * function can indicate that LUN is removable and/or CD-ROM. (The + * later implies read-only access.) + * + * MSF is configured by specifying a fsg_config structure.

This + * should be filled for each LUN that + * function will include (ie. for "nluns" + * LUNs). Each element of the array has + * the following fields: + * ->filename The path to the backing file for the LUN. + * Required if LUN is not marked as + * removable. + * ->ro Flag specifying access to the LUN shall be + * read-only. This is implied if CD-ROM + * emulation is enabled as well as when + * it was impossible to open "filename" + * in R/W mode. + * ->removable Flag specifying that LUN shall be indicated as + * being removable. + * ->cdrom Flag specifying that LUN shall be reported as + * being a CD-ROM. + * + * lun_name_format A printf-like format for names of the LUN + * devices. This determines how the + * directory in sysfs will be named. + * Unless you are using several MSFs in + * a single gadget (as opposed to single + * MSF in many configurations) you may + * leave it as NULL (in which case + * "lun%d" will be used). In the format + * you can use "%d" to index LUNs for + * MSF's with more than one LUN. (Beware + * that there is only one integer given + * as an argument for the format and + * specifying invalid format may cause + * unspecified behaviour.) + * thread_name Name of the kernel thread process used by the + * MSF. You can safely set it to NULL + * (in which case default "file-storage" + * will be used). + * + * vendor_name + * product_name + * release Information used as a reply to INQUIRY + * request. To use default set to NULL, + * NULL, 0xffff respectively. The first + * field should be 8 and the second 16 + * characters or less. + * + * can_stall Set to permit function to halt bulk endpoints. + * Disabled on some USB devices known not + * to work correctly. You should set it + * to true. + * + * If "removable" is not set for a LUN then a backing file must be + * specified. If it is set, then NULL filename means the LUN's medium + * is not loaded (an empty string as "filename" in the fsg_config + * structure causes error). The CD-ROM emulation includes a single + * data track and no audio tracks; hence there need be only one + * backing file per LUN. Note also that the CD-ROM block length is + * set to 512 rather than the more common value 2048. + * + * + * MSF includes support for module parameters. If gadget using it + * decides to use it, the following module parameters will be + * available: + * + * file=filename[,filename...] + * Names of the files or block devices used for + * backing storage. + * ro=b[,b...] Default false, boolean for read-only access. + * removable=b[,b...] + * Default true, boolean for removable media. + * cdrom=b[,b...] Default false, boolean for whether to emulate + * a CD-ROM drive. + * luns=N Default N = number of filenames, number of + * LUNs to support. + * stall Default determined according to the type of + * USB device controller (usually true), + * boolean to permit the driver to halt + * bulk endpoints. + * + * The module parameters may be prefixed with some string. You need + * to consult gadget's documentation or source to verify whether it is + * using those module parameters and if it does what are the prefixes + * (look for FSG_MODULE_PARAMETERS() macro usage, what's inside it is + * the prefix). + * + * + * Requirements are modest; only a bulk-in and a bulk-out endpoint are + * needed. The memory requirement amounts to two 16K buffers, size + * configurable by a parameter. Support is included for both + * full-speed and high-speed operation. + * + * Note that the driver is slightly non-portable in that it assumes a + * single memory/DMA buffer will be useable for bulk-in, bulk-out, and + * interrupt-in endpoints. With most device controllers this isn't an + * issue, but there may be some with hardware restrictions that prevent + * a buffer from being used by more than one endpoint. + * + * + * The pathnames of the backing files and the ro settings are + * available in the attribute files "file" and "ro" in the lun<n> (or + * to be more precise in a directory which name comes from + * "lun_name_format" option!) subdirectory of the gadget's sysfs + * directory. If the "removable" option is set, writing to these + * files will simulate ejecting/loading the medium (writing an empty + * line means eject) and adjusting a write-enable tab. Changes to the + * ro setting are not allowed when the medium is loaded or if CD-ROM + * emulation is being used. + * + * When a LUN receive an "eject" SCSI request (Start/Stop Unit), + * if the LUN is removable, the backing file is released to simulate + * ejection. + * + * + * This function is heavily based on "File-backed Storage Gadget" by + * Alan Stern which in turn is heavily based on "Gadget Zero" by David + * Brownell. The driver's SCSI command interface was based on the + * "Information technology - Small Computer System Interface - 2" + * document from X3T9.2 Project 375D, Revision 10L, 7-SEP-93, + * available at <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>. + * The single exception is opcode 0x23 (READ FORMAT CAPACITIES), which + * was based on the "Universal Serial Bus Mass Storage Class UFI + * Command Specification" document, Revision 1.0, December 14, 1998, + * available at + * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>. + */ + + +/* + * Driver Design + * + * The MSF is fairly straightforward. There is a main kernel + * thread that handles most of the work. Interrupt routines field + * callbacks from the controller driver: bulk- and interrupt-request + * completion notifications, endpoint-0 events, and disconnect events. + * Completion events are passed to the main thread by wakeup calls. Many + * ep0 requests are handled at interrupt time, but SetInterface, + * SetConfiguration, and device reset requests are forwarded to the + * thread in the form of "exceptions" using SIGUSR1 signals (since they + * should interrupt any ongoing file I/O operations). + * + * The thread's main routine implements the standard command/data/status + * parts of a SCSI interaction. It and its subroutines are full of tests + * for pending signals/exceptions -- all this polling is necessary since + * the kernel has no setjmp/longjmp equivalents. (Maybe this is an + * indication that the driver really wants to be running in userspace.) + * An important point is that so long as the thread is alive it keeps an + * open reference to the backing file. This will prevent unmounting + * the backing file's underlying filesystem and could cause problems + * during system shutdown, for example. To prevent such problems, the + * thread catches INT, TERM, and KILL signals and converts them into + * an EXIT exception. + * + * In normal operation the main thread is started during the gadget's + * fsg_bind() callback and stopped during fsg_unbind(). But it can + * also exit when it receives a signal, and there's no point leaving + * the gadget running when the thread is dead. At of this moment, MSF + * provides no way to deregister the gadget when thread dies -- maybe + * a callback functions is needed. + * + * To provide maximum throughput, the driver uses a circular pipeline of + * buffer heads (struct fsg_buffhd). In principle the pipeline can be + * arbitrarily long; in practice the benefits don't justify having more + * than 2 stages (i.e., double buffering). But it helps to think of the + * pipeline as being a long one. Each buffer head contains a bulk-in and + * a bulk-out request pointer (since the buffer can be used for both + * output and input -- directions always are given from the host's + * point of view) as well as a pointer to the buffer and various state + * variables. + * + * Use of the pipeline follows a simple protocol. There is a variable + * (fsg->next_buffhd_to_fill) that points to the next buffer head to use. + * At any time that buffer head may still be in use from an earlier + * request, so each buffer head has a state variable indicating whether + * it is EMPTY, FULL, or BUSY. Typical use involves waiting for the + * buffer head to be EMPTY, filling the buffer either by file I/O or by + * USB I/O (during which the buffer head is BUSY), and marking the buffer + * head FULL when the I/O is complete. Then the buffer will be emptied + * (again possibly by USB I/O, during which it is marked BUSY) and + * finally marked EMPTY again (possibly by a completion routine). + * + * A module parameter tells the driver to avoid stalling the bulk + * endpoints wherever the transport specification allows. This is + * necessary for some UDCs like the SuperH, which cannot reliably clear a + * halt on a bulk endpoint. However, under certain circumstances the + * Bulk-only specification requires a stall. In such cases the driver + * will halt the endpoint and set a flag indicating that it should clear + * the halt in software during the next device reset. Hopefully this + * will permit everything to work correctly. Furthermore, although the + * specification allows the bulk-out endpoint to halt when the host sends + * too much data, implementing this would cause an unavoidable race. + * The driver will always use the "no-stall" approach for OUT transfers. + * + * One subtle point concerns sending status-stage responses for ep0 + * requests. Some of these requests, such as device reset, can involve + * interrupting an ongoing file I/O operation, which might take an + * arbitrarily long time. During that delay the host might give up on + * the original ep0 request and issue a new one. When that happens the + * driver should not notify the host about completion of the original + * request, as the host will no longer be waiting for it. So the driver + * assigns to each ep0 request a unique tag, and it keeps track of the + * tag value of the request associated with a long-running exception + * (device-reset, interface-change, or configuration-change).
