Subject: [PATCH v3 17/20] ui: Add egl helpers for synchronization
Date: Tue, 11 May 2021 01:08:15 -0700	[thread overview]
Message-ID: <20210511080818.366985-18-vivek.kasireddy@intel.com> (raw)
In-Reply-To: <20210511080818.366985-1-vivek.kasireddy@intel.com>

These egl helpers will be useful for creating a sync object
and waiting on it when called from the virtio-gpu wait_flush
API.
