Subject: [PATCH hyperv-next v3 10/15] Drivers: hv: Rename the SynIC enable and disable routines
Date: Tue, 3 Jun 2025 17:43:36 -0700 [thread overview]
Message-ID: <20250604004341.7194-11-romank@linux.microsoft.com> (raw)
In-Reply-To: <20250604004341.7194-1-romank@linux.microsoft.com>
The confidential VMBus requires support for the both hypervisor
facing SynIC and the paravisor one.
Rename the functions that enable and disable SynIC with the
hypervisor.
