Revert "remoteproc: Merge table_ptr and cached_table pointers"

2016-12-30T11:26:31Z

Following any fw_rsc_vdev entries in the resource table are two variable length arrays, the first one reference vring resources and the second one is the virtio config space. The virtio config space is used by virtio to communicate status and configuration changes and must as such be shared with the remote. The reverted commit incorrectly made any changes to the virtio config space only affect the local copy, in an attempt to allowing memory protection of the shared resource table. This reverts commit cda8529346935fc86f476999ac4fbfe4e17abf11. Signed-off-by: Bjorn Andersson

remoteproc: Merge table_ptr and cached_table pointers

2016-11-15T05:52:18Z

As all vdev resources are allocated before we boot the remote processor we no longer need to support modifying the resource table while the remote is running. This saves us from the table_ptr dance, but more importantly allow the remote processor to enable security lock down of the loaded table memory region. Signed-off-by: Bjorn Andersson

remoteproc: Decouple vdev resources and devices

2016-11-15T05:52:17Z

Represent the virtio device part of the vdev resources as remoteproc subdevices to finalize the decoupling of the virtio resource and device handling. Signed-off-by: Bjorn Andersson

remoteproc: Assign kref to rproc_vdev

remoteproc: Introduce subdevices

2016-11-10T05:17:08Z

A subdevice is an abstract entity that can be used to tie actions to the booting and shutting down of a remote processor. The subdevice object is expected to be embedded in concrete implementations, allowing for a variety of use cases to be implemented. Signed-off-by: Bjorn Andersson

remoteproc: Keep local copy of firmware name

2016-10-18T22:03:35Z

Storage of the firmware name was inconsistent, either storing a pointer to a name stored with unknown ownership, or a variable length tacked onto the end of the struct proc allocated in rproc_alloc. In preparation for allowing the firmware of an already allocated struct rproc to be changed, instead always keep a locally maintained copy of the firmware name.

remoteproc: Split driver and consumer dereferencing

2016-10-03T05:50:21Z

In order to be able to lock a rproc driver implementations only when used by a client, we must differ between the dereference operation of a client and the implementation itself. This patch brings no functional change. Signed-off-by: Bjorn Andersson

remoteproc: core: transform struct fw_rsc_vdev_vring reserved field in pa

2016-09-06T18:06:40Z

In current implementation, struct fw_rsc_vdev_vring which describes vring resource in firmware resource table owns only device address, because it assumes that host is responsible of vring allocation and only device address is needed by coprocessor. But if vrings need to be fixed in system memory map for any reasons (security, SoC charactieristics...), physical address is needed exatly identified the memory chunck by host. For that let's transform reserved field of struct fw_rsc_vdev_vring to pa (physical address). Signed-off-by: Loic Pallardy Signed-off-by: Bjorn Andersson

remoteproc: Move handling of cached table to boot/shutdown

2016-08-18T06:20:51Z

As we moved the vdev handling to the main boot/shutdown code path we can further simplify the resource table handling by moving the parsing spet to boot as well. The lifespan of the resource table is changed to live from rproc_boot() to rproc_shutdown(). Cc: Lee Jones Cc: Loic Pallardy Signed-off-by: Bjorn Andersson
