Subject: [PATCH V4 1/15] KVM: Add tlb_remote_flush_with_range callback in kvm_x86_ops
Date: Sat, 13 Oct 2018 22:53:52 +0800 [thread overview]
Message-ID: <20181013145406.4911-2-Tianyu.Lan@microsoft.com> (raw)
In-Reply-To: <20181013145406.4911-1-Tianyu.Lan@microsoft.com>
From: Lan Tianyu <Tianyu.Lan@microsoft.com>
Add flush range call back in the kvm_x86_ops and platform can use it
to register its associated function. The parameter "kvm_tlb_range"
accepts a single range and flush list which contains a list of ranges.
Signed-off-by: Lan Tianyu <Tianyu.Lan@microsoft.com>

Change since v1:
Change "end_gfn" to "pages" to aviod confusion as to whether
"end_gfn" is inclusive or exlusive.
