Hi,
I'm sorry, this is going to be a long email.
I manage several OpenBSD servers most of them 3.4, a couple 3.9 and one 3.7.
This particular question is about an OpenBSD 3.4-stable server that has been
running for years without needing a single reboot.
It runs postfix+amavis+clamav, mysql and apache and some other custom made
services to integrate a Webhosting Control Panel which controls all servers.
This 3.4-stable server has been working flawlessly with a generic kernel
since it was first installed and i always thank the OpenBSD team very much
for such stability.
The thing now is that this machine is on a common computer case, and i need
to put it in a rackable case to save space on the Datacenter. But the actual
motherboard won't fit in a rackable case.
So we had to go with a new motherboard and what i got is an Intel D915GAV,
which seems to be well supported on 3.9 , i've been testing this new
hardware with a 3.9 and had no problems, but i had some issues when trying
it with
3.4.
Particularly the problem is recognizing the ethernet, which is an Intel PRO
10/100.
This ethernet card is recognized by 3.4 on other motherboards, so i know the
driver must be in the kernel source. Besides that, i think that there should
be an easy way and process to add new hardware features to old OpenBSD
versions. I consider that needing to upgrade just to add a NIC is just
too 'bill gatish' , like having to reinstall a Windows 2003 server just when
needing to change the serial number.
I know that if i upgrade to 3.9, or make a 3.9 fresh install that would
solve the issue.
But i would really hate doing that just because of this hardware change, as
i said before, this 3.4 has been running perfectly, never had a single crash
or problem, so i would really like to find a way to recognize this ethernet
on
this 3.4,and other important devices i might need.
When i switched the disks to this new machine with the new mother, i
encountered some errors while booting, several devices where not recognized,
most of them USB devices which i don't need so i don't care about those,
but i care about the ethernet device, and in doubt with others.
I am not a programmer, so this might be dangerous to me to do, but i've seen
this:
According to the dmesg with the new hardware , i've seen this line (i will
paste full dmesg at bottom):
pci6 at ppb5 bus 6
vendor "Intel", unknown product 0x1064 (class network subclass ethernet, rev
0x01) at pci6 dev 8 function 0 not configured
So i figure out that this ethernet device is using 0x1064.
Then i grep for 0x1064 into src/sys/dev/pci/ from a -current source:
corsair:/u/system/cvs-sync/src/sys/dev/pci{58}# grep 0x1064 *
pcidevs,v:product INTEL 82801FB_LAN_2 0x1064 82801FB LAN
pcidevs,v:product LINKSYS EG1064 0x1064 EG1064
pcidevs,v:product INTEL 82801FB_LAN 0x1064 82801FB LAN
pcidevs,v:product INTEL PRO_100_VE_7 0x1064 PRO/100 VE (82562EZ)
pcidevs,v:product LINKSYS EG1064 0x1064 EG1064
pcidevs,v:vendor ALCATEL 0x1064 Alcatel CIT
pcidevs,v:product LINKSYS EG1064 0x1064 EG1064
pcidevs.h,v:#define PCI_PRODUCT_INTEL_82801FB_LAN_2 0x1064 /*
82801FB LAN */
pcidevs.h,v:#define PCI_PRODUCT_LINKSYS_EG1064 0x1064 /*
EG1064 */
pcidevs.h,v:#define PCI_PRODUCT_INTEL_82801FB_LAN 0x1064 /*
82801FB LAN */
pcidevs.h,v:#define PCI_PRODUCT_INTEL_PRO_100_VE_7 0x1064 /*

pcidevs.h,v:#define PCI_VENDOR_ALCATEL 0x1064 /* Alcatel

pcidevs.h,v:#define PCI_PRODUCT_LINKSYS_EG1064 0x1064 /*
EG1064 */
corsair:/u/system/cvs-sync/src/sys/dev/pci{59}#
The ethernet must be INTEL PRO_100_VE_7 for the OpenBSD kernel then.
So i think i should add in a 3.4 kernel src this in src/sys/dev/pci/pcidevs:
product INTEL PRO_100_VE_7 0x1064 PRO/100 VE
And add this in pcidevs.h:
#define PCI_PRODUCT_INTEL_PRO_100_VE_7 0x1064 /* PRO/100 VE
(82562EZ) */
After that i grep for 100_VE_7 in the -current kernel src , inside
src/sys/dev/pci:
corsair:/u/system/cvs-sync/src/sys/dev/pci{60}# grep 100_VE_7 *
if_fxp_pci.c,v: { PCI_VENDOR_INTEL, PCI_PRODUCT_INTEL_PRO_100_VE_7 },
if_fxp_pci.c,v: { PCI_VENDOR_INTEL, PCI_PRODUCT_INTEL_PRO_100_VE_7 },
if_fxp_pci.c,v: { PCI_VENDOR_INTEL, PCI_PRODUCT_INTEL_PRO_100_VE_7 },
pcidevs,v:product INTEL PRO_100_VE_7 0x106a PRO/100 VE
pcidevs,v:product INTEL PRO_100_VE_7 0x1065 PRO/100 VE
pcidevs,v:product INTEL PRO_100_VE_7 0x1064 PRO/100 VE (82562EZ)
pcidevs.h,v:#define PCI_PRODUCT_INTEL_PRO_100_VE_7 0x106a /*
PRO/100 VE */
pcidevs.h,v:#define PCI_PRODUCT_INTEL_PRO_100_VE_7 0x1065 /*
PRO/100 VE */
pcidevs.h,v:#define PCI_PRODUCT_INTEL_PRO_100_VE_7 0x1064 /*
PRO/100 VE (82562EZ) */
pcidevs_data.h,v: PCI_VENDOR_INTEL,
PCI_PRODUCT_INTEL_PRO_100_VE_7,
pcidevs_data.h,v: PCI_VENDOR_INTEL,
PCI_PRODUCT_INTEL_PRO_100_VE_7,
pcidevs_data.h,v: PCI_VENDOR_INTEL,
PCI_PRODUCT_INTEL_PRO_100_VE_7,
corsair:/u/system/cvs-sync/src/sys/dev/pci{61}#
so i figure out that i should add this in the 3.4 kernel src in
pcidevs_data.h
{
PCI_VENDOR_INTEL, PCI_PRODUCT_INTEL_PRO_100_VE_7,
"PRO/100 VE",
},
And should add this in if_fxp_pci.c , the _VE_7 line:
{ PCI_VENDOR_INTEL, PCI_PRODUCT_INTEL_PRO_100_VE_7 },
After that i think i'm ready to compile the kernel and try it.
If going this way, should i consider something else, maybe i am missing to
touch any other file? Is this too risky or dangerous? Some other devices
where not recognized or unknown, or not configured, like pchb0 or SMBus.
Is this going to be an issue if i get to make the ethernet work?
Please i would like to know your thoughts and recommendations.
