Subject: [PATCH v8 003/103] KVM: Refactor CPU compatibility check on module initialization
Date: Sun, 7 Aug 2022 15:00:48 -0700 [thread overview]
Message-ID: <4092a37d18f377003c6aebd9ced1280b0536c529.1659854790.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1659854790.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
TDX module requires its initialization. It requires VMX to be enabled.
Although there are several options of when to initialize it, the choice is
the initialization time of the KVM kernel module. There is no usable
arch-specific hook for the TDX module to utilize during the KVM kernel module
initialization. The code doesn't enable/disable hardware (VMX in TDX case)
during the kernel module initialization. Add a hook for enabling hardware,
arch-specific initialization, and disabling hardware during KVM kernel
module initialization to make a room for TDX module initialization. The
current KVM enables hardware when the first VM is created and disables
hardware when the last VM is destroyed. When no VM is running, hardware is
disabled. To follow these semantics, the kernel module initialization needs
to disable hardware. Opportunistically refactor the code to enable/disable
hardware.
Add hadware_enable_all() and hardware_disable_all() to kvm_init() and
introduce a new arch-specific callback function,
kvm_arch_post_hardware_enable_setup, for arch to do arch-specific
initialization that requires hardware_enable_all(). Opportunistically,
move kvm_arch_check_processor_compat() to to hardware_enabled_nolock().
TDX module initialization code will go into
kvm_arch_post_hardware_enable_setup().
This patch reorders some function calls as below from (*) (**) (A) and (B)
to (A) (B) and (*). Here (A) and (B) depends on (*), but not (**). By
code inspection, only mips and VMX has the code of (*). No other
arch has empty (*). So refactor mips and VMX and eliminate the
necessity hook for (*) instead of adding an unused hook.
Before this patch:
- Arch module initialization
- kvm_init()
- kvm_arch_init()
- kvm_arch_check_processor_compat() on each CPUs
- post-arch-specific initialization -- (*): (A) and (B) depends on this
- post-arch-specific initialization -- (**): no dependency to (A) and (B)
- When creating/deleting the first/last VM
- kvm_arch_hardware_enable() on each CPUs -- (A)
- kvm_arch_hardware_disable() on each CPUs -- (B)
After this patch:
- Arch module initialization
- kvm_init()
- kvm_arch_init()
- arch-specific initialization -- (*)
- kvm_arch_check_processor_compat() on each CPUs
- kvm_arch_hardware_enable() on each CPUs -- (A)
- kvm_arch_hardware_disable() on each CPUs -- (B)
- post-arch-specific initialization -- (**)
- When creating/deleting the first/last VM (no logic change)
- kvm_arch_hardware_enable() on each CPUs -- (A)
- kvm_arch_hardware_disable() on each CPUs -- (B)
Code inspection result:
As long as I inspected, I found only mips and VMX have non-empty (*) or
non-empty (A) or (B).
x86: tested on a real machine
mips: compile test only
powerpc, s390, arm, riscv: code inspection only
- arch/mips/kvm/mips.c
module init function, kvm_mips_init(), does some initialization after
kvm_init(). Compile test only.
- arch/x86/kvm/x86.c
- uses vm_list which is statically initialized.
- static_call(kvm_x86_hardware_enable)();
- SVM: (*) and (**) are empty.
- VMX: initialize percpu variable loaded_vmcss_on_cpu that VMXON uses.
- arch/powerpc/kvm/powerpc.c
kvm_arch_hardware_enable/disable() are nop
- arch/s390/kvm/kvm-s390.c
kvm_arch_hardware_enable/disable() are nop
- arch/arm64/kvm/arm.c
module init function, arm_init(), calls only kvm_init().
(*) and (**) are empty
- arch/riscv/kvm/main.c
module init function, riscv_kvm_init(), calls only kvm_init().
(*) and (**) are empty
