Hi all, I have a question about incorporating existing I2C support in kernel.1) In order to have working peripherel on I2C bus I have to insmod: a) i2c-core.o b) i2c-dev.o c) i2c-proc.o d) i2c-.o e) i2c-.o
Am I right? Did I miss something?2) More important question: I enabled I2C support in make menuconfig, for I2C code to be built in a kernel, not as a modules. I check for "I2C device interface", but left unchecked for "I2C Algorithms" and "I2C Hardware Bus support" since I do not have yet implemented support for my board (for AMBA bus). Now I can see i2c directory under /sys/bus (under /dev I can not see anything with i2c name). I'd like to know which one of these '.o' files got build in a kernel. I suppose i2c-core.o, i2c-dev.o and i2c-proc.o, and I have to insert then i2c-.o (which I did not checked in menuconfig) and i2c-.o (similar). Am I right?
Also - where can I check for the list of these kenel built-in modules? In /lib/modules I can see only these: $ pwd /lib/modules $ ls rtai_up.ko rtai_timer_start.ko rtai_hal.ko $
Where these i2c-*.o files should be kept, after inserted with insmod (or comiled staticaly into a kernel, as in my case).
Btw. lsmod gives me: $ lsmod Module Size Used by igmp_filter 11812 - - Live 0x70edc000 0x70edea80 0x70edeba8 linux_drv 6147776 - - Live 0x71000000 0x7106e5fc 0x7109aa00 rtai_timer_start 1136 - - Live 0x71c48000 0x71c483b7 0x71c48470 rtai_up 95340 - - Live 0x70ea0000 0x70eb5478 0x70eb5bc0 rtai_hal 32640 - - Live 0x71df0000 0x71df4a48 0x71df4b20
