https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202614 Bug ID: 202614 Summary: [EFI] boot/loader.efi: Fix and improve the 'nvram' command Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: ganael.laplanche@corp.ovh.com Created attachment 160296 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=160296&action=edit patch-sys-boot-efi-loader-main.c Hi, The embedded 'nvram' command of loader.efi (-CURRENT, r286279) fails to list EFI variables with the following message : ??=<error retrieving variable> Find attached a patch that brings the following : - Fix variables enumeration (to initiate the search, the 'VariableName' argument of GetNextVariableName() should be a pointer to NULL, not a NULL pointer [1]) - Add a '-v' (verbose) option to display variables' contents (now hidden by default, as the output is un-readable with too many variables) - Add the ability to specify a variable name to restrict display to variable(s) matching this name only - Print GUID along with each variable name - Simplify contents' rendering by *always* printing them in hex (most of the contents were un-readable in ascii) Best Regards, Ganael.
