There is ')' missing around if() in this file.

Like I said, totally untested, all I did was write it and upload it. I have no Pegasos here so I see no point in wasting time building a kernel when everyone who has been affected by the bug has been building kernels anyway :D

Anyway tested with finak 2.6.22 and as expected both irq's are set to 14, but I am affraid this doesn't help with my problem with ATAPI device and I still can see timeout errors on boot :( Same as previous.

Can you take those errors to the Linux-IDE list and throw them past Tejun and Alan? As far as I am concerned and after studying all my previous notes on the IDE fix, to fit PCI mode properly this is the only, single change that needs making, so maybe something else is wrong.

Tejun also put out some patches which may also help (or hinder) the fixup.

*nudges tj*

Perhaps there is something missing from the fixup. Maybe we need to nudge the IDE controller and do a software reset or something, but libata should be doing that anyway. I dunno. Can you get to a shell and see if pata_via has reserved any resources (io memory etc.) which may be in the wrong places?

This output was created using 2.6.22-RC4. The latest factory arrived to mirrors finally this morning, so I just finished installation. Will test it also on 2.6.22-RC7...

http://www.powerdeveloper.org/files/Peg ... fixup.diff

Changes since yesterday;

Anyone who tried it yesterday and got interrupt 0, or interrupt 14 but timeouts, the native interrupt routing mode should fix it.

I am also VERY interested in whether the original via86cxxx block driver works with this patch (remove the #if's and take out the Pegasos hack from that driver). If it does, then we can remove the weird Pegasos hack from there and move it into platform support.

Thanks guys

OK, it works now. I made a couple of rounds around it, as I assumed, that mkinitrd on openSUSE loads all the necessary modules. Now tested with everything compiled in, and that works. Compiling it now again leaving everything as modules and fix up mkinitrd configuration...

It still says irq 0? I think that is a summary of the problems with the timeout, but why? :(

I still suffer from the timeout problems. Anyway I have here a serial console then if you need aditional informations add required debug to kernel and send me a diff. I will be happy to check/send results for you.

Did you also modify prom_init.c? Info for that was well hidden in yesterdays patch :) Today it seems to be included, and in a patch instead of needing to paste some text file to the end of a file.

I also had the problem, that openSUSE's mkinitrd did not load the necessary modules to use libata. When I compiled everything in, it worked fine. (libata, pata_via, scsi, scsi hdd). I'm just trying to build all of these as modules...

You know it may be easier if you go find the VT8231 datasheet and start hacking around yourself.

I'd suggest removing the part that sets IRQ steering (top read/write pair) since in theory it is not necessary. Maybe I should poke 14 into the interrupt line, too, maybe it's being reset..?

Since I have no Pegasos here I am relying on other people to try the patch. The information in the dmesg even with debug output would be very low.. there is not much more information you can print out. All I can confirm is, that since it says it is fixing the problem in CzP's dmesg, then dev->irq is actually 14 which means you should get 14 back from libata.

Anyway. This should have been a fix of 5 minutes and now I have been playing with it for 5 days straight and been concerned about it for over a year.

Looking a bit more carefully at dmesg reveals, that only the primary IDE is working. Secondary is found:

Code:

ata2.00: ATAPI: SAMSUNG CDRW/DVD SM-352N, TA00, max UDMA/33
ata2.00: configured for UDMA/33

but it does not work, as all the timeout messages belong to there.

Still, it's a lot better, than nothing. With some re-cabling, an installation should work with HD as primary master and CD as slave on the same cable.

BTW: tested, pata_via works now nicely as module. Will test the old driver next..

So basically the same as we always thought; sharing interrupts for the secondary channel seems broken on the VT8231. Whether that is our fault or driver fault, I don't know, but many people must be running the Via IDE in native interrupt mode..

I think if we cannot resolve a way to fix this up it will HAVE to be a libata improvement. At least we are proving to the libata guys that, this is not a Pegasos problem, but weird Via chipset problem, and we could find some pata_via dedicated fix which handles such strange configurations (native IO with legacy interrupts).

I am also VERY interested in whether the original via86cxxx block driver works with this patch (remove the #if's and take out the Pegasos hack from that driver). If it does, then we can remove the weird Pegasos hack from there and move it into platform support.

Hello,

* In the patch, you need to update pdev->class too after updating the actual register.

* printing 0 as irq was a bug in libata fixed recently. 2.6.22 should print the proper irq line number.

* Dunno about the specific chipset but via PATAs usually work fine in native mode.

* In the error message, ata2.00 timesout requests to configure udma/33 but gets successfully configured for udma/25. I wonder it's drive-specific problem. Can you put another device at the secondary channel and test?

Thanks.

The same drive works fine with an unmodified old IDE driver, so it's probably not a hw problem. None the less, I'll try to find another drive when I next go to Budapest, as it's the only one here.
