The Ratoc CFU2 uses a different chip. 18 * 19 * This chip puts the serial in USB. It implements USB by means of an eight 20 * bit I/O interface. It can be used for ISA, PCMCIA/CF, parallel port, 21 * serial port, or any eight bit interface. It has 256 bytes of memory, the 22 * first 16 of which are used for register access. There are two sets of 23 * registers for sending individual bus transactions. Because USB is polled, 24 * this organization means that some amount of card access must often be made 25 * when devices are attached, even if when they are not directly being used. 26 * A per-ms frame interrupt is necessary and many devices will poll with a 27 * per-frame bulk transfer. 28 * 29 * It is possible to write a little over two bytes to the chip (auto 30 * incremented) per full speed byte time on the USB. Unfortunately, 31 * auto-increment does not work reliably so write and bus speed is 32 * approximately the same for full speed devices. 33 * 34 * In addition to the 240 byte packet size limit for isochronous transfers, 35 * this chip has no means of determining the current frame number other than 36 * getting all 1ms SOF interrupts, which is not always possible even on a fast 37 * system. Isochronous transfers guarantee that transfers will never be 38 * retried in a later frame, so this can cause problems with devices beyond 39 * the difficulty in actually performing the transfer most frames. I tried 40 * implementing isoc transfers and was able to play CD-derrived audio via an 41 * iMic on a 2GHz PC, however it would still be interrupted at times and 42 * once interrupted, would stay out of sync. All isoc support has been 43 * removed. 44 * 45 * BUGS: all chip revisions have problems with low speed devices through hubs. 46 * The chip stops generating SOF with hubs that send SE0 during SOF. See 47 * comment in dointr(). All performance enhancing features of this chip seem 48 * not to work properly, most confirmed buggy in errata doc. 49 * 50 */ 51 52 /* 53 * The hard interrupt is the main entry point. Start, callbacks, and repeat 54 * are the only others called frequently. 55 * 56 * Since this driver attaches to pcmcia, card removal at any point should be 57 * expected and not cause panics or infinite loops. 58 */ 59 60 /* 61 * XXX TODO: 62 * copy next output packet while transfering 63 * usb suspend 64 * could keep track of known values of all buffer space? 65 * combined print/log function for errors 66 * 67 * ub_usepolling support is untested and may not work 68 */ 69 70 #include <sys/cdefs.h> 71 __KERNEL_RCSID(0, "$NetBSD: sl811hs.c,v 1.104 2020/09/30 05:04:54 simonb Exp $"); 72 73 #ifdef _KERNEL_OPT 74 #include "opt_slhci.h" 75 #include "opt_usb.h" 76 #endif 77 78 #include <sys/param.h> 79 80 #include <sys/bus.h> 81 #include <sys/cpu.h> 82 #include <sys/device.h> 83 #include <sys/gcq.h> 84 #include <sys/intr.h> 85 #include <sys/kernel.h> 86 #include <sys/kmem.h> 87 #include <sys/proc.h> 88 #include <sys/queue.h> 89 #include <sys/sysctl.h> 90 #include <sys/systm.h> 91 92 #include <dev/usb/usb.h> 93 #include <dev/usb/usbdi.h> 94 #include <dev/usb/usbdivar.h> 95 #include <dev/usb/usbhist.h> 96 #include <dev/usb/usb_mem.h> 97 #include <dev/usb/usbdevs.h> 98 #include <dev/usb/usbroothub.h> 99 100 #include <dev/ic/sl811hsreg.h> 101 #include <dev/ic/sl811hsvar.h> 102 103 #define Q_CB 0 /* Control/Bulk */ 104 #define Q_NEXT_CB 1 105 #define Q_MAX_XFER Q_CB 106 #define Q_CALLBACKS 2 107 #define Q_MAX Q_CALLBACKS 108 109 #define F_AREADY (0x00000001) 110 #define F_BREADY (0x00000002) 111 #define F_AINPROG (0x00000004) 112 #define F_BINPROG (0x00000008) 113 #define F_LOWSPEED (0x00000010) 114 #define F_UDISABLED (0x00000020) /* Consider disabled for USB */ 115 #define F_NODEV (0x00000040) 116 #define F_ROOTINTR (0x00000080) 117 #define F_REALPOWER (0x00000100) /* Actual power state */ 118 #define F_POWER (0x00000200) /* USB reported power state */ 119 #define F_ACTIVE (0x00000400) 120 #define F_CALLBACK (0x00000800) /* Callback scheduled */ 121 #define F_SOFCHECK1 (0x00001000) 122 #define F_SOFCHECK2 (0x00002000) 123 #define F_CRESET (0x00004000) /* Reset done not reported */ 124 #define F_CCONNECT (0x00008000) /* Connect change not reported */ 125 #define F_RESET (0x00010000) 126 #define F_ISOC_WARNED (0x00020000) 127 #define F_LSVH_WARNED (0x00040000) 128 129 #define F_DISABLED (F_NODEV|F_UDISABLED) 130 #define F_CHANGE (F_CRESET|F_CCONNECT) 131 132 #ifdef SLHCI_TRY_LSVH 133 unsigned int slhci_try_lsvh = 1; 134 #else 135 unsigned int slhci_try_lsvh = 0; 136 #endif 137 138 #define ADR 0 139 #define LEN 1 140 #define PID 2 141 #define DEV 3 142 #define STAT 2 143 #define CONT 3 144 145 #define A 0 146 #define B 1 147 148 static const uint8_t slhci_tregs[2][4] = 149 {{SL11_E0ADDR, SL11_E0LEN, SL11_E0PID, SL11_E0DEV }, 150 {SL11_E1ADDR, SL11_E1LEN, SL11_E1PID, SL11_E1DEV }}; 151 152 #define PT_ROOT_CTRL 0 153 #define PT_ROOT_INTR 1 154 #define PT_CTRL_SETUP 2 155 #define PT_CTRL_DATA 3 156 #define PT_CTRL_STATUS 4 157 #define PT_INTR 5 158 #define PT_BULK 6 159 #define PT_MAX 6 160 161 #ifdef SLHCI_DEBUG 162 #define SLHCI_MEM_ACCOUNTING 163 #endif 164 165 /* 166 * Maximum allowable reserved bus time.
