2017-12-05pci: Rename root bus initialization functions for clarityDavid Gibson
pci_bus_init(), pci_bus_new_inplace(), pci_bus_new() and pci_register_bus() are misleadingly named. They're not used for initializing *any* PCI bus, but only for a root PCI bus. Non-root buses - i.e. ones under a logical PCI to PCI bridge - are instead created with a direct qbus_create_inplace() (see pci_bridge_initfn()).

2017-08-02mips: Add KVM T&E segment support for TCGJames Hogan
MIPS KVM trap & emulate guest kernels have a different segment layout compared with traditional MIPS kernels, to allow both the user and kernel code to run from the user address segment without repeatedly trapping to KVM. QEMU currently supports this layout only for KVM, but its sometimes useful to be able to run these kernels in QEMU on a PC, so enable it for TCG too. This also paves the way for MIPS KVM VZ support (which uses the normal virtual memory layout) by abstracting whether user mode kernel segments are in use.

2017-08-02mips/malta: leave space for the bootmap after the initrdAurelien Jarno
Since commit 9768e2abf7 the initrd is loaded at the end of the low memory to avoid clash for the kernel relocation when kaslr is used. However this in turn conflicts with the bootmap memory that the kernel tries to place after initrd, but in low memory. The bootmap spans the whole usable physical address space. The machine can have at most 2GiB of memory, 256MiB of low memory mapped at 0x00000000, and 1792MiB of high memory mapped at 0x90000000. The biggest bootmap therefore corresponds to the adresses 0x00000000 -> 0xffffffff, which at 1 bit per 4kiB page corresponds to 128kiB in memory. Therefore reserve 128kiB after the initrd.

Emulated MIPS boards bail out with a simple "could not load kernel" when a kernel could not be load, without specifying the underlying reason. Fix that by calling load_elf_strerror. At the same time use error_report to report the error instead of fprintf.

Patch automatically created using coccinelle script: spatch --in-place -sp_file scripts/coccinelle/memory-region-init-ram.cocci -dir hw (As it turns out, there are no instances of the rom and rom_device functions that are caught by this script.)

2017-07-14memory/iommu: QOM'fy IOMMU MemoryRegionAlexey Kardashevskiy
This defines new QOM object - IOMMUMemoryRegion - with MemoryRegion as a parent. This moves IOMMU-related fields from MR to IOMMU MR. However to avoid dymanic QOM casting in fast path (address_space_translate, etc), this adds an @is_iommu boolean flag to MR and provides new helper to do simple cast to IOMMU MR - memory_region_get_iommu. The flag is set in the instance init callback. This defines memory_region_is_iommu as memory_region_get_iommu()!=NULL. This switches MemoryRegion to IOMMUMemoryRegion in most places except the ones where MemoryRegion may be an alias.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2017-05-17qdev: Replace cannot_instantiate_with_device_add_yet with !user_creatableEduardo Habkost
cannot_instantiate_with_device_add_yet was introduced by commit efec3dd631d94160288392721a5f9c39e50fb2bc to replace no_user. It was supposed to be a temporary measure. When it was introduced, we had 54 cannot_instantiate_with_device_add_yet=true lines in the code. Today (3 years later) this number has not shrunk: we now have 57 cannot_instantiate_with_device_add_yet=true lines. I think it is safe to say it is not a temporary measure, and we won't see the flag go away soon. Instead of a long field name that misleads people to believe it is temporary, replace it a shorter and less misleading field: user_creatable. Except for code comments, changes were generated using the following Coccinelle patch: @@ expression DC; @@ ( -DC->cannot_instantiate_with_device_add_yet = false; +DC->user_creatable = true; | -DC->cannot_instantiate_with_device_add_yet = true; +DC->user_creatable = false; ) @@ typedef ObjectClass; expression dc; identifier class, data; @@ static void device_class_init(ObjectClass *class, void *data) { ... dc->hotpluggable = true; +dc->user_creatable = true; ... } @@ @@ struct DeviceClass { ... -bool cannot_instantiate_with_device_add_yet; +bool user_creatable; ... } @@ expression DC; @@ ( -!DC->cannot_instantiate_with_device_add_yet +DC->user_creatable | -DC->cannot_instantiate_with_device_add_yet +!DC->user_creatable ) Cc: Alistair Francis <alistair.francis@xilinx.com> Cc: Laszlo Ersek <lersek@redhat.com> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Markus Armbruster <armbru@redhat.com> Cc: Peter Maydell <peter.maydell@linaro.org> Cc: Thomas Huth <thuth@redhat.com> Acked-by: Alistair Francis <alistair.francis@xilinx.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Marcel Apfelbaum <marcel@redhat.com> Acked-by: Marcel Apfelbaum <marcel@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Message-Id: <20170503203604.31462-2-ehabkost@redhat.com> [ehabkost: kept "TODO remove once we're there" comment] Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
2017-02-24hw/mips: MIPS Boston board supportPaul Burton
Introduce support for emulating the MIPS Boston development board. The Boston board is built around an FPGA & 3 PCIe controllers, one of which is connected to an Intel EG20T Platform Controller Hub. It is used during the development & debug of new CPUs and the software intended to run on them, and is essentially the successor to the older MIPS Malta board. This patch does not implement the EG20T, instead connecting an already supported ICH-9 AHCI controller. Whilst this isn't accurate it's enough for typical stock Boston software (eg. Linux kernels) to work with hard disks given that both the ICH-9 & EG20T implement the AHCI specification. Boston boards typically boot kernels in the FIT image format, and this patch will treat kernels provided to QEMU as such. When loading a kernel directly, the board code will generate minimal firmware much as the Malta board code does. This firmware will set up the CM, CPC & GIC register base addresses then set argument registers & jump to the kernel entry point. Alternatively, bootloader code may be loaded using the bios argument in which case no firmware will be generated & execution will proceed from the start of the boot code at the default MIPS boot exception vector (offset 0x1fc00000 into (c)kseg1). Currently real Boston boards are always used with FPGA bitfiles that include a Global Interrupt Controller (GIC), so the interrupt configuration is only defined for such cases. Therefore the board will only allow use of CPUs which implement the CPS components, including the GIC, and will otherwise exit with a message.

This reverts commit d3473e147a754e999718bf6fcb015d9978c6a1ee. This commit creates a board which defaults to having 2GB of RAM. Unfortunately on 32-bit hosts we can't create boards with 2GB of RAM, and so 'make check' fails. I missed this during testing of the merge, unfortunately.
