# This filter selects what we consider to be old microcode which
# should still be shipped even if Intel dropped them. Note that
# it is useless to ship microcodes for anything the distro doesn't
# really support anymore
#
# Watch out: check in the changelog, if this filter will add
# microcodes that look like they've been recalled, use IUC_EXCLUDE
# below to avoid shipping the probably recalled microcode.
# Last manual check: up to 2008-01-01

# EXCLUDING MICROCODES:
# Always document reason. See iucode_tool(8) for -s !<sig> syntax
# Recalls might require use of .fw overrides to retain old version,
# instead of exclusions. Exclusions have the highest priority, and
# will remove microcode added by any other means, including override
# files (.fw files).

# bundles, without the need for an override file. See iucode_tool(8)
