2016-01-05 Thread William Grant

If you need avx2 support, --cpu Haswell-noTSX,-x2apic works on Haswell
desktop/laptop chips.

The most confusing problem is that qemu's definition of "Haswell" is
actually Haswell-E, -EP and -EX; Haswell itself lacks x2apic, which
qemu's Haswell requires. x2apic dates back to Nehalem, but qemu's CPU
definitions only include it back to Sandy Bridge, so a standard desktop
or laptop Haswell CPU falls all the back to Westmere and then adds flags
including avx, avx2 and xsave on top of that[0].

Advertising support for AVX and AVX2 is just a matter of setting
CPUID.1:ECX.AVX and CPUID.7:EBX.AVX2, but the instructions won't
actually work unless XCR0.AVX is set, and kvm_load_guest_xcr0 only sets
XCR0 from the guest if the guest's XR4.OSXSAVE is set. The guest's
fpu__init_cpu_xstate only sets CR4.OSXSAVE when xfeatures_mask is non-
zero, and xfeatures_mask is calculated by fpu__init_system_xstate from
CPUID.(EAX=0DH,ECX=0), which doesn't exist on qemu's Westmere
(level=0xb), so XCR0.AVX remains unset and AVX2 instructions #UD.

The bug is probably that raid6_have_avx2 only checks that AVX2 is
supported in CPUID, not that it's enabled. Checking for
X86_FEATURE_OSXSAVE might work, though I'm not sure if the value checked
by boot_cpu_has is stored too early for that.

I am also a little suspicious of kvm_load_guest_xcr0's CR4.OSXSAVE
guard. The Intel manuals state that XSAVE, XSRSTOR, XGETBV and XSETBV
require the flag to be set, but KVM won't restore a guest's existing
XCR0 unless OSXSAVE is still set.

[Kernel-packages] [Bug 1530502] Re: ASUS (UX305CA) Touchpad does not work.

2016-01-05 Thread Greg

UPDATE:  I found email addresses for linux-input, linux-i2c, and I found
one for Dmitry Torokhov but it's a gmail account.  Shouldn't I be
sending this to a kernel.org account??

Ignore my question about html vs. plain text.  I did a google search and
figured it out.

I have not yet booted into the newest (rc8) upstream kernel but will do
so before sending the email.  Can anyone let me know if the gmail
account I found for Dmitry Torokhov is appropriate?

  14e4:1687 broadcom tg3 network driver disconnects under high load

Status in linux package in Ubuntu:
  Triaged

Bug description:
  The tg3 broadcom network driver that binds with chipset 5762 goes
  offline and unable to recover (even with tg3 watchdog timeout) when
  network transmit is under high load.  Then this happens, only a reboot
  would be able to fix it.  Sometimes, however, bringing the interface
  offline and online (via ifconfig) would recover networking.  I've also
  tested with the latest tg3 driver (dec 2014 version) and networking is
  still problematic.I have also disabled TSO, GSO etc... with
  ethtool and the bug still surfaces.  This bug may be related to the
  integrated Firmware.

  Here is the procedure to replicate the issue because it is hard to
  replicate it under moderate network load.

  1. Bootup a machine with a broadcom 5762 NIC (ie. HP DeskElite 705) using a 
Ubuntu/Kubunu Live CD 14.04-15.04.
  2. from another machine: start 5 sessions, repetitively copy (scp with public 
key authentication) a 70 meg file back and forth to the tg3 machine in each 
session. (not sure if this is necessary)
  3. create a 1GB file on the tg3 machine, with something like dd 
if=/dev/urandom of=/my/test/file bs=1024 count=$((1024*1000))
  4. from another machine: repetitively scp copy that 1GB file from the tg3 
machine. This can be done with something like:

  while [ 0 ]; do
     scp -i /my/scp/private.key u...@ip.of.tg3:/my/test/file /tmp
  done;

  Networking will mostly goes offline in about 10-30 minutes.

[Kernel-packages] [Bug 1530502] Re: ASUS (UX305CA) Touchpad does not work.

2016-01-05 Thread Greg

Thank you. I read the instructions but am not entirely clear how to do
so. Am I simply emailing the people mentioned from my own email account
or am I filling out an online form and sending it to them?

Also, I tried to look at the kernel.org directory but could not find an
email for Dimitry Torokhov or linux-input. The instructions were very
in depth about format of my message but was not clear on how I actually
send the message or what the email addresses were.

I also read that the message must be in plain text and not html. I'm
not sure how to tell if my email service is using one or the other and
how to toggle it. Can anyone help me on this?

Lastly, I noticed a new upstream mainline kernel was just posted to the
archive today so I will boot into that first to see if any progress has
been made.

Notice this message under dmesg | grep pnp:
[0.839653] i8042: PNP: PS/2 appears to have AUX port disabled, if this is
incorrect please boot with i8042.nopnp
