2017-02-07wdt: Add Aspeed watchdog device modelCédric Le Goater1-0/+32
The Aspeed SoC includes a set of watchdog timers using 32-bit decrement counters, which can be based either on the APB clock or a 1 MHz clock. The watchdog timer is designed to prevent system deadlock and, in general, it should be restarted before timeout. When a timeout occurs, different types of signals can be generated, ARM reset, SOC reset, System reset, CPU Interrupt, external signal or boot from alternate block. The current model only performs the system reset function as this is used by U-Boot and Linux.

2017-02-06migration: Check for ID lengthDr. David Alan Gilbert1-0/+2
The qdev id of a device can be huge if it's on the end of a chain of bridges; in reality such chains shouldn't occur but they can be made to by chaining PCIe bridges together. The migration format has a number of 256 character long format limits; check we don't hit them (we already use pstrcat/cpy but that just protects us from buffer overruns, we fairly quickly hit an assert).

into staging ppc patch queue 2017-02-02 This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug. This is a long overdue ppc pull request for qemu-2.9. It's been a long time coming due to some holidays and inconveniently timed problems with testing. So, there's a lot in here: * More POWER9 instruction implementations for TCG * The simpler parts of my CPU compatibility mode cleanup * This changes behaviour to prefer compatibility modes over "raW" mode for new machine type versions * New "40p" machine type which is essentially a modernized and cleaned up "prep". The intention is that it will replace "prep" once it has some more testing and polish. * Add pseries-2.9 machine type * Implement H_SIGNAL_SYS_RESET hypercall * Consolidate the two alternate CPU init paths in pseries by making it always go through CPU core objects to initialize CPU * A number of bugfixes and cleanups * Stop the guest timebase when the guest is stopped under KVM. This makes the guest system clock also stop when paused, which matches the x86 behaviour. * Some preliminary cleanups leading towards implementation of the POWER9 MMU. There are also some changes not strictly related to ppc code, but for its benefit: * Limit the pxi-expander-bridge (PXB) device to x86 guests only (it's essentially a hack to work around historical x86 limitations) * Some additions to the 128-bit math in host_utils, necessary for some of the new instructions. * Revise a number of qtests and enable them for ppc # gpg: Signature made Thu 02 Feb 2017 01:40:16 GMT # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.9-20170202: (107 commits) hw/ppc/pnv: Use error_report instead of hw_error if a ROM file can't be found ppc/kvm: Handle the "family" CPU via alias instead of registering new types target/ppc/mmu_hash64: Fix incorrect shift value in amr calculation target/ppc/mmu_hash64: Fix printing unsigned as signed int tcg/POWER9: NOOP the cp_abort instruction target/ppc/debug: Print LPCR register value if register exists target-ppc: Add xststdc[sp, dp, qp] instructions target-ppc: Add xvtstdc[sp,dp] instructions target-ppc: Add MMU model check for booke machines ppc: switch to constants within BUILD_BUG_ON target/ppc/cpu-models: Fix/remove bad CPU aliases target/ppc: Remove unused POWERPC_FAMILY(POWER) spapr: clock should count only if vm is running ppc: Remove unused function cpu_ppc601_rtc_init() target/ppc: Add pcr_supported to POWER9 cpu class definition powerpc/cpu-models: rename ISAv3.00 logical PVR definition target-ppc: Add xvcv[hpsp, sphp] instructions target-ppc: Add xsmulqp instruction target-ppc: Add xsdivqp instruction target-ppc: Add xscvsdqp and xscvudqp instructions ... # Conflicts: # hw/pci-bridge/Makefile.objs Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

msix_init() reports errors with error_report(), which is wrong when it's used in realize(). The same issue was fixed for msi_init() in commit 1108b2f. In order to make the API change as small as possible, leave the return value check to later patch.

2017-01-31hw/ppc/spapr: Fix boot path of usb-host storage devicesThomas Huth1-0/+1
When passing through an USB storage device to a pseries guest, it is currently not possible to automatically boot from the device if the "bootindex" property has been specified, too (e.g. when using "-device nec-usb-xhci -device usb-host,hostbus=1,hostaddr=2,bootindex=0" at the command line). The problem is that QEMU builds a device tree path like "/pci@800000020000000/usb@0/usb-host@1" and passes it to SLOF in the /chosen/qemu,boot-list property. SLOF, however, probes the USB device, recognizes that it is a storage device and thus changes its name to "storage", and additionally adds a child node for the SCSI LUN, so the correct boot path in SLOF is something like "/pci@800000020000000/usb@0/storage@1/disk@101000000000000" instead. So when we detect an USB mass storage device with SCSI interface, we've got to adjust the firmware boot-device path properly that SLOF can automatically boot from the device.

spapr_h_cas_compose_response() includes a cpu_update parameter which controls whether it includes updated information on the CPUs in the device tree fragment returned from the ibm,client-architecture-support (CAS) call. Providing the updated information is essential when CAS has negotiated compatibility options which require different cpu information to be presented to the guest. However, it should be safe to provide in other cases (it will just override the existing data in the device tree with identical data). This simplifies the code by removing the parameter and always providing the cpu update information.

2017-01-31pseries: Always use core objects for CPU constructionDavid Gibson1-1/+0
Currently the pseries machine has two paths for constructing CPUs. On newer machine type versions, which support cpu hotplug, it constructs cpu core objects, which in turn construct CPU threads. For older machine versions it individually constructs the CPU threads. This division is going to make some future changes to the cpu construction harder, so this patch unifies them. Now cpu core objects are always created. This requires some updates to allow core objects to be created without a full complement of threads (since older versions allowed a number of cpus not a multiple of the threads-per-core). Likewise it needs some changes to the cpu core hot/cold plug path so as not to choke on the old machine types without hotplug support. For good measure, we move the cpu construction to its own subfunction, spapr_init_cpus(). Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Greg Kurz <groug@kaod.org>

2017-01-27xen-platform: add missing disk unplug optionPaul Durrant1-1/+1
The Xen HVM unplug protocol [1] specifies a mechanism to allow guests to request unplug of 'aux' disks (which is stated to mean all IDE disks, except the primary master). This patch adds support for that unplug request. NOTE: The semantics of what happens if unplug of all disks and 'aux' disks is simultaneously requests is not clear. The patch makes that assumption that an 'all' request overrides an 'aux' request.

2017-01-27chardev: qom-ifyMarc-André Lureau2-49/+60
Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

2017-01-27char: allocate CharDriverState as a single objectMarc-André Lureau1-1/+1
Use a single allocation for CharDriverState, this avoids extra allocations & pointers, and is a step towards more object-oriented CharDriver. Gtk console is a bit peculiar, gd_vc_chr_set_echo() used to have a temporary VirtualConsole to save the echo bit. Instead now, we consider whether vcd->console is set or not, and restore the echo bit saved in VCDriverState when calling gd_vc_vte_init(). The casts added are temporary, they are replaced with QOM type-safe macros in a later patch in this series.

2017-01-27block: Fix target variable of BLKSECTGET ioctlEric Farman1-0/+1
Commit 6f6071745bd0 ("raw-posix: Fetch max sectors for host block device") introduced a routine to call the kernel BLKSECTGET ioctl, which stores the result back to user space. However, the size of the data returned depends on the routine handling the ioctl. The (compat_)blkdev_ioctl returns a short, while sg_ioctl returns an int. Thus, on big-endian systems, we can find ourselves accidentally shifting the result to a much larger value. (On s390x, a short is 16 bits while an int is 32 bits.) Also, the two ioctl handlers return values in different scales (block returns sectors, while sg returns bytes), so some tweaking of the outputs is required such that hdev_get_max_transfer_length returns a value in a consistent set of units.
