Low values - increase the system load (beware!) - - When loaded, a net device with the name 'bio0' becomes available, - which can be controlled with the usual 'ifconfig' command. - - It is possible to compile this driver into the kernel like other - (net) drivers. For this purpose, some source files (e.g. config-files - makefiles, Space.c) must be changed accordingly. (You may refer to - other drivers how to do it.) In this case, the device will be detected - at boot time and (probably) appear as 'eth0'. - - This code is based on several sources: - - The driver code for a parallel port ethernet adapter by - Donald Becker (see file 'atp.c' from the PC linux distribution) - - The ACSI code by Roman Hodek for the ATARI-ACSI harddisk support - and DMA handling. - - Very limited information about moving packets in and out of the - BIONET-adapter from the TCP package for TOS by BioData GmbH. - - Theory of Operation - ------------------- - Because the ATARI DMA port is usually shared between several - devices (eg. harddisk, floppy) we cannot block the ACSI bus - while waiting for interrupts. Therefore we use a polling mechanism - to fetch packets from the adapter. For the same reason, we send - packets without checking that the previous packet has been sent to - the LAN. We rely on the higher levels of the networking code to detect - missing packets and resend them. - - Before we access the ATARI DMA controller, we check if another - process is using the DMA. If not, we lock the DMA, perform one or - more packet transfers and unlock the DMA before returning. - We do not use 'stdma_lock' unconditionally because it is unclear - if the networking code can be set to sleep, which will happen if - another (possibly slow) device is using the DMA controller. - - The polling is done via timer interrupts which periodically - 'simulate' an interrupt from the Ethernet adapter. The time (in jiffies) - between polls varies depending on an estimate of the net activity. - The allowed range is given by the variable 'bionet_min_poll_time' - for the lower (fastest) limit and the constant 'MAX_POLL_TIME' - for the higher (slowest) limit. - - Whenever a packet arrives, we switch to fastest response by setting - the polling time to its lowest limit. If the following poll fails, - because no packets have arrived, we increase the time for the next - poll. When the net activity is low, the polling time effectively - stays at its maximum value, resulting in the lowest load for the - machine. - */ - -#define MAX_POLL_TIME 10 - -static char version[] = - "bionet.c:v1.0 06-feb-96 (c) Hartmut Laue.\n"; - -#include <linux/module.h> - -#include <linux/errno.h> -#include <linux/kernel.h> -#include <linux/jiffies.h> -#include <linux/types.h> -#include <linux/fcntl.h> -#include <linux/interrupt.h> -#include <linux/ioport.h> -#include <linux/in.h> -#include <linux/slab.h> -#include <linux/string.h> -#include <linux/delay.h> -#include <linux/timer.h> -#include <linux/init.h> -#include <linux/bitops.h> - -#include <linux/netdevice.h> -#include <linux/etherdevice.h> -#include <linux/skbuff.h> - -#include <asm/setup.h> -#include <asm/pgtable.h> -#include <asm/system.h> -#include <asm/io.h> -#include <asm/dma.h> -#include <asm/atarihw.h> -#include <asm/atariints.h> -#include <asm/atari_acsi.h> -#include <asm/atari_stdma.h> - - -/* use 0 for production, 1 for verification, >2 for debug - */ -#ifndef NET_DEBUG -#define NET_DEBUG 0 -#endif -/* - * Global variable 'bionet_debug'.

Low values - increase the system load (beware!) - - When loaded, a net device with the name 'eth?' becomes available, - which can be controlled with the usual 'ifconfig' command. - - It is possible to compile this driver into the kernel like other - (net) drivers. For this purpose, some source files (e.g. config-files - makefiles, Space.c) must be changed accordingly. (You may refer to - other drivers how to do it.) In this case, the device will be detected - at boot time and (probably) appear as 'eth0'. - - Theory of Operation - ------------------- - Because the ATARI DMA port is usually shared between several - devices (eg. harddisk, floppy) we cannot block the ACSI bus - while waiting for interrupts. Therefore we use a polling mechanism - to fetch packets from the adapter. For the same reason, we send - packets without checking that the previous packet has been sent to - the LAN. We rely on the higher levels of the networking code to detect - missing packets and resend them. - - Before we access the ATARI DMA controller, we check if another - process is using the DMA. If not, we lock the DMA, perform one or - more packet transfers and unlock the DMA before returning. - We do not use 'stdma_lock' unconditionally because it is unclear - if the networking code can be set to sleep, which will happen if - another (possibly slow) device is using the DMA controller. - - The polling is done via timer interrupts which periodically - 'simulate' an interrupt from the Ethernet adapter. The time (in jiffies) - between polls varies depending on an estimate of the net activity. - The allowed range is given by the variable 'bionet_min_poll_time' - for the lower (fastest) limit and the constant 'MAX_POLL_TIME' - for the higher (slowest) limit. - - Whenever a packet arrives, we switch to fastest response by setting - the polling time to its lowest limit. If the following poll fails, - because no packets have arrived, we increase the time for the next - poll. When the net activity is low, the polling time effectively - stays at its maximum value, resulting in the lowest load for the - machine. - */ - -#define MAX_POLL_TIME 10 - -static char *version = - "pamsnet.c:v0.2beta 30-mar-96 (c) Torsten Lang.\n"; - -#include <linux/module.h> - -#include <linux/kernel.h> -#include <linux/jiffies.h> -#include <linux/types.h> -#include <linux/fcntl.h> -#include <linux/interrupt.h> -#include <linux/ioport.h> -#include <linux/in.h> -#include <linux/slab.h> -#include <linux/string.h> -#include <linux/bitops.h> -#include <asm/system.h> -#include <asm/pgtable.h> -#include <asm/io.h> -#include <asm/dma.h> -#include <linux/errno.h> -#include <asm/atarihw.h> -#include <asm/atariints.h> -#include <asm/atari_stdma.h> -#include <asm/atari_acsi.h> - -#include <linux/delay.h> -#include <linux/timer.h> -#include <linux/init.h> - -#include <linux/netdevice.h> -#include <linux/etherdevice.h> -#include <linux/skbuff.h> - -#undef READ -#undef WRITE - -/* use 0 for production, 1 for verification, >2 for debug - */ -#ifndef NET_DEBUG -#define NET_DEBUG 0 -#endif -/* - * Global variable 'pamsnet_debug'.
