Even though the J2240 is not reported to be working yet on the Web pages, it does seem to boot some way. Would anyone have had any success with this machine, or have workarounds to the problems below, or know the work that needs to be done to get this running? Perhaps the following are a clue:

...
dino_bridge_init: IO_ADDR_EN hasn't been configured. kernel BUG at dino.c:795!
...
IRQ not found for serial device at 0xfffffffffc003000
...

#1 lore raw

Hello Douglas,

I have to fess up on this one, since this machine uses both the ccio-dma driver and the 32-bit pdc translator :) I hve been testing on a C200 that uses the ccio-dma driver and the 32-bit translator also ... but I have not been able to boot the machine with a 64-bit kernel yet. I think it is a problem with the ccio-dma driver, but I have been unable to find the error yet.

Booting the machine with a 32-bit kernel should work fine ... if it does not, post the output to the list again we can try to help debug the 32-bit case first. After you boot it witht he 32-bit kernel, you can happily enjoy the 32-bit kernel ... or you can help me find the 64-bit bugs :)

Thanks, and have a good day!

- Ryan

Even though the J2240 is not reported to be working yet on the Web pages, it does seem to boot some way. Would anyone have had any success with this machine, or have workarounds to the problems below, or know the work that needs to be done to get this running? Perhaps the following are a clue:

...

I have to fess up on this one, since this machine uses both the ccio-dma driver and the 32-bit pdc translator :) I hve been testing on a C200 that uses the ccio-dma driver and the 32-bit translator also ... but I have not been able to boot the machine with a 64-bit kernel yet. I think it is a problem with the ccio-dma driver, but I have been unable to find the error yet.

Booting the machine with a 32-bit kernel should work fine ... if it does not, post the output to the list again we can try to help debug

Below is the output for the 32 bit kernel which proceeds in a similar manner to the 64 bit kernel and has the same problems.

#3 lore raw

Douglas,

I glanced through the dino.c code and found the following comment:

/*
** If hversion is what is read from Dino, we should be OK. ** If it's what PDC told us, J2240 PDC reports the hv_model wrong ** for the first Dino. I think it reports 0x05d. <sigh>... **

This comment appears to apply to the bug you are seening since this device shows up in your inventory.

Quoted 2 lines

13. Unknown device (13) at 0xfc000000, versions 0x5d, 0x3, 0xa, 0x0, 0x0 Dino version J2240 (bridge mode) found at 0xfc000000

I will take a look at it some more later today to see if I can figure it out, but Grant Grundler probably already knows how to fix the problem :)

Thanks,

- Ryan

#4 lore raw

Douglas,

I had a chance to chat with Grant, and we have a couple of ideas, but we need some more info first. Grant says the IO_ADDR_EN is supposed to be set by the PDC ... but if no devices exist on the PCI bus below the dino, it is possible the IO_ADDR_EN could be 0. If this is the case, then we need to move the BUG() to a different spot in code.

Grant thinks a possible reason the J2240 crashes is because the rs232 port could both be on the dino and the cujo buses ... and we do not currently support that configuration. I'm not sure if work is being done in that area yet or not ... hopefully someone on this list will pipe up if they are working on it.

I have attached a small patch that will hopefully confirm our thoughts about the IO_ADDR_EN BUG() that I hope you will try out and report back the results. And hopefully someone is working on providing rs232 port support for the dino/cujo busses.

Sorry we do not have a better answer for you.

Douglas,

I glanced through the dino.c code and found the following comment:

/*
** If hversion is what is read from Dino, we should be OK. ** If it's what PDC told us, J2240 PDC reports the hv_model wrong ** for the first Dino. I think it reports 0x05d. <sigh>... **

This comment appears to apply to the bug you are seening since this device shows up in your inventory.

13. Unknown device (13) at 0xfc000000, versions 0x5d, 0x3, 0xa, 0x0, 0x0 Dino version J2240 (bridge mode) found at 0xfc000000

I will take a look at it some more later today to see if I can figure it out, but Grant Grundler probably already knows how to fix the problem :)

Thanks,

- Ryan

I have to fess up on this one, since this machine uses both the ccio-dma driver and the 32-bit pdc translator :) I hve been testing on a C200 that uses the ccio-dma driver and the 32-bit translator also ... but I have not been able to boot the machine with a 64-bit kernel yet. I think it is a problem with the ccio-dma driver, but I have been unable to find the error yet.

Booting the machine with a 32-bit kernel should work fine ... if it does not, post the output to the list again we can try to help debug

Below is the output for the 32 bit kernel which proceeds in a similar manner to the 64 bit kernel and has the same problems.

Regards
Douglas Crosher

Here is the relevant output with you patch applied:

Thanks for looking into it.
