  16 Microcode Management
  17 
  18 Historically microcode files were delivered by Intel as a single
  19 microcode file that we would break apart and install with ucodeadm. Each
  20 individual file represented a single platform's microcode. However,
  21 recently Intel has changed that policy and is no longer distributing
  22 microcode in that fashion. Further, we also relied on bootadm to go
  23 through and turn this microcode into individual files as part of setting
  24 up the boot environment.
  25 
  26 Intead of using this method, we will update the microcode and manage
  27 them in here as individual files. When updating files, please indicate
  28 the release that the microcode was obtained from here.

  30 The upstream microcode for Intel can currently be found at:
  31 
  32 https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files
  33 
  34 The script "update.intel" in this directory can be used to help automate
  35 the update by providing a tarball of the above microcode, and takes care
  36 of updating the manifest as necessary. Be careful about new files.
