v2.3.1

2.3.1 - Maintenance release to address issue discovered with creation of temporary directory in some environments.

Fix:

• 2.3.0 creates a temporary directory in the same directory as the svr-info binary. When svr-info is installed by an administrator into a directory where a "regular" user cannot create a directory, an error will occur.
• The -temp CLI option has been repurposed to override the location of the local temporary directory.
• A new CLI option -targettemp is available to override the location of the temporary directory on the local or remote target.

v2.3.0

2.3.0

Features Added

• Now an all-inclusive single binary (svr-info) for easy re-location
  • to execute the reporter: ./svr-info -reporter ""
  • to execute the collector: ./svr-info -collector ""
• Connect to remote machines where keys are configured in ssh-agent
• Version tag added to all report types in new "svr-info" table.
• Differentiate SPR XCC and MCC SKUs
• Support added for Intel Emerald Rapids CPUs
• Recognize Intel Sierra Forest CPUs

• Differentiate CPU support vs. Platform support for an ISA

Bugs Fixed

• CXL menu link now navigates to the CXL table
• Remote data collection now stopped when svr-info stopped, e.g., with Ctrl-C
• Output data corruption due to over-aggressive filtering fixed
• DIMM population chart fixed for SuperMicro SPR
