RE: eata.c module and PCI setup problem (RAID SCSI card)
Hello all,
Thank you for your feedback and sorry for being late. I was the whole
week in a Juniper training in Holland and had not been able to test this
new driver. I just done it today.
Here is the syslog output I've got when doing 'insmod eata.o' or 'insmod
eata.o io_port=0x1410' :
Jun 15 14:43:50 brocoli kernel: PCI: Enabling device 00:0f.0 (0014 ->
0015)
Jun 15 14:43:50 brocoli kernel: EATA: detect, seq. 0, bus 0, devfn 0x78,
addr 0x1400.
Jun 15 14:43:50 brocoli kernel: EATA0: warning, weird ISA board not

Jun 15 14:43:50 brocoli kernel: EATA0: warning, DMA protocol support not

Jun 15 14:43:50 brocoli kernel: EATA0: warning, LEVEL triggering is
suggested for IRQ 3.
Jun 15 14:43:50 brocoli kernel: EATA0: unable to allocate IRQ 3,
detaching.
The module does not load and the card hangs (the two extreme leds lid
up). For reference the lspci -vv output after that is :

As the IRQ number is not the same, I tried a dirty quick hack in the
code to set it to 25. Here is the output of 'insmod eata.o
io_port=0x1400' afterward :

And then insmod and the card are hanging... with no other possibility
than a reboot. I suppose the 4 bits in eata_info for the IRQ should be
translated to something else ... but in what ? I also suppose there are
other thing in this struct that have to be translated. I'll try to
print the whole eata_info struct if I have time tomorrow or monday.
If you have other suggestions or improvements, they are welcomed.
Have a nice week-end !
Antoine.
