ASoC: SOF: ipc3-topology: use old pipeline teardown flow with SOF2.1 and older
Originally in commit f951c563283f ("ASoC: SOF: free widgets in
sof_tear_down_pipelines() for static pipelines"), freeing of pipeline
components at suspend was only done with recent FW as there were known
limitations in older firmware versions.
Tests show that if static pipelines are used, i.e. all pipelines are
setup whenever firmware is powered up, the reverse action of freeing all
components at power down, leads to firmware failures with also SOF2.0
and SOF2.1 based firmware.
The problems can be specific to certain topologies with e.g. components
not prepared to be freed at suspend (as this did not happen with older
SOF kernels).
To avoid hitting these problems when kernel is upgraded and used with an
older firmware, bump the firmware requirement to SOF2.2 or newer. If an
older firmware is used, and pipeline is a static one, do not free the
components at suspend. This ensures the suspend flow remains backwards
compatible with older firmware versions. This limitation does not apply
if the product configuration is updated to dynamic pipelines.
The limitation is not linked to firmware ABI, as the interface to free
pipeline components has been available already before ABI3.19. The
problem is in the implementation, so firmware version should be used to
decide whether it is safe to use the newer flow or not. This patch adds
a new SOF_FW_VER() macro to compare SOF firmware release versions.

When the convert-sample-format property was added, the checks got out

not pass any of the other DPCM checks would not go into DPCM mode and

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.

- Use BPF CO-RE (Compile Once, Run Everywhere) to support old kernels
when using bperf (perf BPF based counters) with cgroups.
- Support HiSilicon PCIe Performance Monitoring Unit (PMU), that
monitors bandwidth, latency, bus utilization and buffer occupancy.
Documented in Documentation/admin-guide/perf/hisi-pcie-pmu.rst.
- User space tasks can migrate between CPUs, so when tracing selected
CPUs, system-wide sideband is still needed, fix it in the setup of
Intel PT on hybrid systems.
- Fix metricgroups title message in 'perf list', it should state that
the metrics groups are to be used with the '-M' option, not '-e'.
- Sync the msr-index.h copy with the kernel sources, adding support for
using "AMD64_TSC_RATIO" in filter expressions in 'perf trace' as well
as decoding it when printing the MSR tracepoint arguments.
- Fix program header size and alignment when generating a JIT ELF in
'perf inject'.
- Add multiple new Intel PT 'perf test' entries, including a jitdump
one.
- Fix the 'perf test' entries for 'perf stat' CSV and JSON output when
running on PowerPC due to an invalid topology number in that arch.
- Fix the 'perf test' for arm_coresight failures on the ARM Juno
system.
- Fix the 'perf test' attr entry for PERF_FORMAT_LOST, adding this
option to the or expression expected in the intercepted
perf_event_open() syscall.
- Add missing condition flags ('hs', 'lo', 'vc', 'vs') for arm64 in the

around when the rate constraints are dropped and how they move around
when reparenting clks. Overall it's a much needed improvement to the
clk rate range APIs that used to be pretty broken if you looked
sideways.

Revert "cpumask: fix checking valid cpu range".
This reverts commit b55d5df4cb41 ("cpumask: fix checking valid cpu range").
syzbot is hitting WARN_ON_ONCE(cpu >= nr_cpumask_bits) warning at
cpu_max_bits_warn() [1], for commit b55d5df4cb41 ("cpumask: fix checking
valid cpu range") is broken. Obviously that patch hits WARN_ON_ONCE()
when e.g. reading /proc/cpuinfo because passing "cpu + 1" instead of
"cpu" will trivially hit cpu == nr_cpumask_bits condition.
Although syzbot found this problem in linux-next.git on 2022/09/27 [2],
this problem was not fixed immediately. As a result, that patch was
sent to linux.git before the patch author recognizes this problem, and
syzbot started failing to test changes in linux.git since 2022/10/10
[3].
Andrew Jones proposed a fix for x86 and riscv architectures [4]. But
[2] and [5] indicate that affected locations are not limited to arch
code. More delay before we find and fix affected locations, less tested
kernel (and more difficult to bisect and fix) before release.
We should have inspected and fixed basically all cpumask users before
applying that patch. We should not crash kernels in order to ask
existing cpumask users to update their code, even if limited to
CONFIG_DEBUG_PER_CPU_MAPS=y case.
There is an outstanding binutils issue to support a non-constant operand
to .sleb128 and .uleb128 in GAS for RISC-V but there does not appear to
be any movement on it, due to concerns over how it would work with
linker relaxation.
To avoid these build errors, prevent DWARF5 from being selected when
using clang and an assembler that does not have support for these symbol
deltas, which can be easily checked in Kconfig with as-instr plus the
small test program from the dwz test suite from the binutils issue.

This ioctl improves upon CIFS_IOC_NOTIFY by returning the notify

filter flags and the file_notify_information structure returned.

various commands. For example say -A (i.e, AGGR_NONE mode), expects 7
fields in the output having "CPU" as first field. Same way, for

The testcases compares the result with expected count.
The values for socket, die, core and cpu are fetched from topology
directory:
/sys/devices/system/cpu/cpu*/topology.
For example, socket value is fetched from "physical_package_id" file of
topology directory. (cpu__get_topology_int() in util/cpumap.c)
If a platform fails to fetch the topology information, values will be
set to -1. For example, incase of pSeries platform of powerpc, value for
"physical_package_id" is restricted and not exposed. So, -1 will be
assigned.
Perf code has a checks for valid cpu id in "aggr_printout"
(stat-display.c), which displays the fields. So, in cases where topology
values not exposed, first field of the output displaying will be empty.
This cause the testcase to fail, as it counts number of fields in the
output.
Incase of -A (AGGR_NONE mode,), testcase expects 7 fields in the output,
becos of -1 value obtained from topology files for some, only 6 fields
are printed. Hence a testcase failure reported due to mismatch in number
of fields in the output.
Patch here adds a sanity check in the testcase for topology. Check will
help to skip the test if -1 value found.

output.
Incase of -A (AGGR_NONE mode,), testcase expects 7 fields in the output,
becos of -1 value obtained from topology files for some, only 6 fields
are printed. Hence a testcase failure reported due to mismatch in number
of fields in the output.
Patch here adds a sanity check in the testcase for topology. Check will
help to skip the test if -1 value found.

clk: tegra: Fix Tegra PWM parent clock
Commit efa4a7e19dd5 ("pwm: tegra: Optimize period calculation") updated
the period calculation in the Tegra PWM driver and now returns an error
if the period requested is less than minimum period supported. This is
breaking PWM support on various Tegra platforms. For example, on the
Tegra210 Jetson Nano platform this is breaking the PWM fan support and
probing the PWM fan driver now fails ...
pwm-fan pwm-fan: Failed to configure PWM: -22
pwm-fan: probe of pwm-fan failed with error -22
The problem is that the default parent clock for the PWM on Tegra210 is
a 32kHz clock and is unable to support the requested PWM period.
Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by
updating the parent clock for the PWM to be the PLL_P.

clk: qcom: gcc-msm8660: Drop hardcoded fixed board clocks
These two clocks are now registered in the device tree as fixed clocks,
causing a regression in the driver as the clock already exists with
e.g. the name "pxo_board" as the MSM8660 GCC driver probes.
Fix this by just not hard-coding this anymore and everything works
like a charm.
Since commit 3c0c969b9c03 ("clk: Stop forwarding clk_rate_requests
to the parent"), the clk_rate_request is .. as the title says, not
forwarded anymore to the parent: this produces an issue with the
MediaTek clock MUX driver during GPU DVFS on MT8195, but not on
MT8192 or others.
This is because, differently from others, like MT8192 where all of
the clocks in the MFG parents tree are of mtk_mux type, but in the
parent tree of MT8195's MFG clock, we have one mtk_mux clock and
one (clk framework generic) mux clock, like so:
To solve this issue and also keep the GPU DVFS clocks code working
as expected, wire up a .determine_rate() callback for the mtk_mux
ops; for that, the standard clk_mux_determine_rate_flags() was used
as it was possible to.
This commit was successfully tested on MT6795 Xperia M5, MT8173 Elm,
MT8192 Spherion and MT8195 Tomato; no regressions were seen.
For the sake of some more documentation about this issue here's the
trace of it:
The rule for generating human readable LLVM IR (.ll) is only useful as a
debugging feature:
$ make LLVM=1 fs/select.ll
As Fangrui notes:
A LLVM_ENABLE_ASSERTIONS=off build of Clang defaults to
-fdiscard-value-names.
A LLVM_ENABLE_ASSERTIONS=on build of Clang defaults to
-fno-discard-value-names.
Explicitly enable -fno-discard-value-names so that the IR always contains
value names regardless of whether assertions were enabled or not.
Assertions generally are not enabled in releases of clang packaged by
distributions.
