18 months agomfd: ocelot-spi: Fix unsupported bulk read
Colin Foster [Wed, 22 Mar 2023 14:11:30 +0000 (07:11 -0700)]
mfd: ocelot-spi: Fix unsupported bulk read

Ocelot chips (VSC7511, VSC7512, VSC7513, VSC7514) don't support bulk read
operations over SPI.

Many SPI buses have hardware that can optimize consecutive reads.
Essentially an address is written to the chip, and if the SPI controller
continues to toggle the clock, subsequent register values are reported.
This can lead to significant optimizations, because the time between
"address is written to the chip" and "chip starts to report data" can often
take a fixed amount of time.

When support for Ocelot chips were added in commit f3e893626abe ("mfd:
ocelot: Add support for the vsc7512 chip via spi") it was believed that
this optimization was supported. However it is not.

Most register transactions with the Ocelot chips are not done in bulk, so
this bug could go unnoticed. The one scenario where bulk register
operations _are_ performed is when polling port statistics counters, which
was added in commit d87b1c08f38a ("net: mscc: ocelot: use bulk reads for
stats").

Things get slightly more complicated here...

A bug was introduced in commit d4c367650704 ("net: mscc: ocelot: keep
ocelot_stat_layout by reg address, not offset") that broke the optimization
of bulk reads. This means that when Ethernet support for the VSC7512 chip
was added in commit 3d7316ac81ac ("net: dsa: ocelot: add external ocelot
switch control") things were actually working "as expected".

The bulk read opmtimization was discovered, and fixed in commit
6acc72a43eac ("net: mscc: ocelot: fix stats region batching") and the
timing optimizations for SPI were noticed. A bulk read went from ~14ms to
~2ms. But this timing improvement came at the cost of every register
reading zero due the fact that bulk reads don't work.

The read timings increase back to 13-14ms, but that's a price worth paying
in order to receive valid data. This is verified in a DSA setup (cpsw-new
switch tied to port 0 on the VSC7512, after having been running overnight)

mfd: max597x: Add support for MAX5970 and MAX5978

Implement a regulator driver with IRQ support for fault management.
Written against documentation [1] and [2] and tested on real hardware.

Every channel has it's own regulator supply nammed 'vss1-supply' and
'vss2-supply'. The regulator supply is used to determine the output
voltage, as the smart switch provides no output regulation.
The driver requires the 'shunt-resistor-micro-ohms' to be present in
the devicetree to properly calculate current related values.

You must specify compatible devictree layout:

regulator@3a {
        reg = <0x3a>;
        vss1-supply = <&p3v3>;
        compatible = "maxim,max5978";

        ...

                sw0_ref: SW0 {
                        regulator-compatible = "SW0";
                        shunt-resistor-micro-ohms = <12000>;

Aidan MacDonald [Thu, 16 Feb 2023 22:22:11 +0000 (22:22 +0000)]
mfd: qcom-pm8008: Fix swapped mask/unmask in irq chip

The usual behavior of mask registers is writing a '1' bit to
disable (mask) an interrupt; similarly, writing a '1' bit to
an unmask register enables (unmasks) an interrupt.

Due to a longstanding issue in regmap-irq, mask and unmask
registers were inverted when both kinds of registers were
present on the same chip, ie. regmap-irq actually wrote '1's
to the mask register to enable an IRQ and '1's to the unmask
register to disable an IRQ.

This was fixed by commit e8ffb12e7f06 ("regmap-irq: Fix
inverted handling of unmask registers") but the fix is opt-in
via mask_unmask_non_inverted = true because it requires manual
changes for each affected driver. The new behavior will become
the default once all drivers have been updated.

The PM8008 appears to rely on the inverted behavior. It has
separate set & clear registers for a register called INT_EN,
which presumably enables interrupts by writing '1's. Opt in
to the new non-inverted behavior & swap mask_base/unmask_base.

When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android

tracing/hwlat: Replace sched_setaffinity with set_cpus_allowed_ptr

There is a problem with the behavior of hwlat in a container,
resulting in incorrect output. A warning message is generated:
"cpumask changed while in round-robin mode, switching to mode none",
and the tracing_cpumask is ignored. This issue arises because
the kernel thread, hwlatd, is not a part of the container, and
the function sched_setaffinity is unable to locate it using its PID.
Additionally, the task_struct of hwlatd is already known.
Ultimately, the function set_cpus_allowed_ptr achieves
the same outcome as sched_setaffinity, but employs task_struct
instead of PID.

Test case:

  # cd /sys/kernel/tracing
  # echo 0 > tracing_on
  # echo round-robin > hwlat_detector/mode
  # echo hwlat > current_tracer

tracing: Fix wrong return in kprobe_event_gen_test.c

Overwriting the error code with the deletion result may cause the
function to return 0 despite encountering an error. Commit b111545d26c0
("tracing: Remove the useless value assignment in

returning the original error code, so this patch does the same.

19 months agomedia: m5mols: fix off-by-one loop termination error
Linus Torvalds [Fri, 17 Mar 2023 20:51:17 +0000 (13:51 -0700)]
media: m5mols: fix off-by-one loop termination error

The __find_restype() function loops over the m5mols_default_ffmt[]
array, and the termination condition ends up being wrong: instead of
stopping when the iterator becomes the size of the array it traverses,
it stops after it has already overshot the array.

Now, in practice this doesn't likely matter, because the code will
always find the entry it looks for, and will thus return early and never
hit that last extra iteration.

But it turns out that clang will unroll the loop fully, because it has
only two iterations (well, three due to the off-by-one bug), and then
clang will end up just giving up in the middle of the loop unrolling
when it notices that the code walks past the end of the array.

And that made 'objtool' very unhappy indeed, because the generated code
just falls off the edge of the universe, and ends up falling through to
the next function, causing this warning:

   drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc()

Fix the loop ending condition.
