+I/O Barriers
+============
+Tejun Heo <htejun@gmail.com>, July 22 2005
+
+I/O barrier requests are used to guarantee ordering around the barrier
+requests. Unless you're crazy enough to use disk drives for
+implementing synchronization constructs (wow, sounds interesting...),
+the ordering is meaningful only for write requests for things like
+journal checkpoints. All requests queued before a barrier request
+must be finished (made it to the physical medium) before the barrier
+request is started, and all requests queued after the barrier request
+must be started only after the barrier request is finished (again,
+made it to the physical medium).
+
+In other words, I/O barrier requests have the following two properties.
+
+1. Request ordering
+
+Requests cannot pass the barrier request. Preceding requests are
+processed before the barrier and following requests after.
+
+Depending on what features a drive supports, this can be done in one
+of the following three ways.
+
+i. For devices which have queue depth greater than 1 (TCQ devices) and
+support ordered tags, block layer can just issue the barrier as an
+ordered request and the lower level driver, controller and drive
+itself are responsible for making sure that the ordering contraint is
+met. Most modern SCSI controllers/drives should support this.
+
+NOTE: SCSI ordered tag isn't currently used due to limitation in the
+ SCSI midlayer, see the following random notes section.
+
+ii. For devices which have queue depth greater than 1 but don't
+support ordered tags, block layer ensures that the requests preceding
+a barrier request finishes before issuing the barrier request. Also,
+it defers requests following the barrier until the barrier request is
+finished. Older SCSI controllers/drives and SATA drives fall in this
+category.
+
+iii. Devices which have queue depth of 1. This is a degenerate case
+of ii. Just keeping issue order suffices. Ancient SCSI
+controllers/drives and IDE drives are in this category.
+
+2. Forced flushing to physcial medium
+
+Again, if you're not gonna do synchronization with disk drives (dang,
+it sounds even more appealing now!), the reason you use I/O barriers
+is mainly to protect filesystem integrity when power failure or some
+other events abruptly stop the drive from operating and possibly make
+the drive lose data in its cache. So, I/O barriers need to guarantee
+that requests actually get written to non-volatile medium in order.
+
+There are four cases,
+
+i. No write-back cache. Keeping requests ordered is enough.
+
+ii. Write-back cache but no flush operation. There's no way to
+gurantee physical-medium commit order. This kind of devices can't to
+I/O barriers.
+
+iii. Write-back cache and flush operation but no FUA (forced unit
+access). We need two cache flushes - before and after the barrier
+request.
+
+iv. Write-back cache, flush operation and FUA. We still need one
+flush to make sure requests preceding a barrier are written to medium,
+but post-barrier flush can be avoided by using FUA write on the
+barrier itself.
+
+
+How to support barrier requests in drivers
+------------------------------------------
+
+All barrier handling is done inside block layer proper. All low level
+drivers have to are implementing its prepare_flush_fn and using one
+the following two functions to indicate what barrier type it supports
+and how to prepare flush requests. Note that the term 'ordered' is
+used to indicate the whole sequence of performing barrier requests
+including draining and flushing.
+
+typedef void (prepare_flush_fn)(request_queue_t *q, struct request *rq);
+
+int blk_queue_ordered(request_queue_t *q, unsigned ordered,
+ prepare_flush_fn *prepare_flush_fn,
+ unsigned gfp_mask);
+
+int blk_queue_ordered_locked(request_queue_t *q, unsigned ordered,
+ prepare_flush_fn *prepare_flush_fn,
+ unsigned gfp_mask);
+
+The only difference between the two functions is whether or not the
+caller is holding q->queue_lock on entry. The latter expects the
+caller is holding the lock.
+
+@q : the queue in question
+@ordered : the ordered mode the driver/device supports
+@prepare_flush_fn : this function should prepare @rq such that it
+ flushes cache to physical medium when executed
+@gfp_mask : gfp_mask used when allocating data structures
+ for ordered processing
+
+For example, SCSI disk driver's prepare_flush_fn looks like the
+following.
+
+static void sd_prepare_flush(request_queue_t *q, struct request *rq)
+{
+ memset(rq->cmd, 0, sizeof(rq->cmd));
+ rq->flags |= REQ_BLOCK_PC;
+ rq->timeout = SD_TIMEOUT;
+ rq->cmd[0] = SYNCHRONIZE_CACHE;
+}
+
+The following seven ordered modes are supported. The following table
+shows which mode should be used depending on what features a
+device/driver supports. In the leftmost column of table,
+QUEUE_ORDERED_ prefix is omitted from the mode names to save space.
+
+The table is followed by description of each mode. Note that in the
+descriptions of QUEUE_ORDERED_DRAIN*, '=>' is used whereas '->' is
+used for QUEUE_ORDERED_TAG* descriptions. '=>' indicates that the
+preceding step must be complete before proceeding to the next step.
+'->' indicates that the next step can start as soon as the previous
+step is issued.
+
+ write-back cache ordered tag flush FUA
+-----------------------------------------------------------------------
+NONE yes/no N/A no N/A
+DRAIN no no N/A N/A
+DRAIN_FLUSH yes no yes no
+DRAIN_FUA yes no yes yes
+TAG no yes N/A N/A
+TAG_FLUSH yes yes yes no
+TAG_FUA yes yes yes yes
+
+
+QUEUE_ORDERED_NONE
+ I/O barriers are not needed and/or supported.
+
+ Sequence: N/A
+
+QUEUE_ORDERED_DRAIN
+ Requests are ordered by draining the request queue and cache
+ flushing isn't needed.
+
+ Sequence: drain => barrier
+
+QUEUE_ORDERED_DRAIN_FLUSH
+ Requests are ordered by draining the request queue and both
+ pre-barrier and post-barrier cache flushings are needed.
+
+ Sequence: drain => preflush => barrier => postflush
+
+QUEUE_ORDERED_DRAIN_FUA
+ Requests are ordered by draining the request queue and
+ pre-barrier cache flushing is needed. By using FUA on barrier
+ request, post-barrier flushing can be skipped.
+
+ Sequence: drain => preflush => barrier
+
+QUEUE_ORDERED_TAG
+ Requests are ordered by ordered tag and cache flushing isn't
+ needed.
+
+ Sequence: barrier
+
+QUEUE_ORDERED_TAG_FLUSH
+ Requests are ordered by ordered tag and both pre-barrier and
+ post-barrier cache flushings are needed.
+
+ Sequence: preflush -> barrier -> postflush
+
+QUEUE_ORDERED_TAG_FUA
+ Requests are ordered by ordered tag and pre-barrier cache
+ flushing is needed. By using FUA on barrier request,
+ post-barrier flushing can be skipped.
+
+ Sequence: preflush -> barrier
+
+
+Random notes/caveats
+--------------------
+
+* SCSI layer currently can't use TAG ordering even if the drive,
+controller and driver support it. The problem is that SCSI midlayer
+request dispatch function is not atomic. It releases queue lock and
+switch to SCSI host lock during issue and it's possible and likely to
+happen in time that requests change their relative positions. Once
+this problem is solved, TAG ordering can be enabled.
+
+* Currently, no matter which ordered mode is used, there can be only
+one barrier request in progress. All I/O barriers are held off by
+block layer until the previous I/O barrier is complete. This doesn't
+make any difference for DRAIN ordered devices, but, for TAG ordered
+devices with very high command latency, passing multiple I/O barriers
+to low level *might* be helpful if they are very frequent. Well, this
+certainly is a non-issue. I'm writing this just to make clear that no
+two I/O barrier is ever passed to low-level driver.
+
+* Completion order. Requests in ordered sequence are issued in order
+but not required to finish in order. Barrier implementation can
+handle out-of-order completion of ordered sequence. IOW, the requests
+MUST be processed in order but the hardware/software completion paths
+are allowed to reorder completion notifications - eg. current SCSI
+midlayer doesn't preserve completion order during error handling.
+
+* Requeueing order. Low-level drivers are free to requeue any request
+after they removed it from the request queue with
+blkdev_dequeue_request(). As barrier sequence should be kept in order
+when requeued, generic elevator code takes care of putting requests in
+order around barrier. See blk_ordered_req_seq() and
+ELEVATOR_INSERT_REQUEUE handling in __elv_add_request() for details.
+
+Note that block drivers must not requeue preceding requests while
+completing latter requests in an ordered sequence. Currently, no
+error checking is done against this.
+
+* Error handling. Currently, block layer will report error to upper
+layer if any of requests in an ordered sequence fails. Unfortunately,
+this doesn't seem to be enough. Look at the following request flow.
+QUEUE_ORDERED_TAG_FLUSH is in use.
+
+ [0] [1] [2] [3] [pre] [barrier] [post] < [4] [5] [6] ... >
+ still in elevator
+
+Let's say request [2], [3] are write requests to update file system
+metadata (journal or whatever) and [barrier] is used to mark that
+those updates are valid. Consider the following sequence.
+
+ i. Requests [0] ~ [post] leaves the request queue and enters
+ low-level driver.
+ ii. After a while, unfortunately, something goes wrong and the
+ drive fails [2]. Note that any of [0], [1] and [3] could have
+ completed by this time, but [pre] couldn't have been finished
+ as the drive must process it in order and it failed before
+ processing that command.
+ iii. Error handling kicks in and determines that the error is
+ unrecoverable and fails [2], and resumes operation.
+ iv. [pre] [barrier] [post] gets processed.
+ v. *BOOM* power fails
+
+The problem here is that the barrier request is *supposed* to indicate
+that filesystem update requests [2] and [3] made it safely to the
+physical medium and, if the machine crashes after the barrier is
+written, filesystem recovery code can depend on that. Sadly, that
+isn't true in this case anymore. IOW, the success of a I/O barrier
+should also be dependent on success of some of the preceding requests,
+where only upper layer (filesystem) knows what 'some' is.
+
+This can be solved by implementing a way to tell the block layer which
+requests affect the success of the following barrier request and
+making lower lever drivers to resume operation on error only after
+block layer tells it to do so.
+
+As the probability of this happening is very low and the drive should
+be faulty, implementing the fix is probably an overkill. But, still,
+it's there.
+
+* In previous drafts of barrier implementation, there was fallback
+mechanism such that, if FUA or ordered TAG fails, less fancy ordered
+mode can be selected and the failed barrier request is retried
+automatically. The rationale for this feature was that as FUA is
+pretty new in ATA world and ordered tag was never used widely, there
+could be devices which report to support those features but choke when
+actually given such requests.
+
+ This was removed for two reasons 1. it's an overkill 2. it's
+impossible to implement properly when TAG ordering is used as low
+level drivers resume after an error automatically. If it's ever
+needed adding it back and modifying low level drivers accordingly
+shouldn't be difficult.

+EDAC - Error Detection And Correction
+
+Written by Doug Thompson <norsk5@xmission.com>
+7 Dec 2005
+
+
+EDAC was written by:
+ Thayne Harbaugh,
+ modified by Dave Peterson, Doug Thompson, et al,
+ from the bluesmoke.sourceforge.net project.
+
+
+============================================================================
+EDAC PURPOSE
+
+The 'edac' kernel module goal is to detect and report errors that occur
+within the computer system. In the initial release, memory Correctable Errors
+(CE) and Uncorrectable Errors (UE) are the primary errors being harvested.
+
+Detecting CE events, then harvesting those events and reporting them,
+CAN be a predictor of future UE events. With CE events, the system can
+continue to operate, but with less safety. Preventive maintainence and
+proactive part replacement of memory DIMMs exhibiting CEs can reduce
+the likelihood of the dreaded UE events and system 'panics'.
+
+
+In addition, PCI Bus Parity and SERR Errors are scanned for on PCI devices
+in order to determine if errors are occurring on data transfers.
+The presence of PCI Parity errors must be examined with a grain of salt.
+There are several addin adapters that do NOT follow the PCI specification
+with regards to Parity generation and reporting. The specification says
+the vendor should tie the parity status bits to 0 if they do not intend
+to generate parity. Some vendors do not do this, and thus the parity bit
+can "float" giving false positives.
+
+The PCI Parity EDAC device has the ability to "skip" known flakey
+cards during the parity scan. These are set by the parity "blacklist"
+interface in the sysfs for PCI Parity. (See the PCI section in the sysfs
+section below.) There is also a parity "whitelist" which is used as
+an explicit list of devices to scan, while the blacklist is a list
+of devices to skip.
+
+EDAC will have future error detectors that will be added or integrated
+into EDAC in the following list:
+
+ MCE Machine Check Exception
+ MCA Machine Check Architecture
+ NMI NMI notification of ECC errors
+ MSRs Machine Specific Register error cases
+ and other mechanisms.
+
+These errors are usually bus errors, ECC errors, thermal throttling
+and the like.
+
+
+============================================================================
+EDAC VERSIONING
+
+EDAC is composed of a "core" module (edac_mc.ko) and several Memory
+Controller (MC) driver modules. On a given system, the CORE
+is loaded and one MC driver will be loaded. Both the CORE and
+the MC driver have individual versions that reflect current release
+level of their respective modules. Thus, to "report" on what version
+a system is running, one must report both the CORE's and the
+MC driver's versions.
+
+
+LOADING
+
+If 'edac' was statically linked with the kernel then no loading is
+necessary. If 'edac' was built as modules then simply modprobe the
+'edac' pieces that you need. You should be able to modprobe
+hardware-specific modules and have the dependencies load the necessary core
+modules.
+
+Example:
+
+$> modprobe amd76x_edac
+
+loads both the amd76x_edac.ko memory controller module and the edac_mc.ko
+core module.
+
+
+============================================================================
+EDAC sysfs INTERFACE
+
+EDAC presents a 'sysfs' interface for control, reporting and attribute
+reporting purposes.
+
+EDAC lives in the /sys/devices/system/edac directory. Within this directory
+there currently reside 2 'edac' components:
+
+ mc memory controller(s) system
+ pci PCI status system
+
+
+============================================================================
+Memory Controller (mc) Model
+
+First a background on the memory controller's model abstracted in EDAC.
+Each mc device controls a set of DIMM memory modules. These modules are
+layed out in a Chip-Select Row (csrowX) and Channel table (chX). There can
+be multiple csrows and two channels.
+
+Memory controllers allow for several csrows, with 8 csrows being a typical value.
+Yet, the actual number of csrows depends on the electrical "loading"
+of a given motherboard, memory controller and DIMM characteristics.
+
+Dual channels allows for 128 bit data transfers to the CPU from memory.
+
+
+ Channel 0 Channel 1
+ ===================================
+ csrow0 | DIMM_A0 | DIMM_B0 |
+ csrow1 | DIMM_A0 | DIMM_B0 |
+ ===================================
+
+ ===================================
+ csrow2 | DIMM_A1 | DIMM_B1 |
+ csrow3 | DIMM_A1 | DIMM_B1 |
+ ===================================
+
+In the above example table there are 4 physical slots on the motherboard
+for memory DIMMs:
+
+ DIMM_A0
+ DIMM_B0
+ DIMM_A1
+ DIMM_B1
+
+Labels for these slots are usually silk screened on the motherboard. Slots
+labeled 'A' are channel 0 in this example. Slots labled 'B'
+are channel 1. Notice that there are two csrows possible on a
+physical DIMM. These csrows are allocated their csrow assignment
+based on the slot into which the memory DIMM is placed. Thus, when 1 DIMM
+is placed in each Channel, the csrows cross both DIMMs.
+
+Memory DIMMs come single or dual "ranked". A rank is a populated csrow.
+Thus, 2 single ranked DIMMs, placed in slots DIMM_A0 and DIMM_B0 above
+will have 1 csrow, csrow0. csrow1 will be empty. On the other hand,
+when 2 dual ranked DIMMs are similiaryly placed, then both csrow0 and
+csrow1 will be populated. The pattern repeats itself for csrow2 and
+csrow3.
+
+The representation of the above is reflected in the directory tree
+in EDAC's sysfs interface. Starting in directory
+/sys/devices/system/edac/mc each memory controller will be represented
+by its own 'mcX' directory, where 'X" is the index of the MC.
+
+
+ ..../edac/mc/
+ |
+ |->mc0
+ |->mc1
+ |->mc2
+ ....
+
+Under each 'mcX' directory each 'csrowX' is again represented by a
+'csrowX', where 'X" is the csrow index:
+
+
+ .../mc/mc0/
+ |
+ |->csrow0
+ |->csrow2
+ |->csrow3
+ ....
+
+Notice that there is no csrow1, which indicates that csrow0 is
+composed of a single ranked DIMMs. This should also apply in both
+Channels, in order to have dual-channel mode be operational. Since
+both csrow2 and csrow3 are populated, this indicates a dual ranked
+set of DIMMs for channels 0 and 1.
+
+
+Within each of the 'mc','mcX' and 'csrowX' directories are several
+EDAC control and attribute files.
+
+
+============================================================================
+DIRECTORY 'mc'
+
+In directory 'mc' are EDAC system overall control and attribute files:
+
+
+Panic on UE control file:
+
+ 'panic_on_ue'
+
+ An uncorrectable error will cause a machine panic. This is usually
+ desirable. It is a bad idea to continue when an uncorrectable error
+ occurs - it is indeterminate what was uncorrected and the operating
+ system context might be so mangled that continuing will lead to further
+ corruption. If the kernel has MCE configured, then EDAC will never
+ notice the UE.
+
+ LOAD TIME: module/kernel parameter: panic_on_ue=[0|1]
+
+ RUN TIME: echo "1" >/sys/devices/system/edac/mc/panic_on_ue
+
+
+Log UE control file:
+
+ 'log_ue'
+
+ Generate kernel messages describing uncorrectable errors. These errors
+ are reported through the system message log system. UE statistics
+ will be accumulated even when UE logging is disabled.
+
+ LOAD TIME: module/kernel parameter: log_ue=[0|1]
+
+ RUN TIME: echo "1" >/sys/devices/system/edac/mc/log_ue
+
+
+Log CE control file:
+
+ 'log_ce'
+
+ Generate kernel messages describing correctable errors. These
+ errors are reported through the system message log system.
+ CE statistics will be accumulated even when CE logging is disabled.
+
+ LOAD TIME: module/kernel parameter: log_ce=[0|1]
+
+ RUN TIME: echo "1" >/sys/devices/system/edac/mc/log_ce
+
+
+Polling period control file:
+
+ 'poll_msec'
+
+ The time period, in milliseconds, for polling for error information.
+ Too small a value wastes resources. Too large a value might delay
+ necessary handling of errors and might loose valuable information for
+ locating the error. 1000 milliseconds (once each second) is about
+ right for most uses.
+
+ LOAD TIME: module/kernel parameter: poll_msec=[0|1]
+
+ RUN TIME: echo "1000" >/sys/devices/system/edac/mc/poll_msec
+
+
+Module Version read-only attribute file:
+
+ 'mc_version'
+
+ The EDAC CORE modules's version and compile date are shown here to
+ indicate what EDAC is running.
+
+
+
+============================================================================
+'mcX' DIRECTORIES
+
+
+In 'mcX' directories are EDAC control and attribute files for
+this 'X" instance of the memory controllers:
+
+
+Counter reset control file:
+
+ 'reset_counters'
+

+channel 1 "DIMM_B1": amd76x_edac
+
+
+The structure of the message is:
+ the memory controller (MC0)
+ Error type (CE)
+ memory page (0x283)
+ offset in the page (0xce0)
+ the byte granularity (grain 8)
+ or resolution of the error
+ the error syndrome (0xb741)
+ memory row (row 0)
+ memory channel (channel 1)
+ DIMM label, if set prior (DIMM B1
+ and then an optional, driver-specific message that may
+ have additional information.
+
+Both UEs and CEs with no info will lack all but memory controller,
+error type, a notice of "no info" and then an optional,
+driver-specific error message.

+
+============================================================================
+PCI Bus Parity Detection
+
+
+On Header Type 00 devices the primary status is looked at
+for any parity error regardless of whether Parity is enabled on the
+device. (The spec indicates parity is generated in some cases).
+On Header Type 01 bridges, the secondary status register is also
+looked at to see if parity ocurred on the bus on the other side of
+the bridge.
+
+
+SYSFS CONFIGURATION
+
+Under /sys/devices/system/edac/pci are control and attribute files as follows:
+
+
+Enable/Disable PCI Parity checking control file:
+
+ 'check_pci_parity'
+
+
+ This control file enables or disables the PCI Bus Parity scanning
+ operation. Writing a 1 to this file enables the scanning. Writing
+ a 0 to this file disables the scanning.
+
+ Enable:
+ echo "1" >/sys/devices/system/edac/pci/check_pci_parity
+
+ Disable:
+ echo "0" >/sys/devices/system/edac/pci/check_pci_parity
+
+
+
+Panic on PCI PARITY Error:
+
+ 'panic_on_pci_parity'
+
+
+ This control files enables or disables panic'ing when a parity
+ error has been detected.
+
+
+ module/kernel parameter: panic_on_pci_parity=[0|1]
+
+ Enable:
+ echo "1" >/sys/devices/system/edac/pci/panic_on_pci_parity
+
+ Disable:
+ echo "0" >/sys/devices/system/edac/pci/panic_on_pci_parity
+
+
+Parity Count:
+
+ 'pci_parity_count'
+
+ This attribute file will display the number of parity errors that
+ have been detected.
+
+
+
+PCI Device Whitelist:
+
+ 'pci_parity_whitelist'
+
+ This control file allows for an explicit list of PCI devices to be
+ scanned for parity errors. Only devices found on this list will
+ be examined. The list is a line of hexadecimel VENDOR and DEVICE
+ ID tuples:
+
+ 1022:7450,1434:16a6
+
+ One or more can be inserted, seperated by a comma.
+
+ To write the above list doing the following as one command line:
+
+ echo "1022:7450,1434:16a6"
+ > /sys/devices/system/edac/pci/pci_parity_whitelist
+
+
+
+ To display what the whitelist is, simply 'cat' the same file.
+
+
+PCI Device Blacklist:
+
+ 'pci_parity_blacklist'
+
+ This control file allows for a list of PCI devices to be
+ skipped for scanning.
+ The list is a line of hexadecimel VENDOR and DEVICE ID tuples:

+
+ To display what the whitelist current contatins,
+ simply 'cat' the same file.
+
+=======================================================================
+
+PCI Vendor and Devices IDs can be obtained with the lspci command. Using
+the -n option lspci will display the vendor and device IDs. The system
+adminstrator will have to determine which devices should be scanned or
+skipped.
+
+
+
+The two lists (white and black) are prioritized. blacklist is the lower
+priority and will NOT be utilized when a whitelist has been set.
+Turn OFF a whitelist by an empty echo command:
+
+ echo > /sys/devices/system/edac/pci/pci_parity_whitelist
+
+and any previous blacklist will be utililzed.

+FUSE sets up the following hierarchy in sysfs:
+
+ /sys/fs/fuse/connections/N/

+For each connection the following attributes are defined:

+
+Only a privileged user may read or write these attributes.
+
+Aborting a filesystem connection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is possible to get into certain situations where the filesystem is
+not responding. Reasons for this may be:
+
+ a) Broken userspace filesystem implementation
+
+ b) Network connection down

+ c) Accidental deadlock
+
+ d) Malicious deadlock

+ - Kill the filesystem daemon. Works in case of a) and b)
+
+ - Kill the filesystem daemon and all users of the filesystem. Works
+ in all cases except some malicious deadlocks
+
+ - Use forced umount (umount -f). Works in all cases but only if
+ filesystem is still attached (it hasn't been lazy unmounted)

+ - Abort filesystem through the sysfs interface. Most powerful

+ Linux is a clone of the operating system Unix, written from scratch by
+ Linus Torvalds with assistance from a loosely-knit team of hackers across
+ the Net. It aims towards POSIX and Single UNIX Specification compliance.
- It has all the features you would expect in a modern fully-fledged
- Unix, including true multitasking, virtual memory, shared libraries,
- demand loading, shared copy-on-write executables, proper memory
- management and TCP/IP networking.
+ It has all the features you would expect in a modern fully-fledged Unix,
+ including true multitasking, virtual memory, shared libraries, demand
+ loading, shared copy-on-write executables, proper memory management,
+ and multistack networking including IPv4 and IPv6.
It is distributed under the GNU General Public License - see the
accompanying COPYING file for more details.
ON WHAT HARDWARE DOES IT RUN?
- Linux was first developed for 386/486-based PCs. These days it also
- runs on ARMs, DEC Alphas, SUN Sparcs, M68000 machines (like Atari and
- Amiga), MIPS and PowerPC, and others.
+ Although originally developed first for 32-bit x86-based PCs (386 or higher),
+ today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and
+ UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH,
+ IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64, AXIS CRIS,
+ and Renesas M32R architectures.
+
+ Linux is easily portable to most general-purpose 32- or 64-bit architectures
+ as long as they have a paged memory management unit (PMMU) and a port of the
+ GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
+ also been ported to a number of architectures without a PMMU, although
+ functionality is then obviously somewhat limited.

+ * There are several things to be aware of that aren't at all obvious:
+ *
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!). In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices: The individual chip on a memory stick. These devices
+ * commonly output 4 and 8 bits each. Grouping several
+ * of these in parallel provides 64 bits which is common
+ * for a memory stick.
+ *
+ * Memory Stick: A printed circuit board that agregates multiple
+ * memory devices in parallel. This is the atomic
+ * memory component that is purchaseable by Joe consumer
+ * and loaded into a memory socket.
+ *
+ * Socket: A physical connector on the motherboard that accepts
+ * a single memory stick.
+ *
+ * Channel: Set of memory devices on a memory stick that must be
+ * grouped in parallel with one or more additional
+ * channels from other memory sticks. This parallel
+ * grouping of the output from multiple channels are
+ * necessary for the smallest granularity of memory access.
+ * Some memory controllers are capable of single channel -
+ * which means that memory sticks can be loaded
+ * individually. Other memory controllers are only
+ * capable of dual channel - which means that memory
+ * sticks must be loaded as pairs (see "socket set").
+ *
+ * Chip-select row: All of the memory devices that are selected together.
+ * for a single, minimum grain of memory access.
+ * This selects all of the parallel memory devices across
+ * all of the parallel channels. Common chip-select rows
+ * for single channel are 64 bits, for dual channel 128
+ * bits.
+ *
+ * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memmory.
+ * Motherboards commonly drive two chip-select pins to
+ * a memory stick. A single-ranked stick, will occupy
+ * only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick: A double-ranked stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently.
+ *
+ * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
+ * A double-sided stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently. "Double-sided"
+ * is irrespective of the memory devices being mounted
+ * on both sides of the memory stick.
+ *
+ * Socket set: All of the memory sticks that are required for for
+ * a single memory access or all of the memory sticks
+ * spanned by a chip-select row. A single socket set
+ * has two chip-select rows and if double-sided sticks
+ * are used these will occupy those chip-select rows.
+ *
+ * Bank: This term is avoided because it is unclear when
+ * needing to distinguish between chip-select rows and
+ * socket sets.
+ *
+ * Controller pages:
+ *
+ * Physical pages:
+ *
+ * Virtual pages:

/* Change Log
- * 6.0.58 4/20/05
- * o Accepted ethtool cleanup patch from Stephen Hemminger
- * 6.0.44+ 2/15/05
- * o applied Anton's patch to resolve tx hang in hardware
- * o Applied Andrew Mortons patch - e1000 stops working after resume
+ * 6.3.9 12/16/2005
+ * o incorporate fix for recycled skbs from IBM LTC
+ * 6.3.7 11/18/2005
+ * o Honor eeprom setting for enabling/disabling Wake On Lan
+ * 6.3.5 11/17/2005
+ * o Fix memory leak in rx ring handling for PCI Express adapters
+ * 6.3.4 11/8/05
+ * o Patch from Jesper Juhl to remove redundant NULL checks for kfree
+ * 6.3.2 9/20/05
+ * o Render logic that sets/resets DRV_LOAD as inline functions to
+ * avoid code replication. If f/w is AMT then set DRV_LOAD only when
+ * network interface is open.
+ * o Handle DRV_LOAD set/reset in cases where AMT uses VLANs.
+ * o Adjust PBA partioning for Jumbo frames using MTU size and not
+ * rx_buffer_len
+ * 6.3.1 9/19/05
+ * o Use adapter->tx_timeout_factor in Tx Hung Detect logic
+ (e1000_clean_tx_irq)
+ * o Support for 8086:10B5 device (Quad Port)
+ * 6.2.14 9/15/05
+ * o In AMT enabled configurations, set/reset DRV_LOAD bit on interface
+ * open/close
+ * 6.2.13 9/14/05
+ * o Invoke e1000_check_mng_mode only for 8257x controllers since it
+ * accesses the FWSM that is not supported in other controllers
+ * 6.2.12 9/9/05
+ * o Add support for device id E1000_DEV_ID_82546GB_QUAD_COPPER
+ * o set RCTL:SECRC only for controllers newer than 82543.
+ * o When the n/w interface comes down reset DRV_LOAD bit to notify f/w.
+ * This code was moved from e1000_remove to e1000_close
+ * 6.2.10 9/6/05
+ * o Fix error in updating RDT in el1000_alloc_rx_buffers[_ps] -- one off.
+ * o Enable fc by default on 82573 controllers (do not read eeprom)
+ * o Fix rx_errors statistic not to include missed_packet_count
+ * o Fix rx_dropped statistic not to include missed_packet_count
+ (Padraig Brady)
+ * 6.2.9 8/30/05
+ * o Remove call to update statistics from the controller ib e1000_get_stats
+ * 6.2.8 8/30/05
+ * o Improved algorithm for rx buffer allocation/rdt update
+ * o Flow control watermarks relative to rx PBA size
+ * o Simplified 'Tx Hung' detect logic
+ * 6.2.7 8/17/05
+ * o Report rx buffer allocation failures and tx timeout counts in stats
+ * 6.2.6 8/16/05
+ * o Implement workaround for controller erratum -- linear non-tso packet
+ * following a TSO gets written back prematurely
+ * 6.2.5 8/15/05
+ * o Set netdev->tx_queue_len based on link speed/duplex settings.
+ * o Fix net_stats.rx_fifo_errors <p@draigBrady.com>
+ * o Do not power off PHY if SoL/IDER session is active
+ * 6.2.4 8/10/05
+ * o Fix loopback test setup/cleanup for 82571/3 controllers
+ * o Fix parsing of outgoing packets (e1000_transfer_dhcp_info) to treat
+ * all packets as raw
+ * o Prevent operations that will cause the PHY to be reset if SoL/IDER
+ * sessions are active and log a message
+ * 6.2.2 7/21/05
+ * o used fixed size descriptors for all MTU sizes, reduces memory load
+ * 6.1.2 4/13/05
+ * o Fixed ethtool diagnostics
+ * o Enabled flow control to take default eeprom settings
+ * o Added stats_lock around e1000_read_phy_reg commands to avoid concurrent
+ * calls, one from mii_ioctl and other from within update_stats while
+ * processing MIIREG ioctl.
