All the above patches enable usb 2.0 port power off mechanism. Usb 3.0

Reply for comment #13:
  I found iwlwifi-7265-8.ucode appears under /lib/firmware/, but the 12.04.4 OS 
can't recognize StonePeak card, and doesn't load wifi driver.
  So 12.04 can't support StonePeak. I will test StonePeak only on ubuntu 14.04.

  Wireless 3160 3.13+ kernel - iwlwifi-3160-ucode-22.15.8.0.tgz

  Quote from Emmanuel: OSVs can safely have both firmware files installed
  regardless of the kernel version. Kernel 3.10 won’t load 22.15.8.0 but 
22.1.7.0
  only. Kernel 3.13 will try to load 22.15.8.0 and if it is not there, it will
  try to load 22.1.7.0. So nothing bad will happen if OSVs have both firmware
  installed. Just a bit of a waste - but nothing worse than that.

[Kernel-packages] [Bug 1309415] Re: Ubuntu server 14.04 can't boot up after UEFI installation on Avoton-B0

[XiongZhang]

This is an issue afterwards UEFI installation. It is strange that you can see 
radeon firmware but I can't see any radeon firmware on my system.
I am using the ISO from http://www.ubuntu.com/download/server and under UEFI 
(not legacy) installation, there is no radeon firmware in /lib/firmware.

[Kernel-packages] [Bug 1309415] Re: Ubuntu server 14.04 can't boot up after UEFI installation on Avoton-B0

[XiongZhang]

Using the image your provided, I do legacy installation and UEFI installation 
on my system. Then I found many firmwares were missed after uefi installation.
You can compare the /lib/firmware between uefi installed system and legacy 
installed system.

[Kernel-packages] [Bug 1309415] Re: Ubuntu server 14.04 can't boot up after UEFI installation on Avoton-B0

[XiongZhang]

First I enable proposed repository, then I am dist-upgrade my system
which install linux-firmware package.  Next my system can boot up
normally. linux-meta-3.13.0.24.30 can  solve my issue.

But  how can I get a ISO installation image which contain this package ?
Without it, I think system still can't boot up default after uefi
installation.

Bug description:
  This is an Intel-specific feature.  When a USB port is powered off, VBUS is
  removed, and port events are lost (device connect  disconnect, remote wake
  from USB device suspend, and overcurrent events).  OEMs may power-gang several
  ports together, so VBUS may not be removed until several ports are powered 
off.

  The initialization of the PHY on I217/I218, while similar to 82579, must
  also check to see if the MAC and PHY are in the same mode (PCIe vs. SMBus)
  otherwise the PHY will be inaccessible by the MAC.

  Quote from Emmanuel: OSVs can safely have both firmware files installed
  regardless of the kernel version. Kernel 3.10 won’t load 22.15.8.0 but 
22.1.7.0
  only. Kernel 3.13 will try to load 22.15.8.0 and if it is not there, it will
  try to load 22.1.7.0. So nothing bad will happen if OSVs have both firmware
  installed. Just a bit of a waste - but nothing worse than that.

Status in Dell Sputnik:

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  (This is a public bug report for LP1402828.)

  This system has a dual-mode audio with an HDA and an I2S interface.
  Which shows up depends on the reported _OSI from the last cold boot.
  Since the kernels in Ubuntu 14.10/15.04 (15.04 uses 3.18 currently)
  report an _OSI of Windows 2013, I2S mode is used for audio.

  A workaround is to pass acpi_os=!Windows 2013 as a kernel parameter,
  but this is non-optimal since the mode of the touchpad is affected. It
  also results in an alternate, less used and tested path in the
  firmware to be used.

  See the attached dmesg log for details on where the failure happens.
  Notably,

  $ dmesg -t | egrep (audio|snd|INT3438)

[XiongZhang]

Public bug reported:

 SRU Justification:
 On all of Intel's shipping xHCI platforms, including both servers and clients, 
the controller can cause the shutdown process to hang.
  This is because existing Intel xHCI controllers require a delay of 1 mS,after 
setting the CMD_RESET bit in command register, before accessing any HC 
registers. This allows the HC to complete the reset operation and be ready for 
HC register access.

Fix:
Patch in 4.4-rc2
commit a5964396190d0c40dd549c23848c282fffa5d1f2
Author: Rajmohan Mani 
Date:   Wed Nov 18 10:48:20 2015 +0200

xhci: Workaround to get Intel xHCI reset working more reliably

Regression Potential: Just add a 1ms delay for xhci_reset, so
regressions are very unlikely.

** Affects: linux (Ubuntu)
 Importance: Undecided
 Status: New

  Issue: 
  Between upstream kernel v3.19 to v4.2,when Intel SMEP/SMAP protection was 
triggered by some wild function call or data access,  the screen would be 
frozen and never come back,but the system does not hang.

  Generally, an SMEP/SMAP violation should cause the involved process
  killed, an oops from page fault exception generated to the syslog, and
  the system survived.

  Fix:
  One patch from 4.3 kernel fix this issue

[Kernel-packages] [Bug 1398274] Re: [Feature] TPM2.0 kernel support

[XiongZhang]

Sorry, I have to add more commits for TPM 2.0 trusted keys.
In v4.5 kernel:
6674ff1 tpm_ibmvtpm: properly handle interrupted packet receptions
b8ba1e7 tpm_tis: Tighten IRQ auto-probing
e3837e7 tpm_tis: Refactor the interrupt setup
7ab4032 tpm_tis: Get rid of the duplicate IRQ probing code
2511204 tpm: rework tpm_get_timeouts()
036bb38 tpm_tis: Ensure interrupts are disabled when the driver starts
727f28b tpm_tis: Use devm_free_irq not free_irq
f728643 tpm_tis: further simplify calculation of ordinal duration

There are also some bug fixes patches queued in maintainer's tree for v4.6. 
Once 4.6-rc1 is released, we will give the commits.
If 16.04 couldn't wait for 4.6-rc1,  16.04 should pick this fixes at least 
which will be in 4.5.1 stable.

Bug description:
  USB core expects the roothubs to support the same requests and descriptors as 
external hubs. As the two roothubs (USB2 and USB3) are
  part of xhci we need to support  the descriptor and request changes in 
USB3.1. In our case we need to:
  1)Fill and return the new SuperSpeedPlus USB Device capability descriptor as 
part of the BOS (Binary device Object Store) descritptor. The speed info needed 
to fill this descriptor can be parsed from extended capability, supported 
protocol PSI lists. (see xhci 1.1 section 7.2)
  2)Return the new EXT_PORT_STATUS when usb core requests a   get_port_status() 
with new option. Can be read from xhci PORTSC register speed field, and map it 
to the PSI in the extended capability.Optionally check it from slot output 
context?
  3) Check if usb core stored SSP (SuperSpeedPlus) isoc endpointcompanion 
data with the endpoint and use it to calculate max packets and bandwidth.

[XiongZhang]

We should defer it to 17.04 as new interface is queued in linux-next as
part of v4.9

** Description changed:

  Memory Protection Keys for Userspace (PKU aka PKEYs) is a Skylake-SP server 
feature that provides a mechanism for enforcing page-based protections, but 
without requiring modification of the page tables when an application changes 
protection domains.  It works by dedicating 4 previously ignored bits in each 
page table entry to a "protection key", giving 16 possible keys.
  There is also a new user-accessible register (PKRU) with two separate bits 
(Access Disable and Write Disable) for each key.Being a CPU register, PKRU is 
inherently thread-local,potentially giving each thread a different set of 
protectionsfrom every other thread.
  There are two new instructions (RDPKRU/WRPKRU) for reading and writing to the 
new register.  The feature is only available in 64-bit mode, even though there 
is theoretically space in the PAE PTEs.  These permissions are enforced on data 
access only and have no effect on instruction fetches.

Status in intel:
  New
Status in linux package in Ubuntu:
  Incomplete
Status in xen package in Ubuntu:
  Fix Released

Bug description:
  Code Data prioritization (CDP) is projected to be released before the 
MBE(memory b/w enforcement) as part of bdx
  This would be an extension of the CAT feature and the h/w would provide cache 
allocation for code and data seperately once the feature is enabled. This is 
added from customer requests who have very large code footprints and need to 
seperately prioritize data and code.

  Posted Interrupts on Broadwell is really VT-d posted interrupts.
  Posted Interrupts for the processor are part of the APIC-V and was
  introduced in IVT. The idea is that the interrupt can be placed in a
  data structure for the guest and the guest can, under the right
  conditions, receive the interrupt without VM exiting. Chapter 29 of
  vol. c of the SDM has the currently public part of posted interrupts.

  RDTSC scaling is a new virtualization feature that applies a scaling

  rate while in a VM, even though the underlying hardware is counting at
  a differing TSC rate.

  [Feature] Purley: Memory Protection Keys

Status in intel:
  New
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Memory Protection Keys for Userspace (PKU aka PKEYs) is a Skylake-SP server 
feature that provides a mechanism for enforcing page-based protections, but 
without requiring modification of the page tables when an application changes 
protection domains.  It works by dedicating 4 previously ignored bits in each 
page table entry to a "protection key", giving 16 possible keys.
  There is also a new user-accessible register (PKRU) with two separate bits 
(Access Disable and Write Disable) for each key.Being a CPU register, PKRU is 
inherently thread-local,potentially giving each thread a different set of 
protectionsfrom every other thread.
  There are two new instructions (RDPKRU/WRPKRU) for reading and writing to the 
new register.  The feature is only available in 64-bit mode, even though there 
is theoretically space in the PAE PTEs.  These permissions are enforced on data 
access only and have no effect on instruction fetches.

  HW: Purley

  Upstream status:
  v4.6 kernel implement basic and execute-only support

[Kernel-packages] [Bug 1643087] Re: Yakkety failures on Xeon Phi (Dell Poweredge C6320p)

[XiongZhang]

The microcode on DELL KNL-D machine is 0x01a0, while our SDV is
0x01a3. So it is possible to upgrade bios first.

Another strange thing in cpuinfo is cpu frequency is 998.962MHz, why is
it not 1.3GHz ?
