-What: old static regulatory information and ieee80211_regdom module parameter
-When: 2.6.29
+What: The ieee80211_regdom module parameter
+When: March 2010 / desktop catchup
+
+Why: This was inherited by the CONFIG_WIRELESS_OLD_REGULATORY code,
+ and currently serves as an option for users to define an
+ ISO / IEC 3166 alpha2 code for the country they are currently
+ present in. Although there are userspace API replacements for this
+ through nl80211 distributions haven't yet caught up with implementing
+ decent alternatives through standard GUIs. Although available as an
+ option through iw or wpa_supplicant its just a matter of time before
+ distributions pick up good GUI options for this. The ideal solution
+ would actually consist of intelligent designs which would do this for
+ the user automatically even when travelling through different countries.
+ Until then we leave this module parameter as a compromise.
+
+ When userspace improves with reasonable widely-available alternatives for
+ this we will no longer need this module parameter. This entry hopes that
+ by the super-futuristically looking date of "March 2010" we will have
+ such replacements widely available.
+
+Who: Luis R. Rodriguez
+
+---------------------------
+
+What: CONFIG_WIRELESS_OLD_REGULATORY - old static regulatory information
+When: March 2010 / desktop catchup
+
Why: The old regulatory infrastructure has been replaced with a new one
which does not require statically defined regulatory domains. We do
not want to keep static regulatory domains in the kernel due to the
the dynamic nature of regulatory law and localization. We kept around
the old static definitions for the regulatory domains of:
+
* US
* JP
* EU
+
and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was
- set. We also kept around the ieee80211_regdom module parameter in case
- some applications were relying on it. Changing regulatory domains
- can now be done instead by using nl80211, as is done with iw.

+This file describes the ixgbe Linux Base Driver for the 10 Gigabit PCI
+Express Intel(R) Network Connection. This driver includes support for
+Itanium(R)2-based systems.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your 10 Gigabit adapter. All hardware requirements listed apply
+to use with Linux.
+
+The following features are available in this kernel:
+ - Native VLANs
+ - Channel Bonding (teaming)
+ - SNMP
+ - Generic Receive Offload
+ - Data Center Bridging
+
+Channel Bonding documentation can be found in the Linux kernel source:
+/Documentation/networking/bonding.txt
+
+Ethtool, lspci, and ifconfig can be used to display device and driver
+specific information.
+
+
+Identifying Your Adapter
+========================
+
+This driver supports devices based on the 82598 controller and the 82599
+controller.

+ insmod /lib/modules//kernel/drivers/net/ixgbe/ixgbe.ko
+
+ With 2.6 based kernels also make sure that older ixgbe drivers are
+ removed from the kernel, before loading the new module:
+
+ rmmod ixgbe; modprobe ixgbe
+
+3. Assign an IP address to the interface by entering the following, where
+ x is the interface number:
+
+ ifconfig ethx
+
+4. Verify that the interface works. Enter the following, where
+ is the IP address for another machine on the same subnet as the interface
+ that is being tested:
+
+ ping
+
+
+Additional Configurations
+=========================
+
+ Viewing Link Messages
+ ---------------------
+ Link messages will not be displayed to the console if the distribution is
+ restricting system messages. In order to see network driver link messages on
+ your console, set dmesg to eight by entering the following:
+
+ dmesg -n 8
+
+ NOTE: This setting is not saved across reboots.
+
+
+ Jumbo Frames
+ ------------
+ The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
+ enabled by changing the MTU to a value larger than the default of 1500.
+ The maximum value for the MTU is 16110. Use the ifconfig command to
+ increase the MTU size. For example:
+
+ ifconfig ethx mtu 9000 up
+
+ The maximum MTU setting for Jumbo Frames is 16110. This value coincides
+ with the maximum Jumbo Frames size of 16128.
+
+ Generic Receive Offload, aka GRO
+ --------------------------------
+ The driver supports the in-kernel software implementation of GRO. GRO has
+ shown that by coalescing Rx traffic into larger chunks of data, CPU
+ utilization can be significantly reduced when under large Rx load. GRO is an
+ evolution of the previously-used LRO interface. GRO is able to coalesce
+ other protocols besides TCP. It's also safe to use with configurations that
+ are problematic for LRO, namely bridging and iSCSI.
+
+ GRO is enabled by default in the driver. Future versions of ethtool will
+ support disabling and re-enabling GRO on the fly.
+
+
+ Data Center Bridging, aka DCB
+ -----------------------------
+
+ DCB is a configuration Quality of Service implementation in hardware.
+ It uses the VLAN priority tag (802.1p) to filter traffic. That means
+ that there are 8 different priorities that traffic can be filtered into.
+ It also enables priority flow control which can limit or eliminate the
+ number of dropped packets during network stress. Bandwidth can be
+ allocated to each of these priorities, which is enforced at the hardware
+ level.
+
+ To enable DCB support in ixgbe, you must enable the DCB netlink layer to
+ allow the userspace tools (see below) to communicate with the driver.
+ This can be found in the kernel configuration here:
+
+ -> Networking support
+ -> Networking options
+ -> Data Center Bridging support
+
+ Once this is selected, DCB support must be selected for ixgbe. This can
+ be found here:
+
+ -> Device Drivers
+ -> Network device support (NETDEVICES [=y])
+ -> Ethernet (10000 Mbit) (NETDEV_10000 [=y])
+ -> Intel(R) 10GbE PCI Express adapters support
+ -> Data Center Bridging (DCB) Support
+
+ After these options are selected, you must rebuild your kernel and your
+ modules.
+
+ In order to use DCB, userspace tools must be downloaded and installed.
+ The dcbd tools can be found at:
+
+ http://e1000.sf.net
+
+
+ Ethtool
+ -------
+ The driver utilizes the ethtool interface for driver configuration and
+ diagnostics, as well as displaying statistical information. Ethtool
+ version 3.0 or later is required for this functionality.
+
+ The latest release of ethtool can be found from
+ http://sourceforge.net/projects/gkernel.
+
+
+ NAPI
+ ----
+
+ NAPI (Rx polling mode) is supported in the ixgbe driver. NAPI is enabled
+ by default in the driver.
+
+ See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.

+Overview
+========
+
+This readme tries to provide some background on the hows and whys of RDS,
+and will hopefully help you find your way around the code.
+
+In addition, please see this email about RDS origins:
+http://oss.oracle.com/pipermail/rds-devel/2007-November/000228.html
+
+RDS Architecture
+================
+
+RDS provides reliable, ordered datagram delivery by using a single
+reliable connection between any two nodes in the cluster. This allows
+applications to use a single socket to talk to any other process in the
+cluster - so in a cluster with N processes you need N sockets, in contrast
+to N*N if you use a connection-oriented socket transport like TCP.
+
+RDS is not Infiniband-specific; it was designed to support different
+transports. The current implementation used to support RDS over TCP as well
+as IB. Work is in progress to support RDS over iWARP, and using DCE to
+guarantee no dropped packets on Ethernet, it may be possible to use RDS over
+UDP in the future.
+
+The high-level semantics of RDS from the application's point of view are
+
+ * Addressing
+ RDS uses IPv4 addresses and 16bit port numbers to identify
+ the end point of a connection. All socket operations that involve
+ passing addresses between kernel and user space generally
+ use a struct sockaddr_in.
+
+ The fact that IPv4 addresses are used does not mean the underlying
+ transport has to be IP-based. In fact, RDS over IB uses a
+ reliable IB connection; the IP address is used exclusively to
+ locate the remote node's GID (by ARPing for the given IP).
+
+ The port space is entirely independent of UDP, TCP or any other
+ protocol.
+
+ * Socket interface
+ RDS sockets work *mostly* as you would expect from a BSD
+ socket. The next section will cover the details. At any rate,
+ all I/O is performed through the standard BSD socket API.
+ Some additions like zerocopy support are implemented through
+ control messages, while other extensions use the getsockopt/
+ setsockopt calls.
+
+ Sockets must be bound before you can send or receive data.
+ This is needed because binding also selects a transport and
+ attaches it to the socket. Once bound, the transport assignment
+ does not change. RDS will tolerate IPs moving around (eg in
+ a active-active HA scenario), but only as long as the address
+ doesn't move to a different transport.
+
+ * sysctls
+ RDS supports a number of sysctls in /proc/sys/net/rds
+
+
+Socket Interface
+================
+
+ AF_RDS, PF_RDS, SOL_RDS
+ These constants haven't been assigned yet, because RDS isn't in
+ mainline yet. Currently, the kernel module assigns some constant
+ and publishes it to user space through two sysctl files
+ /proc/sys/net/rds/pf_rds
+ /proc/sys/net/rds/sol_rds
+
+ fd = socket(PF_RDS, SOCK_SEQPACKET, 0);
+ This creates a new, unbound RDS socket.
+
+ setsockopt(SOL_SOCKET): send and receive buffer size
+ RDS honors the send and receive buffer size socket options.
+ You are not allowed to queue more than SO_SNDSIZE bytes to
+ a socket. A message is queued when sendmsg is called, and
+ it leaves the queue when the remote system acknowledges
+ its arrival.
+
+ The SO_RCVSIZE option controls the maximum receive queue length.
+ This is a soft limit rather than a hard limit - RDS will
+ continue to accept and queue incoming messages, even if that
+ takes the queue length over the limit. However, it will also
+ mark the port as "congested" and send a congestion update to
+ the source node. The source node is supposed to throttle any
+ processes sending to this congested port.
+
+ bind(fd, &sockaddr_in, ...)
+ This binds the socket to a local IP address and port, and a
+ transport.
+
+ sendmsg(fd, ...)
+ Sends a message to the indicated recipient. The kernel will
+ transparently establish the underlying reliable connection
+ if it isn't up yet.
+
+ An attempt to send a message that exceeds SO_SNDSIZE will
+ return with -EMSGSIZE
+
+ An attempt to send a message that would take the total number
+ of queued bytes over the SO_SNDSIZE threshold will return
+ EAGAIN.
+
+ An attempt to send a message to a destination that is marked
+ as "congested" will return ENOBUFS.
+
+ recvmsg(fd, ...)
+ Receives a message that was queued to this socket. The sockets
+ recv queue accounting is adjusted, and if the queue length
+ drops below SO_SNDSIZE, the port is marked uncongested, and
+ a congestion update is sent to all peers.
+
+ Applications can ask the RDS kernel module to receive
+ notifications via control messages (for instance, there is a
+ notification when a congestion update arrived, or when a RDMA
+ operation completes). These notifications are received through
+ the msg.msg_control buffer of struct msghdr. The format of the
+ messages is described in manpages.
+
+ poll(fd)
+ RDS supports the poll interface to allow the application
+ to implement async I/O.
+
+ POLLIN handling is pretty straightforward. When there's an
+ incoming message queued to the socket, or a pending notification,
+ we signal POLLIN.
+
+ POLLOUT is a little harder. Since you can essentially send
+ to any destination, RDS will always signal POLLOUT as long as
+ there's room on the send queue (ie the number of bytes queued
+ is less than the sendbuf size).
+
+ However, the kernel will refuse to accept messages to
+ a destination marked congested - in this case you will loop
+ forever if you rely on poll to tell you what to do.
+ This isn't a trivial problem, but applications can deal with
+ this - by using congestion notifications, and by checking for
+ ENOBUFS errors returned by sendmsg.
+
+ setsockopt(SOL_RDS, RDS_CANCEL_SENT_TO, &sockaddr_in)
+ This allows the application to discard all messages queued to a
+ specific destination on this particular socket.
+
+ This allows the application to cancel outstanding messages if
+ it detects a timeout. For instance, if it tried to send a message,
+ and the remote host is unreachable, RDS will keep trying forever.
+ The application may decide it's not worth it, and cancel the
+ operation. In this case, it would use RDS_CANCEL_SENT_TO to
+ nuke any pending messages.
+
+
+RDMA for RDS
+============
+
+ see rds-rdma(7) manpage (available in rds-tools)
+
+
+Congestion Notifications
+========================
+
+ see rds(7) manpage
+
+
+RDS Protocol
+============
+
+ Message header
+
+ The message header is a 'struct rds_header' (see rds.h):
+ Fields:
+ h_sequence:
+ per-packet sequence number
+ h_ack:
+ piggybacked acknowledgment of last packet received
+ h_len:
+ length of data, not including header
+ h_sport:
+ source port
+ h_dport:
+ destination port
+ h_flags:
+ CONG_BITMAP - this is a congestion update bitmap
+ ACK_REQUIRED - receiver must ack this packet
+ RETRANSMITTED - packet has previously been sent
+ h_credit:
+ indicate to other end of connection that
+ it has more credits available (i.e. there is
+ more send room)
+ h_padding[4]:
+ unused, for future use
+ h_csum:
+ header checksum
+ h_exthdr:
+ optional data can be passed here. This is currently used for
+ passing RDMA-related information.
+
+ ACK and retransmit handling
+
+ One might think that with reliable IB connections you wouldn't need
+ to ack messages that have been received. The problem is that IB
+ hardware generates an ack message before it has DMAed the message
+ into memory. This creates a potential message loss if the HCA is
+ disabled for any reason between when it sends the ack and before
+ the message is DMAed and processed. This is only a potential issue
+ if another HCA is available for fail-over.
+
+ Sending an ack immediately would allow the sender to free the sent
+ message from their send queue quickly, but could cause excessive
+ traffic to be used for acks. RDS piggybacks acks on sent data
+ packets. Ack-only packets are reduced by only allowing one to be
+ in flight at a time, and by the sender only asking for acks when
+ its send buffers start to fill up. All retransmissions are also
+ acked.
+
+ Flow Control
+
+ RDS's IB transport uses a credit-based mechanism to verify that
+ there is space in the peer's receive buffers for more data. This
+ eliminates the need for hardware retries on the connection.
+
+ Congestion
+
+ Messages waiting in the receive queue on the receiving socket
+ are accounted against the sockets SO_RCVBUF option value. Only
+ the payload bytes in the message are accounted for. If the
+ number of bytes queued equals or exceeds rcvbuf then the socket
+ is congested. All sends attempted to this socket's address
+ should return block or return -EWOULDBLOCK.
+
+ Applications are expected to be reasonably tuned such that this
+ situation very rarely occurs. An application encountering this
+ "back-pressure" is considered a bug.
+
+ This is implemented by having each node maintain bitmaps which
+ indicate which ports on bound addresses are congested. As the
+ bitmap changes it is sent through all the connections which
+ terminate in the local address of the bitmap which changed.
+
+ The bitmaps are allocated as connections are brought up. This
+ avoids allocation in the interrupt handling path which queues
+ sages on sockets. The dense bitmaps let transports send the
+ entire bitmap on any bitmap change reasonably efficiently. This
+ is much easier to implement than some finer-grained
+ communication of per-port congestion. The sender does a very
+ inexpensive bit test to test if the port it's about to send to
+ is congested or not.
+
+
+RDS Transport Layer
+==================
+
+ As mentioned above, RDS is not IB-specific. Its code is divided
+ into a general RDS layer and a transport layer.
+
+ The general layer handles the socket API, congestion handling,
+ loopback, stats, usermem pinning, and the connection state machine.
+
+ The transport layer handles the details of the transport. The IB
+ transport, for example, handles all the queue pairs, work requests,
+ CM event handlers, and other Infiniband details.
+
+
+RDS Kernel Structures
+=====================
+
+ struct rds_message
+ aka possibly "rds_outgoing", the generic RDS layer copies data to
+ be sent and sets header fields as needed, based on the socket API.
+ This is then queued for the individual connection and sent by the
+ connection's transport.
+ struct rds_incoming
+ a generic struct referring to incoming data that can be handed from
+ the transport to the general code and queued by the general code
+ while the socket is awoken. It is then passed back to the transport
+ code to handle the actual copy-to-user.
+ struct rds_socket
+ per-socket information
+ struct rds_connection
+ per-connection information
+ struct rds_transport
+ pointers to transport-specific functions
+ struct rds_statistics
+ non-transport-specific statistics
+ struct rds_cong_map
+ wraps the raw congestion bitmap, contains rbnode, waitq, etc.
+
+Connection management
+=====================
+
+ Connections may be in UP, DOWN, CONNECTING, DISCONNECTING, and
+ ERROR states.
+
+ The first time an attempt is made by an RDS socket to send data to
+ a node, a connection is allocated and connected. That connection is
+ then maintained forever -- if there are transport errors, the
+ connection will be dropped and re-established.
+
+ Dropping a connection while packets are queued will cause queued or
+ partially-sent datagrams to be retransmitted when the connection is
+ re-established.
+
+
+The send path
+=============
+
+ rds_sendmsg()
+ struct rds_message built from incoming data
+ CMSGs parsed (e.g. RDMA ops)
+ transport connection alloced and connected if not already
+ rds_message placed on send queue
+ send worker awoken
+ rds_send_worker()
+ calls rds_send_xmit() until queue is empty
+ rds_send_xmit()
+ transmits congestion map if one is pending
+ may set ACK_REQUIRED
+ calls transport to send either non-RDMA or RDMA message
+ (RDMA ops never retransmitted)
+ rds_ib_xmit()
+ allocs work requests from send ring
+ adds any new send credits available to peer (h_credits)
+ maps the rds_message's sg list
+ piggybacks ack
+ populates work requests
+ post send to connection's queue pair
+
+The recv path
+=============
+
+ rds_ib_recv_cq_comp_handler()
+ looks at write completions
+ unmaps recv buffer from device
+ no errors, call rds_ib_process_recv()
+ refill recv ring
+ rds_ib_process_recv()
+ validate header checksum
+ copy header to rds_ib_incoming struct if start of a new datagram
+ add to ibinc's fraglist
+ if competed datagram:
+ update cong map if datagram was cong update
+ call rds_recv_incoming() otherwise
+ note if ack is required
+ rds_recv_incoming()
+ drop duplicate packets
+ respond to pings
+ find the sock associated with this datagram
+ add to sock queue
+ wake up sock
+ do some congestion calculations
+ rds_recvmsg
+ copy data into user iovec
+ handle CMSGs
+ return to application

+The existing interfaces for getting network packages time stamped are:
+
+* SO_TIMESTAMP
+ Generate time stamp for each incoming packet using the (not necessarily
+ monotonous!) system time. Result is returned via recv_msg() in a
+ control message as timeval (usec resolution).
+
+* SO_TIMESTAMPNS
+ Same time stamping mechanism as SO_TIMESTAMP, but returns result as
+ timespec (nsec resolution).
+
+* IP_MULTICAST_LOOP + SO_TIMESTAMP[NS]
+ Only for multicasts: approximate send time stamp by receiving the looped
+ packet and using its receive time stamp.
+
+The following interface complements the existing ones: receive time
+stamps can be generated and returned for arbitrary packets and much
+closer to the point where the packet is really sent. Time stamps can
+be generated in software (as before) or in hardware (if the hardware
+has such a feature).
+
+SO_TIMESTAMPING:
+
+Instructs the socket layer which kind of information is wanted. The
+parameter is an integer with some of the following bits set. Setting
+other bits is an error and doesn't change the current state.
+
+SOF_TIMESTAMPING_TX_HARDWARE: try to obtain send time stamp in hardware
+SOF_TIMESTAMPING_TX_SOFTWARE: if SOF_TIMESTAMPING_TX_HARDWARE is off or
+ fails, then do it in software
+SOF_TIMESTAMPING_RX_HARDWARE: return the original, unmodified time stamp
+ as generated by the hardware
+SOF_TIMESTAMPING_RX_SOFTWARE: if SOF_TIMESTAMPING_RX_HARDWARE is off or
+ fails, then do it in software
+SOF_TIMESTAMPING_RAW_HARDWARE: return original raw hardware time stamp
+SOF_TIMESTAMPING_SYS_HARDWARE: return hardware time stamp transformed to
+ the system time base
+SOF_TIMESTAMPING_SOFTWARE: return system time stamp generated in
+ software
+
+SOF_TIMESTAMPING_TX/RX determine how time stamps are generated.
+SOF_TIMESTAMPING_RAW/SYS determine how they are reported in the
+following control message:
+ struct scm_timestamping {
+ struct timespec systime;
+ struct timespec hwtimetrans;
+ struct timespec hwtimeraw;
+ };
+
+recvmsg() can be used to get this control message for regular incoming
+packets. For send time stamps the outgoing packet is looped back to
+the socket's error queue with the send time stamp(s) attached. It can
+be received with recvmsg(flags=MSG_ERRQUEUE). The call returns the
+original outgoing packet data including all headers preprended down to
+and including the link layer, the scm_timestamping control message and
+a sock_extended_err control message with ee_errno==ENOMSG and
+ee_origin==SO_EE_ORIGIN_TIMESTAMPING. A socket with such a pending
+bounced packet is ready for reading as far as select() is concerned.
+If the outgoing packet has to be fragmented, then only the first
+fragment is time stamped and returned to the sending socket.
+
+All three values correspond to the same event in time, but were
+generated in different ways. Each of these values may be empty (= all
+zero), in which case no such value was available. If the application
+is not interested in some of these values, they can be left blank to
+avoid the potential overhead of calculating them.
+
+systime is the value of the system time at that moment. This
+corresponds to the value also returned via SO_TIMESTAMP[NS]. If the
+time stamp was generated by hardware, then this field is
+empty. Otherwise it is filled in if SOF_TIMESTAMPING_SOFTWARE is
+set.
+
+hwtimeraw is the original hardware time stamp. Filled in if
+SOF_TIMESTAMPING_RAW_HARDWARE is set. No assumptions about its
+relation to system time should be made.
+
+hwtimetrans is the hardware time stamp transformed so that it
+corresponds as good as possible to system time. This correlation is
+not perfect; as a consequence, sorting packets received via different
+NICs by their hwtimetrans may differ from the order in which they were
+received. hwtimetrans may be non-monotonic even for the same NIC.
+Filled in if SOF_TIMESTAMPING_SYS_HARDWARE is set. Requires support
+by the network device and will be empty without that support.
+
+
+SIOCSHWTSTAMP:
+
+Hardware time stamping must also be initialized for each device driver
+that is expected to do hardware time stamping. The parameter is:
+
+struct hwtstamp_config {
+ int flags; /* no flags defined right now, must be zero */
+ int tx_type; /* HWTSTAMP_TX_* */
+ int rx_filter; /* HWTSTAMP_FILTER_* */
+};
+
+Desired behavior is passed into the kernel and to a specific device by
+calling ioctl(SIOCSHWTSTAMP) with a pointer to a struct ifreq whose
+ifr_data points to a struct hwtstamp_config. The tx_type and
+rx_filter are hints to the driver what it is expected to do. If
+the requested fine-grained filtering for incoming packets is not
+supported, the driver may time stamp more than just the requested types
+of packets.
+
+A driver which supports hardware time stamping shall update the struct
+with the actual, possibly more permissive configuration. If the
+requested packets cannot be time stamped, then nothing should be
+changed and ERANGE shall be returned (in contrast to EINVAL, which
+indicates that SIOCSHWTSTAMP is not supported at all).
+
+Only a processes with admin rights may change the configuration. User
+space is responsible to ensure that multiple processes don't interfere
+with each other and that the settings are reset.
+

+
+
+DEVICE IMPLEMENTATION
+
+A driver which supports hardware time stamping must support the
+SIOCSHWTSTAMP ioctl. Time stamps for received packets must be stored
+in the skb with skb_hwtstamp_set().
+
+Time stamps for outgoing packets are to be generated as follows:
+- In hard_start_xmit(), check if skb_hwtstamp_check_tx_hardware()
+ returns non-zero. If yes, then the driver is expected
+ to do hardware time stamping.
+- If this is possible for the skb and requested, then declare
+ that the driver is doing the time stamping by calling
+ skb_hwtstamp_tx_in_progress(). A driver not supporting
+ hardware time stamping doesn't do that. A driver must never
+ touch sk_buff::tstamp! It is used to store how time stamping
+ for an outgoing packets is to be done.
+- As soon as the driver has sent the packet and/or obtained a
+ hardware time stamp for it, it passes the time stamp back by
+ calling skb_hwtstamp_tx() with the original skb, the raw
+ hardware time stamp and a handle to the device (necessary
+ to convert the hardware time stamp to system time). If obtaining
+ the hardware time stamp somehow fails, then the driver should
+ not fall back to software time stamping. The rationale is that
+ this would occur at a later time in the processing pipeline
+ than other software time stamping and therefore could lead
+ to unexpected deltas between time stamps.
+- If the driver did not call skb_hwtstamp_tx_in_progress(), then
+ dev_hard_start_xmit() checks whether software time stamping
+ is wanted as fallback and potentially generates the time stamp.

- Reference for various scheduler-related methods in the O(1) scheduler
- Robert Love , MontaVista Software
-
-
-Note most of these methods are local to kernel/sched.c - this is by design.
-The scheduler is meant to be self-contained and abstracted away. This document
-is primarily for understanding the scheduler, not interfacing to it. Some of
-the discussed interfaces, however, are general process/scheduling methods.
-They are typically defined in include/linux/sched.h.
-
-
-Main Scheduling Methods
------------------------
-
-void load_balance(runqueue_t *this_rq, int idle)
- Attempts to pull tasks from one cpu to another to balance cpu usage,
- if needed. This method is called explicitly if the runqueues are
- imbalanced or periodically by the timer tick. Prior to calling,
- the current runqueue must be locked and interrupts disabled.
-
-void schedule()
- The main scheduling function. Upon return, the highest priority
- process will be active.
-
-
-Locking
--------
-
-Each runqueue has its own lock, rq->lock. When multiple runqueues need
-to be locked, lock acquires must be ordered by ascending &runqueue value.
-
-A specific runqueue is locked via
-
- task_rq_lock(task_t pid, unsigned long *flags)
-
-which disables preemption, disables interrupts, and locks the runqueue pid is
-running on. Likewise,
-
- task_rq_unlock(task_t pid, unsigned long *flags)
-
-unlocks the runqueue pid is running on, restores interrupts to their previous
-state, and reenables preemption.
-
-The routines
-
- double_rq_lock(runqueue_t *rq1, runqueue_t *rq2)
-
-and
-
- double_rq_unlock(runqueue_t *rq1, runqueue_t *rq2)
-
-safely lock and unlock, respectively, the two specified runqueues. They do
-not, however, disable and restore interrupts. Users are required to do so
-manually before and after calls.
-
-
-Values
-------
-
-MAX_PRIO
- The maximum priority of the system, stored in the task as task->prio.
- Lower priorities are higher. Normal (non-RT) priorities range from
- MAX_RT_PRIO to (MAX_PRIO - 1).
-MAX_RT_PRIO
- The maximum real-time priority of the system. Valid RT priorities
- range from 0 to (MAX_RT_PRIO - 1).
-MAX_USER_RT_PRIO
- The maximum real-time priority that is exported to user-space. Should
- always be equal to or less than MAX_RT_PRIO. Setting it less allows
- kernel threads to have higher priorities than any user-space task.
-MIN_TIMESLICE
-MAX_TIMESLICE
- Respectively, the minimum and maximum timeslices (quanta) of a process.
-
-Data
-----
-
-struct runqueue
- The main per-CPU runqueue data structure.
-struct task_struct
- The main per-process data structure.
-
-
-General Methods
----------------
-
-cpu_rq(cpu)
- Returns the runqueue of the specified cpu.
-this_rq()
- Returns the runqueue of the current cpu.
-task_rq(pid)
- Returns the runqueue which holds the specified pid.
-cpu_curr(cpu)
- Returns the task currently running on the given cpu.
-rt_task(pid)
- Returns true if pid is real-time, false if not.
-
-
-Process Control Methods
------------------------
