xnvme_spec_ctrlr_bar

struct xnvme_spec_ctrlr_bar

libxnvme_spec - NVMe structs, enum, values and helper function declarations

If an entity is defined in the NVMe specification, then an enum or struct should exist in this header file. The purpose of this is to provide a single point of entry for spec. definitions for the purpose of providing structs with accessors, possibly bit-fields, and enums for values such as command opcodes.

Auxilary header files are provided for the different IO command-sets, e.g. libxnvme_nvm.h, providing utility functions such as xnvme_nvm_read, xnvme_nvm_write, and similarly libxnvme_znd.h with utilities such as xnvme_znd_append, xnvme_znd_mgmt_send. These can also contain enums and structs, however, these are not based on definitions in the NVMe specification, rather, these build on the spec. definition in order to provide something sligthly more convenient to the user.

A special class of utility functions are pretty-printers, all spec. defintions have two associated pretty-printers named by the type, suffixed by _fpr and _pr, for example:

  • xnvme_spec_cpl_fpr(), prints the given struct xnvme_spec_cpl struct to the given fstream

  • xnvme_spec_cpl_pr(), prints the given struct xnvme_spec_cpl struct to stdout

These functions are auto-generated and available by importing libxnvme_spec_pp.h. Thus, when you see a definition in libxnvme_spec.h then you can count on always having a textual representation available for that definition by importing libxnvme_spec_pp.h. You can also choose to add the libxnvme_pp.h which includes pretty-printers for all enums and struct known by xNVMe.
