Building AIC94xx driver

Building AIC94xx driver

[english]

Hello everyone, 

My name is Ray Liao. I wish to help testing out the AIC94xx driver. 
I cloned the aic94xx development tree via git and tried compiling it.
The compilation completed without any error. However, when i try to
load the driver-- i received the following error message :

aic94xx: Failed to load sequencer firmware file aic94xx-seq.fw, error -2

I looked around the source code and can't find the firmware file it speaks
of. 

Can someone tell me where i will be able to find this file?

Thanks in advance for your help,

Ray Liao

booting linux from a SAS drive attached to aic94xx

[english]

Hello everyone,

First, i would like to thank Darrick Wong for pointing me to the sequencer code
for the AIC94xx. Thanks to him, i was able to get my SAS drives to work. 

Currently, my boot partition is located on an IDE drive. The aic94xx loads
successfully because the kernel has no problem detecting the IDE drive.
However, i would like to boot linux from the SAS drive that is attached to the
adaptec controller. 

I tried building the aic94xx as a part of the kernel. During the boot process,
there is an error stating that the firmware cannot be loaded (error -2). 

I also tried including the aic94xx module and the firmware on an external
initrd image. The kernel panic right after the ramdisk fails to load. I
suspect it is because the initrd image is located on the SAS drive which is
inaccessible at the moment.

If anyone knows a simple way to enable to boot linux from a SAS drive attached
to the adaptec SAS controller, please tell me.

Thanks in advance,

Mingjui Liao
