Some of the future Intel platforms will require reading the RAPL
counters via perf and not MSR. On current platforms we can still read
them using both ways.

If user request --no-msr or is not able to access the MSRs,
turbostat should clear all the counters added with --add.
Because MSR access permission checks are done after the cmdline is
parsed, the decision has to be defered up until the transition into
no-msr mode happen.

Checking early if the permissions are even needed gets rid of the
warnings about some of them missing. Earlier we issued a warning in case
of missing MSR and/or perf permissions, even when user never asked for
counters that require those.

By using the perf API we spend less time in between the reads of the
counters, resulting in more accurate calculations of the dependent
metrics.
Using perf API is also usually faster overall, although cache miss, if
we get one, is more costly when using perf vs MSR driver.
We would fallback to the msr reads if the sysfs isn't there or when in
--no-perf mode.

Previously a failed read of /dev/cpu_dma_latency erroneously complained
turbostat: capget(CAP_SYS_ADMIN) failed, try "# setcap cap_sys_admin=ep ./turbostat
This went unnoticed because this file is typically visible to root,
and turbostat was typically run as root.
Going forward, when a non-root user can run turbostat...
Complain about failed read access to this file only if --debug is used.

turbostat prints the abnormal SYS%LPI across suspend-to-idle:
SYS%LPI = 114479815993277.50
This is reproduced by:
Run a freeze cycle, e.g. "sleepgraph -m freeze -rtcwake 15".
Then do a reboot. After boot up, launch the suspend-idle-idle
and check the SYS%LPI field.
The slp_so residence counter is in LPIT table, and BIOS does not
clears this register across reset. The PMC expects the OS to calculate
the LPI residency based on the delta. However, there is an firmware
issue that the LPIT gets cleared to 0 during the second suspend
to idle after the reboot, which brings negative delta value.

When running turbostat, a system with 512 cpus reaches the limit for
maximum number of file descriptors that can be opened. To solve this
problem, the limit is raised to 2^15, which is a large enough number.
Below data is collected from AMD server systems while running turbostat:
|-----------+-------------------------------|
| # of cpus | # of opened fds for turbostat |
|-----------+-------------------------------|
| 128 | 260 |
|-----------+-------------------------------|
| 192 | 388 |
|-----------+-------------------------------|
| 512 | 1028 |
|-----------+-------------------------------|
So, the new max limit would be sufficient up to 2^14 cpus (but this
also depends on how many counters are enabled).

|
|
Since commit aa49c90894d0 ("i2c: core: Run atomic i2c xfer when
!preemptible"), the whole reboot/power off sequence on non-preempt kernels
is using atomic i2c xfer, as !preemptible() always results to 1.
During device_shutdown(), the i2c might be used a lot and not all busses
have implemented an atomic xfer handler. This results in a lot of
avoidable noise, like:
[ 12.687169] No atomic I2C transfer handler for 'i2c-0'
[ 12.692313] WARNING: CPU: 6 PID: 275 at drivers/i2c/i2c-core.h:40 i2c_smbus_xfer+0x100/0x118
...
Fix this by allowing non-atomic xfer when the interrupts are enabled, as
it was before.

ASM108x/VT630x PCIe cards
VIA VT6306/6307/6308 provides PCI interface compliant to 1394 OHCI. When
the hardware is combined with Asmedia ASM1083/1085 PCIe-to-PCI bus bridge,
it appears that accesses to its 'Isochronous Cycle Timer' register (offset
0xf0 on PCI memory space) often causes unexpected system reboot in any
type of AMD Ryzen machine (both 0x17 and 0x19 families). It does not
appears in the other type of machine (AMD pre-Ryzen machine, Intel
machine, at least), or in the other OHCI 1394 hardware (e.g. Texas
Instruments).
The issue explicitly appears at a commit dcadfd7f7c74 ("firewire: core:
use union for callback of transaction completion") added to v6.5 kernel.
It changed 1394 OHCI driver to access to the register every time to
dispatch local asynchronous transaction. However, the issue exists in
older version of kernel as long as it runs in AMD Ryzen machine, since
the access to the register is required to maintain bus time. It is not
hard to imagine that users experience the unexpected system reboot when
generating bus reset by plugging any devices in, or reading the register
by time-aware application programs; e.g. audio sample processing.
This commit suppresses the unexpected system reboot in the combination of
hardware. It avoids the access itself. As a result, the software stack can
not provide the hardware time anymore to unit drivers, userspace
applications, and nodes in the same IEEE 1394 bus. It brings apparent
disadvantage since time-aware application programs require it, while
time-unaware applications are available again; e.g. sbp2.

Turns out that one of the ways that Nvidia's driver handles the pre-LT
timeout for eDP panels is by providing a retry timeout in their link
training callbacks that we're expected to wait for. Up until now we didn't
pay any attention to this parameter.
So, start honoring the timeout if link training fails - and retry up to 3
times. The "3 times" bit comes from OpenRM's link training code.

There is a deadlock between the irq and fctx locks,
the irq handling takes irq then fctx lock
the fence signalling takes fctx then irq lock
This splits the fence signalling path so the code that hits
the irq lock is done in a separate work queue.
This seems to fix crashes/hangs when using nouveau gsp with

Currently we get an error from ACPI because both of these arguments expect
a single argument, and we don't provide one. I'm not totally clear on what
that argument does, but we're able to find the missing value from
_acpiCacheMethodData() in src/kernel/platform/acpi_common.c in nvidia's

This func ptr here is normally static allocation, but gsp r535
uses a dynamic pointer, so we need to handle that better.
This fixes a crash with GSP when you use config=disp=0 to avoid
disp problems.

Add NULL callbacks for some things GSP calls that we don't handle, but know about
so we avoid the logging.
v2: Timur suggested allowing null fn.

Pull networking fixes from Jakub Kicinski:
"Including fixes from wireless and netfilter.
We haven't accumulated much over the break. If it wasn't for the
uninterrupted stream of fixes for Intel drivers this PR would be very
slim. There was a handful of user reports, however, either they stood
out because of the lower traffic or users have had more time to test
over the break. The ones which are v6.7-relevant should be wrapped up.
Current release - regressions:
- Revert "net: ipv6/addrconf: clamp preferred_lft to the minimum
required", it caused issues on networks where routers send prefixes
with preferred_lft=0
- wifi:
- iwlwifi: pcie: don't synchronize IRQs from IRQ, prevent deadlock
- mac80211: fix re-adding debugfs entries during reconfiguration
Current release - new code bugs:
- tcp: print AO/MD5 messages only if there are any keys
Previous releases - regressions:
- virtio_net: fix missing dma unmap for resize, prevent OOM
Previous releases - always broken:
- mptcp: prevent tcp diag from closing listener subflows
- nf_tables:
- set transport header offset for egress hook, fix IPv4 mangling
- skip set commit for deleted/destroyed sets, avoid double deactivation
- nat: make sure action is set for all ct states, fix openvswitch
matching on ICMP packets in related state
- eth: mlxbf_gige: fix receive hang under heavy traffic

Commit 688eb8191b47 ("x86/csum: Improve performance of `csum_partial`")
ended up improving the code generation for the IP csum calculations, and
in particular special-casing the 40-byte case that is a hot case for
IPv6 headers.
It then had _another_ special case for the 64-byte unrolled loop, which
did two chains of 32-byte blocks, which allows modern CPU's to improve
performance by doing the chains in parallel thanks to renaming the carry
flag.
This just unifies the special cases and combines them into just one
single helper the 40-byte csum case, and replaces the 64-byte case by a
80-byte case that just does that single helper twice. It avoids having
all these different versions of inline assembly, and actually improved
performance further in my tests.
There was never anything magical about the 64-byte unrolled case, even
though it happens to be a common size (and typically is the cacheline
size).

The special case for odd aligned buffers is unnecessary and mostly
just adds overhead. Aligned buffers is the expectations, and even for
unaligned buffer, the only case that was helped is if the buffer was
1-byte from word aligned which is ~1/7 of the cases. Overall it seems
highly unlikely to be worth to extra branch.
It was left in the previous perf improvement patch because I was
erroneously comparing the exact output of `csum_partial(...)`, but
really we only need `csum_fold(csum_partial(...))` to match so its
safe to remove.
All csum kunit tests pass.
