2018-02-09Fix configure for s390 qemu on alpine and other busybox environmentsAlice Frosi
In alpine docker image the qemu-system-s390x build is broken and it throws this error: qemu-system-s390x: Initialization of device s390-ipl failed: could not load bootloader 's390-ccw.img' The grep command of busybox uses regex. This fails on binary data (e.g. stops on every \0), so it does not identify the string BiGeNdIaN in the test case big/little. Therefore, it assumes that the architecture is little endian.

2018-01-12build-sys: compile with -Og or -O1 when --enable-debugMarc-André Lureau
When --enable-debug is turned on, configure doesn't set -O level, and uses default compiler -O0 level, which is slow. Instead, use -Og if supported by the compiler (optimize debugging experience), or -O1 (keeps code somewhat debuggable and works around compiler bugs). Unfortunately, gcc has many false-positive maybe-uninitialized errors with Og and O1 (f27 gcc 7.2.1 20170915): /home/elmarco/src/qemu/hw/ipmi/isa_ipmi_kcs.c: In function ‘ipmi_kcs_ioport_read’: /home/elmarco/src/qemu/hw/ipmi/isa_ipmi_kcs.c:279:12: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized] return ret; ^~~ cc1: all warnings being treated as errors make: *** [/home/elmarco/src/qemu/rules.mak:66: hw/ipmi/isa_ipmi_kcs.o] Error 1 make: *** Waiting for unfinished jobs.... /home/elmarco/src/qemu/hw/ide/ahci.c: In function ‘ahci_populate_sglist’: /home/elmarco/src/qemu/hw/ide/ahci.c:903:58: error: ‘tbl_entry_size’ may be used uninitialized in this function [-Werror=maybe-uninitialized] if ((off_idx == -1) || (off_pos < 0) || (off_pos > tbl_entry_size)) { ~~~~~~~~~^~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make: *** [/home/elmarco/src/qemu/rules.mak:66: hw/ide/ahci.o] Error 1 /home/elmarco/src/qemu/hw/display/qxl.c: In function ‘qxl_add_memslot’: /home/elmarco/src/qemu/hw/display/qxl.c:1397:52: error: ‘pci_start’ may be used uninitialized in this function [-Werror=maybe-uninitialized] memslot.virt_end = virt_start + (guest_end - pci_start); ~~~~~~~~~~~~~^~~~~~~~~~~~ /home/elmarco/src/qemu/hw/display/qxl.c:1389:9: error: ‘pci_region’ may be used uninitialized in this function [-Werror=maybe-uninitialized] qxl_set_guest_bug(d, "%s: pci_region = %d", __func__, pci_region); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors There seems to be a long list of related bugs in upstream GCC, some of them are being fixed very recently: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=24639 For now, let's workaround it by using Wno-maybe-uninitialized (gcc-only).

2018-01-12build-sys: fix qemu-ga -pthread linkingMarc-André Lureau
When linking qemu-ga under some configuration (when gthread-2.0.pc doesn't have -pthread, as happening atm with meson build), you may have this linking issue: /usr/bin/ld: libqemuutil.a(qemu-thread-posix.o): undefined reference to symbol 'pthread_setname_np@@GLIBC_2.12' /usr/lib64/libpthread.so.0: error adding symbols: DSO missing from command line Make sure qemu-ga links with the pthread library, by adding correct flags to libs_qga. This is really a QEMU bug, because it's QEMU code that's using pthread functions, and so we must explicitly link against pthreads. The bug was just masked by the fact that often some pkg-config or another for one of our dependencies will add -pthread to the link line anyway.

2017-12-22i386: hvf: add code base from Google's QEMU repositorySergio Andres Gomez Del Real
This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

2017-12-21rcu: reduce more than 7MB heap memory by malloc_trim()Yang Zhong
Since there are some issues in memory alloc/free machenism in glibc for little chunk memory, if Qemu frequently alloc/free little chunk memory, the glibc doesn't alloc little chunk memory from free list of glibc and still allocate from OS, which make the heap size bigger and bigger. This patch introduce malloc_trim(), which will free heap memory when there is no rcu call during rcu thread loop. malloc_trim() can be enabled/disabled by --enable-malloc-trim/ --disable-malloc-trim in the Qemu configure command. The default malloc_trim() is enabled for libc. Below are test results from smaps file.

2017-12-18configure: check $CC available before verifying host CPUDaniel Henrique Barboza
When executing 'configure' in a fresh QEMU clone, in a fresh OS install running in a ppc64le host, this is the error shown: ----- ../configure --enable-trace-backend=simple --enable-debug --target-list=ppc64-softmmu ERROR: Unsupported CPU = ppc64le, try --enable-tcg-interpreter ----- This isn't true, ppc64le host CPU is supported. This happens because, in a fresh install, we don't have a C compiler to autodetect the $cpu variable to "ppc64". This patch moves the CC available check up a bit, just before verifying the host CPU. This ensures that we bail out with a $CC not available error instead of unsupported CPU (the host CPU detection without the compiler wouldn't work properly anyway). It also allows --help to keep working without a C compiler. With this patch, in the same ppc64le host without gcc: $ ../configure --enable-trace-backend=simple --enable-debug --target-list=ppc64-softmmu ERROR: "cc" either does not exist or does not work $ ../configure --help Usage: configure [options] Options: [defaults in brackets after descriptions] Standard options: --help print this message --prefix=PREFIX install in PREFIX [/usr/local] --interp-prefix=PREFIX where to find shared libraries, etc. (...)

In such a case 'scripts/git-submodules.sh update' will always fail and users are required to run it manually themselves on their original writable source directory. While this is already supported, it is nice to give users a command line flag to configure to permanently disable automatic submodule updates, as it means they won't get hard to diagnose failures from git-submodules.sh at an arbitrary later date. This patch thus introduces a flag '--disable-git-update' which will prevent 'make' from ever running 'scripts/git-submodules.sh update'. It will still run the 'status' command to determine if a submodule update is needed, but when it does this it'll simply stop and print a message instructing the developer what todo. eg $ ./configure --target-list=x86_64-softmmu --disable-git-update ...snip... $ make GEN config-host.h GEN trace/generated-tcg-tracers.h GEN trace/generated-helpers-wrappers.h GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.

2017-11-06build: allow setting a custom GIT binary for transparent proxyingDaniel P. Berrange
Some users can't run a bare 'git' command, due to need for a transparent proxying solution such as 'tsocks'. This adds an argument to configure to let users specify such a thing: ./configure --with-git="tsocks git" The submodule script is also updated to give the user a hint about using this flag, if we fail to checkout modules.

2017-10-16build: automatically handle GIT submodule checkout for dtcDaniel P. Berrange
Currently if DTC is required by configure and not available in the host OS install, we exit with an error message telling the user to checkout a git submodule or install the library. This introduces automatic handling of the git submodule checkout process and enables it for dtc. This only runs if building from GIT, so users of release tarballs still need the system library install. The current state of the git checkout is stashed in .git-submodule-status, and a helper program is used to determine if this state matches the desired submodule state. A dependency against 'Makefile' ensures that the submodule state is refreshed at the start of the build process Signed-off-by: Daniel P.

2017-10-13tpm: Added support for TPM emulatorAmarnath Valluri
This change introduces a new TPM backend driver that can communicate with swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to the TPM emulator using QEMU's socket-based chardev backend device. Swtpm uses two Unix sockets for communications, one for plain TPM commands and responses, and one for out-of-band control messages. QEMU passes the data socket to be used over the control channel. The swtpm and associated tools can be found here: https://github.com/stefanberger/swtpm The swtpm's control channel protocol specification can be found here: https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification Usage: # setup TPM state directory mkdir /tmp/mytpm chown -R tss:root /tmp/mytpm /usr/bin/swtpm_setup --tpm-state /tmp/mytpm --createek # Ask qemu to use TPM emulator with given tpm state directory qemu-system-x86_64 \ [...] \ -chardev socket,id=chrtpm,path=/tmp/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis,tpmdev=tpm0 \ [...] Signed-off-by: Amarnath Valluri <amarnath.valluri@intel.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>

Add a firmware path config option to configure. Multiple directories are accepted, with the usual colon as separator. Default value is ${prefix}/share/qemu-firmware. The path is searched in addition to the current search path (typically ${prefix}/share/qemu). This prepares qemu for the planned split of the prebuilt firmware blobs into a separate project. Distributions can also use this to get rid of the firmware symlink farm and add -- for example -- /usr/share/seabios to the firmware path instead.

2017-09-26util/qemu-thread-posix.c: Replace OS ifdefs with CONFIG_HAVE_SEM_TIMEDWAITPeter Maydell
In qemu-thread-posix.c we have two implementations of the various qemu_sem_* functions, one of which uses native POSIX sem_* and the other of which emulates them with pthread conditions. This is necessary because not all our host OSes support sem_timedwait(). Instead of a hard-coded list of OSes which don't implement sem_timedwait(), which gets out of date, make configure test for the presence of the function and set a new CONFIG_HAVE_SEM_TIMEDWAIT appropriately. In particular, newer NetBSDs have sem_timedwait(), so this commit will switch them over to using it. OSX still does not have an implementation.

2017-09-22scsi: add multipath support to qemu-pr-helperPaolo Bonzini
Proper support of persistent reservation for multipath devices requires communication with the multipath daemon, so that the reservation is registered and applied when a path comes up. The device mapper utilities provide a library to do so; this patch makes qemu-pr-helper.c detect multipath devices and, when one is found, delegate the operation to libmpathpersist.

2017-09-22scsi: build qemu-pr-helperPaolo Bonzini
Introduce a privileged helper to run persistent reservation commands. This lets virtual machines send persistent reservations without using CAP_SYS_RAWIO or out-of-tree patches. The helper uses Unix permissions and SCM_RIGHTS to restrict access to processes that can access its socket and prove that they have an open file descriptor for a raw SCSI device. The next patch will also correct the usage of persistent reservations with multipath devices. It would also be possible to support for Linux's IOC_PR_* ioctls in the future, to support NVMe devices. For now, however, only SCSI is supported. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
