Subject: ACPI / processor: Request native thermal interrupt handling via _OSC
|
||||
Origin: https://git.kernel.org/linus/a21211672c9a1d730a39aa65d4a5b3414700adfb
|
||||
Bug-Debian: https://bugs.debian.org/817016
|
||||
|
||||
There are several reports of freeze on enabling HWP (Hardware PStates)
|
||||
feature on Skylake-based systems by the Intel P-states driver. The root
|
||||
cause is identified as the HWP interrupts causing BIOS code to freeze.
|
||||
|
||||
HWP interrupts use the thermal LVT which can be handled by Linux
|
||||
natively, but on the affected Skylake-based systems SMM will respond
|
||||
to it by default. This is a problem for several reasons:
|
||||
- On the affected systems the SMM thermal LVT handler is broken (it
|
||||
will crash when invoked) and a BIOS update is necessary to fix it.
|
||||
- With thermal interrupt handled in SMM we lose all of the reporting
|
||||
features of the arch/x86/kernel/cpu/mcheck/therm_throt driver.
|
||||
- Some thermal drivers like x86-package-temp depend on the thermal
|
||||
threshold interrupts signaled via the thermal LVT.
|
||||
- The HWP interrupts are useful for debugging and tuning
|
||||
performance (if the kernel can handle them).
|
||||
The native handling of thermal interrupts needs to be enabled
|
||||
because of that.
|
||||
|
||||
This requires some way to tell SMM that the OS can handle thermal
|
||||
interrupts. That can be done by using _OSC/_PDC in processor
|
||||
scope very early during ACPI initialization.
|
||||
|
||||
The meaning of _OSC/_PDC bit 12 in processor scope is whether or
|
||||
not the OS supports native handling of interrupts for Collaborative
|
||||
Processor Performance Control (CPPC) notifications. Since on
|
||||
HWP-capable systems CPPC is a firmware interface to HWP, setting
|
||||
this bit effectively tells the firmware that the OS will handle
|
||||
thermal interrupts natively going forward.
|
||||
|
||||
For details on _OSC/_PDC refer to:
|
||||
http://www.intel.com/content/www/us/en/standards/processor-vendor-specific-acpi-specification.html
|
||||
|
||||
To implement the _OSC/_PDC handshake as described, introduce a new
|
||||
function, acpi_early_processor_osc(), that walks the ACPI
|
||||
namespace looking for ACPI processor objects and invokes _OSC for
|
||||
them with bit 12 in the capabilities buffer set and terminates the
|
||||
namespace walk on the first success.
|
||||
|
||||
Also modify intel_thermal_interrupt() to clear HWP status bits in
|
||||
the HWP_STATUS MSR to acknowledge HWP interrupts (which prevents
|
||||
them from firing continuously).
