2019-05-02hw/pci-host: Use object_initialize_child for correct reference countingThomas Huth
Both functions, object_initialize() and object_property_add_child() increase the reference counter of the new object, so one of the references has to be dropped afterwards to get the reference counting right. Otherwise the child object might not be properly cleaned up when the parent gets destroyed. Some functions of the pci-host devices miss to drop one of the references. Fix it by using object_initialize_child() instead, which takes care of calling object_initialize(), object_property_add_child() and object_unref() in the right order.

2019-03-18kconfig: add CONFIG_MSI_NONBROKENPaolo Bonzini
Not all interrupt controllers have a working implementation of message-signalled interrupts; in some cases, the guest may expect MSI to work but it won't due to the buggy or lacking emulation. In QEMU this is represented by the "msi_nonbroken" variable. This patch adds a new configuration symbol enabled whenever the binary contains an interrupt controller that will set "msi_nonbroken". We can then use it to remove devices that cannot be possibly added to the machine, because they require MSI. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Instead of including the same list of devices for each target, set CONFIG_PCI to true, and make the devices default to present whenever PCI is available. However, s390x does not want all the PCI devices, so there is a separate symbol to enable them. Done mostly with the following script: while read i; do i=${i%=y}; i=${i#CONFIG_} sed -i -e'/^config '$i'$/!b' -en \ -e'a\' -e' default y if PCI_DEVICES\' -e' depends on PCI' \ `grep -lw $i hw/*/Kconfig` done < default-configs/pci.mak followed by replacing a few "depends on" clauses with "select" whenever the symbol is not really related to PCI.

2019-02-05elf: Add optional function ptr to load_elf() to parse ELF notesLiam Merwick
This patch adds an optional function pointer, 'elf_note_fn', to load_elf() which causes load_elf() to additionally parse any ELF program headers of type PT_NOTE and check to see if the ELF Note is of the type specified by the 'translate_opaque' arg. If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.

2018-11-06i386: clarify that the Q35 machine type implements a P35 chipsetDaniel P. Berrangé
The 'q35' machine type implements an Intel Series 3 chipset, of which there are several variants: https://www.intel.com/Assets/PDF/datasheet/316966.pdf The key difference between the 82P35 MCH ('p35', PCI device ID 0x29c0) and 82Q35 GMCH ('q35', PCI device ID 0x29b0) variants is that the latter has an integrated graphics adapter. QEMU does not implement integrated graphics, so uses the PCI ID for the 82P35 chipset, despite calling the machine type 'q35'. Thus we rename the PCI device ID constant to reflect reality, to avoid confusing future developers. The new name more closely matches what pci.ids reports it to be: $ grep P35 /usr/share/hwdata/pci.ids | grep 29 29c0 82G33/G31/P35/P31 Express DRAM Controller 29c1 82G33/G31/P35/P31 Express PCI Express Root Port 29c4 82G33/G31/P35/P31 Express MEI Controller 29c5 82G33/G31/P35/P31 Express MEI Controller 29c6 82G33/G31/P35/P31 Express PT IDER Controller 29c7 82G33/G31/P35/P31 Express Serial KT Controller $ grep Q35 /usr/share/hwdata/pci.ids | grep 29 29b0 82Q35 Express DRAM Controller 29b1 82Q35 Express PCI Express Root Port 29b2 82Q35 Express Integrated Graphics Controller 29b3 82Q35 Express Integrated Graphics Controller 29b4 82Q35 Express MEI Controller 29b5 82Q35 Express MEI Controller 29b6 82Q35 Express PT IDER Controller 29b7 82Q35 Express Serial KT Controller Arguably the QEMU machine type should be named 'p35'.

2018-11-05hw/pci-host/x86: extend the 64-bit PCI hole relative to the fw-assigned baseLaszlo Ersek
In commit 9fa99d2519cb ("hw/pci-host: Fix x86 Host Bridges 64bit PCI hole", 2017-11-16), we meant to expose such a 64-bit PCI MMIO aperture in the ACPI DSDT that would be at least as large as the new "pci-hole64-size" property (2GB on i440fx, 32GB on q35). The goal was to offer "enough" 64-bit MMIO aperture to the guest OS for hotplug purposes. In that commit, we added or modified five functions: - pc_pci_hole64_start(): shared between i440fx and q35. Provides a default 64-bit base, which starts beyond the cold-plugged 64-bit RAM, and skips the DIMM hotplug area too (if any). - i440fx_pcihost_get_pci_hole64_start(), q35_host_get_pci_hole64_start(): board-specific 64-bit base property getters called abstractly by the ACPI generator. Both of these fall back to pc_pci_hole64_start() if the firmware didn't program any 64-bit hole (i.e. if the firmware didn't assign a 64-bit GPA to any MMIO BAR on any device). Otherwise, they honor the firmware's BAR assignments (i.e., they treat the lowest 64-bit GPA programmed by the firmware as the base address for the aperture). - i440fx_pcihost_get_pci_hole64_end(), q35_host_get_pci_hole64_end(): these intended to extend the aperture to our size recommendation, calculated relative to the base of the aperture. Despite the original intent, i440fx_pcihost_get_pci_hole64_end() and q35_host_get_pci_hole64_end() currently only extend the aperture relative to the default base (pc_pci_hole64_start()), ignoring any programming done by the firmware. This means that our size recommendation may not be met. Fix it by honoring the firmware's address assignments. The strange extension sizes were spotted by Alex, in the log of a guest kernel running on top of OVMF (which prefers to assign 64-bit GPAs to 64-bit BARs). This change only affects DSDT generation, therefore no new compat property is being introduced.

2018-09-2540p: use OR gate to wire up raven PCI interruptsMark Cave-Ayland
According to the PReP specification section 6.1.6 "System Interrupt Assignments", all PCI interrupts are routed via IRQ 15. Instead of mapping each PCI IRQ separately, we introduce an OR gate within the raven PCI host bridge and then wire the single output of the OR gate to the interrupt controller. Note that whilst the (now deprecated) PReP machine still exists we still need to preserve the old IRQ routing. This is done by adding a new "is-legacy-prep" property to the raven PCI host bridge which is set to true for the PReP machine.

2018-06-27hw/pci-host/xilinx-pcie: don't make "io" region be RAMPeter Maydell
Currently we use memory_region_init_rom_nomigrate() to create the "io" memory region to pass to pci_register_root_bus(). This is a dummy region, because this PCI controller doesn't support accesses to PCI IO space. There is no reason for the dummy region to be a RAM region; it is only used as a place where PCI BARs can be mapped, and if you could get a PCI card to do a bus master access to the IO space it should not get acts-like-RAM behaviour. Use a simple container memory region instead. (We do have one PCI card model which can do bus master accesses to IO space -- the LSI53C895A SCSI adaptor.) This avoids the oddity of having a memory region which is RAM but where the RAM is not migrated. Note that the size of the region we use here has no effect on behaviour.
