Dmitrii, Fangrui, and Mashahiro note:
Before GCC 11 and Clang 12 -gsplit-dwarf implicitly uses -g2.
Fix CONFIG_DEBUG_INFO_SPLIT for gcc-11+ & clang-12+ which now need -g
specified in order for -gsplit-dwarf to work at all.
-gsplit-dwarf has been mutually exclusive with -g since support for
CONFIG_DEBUG_INFO_SPLIT was introduced in
commit 866ced950b ("kbuild: Support split debug info v4")
I don't think it ever needed to be.

====================
A small patch set adding few usability improvements and features making
veristat a more convenient tool to be used for work on BPF verifier:
- patch #2 speeds up and makes stats parsing from BPF verifier log more
robust;
- patch #3 makes veristat less strict about input object files; veristat
will ignore non-BPF ELF files;
- patch #4 adds progress log, by default, so that user doing
mass-verification is aware that veristat is not stuck;
- patch #5 allows to tune requested BPF verifier log level, which makes
veristat a simplest way to get BPF verifier log, especially successfully
verified ones.
v1->v2:
- don't emit progress in non-table mode, as it breaks CSV output.

Add -l (--log-level) flag to override default BPF verifier log lever.
This only matters in verbose mode, which is the mode in which veristat
emits verifier log for each processed BPF program.
This is important because for successfully verified BPF programs
log_level 1 is empty, as BPF verifier truncates all the successfully
verified paths. So -l2 is the only way to actually get BPF verifier log
in practice. It looks sometihng like this:
[vmuser@archvm bpf]$ sudo ./veristat xdp_tx.bpf.o -vl2

Emit "Processing <filepath>..." for each BPF object file to be
processed, to show progress. But also add -q (--quiet) flag to silence
such messages. Doing something more clever (like overwriting same output
line) is to cumbersome and easily breakable if there is any other
console output (e.g., errors from libbpf).

Make veristat ignore non-BPF object files. This allows simpler
mass-verification (e.g., `sudo ./veristat *.bpf.o` in selftests/bpf
directory). Note that `sudo ./veristat *.o` would also work, but with
selftests's multiple copies of BPF object files (.bpf.o and
.bpf.linked{1,2,3}.o) it's 4x slower.
Also, given some of BPF object files could be incomplete in the sense
that they are meant to be statically linked into final BPF object file
(like linked_maps, linked_funcs, linked_vars), note such instances in
stderr, but proceed anyways. This seems like a better trade off between
completely silently ignoring BPF object file and aborting
mass-verification altogether.

Make sure veristat doesn't spend ridiculous amount of time parsing
verifier stats from verifier log, especially for very large logs or
truncated logs (e.g., when verifier returns -ENOSPC due to too small
buffer). For this, parse lines from the end of the log and make sure we
parse only up to 100 last lines, where stats should be, if at all.

START_USER_RECOVERY and END_USER_RECOVERY are two new control commands
to support user recovery feature.
After a crash, user should send START_USER_RECOVERY, it will:
(1) check if (a)current ublk_device is UBLK_S_DEV_QUIESCED which was
set by quiesce_work and (b)chardev is released
(2) reinit all ubqs, including:
(a) put the task_struct and reset ->ubq_daemon to NULL.
(b) reset all ublk_io.
(3) reset ub->mm to NULL.
Then, user should start a new process and send FETCH_REQ on each
ubq_daemon.
Finally, user should send END_USER_RECOVERY, it will:
(1) wait for all new ubq_daemons getting ready.
(2) update ublksrv_pid
(3) unquiesce the request queue and expect incoming ublk_queue_rq()
(4) convert ub's state to UBLK_S_DEV_LIVE
Note: we can handle STOP_DEV between START_USER_RECOVERY and
END_USER_RECOVERY. This is helpful to users who cannot start new process
after sending START_USER_RECOVERY ctrl-cmd.

With USER_RECOVERY feature enabled, the monitor_work schedules
quiesce_work after finding a dying ubq_daemon. The monitor_work
should also abort all rqs issued to userspace before the ubq_daemon is
dying. The quiesce_work's job is to:
(1) quiesce request queue.
(2) check if there is any INFLIGHT rq. If so, we retry until all these
rqs are requeued and become IDLE. These rqs should be requeued by
ublk_queue_rq(), task work, io_uring fallback wq or monitor_work.
(3) complete all ioucmds by calling io_uring_cmd_done(). We are safe to
do so because no ioucmd can be referenced now.
(5) set ub's state to UBLK_S_DEV_QUIESCED, which means we are ready for
recovery. This state is exposed to userspace by GET_DEV_INFO.
The driver can always handle STOP_DEV and cleanup everything no matter
ub's state is LIVE or QUIESCED. After ub's state is UBLK_S_DEV_QUIESCED,
user can recover with new process.
Note: we do not change the default behavior with reocvery feature
disabled. monitor_work still schedules stop_work and abort inflight
rqs. And finally ublk_device is released.

io_uring caches task references to avoid doing atomics for each of them
per request. If a request is put from the same task that allocated it,
then we can maintain a per-ctx cache of them. This obviously relies
on io_uring always pruning caches in a reliable way, and there's
currently a case off io_uring fd release where we can miss that.
One example is a ring setup with IOPOLL, which relies on the task
polling for completions, which will free them. However, if such a task
submits a request and then exits or closes the ring without reaping
the completion, then ring release will reap and put. If release happens
from that very same task, the completed request task refs will get
put back into the cache pool. This is problematic, as we're now beyond
the point of pruning caches.
Manually drop these caches after doing an IOPOLL reap. This releases
references from the current task, which is enough. If another task
happens to be doing the release, then the caching will not be
triggered and there's no issue.

by "A + step %4" and number to "A + step /4" i.e, GMD step
0 maps to STEP_A0, 1 to _A1, 2 to _A2, 3 to _A3, 4 to STEP_B0...
Future platforms might break this formulae and may require a table

When attach_prog_fd field was removed in libbpf 1.0 and replaced with
`long: 0` placeholder, it actually shifted all the subsequent fields by
8 byte. This is due to `long: 0` promising to adjust next field's offset
to long-aligned offset. But in this case we were already long-aligned
as pin_root_path is a pointer. So `long: 0` had no effect, and thus
didn't feel the gap created by removed attach_prog_fd.
Non-zero bitfield should have been used instead. I validated using
pahole. Originally kconfig field was at offset 40. With `long: 0` it's
at offset 32, which is wrong. With this change it's back at offset 40.
While technically libbpf 1.0 is allowed to break backwards
compatibility and applications should have been recompiled against
libbpf 1.0 headers, but given how trivial it is to preserve memory
layout, let's fix this.

Old, circa 2002 chipsets have a bug: they don't go idle when they are
supposed to. So, a workaround was added to slow the CPU down and
ensure that the CPU waits a bit for the chipset to actually go idle.
This workaround is ancient and has been in place in some form since
the original kernel ACPI implementation.
But, this workaround is very painful on modern systems. The "inl()"
can take thousands of cycles (see Link: for some more detailed
numbers and some fun kernel archaeology).
First and foremost, modern systems should not be using this code.
Typical Intel systems have not used it in over a decade because it is
horribly inferior to MWAIT-based idle.
Despite this, people do seem to be tripping over this workaround on
AMD system today.
Limit the "dummy wait" workaround to Intel systems. Keep Modern AMD
systems from tripping over the workaround. Remotely modern Intel
systems use intel_idle instead of this code and will, in practice,
remain unaffected by the dummy wait.

The cgroup_hierarchical_stats selftest is complicated. It has to be,
because it tests an entire workflow of recording, aggregating, and
dumping cgroup stats. However, some of the complexity is unnecessary.
The test now enables the memory controller in a cgroup hierarchy, invokes
reclaim, measure reclaim time, THEN uses that reclaim time to test the
stats collection and aggregation. We don't need to use such a
complicated stat, as the context in which the stat is collected is
orthogonal.
Simplify the test by using a simple stat instead of reclaim time, the
total number of times a process has ever entered a cgroup. This makes
the test simpler and removes the dependency on the memory controller and
the memory reclaim interface.

status - there's no need for rmi_f34v7_start_reflash() to do the same just
before calling rmi_f34v7_enter_flash_prog().

All register offsets are fixed, and a number of places even read or
write multiple registers as a block, so there is no way to support
reordering them without move involved changes. Remove the unneeded level
of indirection in the register access.

A full erase is required to recover from error conditions like "Bad
Partition Table". Various individual partition erase commands can be
(and need to be) omitted, as they will fail until a new partition table
has been written.

When recovering from a bad partition table (for example after an
interrupted update), a reset is necessary for the new partition table to
become effective. Without this reset, writing the core code partition
will fail with status 0x03 (Invalid Command).

Preparation for use of the "erase application" command, which is required
to recover from a bad partition table error condition. Rather than adding
complex fallback error paths for such errors, it seems more robust to do
the full erase unconditionally.

The command register is reset to 0 when a command has completed. Check
for this condition instead of the error status, which will not accurately
reflect completion. In particular, the incorrect condition caused every
command error to be reported as a timeout.

Add a function that waits for the last command to complete and checks
the status, and use it where appropriate. This prepares for the subsequent
fix of the completion condition in rmi_f34_attention(), which would
previously lead to a timeout instead of a more detailed error message
whenever a command was unsuccessful with v7/v8 bootloaders.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
On Intel platforms the registers for DSP communications are used differently,
the IPC dump information is not correct since important registers are not
printed and existing ones are used a bit differently for IPC4.
As a last step, enable the IPC timeout 'handling' and allow the printout of
the now usefull IPC dump.
