conexant hcf or hsf drivers on kernel 3.1.4

mathboy314 · #1 21st December 2011, 02:03 PM

Hello,

It seems that with FC16, the linuxant hsf and hcf chipset drivers (for a 56k modem) have broken. Dev at Linuxant says it is common but have not offered any solution other than to downgrade my kernel.

Here is the error that hcfpciconfig:

This is pretty much my last ditch effort to ask for a fix for this driver - anyone? anyone at all?

Try removing the line

Code:

#include <linux/spinlock.h>

From oscompat.h and osservices.c

I don't really know, but maybe "yum install kcbench-data" if it's not already installed.

Code:

Leigh,

I only found the include in the oscompat.h file and removing it threw a bunch of other pointer exception errors like:

/usr/lib/hcfpcimodem/modules/GPL/oscompat.h:216:28: error: dereferencing pointer to incomplete type

Paolo,

That package didn't help the build either.

I did find that "SPIN_LOCK_UNLOCKED" has been replaced by "DEFINE_SPINLOCK" but I don't think I can get the syntax right in oscompat.h here is what is says now:

static spinlock_t tqueue_lock __attribute__((unused)) = SPIN_LOCK_UNLOCKED;

and here is what I'am trying to get to work:

static DEFINE_SPINLOCK(tqueue_lock __attribute__((unused)));

...and am getting this syntax error:

In file included from /usr/lib/hcfpcimodem/modules/osservices.c:20:0:
/usr/lib/hcfpcimodem/modules/GPL/oscompat.h:201:2: error: expected identifier or '(' before 'static'

I think I'm going in way over my head fussing with code like this

In case anyone is interested in this fix, I finally got it working, with much thanks to "picasso_1.2.13".

The following fix is for the HCF Linuxant modem driver, however, I see no reason why it shouldn't work for the HSF driver as well.

Download the generic driver from http://www.linuxant.com/drivers/hcf/...1.i386.rpm.zip

Unzip and install the rpm with:

Code:

rpm -i hcfpcimodem-1.21full-1.i386.rpm

The hcfpciconfig will try to execute after the rpm installs and throw an error. At this point we need to begin to modify the driver.

modify /usr/lib/hcfpcimodem/modules/GPL/oscompat.h

around line 200, replace this block of code:

Code:

#ifdef STATIC_TQUEUE_LOCK
static spinlock_t tqueue_lock __attribute__((unused)) = SPIN_LOCK_UNLOCKED;
#else
extern spinlock_t tqueue_lock;
#endif

with:

Code:

static DEFINE_SPINLOCK(tqueue_lock);
extern spinlock_t tqueue_lock;

modify /usr/lib/hcfpcimodem/modules/osservices.c

around line 51, delete this line:

Code:

#include <linux/smp_lock.h>

around line 287, replace this line:

Code:

static spinlock_t atomic_lock __attribute__((unused)) = SPIN_LOCK_UNLOCKED;

with:

Code:

static DEFINE_SPINLOCK(atomic_lock);

around line 64, after the "#endif" insert these two lines:

Code:

#include <linux/mutex.h>
DEFINE_MUTEX(vmmonMutex);

throughout the rest of this file replace all occurrences of:

Code:

lock_kernel();

with:

Code:

mutex_lock(&vmmonMutex);

and all occurrences of:

Code:

unlock_kernel();

with:

Code:

mutex_unlock(&vmmonMutex);

modify /usr/lib/hcfpcimodem/modules/osnvm.c

around line 408, replace this line:

Code:

static DECLARE_MUTEX(nvmelem_writelist_sem);

with:

Code:

static DEFINE_SEMAPHORE(nvmelem_writelist_sem);

modify /usr/lib/hcfpcimodem/modules/osdiag.c

around line 33, replace this line:

Code:

static spinlock_t diag_lock = SPIN_LOCK_UNLOCKED;

with:

Code:

static DEFINE_SPINLOCK(diag_lock);

around line 602, delete this line:

Code:

.ioctl    = diag_ioctl,

modify /usr/lib/hcfpcimodem/modules/GPL/serial_cnxt.c

around line 1066, replace this line:

Code:

static DECLARE_MUTEX(cnxt_port_sem);

with:

Code:

static DEFINE_SEMAPHORE(cnxt_port_sem);

At this point you should be able to execute hcfpciconfig as normal. At some point I'll try to compile a proper .patch and include if statements for kernel versions, but for now this should work with any 3.x kernel.
