When the hardware interrupt processing function is executed, the interrupt and
preemption of current cpu are disabled. As a result, the task is suspended.
The execution of the hardware processing function takes a long time
(for example 5 ms), will affect the task scheduling performance.

Add 'perf irq' to trace/measure the hardware interrupts.
Now three functions are provided:
1. 'perf irq record ' to record the irq handler events.
2. 'perf irq script' to see a detailed trace of the workload that
was recorded.
3. 'perf irq timeconsume' to calculate the time consumed by

It makes it harder to comment when I'm not on cc.
Hint, hint... ;)
core->dev_dec and core-dev->enc are set up
by the corresponding vdec_probe and venc_probe.
If the probe fails, they will not be set
and so could be null when venus_sys_error_handler

Modifies CONFIG_DEBUG_INFO_DWARF4 to be a member of a choice. Adds an
explicit CONFIG_DEBUG_INFO_DWARF2, which is the default. Does so in a
way that's forward compatible with existing configs, and makes adding
future versions more straightforward.

This enables the use of per-task stack canary values if GCC has
support for emitting the stack canary reference relative to the
value of tp, which holds the task struct pointer in the riscv

Configuration was correct enough to work with the pre-configuration done by
uboot. While at it, also document the location.

This patch has conflicts with the series "Decouple Mediatek DRM sub
driver" [1] which has been applied to mediatek-drm-next, so please
rebase this patch onto mediatek-drm-next.

The Awinic AW9523(B) is a multi-function I2C gpio expander in a
TQFN-24L package, featuring PWM (max 37mA per pin, or total max
power 3.2Watts) for LED driving capability.
It has two ports with 8 pins per port (for a total of 16 pins),
configurable as either PWM with 1/256 stepping or GPIO

In this series, why only gamma and color add pm runtime support? I
think all ddp component need pm runtime support. And pm runtime
support is not related to mt8192, so move these patches

Add utilities to new/free an ids hashmap, as well as to union. Add
testing of the union. Unioning hashmaps will be used when parsing the
metric, if a value is known then the hashmap is unnecessary, otherwise
we need to union together all the event ids to compute their values for
reporting.
ABS_PRESSURE and ABS_MT_PRESSURE on touch devices usually represent
contact size (as a finger flattens with higher pressure the contact size
increases) and userspace translates the kernel pressure value back into
contact size. For example, libinput has pressure thresholds when a touch is
If during computing a metric an event (id) is missing the parsing
aborts. A later patch will make it so that events that aren't used in
the output are deliberately omitted, in which case we don't want the
abort. Modify the missing ID case to report NAN for these cases.

A later change to parsing the ids out (in expr__find_other) will
potentially drop hashmaps and so it is more convenient to move
expr_parse_ctx to have a hashmap pointer rather than a struct value. As
this pointer must be freed, rather than just going out of scope,
add expr__ctx_new and

I can't imagine when or why `current' would return a NULL pointer. This
