* Implement {io,admin}-passthru commands.Warner Losh2019-07-161-0/+273
| | | | | | | | | | | | | | | | | These are mostly compatible with Linux, with three exceptions. 1. We don't do metadata segment stuff. Our passthrough interface doesn't cope. The code is there, but generates an error. 2. Linux lets you specify a namespace ID for the command. We current do not: we get ours from the namespace device, or pass in a generic one. Generally, this will lead to the same command, but FreeBSD's is safer since you can't specify the wrong id. 3. --show-command outputs to stderr instead of stdout so you can both see your command, and capture its output with a simple redirect.

* Create generic command / arg parsing routinesWarner Losh2019-07-1615-813/+1267
| | | | | | | | | | | | | | | | | | | | | Create a set of routines and structures to hold the data for the args for a command. Use them to generate help and to parse args. Convert all the current commands over to the new format. "comnd" is a hat-tip to the TOPS-20 %COMND JSYS that (very) loosely inspired much of the subsequent command line notions in the industry, but this is far simpler (the %COMND man page is longer than this code) and not in the kernel... Also, it implements today's de-facto command [verb]+ [opts]* [args]* format rather than the old, archaic TOPS-20 command format :) This is a snapshot of a work in progress to get the nvme passthru stuff committed. In time it will become a private library and used by some other programs in the tree that conform to the above pattern.

| | | | | | | | | | | | | Move from using a linker set to a constructor function that's called. This simplifies the code and is slightly more obvious. We now keep a list of page decoders rather than having an array we managed before. Commands will move to something similar in the future.

* Move nvmecontrol to using linker sets for commandsWarner Losh2018-12-0212-96/+103
| | | | | | | | | | | | | | | | | More commands will be added to nvmecontrol. Also, there will be a few more vendor commands (some of which may need to remain private to companies writing them). The first step on that journey is to move to using linker sets to dispatch commands. The next step will be using dlopen to bring in the .so's that have the command that might need to remain private for seamless integration. Similar changes to this will be needed for vendor specific log pages. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D18403 Notes: svn path=/head/; revision=341407

* Make NVMe compatible with the original APIChuck Tuffli2018-08-227-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | The original NVMe API used bit-fields to represent fields in data structures defined by the specification (e.g. the op-code in the command data structure). The implementation targeted x86_64 processors and defined the bit fields for little endian dwords (i.e. 32 bits). This approach does not work as-is for big endian architectures and was changed to use a combination of bit shifts and masks to support PowerPC. Unfortunately, this changed the NVMe API and forces #ifdef's based on the OS revision level in user space code. This change reverts to something that looks like the original API, but it uses bytes instead of bit-fields inside the packed command structure. As a bonus, this works as-is for both big and little endian CPU architectures.

* Print Maximum Data Transfer Size as a long rather than intJustin Hibbits2018-06-071-1/+1
| | | | | | | | | | | | PowerPC has PAGE_SIZE as a long, not an int. This causes the compiler to throw a format mismatch warning on this print.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-278-0/+16
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.
