Configure MythTV kernel
Here are the settings I use for my MythTV box.
First off, the gear:
AMD Athlon 64 X2 3800+ Manchester 2.0GHz Socket 939 MSI K8NGM2-FID NForce 430 GeForce 6150 8 channel HD audio codec RealTek ALC880 (INTEL) Hauppage PVR-350
So what do we need in menuconfig? Select the following, in addition to all the defaults:
<*> Loadable module support -> Automatic kernel module loading (why is this not on already?) (FOR NVIDIA) <*> Device Drivers -> Graphics support -> Support for frame buffer devices <*> Device Drivers -> Graphics support -> VESA VGA graphics support <*> Device Drivers -> Graphics support -> VESA driver type -> vesafb (the only choice) < > Device Drivers -> Graphics support -> nVidia Framebuffer support (INCOMPATIBLE with binary driver) < > Device Drivers -> Graphics support -> nVidia Riva support (INCOMPATIBLE with binary driver) (FOR HAUPPAGE) (old) <*> Device Drivers -> Multimedia Devices -> Video For Linux [*] Device Drivers -> Multimedia Devices -> Enable Video For Linux API 1 (DEPRECATED) <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> BT848 Video For Linux <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> SAA6588 Radio Chip on BT848 cards (new, what a bunch of kernel muckups) <*> Device Drivers -> Multimedia Devices -> Video For Linux [*] Device Drivers -> Multimedia Devices -> Enable Video For Linux API 1 (DEPRECATED) < > Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Autoselect pertinent encoders/decoders and other helper chips Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Encoders/decoders -> <M> Micronas MSP34xx audio decoders <M> Wolfson Microelectronics WM8775 audio ADC with input mixer <M> Conexant CX2584x audio/video decoders <M> Philips SAA7110 video decoder <M> Philips SAA7111 video decoder <M> Philips SAA7114 video decoder <M> Philips SAA7113/4/5 video decoders <M> Philips SAA7191 video decoder <M> Conexant CX2341x MPEG encoders <M> Philips SAA7127/9 digital video encoders (FOR INTEL HD AUDIO (ALC880) and ALSA - 'use modules so alsa-config works') <M> Device Drivers -> Sound -> Sound Card Support < > Device Drivers -> Open Sound System -> Open Sound System (DEPRECATED) <M> Device Drivers -> Sound -> Advanced Linux Sound Architecture -> Advanced Linux Sound Architecture <M> Device Drivers -> Sound -> Advanced Linux Sound Architecture -> Sequencer support <M> Device Drivers -> Sound -> Advanced Linux Sound Architecture -> OSS Mixer API <M> Device Drivers -> Sound -> Advanced Linux Sound Architecture -> OSS PCH (digital audio) API <*> Device Drivers -> Sound -> Advanced Linux Sound Architecture -> OSS PCH (digital audio) API - include plugin system <M> Device Drivers -> Sound -> Advanced Linux Sound Architecture -> PCI Devices -> Intel HD Audio (FOR IVTV, stupid unfriendly piece of crap) <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Conexant 2388x <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Encoders and Decoders -> Wolfson WM8775 <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Encoders and Decoders -> Wolfson WM8739 <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Encoders and Decoders -> Conexant CX2341x <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Encoders and Decoders -> Conexant CX2584x <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Encoders and Decoders -> Philips SA711x <M> Device Drivers -> Multimedia Devices -> Video Capture Adapters -> Encoders and Decoders -> Philips SA712x (FOR SAMBA, and the newer CIFS) <*> File Systems -> Network File Systems -> SMB file system support <*> File Systems -> Network File Systems -> CIFS support
P.S. It can be helpful to compare the new .config file with the older working version to check to see if you missed anything:
kdiff3 ../linux-2.6.17-gentoo-r8/.config .config
P.P.S. Kernel hackers all use the 'oldconfig' option of make menuconfig - gentoo says only 'safe' if you're in the same kernel revision (e.g. 2.6.18-r4 to -r6):
cp ../linux-##older_working_kernel##/.config ./ make oldconfig (this will prompt you to decide about including the newest features...) make && make modules_install (etc.)
