This new series corresponds to the remaining patches from [1] addressing fixed memory region support for remote processor. The three remaining patches allow to: - assign a specific memory region to vdev sub device. As all virtio based services are using virtio device parent for memory allocation, I propose to keep a dedicated vdev device per virtio link for memory allocation. A second step will be to used virtio device itself. - migrate ST driver on new memory carveout management - allocate virtio rpmsg buffer from parent device Regards, Loic [1] https://lkml.org/lkml/2018/7/27/612 --- Changes from V1: - rebase on kernel v5.0-rc0 - correct error management for device registering Loic Pallardy (3): remoteproc: create vdev subdevice with specific dma memory pool remoteproc: st: add reserved memory support rpmsg: virtio: allocate buffer from parent drivers/remoteproc/remoteproc_core.c | 47 +++++++++++++++-- drivers/remoteproc/remoteproc_internal.h | 1 + drivers/remoteproc/remoteproc_virtio.c | 42 ++++++++++++++- drivers/remoteproc/st_remoteproc.c | 91 ++++++++++++++++++++++++++++---- drivers/rpmsg/virtio_rpmsg_bus.c | 6 +-- include/linux/remoteproc.h | 1 + 6 files changed, 170 insertions(+), 18 deletions(-) -- 2.7.4
