Adaptec SlimSCSI 1480A

Hi,

I am trying the hotplug facilities. If I understand it correctly, the kernel call a user space tool which is then in charge of loading drivers for the just plugged device. Then kernel supporting the hotplug API are used (drivers providing standby/resume).
Cardbus card are usable without pcmcia stuff.

I've a kernel 2.4.11 with hotplug support enabled.
I own a laptop Toshiba 2520cds with a pcmcia/cardbus slot and two cardbus cards : a 3com Megahertz 10/100 lan and an adaptec SlimSCCI 1480A.

The first one is well managed by hotplug. The correct driver is loaded and
the network interface is configured. But the second one is not detected.

Nothing is written in /var/log/message and on the console when I insert my
scsi card.
Is there some debugging tools ?

With pcmcia, the correct driver was apa1480 but if I have correctly understood the driver with hotplug is aic7xxx.

My card works with pcmcia but only when inserted before booting.

After further investigation, it appears that :

. My card is sometimes detected.
it looks like a mechanical problem. After 20 insertion, the card is
finally datected and I see:
cs: cb_alloc(bus 20): vendor 0x9004, device 0x6075
PCI: Enabling device 14:00.0 (0000 -> 0003)

. The driver is not loaded automatically.
If I understand correctly it is because the aic7xxx is not define in the /lib/modules/2.4.11/modules.pcimaps file.

Why AIC7xxx is not define in modules.pcimaps ?

Because the author of that driver has not included the proper chunk of code in the driver. Could you add the line:

MODULE_DEVICE_TABLE(pci, ahc_linux_pci_id_table);

at the end of aic7xxx_linux_pci.c, rebuild everything, reinstall the modules, and then see if the autoloading stuff works?

thanks,

I've tried your modifications with the 2.4.12 upgrade.
I've applied the attached patch.
The pcimaps file still doesn't include any reference to the aic7xxx modules even if the module is there.
It works if I modprobe it.

What does:
nm aic7xxx.o | grep module_pci
show when you do that on the module you have modified?

thanks,
