From: Roland McGrath Date: Wed, 30 Jan 2008 12:30:54 +0000 (+0100) Subject: x86: debugctlmsr kconfig X-Git-Tag: v2.6.25-rc1~1143^2~689 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0a049bb0ab807b4a95dce9cd0b603c01c199a287;p=pandora-kernel.git x86: debugctlmsr kconfig This adds the (internal) Kconfig macro CONFIG_X86_DEBUGCTLMSR, to be defined when configuring to support only hardware that definitely supports MSR_IA32_DEBUGCTLMSR with the BTF flag. The Intel documentation says "P6 family" and later processors all have it. I think the Kconfig dependencies are right to have it set for those and unset for others (i.e., when 586 and earlier are supported).
