remoteproc: modify vring allocation to rely on centralized carveout allocator 2018-10-15T06:37:40+00:00 Loic Pallardy loic.pallardy@st.com 2018-07-27T13:14:47+00:00 c6aed238b7a9b15a5c90a0c31f1d36577b5d2cbe Current version of rproc_alloc_vring function supports only dynamic vring allocation. This patch allows to allocate vrings based on memory region declatation. Vrings are now manage like memory carveouts, to communize memory management code in rproc_alloc_registered_carveouts(). Allocated buffer is retrieved in rp_find_vq() thanks to rproc_find_carveout_by_name() functions for. This patch sets vrings names to vdev"x"vring"y" with x vdev index in resource table and y vring index in vdev. This will be updated when name will be associated to vdev in firmware resource table.

remoteproc: add helper function to allocate rproc_mem_entry from reserved memory 2018-10-10T05:39:14+00:00 Loic Pallardy loic.pallardy@st.com 2018-07-27T13:14:44+00:00 1429cca1175f4cb64dd5d61ffd6037895a41d672 This patch introduces rproc_res_mem_entry_init() helper function to allocate a rproc_mem_entry structure from a reserved memory region. In that case, rproc_mem_entry structure has no alloc and release ops. It will be used to assigned the specified reserved memory to any rproc sub device. Relation between rproc_mem_entry and rproc sub device will be done by name. Signed-off-by: Loic Pallardy <loic.pallardy@st.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
