PCMCIA on a Pismo with pcmcia-cs-3.1.24

PCMCIA on a Pismo with pcmcia-cs-3.1.24

[Michael K. Fleming]

Hi--

I'm trying to get PCMCIA working on my Mac Powerbook Pismo, with kernel
2.2.18pre4-ben1 and pcmcia-cs-3.1.24 (no patches applied--as far as I can
tell, none should be necessary...).  I'm primarily trying to get a
WaveLAN card to work.

I've carefully read the notes at:

http://www.mpifr-bonn.mpg.de/div/iri/Archiv/LinuxPPC/PCMCIA.html

and followed what seemed currently relevant.

The problem seems to be that the i82365 driver cannot properly allocate
the interrupt assigned to the device.  The problem I'm having seems to be
identical to one that Uwe Steinmann reported a few weeks ago on this
mailing list.  I've read the followups to that email, but did not find any
solutions.

The relevant portions of my kernel log, /etc/pcmcia/config.opts, and lspci
are attached below.

Any hints or pointers would be greatly appreciated.

This should be your problem... If you have a Pismo, you can not boot with BootX,
and in this case you have to patch your kernel. Did not check 2.2.18 yet (yeah,
my web page is outdated...), but I guess it is still necessary...

Hope this helps, Albrecht.

This leads to a complete failure of the pcmcia package...

Looks fine.

These entries look suspicious, and they do not work for sure with our pismos.

These are correct for a 2.2 kernel. 2.4 will have something like
primary=01, secondary=02, ...

The working config on the Lombard is

00:13.0 CardBus bridge: Texas Instruments PCI1211
	[...]
        Bus: primary=00, secondary=01, subordinate=04, sec-latency=176

and on the Pismo

00:1a.0 CardBus bridge: Texas Instruments PCI1211
	[...]
        Bus: primary=00, secondary=01, subordinate=04, sec-latency=32

These are the same bus settings as with MacOS, but I must admit that I do not
know exactly what they are for... The default values with the unpatched kernel
if booting with yaboot do not work at all, at least with the 2.2.x series.

I'm not booting with BootX--I'm booting with yaboot.

What patches do I have to apply to my kernel?  Or do you mean patches to
pcmcia-cs?

If you boot with BootX (which you *can* *not* use with the Pismo), OpenFirmware
takes care that the CardBus Bridge is initialised properly (but the kernel still
get a wrong number of pci busses on the Wallstreet/Lombard...). If you boot with
yaboot, some registers in the bridge contain bad values. I tried the stock
LinuxPPC 2.2.18 sources a few days ago, and they *still* need the patch. I did
not try the kernel-pmac rpm though, but if your box does not detect the IRQ,
there is no other solution than building a new kernel.

You just have to patch your kernel sources, as decsribed on my web page (see
http://www.mpifr-bonn.mpg.de/div/iri/Archiv/LinuxPPC/PCMCIA.html, just follow
the instructions in the section "Kernel Setup").

It *might* be possible for you to use the kernel-pcmcia-cs-2.2.18-4h.ppc.rpm
package. If it does not work, you should build your own pcmcia stuff. As pointed
out in the "PCMCIA/CardBus" section of the web page mentioned above, on the
Pismo you should use the stock package from sourceforge *without* any additional
patches. You *must* change the pcmcia config files afterwards, though.

Hth,

	Albrecht.
