The legacy PCI interrupt is no longer supported for processor thermal device on Lunar Lake. The support is via MSI. Add feature PROC_THERMAL_FEATURE_MSI_SUPPORT to support MSI feature per generation. Define this feature for Lunar Lake processors. There are 4 MSI sources: 0 - Package thermal 1 - DDR Thermal 2 - Power floor interrupt 3 - Workload type hint On interrupt, check the source and call the corresponding handler. Here don't need to call proc_thermal_check_wt_intr() and proc_thermal_check_power_floor_intr() to check if the interrupt is for those sources as there is a dedicated MSI interrupt.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
