[PATCH OLK-6.6 1/2] KVM: arm64: Add runtime switch for TLBI DVMBM feature
by lishusen 09 Nov '26

09 Nov '26

From: lishusen <lishusen2(a)h-partners.com> Unify the two DVMBM control switches so that tlbi_dvmbm_enable is the single runtime switch, initialized from the cmdline parameter kvm-arm.dvmbm_enabled at KVM init time. With this change, kvm-arm.dvmbm_enabled=1 automatically sets tlbi_dvmbm_enable=1, and the DVMBM feature state is consistent with tlbi_dvmbm_enable (/sys/module/kvm/parameters/tlbi_dvmbm_enable). --- arch/arm64/kvm/arm.c | 12 +++++++++- arch/arm64/kvm/hisilicon/hisi_virt.c | 36 ++++++++++++++++++++++++---- arch/arm64/kvm/hisilicon/hisi_virt.h | 16 +++++++++++++ 3 files changed, 59 insertions(+), 5 deletions(-) diff --git a/arch/arm64/kvm/arm.c b/arch/arm64/kvm/arm.c index 9319d1b72239..921a0a9150a1 100644 --- a/arch/arm64/kvm/arm.c +++ b/arch/arm64/kvm/arm.c @@ -105,6 +105,16 @@ static const struct kernel_param_ops force_wfi_trap_ops = { bool force_wfi_trap; module_param_cb(force_wfi_trap, &force_wfi_trap_ops, &force_wfi_trap, 0644); +static const struct kernel_param_ops tlbi_dvmbm_enable_ops = { + .set = dvmbm_enable_update, + .get = param_get_bool, +}; + +bool tlbi_dvmbm_enable = false; +MODULE_PARM_DESC(tlbi_dvmbm_enable, "bool"); +module_param_cb(tlbi_dvmbm_enable, &tlbi_dvmbm_enable_ops, &tlbi_dvmbm_enable, + 0644); + static int vcpu_req_reload_wfi_traps(const char *val, const struct kernel_param *kp) { struct kvm *kvm; @@ -3569,7 +3579,7 @@ static __init int kvm_arm_init(void) kvm_ncsnp_support = hisi_ncsnp_supported(); kvm_dvmbm_support = hisi_dvmbm_supported(); kvm_info("KVM ncsnp %s\n", kvm_ncsnp_support ?
