However 32-bit x86 processors have only 4 Gigabytes of - virtual memory space. This option specifies the maximum amount of - virtual memory space one process can potentially use. Certain types - of applications (eg. database servers) perform better if they have - as much virtual memory per process as possible. - - The remaining part of the 4G virtual memory space is used by the - kernel to 'permanently map' as much physical memory as possible. - Certain types of applications perform better if there is more - 'permanently mapped' kernel memory. - - [WARNING! Certain boards do not support PCI DMA to physical addresses - bigger than 2 Gigabytes. Non-DMA-able memory must not be permanently - mapped by the kernel, thus a 1G/3G split will not work on such boxes.] - - As you can see there is no 'perfect split' - the fundamental - problem is that 4G of 32-bit virtual memory space is short. So - you'll have to pick your own choice - depending on the application - load of your box. A 2G/2G split is typically a good choice for a - generic Linux server with lots of RAM. - - Any potentially remaining (not permanently mapped) part of physical - memory is called 'high memory'. How much total high memory the kernel - can handle is influenced by the (next) High Memory configuration option. - - The actual amount of total physical memory will either be - autodetected or can be forced by using a kernel command line option - such as "mem=256M". (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.

First of all, {\em please\/} include the -word ``device'' in the subject so your mail won't accidentally get -buried! I receive hundreds of email messages a day, so mail sent with -other subjects may very well get lost in the avalanche. - -Second, please include a description of the device {\em in the same -format as this list\/}.

A -terminal device is any device that could act as a controlling terminal -for a session; this includes virtual consoles, serial ports, and -pseudoterminals (PTYs). - -All terminal devices share a common set of capabilities known as line -diciplines; these include the common terminal line dicipline as well -as SLIP and PPP modes. - -All terminal devices are named similarly; this section explains the -naming and use of the various types of TTYs. Note that the naming -conventions include several historical warts; some of these are -Linux-specific, some were inherited from other systems, and some -reflect Linux outgrowing a borrowed convention. - -A hash mark ($\#$) in a device name is in all cases used here to -indicate a decimal number without leading zeroes. - -\subsection{Virtual consoles and the console device} - -Virtual consoles are full-screen terminal displays on the system video -monitor. Virtual consoles are named {\file /dev/tty$\#$}, with -numbering starting at {\file /dev/tty1}; {\file /dev/tty0} is the -current virtual console. {\file /dev/tty0} is the device that should -be used to access the system video card on those architectures for -which the frame buffer devices ({\file /dev/fb*}) are not applicable. -Do not use {\file /dev/console} for this purpose. - -The {\em console device\/}, {\file /dev/console}, is the device to -which system messages should be sent, and on which logins should be -permitted in single-user mode. Starting with Linux 2.1.71, {\file -/dev/console} is managed by the kernel; for previous versions it -should be a symbolic link to either {\file /dev/tty0}, a specific -virtual console such as {\file /dev/tty1}, or to a serial port primary -({\file tty*}, not {\file cu*}) device, depending on the configuration -of the system. - -\subsection{Serial ports} - -Serial ports are RS-232 serial ports and any device which simulates -one, either in hardware (such as internal modems) or in software (such -as the ISDN driver.) Under Linux, each serial ports has two device -names, the primary or callin device and the alternate or callout one. -Each kind of device is indicated by a different letter. For any -letter $X$, the names of the devices are {\file /dev/tty${X\#}$} and -{\file /dev/cu${x\#}$}, respectively; for historical reasons, {\file -/dev/ttyS$\#$} and {\file /dev/ttyC$\#$} correspond to {\file -/dev/cua$\#$} and {\file /dev/cub$\#$}. In the future, it should be -expected that multiple letters will be used; all letters will be upper -case for the {\file tty} device (e.g. {\file /dev/ttyDP$\#$} and lower -case for the {\file cu} device (e.g. {\file /dev/cudp$\#$}. - -The use of the callout devices is deprecated. - -The names {\file /dev/ttyQ$\#$} and {\file /dev/cuq$\#$} are reserved -for local use. - -The alternate devices provide for kernel-based exclusion and somewhat -different defaults than the primary devices. Their main purpose is to -allow the use of serial ports with programs with no inherent or broken -support for serial ports. Their use is deprecated, and they may be -removed from a future version of Linux. - -Arbitration of serial ports is provided by the use of lock files with -the names {\file /var/lock/LCK..tty${X\#}$}. The contents of the lock -file should be the PID of the locking process as an ASCII number. - -It is common practice to install links such as {\file /dev/modem\/} -which point to serial ports. In order to ensure proper locking in the -presence of these links, it is recommended that software chase -symlinks and lock all possible names; additionally, it is recommended -that a lock file be installed with the corresponding alternate -device. In order to avoid deadlocks, it is recommended that the locks -are acquired in the following order, and released in the reverse: -\begin{itemize} -\item{The symbolic link name, if any ({\file /var/lock/LCK..modem})} -\item{The {\file tty} name ({\file /var/lock/LCK..ttyS2})} -\item{The alternate device name ({\file /var/lock/LCK..cua2})} -\end{itemize} -In the case of nested symbolic links, the lock files should be -installed in the order the symlinks are resolved. - -Under no circumstances should an application hold a lock while waiting -for another to be released. In addition, applications which attempt -to create lock files for the corresponding alternate device names -should take into account the possibility of being used on a non-serial -port TTY, for which no alternate device would exist. - -\subsection{Pseudoterminals (PTYs)} - -Pseudoterminals, or PTYs, are used to create login sessions or provide -other capabilities requiring a TTY line dicipline (including SLIP or -PPP capability) to arbitrary data-generation processes. Each PTY has -a {\em master\/} side, named {\file /dev/pty[p-za-e][0-9a-f]\/}, and a -{\em slave\/} side, named {\file /dev/tty[p-za-e][0-9a-f]\/}. The -kernel arbitrates the use of PTYs by allowing each master side to be -opened only once. - -Once the master side has been opened, the corresponding slave device -can be used in the same manner as any TTY device. The master and -slave devices are connected by the kernel, generating the equivalent -of a bidirectional pipe with TTY capabilities. - -Recent versions of the Linux kernels and GNU libc contain support for -the System V/Unix98 naming scheme for PTYs, which assigns a common -device {\file /dev/ptmx\/} to all the masters (opening it will -automatically give you a previously unassigned PTY) and a subdirectory -{\file /dev/pts\/} for the slaves; the slaves are named with decimal -integers ({\file /dev/pts/$\#$\/} in our notation). This removes the -problem of exhausting the namespace and enables the kernel to -automatically create the device nodes for the slaves on demand using -the {\file devpts\/} filesystem. - -\end{document} diff -u --recursive --new-file v2.3.99-pre2/linux/Documentation/devices.txt linux/Documentation/devices.txt --- v2.3.99-pre2/linux/Documentation/devices.txt Fri Jan 7 19:13:21 2000 +++ linux/Documentation/devices.txt Thu Mar 23 23:32:47 2000 @@ -1,7 +1,7 @@ LINUX ALLOCATED DEVICES Maintained by H.

Board Compatibility + +This device driver is designed for the DECchip "Tulip", Digital's +single-chip ethernet controllers for PCI. Supported members of the family +are the 21040, 21041, 21140, 21140A, 21142, and 21143. Similar work-alike +chips from Lite-On, Macronics, ASIX, Compex and other listed below are also +supported. + +These chips are used on at least 140 unique PCI board designs. The great +number of chips and board designs supported is the reason for the +driver size and complexity. Almost of the increasing complexity is in the +board configuration and media selection code. There is very little +increasing in the operational critical path length. + +II. Board-specific settings + +PCI bus devices are configured by the system at boot time, so no jumpers +need to be set on the board. The system BIOS preferably should assign the +PCI INTA signal to an otherwise unused system IRQ line. + +Some boards have EEPROMs tables with default media entry. The factory default +is usually "autoselect". This should only be overridden when using +transceiver connections without link beat e.g. 10base2 or AUI, or (rarely!) +for forcing full-duplex when used with old link partners that do not do +autonegotiation. + +III. Driver operation + +IIIa. Ring buffers + +The Tulip can use either ring buffers or lists of Tx and Rx descriptors. +This driver uses statically allocated rings of Rx and Tx descriptors, set at +compile time by RX/TX_RING_SIZE. This version of the driver allocates skbuffs +for the Rx ring buffers at open() time and passes the skb->data field to the +Tulip as receive data buffers. When an incoming frame is less than +RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is +copied to the new skbuff. When the incoming frame is larger, the skbuff is +passed directly up the protocol stack and replaced by a newly allocated +skbuff. + +The RX_COPYBREAK value is chosen to trade-off the memory wasted by +using a full-sized skbuff for small frames vs. the copying costs of larger +frames. For small frames the copying cost is negligible (esp. considering +that we are pre-loading the cache with immediately useful header +information). For large frames the copying cost is non-trivial, and the +larger copy might flush the cache of useful data. A subtle aspect of this +choice is that the Tulip only receives into longword aligned buffers, thus +the IP header at offset 14 isn't longword aligned for further processing. +Copied frames are put into the new skbuff at an offset of "+2", thus copying +has the beneficial effect of aligning the IP header and preloading the +cache. + +IIIC. Synchronization +The driver runs as two independent, single-threaded flows of control. One +is the send-packet routine, which enforces single-threaded use by the +dev->tbusy flag. The other thread is the interrupt handler, which is single +threaded by the hardware and other software. + +The send packet thread has partial control over the Tx ring and 'dev->tbusy' +flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next +queue slot is empty, it clears the tbusy flag when finished otherwise it sets +the 'tp->tx_full' flag. + +The interrupt handler has exclusive control over the Rx ring and records stats +from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so +we can't avoid the interrupt overhead by having the Tx routine reap the Tx +stats.) After reaping the stats, it marks the queue entry as empty by setting +the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the +tx_full and tbusy flags. + +IV.

The wiring is: + * PC0/RxD0 <- rxd (DB9 pin 2) PC4 <- dsr pin 6 + * PC1/TxD0 -> txd pin 3 PC5 <- ri pin 9 + * PC2 -> rts pin 7 PC6 <- dcd pin 1 + * PC3 <- cts pin 8 PC7 -> dtr pin 4 + * PB1 -> line driver standby + * + * The EzUSB register constants below come from their excellent documentation + * and sample code (which used to be available at www.anchorchips.com, but + * that has now been absorbed into Cypress' site and the CD-ROM contents + * don't appear to be available online anymore). If we get multiple + * EzUSB-based drivers into the kernel, it might be useful to pull them out + * into a separate .h file. + * + * THEORY OF OPERATION: + * + * There are two 256-byte ring buffers, one for tx, one for rx. + * + * EP2out is pure tx data. When it appears, the data is copied into the tx + * ring and serial transmission is started if it wasn't already running. The + * "tx buffer empty" interrupt may kick off another character if the ring + * still has data. If the host is tx-blocked because the ring filled up, + * it will request a "tx unthrottle" interrupt. If sending a serial character + * empties the ring below the desired threshold, we set a bit that will send + * up the tx unthrottle message as soon as the rx buffer becomes free. + * + * EP2in (interrupt) is used to send both rx chars and rx status messages + * (only "tx unthrottle" at this time) back up to the host. The first byte + * of the rx message indicates data (0) or status msg (1). Status messages + * are sent before any data. + * + * Incoming serial characters are put into the rx ring by the serial + * interrupt, and the EP2in buffer sent if it wasn't already in transit. + * When the EP2in buffer returns, the interrupt prompts us to send more + * rx chars (or status messages) if they are pending. + * + * Device control happens through "vendor specific" control messages on EP0. + * All messages are destined for the "Interface" (with the index always 0, + * so that if their two-port device might someday use similar firmware, we + * can use index=1 to refer to the second port). The messages defined are: + * + * bRequest = 0 : set baud/bits/parity + * 1 : unused + * 2 : reserved for setting HW flow control (CTSRTS) + * 3 : get/set "modem info" (pin states: DTR, RTS, DCD, RI, etc) + * 4 : set break (on/off) + * 5 : reserved for requesting interrupts on pin state change + * 6 : query buffer room or chars in tx buffer + * 7 : request tx unthrottle interrupt + * + * The host-side driver is set to recognize the device ID values stashed in + * serial EEPROM (0x06cd, 0x0103), program this firmware into place, then + * start it running. This firmware will use EzUSB's "renumeration" trick by + * simulating a bus disconnect, then reconnect with a different device ID + * (encoded in the desc_device descriptor below). The host driver then + * recognizes the new device ID and glues it to the real serial driver code. + * + * USEFUL DOCS: + * EzUSB Technical Reference Manual: + * 8051 manuals: everywhere, but try www.dalsemi.com because the EzUSB is + * basically the Dallas enhanced 8051 code. Remember that the EzUSB IO ports + * use totally different registers! + * USB 1.1 spec: www.usb.org + * + * HOW TO BUILD: + * gcc -x assembler-with-cpp -P -E -o keyspan_pda.asm keyspan_pda.s + * as31 -l keyspan_pda.asm + * mv keyspan_pda.obj keyspan_pda.hex + * perl ezusb_convert.pl keyspan_pda < keyspan_pda.hex > keyspan_pda_fw.h + * Get as31 from , and hack on it + * a bit to make it build. + * + * THANKS: + * Greg Kroah-Hartman, for coordinating the whole usb-serial thing. + * AnchorChips, for making such an incredibly useful little microcontroller. + * KeySpan, for making a handy, cheap ($40) widget that was so easy to take + * apart and trace with an ohmmeter. + * + * TODO: + * lots. grep for TODO.
