* Regularize the Netflix copyrightWarner Losh2019-02-044-5/+2
| | | | | | | | | | | | | | | Use recent best practices for Copyright form at the top of the license: 1. Remove all the All Rights Reserved clauses on our stuff. Where we piggybacked others, use a separate line to make things clear. 2. Use "Netflix, Inc." everywhere. 3. Use a single line for the copyright for grep friendliness. 4. Use date ranges in all places for our stuff. Approved by: Netflix Legal (who gave me the form), adrian@ (pmc files) Notes: svn path=/head/; revision=343755

* Implenent --fromfile to read variable values when printing variablesWarner Losh2018-10-262-9/+42
| | | | | | | | | | | | | | | So ./efivar --fromfile Boot0001.bin --print --load-option will take the value from Boot0001.bin file and then decode it as if it were a load-option. This is useful for debugging handling of such variables that may be hanging the boot for some people. Sponsored by: Netflix, Inc Notes: svn path=/head/; revision=339797

* Simplify the efivar interface a little.Warner Losh2017-11-101-1/+1
| | | | | | | | | | | | | | | | | | | | We started out having Linux compatible libefivar interfaces. This was in anticipation of porting the GPL'd efibootmgr to FreeBSD via a port. However, since we need that functionality in the base, that port isn't going to happened. It also appears that efivar is a private library that's not used much outside a command line util and efibootmgr. Reduce compatibility with the Linux version a little by removing the mode parameter to efi_set_variable (which was unused on FreeBSD, and not set to something useful in the code we'd written). Also remove some efi error routines that were never implemented and existed only to placate early GPL efibootmgr porting experiments.

* Create efi utility printing routinesWarner Losh2017-09-074-81/+234
| | | | | | | | | | | | Split out asciidump, utf8dump, bindump, and hexdump into a separate file efiutil.c. Implement new efi_print_load_option for printing out the EFI_LOADER_OPTION data structure used to specify different options to the UEFI boot manager.

* Add UCS2->UTF8 option.Warner Losh2017-08-313-2/+37
| | | | | | | | | | Many UEFI variables are UCS2 strings (some NUL terminated, others not). Add --utf8 (-u) to convert UCS2 strings to UTF8 before printing. Sponsored by: Netflix Notes: svn path=/head/; revision=323066

* Finish implementing -d/--device/--device-path flag to print variableWarner Losh2017-03-092-16/+37
| | | | | | | | | | | | | | | as if it were a device path. Remove language about a=b syntax on the command line. This will not be implemented due to its limited usefulness. UEFI variables are binary blobs, on the whole, and a simple work around exists for strings. Clarify that the new value of the variable is taken from stdin. Update manual with history.
