From: Jiawei Fu (iBug) Date: Fri, 15 Mar 2024 19:27:49 +0000 (+0800) Subject: drivers/nvme: Add quirks for device 126f:2262 X-Git-Tag: v6.9-rc1~13^2^2~4 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e89086c43f05;p=thirdparty%2Flinux.git drivers/nvme: Add quirks for device 126f:2262 This commit adds NVME_QUIRK_NO_DEEPEST_PS and NVME_QUIRK_BOGUS_NID for device [126f:2262], which appears to be a generic VID:PID pair used for many SSDs based on the Silicon Motion SM2262/SM2262EN controller. Two of my SSDs with this VID:PID pair exhibit the same behavior: * They frequently have trouble exiting the deepest power state (5), resulting in the entire disk unresponsive. Verified by setting nvme_core.default_ps_max_latency_us=10000 and observing them behaving normally. * They produce all-zero nguid and eui64 with `nvme id-ns` command. The offending products are: * HP SSD EX950 1TB * HIKVISION C2000Pro 2TB Signed-off-by: Jiawei Fu Reviewed-by: Christoph Hellwig Reviewed-by: Sagi Grimberg Signed-off-by: Keith Busch --- diff --git a/drivers/nvme/host/pci.c b/drivers/nvme/host/pci.c index e6267a6aa3801..8e0bb9692685d 100644 --- a/drivers/nvme/host/pci.c +++ b/drivers/nvme/host/pci.c @@ -3363,6 +3363,9 @@ static const struct pci_device_id nvme_id_table[] = { NVME_QUIRK_BOGUS_NID, }, { PCI_VDEVICE(REDHAT, 0x0010), /* Qemu emulated controller */ .driver_data = NVME_QUIRK_BOGUS_NID, }, + { PCI_DEVICE(0x126f, 0x2262), /* Silicon Motion generic */ + .driver_data = NVME_QUIRK_NO_DEEPEST_PS | + NVME_QUIRK_BOGUS_NID, }, { PCI_DEVICE(0x126f, 0x2263), /* Silicon Motion unidentified */ .driver_data = NVME_QUIRK_NO_NS_DESC_LIST | NVME_QUIRK_BOGUS_NID, },
