intel-microcode (3.20170511.1~ubuntu17.04.0) zesty; urgency=medium
* Backport of new upstream microde release to address Hyper Threading
bug. LP: #1700373.
intel-microcode (3.20170511.1) unstable; urgency=medium
* New upstream microcode datafile 20170511
+ Updated Microcodes:

sig 0x000506e3, pf_mask 0x36, 2017-04-09, rev 0x00ba, size 98304
+ This release fixes undisclosed errata on the desktop, mobile and
server processor models from the Haswell, Broadwell, and Skylake
families, including even the high-end multi-socket server Xeons
+ Likely fix the TSC-Deadline LAPIC errata (BDF89, SKL142 and
similar) on several processor families
+ Fix erratum BDF90 on Xeon E7v4, E5v4(?) (closes: #862606)
+ Likely fix serious or critical Skylake errata: SKL138/144,
SKL137/145, SLK149
* Likely fix nightmare-level Skylake erratum SKL150. Fortunately,
either this erratum is very-low-hitting, or gcc/clang/icc/msvc
won't usually issue the affected opcode pattern and it ends up
being rare.
SKL150 - Short loops using both the AH/BH/CH/DH registers and
the corresponding wide register *may* result in unpredictable
system behavior. Requires both logical processors of the same
core (i.e. sibling hyperthreads) to be active to trigger, as
well as a "complex set of micro-architectural conditions"
* source: remove unneeded intel-ucode/ directory
Since release 20170511, upstream ships the microcodes both in .dat
format, and as Linux-style split /lib/firmware/intel-ucode files.
It is simpler to just use the .dat format file for now, so remove
the intel-ucode/ directory. Note: before removal, it was verified
that there were no discrepancies between the two microcode sets
(.dat and intel-ucode/)
* source: remove superseded upstream data file: 20161104
