Message-Id: <20210521170653.4700-1-ogabbay@kernel.org> Date: Fri, 21 May 2021 20:06:50 +0300 From: Oded Gabbay <ogabbay@...nel.org> To: linux-kernel@...r.kernel.org Subject: [PATCH 1/4] habanalabs: set memory scrubbing to disabled by default Scrubbing memory after every unmap is very costly in terms of performance. If a user wants it he can enable it but the default should prioritize performance.
