rpmsg: glink: Integrate glink_ssr in qcom_glink

2020-05-07T18:04:38+00:00

In all but the very special case of a system with _only_ glink_rpm, GLINK is dependent on glink_ssr, so move it to rpmsg and combine it with qcom_glink_native in the new qcom_glink kernel module.

rpmsg: qcom_smd: Access APCS through mailbox framework

2018-04-26T00:09:57+00:00

Attempt to acquire the APCS IPC through the mailbox framework and fall back to the old syscon based approach, to allow us to move away from using the syscon. Reviewed-by: Arun Kumar Neelakantam Signed-off-by: Bjorn Andersson

rpmsg: Allow RPMSG_VIRTIO to be enabled via menuconfig or defconfig

2017-10-26T04:51:05+00:00

Currently, RPMSG_VIRTIO can only be enabled if some other kconfig option selects it. This does not allow it to be enabled for virtualized systems where Virtio RPMSG is available over Virtio MMIO or PCI transport. This patch updates RPMSG_VIRTIO kconfig option so that we can enable the VirtIO RPMSG driver via menuconfig or defconfig. The patch also removes "select RPMSG_VIRTIO" from various remoteproc kconfig options because it is now user selectable. Signed-off-by: Anup Patel Signed-off-by: Bjorn Andersson

rpmsg: glink: Introduce glink smem based transport

2017-08-30T03:33:57+00:00

The glink protocol supports different types of transports (shared memory). With the core protocol remaining the same, the way the transport's memory is probed and accessed is different. So add support for glink's smem based transports. Adding a new smem transport register function and the fifo accessors for the same.

rpmsg: glink: Move the common glink protocol implementation to glink_native.c

Move the common part of glink core protocol implementation to glink_native.c that can be shared with the smem based glink transport in the later patches. Acked-by: Arun Kumar Neelakantam Signed-off-by: Sricharan R Signed-off-by: Bjorn Andersson

rpmsg: Drop VIRTUALIZATION dependency from RPMSG_VIRTIO

2017-06-27T23:00:48+00:00

A dependency to VIRTUALIZATION has been added to RPMSG_VIRTIO (back when it was named RPMSG) in v3.10 kernel in commit 397944df3290 ("rpmsg: fix kconfig dependencies for VIRTIO") to resolve Kconfig warnings due to the inclusion of the virtio configuration file from the ARM's KVM config file. The KVM config was fixed properly in the subsequent release in commit 8bd4ffd6b3a9 ("ARM: kvm: don't include drivers/virtio/Kconfig"). So, drop this unneeded VIRTUALIZATION dependency from RPMSG_VIRTIO. Signed-off-by: Suman Anna Signed-off-by: Bjorn Andersson
