IOCTLs and rearranging `psmread', `psmioctl'... 51 * - 14, 30 November 1996. Uses `kbdio.c'. 52 * - 13 December 1996. Uses queuing version of `kbdio.c'. 53 * - January/February 1997. Tweaked probe logic for 54 * HiNote UltraII/Latitude/Armada laptops. 55 * - 30 July 1997. Added APM support. 56 * - 5 March 1997. Defined driver configuration flags (PSM_CONFIG_XXX). 57 * Improved sync check logic. 58 * Vendor specific support routines. 59 */ 60 61#include <sys/cdefs.h> 62__FBSDID("$FreeBSD: head/sys/dev/atkbdc/psm.c 126076 2004-02-21 19:42:58Z phk $"); 63 64#include "opt_psm.h" 65 66#include <sys/param.h> 67#include <sys/systm.h> 68#include <sys/kernel.h> 69#include <sys/module.h> 70#include <sys/bus.h> 71#include <sys/conf.h> 72#include <sys/poll.h> 73#include <sys/syslog.h> 74#include <machine/bus.h> 75#include <sys/rman.h> 76#include <sys/selinfo.h> 77#include <sys/sysctl.h> 78#include <sys/time.h> 79#include <sys/uio.h> 80 81#include <sys/limits.h> 82#include <sys/mouse.h> 83#include <machine/resource.h> 84 85#include <isa/isavar.h> 86#include <dev/kbd/atkbdcreg.h> 87 88/* 89 * Driver specific options: the following options may be set by 90 * `options' statements in the kernel configuration file. 91 */ 92 93/* debugging */ 94#ifndef PSM_DEBUG 95#define PSM_DEBUG 0 /* logging: 0: none, 1: brief, 2: verbose */ 96#endif 97 98#ifndef PSM_SYNCERR_THRESHOLD1 99#define PSM_SYNCERR_THRESHOLD1 20 100#endif 101 102#ifndef PSM_INPUT_TIMEOUT 103#define PSM_INPUT_TIMEOUT 2000000 /* 2 sec */ 104#endif 105 106/* end of driver specific options */ 107 108#define PSM_DRIVER_NAME "psm" 109#define PSMCPNP_DRIVER_NAME "psmcpnp" 110 111/* input queue */ 112#define PSM_BUFSIZE 960 113#define PSM_SMALLBUFSIZE 240 114 115/* operation levels */ 116#define PSM_LEVEL_BASE 0 117#define PSM_LEVEL_STANDARD 1 118#define PSM_LEVEL_NATIVE 2 119#define PSM_LEVEL_MIN PSM_LEVEL_BASE 120#define PSM_LEVEL_MAX PSM_LEVEL_NATIVE 121 122/* Logitech PS2++ protocol */ 123#define MOUSE_PS2PLUS_CHECKBITS(b) \ 124 ((((b[2] & 0x03) << 2) | 0x02) == (b[1] & 0x0f)) 125#define MOUSE_PS2PLUS_PACKET_TYPE(b) \ 126 (((b[0] & 0x30) >> 2) | ((b[1] & 0x30) >> 4)) 127 128/* some macros */ 129#define PSM_UNIT(dev) (minor(dev) >> 1) 130#define PSM_NBLOCKIO(dev) (minor(dev) & 1) 131#define PSM_MKMINOR(unit,block) (((unit) << 1) | ((block) ? 0:1)) 132 133/* ring buffer */ 134typedef struct ringbuf { 135 int count; /* # of valid elements in the buffer */ 136 int head; /* head pointer */ 137 int tail; /* tail poiner */ 138 unsigned char buf[PSM_BUFSIZE]; 139} ringbuf_t; 140 141/* data buffer */ 142typedef struct packetbuf { 143 unsigned char ipacket[16]; /* interim input buffer */ 144 int inputbytes; /* # of bytes in the input buffer */ 145} packetbuf_t; 146 147#ifndef PSM_PACKETQUEUE 148#define PSM_PACKETQUEUE 128 149#endif 150 151/* driver control block */ 152struct psm_softc { /* Driver status information */ 153 int unit; 154 struct selinfo rsel; /* Process selecting for Input */ 155 unsigned char state; /* Mouse driver state */ 156 int config; /* driver configuration flags */ 157 int flags; /* other flags */ 158 KBDC kbdc; /* handle to access the keyboard controller */ 159 struct resource *intr; /* IRQ resource */ 160 void *ih; /* interrupt handle */ 161 mousehw_t hw; /* hardware information */ 162 mousemode_t mode; /* operation mode */ 163 mousemode_t dflt_mode; /* default operation mode */ 164 mousestatus_t status; /* accumulated mouse movement */ 165 ringbuf_t queue; /* mouse status queue */ 166 packetbuf_t pqueue[PSM_PACKETQUEUE]; /* mouse data queue */ 167 int pqueue_start; /* start of data in queue */ 168 int pqueue_end; /* end of data in queue */ 169 int button; /* the latest button state */ 170 int xold; /* previous absolute X position */ 171 int yold; /* previous absolute Y position */ 172 int syncerrors; /* XXX: KILL ME!
