Subject: [RFC PATCH 3/9] rust: dma_fence: add method to return an indication if the fence is signaled
Date: Fri, 17 Mar 2023 09:12:07 -0300 [thread overview]
Message-ID: <20230317121213.93991-4-mcanal@igalia.com> (raw)
In-Reply-To: <20230317121213.93991-1-mcanal@igalia.com>
To indicate the current status of the fence, there is a kernel function that
returns an indication if the fence is signaled yet. Therefore, add a method
in the Rust abstraction to return an indication if the fence is signaled.
