Somlo, Anthony Liguori As reported in http://article.gmane.org/gmane.comp.emulators.qemu/253987 Mac OSX actually requires describing all occupied slots in ACPI - even if hotplug isn't enabled. I didn't expect this so I dropped description of all non hotpluggable slots from ACPI. As a result: before commit 99fd437dee468609de8218f0eb3b16621fb6a9c9 (enable hotplug for pci bridges), PCI cards show up in the "device tree" of OS X (System Information). E.g., on MountainLion users have: Hardware -> PCI Cards: Card Type Driver Installed Slot *ethernet Ethernet Controller Yes PCI Slot 2 pci8086,2934 USB UHC Yes PCI Slot 29 ethernet: Type: Ethernet Controller Driver Installed: Yes MSI: No Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Slot PCI Slot 2 Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/... Version: 3.1.1b1 After commit 99fd437dee468609de8218f0eb3b16621fb6a9c9, users get: Hardware -> PCI Cards: This computer doesn't contain any PCI cards. If you installed PCI cards, make sure they're properly installed. Hardware -> Ethernet Cards ethernet: Type: Ethernet Controller Bus: PCI Vendor ID: 0x8086 Device ID: 0x100e Subsystem Vendor ID: 0x1af4 Subsystem ID: 0x1100 Revision ID: 0x0003 BSD name: en0 Kext name: AppleIntel8254XEthernet.kext Location: /System/Library/Extensions/... Version: 3.1.1b1 Ethernet still works, but it's not showing up on the PCI bus, and it no longer thinks it's plugged in to slot #2, as it used to before the change. To fix, append description for all occupied non hotpluggable PCI slots. One need to be careful when doing this: VGA and ISA device were already described, so we need to drop description from DSDT.

Tsirkin @ 2014-02-17 14:25 UTC (permalink / raw) To: qemu-devel; +Cc: Peter Maydell, Jan Kiszka, Anthony Liguori, Igor Mammedov From: Igor Mammedov <imammedo@redhat.com> Windows XP shows COM2 port as non functional in "Device Manager" although no COM2 port backing device is present in QEMU. This regression is really due to 3bb28b7208b349e7a1b326e3c6ef9efac1d462bf? memory: Provide separate handling of unassigned io ports accesses That is caused by the fact that QEMU reports to OSPM that device is present by setting 5th bit in PII4XPM.pci_conf[0x67] register when COM2 doesn't exist. It happens due to memory_region_present(io_as, 0x2f8) returning false positive since 0x2f8 address eventually translates into catchall io_as address space. Fix memory_region_present(parent, addr) by returning true only if addr maps into a MemoryRegion within parent (excluding parent itself), to match its doc comment. While at it fix copy/paste error in memory_region_present() doc comment. Note: this is a temporary hack: we really need better handling for unassigned regions, we should avoid fallback regions since they are bad for performance (breaking radix tree assumption that the data structure is sparsely populated); for memory we need to fix this to implement PCI master abort properly, anyway.
