Future of the Linux-Driver

[hda]

If you read back through the thread there are 2 edits to make to linux/drivers/media/video/v4l2-compat-ioctl32.c

For me this enables the driver to build but then I get the failure when I try to insert the module.

I get the failure when I try to insert the module.

Heh! I'm also trying to install TBS6891 into a Fedora14 machine (with 2.6.35 kernel so should be supported without any patch) I do have to add a #include for slab.h which is no big thing, then it all builds but now *I* get lots of module errors

Other than my 2.6.38 test machine being newer with Fedora15, I've got everything else the same (kernel-PAE-devel, kernel headers etc) ... I can't figure out why it rejects the modules ... damn!

ir_core: exports duplicate symbol ir_raw_handler_unregister (owned by rc_core)


OK, it's a duplicate symbol clash ... caused by my imon_pad, I can live without that for a while until I resolve it

[hda]

Strange. I had no problems with 2.6.35 even on 64bit.

Have you had any chance to look into the 64bit side of things for 2.6.38 yet Andy?

Me being totally selfish here as I'm gonna have to boot into my 2.6.35 kernel to watch the footy later :p

[jkpiodsoea]

Bravo, is simply magnificent idea

[AndyBurns]

Strange. I had no problems with 2.6.35 even on 64bit.

Turned out to be related to a module I'd loaded for my iMON PAD remote, worked around for now by blacklisting that.

Have you had any chance to look into the 64bit side of things for 2.6.38 yet Andy?

Err no ... today the postie delivered a PCIe riser card I've been waiting for that's allowed me to fit the TBS card into a dedicated mythTV machine tonight, so I've been sampling the delights of Freesat HD for the first time ... I have to say that NHK World HD (which is broadcasting in stealth mode until 1st May) looks better than any of the four UK HD channels

But I have plenty of spare LVM room on this machine, so I'll have a bash at 64bit later ... Fedora 15 beta 64bit ISO downloading now ...

[hda]

Brilliant. Really looking forward to getting this thing working with latest kernels =]

Will have to check out this NHK World HD channel after the football.

[AndyBurns]

Will have to check out this NHK World HD channel after the football.

It's in "stealth" mode at the moment, so not visible in EPG, but mythTV finds it ...

Satellite: Eurobird1
Channel: 53147
Transponder: 11223.67MHz Vertical
Symbol Rate: 27500
FEC: 2/3

C4HD has de-stealthed today ....

Have you had any chance to look into the 64bit side of things for 2.6.38 yet Andy?

Yes, I installed a Fedora15 Beta 64bit machine (2.6.38.2 kernel),
V4L built using the v4 patch plus the two extra tweaks for v4l2-compat-ioctl32.c.org (I'll make a V5 patch including those)

After building and installing, I rebooted, then tried modprobe cx23885 but it I had a symbol clash with my iMON PAD again (same as 32bit)

Code: Select All Code

ir_core: exports duplicate symbol ir_raw_handler_unregister (owned by rc_core)

so I removed the iMON stuff

rmmod imon
rmmod rc_imon_pad
rmmod rc_core

then modprobe cx23885 worked nicely, and scandvb picks up channels, I'm just going to install mythTV now

So I might not be able to help you much further, since it works for me

What exact messages do you get when you modprobe? anything in dmesg?

[hda]

Just tried again.

modprobe

Code: Select All Code

FATAL: Error inserting cx23885 (/lib/modules/2.6.38-ARCH/kernel/drivers/media/video/cx23885/cx23885.ko): Unknown symbol in module, or unknown parameter (see dmesg)


dmesg

Code: Select All Code

rc_core: exports duplicate symbol ir_raw_handler_unregister (owned by ir_core)
cx23885: Unknown symbol v4l2_i2c_new_subdev_cfg (err 0)


I see you have similar error but I dont have any imon or rc_core stuff loaded.

Will try again with the v5 patch when available just to make sure I am not messing up the edits.
