Issue is that struct virtio_dev is not correctly reinitialized like done at initial allocation thanks to kzalloc() and kobject is considered as already initialized by kernel. That is due to the fact struct virtio_dev is allocated and released at vdev resource handling level managed and virtio device is registered and unregistered at rproc subdevices level. Moreover kernel documentation mentions that device struct must be zero initialized before calling device_initialize(). This patch disentangles struct virtio_dev from struct rproc_vdev as the two struct don't have the same life-cycle. struct virtio_dev is now allocated on rproc_start() and released on rproc_stop().

This patch introduces an alloc ops in rproc_mem_entry structure to associate dedicated allocation mechanism to each memory entry descriptor in order to do remote core agnostic from memory allocators. The introduction of this ops allows to perform allocation of all registered carveout at the same time, just before calling rproc_start(). It simplifies and makes uniform carveout management whatever origin. Signed-off-by: Loic Pallardy <loic.pallardy@st.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
* remoteproc: introduce rproc_find_carveout_by_name functionLoic Pallardy2018-10-091-0/+42
| | | | | | | | | | This patch provides a new function to find a carveout according to a name. If match found, this function returns a pointer on the corresponding carveout (rproc_mem_entry structure).

* remoteproc: add release ops in rproc_mem_entry structLoic Pallardy2018-10-091-2/+21
| | | | | | | | | | | | Memory entry could be allocated in different ways (ioremap, dma_alloc_coherent, internal RAM allocator...). This patch introduces a release ops in rproc_mem_entry structure to associate dedicated release mechanism to each memory entry descriptor in order to keep remoteproc core generic.
