The total code coverage they give is: Overall coverage rate: lines......: 11.2% (59584 of 530123 lines) functions..: 15.0% (7436 of 49443 functions) branches...: 6.3% (19273 of 303933 branches) We already get pretty close to that with the machine_aarch64_virt tests which only does one full boot (~120s vs ~600s) of alpine. We expand the kernel+initrd boot (~8s) to test both GICs and also add an RNG device and a block device to generate a few IRQs and exercise the storage layer. With that we get to a coverage of: Overall coverage rate: lines......: 11.0% (58121 of 530123 lines) functions..: 14.9% (7343 of 49443 functions) branches...: 6.0% (18269 of 303933 branches) which I feel is close enough given the massive time saving.

It is described in the SMMU manual in "6.3.14 SMMU_GBPA". ABORT reset value is IMPLEMENTATION DEFINED, it is chosen to be zero(Do not abort incoming transactions). Other fields have default values of Use Incoming. If UPDATE is not set, the write is ignored. This is the only permitted behavior in SMMUv3.2 and later.(6.3.14.1 Update procedure) As this patch adds a new state to the SMMU (GBPA), it is added in a new subsection for forward migration compatibility. GBPA is only migrated if its value is different from the reset value. It does this to be backward migration compatible if SW didn't write the register.

As in, PPI0 is INTID16 .. PPI15 is INTID31. Arm's Base System Architecture specification (BSA) lists the mandated and recommended private interrupt IDs by INTID, not by PPI index. But current definitions in virt define them by PPI index, complicating cross referencing. Meanwhile, the PPI(x) macro counterintuitively adds 16 to the input value, converting a PPI index to an INTID. Resolve this by redefining the BSA-allocated PPIs by their INTIDs, and replacing the PPI(x) macro with an INTID_TO_PPI(x) one where required.

previously we treated it as "load the specified single register"). Unfortunately there is real world code out there (which shipped in at least Android 11, 12 and 13) which incorrectly uses this UNPREDICTABLE insn on the assumption that it does a single register load, which is (presumably) what it happens to do on real hardware, and is also what it does on the equivalent A32 encoding. Revert to the pre-4b222545dbf30 behaviour of not UNDEFing for this T32 encoding.

Fortunately, for us the implementation is a no-op. This feature is about interpretation of the stage 2 page table descriptor XN bits, which control execute permissions. For QEMU, the permission bits passed to an IOMMU (via MemTxAttrs and IOMMUAccessFlags) only indicate read and write; we do not distinguish data reads from instruction reads outside the CPU proper. In the SMMU architecture's terms, our interconnect between the client device and the SMMU doesn't have the ability to convey the INST attribute, and we therefore use the default value of "data" for this attribute. We also do not support the bits in the Stream Table Entry that can override the on-the-bus transaction attribute permissions (we do not set SMMU_IDR1.ATTR_PERMS_OVR=1). These two things together mean that for our implementation, it never has to deal with transactions with the INST attribute, and so it can correctly ignore the XN bits entirely. So we already implement FEAT_XNX's "XN field is now 2 bits, not 1" behaviour to the extent that we need to. Advertise the presence of the feature in SMMU_IDR3.XNX.

For the second case, because we're emulating the firmware we need to ensure that it's in the state that the firmware provides. In particular, when we reset to a lower EL than the highest one we are emulating, we need to put the CPU into a state that permits correct running at that lower EL. We already do a little of this in arm-powerctl.c (for instance we set SCR_HCE to enable the HVC insn) but we don't do enough of it. This means that in the case where we are emulating EL3 but also providing emulated PSCI the guest will crash when a secondary core tries to use a feature that needs an SCR_EL3 bit to be set, such as MTE or PAuth. The hw/arm/boot.c code also has to support this "start guest code in an EL that's lower than the highest emulated EL" case in order to do direct guest kernel booting; it has all the necessary initialization code to set the SCR_EL3 bits. Pull the relevant boot.c code out into a separate function so we can share it between there and arm-powerctl.c. This refactoring has a few code changes that look like they might be behaviour changes but aren't: * if info->secure_boot is false and info->secure_board_setup is true, then the old code would start the first CPU in Hyp mode but without changing SCR.NS and NSACR.{CP11,CP10}. This was wrong behaviour because there's no such thing as Secure Hyp mode. The new code will leave the CPU in SVC. (There is no board which sets secure_boot to false and secure_board_setup to true, so this isn't a behaviour change for any of our boards.) * we don't explicitly clear SCR.NS when arm-powerctl.c does a CPU-on to EL3. This was a no-op because CPU reset will reset to NS == 0. And some real behaviour changes: * we no longer set HCR_EL2.RW when booting into EL2: the guest can and should do that themselves before dropping into their EL1 code. (arm-powerctl and boot did this differently; I opted to use the logic from arm-powerctl, which only sets HCR_EL2.RW when it's directly starting the guest in EL1, because it's more correct, and I don't expect guests to be accidentally depending on our having set the RW bit for them.) * if we are booting a CPU into AArch32 Secure SVC then we won't set SCR.HCE any more. This affects only the vexpress-a15 and raspi2b machine types. Guests booting in this case will either: - be able to set SCR.HCE themselves as part of moving from Secure SVC into NS Hyp mode - will move from Secure SVC to NS SVC, and won't care about behaviour of the HVC insn - will stay in Secure SVC, and won't care about HVC * on an arm-powerctl CPU-on we will now set the SCR bits for pauth/mte/sve/sme/hcx/fgt features The first two of these are very minor and I don't expect guest code to trip over them, so I didn't judge it worth convoluting the code in an attempt to keep exactly the same boot.c behaviour.
