From: Sean Christopherson Date: Mon, 18 Nov 2024 17:20:02 +0000 (-0800) Subject: KVM: x86: Break CONFIG_KVM_X86's direct dependency on KVM_INTEL || KVM_AMD X-Git-Tag: microblaze-v6.16~477^2~3 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=9ee62c33c0fe017ee02501a877f6f562363122fa;p=linux-2.6-microblaze.git KVM: x86: Break CONFIG_KVM_X86's direct dependency on KVM_INTEL || KVM_AMD Rework CONFIG_KVM_X86's dependency to only check if KVM_INTEL or KVM_AMD is selected, i.e. not 'n'. Having KVM_X86 depend directly on the vendor modules results in KVM_X86 being set to 'm' if at least one of KVM_INTEL or KVM_AMD is enabled, but neither is 'y', regardless of the value of KVM itself. The documentation for def_tristate doesn't explicitly state that this is the intended behavior, but it does clearly state that the "if" section is parsed as a dependency, i.e. the behavior is consistent with how tristate dependencies are handled in general. Optionally dependencies for this default value can be added with "if".
