My commit log may have caused your misunderstanding. If the bit
is
not set,
the System Manager will not request doorbell interrupt. The
following
is the code from imx-sm:
if (callee) { /* Generate completion interrupt */ if ((buf->channelFlags & SMT_COMP_INT) != 0U) { status = RPC_SMT_DoorbellRing(smtChannel); } }Can the SM be updated instead ?
System Manager not only interacts with U-Boot, but also with
Linux/QNX/RTOS. System Manager cannot be changed. How come other SCMI providers (like optee) do not need this kind of change ?
Could we use a Kconfig option here, saying CONFIG_SCMI_INTR_EN? Then to i.MX95, select this Kconfig option and not break others saying optee.
There is less chance for System Manager to change. If you would like to do some change, you could do a PR, I could ask owner to give a look.
My understanding is that SCMI is supposed to be an ABI and that ABI is supposed to be the same across different platforms, correct ?
Therefore, I am wondering why does the MX95 need this special workaround, and whether that workaround should be fixed in the SCMI server OR whether other platforms need the same change as well ?
