mainline:701d40af59373ac3a60c620cbd0ceff7b2b8e565 severity: Moderate upstream commit 701d40a ("platform/x86/intel/vsec: Remove nuisance message") intel_vsec_walk_header() is used to configure features from devices that don't provide a PCI VSEC or DVSEC structure. Some of these features may be unsupported and fail to load. Ignore them silently as we do for unsupported features described by VSEC/DVSEC.

mainline:e6ba4acde44957dc9bdc3222b5739217a102752d severity: Moderate upstream commit e6ba4ac ("platform/x86/intel/pmc/lnl: Remove SSRAM support") A recent PMC firmware change in Lunar Lake caused the pmc_core driver to fail to probe. This is due to a change in the GUID for PMC telemetry coming from the SSRAM device. Until a final release is ready this value may change again. In the meantime, disable the SSRAM support for Lunar Lake so the driver can load and provide some basic functionality.

mainline:ac2d1fd9688fcdfba5acc815fb2b13fec83e5dad severity: Moderate upstream commit ac2d1fd ("platform/x86/intel/pmc/arl: Put GNA device in D3") As is the case on Meteor Lake, the Gaussian & Neural Accelerator (GNA) device is powered by BIOS to D0 by default. If no driver is loaded, this will cause the Package C state to be limited to PC2, leading to significant power consumption and decrease in batter life. Put the GNA device in D3 by default if no driver is loaded for it.
