2022-07-28thermal/core: Add thermal_trip in thermal_zoneDaniel Lezcano3-10/+28
The thermal trip points are properties of a thermal zone and the different sub systems should be able to save them in the thermal zone structure instead of having their own definition. Give the opportunity to the drivers to create a thermal zone with thermal trips which will be accessible directly from the thermal core framework. As we added the thermal trip points structure in the thermal zone, let's extend the thermal zone register function to have the thermal trip structures as a parameter and store it in the 'trips' field of the thermal zone structure. The thermal zone contains the trip point, we can store them directly when registering the thermal zone. That will allow another step forward to remove the duplicate thermal zone structure we find in the thermal_of code.

2022-07-28thermal/of: Replace device node match with device node searchDaniel Lezcano1-20/+44
The thermal_of code builds a trip array associated with the node pointer in order to compare the trip point phandle with the list. The thermal trip is a thermal zone property and should be moved there. If some sensors have hardcoded trip points, they should use the exported structure instead of redefining again and again their own structure and data to describe exactly the same things. In order to move this to the thermal.h header and allow more cleanup, we need to remove the node pointer from the structure. Instead of building storing the device node, we search directly in the device tree the corresponding node. That results in a simplification of the code and allows to move the structure to thermal.h Cc: Alexandre Bailon <abailon@baylibre.com> Cc: Kevin Hilman <khilman@baylibre.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linexp.org> Link: https://lore.kernel.org/r/20220722200007.1839356-3-daniel.lezcano@linexp.org Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>

2022-07-28drivers/thermal/cpufreq_cooling : Refactor thermal_power_cpu_get_power tracingLukasz Luba2-37/+9
Simplify the thermal_power_cpu_get_power trace event by removing complicated cpumask and variable length array. Now the tools parsing trace output don't have to hassle to get this power data. The simplified format version uses 'policy->cpu'. Remove also the 'load' information completely since there is very little value of it in this trace event. To get the CPUs' load (or utilization) there are other dedicated trace hooks in the kernel. This patch also simplifies and speeds-up the main cooling code when that trace event is enabled. Rename the trace event to avoid confusion of tools which parse the trace file.

2022-07-28net/funeth: Fix fun_xdp_tx() and XDP packet reclaimDimitris Michailidis3-15/+16
The current implementation of fun_xdp_tx(), used for XPD_TX, is incorrect in that it takes an address/length pair and later releases it with page_frag_free(). It is OK for XDP_TX but the same code is used by ndo_xdp_xmit. In that case it loses the XDP memory type and releases the packet incorrectly for some of the types. Assorted breakage follows. Change fun_xdp_tx() to take xdp_frame and rely on xdp_return_frame() in reclaim.

2022-07-28wait: Fix __wait_event_hrtimeout for RT/DL tasksJuri Lelli1-4/+5
Changes to hrtimer mode (potentially made by __hrtimer_init_sleeper on PREEMPT_RT) are not visible to hrtimer_start_range_ns, thus not accounted for by hrtimer_start_expires call paths. In particular, __wait_event_hrtimeout suffers from this problem as we have, for example: fs/aio.c::read_events wait_event_interruptible_hrtimeout __wait_event_hrtimeout hrtimer_init_sleeper_on_stack <- this might "mode |= HRTIMER_MODE_HARD" on RT if task runs at RT/DL priority hrtimer_start_range_ns WARN_ON_ONCE(!(mode & HRTIMER_MODE_HARD) ^ !timer->is_hard) fires since the latter doesn't see the change of mode done by init_sleeper Fix it by making __wait_event_hrtimeout call hrtimer_sleeper_start_expires, which is aware of the special RT/DL case, instead of hrtimer_start_range_ns.
