Subject: [PATCH] nvme-pci: avoid the deepest sleep state on ZHITAI TiPro5000 SSDs
Date: Wed, 28 Sep 2022 17:39:13 +0800 [thread overview]
Message-ID: <20220928093913.45905-1-xry111@xry111.site> (raw)
ZHITAI TiPro5000 SSDs has the same APST sleep problem as its cousin,
TiPro7000. The quirk for TiPro7000 has been added in
commit 6b961bce50e4 ("nvme-pci: avoid the deepest sleep state on
ZHITAI TiPro7000 SSDs"), use the same quirk for TiPro5000.
The ASPT data from "nvme id-ctrl /dev/nvme1":
vid : 0x1e49
ssvid : 0x1e49
sn : ZTA21T0KA2227304LM
mn : ZHITAI TiPlus5000 1TB
