Currently, secondary execution controls are divided in three groups: - static, depending mostly on the module arguments or the processor (vmx_secondary_exec_control) - static, depending on CPUID (vmx_cpuid_update) - dynamic, depending on nested VMX or local APIC state Because walking CPUID is expensive, prepare_vmcs02 is using only the first group. This however is unnecessarily complicated. Just cache the static secondary execution controls, and then prepare_vmcs02 does not need to compute them every time. Computation of all static secondary execution controls is now kept in a single function, vmx_compute_secondary_exec_control. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
