Changes since v1: - rebased on top of PCI tree that contains Eduardo's guest_info removel series - fix ^2 times present CPU lookup when creating CPON package (spotted-by: Eduardo Habkost <ehabk...@redhat.com>)
It's mostly clean up series that removes invalid CPU entries from MADT/DSDT/SRAT tables when APIC IDs are sparse distributed*. Series also removes intermediate present CPUs bitmap in ACPI tables generation code, replacing it with machine reported presence status. That should help later for consolidating and sharing CPU hotplug codebase and extending supported CPU count above 256 on ACPI side, where I'm going to replace current "not scalable" bitmap based CPU hotplug MMIO interface with memory-hotplug like one, which could easily scale and provide additional info for ACPI CPU device objects. Tested hoptlug with: RHEL72 and WS2003. Git tree for testing: https://github.com/imammedo/qemu.git pc_madt_dsdt_lapic_cleanups_v2 * example topology with sparse APIC IDs: -smp X,sockets=2,cores=3,maxcpus=6 * it's not possible to remove notion of apic_ad_limit since guest visible interfaces like CPU hoptlug MMIO (CPON array in ACPI + corresponding MMIO in QEMU) and FWCFG should stay the same for compat reasons with current setups and legacy SeaBIOS.
