We’ve had a handful of reports cropping up related to HVR2200 model#89619 cards. With Ubuntu 12.04.1 the driver would attempt to load firmware from file NXP7164-2010-03-10.1.fw length 4019072 as defined in the saa7164-fw.c driver source.

Osprey 820e patches – merge has been requested
Good news. After our ViewCast Osprey 820 drivers were released earlier this year, we held off requesting an upstream merge knowing that we’d have to give them a whitespace cleanup, and we also wanted to gather public feedback prior to any formal peer review. After 3 months, no negative feedback and continued reliability during testing,… Read More
HVR-950q Closed Captioning support
Hello all! If anyone is interested in closed captioning support for the HVR-950q, you can get it from the following tree: http://kernellabs.com/hg/~dheitmueller/v4l-dvb-950qvbi Unfortunately, the work exposed a bug in tvtime which prevented it from working, which I fixed here: http://kernellabs.com/hg/~dheitmueller/tvtime But it *is* working with zvbi-ntsc-cc out of the box. Comments welcome, as always. Next… Read More
HVR-1600 Performance changes merged
Just a heads up to those who were kind enough to try out my testing tree for the HVR-1600 ClearQAM performance improvements: the fixes were merged into the mainline on Friday. So at some point you should stop using my private tree and switch back to the mainline v4l-dvb tree at: http://linuxtv.org/hg/v4l-dvb My tree will… Read More
Call for Testers: HVR-1600 Improvements
If you are an HVR-1600 user who has noticed the ClearQAM tuning performance under Linux was worse than under Windows, this should make you happy. As a result of the work described in the previous post, there is now a tree that contains the various fixes: http://www.kernellabs.com/hg/~dheitmueller/hvr-1600-perf-2 The goal is to submit this upstream, but… Read More
Em28xx audio panic
I started working on the media controller stuff again, and was unfortunately sidetracked when I realized that any attempt to stream audio against my HVR-950 would cause the kernel to panic. Spent most of the evening chasing down the bug in the isoc handling code which would cause a page fault. Issued a PULL request… Read More
HVR-950q, em28xx GPIOs, and Dib0700 Firmware
Did some more testing of the HVR-950q under MythTV. Wrote some patches to get rid of a couple of spurious error messages. However, in the end the code currently in the v4l-dvb codebase today does work with MythTV, as long as you have the latest snapshot of 0.22, use the no_poweroff xc5000 modprobe option, and… Read More
HVR-950Q and MythTV: Now working….
After three nights of debugging various issues, I now have the analog side of the HVR-950Q working properly with MythTV. Special thanks go out to Janne Grunau for promptly merging my patch providing UYVY support to MythTV: http://svn.mythtv.org/trac/changeset/22343/trunk I will be setting up a tree this weekend with the 950q fixes. In the end, we… Read More
TDA18271 bugfixes
There are some TDA18271 bug-fix patches awaiting merge that improve tuning performance significantly. I’m hoping these get merged and sent up to Linus very soon, so that they can be backported into the -stable kernel series.
Patch backlog
Finally getting caught up on a bunch of patches from various users I have been dealing with via email. Issued a PULL request tonight, which should make those people happy (as well as everyone else using the effected products) http://kernellabs.com/hg/~dheitmueller/misc-fixes3 On a personal note (but perhaps of interest to this crowd), I bought a new… Read More
