Re: Driver help
Yes, well, there is something Linux called the Compaq Fibre Channel Driver, and it's not QLogic based- nor is it Emulex based- I believe it's Tachyon- lite.

Re: Driver help
dumb is relative and fungible. It's a tradeoff between doing the connection management in firmware (as with the QLogic) or in the Kernel (as with Tachyon products mostly). It depends on whom you believe ultimately does a better job. Doing it in firmware allows the driver writer to manage the ULP stuff a lot better because you're not so distracted by the low level ruckus. Doing it in the kernel allows you to avoid all those nagging and persistent questions of why the hell did the f/w do/say/barfturn-left-against-a-red *that*? -matt On Wed, 31 Oct 2001, Wilko Bulte wrote: On Wed, Oct 31, 2001 at 09:49:19AM -0800, Matthew Jacob wrote: That is probably what we call the Jaguar in-house.

I'm personally a firm believer in having the card do the work so as to avoid the unnecessary bus transfers from the kernel doing the work. Alfred and Eric Melville both have incredibly funny anecdotes about Windows machines without GL accelerators configured as servers, and with GL screen savers which eat most of the CPU away from server applications... -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

It's a tradeoff between doing the connection management in firmware (as with the QLogic) or in the Kernel (as with Tachyon products mostly). It depends on whom you believe ultimately does a better job. Well, I generally would like to put my money on the firmware. This assumes (as always..) good firmware.

But it tends to produce horrible drivers if you are not very careful. I remember a WD33C93 driver here.. shiver On Wed, 31 Oct 2001, Wilko Bulte wrote: On Wed, Oct 31, 2001 at 09:49:19AM -0800, Matthew Jacob wrote: That is probably what we call the Jaguar in-house.

ISA LM78 driver help
Hello there... I have an application where I require access to an LM78 health monitor chip on a certain type of industrial PC motherboard we use. Unfortunately, the LM78 is tied to ISA and not I2C/SMBus. Can anyone recommend a good framework to start writing a driver for this beastie? I've never actually written a driver before (*gulp*), so please treat me gently ;-) In essense, the chip sits at 0x290 with an address line at 0x290+5 and a data line at 0x290+6. I'd be happy writing a program that merely peeks and pokes in that address area, rather than a fully-fledged driver...
