BCRaid progress

Greetings all,

I was able to make just a tiny bit of progress in this regard. I have
a clean install and was able to get the driver to load. This is what I
did.

Starting with the RaidCore Linux SDK (
http://www.raidcore.com/Downloads/V2.1/LIN-DRV-SDK_RC-210-2006044_3.tar
).

Go to the bcraid directory -- this is the only part I have compiled so
far. The bccfg remains unusable.

1. Copy the Makefile_2.6 to Makefile

[pauly@flux bcraid]$ pwd
/home/pauly/src/LIN-DRV-SDK/bcraid
[pauly@flux bcraid]$ cp -p Makefile_2.6 Makefile

2. Comment out the line 329 in bc_init.c (the line with
"eh_strategy_handler").

eh_abort_handler: bc_eh_abort_cmd, /* Abort
Command */
// eh_strategy_handler: NULL, /* Strategy
Error Handler */
eh_device_reset_handler: bc_eh_dev_reset, /* Device Reset
Handle */

3. Comment out the lines in bc_mem_ops.c that define the page_to_pfn
and the pfn_to_page macros, starting at line 410:

//#ifndef page_to_pfn
//#define page_to_pfn(page) ((unsigned long)((page) - mem_map))
//#endif

//#ifndef pfn_to_page
//#define pfn_to_page(pfn) (mem_map + (pfn))
//#endif

4. Type Make, and viola:

[pauly@flux bcraid]$ make
make -C /lib/modules/2.6.17-1.2187_FC5/build
SUBDIRS=/home/pauly/src/LIN-DRV-SDK/bcraid modules

As a final check:

At this point I am able to get it to install and it looks like it's in
good shape, but when I reboot the server the kernel does not pick it up
at boot time.

Any thoughts?
