2019-07-02ppc: Introduce kvmppc_set_reg_tb_offset() helperGreg Kurz3-4/+15
Introduce a KVM helper and its stub instead of guarding the code with CONFIG_KVM. Signed-off-by: Greg Kurz <groug@kaod.org> Message-Id: <156051055736.224162.11641594431517798715.stgit@bahia.lan> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

Make xics_kvm_disconnect() able to undo the changes of a partial execution of xics_kvm_connect() and use it to perform rollback. Note that kvmppc_define_rtas_kernel_token(0) never fails, no matter the RTAS call has been defined or not.

2019-07-02xics/kvm: Always use local_err in xics_kvm_init()Greg Kurz1-6/+10
Passing both errp and &local_err to functions is a recipe for messing things up. Since we must use &local_err for icp_kvm_realize(), use &local_err everywhere where rollback must happen and have a single call to error_propagate() them all. While here, add errno to the error message.

2019-07-02spapr_pci: Fix DRC owner in spapr_dt_pci_bus()Greg Kurz1-1/+8
spapr_dt_drc() scans the aliases of all DRConnector objects and filters the ones that it will use to generate OF properties according to their owner and type. Passing bus->parent_dev _works_ if bus belongs to a PCI bridge, but it is NULL if it is the PHB's root bus. This causes all allocated PCI DRCs to be associated to all PHBs (visible in their "ibm,drc-types" properties). As a consequence, hot unplugging a PHB results in PCI devices from the other PHBs to be unplugged as well, and likely confuses the guest. Use the same logic as in add_drcs() to ensure the correct owner is passed to spapr_dt_drc().

2019-07-02xics/spapr: Detect old KVM XICS on POWER9 hostsGreg Kurz4-2/+46
Older KVMs on POWER9 don't support destroying/recreating a KVM XICS device, which is required by 'dual' interrupt controller mode. This causes QEMU to emit a warning when the guest is rebooted and to fall back on XICS emulation: qemu-system-ppc64: warning: kernel_irqchip allowed but unavailable: Error on KVM_CREATE_DEVICE for XICS: File exists If kernel irqchip is required, QEMU will thus exit when the guest is first rebooted. Failing QEMU this late may be a painful experience for the user. Detect that and exit at machine init instead.

2019-07-02xics/spapr: Register RTAS/hypercalls once at machine initGreg Kurz6-33/+3
QEMU may crash when running a spapr machine in 'dual' interrupt controller mode on some older (but not that old, eg. ubuntu 18.04.2) KVMs with partial XIVE support: qemu-system-ppc64: hw/ppc/spapr_rtas.c:411: spapr_rtas_register: Assertion `!name || !rtas_table[token].name' failed. XICS is controlled by the guest thanks to a set of RTAS calls. Depending on whether KVM XICS is used or not, the RTAS calls are handled by KVM or QEMU. In both cases, QEMU needs to expose the RTAS calls to the guest through the "rtas" node of the device tree. The spapr_rtas_register() helper takes care of all of that: it adds the RTAS call token to the "rtas" node and registers a QEMU callback to be invoked when the guest issues the RTAS call. In the KVM XICS case, QEMU registers a dummy callback that just prints an error since it isn't supposed to be invoked, ever. Historically, the XICS controller was setup during machine init and released during final teardown. This changed when the 'dual' interrupt controller mode was added to the spapr machine: in this case we need to tear the XICS down and set it up again during machine reset. The crash happens because we indeed have an incompatibility with older KVMs that forces QEMU to fallback on emulated XICS, which tries to re-registers the same RTAS calls. This could be fixed by adding proper rollback that would unregister RTAS calls on error. But since the emulated RTAS calls in QEMU can now detect when they are mistakenly called while KVM XICS is in use, it seems simpler to register them once and for all at machine init. This fixes the crash and allows to remove some now useless lines of code.

2019-07-02spapr_pci: Fix potential NULL pointer dereference in spapr_dt_pci_bus()Philippe Mathieu-Daudé1-6/+5
Commit 14e714900f6 refactored the call to spapr_dt_drc(), introducing a potential NULL pointer dereference while accessing bus->parent_dev. A trivial audit show 'bus' is not null in the two places the static function spapr_dt_drc() is called. Since the 'bus' parameter is not NULL in both callers, remove remove the test on if (bus), and add an assert() to silent static analyzers.

2019-07-02ppc/pnv: fix StoreEOI activationCédric Le Goater1-2/+1
The firmware (skiboot) of the PowerNV machines can configure the XIVE interrupt controller to activate StoreEOI on the ESB pages of the interrupts. This feature lets software do an EOI with a store instead of a load. It is not activated today on P9 for rare race condition issues but it should be on future processors. Nevertheless, QEMU has a model for StoreEOI which can be used today by experimental firmwares. But, the use of object_property_set_int() in the PnvXive model is incorrect and crashes QEMU. Replace it with a direct access to the ESB flags of the XiveSource object modeling the internal sources of the interrupt controller.

At the moment the rtas's Makefile uses generic QEMU rules which means that when QEMU is compiled on a little endian system, the spapr-rtas.bin is compiled as little endian too which is incorrect as it is always executed in big endian mode. This enforces -mbig by defining %.o:%.S rule as spapr-rtas.bin is a standalone guest binary which should not depend on QEMU flags anyway.

2019-06-26configure: use valid args testing sem_timedwaitDaniel P. Berrangé1-1/+1
The sem_timedwait function has been annotated as requiring non-null args in latest header files from GCC snapshot representing the future 2.30 release. This causes configure to fail when -Werror is used: config-temp/qemu-conf.c: In function ‘main’: config-temp/qemu-conf.c:2:25: error: null argument where non-null required (argument 1) [-Werror=nonnull] 2 | int main(void) { return sem_timedwait(0, 0); } | ^~~~~~~~~~~~~ config-temp/qemu-conf.c:2:25: error: null argument where non-null required (argument 2) [-Werror=nonnull] Signed-off-by: Daniel P.

2019-06-26configure: disallow spaces and colons in source path and build pathAntonio Ospite2-0/+9
The configure script breaks when the qemu source directory is in a path containing white spaces, in particular the list of targets is not correctly generated when calling "./configure --help" because of how the default_target_list variable is built. In addition to that, *building* qemu from a directory with spaces breaks some assumptions in the Makefiles, even if the original source path does not contain spaces like in the case of an out-of-tree build, or when symlinks are involved. To avoid these issues, refuse to run the configure script and the Makefile if there are spaces or colons in the source path or the build path, taking as inspiration what the kbuild system in linux does.

2019-06-26configure: set source_path only once and make its definition more robustAntonio Ospite1-3/+3
Since commit 79d77bcd36 (configure: Remove --source-path option, 2019-04-29) source_path cannot be overridden anymore, move it out of the "default parameters" block since the word "default" may suggest that the value can change, while in fact it does not. While at it, only set source_path once and separate the positional argument of basename with "--" to more robustly cover the case of path names starting with a dash.

2019-06-26linux-user/m68k: remove simulator syscall interfaceLaurent Vivier5-183/+1
This interface has been introduced in 2005 with the coldfire implementation (e6e5906b6e ColdFire target.) and looks like to do what the linux-user interface already does with the TRAP exception rather than the ILLEGAL exception. This interface has not been maintained since that. The semi-hosting interface is not removed so coldfire kernel with semi-hosting is always supported.

The register request via gdbstub would return the SR part which contains the Trace/Master/IRQ state flags, but would be missing the CR (Condition Register) state bits.
