18c250bd - firmware: arm_ffa: Split bus and driver into distinct modules

Wed, 15 May 2024 09:40:28 +0000

firmware: arm_ffa: Split bus and driver into distinct modulesMake the FF-A bus on its own as a distinct module initialized atsubsys_initcall level when builtin.Keep the FF-A driver core stack, together with any configured transport,in a different module initialized as module_init level.FF-A drivers initialization is now changed to module_init level.Acked-by: Sebastian Ene Link: https://lore.kernel.org/r/20240515094028.1947976-2-sudeep.holla@arm.comSigned-off-by: Sudeep Holla List of files: /linux-6.15/drivers/firmware/arm_ffa/Makefile

714be77e - firmware: arm_ffa: Add support for SMCCC as transport to FFA driver

Fri, 21 May 2021 15:10:31 +0000

firmware: arm_ffa: Add support for SMCCC as transport to FFA driverThere are requests to keep the transport separate in order to allowother possible transports like virtio. So let us keep the SMCCC transportspecific routines abstracted.It is kept simple for now. Once we add another transport, we can developbetter abstraction.Link: https://lore.kernel.org/r/20210521151033.181846-4-sudeep.holla@arm.comTested-by: Jens Wiklander Reviewed-by: Jens Wiklander Signed-off-by: Sudeep Holla List of files: /linux-6.15/drivers/firmware/arm_ffa/Makefile

3bbfe987 - firmware: arm_ffa: Add initial Arm FFA driver support

Fri, 21 May 2021 15:10:30 +0000

firmware: arm_ffa: Add initial Arm FFA driver supportThis just add a basic driver that sets up the transport(e.g. SMCCC),checks the FFA version implemented, get the partition ID for self andsets up the Tx/Rx buffers for communication.Link: https://lore.kernel.org/r/20210521151033.181846-3-sudeep.holla@arm.comTested-by: Jens Wiklander Signed-off-by: Sudeep Holla List of files: /linux-6.15/drivers/firmware/arm_ffa/Makefile

e7818584 - firmware: arm_ffa: Add initial FFA bus support for device enumeration

Fri, 21 May 2021 15:10:29 +0000

firmware: arm_ffa: Add initial FFA bus support for device enumerationThe Arm FF for Armv8-A specification has concept of endpoints orpartitions. In the Normal world, a partition could be a VM whenthe Virtualization extension is enabled or the kernel itself.In order to handle multiple partitions, we can create a FFA device foreach such partition on a dedicated FFA bus. Similarly, different driversrequiring FFA transport can be registered on the same bus. We can matchthe device and drivers using UUID. This is mostly for the in-kernelusers with FFA drivers.Link: https://lore.kernel.org/r/20210521151033.181846-2-sudeep.holla@arm.comTested-by: Jens Wiklander Signed-off-by: Sudeep Holla List of files: /linux-6.15/drivers/firmware/arm_ffa/Makefile
