platform/x86/amd/pmc: Move PMC driver to separate directory

2023-08-23T15:31:26Z

With latest commits having PMC code spread across multiple files, it would be easier to maintain them in a separate directory under amd/pmc.

platform/x86/amd: pmc: Utilize SMN index 0 for driver probe

2023-04-11T08:37:27Z

The current SMN index used for the driver probe seems to be meant for the BIOS pair and there are potential concurrency problems that can occur with an inopportune SMI. It is been advised to use SMN_INDEX_0 instead of SMN_INDEX_2, which is what amd_nb.c provides and this function has protections to ensure that only one caller can use it at a time.

platform/x86/amd: pmc: add CONFIG_SERIO dependency

2023-01-30T13:37:22Z

Using the serio subsystem now requires the code to be reachable: x86_64-linux-ld: drivers/platform/x86/amd/pmc.o: in function `amd_pmc_suspend_handler': pmc.c:(.text+0x86c): undefined reference to `serio_bus' Add the usual dependency: as other users of serio use 'select' rather than 'depends on', use the same here.

platform/x86/amd/pmf: Add support for PMF core layer

2022-08-15T11:23:37Z

PMF core layer is meant to abstract the common functionalities across PMF features. This layer also does the plumbing work like setting up the mailbox channel for the communication between the PMF driver and the PMFW (Power Management Firmware) running on the SMU.

platform/x86: Move AMD platform drivers to separate directory

2022-06-22T09:57:55Z

Currently, AMD supported platform drivers are grouped under generic "x86" folder structure. Move the current drivers (amd-pmc and amd_hsmp) to a separate directory. This would also mean the newer driver submissions to pdx86 subsystem in the future will also land in AMD specific directory.
