2023-03-02hw/cxl/mailbox: Use new UUID network order define for cel_uuidIra Weiny
The cel_uuid was programatically generated previously because there was no static initializer for network order UUIDs. Use the new network order initializer for cel_uuid. Adjust cxl_initialize_mailbox() because it can't fail now. Update specification reference.

2023-03-02aspeed: Introduce a spi_boot region under the SoCCédric Le Goater
The default boot address of the Aspeed SoCs is 0x0. For this reason, the FMC flash device contents are remapped by HW on the first 256MB of the address space. In QEMU, this is currently done in the machine init with the setup of a region alias. Move this code to the SoC and introduce an extra container to prepare ground for the boot ROM region which will overlap the FMC flash remapping.

2023-03-01hw/xen: Support MSI mapping to PIRQDavid Woodhouse
The way that Xen handles MSI PIRQs is kind of awful. There is a special MSI message which targets a PIRQ. The vector in the low bits of data must be zero. The low 8 bits of the PIRQ# are in the destination ID field, the extended destination ID field is unused, and instead the high bits of the PIRQ# are in the high 32 bits of the address. Using the high bits of the address means that we can't intercept and translate these messages in kvm_send_msi(), because they won't be caught by the APIC — addresses like 0x1000fee46000 aren't in the APIC's range. So we catch them in pci_msi_trigger() instead, and deliver the event channel directly. That isn't even the worst part. The worst part is that Xen snoops on writes to devices' MSI vectors while they are *masked*. When a MSI message is written which looks like it targets a PIRQ, it remembers the device and vector for later. When the guest makes a hypercall to bind that PIRQ# (snooped from a marked MSI vector) to an event channel port, Xen *unmasks* that MSI vector on the device. Xen guests using PIRQ delivery of MSI don't ever actually unmask the MSI for themselves. Now that this is working we can finally enable XENFEAT_hvm_pirqs and let the guest use it all. Tested with passthrough igb and emulated e1000e + AHCI.
