The RMM (Realm Management Monitor) provides functionality that can be accessed by SMC calls from the host. The SMC definitions are based on DEN0137[1] version 2.0-bet2 [1] https://developer.arm.com/documentation/den0137/2-0bet2/ Signed-off-by: Steven Price <[email protected]> --- Changes since v14: * Updated to RMM spec v2.0-bet2 but without the changes to move metadata out of individual address range descriptors as this is expected to be reverted in a future spec release. Changes since v13: * Updated to RMM spec v2.0-bet1 Changes since v12: * Updated to RMM spec v2.0-bet0 Changes since v9: * Corrected size of 'ripas_value' in struct rec_exit. The spec states this is an 8-bit type with padding afterwards (rather than a u64). Changes since v8: * Added RMI_PERMITTED_GICV3_HCR_BITS to define which bits the RMM permits to be modified. Changes since v6: * Renamed REC_ENTER_xxx defines to include 'FLAG' to make it obvious these are flag values. Changes since v5: * Sorted the SMC #defines by value. * Renamed SMI_RxI_CALL to SMI_RMI_CALL since the macro is only used for RMI calls. * Renamed REC_GIC_NUM_LRS to REC_MAX_GIC_NUM_LRS since the actual number of available list registers could be lower. * Provided a define for the reserved fields of FeatureRegister0. * Fix inconsistent names for padding fields. Changes since v4: * Update to point to final released RMM spec. * Minor rearrangements. Changes since v3: * Update to match RMM spec v1.0-rel0-rc1. Changes since v2: * Fix specification link. * Rename rec_entry->rec_enter to match spec. * Fix size of pmu_ovf_status to match spec. --- include/linux/arm-smccc-rmi.h | 499
