Hi I'm attempting to get an HVR2205 up and going. CORE saa7164[1]: subsystem: 0070:f120, board: Hauppauge WinTV-HVR2205 [card=13,autodetected] Distribution is CentOS7 so I've pulled the v4l from media_build.git Had to change a couple of things.. and another macro issue regarding clamp() .. Seems the kzalloc(4 * 1048576, GFP_KERNEL) in saa7164-fw.c was failing.. kept getting: kernel: modprobe: page allocation failure: order:10, mode:0x10c0d0 Have plenty of RAM free so surprised about that one.. tried some of the tricks re increasing the vm.min_free_kbytes etc.. Any way I modified the routine to only allocate a single chunk buffer based on dstsize and tweaked the chunk handling code.. seemed to fix that one.. fw downloaded and seemed to boot ok.. Next I'm running into a problem with the saa7164_dvb_register() stage... saa7164[1]: Hauppauge eeprom: model=151609 saa7164_dvb_register() Frontend/I2C initialization failed saa7164_initdev() Failed to register dvb adapters on porta I added some extra debug and identified that client_demod->dev.driver is null.. However I'm now stuck as to what to tackle next.. I can provide more info, just didn't want to spam the list for my first email.. Regards Richard Tresidder
