The Arm FFA specification describes a software architecture to leverages the virtualization extension to isolate software images provided by an ecosystem of vendors from each other and describes interfaces that standardize communication between the various software images including communication between images in the Secure world and Normal world. Any Hypervisor could use the FFA interfaces to enable communication between VMs it manages. The Hypervisor a.k.a Partition managers in FFA terminology can assign system resources(Memory regions, Devices, CPU cycles) to the partitions and manage isolation amongst them. This is the initial and minimal support for the FFA interface to enable communication between secure partitions and the normal world OS. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmC19HAACgkQAEG6vDF+ 4pijcw//XugK+jFEN7fA6eFzE7OeGt1xPG2mhG5TF1jtvQv2TQlij50V8evOgJmd kM3h5pUeEWMt4XrF0I2TlLOglBHLpFbU253kRPRC7zeYxK+AzD6TxtABKZ+eykAk OEQisX9FMp/h1rnnvu/OqT7l2AH/pZkVIwc2GQi6h+BvQzUq/NPanuuT+rS00U2E lLfZ98MQIjoUSDKr6r0C83gt8BlUWR62jkIkhsLycwFFouhWrdewXptfOntD4wIs 1pDRi4+qdZLbOeFCLxHR9NfMTdGdnBY//P8NwmnSYV6YnbtVcgwvwyRqMAC6ElJM Lk+AuqJS+RSCdyqQerjkvVMNSQx778nPsmzEMteOyLCAfr2kXhQ84FfqaJpFBDsJ GQUUW8H5runR2P4p2Q3Tql9tTt7AhrOuO0iUIxBu5cq4YRBPMBamtRbquJtYN+VH 9ggV4ygbkq4BIKYaBFaVffHOg0ygbvDTkXv/09wRmcGNH12y9AeuLyumhwcWxV0Z Kk0bjEieTjvisrshOeKOp5eOuhyixhFJNcffAOIos3KIkuQ1ivAL7cIig9fWF+k0 AbqOTvX4dVSdIKBi+Q8op2CZ1gyDi80P43MstTgKlbZ8AN2YWxa9S3Iw27D4gY8u tIN8PqkB2NctwQecVcGv58JyDlqTRnCcuole7fJWr3iGRdGvyV4= =DQ7A -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQJDBAABCgAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAmDI23cPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3uCcP/37GON7dD4zlic7idjGb6Wh5VuaaCSkKJDGc J7KDji52tvYVzNiqlTJu4qgTzWEIX3RLGqKHjeZHBDUwuHoWZFOTtVAU0d3xLVw1 gXa9LQypRQ094pZ4/5ClaiBV2tiQB2E8j/jppynG+8XpOUDhu5rFD+dUpOhQwqW+ REs+t1xDuGItcoweJj7ufXw+ZLgoLkbRnU7YniPQe4awS8Ml6lwDi1Rj7CXHmpW4 5AMA1FLovAZ9Y0Dyy3MVOkfHTP/LVP6LPLxcSUc6xkBT9We76WgiHPMtzvNiwSAV ZLTua2cB9OdYt1ZGB40x4XDEZs85L8dGSSRXsARkcX+ImR3rLLOcomdW5QrD7Hgr 1FtoAed13g5cxfiOizjpXLCEl6qxeW3lQ9au4FQ5xCasS7LM5tM/YuiyrafHu+Ep yVNgy35pBNjgh0NmGCGtrH7H9d/n7kdMgTNXHVkD6GW8qxXKEVfVVtwATSRJMRTV 1bjxXjA2B7u91xAnWm874X6SLVYgxRXtHUR4EMxWoSATNAL4pvTNfGz6Wwt1QD1D ZJ8wqjYKhdEnKPqjtUW7iFYrbUd550B9FXwu8f3Uaau8/ON9P+t63C1XPdmyZA57 CQMufO8TaXJ2ARDVxzO5dyYhgqN5Ew2DvDj/qmlGz26mF25JmdigeuRBplNF302+ wj3e47y6 =TfmE -----END PGP SIGNATURE----- Merge tag 'arm-ffa-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers Arm Firmware Framework for ARMv8-A(FFA) interface driver The Arm FFA specification describes a software architecture to leverages the virtualization extension to isolate software images provided by an ecosystem of vendors from each other and describes interfaces that standardize communication between the various software images including communication between images in the Secure world and Normal world.
