* cpucontrol: check for the supposed firmware file type and skipKonstantin Belousov2019-01-111-0/+2
| | | | | | | | | | | | | | | | non-regular entry. do_update() skips entries with DT_DIR type. This does not eliminate other entries that might exist in the directory. More, since NFS might fill d_type with DT_UNKNOWN, dot and dotdot entries are not skipped, then mmap(2) call failed for them when update microcode files are located on NFS.

* cpucontrol(8): De-duplicate common update logicConrad Meyer2018-11-146-228/+183
| | | | | | | | | | | | | Every µcode-updater must open the cpucontrol devfs node RDWR, open a firmware file, validate the FW file has a positive length, mmap it, etc. De-duplicate that identical logic between every individual platform. Also, constify references to the readonly-mapped firmware files while here. Sponsored by: Dell EMC Isilon Notes: svn path=/head/; revision=340421

* Make it possible to re-evaluate cpu_features.Konstantin Belousov2018-01-052-24/+69
| | | | | | | | | | | | | | | | | | | Add cpuctl(4) ioctl CPUCTL_EVAL_CPU_FEATURES which forces re-read of cpu_features, cpu_features2, cpu_stdext_features, and std_stdext_features2. The intent is to allow the kernel to see the changes in the CPU features after micocode update. Of course, the update is not atomic across variables and not synchronized with readers. See the man page warning as well.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-278-0/+16
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

Explain the default path behavior, list default path. Correct example of update performed from the non-default path, it needs -n and the trailing slash is redundand. Remove useless BUGS section.

If newer microcode files are put into non-standard path, both measures allow to avoid situation where older update loaded from the default path first, and then the second update is applied from non-standard path. Applying intermediate updates might be undesirable. Sponsored by: The FreeBSD Foundation MFC after: 1 week Notes: svn path=/head/; revision=324113

Two new operations ("&=" and "|=") have been added. The first one applies bitwise AND operaion between the current contents of the MSR register and the mask, and the second performs bitwise OR. The argument can be optionally prefixed with "~" inversion operator. This allows one to mimic the "clear bit" behavior by using the command like this: cpucontrol -m 0x10&=~0x02 # clear the second bit of TSC MSR Inversion operator support in all modes (assignment, OR, AND).
