| * hw/i386: Deprecate -drive if=scsi with PC machine typesMarkus Armbruster2017-02-211-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PC machines (pc-q35-* pc-i440fx-* pc-* isapc xenfv) automatically create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi. For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU create 25 of them. lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and currently has no maintainer in QEMU. megasas is a better choice, except with old OSes that lack drivers. virtio-scsi is a much better choice when you have a driver, but only (newish) Linux comes with one in the box. There is no good default that works for all guests. Encourage users to pick a non-obsolete SCSI HBA that works for them by deprecating -drive if=scsi.

* | test-aio-multithread: add performance comparison with thread-based mutexesPaolo Bonzini2017-02-211-0/+164
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add two implementations of the same benchmark as the previous patch, but using pthreads. One uses a normal QemuMutex, the other is Linux only and implements a fair mutex based on MCS locks and futexes. This shows that the slower performance of the 5-thread case is due to the fairness of CoMutex, rather than to coroutines. If fairness does not matter, as is the case with two threads, CoMutex can actually be faster than pthreads.

* | aio: introduce aio_co_schedule and aio_co_wakePaolo Bonzini2017-02-214-3/+334
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | aio_co_wake provides the infrastructure to start a coroutine on a "home" AioContext. It will be used by CoMutex and CoQueue, so that coroutines don't jump from one context to another when they go to sleep on a mutex or waitqueue. However, it can also be used as a more efficient alternative to one-shot bottom halves, and saves the effort of tracking which AioContext a coroutine is running on. aio_co_schedule is the part of aio_co_wake that starts a coroutine on a remove AioContext, but it is also useful to implement e.g. bdrv_set_aio_context callbacks. The implementation of aio_co_schedule is based on a lock-free multiple-producer, single-consumer queue. The multiple producers use cmpxchg to add to a LIFO stack. The consumer (a per-AioContext bottom half) grabs all items added so far, inverts the list to make it FIFO, and goes through it one item at a time until it's empty. The data structure was inspired by OSv, which uses it in the very code we'll "port" to QEMU for the thread-safe CoMutex. Most of the new code is really tests.

* | block: move AioContext, QEMUTimer, main-loop to libqemuutilPaolo Bonzini2017-02-211-5/+6
|/ | | | | | | | | | | | | | | | | | AioContext is fairly self contained, the only dependency is QEMUTimer but that in turn doesn't need anything else. So move them out of block-obj-y to avoid introducing a dependency from io/ to block-obj-y. main-loop and its dependency iohandler also need to be moved, because later in this series io/ will call iohandler_get_aio_context.

| | | | | | | | | | | | | | | | | | Peter Maydell recently ran into time-out problems with the prom-env test on a rather slow ARM board. To tackle this issue, we can speed up the test by running QEMU with "-nodefaults" for the pseries machine, so that SLOF has less devices to scan during boot, and by using the "nvramrc" environment variable instead of "boot-command", since this variable is evaluated earlier in the boot process. And to be really sure that we do not face such time out problems again, let's also increase the time out value from 100s to 120s instead.

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>

| * | trace: switch to modular code generation for sub-directoriesDaniel P. Berrange2017-01-311-1/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce rules in the top level Makefile that are able to generate trace.[ch] files in every subdirectory which has a trace-events file. The top level directory is handled specially, so instead of creating trace.h, it creates trace-root.h. This allows sub-directories to include the top level trace-root.h file, without ambiguity wrt to the trace.g file in the current sub-dir.

| | | | | | | | | | | | | | | | | | | | | | If a QIOTask has an error set and the calling code uses qio_task_propagate_error() to steal the reference to that Error object, the task would not clear its own reference. This would lead to a double-free when qio_task_free runs, if the caller had (correctly) freed the Error object they now owned. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
