2019-11-05hw/i386: Remove obsolete LoadStateHandler::load_state_old handlersPhilippe Mathieu-Daudé
These devices implemented their load_state_old() handler 10 years ago, previous to QEMU v0.12. Since commit cc425b5ddf removed the pc-0.10 and pc-0.11 machines, we can drop this code.

2019-08-16sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

2019-06-16q35: fix mmconfig and PCI0._CRSGerd Hoffmann
This patch changes the handling of the mmconfig area. Thanks to the pci(e) expander devices we already have the logic to exclude address ranges from PCI0._CRS. We can simply add the mmconfig address range to the list get it excluded as well. With that in place we can go with a fixed pci hole which covers the whole area from the end of (low) ram to the ioapic. This will make the whole logic alot less fragile. No matter where the firmware places the mmconfig xbar, things should work correctly. The guest also gets a bit more PCI address space (seabios boot): # cat /proc/iomem [ ... ] 7ffdd000-7fffffff : reserved 80000000-afffffff : PCI Bus 0000:00 <<-- this is new b0000000-bfffffff : PCI MMCONFIG 0000 [bus 00-ff] b0000000-bfffffff : reserved c0000000-febfffff : PCI Bus 0000:00 f8000000-fbffffff : 0000:00:01.0 [ ... ] So this is a guest visible change.

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>

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'. At this point in time, however, it is not worth the churn for management applications & documentation to worry about renaming it. Signed-off-by: Daniel P.

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.

Adding the 2GB extension to that yields 8GB, which is below the firmware-programmed base of 32GB, before the patch. Therefore, before the patch, the extension is ineffective.
