Each 20*55908bd7SJohn Levonindividual file represented a single platform's microcode. However, 21*55908bd7SJohn Levonrecently Intel has changed that policy and is no longer distributing 22*55908bd7SJohn Levonmicrocode in that fashion. Further, we also relied on bootadm to go 23*55908bd7SJohn Levonthrough and turn this microcode into individual files as part of setting 24*55908bd7SJohn Levonup the boot environment. 25*55908bd7SJohn Levon 26*55908bd7SJohn LevonIntead of using this method, we will update the microcode and manage 27*55908bd7SJohn Levonthem in here as individual files. When updating files, please indicate 28*55908bd7SJohn Levonthe release that the microcode was obtained from here. 29*55908bd7SJohn Levon 30*55908bd7SJohn LevonThe upstream microcode for Intel can currently be found at: 31*55908bd7SJohn Levon 32*55908bd7SJohn Levonhttps://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files 33*55908bd7SJohn Levon 34*55908bd7SJohn LevonThe script "update.intel" in this directory can be used to help automate 35*55908bd7SJohn Levonthe update by providing a tarball of the above microcode, and takes care 36*55908bd7SJohn Levonof updating the manifest as necessary.
