Verbose operation (cumulative) Sets input file type for the next microcode files. The type is a single character: "b" (binary), "d" (Intel .dat), "r" (search inside unknown binary data), or "a" (type will be selected by filename suffix) Select microcodes by the specified signature and processor flags mask (pf_mask). Specify more than once to select/unselect more microcodes. Prefix with ! to unselect microcodes. Use -s ! to disable the default behavior of selecting all microcodes when no -s or -S filter is specified Select microcodes based on the running system processor(s). Can be combined with the -s option, and can be used only once. Microcodes selected by --scan-system can be unselected by a later -s !<signature> option Instead of discarding microcodes based on revision level, keep the one from the file loaded last. Files are loaded in the order they were specified in the command line Keep the microcode with the highest revision level, regardless of the file load order (default) Select only microcodes older than the specified date Select only microcodes newer than the specified date Consider for selection other revisions (outside of the date range) of every microcode that was selected within the date range Select only microcodes strictly within the date range (default) List selected microcode signatures Upload selected microcodes to the kernel. Optionally, the device path can be specified (default: /dev/cpu/microcode) Write selected microcodes with the filenames expected by the Linux kernel firmware loader. Optionally, the destination directory can be specified (default: /lib/firmware/intel-ucode) Write selected microcodes to a file in binary format. The binary format is suitable to be uploaded to the kernel Write selected microcodes to an early initramfs file, which should be prepended to the regular initramfs Write selected microcodes to files in the specified directory, in binary format. The file name will reflect the microcode signature, mask and revision Write every microcode to files in the specified directory, in binary format. The file name will reflect the microcode signature, mask and revision. This is the only way to write out every revision of a microcode Unlink (remove) destination files before writing Do not remove existing files (default) Optimize the early initramfs cpio container for minimal size. The microcode data file will not be available to the regular initramfs, and tools might complain about the non-standard cpio block size Write a normal-sized early initramfs (default) Perform strict checks on the microcode data (default) Perform less strict checks on the microcode data Skip broken microcode entries instead of aborting Abort on broken microcode entries (default) H(hx`H0 ppX@H write_cpio_trailer xx_write_cpio_hdrentry write_cpio_header write_intel_microcodes upload_intel_microcodes xx_process_ucode_signature_cb xx_process_ucode_entry_cb add_intel_microcode_bundle load_intel_microcode add_filter_to_list parse_u32 [[-t<type>] filename] ... iucode_tool - Tool to manipulate Intel IA32/X86_64 microcode bundles
The microcode bundle files should be specified as arguments. The bundle type is determined by the file name suffix. It defaults to the binary format.
Should the filename end with ".bin", binary mode will be used. Should the filename end with ".dat", text mode will be used. The -t option can be used to set the type of the microcode bundle files that come after it, e.g. -td /tmp/dat-file -tb /tmp/binary /tmp/binary2.
To load microcode data from stdin, use "-" as the filename. File type will be assumed to be text (".dat"), use option -tb to load binary data from stdin.
To load all files from a directory, specify the directory name. It will not recurse into subdirectories, they will be skipped.
Empty files and directories will be ignored, and will be skipped. https://gitlab.com/iucode-tool/iucode-tool/issues iucode_tool 2.1.1
