When SPM-MM is enabled, I cannot use the TRNG SMC services. /* These macros are used to identify SPM-MM calls using the SMC function ID */ #define SPM_MM_FID_MASK U(0xffff) #define SPM_MM_FID_MIN_VALUE U(0x40) #define SPM_MM_FID_MAX_VALUE U(0x7f) #define is_spm_mm_fid(_fid) \ ((((_fid) & SPM_MM_FID_MASK) >= SPM_MM_FID_MIN_VALUE) && \ (((_fid) & SPM_MM_FID_MASK) <= SPM_MM_FID_MAX_VALUE)) Here, the SPM-MM SMC ID range spans from 0x40 to 0x7F, which overlaps with the TRNG SMC service IDs: /* SMC function IDs for TRNG queries */ #define ARM_TRNG_VERSION U(0x84000050) #define ARM_TRNG_FEATURES U(0x84000051) #define ARM_TRNG_GET_UUID U(0x84000052) #define ARM_TRNG_RND32 U(0x84000053) #define ARM_TRNG_RND64 U(0xC4000053) Could you please clarify the rationale behind including the TRNG SMC IDs within the SPM-MM ID range? If this overlap was unintentional, we have to fix it. Looking forward to your insights and feedback on this matter. Thanks Suresh
