This confused the RTL8139 thoroughly. It destroyed the + Rx ring contents by dumping the 2K FIFO contents right where we wanted to + get the next packet. Oh well, what fun. + + 18 Jan 2000 mdc@thinguin.org (Marty Connor) + Drastically simplified error handling. Basically, if any error + in transmission or reception occurs, the card is reset. + Also, pointed all transmit descriptors to the same buffer to + save buffer space. This should decrease driver size and avoid + corruption because of exceeding 32K during runtime. + + 28 Jul 1999 (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de) + rtl_poll was quite broken: it used the RxOK interrupt flag instead + of the RxBufferEmpty flag which often resulted in very bad + transmission performace - below 1kBytes/s. + +*/ + +#include +#include +#include +#include +#include + +#if defined(CONFIG_CMD_NET) && defined(CONFIG_NET_MULTI) && \ + defined(CONFIG_RTL8139) + +#define TICKS_PER_SEC CFG_HZ +#define TICKS_PER_MS (TICKS_PER_SEC/1000) + +#define RTL_TIMEOUT (1*TICKS_PER_SEC) + +#define ETH_FRAME_LEN 1514 +#define ETH_ALEN 6 +#define ETH_ZLEN 60 + +/* PCI Tuning Parameters + Threshold is bytes transferred to chip before transmission starts. */ +#define TX_FIFO_THRESH 256 /* In bytes, rounded down to 32 byte units. */ +#define RX_FIFO_THRESH 4 /* Rx buffer level before first PCI xfer. */ +#define RX_DMA_BURST 4 /* Maximum PCI burst, '4' is 256 bytes */ +#define TX_DMA_BURST 4 /* Calculate as 16<priv, a) +#define phys_to_bus(a) pci_phys_to_mem((pci_dev_t)dev->priv, a) + +/* Symbolic offsets to registers. */ +enum RTL8139_registers { + MAC0=0, /* Ethernet hardware address. */ + MAR0=8, /* Multicast filter. */ + TxStatus0=0x10, /* Transmit status (four 32bit registers). */ + TxAddr0=0x20, /* Tx descriptors (also four 32bit). */ + RxBuf=0x30, RxEarlyCnt=0x34, RxEarlyStatus=0x36, + ChipCmd=0x37, RxBufPtr=0x38, RxBufAddr=0x3A, + IntrMask=0x3C, IntrStatus=0x3E, + TxConfig=0x40, RxConfig=0x44, + Timer=0x48, /* general-purpose counter. */ + RxMissed=0x4C, /* 24 bits valid, write clears. */ + Cfg9346=0x50, Config0=0x51, Config1=0x52, + TimerIntrReg=0x54, /* intr if gp counter reaches this value */ + MediaStatus=0x58, + Config3=0x59, + MultiIntr=0x5C, + RevisionID=0x5E, /* revision of the RTL8139 chip */ + TxSummary=0x60, + MII_BMCR=0x62, MII_BMSR=0x64, NWayAdvert=0x66, NWayLPAR=0x68, + NWayExpansion=0x6A, + DisconnectCnt=0x6C, FalseCarrierCnt=0x6E, + NWayTestReg=0x70, + RxCnt=0x72, /* packet received counter */ + CSCR=0x74, /* chip status and configuration register */ + PhyParm1=0x78,TwisterParm=0x7c,PhyParm2=0x80, /* undocumented */ + /* from 0x84 onwards are a number of power management/wakeup frame + * definitions we will probably never need to know about. */ +};

This is a bit of a hack, but currently the only - way to make room for the Etherboot features that need substantial amounts - of code like the ANSI console support. Currently the buffer is just below - 0x10000, so this even conforms to the tagged boot image specification, - which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000. My - interpretation of this "reserved" is that Etherboot may do whatever it - likes, as long as its environment is kept intact (like the BIOS - variables). Hopefully fixed rtl_poll() once and for all. The symptoms - were that if Etherboot was left at the boot menu for several minutes, the - first eth_poll failed. Seems like I am the only person who does this. - First of all I fixed the debugging code and then set out for a long bug - hunting session. It took me about a week full time work - poking around - various places in the driver, reading Don Becker's and Jeff Garzik's Linux - driver and even the FreeBSD driver (what a piece of crap!) - and - eventually spotted the nasty thing: the transmit routine was acknowledging - each and every interrupt pending, including the RxOverrun and RxFIFIOver - interrupts. This confused the RTL8139 thoroughly. It destroyed the - Rx ring contents by dumping the 2K FIFO contents right where we wanted to - get the next packet. Oh well, what fun. - - 18 Jan 2000 mdc@thinguin.org (Marty Connor) - Drastically simplified error handling. Basically, if any error - in transmission or reception occurs, the card is reset. - Also, pointed all transmit descriptors to the same buffer to - save buffer space. This should decrease driver size and avoid - corruption because of exceeding 32K during runtime. - - 28 Jul 1999 (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de) - rtl_poll was quite broken: it used the RxOK interrupt flag instead - of the RxBufferEmpty flag which often resulted in very bad - transmission performace - below 1kBytes/s. - -*/ - -#include -#include -#include -#include -#include - -#if defined(CONFIG_CMD_NET) && defined(CONFIG_NET_MULTI) && \ - defined(CONFIG_RTL8139) - -#define TICKS_PER_SEC CFG_HZ -#define TICKS_PER_MS (TICKS_PER_SEC/1000) - -#define RTL_TIMEOUT (1*TICKS_PER_SEC) - -#define ETH_FRAME_LEN 1514 -#define ETH_ALEN 6 -#define ETH_ZLEN 60 - -/* PCI Tuning Parameters - Threshold is bytes transferred to chip before transmission starts. */ -#define TX_FIFO_THRESH 256 /* In bytes, rounded down to 32 byte units. */ -#define RX_FIFO_THRESH 4 /* Rx buffer level before first PCI xfer. */ -#define RX_DMA_BURST 4 /* Maximum PCI burst, '4' is 256 bytes */ -#define TX_DMA_BURST 4 /* Calculate as 16<priv, a) -#define phys_to_bus(a) pci_phys_to_mem((pci_dev_t)dev->priv, a) - -/* Symbolic offsets to registers. */ -enum RTL8139_registers { - MAC0=0, /* Ethernet hardware address. */ - MAR0=8, /* Multicast filter. */ - TxStatus0=0x10, /* Transmit status (four 32bit registers). */ - TxAddr0=0x20, /* Tx descriptors (also four 32bit). */ - RxBuf=0x30, RxEarlyCnt=0x34, RxEarlyStatus=0x36, - ChipCmd=0x37, RxBufPtr=0x38, RxBufAddr=0x3A, - IntrMask=0x3C, IntrStatus=0x3E, - TxConfig=0x40, RxConfig=0x44, - Timer=0x48, /* general-purpose counter. */ - RxMissed=0x4C, /* 24 bits valid, write clears. */ - Cfg9346=0x50, Config0=0x51, Config1=0x52, - TimerIntrReg=0x54, /* intr if gp counter reaches this value */ - MediaStatus=0x58, - Config3=0x59, - MultiIntr=0x5C, - RevisionID=0x5E, /* revision of the RTL8139 chip */ - TxSummary=0x60, - MII_BMCR=0x62, MII_BMSR=0x64, NWayAdvert=0x66, NWayLPAR=0x68, - NWayExpansion=0x6A, - DisconnectCnt=0x6C, FalseCarrierCnt=0x6E, - NWayTestReg=0x70, - RxCnt=0x72, /* packet received counter */ - CSCR=0x74, /* chip status and configuration register */ - PhyParm1=0x78,TwisterParm=0x7c,PhyParm2=0x80, /* undocumented */ - /* from 0x84 onwards are a number of power management/wakeup frame - * definitions we will probably never need to know about. */ -};
