Subject: [PATCH 1/2] habanalabs: change default CS timeout to 30 seconds
Date: Tue, 23 Feb 2021 00:08:41 +0200	[thread overview]
Message-ID: <20210222220842.9398-1-ogabbay@kernel.org> (raw)

Because our graph contains network operations, we need to account
for delay in the network.

5 seconds timeout per CS is not enough to account for that.
