We are using multiple scmi instances within a VM. We are sharing the same smc-id(func_id) with all scmi instance. The hypervisor needs a way to distinguish among hvc calls made from different instances. This patch series introduces new compatible string which can be used to pass shmem channel address as parameters to smc/hvc calls. --- v4 -> split shmem address into 4KB-pages and offset v3 -> pass shmem channel address as parameter v2 -> fix the compilation erros on 32bit platform(see below) Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202304100606.kUjhsRYf-lkp@intel.com/ v1 -> original patches Nikunj Kela (2): dt-bindings: firmware: arm,scmi: support for parameter in smc/hvc call firmware: arm_scmi: Augment SMC/HVC to allow optional parameters .../devicetree/bindings/firmware/arm,scmi.yaml | 8 +++++++- drivers/firmware/arm_scmi/driver.c | 1 + drivers/firmware/arm_scmi/smc.c | 14 +++++++++++++- 3 files changed, 21 insertions(+), 2 deletions(-)
