Hello,

in order to use S2API I compiled s2-lipliandvb with attached config and

ksymoops 2.4.11 on x86_64 2.6.28-gentoo.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.28-gentoo/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

The oops shows a failure happens in 

linux/drivers/media/video/cx88/cx88-vp3054-i2c.c:vp3054_i2c_probe()

Which in the source code I have lying around looks like:

int vp3054_i2c_probe(struct cx8802_dev *dev)
{
        struct cx88_core *core = dev->core;
        struct vp3054_i2c_state *vp3054_i2c;
        int rc;

        if (core->boardnr != CX88_BOARD_DNTV_LIVE_DVB_T_PRO)
                return 0;
	[...]

But the disassembed code in your oops doesn't quite match this source.

I can tell you this about the oops:

This comparison -------------------------|
corresponds to 

	if (core->boardnr != CX88_BOARD_DNTV_LIVE_DVB_T_PRO)

as 0x2a equals 42 and

	#define CX88_BOARD_DNTV_LIVE_DVB_T_PRO     42

Since that's the case, %r12 would hold the "core" pointer.  Since "core"
is fetched from wherever %rdi points %rdi should be "dev".  Since the
oops happens when %rdi is dereferenced "dev" was equal to NULL.


So linux/drivers/media/video/cx88/cx88-dvb.c:cx8802_dvb_probe() called 
vp3054_i2c_probe() with "dev" equla to NULL.  Looking at that function:


static int cx8802_dvb_probe(struct cx8802_driver *drv)
{
        struct cx88_core *core = drv->core;
        struct cx8802_dev *dev = drv->core->dvbdev;
        int err;

        dprintk( 1, "%s\n", __func__);
        dprintk( 1, " ->being probed by Card=%d Name=%s, PCI %02x:%02x\n",
                core->boardnr,
                core->name,
                core->pci_bus,
                core->pci_slot);

        err = -ENODEV;
        if (!(core->board.mpeg & CX88_MPEG_DVB))
                goto fail_core;

        /* If vp3054 isn't enabled, a stub will just return 0 */
        err = vp3054_i2c_probe(dev);
	[...]

drv->core->dvbdev must have been NULL, even though the check against
CX88_MPEG_DVB succeeded.

Backing up and looking at
linux/drivers/media/video/cx88/cx88-mpeg.c:cx8802_register_driver()
which is what registers the cx8802_dvb_probe() and calls it for each
device, core->dvbdev is never explicitly set.

Backing up even further
linux/drivers/media/video/cx88/cx88-dvb.c:dvb_init() never sets it
either.

So it must be the case, that dvbdev must be set to NULL, in a device in
the cx8802_devlist, when the cx88-dvb module is loaded.


I note that in 
linux/drivers/media/video/cx88/cx88-mpeg.c:cx8802_probe()
the cx8802 based device is added to the cx8802_devlist before the dvbdev
is set to something non-NULL.  Then a request to load modules happens.

That's probably OK for a single cx8802 device in a machine, but I think
it's a race condition if you have more than one of these cx8802 devices
in a machine.



I hope that helps someone.  I'm not and expert on the cx88 modules and
their inter-relationships.


Regards,
Andy

Sure.  I'm actually a sucker for looking at oops dumps.  They're like
simple little puzzles waiting to be solved.  Unfortunately, once I know
the "answer", I rarely follow through with the final solution.

I you run across the oops often, then the suspected race condition in
the function I mentioned needs to be fixed.  That may be as simple as
this lame patch:

Not if you don't run into the oops regularly.  You either hit this race
condition when initializing the devices, or you don't and everything is
"normal".

Thank you for the patch, I still can't tune with my HVR-4000 but at
least I don't have an oops when loading the modules.

In case anyone could be interested I attach the patch for v4l-dvb's hg.

IMO, the proper fix would be to add some locking at cx88 init. I suspect that
this breakage (and other similar ones) are tue to the absense of KBL on newer kernels.

Gregoire,

What kernel version are you using?

Better to add here:
	core->dvbdev = NULL;

Yes. Please read the README.patches file at the tree for more details.

By adding mutex locks during device init. This should be done with care to
avoid other troubles.

Ok. For sure 2.6.28 came without KBL. I'm not sure if 2.6.27 also doesn't lock
during device init.

Sorry, but I don't have any HVR-4000 here for testing. I was thinking that this
device were already working fine with S2.

Gregoire and others,
I've just commit a patch that should fix this and another reported issue when selecting parts of cx88 code as module and other parts as monolithic. 

Could you please test if the patch also fixed the OOPS and doesn't generate any regression?

Cheers,
Mauro

Edgar (Gimli),

Thanks for the report.  That's actually exactly what I would expect. 

The race I think happens should only happen after the first device is
added to the cx8802_devlist and while the cx88-dvb module is probing
devices a second device is being added to the cx8802_devlist with a
pointer not properly set yet.
(Of course, I'm not sure why Mauro's recent change didn't work for
Gregoire.)


As for Gregoire's tuning problem, I haven't looked into that, nor do I
have the hardware to play with.

Regards.
Andy

Probably because I moved also some code from cx88-mpeg into cx88-dvb. We should
rewrite the locks on the drivers to work better after the KBL unlock patches
that went on 2.6.27 and 2.6.28.


Cheers,
Mauro

Agreed. We should fix it by providing some lock to avoid having udev opening
the device before the end of the complete device initialization.

As I had to patch that file on the same point, instead of adding your
patch, I've added your logic on my patch, and added a comment pointing to your
patch at mail archives.


Cheers,
Mauro
