Support for Incoming Message Signalling Interrupt Controller (IMSIC)
defined by the RISC-V Advanced Interrupt Architecture (AIA) specification.
This is based on early work of Himanshu Chauhan on IMSIC support for
IPI delivery. This change, however, does not include IPI delivery support,
instead it provides MSI support for peripheral devices.
IMSIC is a core-local interrupt controller with non-global interrupts,
which means that interrupt identity is effectively (hart, interrupt ID).
When IMSIC present on hart, APLIC does not trap the CPU directly,
instead it delivers the interrupt to the IMSIC instance associated with
the target hart. Upon reception of interrupt, IMSIC on hart invokes APLIC
for handling. Note that PCIe devices deliver interrupt directly to IMSIC.
Apart from IMSIC support, this includes APLIC changes:
- Obtain the interrupt trigger type from FDT and configure the interrupt
accordingly (e.g. level or edge-triggered);
- Per the AIA requirement, level-triggered MSI interrupts must be
retriggered manually after being handled. See the comment in
aplic_post_ithread();
- Reorganize APLIC register definitions to have some structure.
