I just built 3.7.9 for an x86_64 target. I had
CONFIG_IKCONFIG=m
# CONFIG_IKCONFIG_PROC is not set
but when I booted the kernel I modprobed configs.ko, /proc/configs does not show up...
Any ideas what's going on here? Previously I had IKCONFIG_PROC set and /proc/configs.gz shows up.. but odd that the uncompressed version doesn't work? _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD

The first option only stores the config within the kernel, you need the second option to access it via /proc (see http://cateee.net/lkddb/web-lkddb/IKCONFIG.html how to access it without /proc) |

The weird part I don't understand if that's the only way to access it, is if building this as a module, that data is not in the kernel and cannot be extracted in that manner. Thus it sort of "useless" to build it as a module and not select the /proc/config.gz option under it...
Oh well, thanks, was wondering if I was overlooking something but it would be nice if Kconfig mentioned to never build IKCONFIG as 'm' if IKCONFIG_PROC is not also set. _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD
