PM1725 controllers have a couple of quirks that need to be handled in the driver: - I/O queue depth must be limited to 64 entries on controllers that do not report MQES. - The host interface registers go offline briefly while resetting the chip. Thus a delay is needed before checking whether the controller is ready. Note that the admin queue depth is also limited to 64 on older versions of this board. Since our NVME_AQ_DEPTH is now 32 that is no longer an issue. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Sagi Grimberg <sagi@grimberg.me>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
