+intel-microcode (3.20170511.1~deb8u1) jessie; urgency=high
+
+ * This is the same package as 3.20170511.1 from unstable/testing and
+ 3.20170511.1~bpo8+1, from jessie-backports. It has been present in
+ unstable since 2017-05-15, testing since 2017-05-26, and jessie-backports
+ since 2017-05-29.
+ * Urgency updated to high:
+ + Confirmed fix: nightmare-level Skylake erratum SKL150
+ + Confirmed: gcc may generate the code patterns that trigger SKL150
+ (unpredictable behavior). The OCaml community was hit by this erratum
+ and has been investigating the issue since 2017-01. It affected the
+ OCaml compiler, and OCaml programs when gcc was used as the backend.

+ + 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+ * source: remove superseded upstream data file: 20161104

+-- Microcode update instructions --
+This package contains Intel microcode files in two formats:
+* microcode.dat
+* intel-ucode directory
+
+microcode.dat is in a traditional text format. It is still used in some
+Linux distributions. It can be updated to the system through the old microcode
+update interface which is avaialble in the kernel with
+CONFIG_MICROCODE_OLD_INTERFACE=y.
+
+To update the microcode.dat to the system, one need:
+1. Ensure the existence of /dev/cpu/microcode
+2. Write microcode.dat to the file, e.g.
+ dd if=microcode.dat of=/dev/cpu/microcode bs=1M
+
+intel-ucode dirctory contains binary microcode files named in
+family-model-stepping pattern. The file is supported in most modern Linux
+distributions. It's generally located in the /lib/firmware directory,
+and can be updated throught the microcode reload interface.
+
+To update the intel-ucode package to the system, one need:
+1. Ensure the existence of /sys/devices/system/cpu/microcode/reload
+2. Copy intel-ucode directory to /lib/firmware, overwrite the files in
+/lib/firmware/intel-ucode/
+3. Write the reload interface to 1 to reload the microcode files, e.g.
+ echo 1 > /sys/devices/system/cpu/microcode/reload
