Before hardware V3, hardwares do not provide the feature registers, driver resolves hardware differences based on the hardware version. As a result, the driver does not support the new hardware.

2022-08-26crypto: ccp - Fail the PSP initialization when writing psp data file failedJacky Li
Currently the OS continues the PSP initialization when there is a write failure to the init_ex_file. Therefore, the userspace would be told that SEV is properly INIT'd even though the psp data file is not updated. This is problematic because later when asked for the SEV data, the OS won't be able to provide it.

2022-08-26crypto: ccp - Initialize PSP when reading psp data file failedJacky Li
Currently the OS fails the PSP initialization when the file specified at 'init_ex_path' does not exist or has invalid content. However the SEV spec just requires users to allocate 32KB of 0xFF in the file, which can be taken care of by the OS easily. To improve the robustness during the PSP init, leverage the retry mechanism and continue the init process: Before the first INIT_EX call, if the content is invalid or missing, continue the process by feeding those contents into PSP instead of aborting. PSP will then override it with 32KB 0xFF and return SEV_RET_SECURE_DATA_INVALID status code. In the second INIT_EX call, this 32KB 0xFF content will then be fed and PSP will write the valid data to the file. In order to do this, sev_read_init_ex_file should only be called once for the first INIT_EX call. Calling it again for the second INIT_EX call will cause the invalid file content overwriting the valid 32KB 0xFF data provided by PSP in the first INIT_EX call.
