![]() 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 <i@ibugone.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Keith Busch <kbusch@kernel.org> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
