I -haven't the foggiest why. My Specialix card is now at 0x180. My -other computer runs just fine with the Specialix card at 0x100.... -The card occupies 4 addresses, but actually only two are really used. - -The PCI version doesn't have any dip switches. The BIOS assigns -an IO address. - -The driver now still autoprobes at 0x100, 0x180, 0x250 and 0x260. If -that causes trouble for you, please report that. I'll remove -autoprobing then. - -The driver will tell the card what IRQ to use, so you don't have to -change any jumpers to change the IRQ. Just use a command line -argument (irq=xx) to the insmod program to set the interrupt. - -The BIOS assigns the IRQ on the PCI version. You have no say in what -IRQ to use in that case. - -If your specialix cards are not at the default locations, you can use -the kernel command line argument "specialix=io0,irq0,io1,irq1...". -Here "io0" is the io address for the first card, and "irq0" is the -irq line that the first card should use. And so on. - -Examples. - -You use the driver as a module and have three cards at 0x100, 0x250 -and 0x180. And some way or another you want them detected in that -order.

This would become - - append="specialix=0x100,9,0x250,11,0x180,15" - -in your /etc/lilo.conf file if you use lilo. - -The Specialix driver is slightly odd: It allows you to have the second -or third card detected without having a first card. This has -advantages and disadvantages. A slot that isn't filled by an ISA card, -might be filled if a PCI card is detected. Thus if you have an ISA -card at 0x250 and a PCI card, you would get: - -sx0: specialix IO8+ Board at 0x100 not found. -sx1: specialix IO8+ Board at 0x180 not found. -sx2: specialix IO8+ board detected at 0x250, IRQ 12, CD1865 Rev.

B. -sx1: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B. - -ISA probing is aborted after the IO address you gave is exhausted, and -the PCI card is now detected as the second card.

The rev 1.3 and newer boards use a CL-CD1865. These chips -are officially capable of 115k2. - -The Specialix card uses a 25MHz crystal (in times two mode, which in -fact is a divided by two mode). This is not enough to reach the rated -115k2 on all ports at the same time. With this clock rate you can only -do 37% of this rate. This means that at 115k2 on all ports you are -going to lose characters (The chip cannot handle that many incoming -bits at this clock rate.) (Yes, you read that correctly: there is a -limit to the number of -=bits=- per second that the chip can handle.) - -If you near the "limit" you will first start to see a graceful -degradation in that the chip cannot keep the transmitter busy at all -times. However with a central clock this slow, you can also get it to -miss incoming characters. The driver will print a warning message when -you are outside the official specs. The messages usually show up in -the file /var/log/messages . - -The specialix card cannot reliably do 115k2. If you use it, you have -to do "extensive testing" (*) to verify if it actually works. - -When "mgetty" communicates with my modem at 115k2 it reports: -got: +++[0d]ATQ0V1H0[0d][0d][8a]O[cb][0d][8a] - ^^^^ ^^^^ ^^^^ - -The three characters that have the "^^^" under them have suffered a -bit error in the highest bit. In conclusion: I've tested it, and found -that it simply DOESN'T work for me.

The default -behaviour is specialix.sx_rtscts = 0 where the pin behaves as DTR when -hardware handshaking is off. It behaves as the RTS hardware -handshaking signal when hardware handshaking is selected. - -When you use this, you have to use the appropriate cable. The -cable will either be compatible with hardware handshaking or with -software handshaking. So switching on the fly is not really an -option. - -I actually prefer to use the "specialix.sx_rtscts=1" option. -This makes the DTR/RTS pin always an RTS pin, and ioctls to -change DTR are always ignored. I have a cable that is configured -for this. - - -Ports and devices -================= - -Port 0 is the one furthest from the card-edge connector. - -Devices: - -You should make the devices as follows: - -bash -cd /dev -for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 \ - 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 -do - echo -n "$i " - mknod /dev/ttyW$i c 75 $i - mknod /dev/cuw$i c 76 $i -done -echo "" - -If your system doesn't come with these devices preinstalled, bug your -linux-vendor about this. They have had ample time to get this -implemented by now. - -You cannot have more than 4 boards in one computer. The card only -supports 4 different interrupts. If you really want this, contact me -about this and I'll give you a few tips (requires soldering iron).... - -If you have enough PCI slots, you can probably use more than 4 PCI -versions of the card though.... - -The PCI version of the card cannot adhere to the mechanical part of -the PCI spec because the 8 serial connectors are simply too large. If -it doesn't fit in your computer, bring back the card. - - ------------------------------------------------------------------------- - - - Fixed bugs and restrictions: - - During initialization, interrupts are blindly turned on. - Having a shadow variable would cause an extra memory - access on every IO instruction. - - The interrupt (on the card) should be disabled when we - don't allocate the Linux end of the interrupt. This allows - a different driver/card to use it while all ports are not in - use..... (a la standard serial port) - == An extra _off variant of the sx_in and sx_out macros are - now available. They don't set the interrupt enable bit. - These are used during initialization. Normal operation uses - the old variant which enables the interrupt line. - - RTS/DTR issue needs to be implemented according to - specialix' spec. - I kind of like the "determinism" of the current - implementation. Compile time flag? - == Ok. Compile time flag! Default is how Specialix likes it. - == Now a config time flag! Gets saved in your config file. Neat! - - Can you set the IO address from the lilo command line? - If you need this, bug me about it, I'll make it. - == Hah! No bugging needed. Fixed! :-) - - Cirrus logic hasn't gotten back to me yet why the CD1865 can - and the CD1864 can't do 115k2. I suspect that this is - because the CD1864 is not rated for 33MHz operation. - Therefore the CD1864 versions of the card can't do 115k2 on - all ports just like the CD1865 versions. The driver does - not block 115k2 on CD1864 cards. - == I called the Cirrus Logic representative here in Holland. - The CD1864 databook is identical to the CD1865 databook, - except for an extra warning at the end. Similar Bit errors - have been observed in testing at 115k2 on both an 1865 and - a 1864 chip. I see no reason why I would prohibit 115k2 on - 1864 chips and not do it on 1865 chips. Actually there is - reason to prohibit it on BOTH chips. I print a warning. - If you use 115k2, you're on your own. - - A spiky CD may send spurious HUPs. Also in CLOCAL??? - -- A fix for this turned out to be counter productive. - Different fix? Current behaviour is acceptable? - -- Maybe the current implementation is correct. If anybody - gets bitten by this, please report, and it will get fixed. - - -- Testing revealed that when in CLOCAL, the problem doesn't - occur. As warned for in the CD1865 manual, the chip may - send modem intr's on a spike. We could filter those out, - but that would be a cludge anyway (You'd still risk getting - a spurious HUP when two spikes occur.)..... - - - - Bugs & restrictions: - - This is a difficult card to autoprobe. - You have to WRITE to the address register to even - read-probe a CD186x register.

Ever misplace your Linux -kernel sources? And the manual of one of the boards in your computer? - - -Theory of operation -=================== - -An important thing to know is that the driver itself doesn't have the -firmware for the card. This means that you need the separate package -"sx_firmware". For now you can get the source at - - ftp://ftp.bitwizard.nl/specialix/sx_firmware_.tgz - -The firmware load needs a "misc" device, so you'll need to enable the -"Support for user misc device modules" in your kernel configuration. -The misc device needs to be called "/dev/specialix_sxctl". It needs -misc major 10, and minor number 167 (assigned by HPA). The section -on creating device files below also creates this device. - -After loading the sx.o module into your kernel, the driver will report -the number of cards detected, but because it doesn't have any -firmware, it will not be able to determine the number of ports. Only -when you then run "sx_firmware" will the firmware be downloaded and -the rest of the driver initialized. At that time the sx_firmware -program will report the number of ports installed. - -In contrast with many other multi port serial cards, some of the data -structures are only allocated when the card knows the number of ports -that are connected. This means we won't waste memory for 120 port -descriptor structures when you only have 8 ports. If you experience -problems due to this, please report them: I haven't seen any. - - -Interrupts -========== - -A multi port serial card, would generate a horrendous amount of -interrupts if it would interrupt the CPU for every received -character. Even more than 10 years ago, the trick not to use -interrupts but to poll the serial cards was invented. - -The SX card allow us to do this two ways. First the card limits its -own interrupt rate to a rate that won't overwhelm the CPU. Secondly, -we could forget about the cards interrupt completely and use the -internal timer for this purpose. - -Polling the card can take up to a few percent of your CPU. Using the -interrupts would be better if you have most of the ports idle. Using -timer-based polling is better if your card almost always has work to -do. You save the separate interrupt in that case. - -In any case, it doesn't really matter all that much. - -The most common problem with interrupts is that for ISA cards in a PCI -system the BIOS has to be told to configure that interrupt as "legacy -ISA". Otherwise the card can pull on the interrupt line all it wants -but the CPU won't see this. - -If you can't get the interrupt to work, remember that polling mode is -more efficient (provided you actually use the card intensively). - - -Allowed Configurations -====================== - -Some configurations are disallowed. Even though at a glance they might -seem to work, they are known to lockup the bus between the host card -and the device concentrators. You should respect the drivers decision -not to support certain configurations. It's there for a reason. - -Warning: Seriously technical stuff ahead. Executive summary: Don't use -SX cards except configured at a 64k boundary. Skip the next paragraph. - -The SX cards can theoretically be placed at a 32k boundary. So for -instance you can put an SX card at 0xc8000-0xd7fff. This is not a -"recommended configuration". ISA cards have to tell the bus controller -how they like their timing. Due to timing issues they have to do this -based on which 64k window the address falls into. This means that the -32k window below and above the SX card have to use exactly the same -timing as the SX card. That reportedly works for other SX cards. But -you're still left with two useless 32k windows that should not be used -by anybody else. - - -Configuring the driver -====================== - -PCI cards are always detected. The driver auto-probes for ISA cards at -some sensible addresses. Please report if the auto-probe causes trouble -in your system, or when a card isn't detected. - -I'm afraid I haven't implemented "kernel command line parameters" yet. -This means that if the default doesn't work for you, you shouldn't use -the compiled-into-the-kernel version of the driver. Use a module -instead. If you convince me that you need this, I'll make it for -you. Deal? - -I'm afraid that the module parameters are a bit clumsy. If you have a -better idea, please tell me. - -You can specify several parameters: - - sx_poll: number of jiffies between timer-based polls. - - Set this to "0" to disable timer based polls. - Initialization of cards without a working interrupt - will fail. - - Set this to "1" if you want a polling driver. - (on Intel: 100 polls per second). If you don't use - fast baud rates, you might consider a value like "5". - (If you don't know how to do the math, use 1). - - sx_slowpoll: Number of jiffies between timer-based polls. - Set this to "100" to poll once a second. - This should get the card out of a stall if the driver - ever misses an interrupt. I've never seen this happen, - and if it does, that's a bug. Tell me. - - sx_maxints: Number of interrupts to request from the card. - The card normally limits interrupts to about 100 per - second to offload the host CPU. You can increase this - number to reduce latency on the card a little. - Note that if you give a very high number you can overload - your CPU as well as the CPU on the host card. This setting - is inaccurate and not recommended for SI cards (But it - works). - - sx_irqmask: The mask of allowable IRQs to use. I suggest you set - this to 0 (disable IRQs all together) and use polling if - the assignment of IRQs becomes problematic. This is defined - as the sum of (1 << irq) 's that you want to allow. So - sx_irqmask of 8 (1 << 3) specifies that only irq 3 may - be used by the SX driver. If you want to specify to the - driver: "Either irq 11 or 12 is ok for you to use", then - specify (1 << 11) | (1 << 12) = 0x1800 . - - sx_debug: You can enable different sorts of debug traces with this. - At "-1" all debugging traces are active. You'll get several - times more debugging output than you'll get characters - transmitted. - - -Baud rates -========== - -Theoretically new SXDCs should be capable of more than 460k -baud. However the line drivers usually give up before that. Also the -CPU on the card may not be able to handle 8 channels going at full -blast at that speed. Moreover, the buffers are not large enough to -allow operation with 100 interrupts per second. You'll have to realize -that the card has a 256 byte buffer, so you'll have to increase the -number of interrupts per second if you have more than 256*100 bytes -per second to transmit. If you do any performance testing in this -area, I'd be glad to hear from you... - -(Psst Linux users..... I think the Linux driver is more efficient than -the driver for other OSes. If you can and want to benchmark them -against each other, be my guest, and report your findings...... :-) - - -Ports and devices -================= - -Port 0 is the top connector on the module closest to the host -card. Oh, the ports on the SXDCs and TAs are labelled from 1 to 8 -instead of from 0 to 7, as they are numbered by linux. I'm stubborn in -this: I know for sure that I wouldn't be able to calculate which port -is which anymore if I would change that.... - - -Devices: - -You should make the device files as follows: - -#!/bin/sh -# (I recommend that you cut-and-paste this into a file and run that) -cd /dev -t=0 -mknod specialix_sxctl c 10 167 -while [ $t -lt 64 ] - do - echo -n "$t " - mknod ttyX$t c 32 $t - mknod cux$t c 33 $t - t=`expr $t + 1` -done -echo "" -rm /etc/psdevtab -ps > /dev/null - - -This creates 64 devices. If you have more, increase the constant on -the line with "while". The devices start at 0, as is customary on -Linux. Specialix seems to like starting the numbering at 1. - -If your system doesn't come with these devices pre-installed, bug your -linux-vendor about this. They should have these devices -"pre-installed" before the new millennium. The "ps" stuff at the end -is to "tell" ps that the new devices exist. - -Officially the maximum number of cards per computer is 4. This driver -however supports as many cards in one machine as you want. You'll run -out of interrupts after a few, but you can switch to polled operation -then. At about 256 ports (More than 8 cards), we run out of minor -device numbers. Sorry. I suggest you buy a second computer....
