[bugfix][6.6]Hygon: Fix S4 kernel panic issue on HYGON psp #501
Conversation
hygon inclusion category: bugfix CVE: NA --------------------------- When running the kernel which is compiled with the config CONFIG_CRYPTO_DEV_CCP_DD=y, the S4 resume process will change the TMR region, but the CSV firmware still keeps TMR region information as before. This will lead to kernel PANIC when the system resumed from S4. To address this issue, we provide PM callbacks, the callbacks will be called during S4 and resume from S4.
