There is also a patch introducing the use of the "bit 15" convention from the FF-A specification to distinguish between secure and non-secure identifiers as Xen VM IDs cannot have bit 15 set. Finally we introduce support for indirect messages and for that we transmit the RXTX buffers to the SPMC and we put the message related functions into their own source file. Changes in v2: - do not activate FF-A if firmware does not support i - various clean up and small fixes explained in each patch - rebase on top of latest staging Bertrand Marquis (10): xen/arm: ffa: Rework firmware discovery xen/arm: ffa: Rework feature discovery xen/arm: ffa: Fix version negotiation xen/arm: ffa: Fine granular call support xen/arm: ffa: Rework partition info get xen/arm: ffa: Use bit 15 convention for SPs xen/arm: ffa: Transmit RXTX buffers to the SPMC xen/arm: ffa: move message function into ffa_msg.c xen/arm: ffa: Remove per VM notif_enabled xen/arm: ffa: Add indirect message support xen/arch/arm/tee/Makefile | 1 + xen/arch/arm/tee/ffa.c | 251 +++++++++++++++----------------- xen/arch/arm/tee/ffa_msg.c | 129 ++++++++++++++++ xen/arch/arm/tee/ffa_notif.c | 17 +-- xen/arch/arm/tee/ffa_partinfo.c | 230 ++++++++++++++++++++--------- xen/arch/arm/tee/ffa_private.h | 79 ++++++++-- xen/arch/arm/tee/ffa_rxtx.c | 162 +++++++++++++++++---- xen/arch/arm/tee/ffa_shm.c | 39 +++-- 8 files changed, 642 insertions(+), 266 deletions(-) create mode 100644 xen/arch/arm/tee/ffa_msg.c
