If there is no such entry found, then Xen will try to map the address as a MMIO region (assuming that the Stage 1 translation table is in the direct MMIO region). If that fails as well, then there are the two following scenarios:- 1. Stage 1 translation table being in an emulated MMIO region - Xen can read the region, but it has no way to return the value read to the CPU page table walker (which tries to go through the stage1 tables to resolve the translation fault). 2. Stage 1 translation table address is invalid. In both the above scenarios, Xen will forward the abort to the guest.

If so, Xen tries to resolve the translation fault using p2m page tables. In case of data abort, Xen will try to map the mmio region to the guest (ie tries to emulate the mmio region). If the ISS is not valid and it is a data abort, then Xen tries to decode the instruction. In case of ioreq, Xen saves the decoding state, rn and imm9 to vcpu_io. Whenever the vcpu handles the ioreq successfully, it will read the decoding state to determine if the instruction decoded was a ldr/str post indexing (ie INSTR_LDR_STR_POSTINDEXING). If so, it uses these details to post increment rn. In case of mmio handler, if the mmio operation was successful, then Xen retrives the decoding state, rn and imm9. For state == INSTR_LDR_STR_POSTINDEXING, Xen will update rn. If there is an error encountered while decoding/executing the instruction, Xen will forward the abort to the guest. Also, the logic to infer the type of instruction has been moved from try_handle_mmio() to try_decode_instruction() which is called before. try_handle_mmio() is solely responsible for handling the mmio operation.

This means that when hsr_dabt.isv == 0, Xen cannot handle those instructions. This will lead to Xen to abort the guests (from which those instructions originate). With this patch, Xen is able to decode ldr/str post indexing instructions. These are a subset of instructions for which hsr_dabt.isv == 0. The following instructions are now supported by Xen :- 1. ldr x2, [x1], #8 2. ldr w2, [x1], #-4 3. ldr x2, [x1], #-8 4. ldr w2, [x1], #4 5. ldrh w2, [x1], #2 6. ldrb w2, [x1], #1 7. str x2, [x1], #8 8. str w2, [x1], #-4 9. strh w2, [x1], #2 10. strb w2, [x1], #1 In the subsequent patch, decode_arm64() will get invoked when hsr_dabt.isv == 0.
