Re: [Iprdd-commit] Mylex card detection and irdd driver

Brian:

Thanks for the response.

The card is an IBM card:

[root@martha ~]# lspci -v -s 03:03.0
03:03.0 SCSI storage controller: Mylex Corporation AcceleRAID
600/500/400/Sapphire support Device (rev 04)
        Subsystem: IBM Dual Channel PCI-X U320 SCSI Adapter
        Flags: bus master, 66MHz, slow devsel, latency 32, IRQ 7
        BIST result: 00
        Memory at dd200000 (64-bit, non-prefetchable) [size=256K]
        Memory at df800000 (64-bit, prefetchable) [size=8M]
        Capabilities: [40] PCI-X non-bridge device
        Capabilities: [50] Message Signalled Interrupts: 64bit+ Queue=0/0
Enable-
        Capabilities: [78] Power Management version 2


Let me as a stupid question first:  All the references I see for the ipr
driver only speak of Linux on Power.  The xSeries uses a PowerRAID card. 
I realize this are two very different animals; one is a system
architecture, and the other is a marketing name for a SCSI controller,
but it's a bit confusing.

So, Before for we go to much further, I should ask;  is this card only
for the POWER architecture, or will it work in the x86 arch?

Then, if it will work in an x86 server, there is no ipr kernel module for
an 2.6 x86 kernel in the sourceforge source.  Where can I get it?

Thanks a bunch;

Eric
