| Post subject: | Kernel Recompile |
Bare with me as i'm adequate with linux but by no means an expert. And i've never really compiled a kernel before. Ok, so i have an SIS 305 or something video card with tv-out. For some reason it doesn't work in linux but with Thomas Winischhofer's (http://www.winischhofer.net/linuxsisvga.shtml) sis driver it works great. But one thing about the tv-out port is it doesn't display the text when booting up. It displays two white triangles. From Thomas i gather that this is due to how the kernel handles the frame buffer. He's written a sis frambuffer but it has to be compiled into the kernel. So i undertook this the other day and compiled the kernel with his frame buffer in it. It worked up until the kernel was missing stuff in it's boot up. I looked up the error message on google (escapes me now) and it had something to do with modules not being installed. So i was wondering, obviously i didn't select things that i needed to, is there a program to run to gather the information from your current kernel, select what you need and just change what you have to for the sis frambuffer? Or a listing in detail of what i have to select for the KnoppMyth kernel. Or out of curiousity the sis frambuffer is installed by overwritting certain .c and .h files for sis. Is it possible that R5 have this already? |

to get the same config as knoppmyth you need to change to the kernel source dir usually /usr/src/linux/ and cp /boot/config-kernel-version .config the file won't be config-kernel-version it will actually have numbers and letters in it, but keeping it generic it will work for any distro not just knoppmyth. then you should run make oldconfig then your kernel will be configured with the same options that the binary kernel was compiled with. |

that's why I said cd into your kernel source. you'll notice a space in the command I have that will make it copy to a file called .config in the current directory. |

I recompiled the kernel and rebooted, the frame buffer worked, but all i got was a black screen when trying to watch live tv, and the lircd doest work, lircd runs but if i try to run irw or mythtv it shuts back down. I don't know what i have to do to get these things to work with the new kernel. I ran make oldconfig, and it went fine. anyways any help? btw i'm using a pvr 250. |
