Subject: Can't remove CONFIG_GENERIC_CMOS_UPDATE, CONFIG_X86_TSC from kernel configuration
Date: Tue, 14 Oct 2014 11:34:43 +0200	[thread overview]
Message-ID: <29345_1413279277_543CEE2C_29345_1230_1_FDF2BCC5A347C04C96E55A31D54D9D510899DC6808@THSNCOA06MXS02P.ONE-06.GRP> (raw)

I want to rebuild linux-3.16.3-200.fc20.x86_64 with options:
CONFIG_GENERIC_CMOS_UPDATE=n
CONFIG_X86_TSC=n

But it seams that "make olddefconfig" enables these options again because of dependencies.

I found the "select GENERIC_CMOS_UPDATE" entries in  arch/*/Kconfig files - if I remove them, I am able to build a kernel with CONFIG_GENERIC_CMOS_UPDATE=n.
It's selected by default but does not seam to be necessary isn't it?

I am not able to disable CONFIG_X86_TSC.
It seams that Xen (arch/x86/xen/Kconfig) depends on X86_TSC - so I disabled all the XEN stuff.
May arch/x86/Kconfig.cpu (config X86_TSC - def_bool y) is the reason that CONFIG_X86_TSC is enabled again?
I thought it's just on of multiple clock sources isn't it?

It's my first email to a kernel mailing list so please be clement - feetback welcome. :-)

Mit freundlichen Grüßen/Best regards
