+#### cli()/sti() removal guide, started by Ingo Molnar <mingo@redhat.com>
+
+
+as of 2.5.28, five popular macros have been removed on SMP, and
+are being phased out on UP:
+
+ cli(), sti(), save_flags(flags), save_flags_cli(flags), restore_flags(flags)
+
+until now it was possible to protect driver code against interrupt
+handlers via a cli(), but from now on other, more lightweight methods
+have to be used for synchronization, such as spinlocks or semaphores.
+
+for example, driver code that used to do something like:
+
+ struct driver_data;
+
+ irq_handler (...)
+ {
+ ....
+ driver_data.finish = 1;
+ driver_data.new_work = 0;
+ ....
+ }
+
+ ...
+
+ ioctl_func (...)
+ {
+ ...
+ cli();
+ ...
+ driver_data.finish = 0;
+ driver_data.new_work = 2;
+ ...
+ sti();
+ ...
+ }
+
+was SMP-correct because the cli() function ensured that no
+interrupt handler (amongst them the above irq_handler()) function
+would execute while the cli()-ed section is executing.
+
+but from now on a more direct method of locking has to be used:
+
+ spinlock_t driver_lock = SPIN_LOCK_UNLOCKED;
+ struct driver_data;
+
+ irq_handler (...)
+ {
+ unsigned long flags;
+ ....
+ spin_lock_irqsave(&driver_lock, flags);
+ ....
+ driver_data.finish = 1;
+ driver_data.new_work = 0;
+ ....
+ spin_unlock_irqrestore(&driver_lock, flags);
+ ....
+ }
+
+ ...
+
+ ioctl_func (...)
+ {
+ ...
+ spin_lock_irq(&driver_lock);
+ ...
+ driver_data.finish = 0;
+ driver_data.new_work = 2;
+ ...
+ spin_unlock_irq(&driver_lock);
+ ...
+ }
+
+the above code has a number of advantages:
+
+- the locking relation is easier to understand - actual lock usage
+ pinpoints the critical sections. cli() usage is too opaque.
+ Easier to understand means it's easier to debug.
+
+- it's faster, because spinlocks are faster to acquire than the
+ potentially heavily-used IRQ lock. Furthermore, your driver does
+ not have to wait eg. for a big heavy SCSI interrupt to finish,
+ because the driver_lock spinlock is only used by your driver.
+ cli() on the other hand was used by many drivers, and extended
+ the critical section to the whole IRQ handler function - creating
+ serious lock contention.
+
+
+to make the transition easier, we've still kept the cli(), sti(),
+save_flags(), save_flags_cli() and restore_flags() macros defined
+on UP systems - but their usage will be phased out until 2.6 is
+released.
+
+drivers that want to disable local interrupts (interrupts on the
+current CPU), can use the following five macros:
+
+ local_irq_disable(), local_irq_enable(), local_irq_save(flags),
+ local_irq_save_off(flags), local_irq_restore(flags)
+
+but beware, their meaning and semantics are much simpler, far from
+that of the old cli(), sti(), save_flags(flags) and restore_flags(flags)
+SMP meaning:
+
+ local_irq_disable() => turn local IRQs off
+
+ local_irq_enable() => turn local IRQs on
+
+ local_irq_save(flags) => save the current IRQ state into flags. The
+ state can be on or off. (on some
+ architectures there's even more bits in it.)
+
+ local_irq_save_off(flags) => save the current IRQ state into flags and
+ disable interrupts.
+
+ local_irq_restore(flags) => restore the IRQ state from flags.
+
+(local_irq_save can save both irqs on and irqs off state, and
+local_irq_restore can restore into both irqs on and irqs off state.)
+
+another related change is that synchronize_irq() now takes a parameter:
+synchronize_irq(irq). This change too has the purpose of making SMP
+to make the transition easier, we've still kept the cli(), sti(),
+save_flags() and restore_flags() macros defined on UP systems - but
+their usage will be phased out until the 2.6 kernel is released.
+
+
+why were these changes done? The main reason was the architectural burden
+of maintaining the cli()/sti() interface - it became a real problem. The
+new interrupt system is much more streamlined, easier to understand, debug,
+and it's also a bit faster - the same happened to it that will happen to
+cli()/sti() using drivers once they convert to spinlocks :-)

+ Low Level Serial API
+ --------------------
+
+
+ $Id: driver,v 1.9 2002/07/06 16:51:43 rmk Exp $
+
+
+This document is meant as a brief overview of some aspects of the new serial
+driver. It is not complete, any questions you have should be directed to
+<rmk@arm.linux.org.uk>
+
+The reference implementation is contained within serial_amba.c.
+
+
+
+Low Level Serial Hardware Driver
+--------------------------------
+
+The low level serial hardware driver is responsible for supplying port
+information (defined by uart_port) and a set of control methods (defined
+by uart_ops) to the core serial driver. The low level driver is also
+responsible for handling interrupts for the port, and providing any
+console support.
+
+
+Console Support
+---------------
+
+The serial core provides a few helper functions. This includes identifing
+the correct port structure (via uart_get_console) and decoding command line
+arguments (uart_parse_options).
+
+
+Locking
+-------
+
+It is the responsibility of the low level hardware driver to perform the
+necessary locking using port->lock. There are some exceptions (which
+are described in the uart_ops listing below.)
+
+There are three locks. A per-port spinlock, a per-port tmpbuf semaphore,
+and an overall semaphore.
+
+From the core driver perspective, the port->lock locks the following
+data:
+
+ port->mctrl
+ port->icount
+ info->xmit.head (circ->head)
+ info->xmit.tail (circ->tail)
+
+The low level driver is free to use this lock to provide any additional
+locking.
+
+The core driver uses the info->tmpbuf_sem lock to prevent multi-threaded
+access to the info->tmpbuf bouncebuffer used for port writes.
+
+The port_sem semaphore is used to protect against ports being added/
+removed or reconfigured at inappropriate times.
+
+
+uart_ops
+--------
+
+The uart_ops structure is the main interface between serial_core and the
+hardware specific driver. It contains all the methods to control the
+hardware.
+
+ tx_empty(port)
+ This function tests whether the transmitter fifo and shifter
+ for the port described by 'port' is empty. If it is empty,
+ this function should return TIOCSER_TEMT, otherwise return 0.
+ If the port does not support this operation, then it should
+ return TIOCSER_TEMT.
+
+ Locking: none.
+ Interrupts: caller dependent.
+ This call must not sleep
+
+ set_mctrl(port, mctrl)
+ This function sets the modem control lines for port described
+ by 'port' to the state described by mctrl. The relevant bits
+ of mctrl are:
+ - TIOCM_RTS RTS signal.
+ - TIOCM_DTR DTR signal.
+ - TIOCM_OUT1 OUT1 signal.
+ - TIOCM_OUT2 OUT2 signal.
+ If the appropriate bit is set, the signal should be driven
+ active. If the bit is clear, the signal should be driven
+ inactive.
+
+ Locking: port->lock taken.
+ Interrupts: locally disabled.
+ This call must not sleep
+
+ get_mctrl(port)
+ Returns the current state of modem control inputs. The state
+ of the outputs should not be returned, since the core keeps
+ track of their state. The state information should include:
+ - TIOCM_DCD state of DCD signal
+ - TIOCM_CTS state of CTS signal
+ - TIOCM_DSR state of DSR signal
+ - TIOCM_RI state of RI signal
+ The bit is set if the signal is currently driven active. If
+ the port does not support CTS, DCD or DSR, the driver should
+ indicate that the signal is permanently active. If RI is
+ not available, the signal should not be indicated as active.
+
+ Locking: none.
+ Interrupts: caller dependent.
+ This call must not sleep
+
+ stop_tx(port,tty_stop)
+ Stop transmitting characters. This might be due to the CTS
+ line becoming inactive or the tty layer indicating we want
+ to stop transmission.
+
+ tty_stop: 1 if this call is due to the TTY layer issuing a
+ TTY stop to the driver (equiv to rs_stop).
+
+ Locking: none.
+ Interrupts: caller dependent.
+ This call must not sleep
+
+ start_tx(port,tty_start)
+ start transmitting characters. (incidentally, nonempty will
+ always be nonzero, and shouldn't be used - it will be dropped).
+
+ tty_start: 1 if this call was due to the TTY layer issuing
+ a TTY start to the driver (equiv to rs_start)
+
+ Locking: port->lock taken.
+ Interrupts: locally disabled.
+ This call must not sleep
+
+ stop_rx(port)
+ Stop receiving characters; the port is in the process of
+ being closed.

+ Interrupts: caller dependent.
+ This call must not sleep
+
+ enable_ms(port)
+ Enable the modem status interrupts.
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+ break_ctl(port,ctl)
+ Control the transmission of a break signal. If ctl is
+ nonzero, the break signal should be transmitted. The signal
+ should be terminated when another call is made with a zero
+ ctl.
+
+ Locking: none.
+ Interrupts: caller dependent.
+ This call must not sleep
+
+ startup(port)
+ Grab any interrupt resources and initialise any low level driver
+ state. Enable the port for reception. It should not activate
+ RTS nor DTR; this will be done via a separate call to set_mctrl.
+
+ Locking: port_sem taken.
+ Interrupts: globally disabled.
+
+ shutdown(port)
+ Disable the port, disable any break condition that may be in
+ effect, and free any interrupt resources. It should not disable
+ RTS nor DTR; this will have already been done via a separate
+ call to set_mctrl.
+
+ Locking: port_sem taken.
+ Interrupts: caller dependent.
+
+ change_speed(port,cflag,iflag,quot)
+ Change the port parameters, including word length, parity, stop
+ bits. Update read_status_mask and ignore_status_mask to indicate
+ the types of events we are interested in receiving. Relevant
+ cflag bits are:
+ CSIZE - word size
+ CSTOPB - 2 stop bits
+ PARENB - parity enable
+ PARODD - odd parity (when PARENB is in force)
+ CREAD - enable reception of characters (if not set,
+ still receive characters from the port, but
+ throw them away.
+ CRTSCTS - if set, enable CTS status change reporting
+ CLOCAL - if not set, enable modem status change
+ reporting.
+ Relevant iflag bits are:
+ INPCK - enable frame and parity error events to be
+ passed to the TTY layer.
+ BRKINT
+ PARMRK - both of these enable break events to be
+ passed to the TTY layer.
+
+ IGNPAR - ignore parity and framing errors
+ IGNBRK - ignore break errors, If IGNPAR is also
+ set, ignore overrun errors as well.
+ The interaction of the iflag bits is as follows (parity error
+ given as an example):
+ Parity error INPCK IGNPAR
+ None n/a n/a character received
+ Yes n/a 0 character discarded
+ Yes 0 1 character received, marked as
+ TTY_NORMAL
+ Yes 1 1 character received, marked as
+ TTY_PARITY
+
+ Locking: none.
+ Interrupts: caller dependent.
+ This call must not sleep
+
+ pm(port,state,oldstate)
+ perform any power management related activities on the specified
+ port. state indicates the new state (defined by ACPI D0-D3),
+ oldstate indicates the previous state. Essentially, D0 means
+ fully on, D3 means powered down.
+
+ This function should not be used to grab any resources.
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+ type(port)
+ Return a pointer to a string constant describing the specified
+ port, or return NULL, in which case the string 'unknown' is
+ substituted.
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+ release_port(port)
+ Release any memory and IO region resources currently in use by
+ the port.
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+ request_port(port)
+ Request any memory and IO region resources required by the port.
+ If any fail, no resources should be registered when this function
+ returns, and it should return -EBUSY on failure.
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+ config_port(port,type)
+ Perform any autoconfiguration steps required for the port. `type`
+ contains a bit mask of the required configuration. UART_CONFIG_TYPE
+ indicates that the port requires detection and identification.
+ port->type should be set to the type found, or PORT_UNKNOWN if
+ no port was detected.
+
+ UART_CONFIG_IRQ indicates autoconfiguration of the interrupt signal,
+ which should be probed using standard kernel autoprobing techniques.
+ This is not necessary on platforms where ports have interrupts
+ internally hard wired (eg, system on a chip implementations).
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+ verify_port(port,serinfo)
+ Verify the new serial port information contained within serinfo is
+ suitable for this port type.
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+ ioctl(port,cmd,arg)
+ Perform any port specific IOCTLs. IOCTL commands must be defined
+ using the standard numbering system found in <asm/ioctl.h>
+
+ Locking: none.
+ Interrupts: caller dependent.
+
+
+Other notes
+-----------
+
+It is intended some day to drop the 'unused' entries from uart_port, and
+allow low level drivers to register their own individual uart_port's with
+the core. This will allow drivers to use uart_port as a pointer to a
+structure containing both the uart_port entry with their own extensions,
+thus:
+
+ struct my_port {
+ struct uart_port port;
+ int my_stuff;
+ };

+
+CONFIG_SERIAL_8250
+ This selects whether you want to include the driver for the standard
+ serial ports. The standard answer is Y. People who might say N
+ here are those that are setting up dedicated Ethernet WWW/FTP
+ servers, or users that have one of the various bus mice instead of a
+ serial mouse and don't intend to use their machine's standard serial
+ port for anything. (Note that the Cyclades and Stallion multi
+ serial port drivers do not need this driver built in for them to
+ work.)
+
+ If you want to compile this driver as a module, say M here and read
+ <file:Documentation/modules.txt>. The module will be called
+ serial.o.
+ [WARNING: Do not compile this driver as a module if you are using
+ non-standard serial ports, since the configuration information will
+ be lost when the driver is unloaded. This limitation may be lifted
+ in the future.]
+
+ BTW1: If you have a mouseman serial mouse which is not recognized by
+ the X window system, try running gpm first.
+
+ BTW2: If you intend to use a software modem (also called Winmodem)
+ under Linux, forget it. These modems are crippled and require
+ proprietary drivers which are only available under Windows.
+
+ Most people will say Y or M here, so that they can use serial mice,
+ modems and similar devices connecting to the standard serial ports.
+
+CONFIG_SERIAL_8250_CONSOLE
+ If you say Y here, it will be possible to use a serial port as the
+ system console (the system console is the device which receives all
+ kernel messages and warnings and which allows logins in single user
+ mode). This could be useful if some terminal or printer is connected
+ to that serial port.
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttyS1". (Try "man bootparam" or see the documentation of
+ your boot loader (lilo or loadlin) about how to pass options to the
+ kernel at boot time.)
+
+ If you don't have a VGA card installed and you say Y here, the
+ kernel will automatically use the first serial line, /dev/ttyS0, as
+ system console.
+
+ If unsure, say N.
+
+CONFIG_SERIAL_8250_CS
+ Say Y here to enable support for 16-bit PCMCIA serial devices,
+ including serial port cards, modems, and the modem functions of
+ multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are
+ credit-card size devices often used with laptops.)
+
+ This driver is also available as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module will be called serial_cs.o. If you want to compile it as
+ a module, say M here and read <file:Documentation/modules.txt>.
+ If unsure, say N.
+
+CONFIG_SERIAL_8250_EXTENDED
+ If you wish to use any non-standard features of the standard "dumb"
+ driver, say Y here. This includes HUB6 support, shared serial
+ interrupts, special multiport support, support for more than the
+ four COM 1/2/3/4 boards, etc.
+
+ Note that the answer to this question won't directly affect the
+ kernel: saying N will just cause the configurator to skip all
+ the questions about serial driver options. If unsure, say N.
+
+CONFIG_SERIAL_8250_MANY_PORTS
+ Say Y here if you have dumb serial boards other than the four
+ standard COM 1/2/3/4 ports. This may happen if you have an AST
+ FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
+ from <http://www.linuxdoc.org/docs.html#howto>), or other custom
+ serial port hardware which acts similar to standard serial port
+ hardware. If you only use the standard COM 1/2/3/4 ports, you can
+ say N here to save some memory. You can also say Y if you have an
+ "intelligent" multiport card such as Cyclades, Digiboards, etc.
+
+CONFIG_SERIAL_8250_SHARE_IRQ
+ Some serial boards have hardware support which allows multiple dumb
+ serial ports on the same board to share a single IRQ. To enable
+ support for this in the serial driver, say Y here.
+
+CONFIG_SERIAL_8250_DETECT_IRQ
+ Say Y here if you want the kernel to try to guess which IRQ
+ to use for your serial port.
+
+ This is considered unsafe; it is far better to configure the IRQ in
+ a boot script using the setserial command.
+
+ If unsure, say N.
+
+CONFIG_SERIAL_8250_MULTIPORT
+ Some multiport serial ports have special ports which are used to
+ signal when there are any serial ports on the board which need
+ servicing. Say Y here to enable the serial driver to take advantage
+ of those special I/O ports.
+
+CONFIG_SERIAL_8250_RSA
+ ::: To be written :::
+
+CONFIG_ATOMWIDE_SERIAL
+ If you have an Atomwide Serial card for an Acorn system, say Y to
+ this option. The driver can handle 1, 2, or 3 port cards.
+ If unsure, say N.
+
+CONFIG_DUALSP_SERIAL
+ If you have the Serial Port's dual serial card for an Acorn system,
+ say Y to this option. If unsure, say N.
+
+CONFIG_SERIAL_ANAKIN
+ ::: To be written :::
+CONFIG_SERIAL_ANAKIN_CONSOLE
+ ::: To be written :::
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttyAN0". (Try "man bootparam" or see the documentation of
+ your boot loader (lilo or loadlin) about how to pass options to the
+ kernel at boot time.)
+
+CONFIG_ANAKIN_DEFAULT_BAUDRATE
+ ::: To be written :::
+
+CONFIG_SERIAL_AMBA
+ This selects the ARM(R) AMBA(R) PrimeCell UART. If you have an
+ Integrator platform, say Y or M here.
+
+ If unsure, say N.
+
+CONFIG_SERIAL_AMBA_CONSOLE
+ Say Y here if you wish to use an AMBA PrimeCell UART as the system
+ console (the system console is the device which receives all kernel
+ messages and warnings and which allows logins in single user mode).
+
+ Even if you say Y here, the currently visible framebuffer console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttyAM0". (Try "man bootparam" or see the documentation of
+ your boot loader (lilo or loadlin) about how to pass options to the
+ kernel at boot time.)
+
+CONFIG_SERIAL_CLPS711X
+ ::: To be written :::
+
+CONFIG_SERIAL_CLPS711X_CONSOLE
+ ::: To be written :::
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but

+ your boot loader (lilo or loadlin) about how to pass options to the
+ kernel at boot time.)
+
+CONFIG_SERIAL_CLPS711X_OLD_NAME
+ ::: To be written :::
+
+CONFIG_SERIAL_21285
+ If you have a machine based on a 21285 (Footbridge) StrongARM(R)/
+ PCI bridge you can enable its onboard serial port by enabling this
+ option.
+
+CONFIG_SERIAL_21285_OLD
+ Use the old /dev/ttyS name, major 4 minor 64. This is obsolete
+ and will be removed during later 2.5 development.
+
+CONFIG_SERIAL_21285_CONSOLE
+ If you have enabled the serial port on the 21285 footbridge you can
+ make it the console by answering Y to this option.
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttyFB". (Try "man bootparam" or see the documentation of
+ your boot loader (lilo or loadlin) about how to pass options to the
+ kernel at boot time.)
+
+CONFIG_SERIAL_UART00
+ Say Y here if you want to use the hard logic uart on Excalibur. This
+ driver also supports soft logic implentations of this uart core.
+
+CONFIG_SERIAL_UART00_CONSOLE
+ Say Y here if you want to support a serial console on an Excalibur
+ hard logic uart or uart00 IP core.
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttyS1". (Try "man bootparam" or see the documentation of
+ your boot loader (lilo or loadlin) about how to pass options to the
+ kernel at boot time.)
+
+CONFIG_SERIAL_SA1100
+ If you have a machine based on a SA1100/SA1110 StrongARM(R) CPU you
+ can enable its onboard serial port by enabling this option.
+ Please read <file:Documentation/arm/SA1100/serial_UART> for further
+ info.
+
+CONFIG_SERIAL_SA1100_CONSOLE
+ If you have enabled the serial port on the SA1100/SA1110 StrongARM
+ CPU you can make it the console by answering Y to this option.
+
+ Even if you say Y here, the currently visible virtual console
+ (/dev/tty0) will still be used as the system console by default, but
+ you can alter that using a kernel command line option such as
+ "console=ttySA0". (Try "man bootparam" or see the documentation of
+ your boot loader (lilo or loadlin) about how to pass options to the
+ kernel at boot time.)
+
+#CONFIG_SERIAL_L7200
+# If you have a LinkUp Systems L7200 board you can enable its two
+# onboard serial ports by enabling this option. The device numbers
