Kokshaysky" <ink@jurassic.park.msu.ru> - * Note: joystick address handling might still be wrong on archs - * other than i386 - * 15.06.1999 0.12 Fix bad allocation bug. - * Thanks to Deti Fliegl <fliegl@in.tum.de> - * 28.06.1999 0.13 Add pci_set_master - * 03.08.1999 0.14 adapt to Linus' new __setup/__initcall - * added kernel command line option "es1371=joystickaddr" - * removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge - * 10.08.1999 0.15 (Re)added S/PDIF module option for cards revision >= 4. - * Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>. - * module_init/__setup fixes - * 08.16.1999 0.16 Joe Cotellese <joec@ensoniq.com> - * Added detection for ES1371 revision ID so that we can - * detect the ES1373 and later parts. - * added AC97 #defines for readability - * added a /proc file system for dumping hardware state - * updated SRC and CODEC w/r functions to accommodate bugs - * in some versions of the ES137x chips. - * 31.08.1999 0.17 add spin_lock_init - * replaced current->state = x with set_current_state(x) - * 03.09.1999 0.18 change read semantics for MIDI to match - * OSS more closely; remove possible wakeup race - * 21.10.1999 0.19 Round sampling rates, requested by - * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp> - * 27.10.1999 0.20 Added SigmaTel 3D enhancement string - * Codec ID printing changes - * 28.10.1999 0.21 More waitqueue races fixed - * Joe Cotellese <joec@ensoniq.com> - * Changed PCI detection routine so we can more easily - * detect ES137x chip and derivatives. - * 05.01.2000 0.22 Should now work with rev7 boards; patch by - * Eric Lemar, elemar@cs.washington.edu - * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun; - * Tim Janik's BSE (Bedevilled Sound Engine) found this - * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver - * 07.02.2000 0.25 Use ac97_codec - * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com> - * Use pci_module_init - * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask - * 12.12.2000 0.28 More dma buffer initializations, patch from - * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com> - * 05.01.2001 0.29 Hopefully updates will not be required anymore when Creative bumps - * the CT5880 revision. - * suggested by Stephan Müller <smueller@chronox.de> - * 31.01.2001 0.30 Register/Unregister gameport - * Fix SETTRIGGER non OSS API conformity - * 14.07.2001 0.31 Add list of laptops needing amplifier control - * 03.01.2003 0.32 open_mode fixes from Georg Acher <acher@in.tum.de> - */ - -/*****************************************************************************/ - -#include <linux/interrupt.h> -#include <linux/module.h> -#include <linux/string.h> -#include <linux/ioport.h> -#include <linux/sched.h> -#include <linux/delay.h> -#include <linux/sound.h> -#include <linux/slab.h> -#include <linux/soundcard.h> -#include <linux/pci.h> -#include <linux/init.h> -#include <linux/poll.h> -#include <linux/bitops.h> -#include <linux/proc_fs.h> -#include <linux/spinlock.h> -#include <linux/smp_lock.h> -#include <linux/ac97_codec.h> -#include <linux/gameport.h> -#include <linux/wait.h> -#include <linux/dma-mapping.h> -#include <linux/mutex.h> -#include <linux/mm.h> -#include <linux/kernel.h> -

They are known - * as comm1 and comm2 (communication areas 1 and 2). Comm1 is for - * input, and comm2 is for output. Each is controlled by three - * registers: BASE (base address), CFG (config) and CCTL - * (config/control). - * - * Each DMA channel points to a physically contiguous ring buffer in - * main memory of up to 8 Kbytes. (This driver always uses 8 Kb.) - * There are three pointers into the ring buffer: read, write, and - * trigger. The pointers are 8 bits each. Each pointer points to - * 32-byte "chunks" of data. The DMA engine moves 32 bytes at a time, - * so there is no finer-granularity control. - * - * In comm1, the hardware updates the write ptr, and software updates - * the read ptr. In comm2, it's the opposite: hardware updates the - * read ptr, and software updates the write ptr. I designate the - * hardware-updated ptr as the hwptr, and the software-updated ptr as - * the swptr. - * - * The trigger ptr and trigger mask are used to trigger interrupts. - * From the Lithium spec, section 5.6.8, revision of 12/15/1998: - * - * Trigger Mask Value - * - * A three bit wide field that represents a power of two mask - * that is used whenever the trigger pointer is compared to its - * respective read or write pointer. A value of zero here - * implies a mask of 0xFF and a value of seven implies a mask - * 0x01. This value can be used to sub-divide the ring buffer - * into pie sections so that interrupts monitor the progress of - * hardware from section to section. - * - * My interpretation of that is, whenever the hw ptr is updated, it is - * compared with the trigger ptr, and the result is masked by the - * trigger mask. (Actually, by the complement of the trigger mask.) - * If the result is zero, an interrupt is triggered. I.e., interrupt - * if ((hwptr & ~mask) == (trptr & ~mask)). The mask is formed from - * the trigger register value as mask = (1 << (8 - tmreg)) - 1. - * - * In yet different words, setting tmreg to 0 causes an interrupt after - * every 256 DMA chunks (8192 bytes) or once per traversal of the - * ring buffer.
