Hi Krzysztof,

Systems with the old chip probably report the device with a single
PNP ID.  For PNPBIOS, that would be the "device product identifier."
For ACPI, it would be the _HID.

Systems with the new chip should report both PNP IDs.  The PNPBIOS
device product identifier or the ACPI _HID should be the new ID, and
the older ID for backward compatibility should be reported in the
PNPBIOS "compatible device identifiers" list or the ACPI _CID.

The driver would list both IDs in the pnp_device_id table, and it
looks like the driver probe routine gets called with the ID that
matched.

I don't see any drivers that actually do this, but I think the
probe routine should be able to look at the ID that matched and
determine whether the additional I/O range is present.

Oops, looking at match_device() in drivers/pnp/driver.c, I think
we look at all the device IDs supported by the driver, but we only
look at the first ID associated with the device.  That means an old
driver that only knows about the old device ID would fail to claim
a new device (the new device will have the new ID first and old IDs
in the compatibility list).  That looks like a bug in the PNP core --
the old driver should be able to claim any new compatible devices.

Let me know if you think you're seeing this bug, and I'll look into
it some more.

The laptop in question is the Dell Latitude CPi and it does not
have ACPI only the PnP BIOS. 
The both ids are reported as unrelated (two separate nodes in 
the /sys/bus/pnp/). I don't know how to set up the "compatible device 
identifiers" list. It is not defined in the include/linux/pnp.h.
If I know that I will test this.

Currently, I iterate over pnpbios_protocol to find out if the second 
id exists. It is not elegant but works.

Oh.  That sounds like a BIOS bug.  If there's only one actual
chip, the BIOS should not report it as two separate devices.
I guess it might report two devices if only one of them is
enabled at a time.  In that case, there might be a BIOS setup
switch to toggle between them.

Can you turn on CONFIG_PNP_DEBUG_MESSAGES and boot with the
pnp.debug kernel parameter?  Then collect the dmesg log and
the output of "grep . /sys/devices/pnp*/*/*".

The compatible device identifiers list is built by the kernel
based on the information from the BIOS.  Drivers don't have to
worry about it.

Can you point me to the driver?

If this is a BIOS defect, we might be able to write a quirk to work
around it so the driver doesn't have to get messy.

If it is the BIOS bug it is pretty widespread. At least, the same 
chip in IBM laptops have the same problem. Desktop Dell models
have the problem as well. I suspect this is how a MS Windows 
driver expects this chip.

I did the "grep . /sys/bus/pnp/*/*". The chip in question has the ids 00:0f
and 00:10. The grep log is at the end of the email.

The driver in question is snd-cs4232 and snd-cs4236. The change has
been posted here 

http://mailman.alsa-project.org/pipermail/alsa-devel/2009-January/014226.html

The iteration part is here:

+static int __devinit snd_cs423x_pnpbios_detect(struct pnp_dev *pdev,
 					       const struct pnp_device_id *id)
 {
 	static int dev;
 	int err;
 	struct snd_card *card;
+	struct pnp_dev *cdev;
+	struct list_head *pos;
+	char cid[PNP_ID_LEN];
 
 	if (pnp_device_is_isapnp(pdev))
 		return -ENOENT;	/* we have another procedure - card */
@@ -594,10 +575,20 @@ static int __devinit snd_cs4232_pnpbios_detect(struct pnp_dev *pdev,
 	if (dev >= SNDRV_CARDS)
 		return -ENODEV;
 
+	/* prepare second id */
+	strcpy(cid, pdev->id[0].id);
+	cid[5] = '1';
+	cdev = NULL;
+	list_for_each(pos, &(pdev->protocol->devices)) {
+		cdev = list_entry(pos, struct pnp_dev, protocol_list);
+		if (!strcmp(cdev->id[0].id, cid))
+			break;
+	}

If the cdev is not NULL after the loop it means that the chip is later 
model with additional ports. It is not very messy.

I asked because I thought maybe there is a simpler or cleaner way
which I am not aware of.

It's not a bug. The cs423x chips contain several logical devices.
WSS, MPU401, joystick etc. The control logical device (which is
not present in the early models) is unfortunately some kind of dumping
ground for new registers to keep the other logical devices' backwards
compatible. It contains at least some extra mixer control registers and
power management registers.

The datasheets are available at ftp.alsa-project.org.

Sorry it took me so long to get back to this.

Yes, you're right.  I was thinking the first device had a set of
resources, and the second device had a superset that included the
same resources plus another one, but that's not the case here.

In this case, you have:

  /sys/bus/pnp/devices/00:0f/id:CSC0000
  /sys/bus/pnp/devices/00:0f/resources:state = active
  /sys/bus/pnp/devices/00:0f/resources:io 0x530-0x537
  /sys/bus/pnp/devices/00:0f/resources:io 0x388-0x38b
  /sys/bus/pnp/devices/00:0f/resources:io 0x220-0x22f
  /sys/bus/pnp/devices/00:0f/resources:irq 5
  /sys/bus/pnp/devices/00:0f/resources:dma 1
  /sys/bus/pnp/devices/00:0f/resources:dma 0

  /sys/bus/pnp/devices/00:10/id:CSC0010
  /sys/bus/pnp/devices/00:10/resources:state = active
  /sys/bus/pnp/devices/00:10/resources:io 0x210-0x217

Can't you just register another struct pnp_driver that claims the
CSC0010 device?  E.g., something like:

  static struct pnp_dev *ctrl;
  static int snd_cs423x_ctrl_pnpbios_detect(struct pnp_dev *dev, ...)
  {
	if (pnp_device_is_isapnp(dev)
		return -ENOENT;
	ctrl = dev;
	return 0;
  }

  static const struct pnp_device_id snd_cs423x_ctrl_ids[] = {
	{ .id = "CSC0010" },
  };
  static struct pnp_driver cs423x_ctrl_pnp_driver = {
	.id_table = snd_cs423x_ctrl_ids,
	.probe = snd_cs423x_ctrl_pnpbios_detect,
  };

Obviously that doesn't work for multiple cs423x chips, but I think we
had that problem before.  For ISAPNP, we have the "card" concept to
group the related logical devices.  But I don't see anything similar
in PNPBIOS (maybe I missed it), so I don't see how we could keep track
of multiple PNPBIOS cs423x chips.
