2025-05-08	platform/x86:intel/vsec: Change return type of intel_vsec_register	Xi Pardee	1	-2/+3
	Change return type of intel_vsec_register() to int. The current implementation does not indicate if the register fail or not. Change to return error code if it fails or if INTEL_VSEC config is not set. This is a preparation step to introduce a new SSRAM Telemetry driver that will be using this API.

2024-11-14	platform/x86/intel/pmt: allow user offset for PMT callbacks	Michael J. Ruhl	1	-1/+2
	Usage of the telem sysfs file allows for partial reads at an offset. The current callback method returns the buffer starting from offset 0 only. Include the requested offset in the callback and update the necessary address calculations with the offset. Note: offset addition is moved from the caller to the local usage. For non-callback usage this is unchanged behavior.

2024-08-12	platform/x86/intel/vsec: Add PMT read callbacks	David E. Box	1	-0/+15
	Some PMT providers require device specific actions before their telemetry can be read. Provide assignable PMT read callbacks to allow providers to perform those actions.

2024-08-12	platform/x86/intel/vsec.h: Move to include/linux	David E. Box	1	-0/+134
	Some drivers outside of PDX86 need access to the vsec header. Move it to include/linux to make it easier to include.
