17 Microcode Management
18 
19 Historically microcode files were delivered by Intel as a single
20 microcode file that we would break apart and install with ucodeadm. Each
21 individual file represented a single platform's microcode. However,
22 recently Intel has changed that policy and is no longer distributing
23 microcode in that fashion. Further, we also relied on bootadm to go
24 through and turn this microcode into individual files as part of setting
25 up the boot environment.
26 
27 Intead of using this method, we will update the microcode and manage
28 them in here as individual files. When updating files, please indicate
29 the release that the microcode was obtained from here.
30 
31 >>> Intel
32 
33 The upstream microcode for Intel can currently be found at:
34 
35     https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files
36 
37 The script "update.intel" in this directory can be used to help automate
38 the update by providing a tarball of the above microcode, and takes care
39 of updating the manifest as necessary. Be careful about new files.
40 
41 Intel - see:
42     usr/src/pkg/manifests/system-microcode-intel.p5m
43 for exact current version
44 
45 >>> AMD
46 
47 The upstream microcode for AMD can currently be found at:
48 
49     git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
50 
51 The script "update.amd" in this directory can be used to help automate
52 the update by automatically checking out the latest upstream firmware and
53 inserting it into the tree and package manifest. Be careful about new files.
54 
55 NOTE: If any microcode file is larger than 8KiB (8192 bytes), then the size of
56       the ucode_file_amd_t structure in uts/common/sys/ucode.h will need
57       increasing to cater for this.
58 
59 AMD - see:
60     usr/src/pkg/manifests/system-microcode-amd.p5m
61 for exact current version
