2024-10-22platform/x86/amd/hsmp: Convert amd_hsmp_rdwr() to a function pointerSuma Hegde
This is in preparation to ACPI, Non-ACPI split. amd_hsmp_rdwr() is used to access HSMP protocol registers. ACPI and Non-ACPI use different methods to access these registers. Now that code is split and common functionality is kept in hsmp.c we need to define a function pointer to handle these functions separately.

2024-10-17platform/x86: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/platform/x86/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

2024-08-23platform/x86/amd/pmc: Fix SMU command submission path on new AMD platformShyam Sundar S K
The commit 426463d94d45 ("platform/x86/amd/pmc: Send OS_HINT command for new AMD platform") was introduced to enable sending mailbox commands to PMFW on newer platforms. However, it was later discovered that the commit did not configure the correct message port ID (i.e., S2D or PMC). Without this configuration, all command submissions to PMFW are treated as invalid, leading to command failures. To address this issue, the CPU ID association for the new platform needs to be added in amd_pmc_get_ip_info(). This ensures that the correct SMU port IDs are selected.

2024-08-08platform/x86/amd/pmf: Fix to Update HPD Data When ALS is DisabledShyam Sundar S K
If the Ambient Light Sensor (ALS) is disabled, the current code in the PMF driver does not query for Human Presence Detection (HPD) data in amd_pmf_get_sensor_info(). As a result, stale HPD data is used by PMF-TA to evaluate policy conditions, leading to unexpected behavior in the policy output actions. To resolve this issue, modify the PMF driver to query HPD data independently of ALS. Since user_present is a boolean, modify the current code to return true if the user is present and false if the user is away or if the sensor is not detected, and report this status to the PMF TA firmware accordingly. With this change, amd_pmf_get_sensor_info() now returns void instead of int.

2024-04-15platform/x86/amd/pmc: Add AMD MP2 STB functionalityBasavaraj Natikar
AMD MP2 STB function provides a data buffer used to log debug information about the system execution during S2Idle suspend/resume. A data buffer known as the STB (Smart Trace Buffer) is a circular buffer which is a low-level log to assist in debugging by providing insights into any potential hangs or stalls that may occur during the S2Idle suspend/resume processes. The current PMC driver retrieves STB data from MP1, but there can be scenarios where MP1 might hang or become unresponsive, leading to the loss of critical data present in the STB buffer. This defeats the purpose of the STB buffer, which was originally meant to help identify system failures. This feature creates stb_read_previous_boot debugfs allows users to retrieve the STB log from MP2 specifically from the last occurrence of the S2Idle suspend/resume. A userspace daemon can access STB log of last S2Idle suspend/resume which can help to troubleshoot potential issues related to hangs or stalls during the S2Idle suspend/resume sequence.

2024-04-08platform/x86/amd/hsmp: switch to use device_add_groups()Greg Kroah-Hartman
devm_device_add_groups() is being removed from the kernel, so move the hsmp driver to use device_add_groups() instead. The logic is identical, when the device is removed the driver core will properly clean up and remove the groups, and the memory used by the attribute groups will be freed because it was created with dev_* calls, so this is functionally identical overall.
