Subject: [PATCH 06/44] meson: move build files to repository root
Per the README and github ticket discussion, the purpose of having it in
contrib/ is to gauge community interest. This interest has now been
expressed by several parties, so that interest is certainly there.
Let's move it to a more discoverable location. This has two benefits:
- usability. If various parties intend to use it, then it is easier to
do so from the repository root rather than cd'ing into a subdir.
- discoverability. At least Gentoo didn't initially realize it existed,
since it wasn't in the repository root, but switched after realizing.
It seems reasonable that other redistributors, too, would be
interested in evaluating its use but hadn't previously noticed the
option.

Subject: [PATCH 08/44] meson: drop redundant install_man() options
It is unnecessary to set the install directory for manpages, since meson
infers this from the file extension and installs *.1 manpages to mandir
in the man1 section for you.
It is also unnecessary to tag them as "en" because that is the
default... it is likewise unnecessary to tag them with manual file
permissions since the default 644 permission is also the overridden one.

Subject: [PATCH 09/44] meson: add a minimum version decorator
Indicate the minimum required version of meson. Version 0.47 (released
March 2020) is needed regardless, since it provides the cross-platform
curses dependency wrapper. This just lets meson know that, so it
can:
- warn you if you use features from newer versions you didn't intend to
use, which is a sign to either require a higher minimum or avoid the
new feature for maximal compatibility
- error out if you have an older version of meson too old to build
correctly with

Subject: [PATCH 22/44] Wrap migrate_irq in a higher level utility function
Add migrate_irq_obj and replace existing migrate_irq calls with calls to
the new function. migrate_irq_obj takes source and destination
topo_obj's instead of interrupt lists so as to factor out updating of
the load on the destination cpu and of info->asssigned_obj.
Pass NULL as destination to move irq to rebalance_irq_list.
Drop the unneeded force_irq_migration.

Subject: [PATCH 23/44] Track IRQ "slots" count per CPU to avoid overflowing
There are situations where irqbalance may try to migrate large numbers of
IRQs to a topo_obj, there's no upper bound on the number as the
placement logic is based on load mainly. The kernel's irq bitmasks limit
the number of IRQs on each cpu and if more are tried to be migrated, the
write to smp_affinity returns -ENOSPC. This confuses irqbalance's
logic, the topo_obj.interrupts list no longer matches the irqs actually
on that CPU or cache domain, and results in floods of error messages.
See https://github.com/Irqbalance/irqbalance/issues/303 for details.
For an easy fix, track the number of IRQ slots still free on each CPU.
We start with INT_MAX meaning "unknown" and when we first get a -ENOSPC,
we know we have no slots left. From there update the slots count each
time we migrate IRQs to/from the CPU core topo_obj. We may never see an
-ENOSPC and in that case there's no change in current logic, we never
start tracking.
This way we don't need to know ahead of time how many slots the kernel
has for each CPU. The number may be arch specific (it is about 200 on
x86-64) and is dependent on the number managed IRQs kernel has
registered, so we don't want to guess. This is also more tolerant to
the topo_obj.interrupts lists not matching exactly the kernel's idea of
each irq's current affinity, e.g. due to -EIO errors in the smp_affinity
writes.
For now only do the tracking at OBJ_TYPE_CPU level so we don't have to
update slots_left for all parent objs.
Th commit doesn't try to stop an ongoing activation of all the IRQs
already scheduled for moving to one cpu, when that cpu starts returning
ENOSPC. We'll still see a bunch of those errors in that iteration.
But in subsequent calculate_placement() iterations we avoid assigning
more IRQs to that cpu than we were able to successfully move before.

Subject: [PATCH 40/44] Version option should return 0 rather than 1
Previously invoke irqbalance with --version options, the return value
is 1 instead of 0:
$ irqbalance --version
irqbalance version 1.9.4
$ echo $?
1
It is unexpected because irqbalance have successfully returned the
version string with no errors, so 0 should be returned instead of 1.
This will confuse some automation tests.
This patch will make irqbalance return the correct value for version
option.

Subject: [PATCH 41/44] Add CAP_SETPCAP to CapabilityBoundingSet in
irqbalance.service
A error message of 'libcap-ng used by "/usr/sbin/irqbalance" failed dropping
bounding set due to not having CAP_SETPCAP in capng_apply' is noticed.
Previously a similar issue[1] has been fixed by the following commit:
efab272 Drop CapabilityBoundingSet from irqbalance service
43751df drop NoNewPrivs from irqbalance service
in which, CapabilityBoundingSet and NoNewPrivs parameters are dropped
from the irqbalance.service, and get restored by the following commit
later:
a99b604 Set additional systemd options for service
So this patch will not do the dropping again, but add CAP_SETPCAP to
CapabilityBoundingSet instead.

Subject: [PATCH 44/44] Use EPERM instead of EIO when try setting irq affinity
fails
Kernel commit eb29369fa543e ("genirq/proc: Change the return value for
set affinity permission error") changed the error number from EIO to
EPERM when a specific irq failed to set affinity from userspace.
In addition, users have complained about EIO is misleading when
setting affinity fails, however it just meaning "user cannot set
affinity", so EPERM is better for that.
This patch will follow the kernel change, to unify the behaviour of
irqbalance from the kernels which have not integrated the kernel
commit mentioned above.
