[Ubuntu Kernel Bot]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
focal' to 'verification-done-focal'. If the problem still exists, change
the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Hsuan-Yu Lin]

Discussion minutes from IRC #hwe (2020/06/12):
 
 15:37:35  khfeng: so, should the e1000e commits be rejected, 
according to your comment on the bug?
 15:39:18  tjaalton, depends on kentlin_office. If we care about the 
power consumption under s0ix, then probably should reject it
 15:40:02  ok, I'll drop it from the list for now
 15:40:27  tjaalton, khfeng, what commit
 15:41:05  kentlin_office, the one the prevents vPro systems from 
entering s0ix
 15:42:10  khfeng, oh.. we care about S0ix...
 15:42:43  khfeng, the patch is submitted by whom?
 15:44:52  kentlin_office, dunno
 15:45:02 <-- chih (c...@1-34-63-143.hinet-ip.hinet.net) has quit (Ping

 15:45:29  khfeng, from upstream?
 15:45:31 --> chih (c...@61-220-137-34.hinet-ip.hinet.net) has joined #hwe
 15:45:55  kentlin_office, yea
 15:45:59  intel
 15:47:05  tjaalton, in latest Kernel? do you have but or git 
cold share with me? I want to write email to Intel contact why they send such 
commit...
 15:50:38  shane: ^
 15:55:04  kentlin_office: it's in linus's git tree now
 15:55:11  tjaalton: got it, have talked with kentlin_office
 15:55:51  what's the verdict?
 15:56:02  should I drop both

 16:08:06  khfeng: I can't find your e1000e commit in the trees where 
it was supposed to be applied already.. do you know what happened?
 16:08:19  not in focal at least
 16:09:28  tjaalton, "e1000e: Disable TSO for buffer overrun 
workaround" this one?
 16:09:34  yes
 16:11:38 --> ethanhsieh_home (et...@1-171-165-81.dynamic-ip.hinet.net) has 
joined #hwe
 16:13:00  perhaps I should ask the ones who applied it
 16:14:39  it's in bionic at least
 16:14:46  but not focal. probably a mistake
 16:14:54  khfeng: so, nevermind :)
 16:15:12  Ok :)
 16:15:30 <-- ethanhsieh_home (et...@1-171-165-81.dynamic-ip.hinet.net) has 
quit (Quit: Leaving)
 16:20:42 <-> alextu is now known as alextu-meeting
 16:25:43  vicamo: so, back to iommu.. I'm not really sure :D
 16:26:12  tjaalton: I saw you're merging "NAK: [PATCH 
0/2][SRU][B/E/F/U/OEM-OSP1-B/OEM-5.6] PCI: Avoid FLR for AMD Matisse/Starship 
HD Audio & USB 3.0"?

 16:27:30  vicamo: oh, that was a mistake.. already replied to the 
correct thread
 16:27:54  khfeng: are you interested in that power button issue? are 
holding a conf call
 16:28:04  vicamo, sure
 16:28:06  tjaalton: ok, thanks
 16:28:59 <-- hugh_chao (hughc...@61-220-137-37.hinet-ip.hinet.net) has quit 
(Ping timeout: 121 seconds)
 16:31:39  khfeng: forwarded conf info for you
 16:32:00  shane: so what should I do with those patches?
 16:37:18  vicamo, joined via phonecall?
 16:37:21  tjaalton: sorry, wait a minute
 16:37:39  khfeng: yes
 16:43:40  tjaalton: Do you mean 
https://lists.ubuntu.com/archives/kernel-team/2020-June/110994.html ?
 16:47:15  kentlin_office, vicamo, ... what was that
 16:47:24  kentlin_office, purely wasting time
 16:47:30  shane: yes
 16:50:11  shane: I applied before reading the bug comment
 16:51:14  tjaalton: the commits are from here 
https://bugs.launchpad.net/somerville/+bug/1872029
 16:51:14  Bug #1872029: [Task] e1000e S0ix support for TGL  

 

 16:53:34  I know it's in upstream 5.8 tree
 16:54:11  both of these
 16:54:48  tjaalton: you want them to be cherry picked from master tree?
 16:55:31  AceLan: no, khfeng said the second patch causes issues
 16:58:18  shane: what did you decide after discussing with 
kentlin_office?
 16:59:21  tjaalton: kentlin_office says he will ask AceLan..
 16:59:52 <-- kyleN (knitzs...@c-73-123-35-110.hsd1.ma.comcast.net) has quit

 17:01:27  humm
 17:02:00  haha
 17:02:34 --> kyleN (knitzs...@c-73-123-35-110.hsd1.ma.comcast.net) has joined 
#hwe
 17:02:44  and should I just apply that iommu patchset? guess we'll 
find out soon enough it the world blows up..
 17:03:20  khfeng: ^^ # from the e1000e commit description it says 
"Since ME systems do not support SLP_S0 in S0ix state, and S0ix entry and exit 
flows may cause errors on them" do you still think we shouldn't apply this 
commit?
 17:04:11  AceLan, so we need this patch to enter SLP_S0?
 17:04:26  AceLan, depends on if we want the systems reach s0ix
 17:04:30  AceLan, base on what commit say?
 17:04:38  kentlin_office, the patch _prevents_ s0ix
 17:04:55  kentlin_office: 
https://lists.ubuntu.com/archives/kernel-team/2020-June/110805.html
 17:06:54  AceLan, khfeng so only e1000e could not enter s0ix 
with this patch.. is that what it meant or the whole system?
 17:07:45  kentlin_office, ??
 17:08:32  kentlin_office: only the prevent the listed nic i217, i218, 
and i219 from entering s0ix
 17:10:40  kentlin_office, s0ix is an SoC state...

Do note that "e1000e: disable s0ix entry and exit flows for ME systems"
actually prevents most business laptops from reaching SLP_S0.
