-Notes:
-
-The major number for SLM printers is 28 (like ACSI), but as a character
-device, not block device. The minor number is the number of the printer (if
-you have more than one SLM; currently max. 2 (#define-constant) SLMs are
-supported). The device can be opened for reading and writing. If reading it,
-you get some status infos (MODE SENSE data). Writing mode is used for the data
-to be printed. Some ioctls allow to get the printer status and to tune printer
-modes and some internal variables.
-
-A special problem of the SLM driver is the timing and thus the buffering of
-the print data. The problem is that all the data for one page must be present
-in memory when printing starts, else --when swapping occurs-- the timing could
-not be guaranteed. There are several ways to assure this:
-
- 1) Reserve a buffer of 1196k (maximum page size) statically by
- atari_stram_alloc(). The data are collected there until they're complete,
- and then printing starts. Since the buffer is reserved, no further
- considerations about memory and swapping are needed. So this is the
- simplest method, but it needs a lot of memory for just the SLM.
-
- An striking advantage of this method is (supposed the SLM_CONT_CNT_REPROG
- method works, see there), that there are no timing problems with the DMA
- anymore.
-
- 2) The other method would be to reserve the buffer dynamically each time
- printing is required. I could think of looking at mem_map where the
- largest unallocted ST-RAM area is, taking the area, and then extending it
- by swapping out the neighbored pages, until the needed size is reached.
- This requires some mm hacking, but seems possible. The only obstacle could
- be pages that cannot be swapped out (reserved pages)...
-
- 3) Another possibility would be to leave the real data in user space and to
- work with two dribble buffers of about 32k in the driver: While the one
- buffer is DMAed to the SLM, the other can be filled with new data. But
- to keep the timing, that requires that the user data remain in memory and
- are not swapped out. Requires mm hacking, too, but maybe not so bad as
- method 2).

-/* bionet.c BioNet-100 device driver for linux68k.
- *
- * Version: @(#)bionet.c 1.0 02/06/96
- *
- * Author: Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- * Some changes in bionet_poll_rx by Karl-Heinz Lohner
- *
- What is it ?
- ------------
- This driver controls the BIONET-100 LAN-Adapter which connects
- an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
- This version can be compiled as a loadable module (See the
- compile command at the bottom of this file).
- At load time, you can optionally set the debugging level and the
- fastest response time on the command line of 'insmod'.
-
- 'bionet_debug'
- controls the amount of diagnostic messages:
- 0 : no messages
- >0 : see code for meaning of printed messages
-
- 'bionet_min_poll_time' (always >=1)
- gives the time (in jiffies) between polls. 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.

- *
- * Version: @(#)PAMsNet.c 0.2ß 03/31/96
- *
- * Author: Torsten Lang <Torsten.Lang@ap.physik.uni-giessen.de>
- * <Torsten.Lang@jung.de>
- *
- * This driver is based on my driver PAMSDMA.c for MiNT-Net and
- * on the driver bionet.c written by
- * Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- What is it ?
- ------------
- This driver controls the PAMsNet LAN-Adapter which connects
- an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
- This version can be compiled as a loadable module (See the
- compile command at the bottom of this file).
- At load time, you can optionally set the debugging level and the
- fastest response time on the command line of 'insmod'.
-
- 'pamsnet_debug'
- controls the amount of diagnostic messages:
- 0 : no messages
- >0 : see code for meaning of printed messages
-
- 'pamsnet_min_poll_time' (always >=1)
- gives the time (in jiffies) between polls. 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.

- * Definitions of commands understood by the PAMs DMA adaptor.
- *
- * In general the DMA adaptor uses LUN 0, 5, 6 and 7 on one ID changeable
- * by the PAM's Net software.
- *
- * LUN 0 works as a harddisk. You can boot the PAM's Net driver there.
- * LUN 5 works as a harddisk and lets you access the RAM and some I/O HW
- * area. In sector 0, bytes 0x38-0x3d you find the ethernet HW address
- * of the adaptor.
- * LUN 6 works as a harddisk and lets you access the firmware ROM.
- * LUN 7 lets you send and receive packets.
- *
- * Some commands like the INQUIRY command work identical on all used LUNs.
- *
- * UNKNOWN1 seems to read some data.
- * Command length is 6 bytes.
- * UNKNOWN2 seems to read some data (command byte 1 must be !=0). The
- * following bytes seem to be something like an allocation length.
- * Command length is 6 bytes.
- * READPKT reads a packet received by the DMA adaptor.
- * Command length is 6 bytes.
- * WRITEPKT sends a packet transferred by the following DMA phase. The length
- * of the packet is transferred in command bytes 3 and 4.
- * The adaptor automatically replaces the src hw address in an ethernet
- * packet by its own hw address.
- * Command length is 6 bytes.
- * INQUIRY has the same function as the INQUIRY command supported by harddisks
- * and other SCSI devices. It lets you detect which device you found
- * at a given address.
- * Command length is 6 bytes.
- * START initializes the DMA adaptor. After this command it is able to send
- * and receive packets. There is no status byte returned!
- * Command length is 1 byte.
- * NUMPKTS gives back the number of received packets waiting in the queue in
- * the status byte.
- * Command length is 1 byte.
- * UNKNOWN3
- * UNKNOWN4 Function of these three commands is unknown.
- * UNKNOWN5 The command length of these three commands is 1 byte.
- * DESELECT immediately deselects the DMA adaptor. May important with interrupt
- * driven operation.
- * Command length is 1 byte.
- * STOP resets the DMA adaptor. After this command packets can no longer
- * be received or transferred.
- * Command length is 6 byte.
