2017-09-19cpu: make cpu_generic_init() abort QEMU on errorIgor Mammedov
Almost every user of cpu_generic_init() checks for returned NULL and then reports failure in a custom way and aborts process. Some users assume that call can't fail and don't check for failure, though they should have checked for it. In either cases cpu_generic_init() failure is fatal, so instead of checking for failure and reporting it various ways, make cpu_generic_init() report errors in consistent way and terminate QEMU on failure.

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.

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.

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 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.

2017-02-21hw: Drop superfluous special checks for orphaned -driveMarkus Armbruster
We've traditionally rejected orphans here and there, but not systematically. For instance, the sun4m machines have an onboard SCSI HBA (bus=0), and have always rejected bus>0. Other machines with an onboard SCSI HBA don't. Commit a66c9dc made all orphans trigger a warning, and the previous commit turned this into an error. The checks "here and there" are now redundant. Drop them. Note that the one in mips_jazz.c was wrong: it rejected bus > MAX_FD, but MAX_FD is the number of floppy drives per bus. Error messages change from $ qemu-system-x86_64 -drive if=ide,bus=2 qemu-system-x86_64: Too many IDE buses defined (3 > 2) $ qemu-system-mips64 -M magnum,accel=qtest -drive if=floppy,bus=2,id=fd1 qemu: too many floppy drives $ qemu-system-sparc -M LX -drive if=scsi,bus=1 qemu: too many SCSI bus to $ qemu-system-x86_64 -drive if=ide,bus=2 qemu-system-x86_64: -drive if=ide,bus=2: machine type does not support if=ide,bus=2,unit=0 $ qemu-system-mips64 -M magnum,accel=qtest -drive if=floppy,bus=2,id=fd1 qemu-system-mips64: -drive if=floppy,bus=2,id=fd1: machine type does not support if=floppy,bus=2,unit=0 $ qemu-system-sparc -M LX -drive if=scsi,bus=1 qemu-system-sparc: -drive if=scsi,bus=1: machine type does not support if=scsi,bus=1,unit=0 Cc: John Snow <jsnow@redhat.com> Cc: "Hervé Poussineau" <hpoussin@reactos.org> Cc: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <1487153147-11530-9-git-send-email-armbru@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com>
2017-02-21hw: Default -drive to if=ide explicitly where it worksMarkus Armbruster
Block backends defined with -drive if=ide are meant to be picked up by machine initialization code: a suitable frontend gets created and wired up automatically. if=ide drives not picked up that way can still be used with -device as if they had if=none, but that's unclean and best avoided. Unused ones produce an "Orphaned drive without device" warning. -drive parameter "if" is optional, and the default depends on the machine type. If a machine type doesn't specify a default, the default is "ide". Many machine types default to if=ide, even though they don't actually have an IDE controller. A future patch will change these defaults to something more sensible. To prepare for it, this patch makes default "ide" explicit for the machines that actually pick up if=ide drives: * alpha: clipper * arm/aarch64: spitz borzoi terrier tosa * i386/x86_64: generic-pc-machine (with concrete subtypes pc-q35-* pc-i440fx-* pc-* isapc xenfv) * mips64el: fulong2e * mips/mipsel/mips64el: malta mips * ppc/ppc64: mac99 g3beige prep * sh4/sh4eb: r2d * sparc64: sun4u sun4v Note that ppc64 machine powernv already sets an "ide" default explicitly. Its IDE controller isn't implemented, yet.

The CharDriverState.init() callback was introduced in commit ceecf1d158. It is only called from text_console_do_init(), but it is no longer set since commit a61ae7f88 (init assignment has been removed by accident). It seems correct to use an event callback instead and print the console text on CHR_EVENT_OPENED. That way we can remove the single user of CharDriverState init().

2016-07-28hw/mips_malta: Fix YAMON API print routinePaul Burton
The print routine provided as part of the in-built bootloader had a bug in that it attempted to use a jump instruction as part of a loop, but the target has its upper bits zeroed leading to control flow transferring to 0xb0000814 rather than the intended 0xbfc00814. Fix this by using a branch instruction instead, which seems more fit for purpose. A simple way to test this is to build a Linux kernel with EVA enabled & attempt to boot it in QEMU. It will attempt to print a message indicating the configuration mismatch but QEMU would previously incorrectly jump & wind up printing a continuous stream of the letter E.
