摘要： Embodiments of this application disclose a system startup method and a related device. The method includes: creating a first thread when a kernel driver in a kernel mode detects a first disk partition; reading, in the kernel mode, metadata of the first disk partition by using the first thread; and writing the metadata of the first disk partition into a first page cache by using the first thread. In the kernel mode, metadata of a disk partition is pre-cached into a page cache by using the first thread, and in a subsequent process in a user mode, the metadata of the disk partition may be directly read from the page cache. A storage area of the page cache is memory and has a higher read/write operation rate compared with a disk. Therefore, congestion occurring when a system of a terminal device starts can be effectively avoided, and time required for system startup can be reduced.

摘要： This application provides a storage control method, and relates to the terminal field. At least one key IO is identified from a plurality of IOs, the at least one key IO is delivered to a hardware queue, and at least one non-key IO other than the at least one key IO in the plurality of IOs is delivered to the hardware queue through rate limiting. During the delivery through the rate limiting, a quantity of at least one non-key IO is less than a quantity of IOs that the hardware queue is able to contain. In the method, the key IO in the plurality of IOs is delivered to the hardware queue, and the non-key IO is delivered to the hardware queue through rate limiting, so that the entire IO delivery queue can not only maintain a sequence for execution, but also fully utilize the hardware queue. This avoids system suspension.
