Very Computer

by **Manuel Serran** » Tue, 05 Nov 2002 13:10:12

Hello there,

I'm trying to install Linux on a Sony PCG-C1MHP (a Picturebook, which
are those very small computer equiped with Crusoe processor). Basically
I have a Debian running on this platform but I still have 5 problems.

I don't know exactly which is the best way to submit these bug reports
and to whom I should send the mails. For instance, I have found very little
support from Transmeta for running Linux on this computer. Please, feel
free to tell me who I should send these mails to and please feel free to
forward these mails to the one you think are the correct persons.

First of all, I'm not familiar with kernel development. I don't even
know precisely how an OS kernel such as the Linux kernel works. So, I
apologize if I report incomplete or erroneous information. I will try
my best and of course:
- I will be very happy to report for precise information.
- I'm willing to help, as much as I can.

I will send 5 of these mails, each reporting about one problem. Here is
the first one, which is the most annoying one.

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

[1.] One line summary of the problem:
=====================================

The DMA support cannot be enabled for the harddisk

[2.] Full description of the problem/report:
============================================

As far as I have understood, this computer uses an ALi M1533 chip for
controling the disk (even though, I must admit that I'm totally confused
between the reference "ALi M1533 PCI to ISA Bridge" and the
reference "ALi M5229 IDE"). If I compile the kernel (version 2.4.18, 2.4.19,
2.4.20-pre10, and 2.4.20-rc1) enabling the M15x3 support, I always have the
same problem: the machine does not boot. I can't send the actual error message
because the machine hangs without logging any message. However, I got
something that ends with a message such as:

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----
ALI15X3: chipset revision 196
ALI15X3: IDE controller on PCI bus 00 dev 80
ALI15X3: not 100% native mode: will probe irqs later
-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

Nothing more. At this point, the keyboard is ineffective. The only solution
is to switch off the computer.

On the web site: http://hale.org/~bhoward/issue_7/pcg-c1mrx.html,
Bruce Howard reports a bug in the alim15x3.c kernel. I have tried to apply
his patch but this does not help. He also mention to boot the kernel with
the flags "ide2=0x180,0x386 pci=conf2". I don't think I understand the
meaning of these flags but what I'm sure about is that they don't help.

In conclusion, the only way I have to boot the machine is using the generic
IDE controler that works fine excepts that it does not support DMA for the
disk. In consequence, I have very poor disk performance.

Many thanks, in advance, for your help.

Should be fixed in the development tree already. Forcing ata66 might
also make the problem go away. The ALi code in the existing kernels
assumes ALi north and south bridges so comes apart completely on the
crusoe boxes which have a transmeta virtual northbridge on the
CPU/software itself.

I'm sorry to keep bothering all of you with this problem. I have tried
a new version of the kernel (2.4.20-pre10-ac2) and I'm afraid that it does
not fix the problem. I'm now able to compile and boot a kernel using the
specific IDE driver but I'm still enable to enable the DMA on the disk.

Here are the information I have a boot-time:

This is all useful info

You hit one of the other bugs the -ac code introduced - whoops. This one
is the main reason I've not yet pushed it to Marcelo. I still have to
fix the probing code so that we don't make a decision based upon what
drives are present before probing the drives

Hello there,

I'm just trying the new kernel version from the ac serie. That is, I'm trying
to compile 2.4.20-rc1-ac3 on my Vaio platform.

I have the impression that there is a problem in the kernel compilation:

Hello there,

First of all, I apologize for multiple copies. We have big troubles
with our local network and I have lost halt of my outgoing mails. I
have looked at the mailing list archive to check if my mail of yesterday
has reached the mailing and I have the impression that it has been
lost. So I re-post it today.

I have tried the new version of the 2.4-ac brand of Linux kernel on my
Sony Vaio PictureBook (equipped with a crusoe processor). That is,
have tried 2.4.20-rc1-ac4. This version compiles but at boot time
have a kernel panic. Here is a trace of the error (I apologize for the
typo, I have typed-in what was displayed on the screen).

I hope this mail will help. Many thanks for your help and for your work.
Very sincerely,

ps: Just for the information, I included here a previous mail I have sent,
describing the problem I have with the main distribution of the kernel.
