* platform/x86/amd/pmc: Use flex array when calling amd_pmc_stb_debugfs_open_v2()Shyam Sundar S K2023-10-121-13/+19
| | | | | | | | | | | | | | | | | | Currently in amd_pmc_stb_debugfs_open_v2() the buffer size is assumed to be fixed and a second call to amd_pmc_stb_debugfs_open_v2() may race with a process holding open another fd. This could change "fsize" to a bigger size causing an out of bounds read. Instead create a struct with a flexarray to solve this.

Driver is developed to support uncore frequency control (UFS) for a major and minor version. If the hardware changes major version, since offsets and definitions are changed, driver cannot continue to provide UFS interface to users. Driver can still function with minor version change as it will just miss the new functionality added by the hardware. The current implementation logs information message and skips adding uncore sysfs entry for a resource for any version mismatch. Check major and minor version mismatch for every valid resource and fail on any major version mismatch by logging an error message. A valid resource has a version which is not 0xFF.

For addition of new fields without modifying existing MMIO offsets or fields, only the minor version is changed. Driver is developed to support SST functionality for a major and minor version. If the hardware changes major version, since offsets and definitions are changed, driver cannot continue to provide SST interface to users. Driver can still function with a minor version change as it will just miss the new functionality added by the hardware. The current implementation doesn't ignore any version change. If there is mismatch with the minor version, continue with an information log message. If there is mismatch with the major version, log error and exit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allowed level mask is a mask of levels, which are currently allowed to dynamically switch by the OS. Fused mask is a mask of all levels even if OS is not allowed to switch. Even if OS is not allowed to dynamically switch, it is still possible for user to boot to a level by using BIOS option. To decide which level to boot next time, user wants to check parameters (power, performance or thermal) of that level to decide. So, when passing the level mask for display to user space, use fuse enabled mask, which has all levels.
