Linux 5.6-rc2

Linux 5.6-rc2

[Linus Torvalds]

More than halt the rc2 patch is actually Documentaiton updates,
because the kvm docs got turned into RST.

Another notable chunk is just tooling updates, which is about 50/50
perf updates (much of it due to header file syncing) and - again - kvm
updates.

But if you ignore those parts, and look at only the actual kernel code
updates, things look a bit calmer. The bulk ends up being network
driver updates (intel "ice" driver - E800 series - stands out) with
GPU updates a close second (i915, amd, panfrost). There's a few other
driver updates in there too, but they are mostly hidden in the noise
compared to the network and gpu subsystems: rdma, sound, acpi, block,
gpio etc.

Outside of drivers, there's the usual smattering of changes all over.
Filesystems (nfs, ext4, ceph, cifs, btrfs), architecture updates (x86,
arm), and some core code (scheduling, tracing, networking, io_uring).

The shortlog is appended, you can get a feel for the details by scanning it.

Go forth and test,

               Linus

This didn't happen in rc1, but showed up when I booted into rc2 and
tried to and pull some stuff with rsync.

At a guess (just by functions involved, and the timing between rc1 and
rc2 - no actual analysis), this is probably due to

    28553fa992cb ("Btrfs: fix race between shrinking truncate and fiemap")

which is also marked for stable, so... Filipe?

I assume Filipe wrote this based on my patch here

which makes it so we can allocate safely in this context, but that patch hasn't 
made it's way to you yet.  Do you want it now?  It was prep for a much less safe 
patchset, but is fine by itself.  Thanks,

Josef

I assume it's either that, or revert 28553fa992cb and do it differently..

I'll leave that whole decision to the btrfs people who actually know
the code and the situations and what the alternative would look
like...

I'll send a pull request with fix today. The fixes get cherry-picked
from development branch to current rc branch and sometimes affect each
other. I do test the rc branch independently before sending but I
haven't seen the bug Dave reported.

After rebooting, it didn't reproduce, so it did seem to be dependent on
exactly which files rsync was moving around.  Given it doesn't happen
all the time, little surprise it slipped through I guess.

So what happened was that the patch was developed against the
integration branch, where we don't use search paths in spinning mode
anymore - this was done by Josef's patch, which itself is not a bug fix
but it's necessary for another bug fix that is only on the integration
branch.

On 5.6-rcX and any other other older kernels we have the search using
spinning locks, that's why we run into this problem.

The solution can be either adding Josef's patch or changing the order in
which my patch unlocks the file range - to do it after the patch is
freed (which releases any spin locks it might be holding).

I've just sent a patch for that:
https://patchwork.kernel.org/patch/11386723/

I'm fine with either solution.

Thanks.

So the machine suspends, but never comes back?

Do you need to revert both for it to work for you? Or is the revert of
fdde0ff8590b just to avoid the conflict?

I'm assuming you bisected this, and the bisect indicated e3728b50cd9b,
and then to revert it you reverted the other commit too..

Or what?

fdde0ff85 was just to avoid conflicts.

Lucky guess based on diff rc1..rc2. Bisect was going to be painful, but
could be done if this is not enough clue for Rafael.

Sorry for the delayed response, was away.

I'm guessing that you are using rtcwake for wakeup, in which case reverting
fdde0ff85 alone should unbreak it.

Can you please double check that?

And below is a patch that should fix it if I'm not mistaken (verified on my
system where I was able to reproduce the issue), so it would suffice to test
this one on top of the -rc2.

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Subject: [PATCH] ACPI: PM: s2idle: Check fixed wakeup events in acpi_s2idle_wake()

Commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from
waking up the system") overlooked the fact that fixed events can wake
up the system too and broke RTC wakeup from suspend-to-idle as a
result.

Fix this issue by checking the fixed events in acpi_s2idle_wake() in
addition to checking wakeup GPEs and break out of the suspend-to-idle
loop if the status bits of any enabled fixed events are set then.

Correct on both accounts. Reverting fdde0ff85 alone was enough, and
replacing the reverts with the suggested patch works.

Something from here makes my Toshiba Portege Z30-A (CPU is i5-4210U with 
integrated graphics) to to only get black screen when loading i915 driver.

Happens the same in rc1 and rc2, works OK with all previous kernels.

Re: [Intel-gfx] Linux 5.6-rc2

[Siniša Bandin]

Sorry to bother, but still a "no go" in rc4 (at the same time, 5.5.7 
works OK).

Is there anything else I could do to help fix this?

Here is the dmesg output from my 5.6-rc4:
