Subject: [PATCH v2 2/2] nvme-pci: Add TUXEDO IBP Gen9 to Samsung sleep quirk
Date: Mon, 16 Dec 2024 23:28:04 +0100	[thread overview]
Message-ID: <20241216223145.135942-2-wse@tuxedocomputers.com> (raw)
In-Reply-To: <20241216223145.135942-1-wse@tuxedocomputers.com>

From: Georg Gottleuber <ggo@tuxedocomputers.com>

On the TUXEDO InfinityBook Pro Gen9 Intel, a Samsung 990 Evo NVMe leads to
a high power consumption in s2idle sleep (4 watts).

This patch applies 'Force No Simple Suspend' quirk to achieve a sleep with
a lower power consumption, typically around 1.2 watts.
