It 47 * would also make the code more readable and easier to follow. 48 * - (Related to above) Use the header part of adbCommand to 49 * reduce the number of copies we have to do of the data. 50 * - (Related to above) Actually implement the adbOutbound queue. 51 * This is fairly easy once you switch all the intr routines 52 * over to using adbCommand structs directly. 53 * - There is a bug in the state machine of adb_intr_cuda 54 * code that causes hangs, especially on 030 machines, probably 55 * because of some timing issues. Because I have been unable to 56 * determine the exact cause of this bug, I used the timeout function 57 * to check for and recover from this condition. If anyone finds 58 * the actual cause of this bug, the calls to timeout and the 59 * adb_cuda_tickle routine can be removed. 60 */ 61 62 #include <sys/param.h> 63 #include <sys/cdefs.h> 64 #include <sys/systm.h> 65 #include <sys/callout.h> 66 #include <sys/device.h> 67 68 #include <machine/param.h> 69 #include <machine/cpu.h> 70 #include <machine/adbsys.h> 71 72 #include <macppc/dev/viareg.h> 73 #include <macppc/dev/adbvar.h> 74 75 #define printf_intr printf 76 77 #ifdef DEBUG 78 #ifndef ADB_DEBUG 79 #define ADB_DEBUG 80 #endif 81 #endif 82 83 /* some misc. leftovers */ 84 #define vPB 0x0000 85 #define vPB3 0x08 86 #define vPB4 0x10 87 #define vPB5 0x20 88 #define vSR_INT 0x04 89 #define vSR_OUT 0x10 90 91 /* the type of ADB action that we are currently preforming */ 92 #define ADB_ACTION_NOTREADY 0x1 /* has not been initialized yet */ 93 #define ADB_ACTION_IDLE 0x2 /* the bus is currently idle */ 94 #define ADB_ACTION_OUT 0x3 /* sending out a command */ 95 #define ADB_ACTION_IN 0x4 /* receiving data */ 96 #define ADB_ACTION_POLLING 0x5 /* polling - II only */ 97 98 /* 99 * These describe the state of the ADB bus itself, although they 100 * don't necessarily correspond directly to ADB states. 101 * Note: these are not really used in the IIsi code. 102 */ 103 #define ADB_BUS_UNKNOWN 0x1 /* we don't know yet - all models */ 104 #define ADB_BUS_IDLE 0x2 /* bus is idle - all models */ 105 #define ADB_BUS_CMD 0x3 /* starting a command - II models */ 106 #define ADB_BUS_ODD 0x4 /* the "odd" state - II models */ 107 #define ADB_BUS_EVEN 0x5 /* the "even" state - II models */ 108 #define ADB_BUS_ACTIVE 0x6 /* active state - IIsi models */ 109 #define ADB_BUS_ACK 0x7 /* currently ACKing - IIsi models */ 110 111 /* 112 * Shortcuts for setting or testing the VIA bit states. 113 * Not all shortcuts are used for every type of ADB hardware. 114 */ 115 #define ADB_SET_STATE_IDLE_II() via_reg_or(VIA1, vBufB, (vPB4 | vPB5)) 116 #define ADB_SET_STATE_IDLE_IISI() via_reg_and(VIA1, vBufB, ~(vPB4 | vPB5)) 117 #define ADB_SET_STATE_IDLE_CUDA() via_reg_or(VIA1, vBufB, (vPB4 | vPB5)) 118 #define ADB_SET_STATE_CMD() via_reg_and(VIA1, vBufB, ~(vPB4 | vPB5)) 119 #define ADB_SET_STATE_EVEN() write_via_reg(VIA1, vBufB, \ 120 (read_via_reg(VIA1, vBufB) | vPB4) & ~vPB5) 121 #define ADB_SET_STATE_ODD() write_via_reg(VIA1, vBufB, \ 122 (read_via_reg(VIA1, vBufB) | vPB5) & ~vPB4 ) 123 #define ADB_SET_STATE_ACTIVE() via_reg_or(VIA1, vBufB, vPB5) 124 #define ADB_SET_STATE_INACTIVE() via_reg_and(VIA1, vBufB, ~vPB5) 125 #define ADB_SET_STATE_TIP() via_reg_and(VIA1, vBufB, ~vPB5) 126 #define ADB_CLR_STATE_TIP() via_reg_or(VIA1, vBufB, vPB5) 127 #define ADB_SET_STATE_ACKON() via_reg_or(VIA1, vBufB, vPB4) 128 #define ADB_SET_STATE_ACKOFF() via_reg_and(VIA1, vBufB, ~vPB4) 129 #define ADB_TOGGLE_STATE_ACK_CUDA() via_reg_xor(VIA1, vBufB, vPB4) 130 #define ADB_SET_STATE_ACKON_CUDA() via_reg_and(VIA1, vBufB, ~vPB4) 131 #define ADB_SET_STATE_ACKOFF_CUDA() via_reg_or(VIA1, vBufB, vPB4) 132 #define ADB_SET_SR_INPUT() via_reg_and(VIA1, vACR, ~vSR_OUT) 133 #define ADB_SET_SR_OUTPUT() via_reg_or(VIA1, vACR, vSR_OUT) 134 #define ADB_SR() read_via_reg(VIA1, vSR) 135 #define ADB_VIA_INTR_ENABLE() write_via_reg(VIA1, vIER, 0x84) 136 #define ADB_VIA_INTR_DISABLE() write_via_reg(VIA1, vIER, 0x04) 137 #define ADB_VIA_CLR_INTR() write_via_reg(VIA1, vIFR, 0x04) 138 #define ADB_INTR_IS_OFF (vPB3 == (read_via_reg(VIA1, vBufB) & vPB3)) 139 #define ADB_INTR_IS_ON (0 == (read_via_reg(VIA1, vBufB) & vPB3)) 140 #define ADB_SR_INTR_IS_OFF (0 == (read_via_reg(VIA1, vIFR) & vSR_INT)) 141 #define ADB_SR_INTR_IS_ON (vSR_INT == (read_via_reg(VIA1, \ 142 vIFR) & vSR_INT)) 143 144 /* 145 * This is the delay that is required (in uS) between certain 146 * ADB transactions.
