  Dear maintainer, please cherry-pick the fix alreayd available upstream 
containing the additional check to avoid the issue here described. It must 
apply cleanly on stable kernels:

  "powerpc/tm: Flush TM only if CPU has TM feature":
  
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c1fa0768a8713b135848f78fd43ffc208d8ded70

  Please cherry-pick the pointed out fix and apply it to kernel:

  HWE 4.x
  HWE 4.13

  HWE-edge 4.15 already has the fix in place.

[Kernel-packages] [Bug 1763685] Re: Fix for flushing TM on coredump only if CPU has TM feature

2018-06-15 Thread Joseph Salisbury

Now that I review this again, I don't think commit 
c1fa0768a8713b135848f78fd43ffc208d8ded70 is needed in Xenial proper, since it 
is 4.4 based.  Commit c1fa0768a871 fixes the following commit:
cd63f3c ("powerpc/tm: Fix saving of TM SPRs in core dump")

However, commit cd63f3c was not added to mainline until v4.13-rc4.

Can you confirm this?  If commit c1fa0768a871 is not needed in Xenial,
there is nothing to test and this bug should be resolved since it's
specific to Artful and Xenial HWE kerenl(4.13 based).

  Fix for flushing TM on coredump only if CPU has TM feature

  ---Additional Hardware Info---
  POWER9/POWER8/compat mode 
   
  Machine Type = P9 baremetal + VM (POWER9, POWER8, Compat mode) 
   
  ---Steps to Reproduce---
   On POWER9 machines it's possible that TM is disabled for use by the VMs and 
if a coredump is generated in the VM it will crash since it will execute TM 
instructions when coredumping if a check is not present on the VM's kernel. 
Since POWER9 can run VM on P8 compatibility mode, it's necessary to patch all 
kernels that run on compat mode as well.

[Kernel-packages] [Bug 1763685] Re: Fix for flushing TM on coredump only if CPU has TM feature

2018-04-23 Thread Joseph Salisbury

The last day for the current SRU cycle was on April 20th, which will
release to updates on May 14th.

The last day for kernel commits for the next cycle in May 11th, which
will release on June 4th, so there should be plenty of time for testing.

  Fix for flushing TM on coredump only if CPU has TM feature

  ---Additional Hardware Info---
  POWER9/POWER8/compat mode 
   
  Machine Type = P9 baremetal + VM (POWER9, POWER8, Compat mode) 
   
  ---Steps to Reproduce---
   On POWER9 machines it's possible that TM is disabled for use by the VMs and 
if a coredump is generated in the VM it will crash since it will execute TM 
instructions when coredumping if a check is not present on the VM's kernel. 
Since POWER9 can run VM on P8 compatibility mode, it's necessary to patch all 
kernels that run on compat mode as well.

[Kernel-packages] [Bug 1763685] Re: Fix for flushing TM on coredump only if CPU has TM feature

2018-04-16 Thread Joseph Salisbury

Commit c1fa0768a8713b135848f78fd43ffc208d8ded70 is already in Artful as
of version: Ubuntu-4.13.0-17.20.  It came in with the 4.13.5 upstream
stable updates.

Commit c1fa0768a8713b135848f78fd43ffc208d8ded70 is not in upstream
stable v4.4.y.   This is probably because the commit needs a back port
for v4.4.  I performed a back port to the Xenial 4.4 kernel and built a
test kernel with it.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1763685

Can you test this kernel and see if it resolves this bug?

Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb packages.

Thanks in advance!

  Fix for flushing TM on coredump only if CPU has TM feature

  ---Additional Hardware Info---
  POWER9/POWER8/compat mode 
   
  Machine Type = P9 baremetal + VM (POWER9, POWER8, Compat mode) 
   
  ---Steps to Reproduce---
   On POWER9 machines it's possible that TM is disabled for use by the VMs and 
if a coredump is generated in the VM it will crash since it will execute TM 
instructions when coredumping if a check is not present on the VM's kernel. 
Since POWER9 can run VM on P8 compatibility mode, it's necessary to patch all 
kernels that run on compat mode as well.

  Dear maintainer, please cherry-pick the fix alreayd available upstream 
containing the additional check to avoid the issue here described. It must 
apply cleanly on stable kernels:

  "powerpc/tm: Flush TM only if CPU has TM feature":
  
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c1fa0768a8713b135848f78fd43ffc208d8ded70

  Please cherry-pick the pointed out fix and apply it to kernel:

  HWE 4.x
  HWE 4.13

  HWE-edge 4.15 already has the fix in place.
