Thermal: Intel SoC DTS: Translate IO-APIC GSI number to linux irq number

2018-07-26T08:02:48+00:00

The Intel SoC DTS uses a hardcoded GSI number, before this commit
it was passing it to request_irq as if it were a linux irq number,
but there is no 1:1 mapping so in essence it was requesting a
random interrupt.

Besides this causing the DTS driver to not actually get an interrupt
if the thermal thresholds are exceeded this also is causing an
interrupt conflict on some devices since the linux irq 86 which is
being requested is already in use, leading to oopses like this:

genirq: Flags mismatch irq 86. 00002001 (soc_dts) vs. 00000083 (volume_down)
CPU: 0 PID: 601 Comm: systemd-udevd Tainted: G         C OE     4.17.0-rc6+ #45
Hardware name: Insyde i86/Type2 - Board Product Name, BIOS CHUWI.D86JLBNR03 01/14/2015
Call Trace:
  dump_stack+0x5c/0x80
  __setup_irq.cold.50+0x4e/0xac

  request_threaded_irq+0xf5/0x160
  ? 0xffffffffc0a93000
  intel_soc_thermal_init+0x74/0x1000 [intel_soc_dts_thermal]

This commit makes the intel_soc_dts_thermal.c code call
acpi_register_gsi() to translate the hardcoded IO-APIC GSI number (86)
to a linux irq, so that the dts code uses the right interrupt and we
no longer get an oops about an irq conflict.

thermal: Add cooling device's statistics in sysfs

2018-04-02T13:49:01+00:00

This extends the sysfs interface for thermal cooling devices and exposes
some pretty useful statistics. These statistics have proven to be quite
useful specially while doing benchmarks related to the task scheduler,
where we want to make sure that nothing has disrupted the test,
specially the cooling device which may have put constraints on the CPUs.
The information exposed here tells us to what extent the CPUs were
constrained by the thermal framework.

The write-only "reset" file is used to reset the statistics.

The read-only "time_in_state_ms" file shows the time (in msec) spent by the
device in the respective cooling states, and it prints one line per
cooling state.

The read-only "total_trans" file shows single positive integer value
showing the total number of cooling state transitions the device has
gone through since the time the cooling device is registered or the time
when statistics were reset last.

The read-only "trans_table" file shows a two dimensional matrix, where
an entry  (row i, column j) represents the number of transitions
from State_i to State_j.

This is how the directory structure looks like for a single cooling
device:

$ ls -R /sys/class/thermal/cooling_device0/
/sys/class/thermal/cooling_device0/:
cur_state  max_state  power  stats  subsystem  type  uevent

/sys/class/thermal/cooling_device0/power:
autosuspend_delay_ms  runtime_active_time  runtime_suspended_time
control               runtime_status

/sys/class/thermal/cooling_device0/stats:
reset  time_in_state_ms  total_trans  trans_table

This is tested on ARM 64-bit Hisilicon hikey620 board running Ubuntu and
ARM 64-bit Hisilicon hikey960 board running Android.

thermal: armada: Update Kconfig and module description

2018-01-01T21:21:48+00:00

Update Armada thermal driver Kconfig entry as well as the driver's
MODULE_DESCRIPTION content, now that 64-bit SoCs are also supported,
eg. Armada 7K and Armada 8K.

Use the generic term "Marvell EBU Armada SoCs" instead of listing all
the supported SoCs everywhere (excepted in the Kconfig description,
where it is useful to have a list).

thermal: add brcmstb AVS TMON driver

2017-11-01T02:32:19+00:00

The AVS TMON core provides temperature readings, a pair of configurable
high- and low-temperature threshold interrupts, and an emergency
over-temperature chip reset. The driver utilizes the first two to
provide temperature readings and high-temperature notifications to
applications. The over-temperature reset is not exposed to
applications; this reset threshold is critical to the system and should
be set with care within the bootloader.

Applications may choose to utilize the notification mechanism, the
temperature reading mechanism (e.g., through polling), or both.

thermal: enable broadcom menu for arm64 bcm2835

2017-11-01T02:32:13+00:00

Moving the bcm2835 thermal driver to the broadcom directory prevented it
from getting enabled for arm64 builds, since the broadcom directory is only
available when 32-bit specific ARCH_BCM is set.

Fix this by enabling the Broadcom menu for ARCH_BCM or ARCH_BCM2835.

thermal: imx: add NVMEM dependency

2017-10-18T02:24:13+00:00

The driver now fails to link into vmlinux when CONFIG_NVMEM is a loadable
module:

drivers/thermal/imx_thermal.o: In function `imx_thermal_probe':
imx_thermal.c:(.text+0x360): undefined reference to `nvmem_cell_read_u32'

imx_thermal.c:(.text+0x388): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `nvmem_cell_read_u32'

This adds a Kconfig dependency to force it to be a module as well
when its dependency is loadable.
