[Bug 1386257] Re: intel-microcode should be installed by default, when the CPU is GenuineIntel

[Dimitri John Ledkov]

@debfx this is precisely why intel microcode package should be
consistently installed and this is done in response to the TSX problem
described before. microcode update is the last resort that vendor has to
correct firmware bugs in the field. microcode update removed TSX
instruction because the implementation turned out to have issues. But
that was not sufficient alone, due to incorrect detection in the user-
space code and the fact that microcode is not updated on most client
systems. This one of the corrective actions going forward to mitigate /
contain similar type of problem in the future.

Title:
  intel-microcode should be installed by default, when the CPU is
  GenuineIntel

Status in intel:
  New
Status in ubuntu-drivers-common package in Ubuntu:
  In Progress
Status in ubuntu-meta package in Ubuntu:
  In Progress

Bug description:
  intel-microcode should be installed by default on the bare-metal
  systems which are running on GenuineIntel CPUs, by the installers.

  Similarly other microcode packages for other CPUs brands should be
  considered for inclusion (e.g. amd64-microcode).

  I hope that ubuntu-drivers-common can gain ability to detect cpu
  series and/or vendors, packages that provide microcodes similarly
  declare support for cpu series and/or vendors, the microcode packages
  are shipped on the CDs in the pool directory, and installed on to the
  target machines as part of the installation.

  This should help with rapid correction of bugs and behaviour of the
  CPUs in the field.
