The driver currently - recognises the following chips: - - DC21040 (no SROM) - DC21041[A] - DC21140[A] - DC21142 - DC21143 - - So far the driver is known to work with the following cards: - - KINGSTON - Linksys - ZNYX342 - SMC8432 - SMC9332 (w/new SROM) - ZNYX31[45] - ZNYX346 10/100 4 port (can act as a 10/100 bridge!) - - The driver has been tested on a relatively busy network using the DE425, - DE434, DE435 and DE500 cards and benchmarked with 'ttcp': it transferred - 16M of data to a DECstation 5000/200 as follows: - - TCP UDP - TX RX TX RX - DE425 1030k 997k 1170k 1128k - DE434 1063k 995k 1170k 1125k - DE435 1063k 995k 1170k 1125k - DE500 1063k 998k 1170k 1125k in 10Mb/s mode - - All values are typical (in kBytes/sec) from a sample of 4 for each - measurement. Their error is +/-20k on a quiet (private) network and also - depend on what load the CPU has. - - ========================================================================= - This driver has been written substantially from scratch, although its - inheritance of style and stack interface from 'ewrk3.c' and in turn from - Donald Becker's 'lance.c' should be obvious. With the module autoload of - every usable DECchip board, I pinched Donald's 'next_module' field to - link my modules together. - - Up to 15 EISA cards can be supported under this driver, limited primarily - by the available IRQ lines. I have checked different configurations of - multiple depca, EtherWORKS 3 cards and de4x5 cards and have not found a - problem yet (provided you have at least depca.c v0.38) ... - - PCI support has been added to allow the driver to work with the DE434, - DE435, DE450 and DE500 cards. The I/O accesses are a bit of a kludge due - to the differences in the EISA and PCI CSR address offsets from the base - address. - - The ability to load this driver as a loadable module has been included - and used extensively during the driver development (to save those long - reboot sequences). Loadable module support under PCI and EISA has been - achieved by letting the driver autoprobe as if it were compiled into the - kernel. Do make sure you're not sharing interrupts with anything that - cannot accommodate interrupt sharing! - - To utilise this ability, you have to do 8 things: - - 0) have a copy of the loadable modules code installed on your system. - 1) copy de4x5.c from the /linux/drivers/net directory to your favourite - temporary directory. - 2) for fixed autoprobes (not recommended), edit the source code near - line 5594 to reflect the I/O address you're using, or assign these when - loading by: - - insmod de4x5 io=0xghh where g = bus number - hh = device number - - NB: autoprobing for modules is now supported by default. You may just - use: - - insmod de4x5 - - to load all available boards. For a specific board, still use - the 'io=?' above. - 3) compile de4x5.c, but include -DMODULE in the command line to ensure - that the correct bits are compiled (see end of source code). - 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a - kernel with the de4x5 configuration turned off and reboot. - 5) insmod de4x5 [io=0xghh] - 6) run the net startup bits for your new eth?? interface(s) manually - (usually /etc/rc.inet[12] at boot time). - 7) enjoy! - - To unload a module, turn off the associated interface(s) - 'ifconfig eth?? down' then 'rmmod de4x5'. - - Automedia detection is included so that in principal you can disconnect - from, e.g. TP, reconnect to BNC and things will still work (after a - pause whilst the driver figures out where its media went). My tests - using ping showed that it appears to work.... - - By default, the driver will now autodetect any DECchip based card. - Should you have a need to restrict the driver to DIGITAL only cards, you - can compile with a DEC_ONLY define, or if loading as a module, use the - 'dec_only=1' parameter. - - I've changed the timing routines to use the kernel timer and scheduling - functions so that the hangs and other assorted problems that occurred - while autosensing the media should be gone. A bonus for the DC21040 - auto media sense algorithm is that it can now use one that is more in - line with the rest (the DC21040 chip doesn't have a hardware timer). - The downside is the 1 'jiffies' (10ms) resolution. - - IEEE 802.3u MII interface code has been added in anticipation that some - products may use it in the future. - - The SMC9332 card has a non-compliant SROM which needs fixing - I have - patched this driver to detect it because the SROM format used complies - to a previous DEC-STD format. - - I have removed the buffer copies needed for receive on Intels. I cannot - remove them for Alphas since the Tulip hardware only does longword - aligned DMA transfers and the Alphas get alignment traps with non - longword aligned data copies (which makes them really slow). No comment. - - I have added SROM decoding routines to make this driver work with any - card that supports the Digital Semiconductor SROM spec. This will help - all cards running the dc2114x series chips in particular. Cards using - the dc2104x chips should run correctly with the basic driver. I'm in - debt to <mjacob@feral.com> for the testing and feedback that helped get - this feature working. So far we have tested KINGSTON, SMC8432, SMC9332 - (with the latest SROM complying with the SROM spec V3: their first was - broken), ZNYX342 and LinkSys. ZYNX314 (dual 21041 MAC) and ZNYX 315 - (quad 21041 MAC) cards also appear to work despite their incorrectly - wired IRQs. - - I have added a temporary fix for interrupt problems when some SCSI cards - share the same interrupt as the DECchip based cards. The problem occurs - because the SCSI card wants to grab the interrupt as a fast interrupt - (runs the service routine with interrupts turned off) vs. this card - which really needs to run the service routine with interrupts turned on. - This driver will now add the interrupt service routine as a fast - interrupt if it is bounced from the slow interrupt. THIS IS NOT A - RECOMMENDED WAY TO RUN THE DRIVER and has been done for a limited time - until people sort out their compatibility issues and the kernel - interrupt service code is fixed. YOU SHOULD SEPARATE OUT THE FAST - INTERRUPT CARDS FROM THE SLOW INTERRUPT CARDS to ensure that they do not - run on the same interrupt. PCMCIA/CardBus is another can of worms... - - Finally, I think I have really fixed the module loading problem with - more than one DECchip based card. As a side effect, I don't mess with - the device structure any more which means that if more than 1 card in - 2.0.x is installed (4 in 2.1.x), the user will have to edit - linux/drivers/net/Space.c to make room for them. Hence, module loading - is the preferred way to use this driver, since it doesn't have this - limitation. - - Where SROM media detection is used and full duplex is specified in the - SROM, the feature is ignored unless lp->params.fdx is set at compile - time OR during a module load (insmod de4x5 args='eth??:fdx' [see - below]). This is because there is no way to automatically detect full - duplex links except through autonegotiation. When I include the - autonegotiation feature in the SROM autoconf code, this detection will - occur automatically for that case. - - Command line arguments are now allowed, similar to passing arguments - through LILO. This will allow a per adapter board set up of full duplex - and media. The only lexical constraints are: the board name (dev->name) - appears in the list before its parameters. The list of parameters ends - either at the end of the parameter list or with another board name. The - following parameters are allowed: - - fdx for full duplex - autosense to set the media/speed; with the following - sub-parameters: - TP, TP_NW, BNC, AUI, BNC_AUI, 100Mb, 10Mb, AUTO - - Case sensitivity is important for the sub-parameters. They *must* be - upper case. Examples: - - insmod de4x5 args='eth1:fdx autosense=BNC eth0:autosense=100Mb'. - - For a compiled in driver, at or above line 548, place e.g. - #define DE4X5_PARM "eth0:fdx autosense=AUI eth2:autosense=TP" - - Yes, I know full duplex isn't permissible on BNC or AUI; they're just - examples. By default, full duplex is turned off and AUTO is the default - autosense setting. In reality, I expect only the full duplex option to - be used. Note the use of single quotes in the two examples above and the - lack of commas to separate items. ALSO, you must get the requested media - correct in relation to what the adapter SROM says it has. There's no way - to determine this in advance other than by trial and error and common - sense, e.g. call a BNC connectored port 'BNC', not '10Mb'. - - Changed the bus probing. EISA used to be done first, followed by PCI. - Most people probably don't even know what a de425 is today and the EISA - probe has messed up some SCSI cards in the past, so now PCI is always - probed first followed by EISA if a) the architecture allows EISA and - either b) there have been no PCI cards detected or c) an EISA probe is - forced by the user. To force a probe include "force_eisa" in your - insmod "args" line; for built-in kernels either change the driver to do - this automatically or include #define DE4X5_FORCE_EISA on or before - line 1040 in the driver. - - TO DO: - ------ - - Revision History - ---------------- - - Version Date Description - - 0.1 17-Nov-94 Initial writing.
