WebFile Operations. In the next few sections, we’ll look at the various operations a driver can perform on the devices it manages. An open device is identified internally by a file structure, and the kernel uses the file_operations structure to access the driver’s functions. The structure, defined in , is an array of function pointers. WebThis support is using the fwnode API which also works with device-tree and ACPI. For this purpose, the device-tree and ACPI code handling the i2c adapter retrieval was factorized with the new code. This also allows i2c devices using a software_node description to be used by sfp code.
