Things continue to be busy here at KernelLabs. This week submitted a patch upstream which results in the IR receiver support starting to work on the HVR-1150 and HVR-1120 boards. This was something that several people had been mentioning to me as an issue over the last nine months. Thanks go out to Fernando Laudares Camargos for sponsoring the work that finally got this stuff fixed. Last week we also loaned out a couple of boards to Jarod Wilson to help him do some debugging on the IR support for the cx88 and saa7134 based products. For those of you who don't know Jarod (http://wilsonet.com/),...

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 LG 42" television a couple of weeks ago. It actually runs Linux, and includes a serial port and USB port for management. I put in a request for the GPL source code last week, and the request was fulfilled today. I will be doing a diff and seeing...

I have discovered a bug today in the saa7134 driver inside the function, "saa7134_i2c_xfer" In order to communicate with certain i2c clients on the saa713x i2c bus, a quirk was implemented to prevent failures during i2c read transactions. The quirk forces an i2c write/read to a bogus address that is unlikely to be used by any actual i2c client. However, this quirk is not functioning properly. The reason for the malfunction is that the i2c address chosen to use as the quirk address was 0xfd. The address 0xfd is indeed an i2c address unlikely to be used by any real i2c client, however,...
