Subject: [RFC PATCH 3/5] arm: Remove 32bit KVM host support
Date: Mon, 10 Feb 2020 14:13:22 +0000	[thread overview]
Message-ID: <20200210141324.21090-4-maz@kernel.org> (raw)
In-Reply-To: <20200210141324.21090-1-maz@kernel.org>

That's it. Remove all references to KVM itself, and document
that although it is no more, the ABI between SVC and HYP still
exists.

 hypervisor), or any hypervisor-specific interaction when the kernel is

+Note: KVM/arm has been removed from the kernel. The API described
+here is still valid though, as it allows the kernel to kexec when
+booted at HYP. It can also be used by a hypervisor other than KVM
+if necessary.
+
 On arm and arm64 (without VHE), the kernel doesn't run in hypervisor
 mode, but still needs to interact with it, allowing a built-in
 hypervisor to be either installed or torn down.

Subject: [RFC PATCH 3/5] arm: Remove 32bit KVM host support
Date: Mon, 10 Feb 2020 14:13:22 +0000	[thread overview]
Message-ID: <20200210141324.21090-4-maz@kernel.org> (raw)
In-Reply-To: <20200210141324.21090-1-maz@kernel.org>

That's it. Remove all references to KVM itself, and document
that although it is no more, the ABI between SVC and HYP still
exists.
