Ning Wang 6b961bce50 nvme-pci: avoid the deepest sleep state on ZHITAI TiPro7000 SSDs ... When ZHITAI TiPro7000 SSDs entered deepest power state(ps4) it has the same APST sleep problem as Kingston A2000. by chance the system crashes and displays the same dmesg info: https://bugzilla.kernel.org/show_bug.cgi?id=195039#c65 As the Archlinux wiki suggest (enlat + exlat) < 25000 is fine and my testing shows no system crashes ever since. Therefore disabling the deepest power state will fix the APST sleep issue. https://wiki.archlinux.org/title/Solid_state_drive/NVMe This is the APST data from 'nvme id-ctrl /dev/nvme1' NVME Identify Controller: vid : 0x1e49 ssvid : 0x1e49 sn : [...] mn : ZHITAI TiPro7000 1TB fr : ZTA32F3Y [...] ps 0 : mp:3.50W operational enlat:5 exlat:5 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:- active_power:- ps 1 : mp:3.30W operational enlat:50 exlat:100 rrt:1 rrl:1 rwt:1 rwl:1 idle_power:- active_power:- ps 2 : mp:2.80W operational enlat:50 exlat:200 rrt:2 rrl:2 rwt:2 rwl:2 idle_power:- active_power:- ps 3 : mp:0.1500W non-operational enlat:500 exlat:5000 rrt:3 rrl:3 rwt:3 rwl:3 idle_power:- active_power:- ps 4 : mp:0.0200W non-operational enlat:2000 exlat:60000 rrt:4 rrl:4 rwt:4 rwl:4 idle_power:- active_power:- Signed-off-by: Ning Wang <ningwang35@outlook.com> Signed-off-by: Christoph Hellwig <hch@lst.de>		2022-06-13 19:56:56 +02:00
