The cleanup is done by devres in irq_uninstall.
Commit bbc9651fe9 ("drm/xe/irq: move irq_uninstall over to devm")
resolved the ordering issue where irq_uninstall (registered with drmm)
was called after pci_free_irq_vectors (registered with devm upon calling
pci_alloc_irq_vectors). This happened because drmm action list is
registered with devm very early in the init flow - before
pci_alloc_irq_vectors.
Now that irq_uninstall is registered with devm, it will be called before
pci_free_irq_vectors and we can remove xe_irq_shutdown.

The "Core Performance Boost (CPB) feature, when enabled in the BIOS,
allows the OS to control the highest performance for each individual
core. The active, passive and the guided modes of the amd-pstate driver
do support controlling the core frequency boost when this BIOS feature
is enabled. Additionally, the amd-pstate driver provides a sysfs
interface allowing the user to activate/deactivate this core performance
boost feature at runtime.
Add support for the set_boost callback in the active mode driver to
enable boost control via the cpufreq core. This ensures a consistent
boost control interface across all pstate modes, including passive
mode, guided mode, and active mode.
With this addition, all three pstate modes can support the same boost
control interface with unique interface and global CPB control. Each
CPU also supports individual boost control, allowing global CPB to
change all cores' boost states simultaneously. Specific CPUs can
update their boost states separately, ensuring all cores' boost
states are synchronized.

a global function as an argument. The adverse effects of this is that
BPF helpers can continue to make use of this modified
CONST_PTR_TO_DYNPTR from within the context of the global function,
which can unintentionally result in out-of-bounds memory accesses and
therefore compromise overall system stability i.e.

The python build now depends on libraries and doesn't use
python-ext-sources except for the util/python.c dependency. Switch to
just directly depending on that file and util/setup.py. This allows
the removal of python-ext-sources.

setup.py was building most perf sources causing setup.py to mimic the
Makefile logic as well as flex/bison code to be stubbed out, due to
complexity building. By using libraries fewer functions are stubbed
out, the build is faster and the Makefile logic is reused which should
simplify updating. The libraries are passed through LDFLAGS to avoid
complexity in python.
Force the -fPIC flag for libbpf.a to ensure it is suitable for linking
into the perf python module.

Make the util directory into its own library. This is done to avoid
compiling code twice, once for the perf tool and once for the perf
python module. For convenience:
arch/common.c
scripts/perl/Perf-Trace-Util/Context.c
scripts/python/Perf-Trace-Util/Context.c
are made part of this library.

The currently existing of_property_present check for interrupts does not
cover all ways interrupts can be defined in a device tree, e.g.
"interrupts-extended".
In order to support all current and future ways that can be done, drop that
check and call of_irq_parse_one to figure out if an interrupt is defined
and irq_create_of_mapping for the actual mapping and let it be handled by
the interrupt subsystem.

platform_get_resource_byname() will return NULL which is later
dereferenced. According to sound/qcom,lpass-cpu.yaml, these resources
are provided, but DT can be broken due to any error. In such cases driver
must be able to protect itself, since the DT is external data for the
driver.
Adjust this issues by adding NULL return check.
