HD-PVR Linux Support

[bcjenkins]

Just a follow up:

I was able to move to kernel 2.6.28 on Arch with the newly updated driver merge from Janne. I'll post my steps, but keep in mind I also run 3 HVR-1600s

B

1. Clone hdpvr tree
2. Pull latest changes from ~awalls/v4l-dvb @linuxtv.org
3. Applied patch for ATSC tuner on HVR-1600 from mailing list
4. built modules
5. Delete /lib/modules/2.6.28-ARCH/kernel/drivers/media
6. make install
7. reboot

Was this patch integrated into the hdpvr driver? How does one configure usage in SageTV?

I don't think it has been. Once you have applied the patch and rebuilt the driver you simply need to configure the source and select Infrared Blaster when you have a choice for your tuning devices then select the i2c device of the hdpvr driver when it asks for the port.

Janne has two trees for the driver.

http://hg.jannau.net/hdpvr/
http://hg.jannau.net/hdpvr-merge/

The driver is in the first tree.

I am not sure that this is the right thread for this issue, as I am running PVR-500s, not HD-PVR, but it is all I can find on the compat_ioctl32 issue.

So I upgraded/migrated/comsolidated from a 32-bit and 64-bit systems to just the 64-bit system (both OpenSuse 11.1, 2.6.27.21), with PVR-500, and the mentioned compat_ioctr32 problem has appearently reared up. Oddly, it only effects the second tuner, the first one seems to work fine on a sustained basis, but the other one results in "No Signal", along with the mentioned kernel message and sagetv_0.txt messages.

So I went to apply the patch listed but the file names are different (I have a compat_ioctl32.c, not the needed v4l2-compat-ioctl32.c) so the patch chunks do not seem to apply. I am not that comfortable with my skillz to start changing things around, so any help would be appreciated.

Thanks!

I would do the following (please back up all files you want to keep)

1. Make sure you can compile drivers with the kernel headers installed
2. Install Mercurial
3. Clone the v4l repository
4. Run make in the new directory
5. rm all kernel modules in media and down
6. run make install
7. reboot computer

High level, I can provide more detail if needed.

As usual, you are awesome

Steps accomplished (for posterity):

1. Make sure you can compile drivers with the kernel headers installed:
   Verify kernel-headers are installed (I keep the src tree installed as well)
2. Install Mercurial
   `apt-get`, or in my case, `zypper install mercurial`
3. Clone the v4l repository
   `hg clone http://linuxtv.org/hg/v4l-dvb/`
4. Run make in the new directory
   `cd v4l-dvb;make`
5. run make install
   `make install`
6. reboot computer
   `reboot`

I also took the opportunity to upgrade to Java 1.6.0u14.

Seems to be running fine over the last day or so, clean logs. Only notable (running logs in verbose) entry:
WARNING - MissingResource: "Linux_DVB_Capture_Manager"

Thanks again B!

You left out an important step (especially for 64-bit users)

rm -Rf /lib/modules/`uname -r`/kernel/drivers/media/

prior to install. There was a change in module name for the v4l 32-bit compat layer and if the old version is not removed; it will cause issues. You could use a less brutish method as well, but I think the above is the best and most absolute one.

I just migrated sage from windows to linux (ubuntu 9.04 64bit) and got the hd-pvr setup without a hitch. I plan on adding a second hd-pvr and was wondering if anybody has done this in linux and if their are any potential problems?

[harrijay]

I have had 2 running for quite a while with no problems. Just be aware you might want to setup Udev rules to keep them in the same order if you have other types of tuners

[Taddeusz]

How well does the HD-PVR run on linux? Does it have the same issues of not responding like in Windows if you have AC3 pass-through enabled?

[harrijay]

I have both of mine running with Stereo audio input fixed resoloution of 720p and do not have any problems. I have not really tried the setting of letting the resoloution change depending on the show so I cannot speak for that. I did have them also hooked up via SPDIF without a problem for a while but when i tried to change my receivers to PCM I was getting wierd issues where I would have video but no audio. my thought was that it had something to do with the receiver sending a different audio stream half way through the show but I could not figure out what really happened.

I had mine running for a year in windows with AC3 and no issues.
I just moved to ubuntu 9.04 64 and the hd-pvr is working fine with ac3 but it has only been a week in linux

[Taddeusz]

I'm considering switching my server to Linux but I'm not sure. It's pretty stable as it is. The only thing I lack is being able to capture surround sound through my HDPVR without stability problems. It is currently capturing PCM audio from my STB and the only issues I have with it come from the STB itself.

[bcjenkins]

Once upon a time there were firmware issues with AC3 on the HDPVR related to FiOS boxes. I have not tried it since then and frankly have little use for 5.1 as we hardly watch TV in the theater room.

Any current known problems with HD-PVR capture?
Can you playback HD-PVR interlaced content (480i/1080i)?
Is VDPAU supported?
Any commercial flagging support (if not, I guess mythcommflag could be used)?

I'm a LinHES (KnoppMyth) developer and I'm considering adding in easy support for SageTV under our Arch based distro. Before I start experimenting, I would appreciate any warning of pitfalls and such. Also, is there a demo license for the Linux version?

Well, I think I have answered all my questions. Looks like Sage is backend only on Linux. And I see some are using commskip under Wine for commerical flagging. Sorry for the noise.

[loonsailor]

According to the myth wiki http://www.mythtv.org/wiki/Hauppauge_HD-PVR, HDPVR driver is included in the linux kernel by default as of 2.6.30. My ubuntu is telling me that it's 2.6.28. Any idea how one picks up a newer version? Is it in a development tree? What are the steps to get it?

[stuckless]

I actually just copied and pasted the commands directly out of the wiki that you posted, to build the driver in my Ubuntu 9.04 server.

[_Demo_]

Here are some instructions if someone wants to use the ir blaster with latest linux kernel:

in hdpvr-core.c function hdpvr_probe there is :

#ifdef CONFIG_I2C
/* until i2c is working properly */
retval = 0; /* hdpvr_register_i2c_adapter(dev); */
if (retval < 0) {
v4l2_err(&dev->v4l2_dev, "registering i2c adapter failed\n");
goto error;
}
#endif /* CONFIG_I2C */

that should be changed to put back

retval = hdpvr_register_i2c_adapter(dev);

and also in hdpvr-i2c.c function hdpvr_i2c_write

it says

if (ret == 2)
ret = 0;
else if (ret >= 0)
ret = -EIO;

this should be changed to :

if (ret == 2 && buf[1]==(len-1))
ret = 0;
else if (ret >= 0)
ret = -EIO;

for better reliability.

I have followed the thread between you and loonsailor, and think this is the last thing I haven't tried to get the blaster working in linux.

I am not knowledgeable about where this code change is or how to do it. Can you (and I know its annoying when us less technical folk attempt this), lay out the steps to make this change - where is the file, how do I edit it, and compile it in order.

I have been forced to linux because the HD PVR simply does not like the windows box. Even before I get the ir blaster working, it is the first time the darn HD PVR box didn't shut down after changing channels...

any help is welcome.
