Current work
We're still having a problem with media selection and interrupts on A180, and endianness problems on 21140 chipset PCI cards. Thomas made good progress with a pcnet32 card with endian clean driver, exposing bugs in the tcp checksum code which have been largely fixed. Thomas expects to have tulip working by this weekend. Lack of endianess support is the main problem. 2.2.14 is the "latest" tulip.c but has no big endian support. Mike Ang will send the outputs of the tulip diagnostic program in cvsroot:/userspace/ktulip-diag.c to Donald Becker for help.
SuperIO serial
SuperIO serial support is required to get userland serial console working on C3000. Martin Petersen looked at data sheet and it's way too complicated. Grant Grundler: I think the various components have to share IRQ lines. Since this bugger is 3 PCI functions and only function 1 (or 2) has the IRQ line, it gets a bit messy. I think we also need to get some specifics on how firmware *reports* those devices. I helped set some of that up for HP-UX but that was over a year ago. IIRC, the function 0 gets advertised first to HP-UX but it's interrupt comes through function 1. So the driver for function 0 has to poke registers on function 1. Grant - will check if anyone in HP is interested in making this work. Mike volunteered to start looking at it on Monday (2/7/2000).
Interrupts on C3000
Grant Still working on it. Fleed is still having/had trouble with card-mode dino. dino.c.ilr data page faulted. Grant will look at this after spending some more time on C3k problems.
Willy mentioned that we will have to think about running on 64bit at some point.
Short term goals
(roughly in order)
serial console input and output
nfs root filesystem
scsi support
