/* * Lance ethernet driver for the MIPS processor based * DECstation family * * * adopted from sunlance.c by Richard van den Berg * * Copyright (C) 2002, 2003, 2005, 2006 Maciej W. Rozycki * * additional sources: * - PMAD-AA TURBOchannel Ethernet Module Functional Specification, * Revision 1.2 * * History: * * v0.001: The kernel accepts the code and it shows the hardware address. * * v0.002: Removed most sparc stuff, left only some module and dma stuff. * * v0.003: Enhanced base address calculation from proposals by * Harald Koerfgen and Thomas Riemer. * * v0.004: lance-regs is pointing at the right addresses, added prom * check. First start of address mapping and DMA. * * v0.005: started to play around with LANCE-DMA. This driver will not * work for non IOASIC lances. HK * * v0.006: added pointer arrays to lance_private and setup routine for * them in dec_lance_init. HK * * v0.007: Big shit. The LANCE seems to use a different DMA mechanism to * access the init block. This looks like one (short) word at a * time, but the smallest amount the IOASIC can transfer is a * (long) word. So we have a 2-2 padding here. Changed * lance_init_block accordingly. The 16-16 padding for the buffers * seems to be correct. HK * * v0.008: mods to make PMAX_LANCE work. 01/09/1999 triemer * * v0.009: Module support fixes, multiple interfaces support, various * bits. macro * * v0.010: Fixes for the PMAD mapping of the LANCE buffer and for the * PMAX requirement to only use halfword accesses to the * buffer. macro * * v0.011: Converted the PMAD to the driver model. macro */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include static const char version[] = "declance.c: v0.011 by Linux MIPS DECstation task force\n"; MODULE_AUTHOR("Linux MIPS DECstation task force"); MODULE_DESCRIPTION("DEC LANCE (DECstation onboard, PMAD-xx) driver"); MODULE_LICENSE("GPL"); #define __unused __attribute__ ((unused)) /* * card types */ #define ASIC_LANCE 1 #define PMAD_LANCE 2 #define PMAX_LANCE 3 #define LE_CSR0 0 #define LE_CSR1 1 #define LE_CSR2 2 #define LE_CSR3 3 #define LE_MO_PROM 0x8000 /* Enable promiscuous mode */ #define LE_C0_ERR 0x8000 /* Error: set if BAB, SQE, MISS or ME is set */ #define LE_C0_BABL 0x4000 /* BAB: Babble: tx timeout. */ #define LE_C0_CERR 0x2000 /* SQE: Signal quality error */ #define LE_C0_MISS 0x1000 /* MISS: Missed a packet */ #define LE_C0_MERR 0x0800 /* ME: Memory error */ #define LE_C0_RINT 0x0400 /* Received interrupt */ #define LE_C0_TINT 0x0200 /* Transmitter Interrupt */ #define LE_C0_IDON 0x0100 /* IFIN: Init finished. */ #define LE_C0_INTR 0x0080 /* Interrupt or error */ #define LE_C0_INEA 0x0040 /* Interrupt enable */ #define LE_C0_RXON 0x0020 /* Receiver on */ #define LE_C0_TXON 0x0010 /* Transmitter on */ #define LE_C0_TDMD 0x0008 /* Transmitter demand */ #define LE_C0_STOP 0x0004 /* Stop the card */ #define LE_C0_STRT 0x0002 /* Start the card */ #define LE_C0_INIT 0x0001 /* Init the card */ #define LE_C3_BSWP 0x4 /* SWAP */ #define LE_C3_ACON 0x2 /* ALE Control */ #define LE_C3_BCON 0x1 /* Byte control */ /* Receive message descriptor 1 */ #define LE_R1_OWN 0x8000 /* Who owns the entry */ #define LE_R1_ERR 0x4000 /* Error: if FRA, OFL, CRC or BUF is set */ #define LE_R1_FRA 0x2000 /* FRA: Frame error */ #define LE_R1_OFL 0x1000 /* OFL: Frame overflow */ #define LE_R1_CRC 0x0800 /* CRC error */ #define LE_R1_BUF 0x0400 /* BUF: Buffer error */ #define LE_R1_SOP 0x0200 /* Start of packet */ #define LE_R1_EOP 0x0100 /* End of packet */ #define LE_R1_POK 0x0300 /* Packet is complete: SOP + EOP */ /* Transmit message descriptor 1 */ #define LE_T1_OWN 0x8000 /* Lance owns the packet */ #define LE_T1_ERR 0x4000 /* Error summary */ #define LE_T1_EMORE 0x1000 /* Error: more than one retry needed */ #define LE_T1_EONE 0x0800 /* Error: one retry needed */ #define LE_T1_EDEF 0x0400 /* Error: deferred */ #define LE_T1_SOP 0x0200 /* Start of packet */ #define LE_T1_EOP 0x0100 /* End of packet */ #define LE_T1_POK 0x0300 /* Packet is complete: SOP + EOP */ #define LE_T3_BUF 0x8000 /* Buffer error */ #define LE_T3_UFL 0x4000 /* Error underflow */ #define LE_T3_LCOL 0x1000 /* Error late collision */ #define LE_T3_CLOS 0x0800 /* Error carrier loss */ #define LE_T3_RTY 0x0400 /* Error retry */ #define LE_T3_TDR 0x03ff /* Time Domain Reflectometry counter */ /* Define: 2^4 Tx buffers and 2^4 Rx buffers */ #ifndef LANCE_LOG_TX_BUFFERS #define LANCE_LOG_TX_BUFFERS 4 #define LANCE_LOG_RX_BUFFERS 4 #endif #define TX_RING_SIZE (1 << (LANCE_LOG_TX_BUFFERS)) #define TX_RING_MOD_MASK (TX_RING_SIZE - 1) #define RX_RING_SIZE (1 << (LANCE_LOG_RX_BUFFERS)) #define RX_RING_MOD_MASK (RX_RING_SIZE - 1) #define PKT_BUF_SZ 1536 #define RX_BUFF_SIZE PKT_BUF_SZ #define
