* [PATCH] MAINTAINERS: Update remaining @linux.vnet.ibm.com addresses
From: Lukas Bulwahn @ 2019-04-11 4:27 UTC (permalink / raw)

Paul McKenney attempted to update all email addresses @linux.vnet.ibm.com
to @linux.ibm.com in commit 1dfddcdb95c4
("MAINTAINERS: Update from @linux.vnet.ibm.com to @linux.ibm.com"), but
some still remained.
We update the remaining email addresses in MAINTAINERS, hopefully finally
catching all cases for good.
Fixes: 1dfddcdb95c4 ("MAINTAINERS: Update from @linux.vnet.ibm.com to @linux.ibm.com")

I think I asked that on an earlier iteration, and the answer is no.
The names are confusing, but this file is all about xics-on-xive
rather than xive native. So here we're checking what's available from
the guest's point of view, so "xics", but most of the surrounding
functions are named "xive" because that's the backend.

atomic64_read() returns "long" which matches "%ld", why this change (and
similar below)? You did not do this in the two pr_debug()s above anyway.

Yes, that would be much nicer. I'll probably do something like that in

* [PATCH V3] powernv: sensor-groups: Add debugfs file to enable/disable sensor groups
From: Shilpasri G Bhat @ 2019-04-11 3:54 UTC (permalink / raw)
To: mpe; +Cc: ego, linuxppc-dev, linux-kernel, Shilpasri G Bhat
This patch provides support to disable and enable platform specific
sensor groups like performance, utilization and frequency which are
not supported in hwmon.
Signed-off-by: Shilpasri G Bhat <shilpa.bhat@linux.vnet.ibm.com>
---
Changes from V2:
- Rebase on master
Changes from V1:
- As per Michael Ellerman's suggestion, adding the "enable" files to debugfs.
The original code had been written in mind to accomodate the "enable" file
in the same path as "clear" attribute. As this is not required anymore
the code is cleaned up to bifurcate the functions adding "enable" and
"clear" attribute.

You should preserve the changelog of what has changed in each version, not only
the last changes, so that there is a logical flow and the maintainers do not
have to dig up previous versions:
Changes in v3:
- Update subject line.
Changes in v2:
- Fix "Fixes" tag.
Also, for this type of fixes, make sure to always Cc lkml: linux-kernel@vger.kernel.org

* [PATCH v2 5/5] nohz_full: Allow the boot CPU to be nohz_full
From: Nicholas Piggin @ 2019-04-11 3:34 UTC (permalink / raw)
To: Thomas Gleixner, Frederic Weisbecker
Cc: linux-arch, Peter Zijlstra, Rafael J . Wysocki, linux-kernel,

In-Reply-To: <20190411033448.20842-1-npiggin@gmail.com>
Allow the boot CPU / CPU0 to be nohz_full. Have the boot CPU take the
do_timer duty during boot until a housekeeping CPU can take over.
This is supported when CONFIG_PM_SLEEP_SMP is not configured, or when
it is configured and the arch allows suspend on non-zero CPUs.
nohz_full has been trialed at a large supercomputer site and found to
significantly reduce jitter. In order to deploy it in production, they
need CPU0 to be nohz_full because their job control system requires
the application CPUs to start from 0, and the housekeeping CPUs are
placed higher. An equivalent job scheduling that uses CPU0 for
housekeeping could be achieved by modifying their system, but it is
preferable if nohz_full can support their environment without
modification.

During housekeeping mask setup, currently a possible CPU is required.
That does not guarantee the CPU would be available at boot time, so
check to ensure that at least one present CPU is in the mask.

* [PATCH v2 3/5] kernel/cpu: Allow non-zero CPU to be primary for suspend / kexec freeze
From: Nicholas Piggin @ 2019-04-11 3:34 UTC (permalink / raw)
To: Thomas Gleixner, Frederic Weisbecker
Cc: linux-arch, Peter Zijlstra, Rafael J . Wysocki, linux-kernel,

In-Reply-To: <20190411033448.20842-1-npiggin@gmail.com>
This patch provides an arch option, ARCH_SUSPEND_NONZERO_CPU, to
opt-in to allowing suspend to occur on one of the housekeeping CPUs
rather than hardcoded CPU0.
This will allow CPU0 to be a nohz_full CPU with a later change.
It may be possible for platforms with hardware/firmware restrictions
on suspend/wake effectively support this by handing off the final
stage to CPU0 when kernel housekeeping is no longer required. Another
option is to make housekeeping / nohz_full mask dynamic at runtime,
but the complexity could not be justified at this time.

* [PATCH v2 2/5] PM / suspend: add function to disable secondaries for suspend

This adds a function to disable secondary CPUs for suspend that are
not necessarily non-zero / non-boot CPUs. Platforms will be able to
use this to suspend using non-zero CPUs.

This has no effect yet because CPU0 will always be a housekeeping CPU

* [PATCH v2 0/5] Allow CPU0 to be nohz full
From: Nicholas Piggin @ 2019-04-11 3:34 UTC (permalink / raw)
To: Thomas Gleixner, Frederic Weisbecker
Cc: linux-arch, Peter Zijlstra, Rafael J . Wysocki, linux-kernel,

Since last time, I added a compile time option to opt-out of this
if the platform does not support suspend on non-zero, and tried to
improve legibility of changelogs and explain the justification
better.
I have been testing this on powerpc/pseries and it seems to work
fine (the firmware call to suspend can be called on any CPU and
resumes where it left off), but not included here because the
code has some bitrot unrelated to this series which I hacked to
fix. I will discuss it and either send an acked patch to go with
this series if it is small, or fix it in powerpc tree.
Thanks,
Nick

I believe the release operation is not called until all of the mmaps
using the fd are unmapped - which is a good thing for us, since it
means the guest can't possibly be accessing the XIVE directly.
You might want to reword that last paragraph to mention that.

Should that be kvmppc_xive_enabled() rather than xics?

I see mm_init() is called before lockup_detector_init(); both from start_kernel().
Thus, IMHO, kzalloc should work at this point.

* Re: [PATCH] Linux: Define struct termios2 in <termios.h> under _GNU_SOURCE [BZ #10339]

I still think the better strategy, from both BZ#10339 and recent thread
discussion about the issue on libc-alpha, is rather to:
1. Start to use termios2 ioctl kabi instead of termios1. The only
missing spot is alpha pre linux 4.20.
2. Adjust sparc and mips to add c_ispeed and c_ospeed along with
compat symbols to use termios1. This will allow also some cleanup
to remove _HAVE_STRUCT_TERMIOS_C_{O,I}SPEED.
3. Use the compat symbols for alpha pre-4.20.
4. With termios Linux ABI being essentially the same for all supported
architectures (with support for c_ospeed and c_ispeed) we can move
forward to adapt the current cfgetospeed, cfgetispeed, cfsetospeed,
cfsetispeed to work with arbitrary values.
The POSIX and Linux extended BXX values will need to be handled
exceptionally. It means their integers values will be reserved and
mapped to the termios2 values. The code resulting code for cfsetospeed,
for instance, would be:
---
static inline speed_t
c_ispeed (tcflag_t c_cflag)
{
return (c_cflag >> IBSHIFT) & CBAUD;
}
/*
* The top four bits in speed_t are reserved for future use, and *currently*
* the equivalent values are the only valid baud_t values.
*/
static inline bool
invalid_speed (speed_t x)
{
return x > 0x0fffffff;
}
/* Set the output baud rate stored in *TERMIOS_P to the symbol SPEED */
int
cfsetospeed (struct termios *termios_p, speed_t speed)
{
if (invalid_speed (speed))
{
__set_errno (EINVAL);
return -1;
}
termios_p->c_ospeed = speed_kernel_from_user (speed);
if ( c_ispeed (termios_p->c_cflag) == B0 )
termios_p->c_ispeed = termios_p->c_ospeed;
if ( (speed & ~CBAUD) != 0 || speed > _MAX_BAUD )
speed = BOTHER;
/*
* Don't set the input flags here; the B0 in c_cflag indicates that
* the input speed is tied to the output speed.
*/
termios_p->c_cflag = (termios_p->c_cflag & ~CBAUD) | speed;
return 0;
}
---
This allows us to adjust the baud rates to non-standard values using termios
interfaces without to resorting to add new headers and use a different API
(ioctl).
As Peter Anvin has indicated, he create a POC [1] with the aforementioned
new interfaces. It has not been rebased against master, more specially against
my termios refactor to simplify the multiple architecture header definitions,
but I intend to use as a base.
