<pre>I've been trying to test the IR blaster functionality on my HD-PVR with this patch,<br>unfortunately I'm running into some issues. First I tried option 1, the prebuilt<br>Fedora kernel package, and using that lirc_zilog recognizes the hd-pvr's ir <br>
<br>chip perfectly and I've been able to successfully use it to change channels on my<br>cable box. However, using that version causes the hd-pvr to lock up randomly 5-10<br>minutes into a recording, and attempting to modprobe -r either the hdpvr or<br>
<br>lirc_zilog modules hangs and eventually leads to a kernel oops after a minute or<br>so.<br><br>I decided to try to follow your 2nd suggestion and pull your 2.6.31 git tree by cloning<br>Linus' and then adding you as a remote to see if it was any more stable. I also applied<br>
<br>the <i><a href="http://wilsonet.com/jarod/junk/hdpvr-ir/hdpvr-ir-enable.patch" target="_blank">http://wilsonet.com/jarod/junk/hdpvr-ir/hdpvr-ir-enable.patch</a></i> as you said to.<br>The kernel compiles and boots fine and the hdpvr records without any of the instability<br>
<br>I observed with your precompiled Fedora kernel, however the lirc_zilog module no longer<br>recognizes the IR chip. When I run modprobe lirc_zilog debug=1 I get:<br><br>lirc_dev: IR Remote Control driver registered, major 248 <br>
<br>lirc_zilog: Zilog/Hauppauge IR driver initializing<br>lirc_zilog: initialization complete<br><br>but no mention of it probing for the device. I've looked through lirc_zilog.c a bit and<br>it seems that in 2.6.31 the ir_probe function is never getting run, whereas it is in 2.6.30,<br>
<br>but I haven't been able to figure out why. I've checked to make sure that the hdpvr i2c adapter<br>is still being created using i2cdetect and it shows:<br><br>i2c-0 i2c Hauppauge HD PVR I2C I2C adapter<br>
<br><br>which is the same as for the 2.6.30 kernel. Any idea what I'm doing wrong? Thanks for all<br>the work you've already put in to getting the driver working.<br><br>Victor<br><br><br>On Sep 12, 2009, at 4:06 PM, greg pryzby wrote:<br>

<br></i>><i><br></i>><i> Or has this stuff been moved upstream now?<br></i><br>For some value of, yes. All the hdpvr driver bits are in Janne's hdpvr <br>tree, but I don't believe they've been pulled over to the main v4l-dvb <br>
<br>tree, and definitely didn't go into kernel 2.6.31. The lirc bits are <br>in my lirc git tree. I suppose I should forward a copy of things over <br>to Mark Weaver, the originator of lirc_pvr150, but at this point, its <br>
<br>quite different from lirc_zilog, I believe (2.6.31 i2c changes, hdpvr <br>support additions, other cleanups)...<br><br><br>><i> THANKS for all the work. Finally have some free time to get this <br></i>><i> ironed out.<br>
