x86/amd_nb: Move SMN access code to a new amd_node driverSMN access was bolted into amd_nb mostly as convenience. This haslimitations though that require incurring tech debt to keep it working.Move SMN access to the newly introduced AMD Node driver.Signed-off-by: Mario Limonciello Signed-off-by: Yazen Ghannam Signed-off-by: Borislav Petkov (AMD) Acked-by: Ilpo Järvinen # pdx86Acked-by: Shyam Sundar S K # PMF, PMCLink: https://lore.kernel.org/r/20241206161210.163701-11-yazen.ghannam@amd.com List of files: /linux-6.15/drivers/platform/x86/amd/pmc/Kconfig

2dc77993 - platform/x86/amd/pmc: Add AMD MP2 STB functionality

Thu, 04 Apr 2024 09:07:02 +0000

platform/x86/amd/pmc: Add AMD MP2 STB functionalityAMD MP2 STB function provides a data buffer used to log debug informationabout the system execution during S2Idle suspend/resume.A data buffer known as the STB (Smart Trace Buffer) is a circular bufferwhich is a low-level log to assist in debugging by providing insightsinto any potential hangs or stalls that may occur during the S2Idlesuspend/resume processes.The current PMC driver retrieves STB data from MP1, but there can bescenarios where MP1 might hang or become unresponsive, leading to theloss of critical data present in the STB buffer. This defeats the purposeof the STB buffer, which was originally meant to help identify systemfailures.This feature creates stb_read_previous_boot debugfs allows users toretrieve the STB log from MP2 specifically from the last occurrence ofthe S2Idle suspend/resume. A userspace daemon can access STB log of lastS2Idle suspend/resume which can help to troubleshoot potential issuesrelated to hangs or stalls during the S2Idle suspend/resume sequence.Reviewed-by: Shyam Sundar S K Signed-off-by: Basavaraj Natikar Reviewed-by: Kuppuswamy Sathyanarayanan Link: https://lore.kernel.org/r/20240404090702.325838-1-Basavaraj.Natikar@amd.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/x86/amd/pmc/Kconfig
