Hi guys:
My situation is:
(1) We are porting our HBA driver (Promise FastTrak TX4310 SoftRaid5) from
Linux to FreeBSD(6.0). Our HBA driver can work normally under Linux.
(2) At this time, I just wrote a sample driver code (see sr5.c in the
attached file) to check the driver's probe function in FreeBSD.
(3) After I successfully compiled the codes, I run "make load" (see Makefile
and load.info in the attached file) for testing.
(4) Our probe function was called indeed, but no matching pci device was
found! (Yes, I have plugged our HBA card in the system).
(5) Our HBA card information can be found by running pciconf (see
pciconf.info in the attached file).
The only two storage devices in the pciconf output are:
[EMAIL PROTECTED]:7:1: class=0x01018a card=0x74411022 chip=0x74411022
rev=0x04 hdr=0x00
vendor = 'Advanced Micro Devices (AMD)'
device = 'AMD-768 EIDE Controller'
class = mass storage
subclass = ATA
[EMAIL PROTECTED]:4:0: class=0x010400 card=0x3515105a chip=0x3515105a
rev=0x02 hdr=0x00
vendor = 'Promise Technology Inc'
class = mass storage
subclass = RAID
The first looks like the ATA controller on the motherboard. The second
is your Promise ATA RAID card. Both devices are already attached by
FreeBSD's ATA framework. You will need to patch FreeBSD's ATA framework
to not detect your card. The attached patch should do the trick (it
removes the corresponding PCI ID for your card). I tested the patch to
the point that it compiles, but I can't guarantee this will prevent the
attach or even result in a bootable kernel, so test carefully.
To apply the patch, do the following with root privileges:
cd /usr/src # Replace /usr/src with the base of your src tree.
patch </path/to/ata_no_PDC40719.diff
If you have ata compiled into your kernel, rebuild your kernel. If
you're loading the ATA modules, you can get away with just rebuilding
the ata modules:
cd /usr/src/sys/modules/ata
make clean && make depend && make && make install
