[Qemu-devel] [PATCH v4 00/10] target-arm: Parts of the AArch64 EL2/3 exception model |

Hi,
This is a second round of AArch64 EL2/3 patches working on the exception
model. Among other things adding HVC/SMC, interrupt routing to EL2/3 and
Virtual IRQs/FIQs. The VIRQ/VFIQ support only adds the external signal
delivery method.
Patch 8 fails checkpatch, seems like a bug in checkpatch, CC:d Blue.
This conflicts slightly with the PSCI emulation patches that Rob posted.
A rebase should be trivial, hooking in the PSCI emulation calls in the
HVC/SMC helpers.
Note that part of this series has already been applied, I'm only
posting the remaining patches.
Cheers,
Edgar
v3 -> v4:
* Coding style changes.
* Add access spec for v8_el3_no_el2_cp_reginfo.HCR_EL2.
* Move SCR to the el3 cpreg defs and add NO_MIGRATE to SCR_EL3.
* Correct HCR.HCD and HCR.TSC RES0 behaviour.
* Comment on hcr_write TLB flush.
* Use uint32_t with explicit masking for imm16 in syndrome generator.
* Add table lookup of interrupt masks in arm_cpu_set_irq.
* Move M profile irq handling comment from cpu-exec.c to cpu.h.
* Correct trap address for disabled HVC/SMD and for SMC routed to EL2.
v2 -> v3:
* Add more HCR bitfield macros
* Flush TLB on hcr_write change of HCR RW, DC and PTW.
* Fix hvc helper, HVC is undefined in secure mode.
* Remove uint16_t imm16 syndrome gen change.
* Replace c1_scr with scr_el3
v1 -> v2:
* Avoid imm16 mask in syndrome generation
* Use g_assert_not_reached() in arm_excp_unmasked()
* Avoid some logic duplication in arm_excp_target_el and arm_excp_unmasked.
* Put arm_excp_target_el in helper.c to start with.
* Fix SMC disable (SMD or SCD) for ARMv7 only applies if EL2 exists
* SCR_RES0_MASK -> SCR_MASK
* HCR_RES0_MASK -> HCR_MASK
* Fix SMC routing to EL2, only applies for NS EL1.
* Fix CPreg defs for ESR_EL2/3
* Fix SMC helper, SMC routing to EL2 and SCR.SMD for AArch32.
