I'm trying to use puc(4) under RELENG_6 to attach the two serial ports on
a PCI card I have, but it's not working. It also fails under 6.0-RELEASE,
I don't have the ability to test earlier versions.
The card is developed, but as far as I can see, no attempt is made to
attach the sio(4) devices below it.
puc0: <Dolphin Peripherals 4036> port 0x18c0-0x18df irq 25 at device 9.0 on pci0
puc0: Reserved 0x20 bytes for rid 0x10 type 4 at 0x18c0
port rid 16 bst 0, start 18c0, end 18df
puc0: i 0, type sio, ressz 8, type 1
puc: Using sio2
puc: type 1, bar 10, offset 0
puc0: i 1, type sio, ressz 8, type 1
puc: Using sio3
puc: type 1, bar 10, offset 8
Adding some printfs to the code, it turns out that device_probe_and_attach
around line 375 of sys/dev/puc/puc.c is returning 6.
I have also added printfs to the probe and attach code of both the pci and
puc attachments of sio(4), and have determined that none of them get
How can I further diagnose why this card is not getting recognised?
