Upgrading to Ubuntu 10.10 caused my HDPVR ir blaster to stop working, again\u2026<\/p>\n
I had to re-figure out how I got it working int he first place, so I figured I\u2019d write it down this time.<\/p>\n
Ubuntu 10.10 comes with hdpvr drivers compiled and included in \/lib\/modules\/2.6.35-24-generic\/kernel\/drivers\/media\/video\/hdpvr\/hdpvr.ko
\nBUT these drivers DO NOT support using the IR blaster function.<\/p>\n
So you have to compile them yourself.<\/p>\n
The lirc_zilog driver which is needed is included with 10.10 ubuntu ( it is in the staging area: \/lib\/modules\/2.6.35-24-generic\/kernel\/drivers\/staging\/lirc\/lirc_zilog.ko)<\/p>\n
But in previous versions I had to compile that separately, but this time it worked using the distributed version.<\/p>\n
To get the hdpvr drivers recompiled, I used the source code I had working before. I think I got it from the links on this page: http:\/\/www.mythtv.org\/wiki\/HD-PVR<\/a> Usually the drill when you get a new kernel is to go to the directory for the hdpvr and But this time it wouldn\u2019t compile.<\/p>\n I had to change some function calls that had been renamed in the new kernel:<\/p>\n Change: And the the video_is_unregistered function call to be changed to ( ! video_is_registered )<\/p>\n All working again \u2014 and now I have mythtv 0.24 \ud83d\ude42<\/p>\n I have the apps in \/usr2\/apps\/hdpvr ( got the <\/p>\n","protected":false},"excerpt":{"rendered":" Upgrading to Ubuntu 10.10 caused my HDPVR ir blaster to stop working, again\u2026 I had to re-figure out how I got it working int he first place, so I figured I\u2019d write it down this time.
