RAIDCore BC4852 on Slackware 10.2 compile error

Borderline · 11-06-2005, 01:41 AM

Hi, I have a iWill DK8X with a RAIDCore BC4852 running the stock Slackware 10.2 kernel sata.o 2.4.31.

My problem is that slackware reconizes my RAID card as a:

"04:02.0 RAID bus controller: Broadcom RAIDCore RC4000"

and uses a driver that will only allow me to see 4 of the 8 SATA drives that are connected.

So, in order to get all 8 drives working, I have to install the bcraid driver from Broadcom's website. From what I gather, on 2.4 kernels this driver can not be compiled externally, it must be patched into the kernel and compiled.

Well, after I patch the Makefile and the Config.in I run
. # cd /usr/src/linux
. # cp .config ~/
. # rm -rf /lib/modules/2.4.29
. # make mrproper
. # cp ~/.config ./
. # make menuconfig

I configure the kernel to use then new driver then make dependencies:
. # make dep

And finally I do a:
. # make clean bzImage modules modules_install

and I get the following compile error:

So I opened /usr/src/linux-2.4.31/drivers/scsi/bcraid/bc_mem_ops.c to have a look....

Code:

bc_kthread(void *bc_threadp)
{

        int             cpu, status, i;
        bc_thread_t     *tp;
        bc_mem_op_t     *mop;
        bc_softstate_t  *state;
        unsigned long   irql;
        cpumask_t       cpumask;

        state = &bc_state;

        tp = (bc_thread_t*)bc_threadp;

        cpu = tp - bc_thread;

This doesnt really mean anything to me but maybe it does to one of you?

Any help getting this binary to compile will be greatly appriciated.

I got some help from a generous admin at #linux-help on efnet last night.

We made some progress by opening /usr/src/linux-2.4.31/drivers/scsi/bcraid/bc_mem_ops.c and going to line 170

Code:

/* 2.4.22 added a typedef for cpumask_t, need to define it for earlier versions. */
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,4,22)
typedef unsigned long cpumask_t;
#endif

and commenting out the If statement to look like this

Code:

/* 2.4.22 added a typedef for cpumask_t, need to define it for earlier versions. */
/*#if LINUX_VERSION_CODE < KERNEL_VERSION(2,4,22)*/
typedef unsigned long cpumask_t;
/*#endif*/

This generated a new error that was fixed by symbolically linking bcblob.i386 to bcblob.unknown

Quote:

cd /usr/src/linux-2.4.31/drivers/scsi/bcraid
ln -s bcblob.i386 bcblob.unknown

However, yet another error occured.

Quote:

drivers/scsi/scsidrv.o(.text+0x10320): In function `kernel_fpu_begin':
: multiple definition of `kernel_fpu_begin'
arch/i386/kernel/kernel.o(.text+0x7210): first defined here
make: *** [vmlinux] Error 1

And this is were I sit.

Heres an update:

I've managed to get it working on the 2.6 kernel but my ethernet card doesn't support 802.3ad on 2.6. So Ive decided to go with a different card.

I noticed the Promise SATAII150 SX8 driver come integrated in the 2.4 kernel and Promise claims it "Delivers more than 500MB/sec sustained throughput in sequential access" So I've ordered one and I'm going to try it.

The SX8 doesn't have driver RAID but I intend to use linux RAID instead anyway. Which is another reason for the switch, the BC4852 ONLY functions as a RAID controller. Devices are only visible when defined on its RAID array software.
