rpmsg: glink-smem: Name the edge based on parent remoteproc

2019-09-17T22:33:31Z

Naming the glink edge device on the parent of_node short name causes collisions when multiple remoteproc instances with only different unit address are described on the platform_bus in DeviceTree. Base the edge's name on the parent remoteproc's name instead, to ensure that it's unique. Reviewed-by: Niklas Cassel Signed-off-by: Bjorn Andersson

rpmsg: glink: Use struct_size() helper

2019-08-29T18:24:31Z

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct { ... struct intent_pair intents[]; } __packed * msg; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*msg) + sizeof(struct intent_pair) * count with: struct_size(msg, intents, count) This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A.

rpmsg: virtio_rpmsg_bus: replace "%p" with "%pK"

2019-08-27T22:21:05Z

The virtio_rpmsg_bus driver uses the "%p" format-specifier for printing the vring buffer address. This prints only a hashed pointer even for previliged users. Use "%pK" instead so that the address can be printed during debug using kptr_restrict sysctl. Signed-off-by: Suman Anna Signed-off-by: Bjorn Andersson

rpmsg: core: Make remove handler for rpmsg driver optional.

2019-05-22T06:54:06Z

Most other bus (for example, SPI, i2c) have the remove handler for driver optional. Make remove handler for rpmsg driver optional too. Signed-off-by: Pi-Hsun Shih Signed-off-by: Bjorn Andersson

rpmsg: virtio: allocate buffer from parent

2019-02-21T05:15:49Z

Remoteproc is now capable to create one specific sub-device per virtio link to associate a dedicated memory pool. This implies to change device used by virtio_rpmsg for buffer allocation from grand-parent to parent.

rpmsg: glink: smem: Support rx peak for size less than 4 bytes

2018-10-04T00:04:32Z

The current rx peak function fails to read the data if size is less than 4bytes. Use memcpy_fromio to support data reads of size less than 4 bytes.

rpmsg: smd: fix memory leak on channel create

2018-09-28T03:11:11Z

Currently a failed allocation of channel->name leads to an immediate return without freeing channel. Fix this by setting ret to -ENOMEM and jumping to an exit path that kfree's channel.

rpmsg: glink: Remove chunk size word align warning

2018-09-01T21:00:43Z

It is possible for the chunk sizes coming from the non RPM remote procs to not be word aligned. Remove the alignment warning and continue to read from the FIFO so execution is not stalled. Signed-off-by: Chris Lew Signed-off-by: Arun Kumar Neelakantam Signed-off-by: Bjorn Andersson
