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@etherboot.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 <stdint.h> +#include <stdlib.h> +#include <stdio.h> +#include <string.h> +#include <gpxe/io.h> +#include <errno.h> +#include <unistd.h> +#include <byteswap.h> +#include <gpxe/pci.h> +#include <gpxe/if_ether.h> +#include <gpxe/ethernet.h> +#include <gpxe/iobuf.h> +#include <gpxe/netdevice.h> +#include <gpxe/spi_bit.h> +#include <gpxe/threewire.h> +#include <gpxe/nvo.h> + +#define TX_RING_SIZE 4 + +struct rtl8139_tx { + unsigned int next;
