Hi, Google tries to convince me that the Philips / NXP / Trident / SigmaDesigns SAA7231 chip is not (and will probably not be) supported on Linux (mostly because of bad will from the hardware companies).
Could you please confirm that this chip is not (and will probably not be) supported [1] ? Thanks for your time [1] as opposed to other SAA71x chips, as seen in 3.2 kernel headers and on http://linuxtv.org/wiki/index.php/DVB-T_PCI_Cards You'll find details below (chip details / history, partial output of lspci -v / vv, hardware, uname -a) 1. Chip history: - announced by NXP (2008-03): http://www.nxp.com/news/press-releases/2008/03/nxp-launches-world-s-smallest-single-chip-triple-mode-pctv-solution.html - some guy at a German company began devlopments but this seems discontinued http://osdir.com/ml/video4linux-list/2010-07/msg00016.html and the src code url is dead / 404: http://www.jusst.de/hg/saa7231/ - Trident was the next owner. See TV > PC TV > SAAA link from the CX2450X page http://www.tridentmicro.com/producttree/stb/satellite-stb/cx2450x/ but they refused to give any help to linux develpers -- then finally filed for bankrupcy http://forums.opensuse.org/english/get-technical-help-here/hardware/450034-saa7231-module-2.html https://www.linux.com/community/forums/multimedia/installing-and-using-a-saa7231-tv-card/limit/20/offset/0 - the current owner seems to be Sigma Design for the SAA71x (and perhaps the SAA72) chips http://www.sigmadesigns.com/uploads/library/press_releases/120402.pdf 2.
