- Parallel CPU bringup
The reason why people are interested in parallel bringup is to shorten
the (kexec) reboot time of cloud servers to reduce the downtime of the
VM tenants.
The current fully serialized bringup does the following per AP:
1) Prepare callbacks (allocate, intialize, create threads)
2) Kick the AP alive (e.g. INIT/SIPI on x86)
3) Wait for the AP to report alive state
4) Let the AP continue through the atomic bringup
5) Let the AP run the threaded bringup to full online state
There are two significant delays:
#3 The time for an AP to report alive state in start_secondary() on
x86 has been measured in the range between 350us and 3.5ms
depending on vendor and CPU type, BIOS microcode size etc.
#4 The atomic bringup does the microcode update. This has been
measured to take up to ~8ms on the primary threads depending on
the microcode patch size to apply.
On a two socket SKL server with 56 cores (112 threads) the boot CPU
spends on current mainline about 800ms busy waiting for the APs to come
up and apply microcode. That's more than 80% of the actual onlining
procedure.
This can be reduced significantly by splitting the bringup mechanism
into two parts:
1) Run the prepare callbacks and kick the AP alive for each AP which
needs to be brought up.
The APs wake up, do their firmware initialization and run the low
level kernel startup code including microcode loading in parallel
up to the first synchronization point. (#1 and #2 above)
2) Run the rest of the bringup code strictly serialized per CPU
(#3 - #5 above) as it's done today.
Parallelizing that stage of the CPU bringup might be possible in
theory, but it's questionable whether required surgery would be
justified for a pretty small gain.
If the system is large enough the first AP is already waiting at the
first synchronization point when the boot CPU finished the wake-up of
the last AP. That reduces the AP bringup time on that SKL from ~800ms
to ~80ms, i.e. by a factor ~10x.
The actual gain varies wildly depending on the system, CPU, microcode
patch size and other factors. There are some opportunities to reduce
the overhead further, but that needs some deep surgery in the x86 CPU
bringup code.
For now this is only enabled on x86, but the core functionality
obviously works for all SMP capable architectures.
- Enhancements for SMP function call tracing so it is possible to locate
the scheduling and the actual execution points. That allows to measure
IPI delivery time precisely.

above)
2) Run the rest of the bringup code strictly serialized per CPU
(#3 - #5 above) as it's done today.
Parallelizing that stage of the CPU bringup might be possible
in theory, but it's questionable whether required surgery
would be justified for a pretty small gain.
If the system is large enough the first AP is already waiting at
the first synchronization point when the boot CPU finished the
wake-up of the last AP. That reduces the AP bringup time on that
SKL from ~800ms to ~80ms, i.e. by a factor ~10x.
The actual gain varies wildly depending on the system, CPU,
microcode patch size and other factors. There are some
opportunities to reduce the overhead further, but that needs some
deep surgery in the x86 CPU bringup code.
For now this is only enabled on x86, but the core functionality
obviously works for all SMP capable architectures.
- Enhancements for SMP function call tracing so it is possible to
locate the scheduling and the actual execution points. That allows
to measure IPI delivery time precisely"

. Add auto cleanup of user events
Have the user events automatically get removed when the last
reference (file descriptor) is closed. This was asked for to
prevent leaks of user events hanging around needing admins
to clean them up.
. Add persistent logic (but not let user space use it yet)
In some cases, having a persistent user event (one that does not
get cleaned up automatically) is useful. But there's still
debates about how to expose this to user space. The infrastructure
is added, but the API is not.

There have not been a lot of fixes for for the soc tree in 6.4, but
these have been sitting here for too long.
For the devicetree side, there is one minor warning fix for vexpress,
the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
for the iMX8 clocks and its USB-3.0 gadget device, as well as board
specific fixes for regulators and the phy on some of the i.MX boards.
The microchip risc-v and arm32 maintainers now also add a shared
maintainer file entry for the arm64 parts.
The remaining fixes are all for firmware drivers, addressing mistakes in
the optee, scmi and ff-a firmware driver implementation, mostly in the
error handling code, incorrect use of the alloc_workqueue() interface in
SCMI, and compatibility with corner cases of the firmware implementation.

Pull vfs fixes from Christian Brauner:
- During the acl rework we merged this cycle the generic_listxattr()
helper had to be modified in a way that in principle it would allow
for POSIX ACLs to be reported. At least that was the impression we
had initially. Because before the acl rework POSIX ACLs would be
reported if the filesystem did have POSIX ACL xattr handlers in
sb->s_xattr. That logic changed and now we can simply check whether
the superblock has SB_POSIXACL set and if the inode has
inode->i_{default_}acl set report the appropriate POSIX ACL name.
However, we didn't realize that generic_listxattr() was only ever
used by two filesystems. Both of them don't support POSIX ACLs via
sb->s_xattr handlers and so never reported POSIX ACLs via
generic_listxattr() even if they raised SB_POSIXACL and did contain
inodes which had acls set. The example here is nfs4.
As a result, generic_listxattr() suddenly started reporting POSIX
ACLs when it wouldn't have before. Since SB_POSIXACL implies that the
umask isn't stripped in the VFS nfs4 can't just drop SB_POSIXACL from
the superblock as it would also alter umask handling for them.
So just have generic_listxattr() not report POSIX ACLs as it never
did anyway. It's documented as such.
- Our SB_* flags currently use a signed integer and we shift the last
bit causing UBSAN to complain about undefined behavior. Switch to
using unsigned. While the original patch used an explicit unsigned
bitshift it's now pretty common to rely on the BIT() macro in a lot
of headers nowadays. So the patch has been adjusted to use that.
- Add Namjae as ntfs reviewer. They're already active this cycle so
let's make it explicit right now.

Krzysztof noticed that patches for arch/arm64/boot/dts/microchip were
getting lost & the listed tree was inactive.
Nicolas and I are willing to shepherd patches to Arnd, using the
existing at91 tree, so add a new entry covering
arch/arm64/boot/dts/microchip, listing us as maintainers.
Drop the tree from the existing sparx5 entry & narrow the devicetree
pattern to just sparx devices, leaving Lars, Steen and Daniel looking
after support for their SoCs.

It's hard to keep track of changes to the process docs.
Subsystem maintainers should probably know what's going on,
to ensure reasonably uniform developer experience across
trees.
We also need a place where process discussions can be held
(i.e. designated mailing list which can be CCed on naturally
arising discussions). I'm using workflows@ in this RFC,
but a new list may be better.
No change to the patch flow intended.
