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.

SAA7164 – Releasing into LinuxTV.org
We’ve reached the end of a major milestone. SAA7164 is ready to be merged into the master LinuxTV repositories at linuxtv.org. For cleanup and ease of merging I’ve extracted all of the patches from saa7164-stable and created saa7164-merge. I’ve asked Mauro to review and merge at his earliest convenience. I want to take this opportunity… Read More
SAA7164 – HVR2250 – Not tuning above channel 91?
We’re looking to reports from two people that say they’re having issues tuning to channels 91 and above with the HVR2250 Model 88061 / C3F2. Update: Patches for the issue are available in the saa7164-dev tree.
SAA7164 New Patches
I’ve posted a new set of patches to the saa7164-dev tree. The significant change relates to how the driver deals with command queueing in an effort to resolve commands that have appeared to ‘timeout’, often seen as I2C message failures. One of the positive side effects is that these patches also lower the overall system… Read More
Using HVR-2200/MythTV in Australia?
If you’re running MythTV with an HVR2200 in Australia then I need to hear from you! I spent six hours over the weekend logged in remotely to an Australian users system trying to track down a problem that was seemingly preventing the driver from responding correctly after being loaded. Requests into the firmware were being… Read More
Ready, or not?
Yesterday I spent most of the day testing the saa7164-stable tree on Ubuntu 8.10 (Intrepid) 64bit Desktop. In previous tests here, here, here and here everything largely went well on both ATSC/QAM and DVB-T, on our both 32 and 64bit platforms. The change history in the saa7164-stable repository shows that the tree hasn’t needed (or… Read More
SAA7164 debugging / chat
Today (July 18th) I’m going to spend the entire day trying to force a hang on the -stable driver with an HVR-2250. This will be a combination of tests using MythTV with LiveTV and background recording. I’ll also be on IRC for most of the day (on and off) so if you have HVR-2250 or… Read More
SAA7164 Episode #2
I’m beginning to wonder what would happen if the deferred worker thread, responsible for dequeueing the DMA buffers after interrupt, and updating the device registers, got so far behind that the DMA buffers we’re finally trying to dequeue have wrapped and are currently in use again. Hmm, that would cause awkward things to happen and… Read More

A handful of people have asked about current and future support for the SAA7164 features. Digital TV, Remote control, Analog, VBI, FM Radio, Raw Video and Encoded video for NTSC, PAL and SECAM. Firstly, thank you for writing. Second, I thought it would be useful to outline the current status and future roadmap for the… Read More
