16*55908bd7SJohn LevonMicrocode Management
17*55908bd7SJohn Levon
18*55908bd7SJohn LevonHistorically microcode files were delivered by Intel as a single
19*55908bd7SJohn Levonmicrocode file that we would break apart and install with ucodeadm. 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.

30*55908bd7SJohn LevonThe upstream microcode for Intel can currently be found at:

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. Be careful about new files.
