Attributes are available via sysfs and uevent +interfaces. + +Each attribute has well defined meaning, up to unit of measure used. While +the attributes provided are believed to be universally applicable to any +power supply, specific monitoring hardware may not be able to provide them +all, so any of them may be skipped. + +Power supply class is extensible, and allows to define drivers own attributes. +The core attribute set is subject to the standard Linux evolution (i.e. +if it will be found that some attribute is applicable to many power supply +types or their drivers, it can be added to the core set). + +It also integrates with LED framework, for the purpose of providing +typically expected feedback of battery charging/fully charged status and +AC/USB power supply online status. (Note that specific details of the +indication (including whether to use it at all) are fully controllable by +user and/or specific machine defaults, per design principles of LED +framework). + + +Attributes/properties +~~~~~~~~~~~~~~~~~~~~~ +Power supply class has predefined set of attributes, this eliminates code +duplication across drivers. Power supply class insist on reusing its +predefined attributes *and* their units. + +So, userspace gets predictable set of attributes and their units for any +kind of power supply, and can process/present them to a user in consistent +manner. Results for different power supplies and machines are also directly +comparable. + +See drivers/power/ds2760_battery.c and drivers/power/pda_power.c for the +example how to declare and handle attributes. + + +Units +~~~~~ +Quoting include/linux/power_supply.h: + + All voltages, currents, charges, energies, time and temperatures in µV, + µA, µAh, µWh, seconds and tenths of degree Celsius unless otherwise + stated. It's driver's job to convert its raw values to units in which + this class operates. + + +Attributes/properties detailed +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +~ ~ ~ ~ ~ ~ ~ Charge/Energy/Capacity - how to not confuse ~ ~ ~ ~ ~ ~ ~ +~ ~ +~ Because both "charge" (µAh) and "energy" (µWh) represents "capacity" ~ +~ of battery, this class distinguish these terms. Don't mix them! ~ +~ ~ +~ CHARGE_* attributes represents capacity in µAh only. ~ +~ ENERGY_* attributes represents capacity in µWh only. ~ +~ CAPACITY attribute represents capacity in *percents*, from 0 to 100. ~ +~ ~ +~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ + +Postfixes: +_AVG - *hardware* averaged value, use it if your hardware is really able to +report averaged values. +_NOW - momentary/instantaneous values. + +STATUS - this attribute represents operating status (charging, full, +discharging (i.e. powering a load), etc.). This corresponds to +BATTERY_STATUS_* values, as defined in battery.h. + +HEALTH - represents health of the battery, values corresponds to +POWER_SUPPLY_HEALTH_*, defined in battery.h. + +VOLTAGE_MAX_DESIGN, VOLTAGE_MIN_DESIGN - design values for maximal and +minimal power supply voltages. Maximal/minimal means values of voltages +when battery considered "full"/"empty" at normal conditions. Yes, there is +no direct relation between voltage and battery capacity, but some dumb +batteries use voltage for very approximated calculation of capacity. +Battery driver also can use this attribute just to inform userspace +about maximal and minimal voltage thresholds of a given battery. + +CHARGE_FULL_DESIGN, CHARGE_EMPTY_DESIGN - design charge values, when +battery considered full/empty. + +ENERGY_FULL_DESIGN, ENERGY_EMPTY_DESIGN - same as above but for energy. + +CHARGE_FULL, CHARGE_EMPTY - These attributes means "last remembered value +of charge when battery became full/empty". It also could mean "value of +charge when battery considered full/empty at given conditions (temperature, +age)". I.e. these attributes represents real thresholds, not design values. + +ENERGY_FULL, ENERGY_EMPTY - same as above but for energy. + +CAPACITY - capacity in percents. +CAPACITY_LEVEL - capacity level. This corresponds to +POWER_SUPPLY_CAPACITY_LEVEL_*. + +TEMP - temperature of the power supply. +TEMP_AMBIENT - ambient temperature. + +TIME_TO_EMPTY - seconds left for battery to be considered empty (i.e. +while battery powers a load) +TIME_TO_FULL - seconds left for battery to be considered full (i.e. +while battery is charging) + + +Battery <-> external power supply interaction +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Often power supplies are acting as supplies and supplicants at the same +time. Batteries are good example. So, batteries usually care if they're +externally powered or not. + +For that case, power supply class implements notification mechanism for +batteries. + +External power supply (AC) lists supplicants (batteries) names in +"supplied_to" struct member, and each power_supply_changed() call +issued by external power supply will notify supplicants via +external_power_changed callback. + + +QA +~~ +Q: Where is POWER_SUPPLY_PROP_XYZ attribute? +A: If you cannot find attribute suitable for your driver needs, feel free + to add it and send patch along with your driver. + + The attributes available currently are the ones currently provided by the + drivers written. + + Good candidates to add in future: model/part#, cycle_time, manufacturer, + etc. + + +Q: I have some very specific attribute (e.g. battery color), should I add + this attribute to standard ones? +A: Most likely, no. Such attribute can be placed in the driver itself, if + it is useful. Of course, if the attribute in question applicable to + large set of batteries, provided by many drivers, and/or comes from + some general battery specification/standard, it may be a candidate to + be added to the core attribute set. + + +Q: Suppose, my battery monitoring chip/firmware does not provides capacity + in percents, but provides charge_{now,full,empty}. Should I calculate + percentage capacity manually, inside the driver, and register CAPACITY + attribute? The same question about time_to_empty/time_to_full. +A: Most likely, no. This class is designed to export properties which are + directly measurable by the specific hardware available. + + Inferring not available properties using some heuristics or mathematical + model is not subject of work for a battery driver. Such functionality + should be factored out, and in fact, apm_power, the driver to serve + legacy APM API on top of power supply class, uses a simple heuristic of + approximating remaining battery capacity based on its charge, current, + voltage and so on. But full-fledged battery model is likely not subject + for kernel at all, as it would require floating point calculation to deal + with things like differential equations and Kalman filters. This is + better be handled by batteryd/libbattery, yet to be written. diff --git a/MAINTAINERS b/MAINTAINERS index 0223d6d191df..151f4ef978a4 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -1856,7 +1856,7 @@ W: http://www.openib.org/ T: git kernel.org:/pub/scm/linux/kernel/git/roland/infiniband.git S: Supported -INPUT (KEYBOARD, MOUSE, JOYSTICK) DRIVERS +INPUT (KEYBOARD, MOUSE, JOYSTICK, TOUCHSCREEN) DRIVERS P: Dmitry Torokhov M: dmitry.torokhov@gmail.com M: dtor@mail.ru diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig index 73455389257a..a00fabe2e4e0 100644 --- a/arch/mips/Kconfig +++ b/arch/mips/Kconfig @@ -15,6 +15,29 @@ choice prompt "System type" default SGI_IP22 +config LEMOTE_FULONG + bool "Lemote Fulong mini-PC" + select ARCH_SPARSEMEM_ENABLE + select SYS_HAS_CPU_LOONGSON2 + select DMA_NONCOHERENT + select BOOT_ELF32 + select BOARD_SCACHE + select HAVE_STD_PC_SERIAL_PORT + select HW_HAS_PCI + select I8259 + select ISA + select IRQ_CPU + select SYS_SUPPORTS_32BIT_KERNEL + select SYS_SUPPORTS_64BIT_KERNEL + select SYS_SUPPORTS_LITTLE_ENDIAN + select SYS_SUPPORTS_HIGHMEM + select SYS_HAS_EARLY_PRINTK + select GENERIC_HARDIRQS_NO__DO_IRQ + select CPU_HAS_WB + help + Lemote Fulong mini-PC board based on the Chinese Loongson-2E CPU and + an FPGA northbridge + config MACH_ALCHEMY bool "Alchemy processor based machines" @@ -63,7 +86,7 @@ config MACH_DECSTATION bool "DECstations" select BOOT_ELF32 select DMA_NONCOHERENT - select SYS_HAS_EARLY_PRINTK + select NO_IOPORT select IRQ_CPU select SYS_HAS_CPU_R3000 select SYS_HAS_CPU_R4X00 @@ -88,24 +111,6 @@ config MACH_DECSTATION otherwise choose R3000. -config MIPS_EV64120 - bool "Galileo EV64120 Evaluation board (EXPERIMENTAL)" - depends on EXPERIMENTAL - select DMA_NONCOHERENT - select HW_HAS_PCI - select PCI_GT64XXX_PCI0 - select SYS_HAS_CPU_R5000 - select SYS_SUPPORTS_32BIT_KERNEL - select SYS_SUPPORTS_64BIT_KERNEL - select SYS_SUPPORTS_BIG_ENDIAN - select SYS_SUPPORTS_KGDB - help - This is an evaluation board based on the Galileo GT-64120 - single-chip system controller that contains a MIPS R5000 compatible - core running at 75/100MHz.

I use busy wait instead of timer wait in STEN_LOW,DTEN_LOW - thus driver causes CPU overhead and is very slow - 2. could not find a way to stop the drive, when it is - in data read mode, therefore I had to set - msf.end.min/sec/frame to 0:0:1 (in azt_poll); so only one - frame can be read in sequence, this is also the reason for - 3. getting 'timeout in state 4' messages, but nevertheless - it works - W.Zimmermann, Oct. 31, 1994 - V0.1 Version is ALPHA, problems #2 and #3 resolved. - W.Zimmermann, Nov. 3, 1994 - V0.2 Modification to some comments, debugging aids for partial test - with Borland C under DOS eliminated. Timer interrupt wait - STEN_LOW_WAIT additionally to busy wait for STEN_LOW implemented; - use it only for the 'slow' commands (ACMD_GET_Q_CHANNEL, ACMD_ - SEEK_TO_LEAD_IN), all other commands are so 'fast', that busy - waiting seems better to me than interrupt rescheduling. - Besides that, when used in the wrong place, STEN_LOW_WAIT causes - kernel panic. - In function aztPlay command ACMD_PLAY_AUDIO added, should make - audio functions work. The Aztech drive needs different commands - to read data tracks and play audio tracks. - W.Zimmermann, Nov. 8, 1994 - V0.3 Recognition of missing drive during boot up improved (speeded up). - W.Zimmermann, Nov. 13, 1994 - V0.35 Rewrote the control mechanism in azt_poll (formerly mcd_poll) - including removal of all 'goto' commands. :-); - J. Nardone, Nov. 14, 1994 - V0.4 Renamed variables and constants to 'azt' instead of 'mcd'; had - to make some "compatibility" defines in azt.h; please note, - that the source file was renamed to azt.c, the include file to - azt.h - Speeded up drive recognition during init (will be a little bit - slower than before if no drive is installed!); suggested by - Robby Schirmer. - read_count declared volatile and set to AZT_BUF_SIZ to make - drive faster (now 300kB/sec, was 60kB/sec before, measured - by 'time dd if=/dev/cdrom of=/dev/null bs=2048 count=4096'; - different AZT_BUF_SIZes were test, above 16 no further im- - provement seems to be possible; suggested by E.Moenkeberg. - W.Zimmermann, Nov. 18, 1994 - V0.42 Included getAztStatus command in GetQChannelInfo() to allow - reading Q-channel info on audio disks, if drive is stopped, - and some other bug fixes in the audio stuff, suggested by - Robby Schirmer. - Added more ioctls (reading data in mode 1 and mode 2). - Completely removed the old azt_poll() routine. - Detection of ORCHID CDS-3110 in aztcd_init implemented. - Additional debugging aids (see the readme file). - W.Zimmermann, Dec. 9, 1994 - V0.50 Autodetection of drives implemented. - W.Zimmermann, Dec. 12, 1994 - V0.52 Prepared for including in the standard kernel, renamed most - variables to contain 'azt', included autoconf.h - W.Zimmermann, Dec. 16, 1994 - V0.6 Version for being included in the standard Linux kernel. - Renamed source and header file to aztcd.c and aztcd.h - W.Zimmermann, Dec. 24, 1994 - V0.7 Changed VERIFY_READ to VERIFY_WRITE in aztcd_ioctl, case - CDROMREADMODE1 and CDROMREADMODE2; bug fix in the ioctl, - which causes kernel crashes when playing audio, changed - include-files (config.h instead of autoconf.h, removed - delay.h) - W.Zimmermann, Jan. 8, 1995 - V0.72 Some more modifications for adaption to the standard kernel. - W.Zimmermann, Jan. 16, 1995 - V0.80 aztcd is now part of the standard kernel since version 1.1.83. - Modified the SET_TIMER and CLEAR_TIMER macros to comply with - the new timer scheme. - W.Zimmermann, Jan. 21, 1995 - V0.90 Included CDROMVOLCTRL, but with my Aztech drive I can only turn - the channels on and off. If it works better with your drive, - please mail me. Also implemented ACMD_CLOSE for CDROMSTART. - W.Zimmermann, Jan. 24, 1995 - V1.00 Implemented close and lock tray commands. Patches supplied by - Frank Racis - Added support for loadable MODULEs, so aztcd can now also be - loaded by insmod and removed by rmmod during run time - Werner Zimmermann, Mar. 24, 95 - V1.10 Implemented soundcard configuration for Orchid CDS-3110 drives - connected to Soundwave32 cards. Release for LST 2.1. - (still experimental) - Werner Zimmermann, May 8, 95 - V1.20 Implemented limited support for DOSEMU0.60's cdrom.c. Now it works, but - sometimes DOSEMU may hang for 30 seconds or so. A fully functional ver- - sion needs an update of Dosemu0.60's cdrom.c, which will come with the - next revision of Dosemu. - Also Soundwave32 support now works. - Werner Zimmermann, May 22, 95 - V1.30 Auto-eject feature. Inspired by Franc Racis (racis@psu.edu) - Werner Zimmermann, July 4, 95 - V1.40 Started multisession support. Implementation copied from mcdx.c - by Heiko Schlittermann. Not tested yet. - Werner Zimmermann, July 15, 95 - V1.50 Implementation of ioctl CDROMRESET, continued multisession, began - XA, but still untested. Heavy modifications to drive status de- - tection. - Werner Zimmermann, July 25, 95 - V1.60 XA support now should work. Speeded up drive recognition in cases, - where no drive is installed. - Werner Zimmermann, August 8, 1995 - V1.70 Multisession support now is completed, but there is still not - enough testing done. If you can test it, please contact me. For - details please read Documentation/cdrom/aztcd - Werner Zimmermann, August 19, 1995 - V1.80 Modification to suit the new kernel boot procedure introduced - with kernel 1.3.33.

Use of interrupts is highly encouraged, it - * cuts CPU usage down to a reasonable level. I had DMA in for a while - * but PC DMA is just too slow. Better to just insb() it. - * - * One thing about these drives: They talk in MSF (Minute Second Frame) format. - * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a - * disk. The funny thing is that these are sent to the drive in BCD, but the - * interface wants to see them in decimal. A lot of conversion goes on. - * - * DRIVER SPECIAL FEATURES - * ----------------------- - * - * This section describes features beyond the normal audio and CD-ROM - * functions of the drive. - * - * XA compatibility - * - * The driver should support XA disks for both the CDU31A and CDU33A. - * It does this transparently, the using program doesn't need to set it. - * - * Multi-Session - * - * A multi-session disk looks just like a normal disk to the user. - * Just mount one normally, and all the data should be there. - * A special thanks to Koen for help with this! - * - * Raw sector I/O - * - * Using the CDROMREADAUDIO it is possible to read raw audio and data - * tracks. Both operations return 2352 bytes per sector. On the data - * tracks, the first 12 bytes is not returned by the drive and the value - * of that data is indeterminate. - * - * - * Copyright (C) 1993 Corey Minyard - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Note that there is a small problem - * still here, if the eject button is pushed while the - * drive light is flashing, the drive will return a bad - * status and be reset. It recovers, though. - * - * 03/07/97 - Fixed a problem with timers. - * - * - * 18 Spetember 1997 -- Ported to Uniform CD-ROM driver by - * Heiko Eissfeldt <heiko@colossus.escape.de> with additional - * changes by Erik Andersen <andersee@debian.org> - * - * 24 January 1998 -- Removed the scd_disc_status() function, which was now - * just dead code left over from the port. - * Erik Andersen <andersee@debian.org> - * - * 16 July 1998 -- Drive donated to Erik Andersen by John Kodis - * <kodis@jagunet.com>. Work begun on fixing driver to - * work under 2.1.X. Added temporary extra printks - * which seem to slow it down enough to work. - * - * 9 November 1999 -- Make kernel-parameter implementation work with 2.3.x - * Removed init_module & cleanup_module in favor of - * module_init & module_exit. - * Torben Mathiasen <tmm@image.dk> - * - * 22 October 2004 -- Make the driver work in 2.6.X - * Added workaround to fix hard lockups on eject - * Fixed door locking problem after mounting empty drive - * Set double-speed drives to double speed by default - * Removed all readahead things - not needed anymore - * Ondrej Zary <rainbow@rainbow-software.org> -*/ - -#define DEBUG 1 - -#include <linux/major.h> -#include <linux/module.h> -#include <linux/errno.h> -#include <linux/signal.h> -#include <linux/sched.h> -#include <linux/timer.h> -#include <linux/fs.h> -#include <linux/kernel.h> -#include <linux/hdreg.h> -#include <linux/genhd.h> -#include <linux/ioport.h> -#include <linux/string.h> -#include <linux/slab.h> -#include <linux/init.h> -#include <linux/interrupt.h> -#include <linux/cdrom.h> - -#include <asm/system.h> -#include <asm/io.h> -#include <asm/uaccess.h> -#include <asm/dma.h> - -#include "cdu31a.h" - -#define MAJOR_NR CDU31A_CDROM_MAJOR -#include <linux/blkdev.h> - -#define CDU31A_MAX_CONSECUTIVE_ATTENTIONS 10 - -#define PFX "CDU31A: " - -/* -** Edit the following data to change interrupts, DMA channels, etc. -** Default is polled and no DMA.

Waiting for documentation... - 22 feb 1995: 0.1a first reasonably safe polling driver. - Two major bugs, one in read_sector and one in - do_cm206_request, happened to cancel! - 25 feb 1995: 0.2a first reasonable interrupt driven version of above. - uart writes are still done in polling mode. - 25 feb 1995: 0.21a writes also in interrupt mode, still some - small bugs to be found... Larger buffer. - 2 mrt 1995: 0.22 Bug found (cd-> nowhere, interrupt was called in - initialization), read_ahead of 16. Timeouts implemented. - unclear if they do something... - 7 mrt 1995: 0.23 Start of background read-ahead. - 18 mrt 1995: 0.24 Working background read-ahead. (still problems) - 26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2). - Statistics implemented, though separate stats206.h. - Accessible through ioctl 0x1000 (just a number). - Hard to choose between v1.2 development and 1.1.75. - Bottom-half doesn't work with 1.2... - 0.25a: fixed... typo. Still problems... - 1 apr 1995: 0.26 Module support added. Most bugs found. Use kernel 1.2.n. - 5 apr 1995: 0.27 Auto-probe for the adapter card base address. - Auto-probe for the adaptor card irq line. - 7 apr 1995: 0.28 Added lilo setup support for base address and irq. - Use major number 32 (not in this source), officially - assigned to this driver. - 9 apr 1995: 0.29 Added very limited audio support. Toc_header, stop, pause, - resume, eject. Play_track ignores track info, because we can't - read a table-of-contents entry. Toc_entry is implemented - as a `placebo' function: always returns start of disc. - 3 may 1995: 0.30 Audio support completed. The get_toc_entry function - is implemented as a binary search. - 15 may 1995: 0.31 More work on audio stuff. Workman is not easy to - satisfy; changed binary search into linear search. - Auto-probe for base address somewhat relaxed. - 1 jun 1995: 0.32 Removed probe_irq_on/off for module version. - 10 jun 1995: 0.33 Workman still behaves funny, but you should be - able to eject and substitute another disc. - - An adaptation of 0.33 is included in linux-1.3.7 by Eberhard Moenkeberg - - 18 jul 1995: 0.34 Patch by Heiko Eissfeldt included, mainly considering - verify_area's in the ioctls. Some bugs introduced by - EM considering the base port and irq fixed. - - 18 dec 1995: 0.35 Add some code for error checking... no luck... - - We jump to reach our goal: version 1.0 in the next stable linux kernel. - - 19 mar 1996: 0.95 Different implementation of CDROM_GET_UPC, on - request of Thomas Quinot. - 25 mar 1996: 0.96 Interpretation of opening with O_WRONLY or O_RDWR: - open only for ioctl operation, e.g., for operation of - tray etc. - 4 apr 1996: 0.97 First implementation of layer between VFS and cdrom - driver, a generic interface. Much of the functionality - of cm206_open() and cm206_ioctl() is transferred to a - new file cdrom.c and its header ucdrom.h. - - Upgrade to Linux kernel 1.3.78. - - 11 apr 1996 0.98 Upgrade to Linux kernel 1.3.85 - More code moved to cdrom.c - - 0.99 Some more small changes to decrease number - of oopses at module load; - - 27 jul 1996 0.100 Many hours of debugging, kernel change from 1.2.13 - to 2.0.7 seems to have introduced some weird behavior - in (interruptible_)sleep_on(&cd->data): the process - seems to be woken without any explicit wake_up in my own - code. Patch to try 100x in case such untriggered wake_up's - occur. - - 28 jul 1996 0.101 Rewriting of the code that receives the command echo, - using a fifo to store echoed bytes. - - Branch from 0.99: - - 0.99.1.0 Update to kernel release 2.0.10 dev_t -> kdev_t - (emoenke) various typos found by others. extra - module-load oops protection. - - 0.99.1.1 Initialization constant cdrom_dops.speed - changed from float (2.0) to int (2); Cli()-sti() pair - around cm260_reset() in module initialization code. - - 0.99.1.2 Changes literally as proposed by Scott Snyder - <snyder@d0sgif.fnal.gov> for the 2.1 kernel line, which - have to do mainly with the poor minor support i had. The - major new concept is to change a cdrom driver's - operations struct from the capabilities struct. This - reflects the fact that there is one major for a driver, - whilst there can be many minors whith completely - different capabilities. - - 0.99.1.3 More changes for operations/info separation. - - 0.99.1.4 Added speed selection (someone had to do this - first). - - 23 jan 1997 0.99.1.5 MODULE_PARMS call added. - - 23 jan 1997 0.100.1.2--0.100.1.5 following similar lines as - 0.99.1.1--0.99.1.5. I get too many complaints about the - drive making read errors. What't wrong with the 2.0+ - kernel line? Why get i (and othe cm206 owners) weird - results? Why were things good in the good old 1.1--1.2 - era? Why don't i throw away the drive? - - 2 feb 1997 0.102 Added `volatile' to values in cm206_struct. Seems to - reduce many of the problems. Rewrote polling routines - to use fixed delays between polls. - 0.103 Changed printk behavior. - 0.104 Added a 0.100 -> 0.100.1.1 change - -11 feb 1997 0.105 Allow auto_probe during module load, disable - with module option "auto_probe=0". Moved some debugging - statements to lower priority. Implemented select_speed() - function. - -13 feb 1997 1.0 Final version for 2.0 kernel line. - - All following changes will be for the 2.1 kernel line. - -15 feb 1997 1.1 Keep up with kernel 2.1.26, merge in changes from - cdrom.c 0.100.1.1--1.0. Add some more MODULE_PARMS. - -14 sep 1997 1.2 Upgrade to Linux 2.1.55. Added blksize_size[], patch - sent by James Bottomley <James.Bottomley@columbiasc.ncr.com>. - -21 dec 1997 1.4 Upgrade to Linux 2.1.72. - -24 jan 1998 Removed the cm206_disc_status() function, as it was now dead - code. The Uniform CDROM driver now provides this functionality. - -9 Nov. 1999 Make kernel-parameter implementation work with 2.3.x - Removed init_module & cleanup_module in favor of - module_init & module_exit. - Torben Mathiasen <tmm@image.dk> - * - * Parts of the code are based upon lmscd.c written by Kai Petzke, - * sbpcd.c written by Eberhard Moenkeberg, and mcd.c by Martin - * Harriss, but any off-the-shelf dynamic programming algorithm won't - * be able to find them. - * - * The cm206 drive interface and the cm260 adapter card seem to be - * sufficiently different from their cm205/cm250 counterparts - * in order to write a complete new driver. - * - * I call all routines connected to the Linux kernel something - * with `cm206' in it, as this stuff is too series-dependent. - * - * Currently, my limited knowledge is based on: - * - The Linux Kernel Hacker's guide, v. 0.5, by Michael K.

Speed is around 240 kb/s, as measured - with "time dd if=/dev/cdrom of=/dev/null \ - bs=2048 count=4096". - 24-6-95 v0.2 Reworked the #defines for the command codes - and the like, as well as the structure of - the hardware communication protocol, to - reflect the "official" documentation, kindly - supplied by C.K. Tan, Optics Storage Pte. Ltd. - Also tidied up the state machine somewhat. - 28-6-95 v0.3 Removed the ISP-16 interface code, as this - should go into its own driver. The driver now - has its own major nr. - Disk change detection now seems to work, too. - This version became part of the standard - kernel as of version 1.3.7 - 24-9-95 v0.4 Re-inserted ISP-16 interface code which I - copied from sjcd.c, with a few changes. - Updated README.optcd. Submitted for - inclusion in 1.3.21 - 29-9-95 v0.4a Fixed bug that prevented compilation as module - 25-10-95 v0.5 Started multisession code. Implementation - copied from Werner Zimmermann, who copied it - from Heiko Schlittermann's mcdx. - 17-1-96 v0.6 Multisession works; some cleanup too. - 18-4-96 v0.7 Increased some timing constants; - thanks to Luke McFarlane. Also tidied up some - printk behaviour. ISP16 initialization - is now handled by a separate driver. - - 09-11-99 Make kernel-parameter implementation work with 2.3.x - Removed init_module & cleanup_module in favor of - module_init & module_exit. - Torben Mathiasen <tmm@image.dk> -*/ - -/* Includes */ - - -#include <linux/module.h> -#include <linux/mm.h> -#include <linux/ioport.h> -#include <linux/init.h> - -#include <asm/io.h> -#include <linux/blkdev.h> - -#include <linux/cdrom.h> -#include "optcd.h" - -#include <asm/uaccess.h> - -#define MAJOR_NR OPTICS_CDROM_MAJOR -#define QUEUE (opt_queue) -#define CURRENT elv_next_request(opt_queue) - - -/* Debug support */ - - -/* Don't forget to add new debug flags here. */ -#if DEBUG_DRIVE_IF | DEBUG_VFS | DEBUG_CONV | DEBUG_TOC | \ - DEBUG_BUFFERS | DEBUG_REQUEST | DEBUG_STATE | DEBUG_MULTIS -#define DEBUG(x) debug x -static void debug(int debug_this, const char* fmt, ...) -{ - char s[1024];

That gives the message - * "ResponseStatus timed out" (happens about 6 times here during - * a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is - * handled without data error, but it should get done better. - * - * 0.5 Free CPU during waits (again with help from Kai Makisara). - * Made it work together with the LILO/kernel setup standard. - * Included auto-probing code, as suggested by YGGDRASIL. - * Formal redesign to add DDI debugging. - * There are still flaws in IOCTL (workman with double speed drive). - * - * 1.0 Added support for all drive IDs (0...3, no longer only 0) - * and up to 4 drives on one controller. - * Added "#define MANY_SESSION" for "old" multi session CDs. - * - * 1.1 Do SpinUp for new drives, too. - * Revised for clean compile under "old" kernels (0.99pl9). - * - * 1.2 Found the "workman with double-speed drive" bug: use the driver's - * audio_state, not what the drive is reporting with ReadSubQ. - * - * 1.3 Minor cleanups. - * Refinements regarding Workman. - * - * 1.4 Read XA disks (PhotoCDs) with "old" drives, too (but only the first - * session - no chance to fully access a "multi-session" CD). - * This currently still is too slow (50 kB/sec) - but possibly - * the old drives won't do it faster. - * Implemented "door (un)lock" for new drives (still does not work - * as wanted - no lock possible after an unlock). - * Added some debugging printout for the UPC/EAN code - but my drives - * return only zeroes. Is there no UPC/EAN code written? - * - * 1.5 Laborate with UPC/EAN code (not better yet). - * Adapt to kernel 1.1.8 change (have to explicitly include - * <linux/string.h> now). - * - * 1.6 Trying to read audio frames as data. Impossible with the current - * drive firmware levels, as it seems. Awaiting any hint. ;-) - * Changed "door unlock": repeat it until success. - * Changed CDROMSTOP routine (stop somewhat "softer" so that Workman - * won't get confused). - * Added a third interface type: Sequoia S-1000, as used with the SPEA - * Media FX sound card. This interface (usable for Sony and Mitsumi - * drives, too) needs a special configuration setup and behaves like a - * LaserMate type after that. Still experimental - I do not have such - * an interface. - * Use the "variable BLOCK_SIZE" feature (2048). But it does only work - * if you give the mount option "block=2048". - * The media_check routine is currently disabled; now that it gets - * called as it should I fear it must get synchronized for not to - * disturb the normal driver's activity. - * - * 2.0 Version number bumped - two reasons: - * - reading audio tracks as data works now with CR-562 and CR-563. We - * currently do it by an IOCTL (yet has to get standardized), one frame - * at a time; that is pretty slow. But it works. - * - we are maintaining now up to 4 interfaces (each up to 4 drives): - * did it the easy way - a different MAJOR (25, 26, ...) and a different - * copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only - * distinguished by the value of SBPCD_ISSUE and the driver's name), - * and a common sbpcd.h file. - * Bettered the "ReadCapacity error" problem with old CR-52x drives (the - * drives sometimes need a manual "eject/insert" before work): just - * reset the drive and do again. Needs lots of resets here and sometimes - * that does not cure, so this can't be the solution. - * - * 2.1 Found bug with multisession CDs (accessing frame 16). - * "read audio" works now with address type CDROM_MSF, too. - * Bigger audio frame buffer: allows reading max. 4 frames at time; this - * gives a significant speedup, but reading more than one frame at once - * gives missing chunks at each single frame boundary. - * - * 2.2 Kernel interface cleanups: timers, init, setup, media check. - * - * 2.3 Let "door lock" and "eject" live together. - * Implemented "close tray" (done automatically during open). - * - * 2.4 Use different names for device registering. - * - * 2.5 Added "#if EJECT" code (default: enabled) to automatically eject - * the tray during last call to "sbpcd_release". - * Added "#if JUKEBOX" code (default: disabled) to automatically eject - * the tray during call to "sbpcd_open" if no disk is in. - * Turn on the CD volume of "compatible" sound cards, too; just define - * SOUND_BASE (in sbpcd.h) accordingly (default: disabled). - * - * 2.6 Nothing new. - * - * 2.7 Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly: - * 0 disables, 1 enables auto-ejecting. Useful to keep the tray in - * during shutdown. - * - * 2.8 Added first support (still BETA, I need feedback or a drive) for - * the Longshine LCS-7260 drives. They appear as double-speed drives - * using the "old" command scheme, extended by tray control and door - * lock functions. - * Found (and fixed preliminary) a flaw with some multisession CDs: we - * have to re-direct not only the accesses to frame 16 (the isofs - * routines drive it up to max. 100), but also those to the continuation - * (repetition) frames (as far as they exist - currently set fix as - * 16..20). - * Changed default of the "JUKEBOX" define. If you use this default, - * your tray will eject if you try to mount without a disk in. Next - * mount command will insert the tray - so, just fill in a disk. ;-) - * - * 2.9 Fulfilled the Longshine LCS-7260 support; with great help and - * experiments by Serge Robyns. - * First attempts to support the TEAC CD-55A drives; but still not - * usable yet. - * Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle - * multi session CDs more "transparent" (redirection handling has to be - * done within the isofs routines, and only for the special purpose of - * obtaining the "right" volume descriptor; accesses to the raw device - * should not get redirected). - * - * 3.0 Just a "normal" increment, with some provisions to do it better. ;-) - * Introduced "#define READ_AUDIO" to specify the maximum number of - * audio frames to grab with one request. This defines a buffer size - * within kernel space; a value of 0 will reserve no such space and - * disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading - * of a whole second with one command, but will use a buffer of more - * than 172 kB. - * Started CD200 support. Drive detection should work, but nothing - * more. - * - * 3.1 Working to support the CD200 and the Teac CD-55A drives. - * AT-BUS style device numbering no longer used: use SCSI style now. - * So, the first "found" device has MINOR 0, regardless of the - * jumpered drive ID. This implies modifications to the /dev/sbpcd* - * entries for some people, but will help the DAU (german TLA, english: - * "newbie", maybe ;-) to install his "first" system from a CD. - * - * 3.2 Still testing with CD200 and CD-55A drives. - * - * 3.3 Working with CD200 support. - * - * 3.4 Auto-probing stops if an address of 0 is seen (to be entered with - * the kernel command line). - * Made the driver "loadable". If used as a module, "audio copy" is - * disabled, and the internal read ahead data buffer has a reduced size - * of 4 kB; so, throughput may be reduced a little bit with slow CPUs. - * - * 3.5 Provisions to handle weird photoCDs which have an interrupted - * "formatting" immediately after the last frames of some files: simply - * never "read ahead" with MultiSession CDs. By this, CPU usage may be - * increased with those CDs, and there may be a loss in speed. - * Re-structured the messaging system. - * The "loadable" version no longer has a limited READ_AUDIO buffer - * size. - * Removed "MANY_SESSION" handling for "old" multi session CDs. - * Added "private" IOCTLs CDROMRESET and CDROMVOLREAD. - * Started again to support the TEAC CD-55A drives, now that I found - * the money for "my own" drive. ;-) - * The TEAC CD-55A support is fairly working now. - * I have measured that the drive "delivers" at 600 kB/sec (even with - * bigger requests than the drive's 64 kB buffer can satisfy), but - * the "real" rate does not exceed 520 kB/sec at the moment. - * Caused by the various changes to build in TEAC support, the timed - * loops are de-optimized at the moment (less throughput with CR-52x - * drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64). - * - * 3.6 Fixed TEAC data read problems with SbPro interfaces. - * Initial size of the READ_AUDIO buffer is 0. Can get set to any size - * during runtime. - * - * 3.7 Introduced MAX_DRIVES for some poor interface cards (seen with TEAC - * drives) which allow only one drive (ID 0); this avoids repetitive - * detection under IDs 1..3. - * Elongated cmd_out_T response waiting; necessary for photo CDs with - * a lot of sessions. - * Bettered the sbpcd_open() behavior with TEAC drives. - * - * 3.8 Elongated max_latency for CR-56x drives. - * - * 3.9 Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface - * configuration bug. - * Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy - * the config_spea() routine into their drivers. ;-) - * - * 4.0 No "big step" - normal version increment. - * Adapted the benefits from 1.3.33. - * Fiddled with CDROMREADAUDIO flaws. - * Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version - * seems not to support it). - * Fulfilled "read audio" for CD200 drives, with help of Pete Heist - * (heistp@rpi.edu). - * - * 4.1 Use loglevel KERN_INFO with printk(). - * Added support for "Vertos 100" drive ("ECS-AT") - it is very similar - * to the Longshine LCS-7260. Give feedback if you can - I never saw - * such a drive, and I have no specs. - * - * 4.2 Support for Teac 16-bit interface cards. Can't get auto-detected, - * so you have to jumper your card to 0x2C0. Still not 100% - come - * in contact if you can give qualified feedback. - * Use loglevel KERN_NOTICE with printk(). If you get annoyed by a - * flood of unwanted messages and the accompanied delay, try to read - * my documentation. Especially the Linux CDROM drivers have to do an - * important job for the newcomers, so the "distributed" version has - * to fit some special needs. Since generations, the flood of messages - * is user-configurable (even at runtime), but to get aware of this, one - * needs a special mental quality: the ability to read. - * - * 4.3 CD200F does not like to receive a command while the drive is - * reading the ToC; still trying to solve it. - * Removed some redundant verify_area calls (yes, Heiko Eissfeldt - * is visiting all the Linux CDROM drivers ;-). - * - * 4.4 Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down" - * experiments: "KLOGD_PAUSE". - * Inhibited "play audio" attempts with data CDs. Provisions for a - * "data-safe" handling of "mixed" (data plus audio) Cds. - * - * 4.5 Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a - * special end_request routine: we seem to have to take care for not - * to have two processes working at the request list. My understanding - * was and is that ll_rw_blk should not call do_sbpcd_request as long - * as there is still one call active (the first call will care for all - * outstanding I/Os, and if a second call happens, that is a bug in - * ll_rw_blk.c). - * "Check media change" without touching any drive. - * - * 4.6 Use a semaphore to synchronize multi-activity; elaborated by Rob - * Riggs <rriggs@tesser.com>.

With this interface, CDROMs can be - * accessed and standard audio CDs can be played back normally. - * - * This interface is (unfortunately) a polled interface. This is - * because most Sony interfaces are set up with DMA and interrupts - * disables. Some (like mine) do not even have the capability to - * handle interrupts or DMA. For this reason you will see a bit of - * the following: - * - * snap = jiffies; - * while (jiffies-snap < SONY_JIFFIES_TIMEOUT) - * { - * if (some_condition()) - * break; - * sony_sleep(); - * } - * if (some_condition not met) - * { - * return an_error; - * } - * - * This ugly hack waits for something to happen, sleeping a little - * between every try. (The conditional is written so that jiffies - * wrap-around is handled properly.) - * - * One thing about these drives: They talk in MSF (Minute Second Frame) format. - * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a - * disk. The funny thing is that these are sent to the drive in BCD, but the - * interface wants to see them in decimal. A lot of conversion goes on. - * - * Copyright (C) 1993 Corey Minyard - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
