This series splits the virtio rpmsg bus driver into a rpmsg bus and a virtio backend/wireformat. As we discussed the Qualcomm SMD implementation a couple of years back people suggested that I should make it "a rpmsg thingie". With the introduction of the Qualcomm 8996 platform, we must support a variant of the communication mechanism that share many of the characteristics of SMD, but are different enough that it can't be done in a single implementation. As such there is enough benefit to do the necessary work and being able to make SMD a "rpmsg thingie". On-top of this series I have patches to switch the current smd clients over to rpmsg (and by that drop the existing SMD implementation). All this allows me to implement the new backend and reuse all existing SMD drivers with the new mechanism. Changes from v1: - Split up the patch moving core code to rpmsg_core into several commits - Dropped the wrapping struct in rpmsg_core and just added the ops to the public API (but hid the implementation details) - Reordered things to reduce the size of the later patches Bjorn Andersson (17): rpmsg: Enable matching devices with drivers based on DT rpmsg: Name rpmsg devices based on channel id rpmsg: rpmsg_send() operations takes rpmsg_endpoint rpmsg: Make rpmsg_create_ept() take channel_info struct rpmsg: Clean up rpmsg device vs channel naming rpmsg: Introduce indirection table for rpmsg_device operations rpmsg: Move rpmsg_device API to new file rpmsg: Indirection table for rpmsg_endpoint operations rpmsg: Move endpoint related interface to rpmsg core rpmsg: Move helper for finding rpmsg devices to core rpmsg: Split off generic tail of create_channel() rpmsg: Split rpmsg core and virtio backend rpmsg: Hide rpmsg indirection tables rpmsg: virtio: Hide vrp pointer from the public API rpmsg: Move virtio specifics from public header rpmsg: Allow callback to return errors rpmsg: Introduce Qualcomm SMD backend drivers/remoteproc/Kconfig | 4 +- drivers/rpmsg/Kconfig | 14 + drivers/rpmsg/Makefile | 4 +- drivers/rpmsg/qcom_smd.c | 1434 +++++++++++++++++++++++++++++++++++ drivers/rpmsg/rpmsg_core.c | 498 ++++++++++++ drivers/rpmsg/rpmsg_internal.h | 82 ++ drivers/rpmsg/virtio_rpmsg_bus.c | 487 +++++------- include/linux/rpmsg.h | 246 +----- samples/rpmsg/rpmsg_client_sample.c | 14 +- 9 files changed, 2266 insertions(+), 517 deletions(-) create mode 100644 drivers/rpmsg/qcom_smd.c create mode 100644 drivers/rpmsg/rpmsg_core.c create mode 100644 drivers/rpmsg/rpmsg_internal.h -- 2.5.0 -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
