+switch the frequency very quickly. There are a number of sysfs file
+accessible parameters:
+
+sampling_rate: measured in uS (10^-6 seconds), this is how often you
+want the kernel to look at the CPU usage and to make decisions on
+what to do about the frequency. Typically this is set to values of
+around '10000' or more.
+
+show_sampling_rate_(min|max): the minimum and maximum sampling rates
+available that you may set 'sampling_rate' to.
+
+up_threshold: defines what the average CPU usaged between the samplings
+of 'sampling_rate' needs to be for the kernel to make a decision on
+whether it should increase the frequency. For example when it is set
+to its default value of '80' it means that between the checking
+intervals the CPU needs to be on average more than 80% in use to then
+decide that the CPU frequency needs to be increased.
+
+sampling_down_factor: this parameter controls the rate that the CPU
+makes a decision on when to decrease the frequency. When set to its
+default value of '5' it means that at 1/5 the sampling_rate the kernel
+makes a decision to lower the frequency. Five "lower rate" decisions
+have to be made in a row before the CPU frequency is actually lower.
+If set to '1' then the frequency decreases as quickly as it increases,
+if set to '2' it decreases at half the rate of the increase.
+
+ignore_nice_load: this parameter takes a value of '0' or '1', when set
+to '0' (its default) then all processes are counted towards towards the
+'cpu utilisation' value. When set to '1' then processes that are
+run with a 'nice' value will not count (and thus be ignored) in the
+overal usage calculation. This is useful if you are running a CPU
+intensive calculation on your laptop that you do not care how long it
+takes to complete as you can 'nice' it and prevent it from taking part
+in the deciding process of whether to increase your CPU frequency.
+2.5 Conservative
+----------------
+
+The CPUfreq governor "conservative", much like the "ondemand"
+governor, sets the CPU depending on the current usage. It differs in
+behaviour in that it gracefully increases and decreases the CPU speed
+rather than jumping to max speed the moment there is any load on the
+CPU. This behaviour more suitable in a battery powered environment.
+The governor is tweaked in the same manner as the "ondemand" governor
+through sysfs with the addition of:
+
+freq_step: this describes what percentage steps the cpu freq should be
+increased and decreased smoothly by. By default the cpu frequency will
+increase in 5% chunks of your maximum cpu frequency. You can change this
+value to anywhere between 0 and 100 where '0' will effectively lock your
+CPU at a speed regardless of its load whilst '100' will, in theory, make
+it behave identically to the "ondemand" governor.
+
+down_threshold: same as the 'up_threshold' found for the "ondemand"
+governor but for the opposite direction. For example when set to its
+default value of '20' it means that if the CPU usage needs to be below
+20% between samples to have the frequency decreased.

+The Gianfar Ethernet Driver
+Sysfs File description
+
+Author: Andy Fleming
+Updated: 2005-07-28
+
+SYSFS
+
+Several of the features of the gianfar driver are controlled
+through sysfs files. These are:
+
+bd_stash:
+To stash RX Buffer Descriptors in the L2, echo 'on' or '1' to
+bd_stash, echo 'off' or '0' to disable
+
+rx_stash_len:
+To stash the first n bytes of the packet in L2, echo the number
+of bytes to buf_stash_len. echo 0 to disable.
+
+WARNING: You could really screw these up if you set them too low or high!
+fifo_threshold:
+To change the number of bytes the controller needs in the
+fifo before it starts transmission, echo the number of bytes to
+fifo_thresh. Range should be 0-511.
+
+fifo_starve:
+When the FIFO has less than this many bytes during a transmit, it
+enters starve mode, and increases the priority of TX memory
+transactions. To change, echo the number of bytes to
+fifo_starve. Range should be 0-511.
+
+fifo_starve_off:
+Once in starve mode, the FIFO remains there until it has this
+many bytes. To change, echo the number of bytes to
+fifo_starve_off. Range should be 0-511.
+
+CHECKSUM OFFLOADING
+
+The eTSEC controller (first included in parts from late 2005 like
+the 8548) has the ability to perform TCP, UDP, and IP checksums
+in hardware. The Linux kernel only offloads the TCP and UDP
+checksums (and always performs the pseudo header checksums), so
+the driver only supports checksumming for TCP/IP and UDP/IP
+packets. Use ethtool to enable or disable this feature for RX
+and TX.
+
+VLAN
+
+In order to use VLAN, please consult Linux documentation on
+configuring VLANs. The gianfar driver supports hardware insertion and
+extraction of VLAN headers, but not filtering. Filtering will be
+done by the kernel.
+
+MULTICASTING
+
+The gianfar driver supports using the group hash table on the
+TSEC (and the extended hash table on the eTSEC) for multicast
+filtering. On the eTSEC, the exact-match MAC registers are used
+before the hash tables. See Linux documentation on how to join
+multicast groups.
+
+PADDING
+
+The gianfar driver supports padding received frames with 2 bytes
+to align the IP header to a 16-byte boundary, when supported by
+hardware.
+
+ETHTOOL
+
+The gianfar driver supports the use of ethtool for many
+configuration options. You must run ethtool only on currently
+open interfaces. See ethtool documentation for details.

+ Hopefully we'll be getting the build restriction zapped much sooner,

+ If the driver supports the suspend/resume
+ fully, that is, the device can be
+ properly resumed to the status at the suspend is called,
+ you can set SNDRV_PCM_INFO_RESUME flag
+ to pcm info field. Usually, this is possible when the
+ registers of ths chip can be safely saved and restored to the
+ RAM. If this is set, the trigger callback is called with
+ SNDRV_PCM_TRIGGER_RESUME after resume
+ callback is finished.
+
+
+
+ Even if the driver doesn't support PM fully but only the
+ partial suspend/resume is possible, it's still worthy to
+ implement suspend/resume callbacks. In such a case, applications
+ would reset the status by calling
+ snd_pcm_prepare() and restart the stream
+ appropriately. Hence, you can define suspend/resume callbacks
+ below but don't set SNDRV_PCM_INFO_RESUME
+ info flag to the PCM.

+ Note that the trigger with SUSPEND can be always called when

+ (Thus, in theory,

- * - Added support for lacp_rate module param.
- *
- * 2003/05/01 - Shmulik Hen
- * - Based on discussion on mailing list, changed locking scheme
- * to use lock/unlock or lock_bh/unlock_bh appropriately instead
- * of lock_irqsave/unlock_irqrestore. The new scheme helps exposing
- * hidden bugs and solves system hangs that occurred due to the fact
- * that holding lock_irqsave doesn't prevent softirqs from running.
- * This also increases total throughput since interrupts are not
- * blocked on each transmitted packets or monitor timeout.
- *
- * 2003/05/01 - Shmulik Hen
- * - Renamed bond_3ad_link_status_changed() to
- * bond_3ad_handle_link_change() for compatibility with TLB.

- * 2003/05/20 - Amir Noam
- * - Fix long fail over time when releasing last slave of an active
- * aggregator - send LACPDU on unbind of slave to tell partner this
- * port is no longer aggregatable.
- *
- * 2003/06/25 - Tsippy Mendelson

*
- * v0.1 - first working version.
- * v0.2 - changed stats to be calculated by summing slaves stats.
- *
- * Changes:
- * Arnaldo Carvalho de Melo
- * - fix leaks on failure at bond_init
- *
- * 2000/09/30 - Willy Tarreau
- * - added trivial code to release a slave device.
- * - fixed security bug (CAP_NET_ADMIN not checked)
- * - implemented MII link monitoring to disable dead links :
- * All MII capable slaves are checked every milliseconds
- * (100 ms seems good). This value can be changed by passing it to
- * insmod. A value of zero disables the monitoring (default).
- * - fixed an infinite loop in bond_xmit_roundrobin() when there's no
- * good slave.
- * - made the code hopefully SMP safe
- *
- * 2000/10/03 - Willy Tarreau
- * - optimized slave lists based on relevant suggestions from Thomas Davis
- * - implemented active-backup method to obtain HA with two switches:
- * stay as long as possible on the same active interface, while we
- * also monitor the backup one (MII link status) because we want to know
- * if we are able to switch at any time. ( pass "mode=1" to insmod )
- * - lots of stress testings because we need it to be more robust than the
- * wires ! :->
- *
- * 2000/10/09 - Willy Tarreau
- * - added up and down delays after link state change.
- * - optimized the slaves chaining so that when we run forward, we never
- * repass through the bond itself, but we can find it by searching
- * backwards. Renders the deletion more difficult, but accelerates the
- * scan.
- * - smarter enslaving and releasing.
- * - finer and more robust SMP locking
- *
- * 2000/10/17 - Willy Tarreau
- * - fixed two potential SMP race conditions
- *
- * 2000/10/18 - Willy Tarreau
- * - small fixes to the monitoring FSM in case of zero delays
- * 2000/11/01 - Willy Tarreau
- * - fixed first slave not automatically used in trunk mode.
- * 2000/11/10 : spelling of "EtherChannel" corrected.
- * 2000/11/13 : fixed a race condition in case of concurrent accesses to ioctl().
- * 2000/12/16 : fixed improper usage of rtnl_exlock_nowait().
- *
- * 2001/1/3 - Chad N. Tindel
- * - The bonding driver now simulates MII status monitoring, just like
- * a normal network device. It will show that the link is down iff
- * every slave in the bond shows that their links are down. If at least
- * one slave is up, the bond's MII status will appear as up.
- *
- * 2001/2/7 - Chad N. Tindel
- * - Applications can now query the bond from user space to get
- * information which may be useful. They do this by calling
- * the BOND_INFO_QUERY ioctl. Once the app knows how many slaves
- * are in the bond, it can call the BOND_SLAVE_INFO_QUERY ioctl to
- * get slave specific information (# link failures, etc). See
- * for more details. The structs of interest
- * are ifbond and ifslave.
- *
- * 2001/4/5 - Chad N. Tindel
- * - Ported to 2.4 Kernel
- *
- * 2001/5/2 - Jeffrey E. Mast
- * - When a device is detached from a bond, the slave device is no longer
- * left thinking that is has a master.
- *
- * 2001/5/16 - Jeffrey E. Mast
- * - memset did not appropriately initialized the bond rw_locks. Used
- * rwlock_init to initialize to unlocked state to prevent deadlock when
- * first attempting a lock
- * - Called SET_MODULE_OWNER for bond device
- *
- * 2001/5/17 - Tim Anderson
- * - 2 paths for releasing for slave release; 1 through ioctl
- * and 2) through close. Both paths need to release the same way.
- * - the free slave in bond release is changing slave status before
- * the free. The netdev_set_master() is intended to change slave state
- * so it should not be done as part of the release process.
- * - Simple rule for slave state at release: only the active in A/B and
- * only one in the trunked case.
- *
- * 2001/6/01 - Tim Anderson
- * - Now call dev_close when releasing a slave so it doesn't screw up
- * out routing table.

- *
- * 2001/8/05 - Janice Girouard
- * - correct problem where refcnt of slave is not incremented in bond_ioctl

- *
- * 2001/9/13 - Takao Indoh
- * - Add the BOND_CHANGE_ACTIVE ioctl implementation
- *
- * 2001/9/14 - Mark Huth

- * but only for an up link.
- *
- * 2001/9/20 - Chad N. Tindel
- * - Add the device field to bonding_t. Previously the net_device

- *
- * 2002/1/2 - Chad N. Tindel
- * - Restore original slave flags at release time.
- *
- * 2002/02/18 - Erik Habbinga
- * - bond_release(): calling kfree on our_slave after call to
- * bond_restore_slave_flags, not before
- * - bond_enslave(): saving slave flags into original_flags before
- * call to netdev_set_master, so the IFF_SLAVE flag doesn't end
- * up in original_flags
- *
- * 2002/04/05 - Mark Smith and
- * Steve Mead
- * - Port Gleb Natapov's multicast support patchs from 2.4.12
- * to 2.4.18 adding support for multicast.
- *
- * 2002/06/10 - Tony Cureington
- * - corrected uninitialized pointer (ifr.ifr_data) in bond_check_dev_link;

- * ETHTOOL to determine the link status
- * - fixed bad ifr_data pointer assignments in bond_ioctl
- * - corrected mode 1 being reported as active-backup in bond_get_info;

- * to "s" (a single ptr)
- *
- * 2002/08/30 - Jay Vosburgh
- * - Removed acquisition of xmit_lock in set_multicast_list; caused

- *
- * 2002/9/30 - Jay Vosburgh
- * - make sure the ip target matches the arp_target before saving the
- * hw address.
- *
- * 2002/9/30 - Dan Eisner
- * - make sure my_ip is set before taking down the link, since
- * not all switches respond if the source ip is not set.
- *
- * 2002/10/8 - Janice Girouard
- * - read in the local ip address when enslaving a device
- * - add primary support
- * - make sure 2*arp_interval has passed when a new device
- * is brought on-line before taking it down.
- *
- * 2002/09/11 - Philippe De Muyter
- * - Added bond_xmit_broadcast logic.
- * - Added bond_mode() support function.
- *
- * 2002/10/26 - Laurent Deniel
- * - allow to register multicast addresses only on active slave
- * (useful in active-backup mode)
- * - add multicast module parameter
- * - fix deletion of multicast groups after unloading module
- *
- * 2002/11/06 - Kameshwara Rayaprolu
- * - Changes to prevent panic from closing the device twice; if we close
- * the device in bond_release, we must set the original_flags to down
- * so it won't be closed again by the network layer.
- *
- * 2002/11/07 - Tony Cureington
- * - Fix arp_target_hw_addr memory leak
- * - Created activebackup_arp_monitor function to handle arp monitoring
- * in active backup mode - the bond_arp_monitor had several problems...
- * such as allowing slaves to tx arps sequentially without any delay
- * for a response
- * - Renamed bond_arp_monitor to loadbalance_arp_monitor and re-wrote
- * this function to just handle arp monitoring in load-balancing mode;
- * it is a lot more compact now
- * - Changes to ensure one and only one slave transmits in active-backup
- * mode
- * - Robustesize parameters; warn users about bad combinations of
- * parameters; also if miimon is specified and a network driver does
- * not support MII or ETHTOOL, inform the user of this
- * - Changes to support link_failure_count when in arp monitoring mode
- * - Fix up/down delay reported in /proc
- * - Added version; log version; make version available from "modinfo -d"
- * - Fixed problem in bond_check_dev_link - if the first IOCTL (SIOCGMIIPH)
- * failed, the ETHTOOL ioctl never got a chance
- *
- * 2002/11/16 - Laurent Deniel
- * - fix multicast handling in activebackup_arp_monitor
- * - remove one unnecessary and confusing curr_active_slave == slave test
- * in activebackup_arp_monitor
- *
- * 2002/11/17 - Laurent Deniel
- * - fix bond_slave_info_query when slave_id = num_slaves
- *
- * 2002/11/19 - Janice Girouard
- * - correct ifr_data reference. Update ifr_data reference
- * to mii_ioctl_data struct values to avoid confusion.
- *
- * 2002/11/22 - Bert Barbe
- * - Add support for multiple arp_ip_target
- *
- * 2002/12/13 - Jay Vosburgh
- * - Changed to allow text strings for mode and multicast, e.g.,
- * insmod bonding mode=active-backup. The numbers still work.
- * One change: an invalid choice will cause module load failure,
- * rather than the previous behavior of just picking one.
- * - Minor cleanups; got rid of dup ctype stuff, atoi function
- *
- * 2003/02/07 - Jay Vosburgh
- * - Added use_carrier module parameter that causes miimon to
- * use netif_carrier_ok() test instead of MII/ETHTOOL ioctls.
- * - Minor cleanups; consolidated ioctl calls to one function.
- *
- * 2003/02/07 - Tony Cureington
- * - Fix bond_mii_monitor() logic error that could result in
- * bonding round-robin mode ignoring links after failover/recovery
- *
- * 2003/03/17 - Jay Vosburgh
- * - kmalloc fix (GFP_KERNEL to GFP_ATOMIC) reported by
- * Shmulik dot Hen at intel.com.
- * - Based on discussion on mailing list, changed use of
- * update_slave_cnt(), created wrapper functions for adding/removing
- * slaves, changed bond_xmit_xor() to check slave_cnt instead of
- * checking slave and slave->dev (which only worked by accident).
- * - Misc code cleanup: get arp_send() prototype from header file,
- * add max_bonds to bonding.txt.
- *
- * 2003/03/18 - Tsippy Mendelson and
- * Shmulik Hen
- * - Make sure only bond_attach_slave() and bond_detach_slave() can
- * manipulate the slave list, including slave_cnt, even when in
- * bond_release_all().
- * - Fixed hang in bond_release() with traffic running:
- * netdev_set_master() must not be called from within the bond lock.
- *
- * 2003/03/18 - Tsippy Mendelson and
- * Shmulik Hen
- * - Fixed hang in bond_enslave() with traffic running:
- * netdev_set_master() must not be called from within the bond lock.
- *
- * 2003/03/18 - Amir Noam
- * - Added support for getting slave's speed and duplex via ethtool.
- * Needed for 802.3ad and other future modes.
- *
- * 2003/03/18 - Tsippy Mendelson and
- * Shmulik Hen
- * - Enable support of modes that need to use the unique mac address of
- * each slave.
- * * bond_enslave(): Moved setting the slave's mac address, and
- * openning it, from the application to the driver. This breaks
- * backward comaptibility with old versions of ifenslave that open
- * the slave before enalsving it !!!.
- * * bond_release(): The driver also takes care of closing the slave
- * and restoring its original mac address.
- * - Removed the code that restores all base driver's flags.
- * Flags are automatically restored once all undo stages are done
- * properly.
- * - Block possibility of enslaving before the master is up. This
- * prevents putting the system in an unstable state.
- *
- * 2003/03/18 - Amir Noam ,
- * Tsippy Mendelson and
- * Shmulik Hen
- * - Added support for IEEE 802.3ad Dynamic link aggregation mode.
- *
- * 2003/05/01 - Amir Noam
- * - Added ABI version control to restore compatibility between
- * new/old ifenslave and new/old bonding.
- *
- * 2003/05/01 - Shmulik Hen
- * - Fixed bug in bond_release_all(): save old value of curr_active_slave
- * before setting it to NULL.
- * - Changed driver versioning scheme to include version number instead
- * of release date (that is already in another field). There are 3
- * fields X.Y.Z where:
- * X - Major version - big behavior changes
- * Y - Minor version - addition of features
- * Z - Extra version - minor changes and bug fixes
- * The current version is 1.0.0 as a base line.
- *
- * 2003/05/01 - Tsippy Mendelson and
- * Amir Noam
- * - Added support for lacp_rate module param.
- * - Code beautification and style changes (mainly in comments).
- * new version - 1.0.1
- *
- * 2003/05/01 - Shmulik Hen
- * - Based on discussion on mailing list, changed locking scheme
- * to use lock/unlock or lock_bh/unlock_bh appropriately instead
- * of lock_irqsave/unlock_irqrestore. The new scheme helps exposing
- * hidden bugs and solves system hangs that occurred due to the fact
- * that holding lock_irqsave doesn't prevent softirqs from running.
- * This also increases total throughput since interrupts are not
- * blocked on each transmitted packets or monitor timeout.
- * new version - 2.0.0
- *
- * 2003/05/01 - Shmulik Hen
- * - Added support for Transmit load balancing mode.
- * - Concentrate all assignments of curr_active_slave to a single point
- * so specific modes can take actions when the primary adapter is
- * changed.
- * - Take the updelay parameter into consideration during bond_enslave
- * since some adapters loose their link during setting the device.
- * - Renamed bond_3ad_link_status_changed() to
- * bond_3ad_handle_link_change() for compatibility with TLB.
- * new version - 2.1.0
- *
- * 2003/05/01 - Tsippy Mendelson
- * - Added support for Adaptive load balancing mode which is
- * equivalent to Transmit load balancing + Receive load balancing.
- * new version - 2.2.0
- *
- * 2003/05/15 - Jay Vosburgh
- * - Applied fix to activebackup_arp_monitor posted to bonding-devel
- * by Tony Cureington . Fixes ARP
- * monitor endless failover bug. Version to 2.2.10
- *
- * 2003/05/20 - Amir Noam
- * - Fixed bug in ABI version control - Don't commit to a specific
- * ABI version if receiving unsupported ioctl commands.
- *
- * 2003/05/22 - Jay Vosburgh
- * - Fix ifenslave -c causing bond to loose existing routes;
- * added bond_set_mac_address() that doesn't require the
- * bond to be down.
- * - In conjunction with fix for ifenslave -c, in
- * bond_change_active(), changing to the already active slave
- * is no longer an error (it successfully does nothing).
- *
- * 2003/06/30 - Amir Noam
- * - Fixed bond_change_active() for ALB/TLB modes.
- * Version to 2.2.14.
- *
- * 2003/07/29 - Amir Noam
- * - Fixed ARP monitoring bug.
- * Version to 2.2.15.
- *
- * 2003/07/31 - Willy Tarreau
- * - Fixed kernel panic when using ARP monitoring without
- * setting bond's IP address.
- * Version to 2.2.16.
- *
- * 2003/08/06 - Amir Noam
- * - Back port from 2.6: use alloc_netdev(); fix /proc handling;
- * made stats a part of bond struct so no need to allocate
- * and free it separately; use standard list operations instead
- * of pre-allocated array of bonds.
- * Version to 2.3.0.
- *
- * 2003/08/07 - Jay Vosburgh ,
- * Amir Noam and
- * Shmulik Hen
- * - Propagating master's settings: Distinguish between modes that
- * use a primary slave from those that don't, and propagate settings
- * accordingly; Consolidate change_active opeartions and add
- * reselect_active and find_best opeartions; Decouple promiscuous
- * handling from the multicast mode setting; Add support for changing
- * HW address and MTU with proper unwind; Consolidate procfs code,
- * add CHANGENAME handler; Enhance netdev notification handling.
- * Version to 2.4.0.
- *
- * 2003/09/15 - Stephen Hemminger ,
- * Amir Noam
- * - Convert /proc to seq_file interface.
- * Change /proc/net/bondX/info to /proc/net/bonding/bondX.
- * Set version to 2.4.1.
- *
- * 2003/11/20 - Amir Noam
- * - Fix /proc creation/destruction.
- *
- * 2003/12/01 - Shmulik Hen
- * - Massive cleanup - Set version to 2.5.0
- * Code changes:
- * o Consolidate format of prints and debug prints.
- * o Remove bonding_t/slave_t typedefs and consolidate all casts.
- * o Remove dead code and unnecessary checks.
- * o Consolidate starting/stopping timers.
- * o Consolidate handling of primary module param throughout the code.
- * o Removed multicast module param support - all settings are done
- * according to mode.
- * o Slave list iteration - bond is no longer part of the list,
- * added cyclic list iteration macros.
- * o Consolidate error handling in all xmit functions.
- * Style changes:
- * o Consolidate function naming and declarations.
- * o Consolidate function params and local variables names.
- * o Consolidate return values.
- * o Consolidate curly braces.
- * o Consolidate conditionals format.
- * o Change struct member names and types.
- * o Chomp trailing spaces, remove empty lines, fix indentations.
- * o Re-organize code according to context.
- *
- * 2003/12/30 - Amir Noam
- * - Fixed: Cannot remove and re-enslave the original active slave.
- * - Fixed: Releasing the original active slave causes mac address
- * duplication.
- * - Add support for slaves that use ethtool_ops.
- * Set version to 2.5.3.
- *
- * 2004/01/05 - Amir Noam
- * - Save bonding parameters per bond instead of using the global values.
- * Set version to 2.5.4.
- *
- * 2004/01/14 - Shmulik Hen

- * Set version to 2.6.0.
- * 2004/10/29 - Mitch Williams
- * - Fixed bug when unloading module while using 802.3ad. If
- * spinlock debugging is turned on, this causes a stack dump.
- * Solution is to move call to dev_remove_pack outside of the
- * spinlock.
- * Set version to 2.6.1.
- * 2005/06/05 - Jay Vosburgh
- * - Support for generating gratuitous ARPs in active-backup mode.
- * Includes support for VLAN tagging all bonding-generated ARPs
- * as needed. Set version to 2.6.2.
- * 2005/06/08 - Jason Gabler
- * - alternate hashing policy support for mode 2
- * * Added kernel parameter "xmit_hash_policy" to allow the selection
- * of different hashing policies for mode 2. The original mode 2
- * policy is the default, now found in xmit_hash_policy_layer2().
- * * Added xmit_hash_policy_layer34()
- * - Modified by Jay Vosburgh to also support mode 4.
- * Set version to 2.6.3.
- * 2005/09/26 - Jay Vosburgh
- * - Removed backwards compatibility for old ifenslaves. Version 2.6.4.
