[linux-dvb] Duel Hauppauge HVR-1600

[linux-dvb] Duel Hauppauge HVR-1600

[Tom Moore]

[-- Attachment #1.1: Type: text/plain, Size: 1561 bytes --]

I just bought two Hauppauge HVR-1600 cards and I'm trying to set them up in 

Mythdorra 5. I have the cx18 drivers installed but it is only initializing
one 

card. I'm getting the following message when I do a dmesg | grep cx18. Has 

anyone ran accross this problem before with duel cards of the same model and
if 

so, how do I fix it? Any help will be greatly appreciated.

 

Thanks,

Tom Moore

You're out of vmalloc address space.  Each cx18 needs 64 MB of vmalloc
space for MMIO mappings.

Do this:

$ cat /proc/meminfo | grep Vmalloc

Edit your bootloader's config file to add a 'vmalloc=xxxM' option to
your kernel commandline.  Use a value that is 128M greater than your
current VmallocTotal.

Andy

Thanks Andy for the reply.

I did what you said and now I'm getting an memory error message when booting


The message reads:
Initrd extends beyond end of memory (0x37fef23a > 0x30000000)

I tried lowering the amount but anything over 128M and I get the error
message.

Here is my config file:
# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file

Tom,

Just a note: please don't top post.  Per list convention, please just
respond in-line.

Well, that's a new one on me.

So since vmalloc addresses are used for dynamic kernel mappings for
things like loadable module code and for IO mappings, 128 MB of
addresses will never be sufficient to support two cards that want 64 MB
of addresses each, along with other kernel vmalloc needs.

So until this problem is resolved, you won't get the second card
running.  The good news is, the problem appears to be fixable with the
proper kernel configuration.

The driver did make some suggestions in it's original error message:

both of which you could try.  They involve building a custom kernel.

There may be other ways, but I'm no expert in Linux memory management.
I suspect someone over on the LKML is.

To help solve your problem, people will likely need to see the output of
'cat /proc/meminfo' and 'dmesg' for your system.  If I had that info, I
could try to help, I'm not sure I'd be able to help effectively.

Andy

I'd go straight for an amd64 kernel, so long as the hardware supports it.
That way, the 1GB/4GB/64GB stuff becomes irrelevant.
