[matthieu castet]

Hi,

I had also done a pnp patch for the smsc-ircc2 and irport 3 months ago.
Unfortunaly I don't remember where I put the patches, certainly on the 
laptop that it is in my parent home.

It will reenable the device.

Yes that's the problem this pnp, if the probe failed it disable the 
device resource.
When I do my patch I encounter the problem : I called pnp driver after 
smsc_ircc_look_for_chips, so all the resources where already reserved, 
and the pnp probe failed and it disable the resource, and the device 
found with the traditional smsc_ircc_look_for_chips doesn't work.

So in my patch if I register pnp devices, I don't run 
smsc_ircc_look_for_chips like it is done for (ircc_fir>0)&&(ircc_sir>0) 
case.

pnp should call automatiquely pnp_activate_dev() before probing the 
driver, so the resource should be activated. Have you got an example 
where the resource wheren't activated ?

	smsc_ircc_look_for_chips won't re-register the devices
configured via PnP, as smsc_ircc_present won't be able to request the
region. So, I don't see the problem. And you could imagine having
multiple SMSC in the box, some PnP, some not.
	Note that we could put the region check earlier, but I like
the fact that the driver is still able to probe completely the chip
even if the serial driver has grabbed the regions. Maybe we could
split the difference and request the FIR region early on (so to fail
on SMC devices already registered) and request the other ressources
late (so as to completely probe even when serial is loaded).

	No, it was more that I don't understand what PnP does for
us. I don't have a SMS chipset to test on. Also, I would like to know
if it remove the need of smcinit.

	Thanks, have fun...

if you are still interested for the irport, I could try to ask someone

Yes, it was just because it produce some warning message.

PnP is easy to understand ;)
When you probe a device, it will activate a device with the best 
configuration available.
When removing a device it will disable the resource of the device.
A driver could play a little with the resources configuration : try 
another configuration, but it is not really need.

Also PnP can provide several id for a device : for example for my smsc 
device, I have SMCf010 and PNP0510 or PNP0511. So in this case we should 
load the smsc driver first, otherwise for example a pnp version of 
irport could register the device and it is not available for smsc (PnP 
will see that there is a driver attached, and not give it to the smsc 
probe).

So can we just remove the IORESOURCE_DISABLED tests?

And what about the pnp_*_valid() tests?

parport_pc (which I used as a guide) does both tests but 8250_pnp doesn't 
do either.

Parport_pc uses them because resources could potentially be disabled, but the
parport could still be functional.  Therefore, it must check.  It is probably
ok to not check on most hardware.  Nonetheless, it's best to play it safe, and
always verify the resource configuration.

I tried this on my Toshiba Satellite 1800-314 and the device gets IO
resources but is still disabled. echo activate > ... will enable it but
the smc-ircc2 driver still finds that the device is disabled (in

Looks like there is also a enable/disable bit in the actual LPC device,
or maybe it needs also a fir address and/or irq?

that's very strange : you must have 2 io entries, 1 dma entry and an irq 
entry.
Could you try pnpacpi from mm series ?
Any warning from pnpbios at startup ?
A laptop of the friend have wrong pnpbios entries...

Also make sure you don't force in your bios the device to be a sir device.

no need : it is in rc2.
So do you use pnpacpi ?
If so, could you send your dsdt and try with pnpbios?

hum, your bios seem to build dynamically the resources (need an acpi

Could it be an acpi parsing problem ?
Is there a easy way to use ACPI_DUMP_RESOURCE_LIST in order to find all 
the resource find by acpi in order to see if it is an acpi problem or a 
pnpacpi problem ?

Could you try this patch with pnpacpi?

Yes, it gives full options (and resources after "auto"). But smsc-ircc2 
still does not load even after "activate" with pnpacpi. It loads with 
pnpbios after auto and activate.

Could I have the log from smsc-ircc2 when it failed with pnpacpi ?

Thanks, it seem that pnpacpi_set_resources have a problem.
I hope Shaohua Li (who write it) could ckeck it.

smsc patch?

It sould find the correct resources because there are provided by PnP 
layer, but if the resources are not well allocated by PnPacpi, the 
device shouldn't work.

Could you please attach the output of 'cat 00:0a/resources' (0a is the
device, right?). ACPI spec said set resource should be according to the
output of current resource. That is we should build a template according
to current resource (_CRS). If _CRS doesn't return a correct resource
templete, set resource will fail.

Adam, I think a boot option (such as pnpacpi=off) is required. Users
possibly want to use pnpbios or BIOS is buggy.

Thanks,
Shaohua

resources after auto and activate and options are now exactly the same 
after the pnpacpi patch:

resources:

state = active
io 0x100-0x107
io 0x2e8-0x2ef
irq 5
dma 3

options:

port 0x100-0x130, align 0xf, size 0x8, 16-bit address decoding
irq 3,4,5,7,10,11 High-Edge
dma 1,2,3 16-bit compatible
Dependent: 01 - Priority acceptable
    port 0x3f8-0x3f8, align 0x0, size 0x8, 16-bit address decoding
Dependent: 02 - Priority acceptable
    port 0x2e8-0x2e8, align 0x0, size 0x8, 16-bit address decoding
Dependent: 03 - Priority acceptable
    port 0x2f8-0x2f8, align 0x0, size 0x8, 16-bit address decoding
Dependent: 04 - Priority acceptable
    port 0x3e8-0x3e8, align 0x0, size 0x8, 16-bit address decoding

Hi,

could you try this patch with the previous one. (You must enable ACPI 
DEBUG in kernel config)

When you activate the device, it sould print usefull information.
Could attach the output, please.

After fixing one res -> resource, it compiled.

The output is uninteresting - it only prints one debug message during 
echoing activate to resources:

******845*******

Oups that's the wrong fix : there was a line missing in my previous patch

That's because resource point at the end of the resources list, so there 
is nothing to read. With this patch, you should see something.

On bootup there are loads on lines 167 and 472.

On auto there are none.

On activate there are
******846*******
pnp: Device 00:0a activated.

On modprobe smsc-ircc2 there are no more debug lines, just
found SMC SuperIO Chip (devid=0x5a rev=00 base=0x002e): LPC47N227

thanks.
it seems there is no resource in your __CRS. Like Shaohua said the acpi 
spec say that it must return valid template even if the device is 
disable [1].

Just for confirmation, could you try this patch. It should enable 
pnp_dbg message and print your _CRS when you activate the device.
If there is nothing between ******574******* and ******857*******, you 
bios is likely broken.


thanks

Matthieu CASTET



[1]
If a device is disabled, then _CRS returns a valid resource template for 
the device, but the actual
resource assignments in the return byte stream are ignored. If the 
device is disabled when _CRS is called, it
must remain disabled.

activate:

pnp: res cnt 4
pnp: Encode io

So it appears that there is something between 574 and 857.

modprobe is still the same.

Yes, agreed. Right now just using ACPI turns pnpbios off, it probably 
should be using pnpacpi that turns pnpbios off. And turning pnpacpi off 
should be made possible.

Additionally, I see more pnp devices with pnpbios (16) than with pnpbios 
(13). Is this normal?

Couldn't find it at the first glance from my list archive - where can I 
get it?

It is using the legacy probe instead of the pnp probe. Did you actually 
apply the pnp patch?

I'm not entirely sure what has been discussed since somebody removed 
me from the CC list...

No he doesn't use the pnp patch : only latest snapshot for the stable 
Linux kernel.

But there is still the problem with pnpacpi that is needed to fixed.
