2018-02-19trace: avoid SystemTap "char const" warningsStefan Hajnoczi
SystemTap's dtrace(1) produces the following warning when it encounters "char const" instead of "const char": Warning: /usr/bin/dtrace:trace-dtrace-root.dtrace:66: syntax error near: probe flatview_destroy_rcu Warning: Proceeding as if --no-pyparsing was given. This is a limitation in current SystemTap releases. I have sent a patch upstream to accept "char const" since it is valid C: https://sourceware.org/ml/systemtap/2018-q1/msg00017.html In QEMU we still wish to avoid warnings in the current SystemTap release. It's simple enough to replace "char const" with "const char". I'm not changing the documentation or implementing checks to prevent this from occurring again in the future. The next release of SystemTap will hopefully resolve this issue. Cc: Daniel P. Berrange <berrange@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Daniel P.

2018-02-19tracetool: Update argument format regex to non-greedy starJon Emil Jahren
Using the greedy star matching, arguments like "...%"PRIx64 caused issues for functions with multiple PRI formats. The issue was only seen with the ust backend, as it is the only one using the format regex. The result for many functions was that the arguments coming after the greedy star end was left out of the tracepoint, and in some cases some of the arguments that was traced had the wrong format.

2018-02-19hw/rdma: Implementation of PVRDMA deviceYuval Shaia
PVRDMA is the QEMU implementation of VMware's paravirtualized RDMA device. It works with its Linux Kernel driver AS IS, no need for any special guest modifications. While it complies with the VMware device, it can also communicate with bare metal RDMA-enabled machines and does not require an RDMA HCA in the host, it can work with Soft-RoCE (rxe). It does not require the whole guest RAM to be pinned allowing memory over-commit and, even if not implemented yet, migration support will be possible with some HW assistance. Implementation is divided into 2 components, rdma general and pvRDMA specific functions and structures. The second PVRDMA sub-module - interaction with PCI layer. - Device configuration and setup (MSIX, BARs etc). - Setup of DSR (Device Shared Resources) - Setup of device ring. - Device management.

2018-02-19mem: add share parameter to memory-backend-ramMarcel Apfelbaum
Currently only file backed memory backend can be created with a "share" flag in order to allow sharing guest RAM with other processes in the host. Add the "share" flag also to RAM Memory Backend in order to allow remapping parts of the guest RAM to different host virtual addresses. This is needed by the RDMA devices in order to remap non-contiguous QEMU virtual addresses to a contiguous virtual address range. Moved the "share" flag to the Host Memory base class, modified phys_mem_alloc to include the new parameter and a new interface memory_region_init_ram_shared_nomigrate. There are no functional changes if the new flag is not used. Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Marcel Apfelbaum <marcel@redhat.com>

For very large framebuffers, it is theoretically possible for the result of 'vs->throttle_output_offset * VNC_THROTTLE_OUTPUT_LIMIT_SCALE' to exceed the size of a 32-bit int. For this to happen in practice, the video RAM would have to be set to a large enough value, which is not likely today.

Having analyzed the coredump, I understood that the reason is that ioc_tag is reset on vnc_disconnect_start and ioc is cleaned in vnc_disconnect_finish. Between these two events due to some reasons the ioc_tag was set again and after vnc_disconnect_finish the handler is running with freed ioc, which led to the segmentation fault.

2018-02-16tests/boot-serial-test: Fix problem with timeout due to dropped charactersThomas Huth
Commit 92b540dac9fc3a5 introduce a counter to handle the timeouts in a better way. But in case ccnt reaches 512, the current read character is ignored - and if that character is part of the string that we are looking for, the test fails to match the string. Almost all of the tests look for a string within the first 512 bytes of firmware output, so the problem never triggered there. But the hppa test that has been added recently looks for a longer string at the very end of a long output, thus there's a chance that we miss a character there so that the test fails unexpectedly. Fix it by *not* reading and dropping a character if the counter reaches 512.

2018-02-16ppc/spapr-caps: Disallow setting workaround for spapr-cap-ibsSuraj Jitindar Singh
The spapr-cap cap-ibs can only have values broken or fixed as there is no explicit workaround required. Currently setting the value workaround for this cap will hit an assert if the guest makes the hcall h_get_cpu_characteristics. Report an error when attempting to apply the setting with a more helpful error message.

A couple of notes: - removed ctx->nip in favour of base->pc_next. Yes, it is annoying, but didn't want to waste its 4 bytes. - ctx->singlestep_enabled does a lot more than base.singlestep_enabled; this confused me at first.

2018-02-16spapr: consolidate the VCPU id numbering logic in a single placeGreg Kurz
Several places in the code need to calculate a VCPU id: (cpu_index / smp_threads) * spapr->vsmt + cpu_index % smp_threads (core_id / smp_threads) * spapr->vsmt (1 user) index * spapr->vsmt (2 users) or guess that the VCPU id of a given VCPU is the first thread of a virtual core: index % spapr->vsmt != 0 Even if the numbering logic isn't that complex, it is rather fragile to have these assumptions open-coded in several places. FWIW this was proved with recent issues related to VSMT. This patch moves the VCPU id formula to a single function to be called everywhere the code needs to compute one. It also adds an helper to guess if a VCPU is the first thread of a VCORE.

2018-02-16spapr: rename spapr_vcpu_id() to spapr_get_vcpu_id()Greg Kurz
The spapr_vcpu_id() function is an accessor actually. Let's rename it for symmetry with the recently added spapr_set_vcpu_id() helper. The motivation behind this is that a later patch will consolidate the VCPU id formula in a function and spapr_vcpu_id looks like an appropriate name.

2018-02-16spapr: move VCPU calculation to core machine codeGreg Kurz
The VCPU ids are currently computed and assigned to each individual CPU threads in spapr_cpu_core_realize(). But the numbering logic of VCPU ids is actually a machine-level concept, and many places in hw/ppc/spapr.c also have to compute VCPU ids out of CPU indexes. The current formula used in spapr_cpu_core_realize() is: vcpu_id = (cc->core_id * spapr->vsmt / smp_threads) + i where: cc->core_id is a multiple of smp_threads cpu_index = cc->core_id + i 0 <= i < smp_threads So we have: cpu_index % smp_threads == i cc->core_id / smp_threads == cpu_index / smp_threads hence: vcpu_id = (cpu_index / smp_threads) * spapr->vsmt + cpu_index % smp_threads; This formula was used before VSMT at the time VCPU ids where computed at the target emulation level. It has the advantage of being useable to derive a VPCU id out of a CPU index only. It is fitted for all the places where the machine code has to compute a VCPU id. This patch introduces an accessor to set the VCPU id in a PowerPCCPU object using the above formula. It is a first step to consolidate all the VCPU id logic in a single place.
