Hi, I am seeking feedback in regards to issues with a ExpressCard/54 audio card (http://www.notebookreview.com/notebookreview/creative-soundblaster-x-fi-xtreme-audio-for-notebook-review/) under Linux (same card has been working fine in Win 7). After recently having a conversation on alsa-devel about it, it was decided it seems to be a PCI issue. The "devices" in question....
Hi Alnie,

I've tried many kernels from 2.6 to 3.18 with similar results. Willing to retrieve more info. Thank you :)
It looks like you booted with the card already installed, then removed
and reinstalled it. Did the card work at any point? If it worked
before the hotplug, then we need to look for a hotplug problem. If it
never worked, then we can ignore hotplug for now.
My guess is that the card never worked at all and hotplug isn't an issue here.
Correct. The card has not worked at any point for me in Linux.
The pciehp messages above are a bit scary looking, but I don't think
they actually show a problem. It looks like you booted with the
ExpressCard present, and it was configured like this:
pci 0000:00:1c.3: PCI bridge to [bus 05-0c]
pci 0000:00:1c.3: bridge window [io 0x2000-0x2fff]

PwrCtrl- MRL- Interlock- NoCompl- LLActRep+
The kernel didn't change anything on the device, but the driver complained:
snd_hda_intel 0000:06:00.0: Codec #1 probe error; disabling it...
snd_hda_intel 0000:06:00.0: no AFG or MFG node found
snd_hda_intel 0000:06:00.0: no codecs initialized
I assume the device is not working at this point. (Correct me if I'm
wrong.) Some time later, at timestamp 2620, it looks like you
unplugged and replugged the ExpressCard. We reconfigured the bridge
and device like this:
pci 0000:05:00.0: PCI bridge to [bus 06]
pci 0000:05:00.0: bridge window [io 0x2000-0x2fff]
pci 0000:05:00.0: bridge window [mem 0xf4300000-0xf43fffff]
pci 0000:05:00.0: bridge window [mem 0xf4000000-0xf40fffff 64bit pref]
pci 0000:06:00.0: BAR 0: assigned [mem 0xf4300000-0xf4303fff]
This is slightly different than what we had initially:
- 05:00.0 bridge bus aperture is [bus 06] instead of [bus 06-0c]
- 05:00.0 bridge io aperture is enabled instead of disabled
- 05:00.0 bridge mem pref aperture is enabled instead of disabled
But none of these is a problem and the audio device itself at 06:00.0
is programmed identically to what we had initially. And it looks like
the driver complains exactly the same way it did at boot-time. So I
don't think this is related to hotplug.
Can you use a program like this:
http://cmp.felk.cvut.cz/~pisa/linux/rdwrmem.c to read some of the
device registers, e.g., the ones mapped by BAR 0 at 0xf4300000? I
don't know what the register layout is, but if you get all 0xff
responses, that might indicate that the device isn't responding,
either because we haven't enabled it correctly or we haven't routed
that space correctly, or .... If you get any data that is NOT all
ones, that means the device is responding.
I just compiled this but I'm a bit unfamiliar, sorry :( It is giving me
"mmap error". Is this the what you are looking for?
./mem -N -m -s 0xf4000000
./mem: request seek to 4093640704, but -201326592 returned
F4000000:FF
Could you also collect the output of "lspci -vvs00:1c.3"
