Hi. I'm already experimenting with this issue, in the way of trying to get Zephyr + xAPIC good to go, besides x2APIC, but here goes the doubt in order to confirm it.
The function in the subject, which offloads work to apic_mmio_access() and then to x86_mmio_parse(), has this last one parse the instruction doing APIC mem. region access in order to intercept the access and either put or take a value to/from that memory into a register. Some MOV variants are covered there, but we are *very far* from having any reasonable coverage in that list. For instance, all the parsing code assumes the from/to places (other than the APIC mem. region) are always registers—at least that's what I understand now. What about memory regions and immediate values? Zephyr generates code using different MOVs to access the APIC mem. region and I'm filling up that list + parsing code with more info trying to capture that. Am I wrong in any point?
