2018-10-02contrib: add elf2dmp toolViktor Prutyanov
elf2dmp is a converter from ELF dump (produced by 'dump-guest-memory') to Windows MEMORY.DMP format (also know as 'Complete Memory Dump') which can be opened in WinDbg. This tool can help if VMCoreInfo device/driver is absent in Windows VM and 'dump-guest-memory -w' is not available but dump can be created in ELF format. The tool works as follows: 1. Determine the system paging root looking at GS_BASE or KERNEL_GS_BASE to locate the PRCB structure and finds the kernel CR3 nearby if QEMU CPU state CR3 is not suitable. 2. Find an address within the kernel image by dereferencing the first IDT entry and scans virtual memory upwards until the start of the kernel. 3. Download a PDB matching the kernel from the Microsoft symbol store, and figure out the layout of certain relevant structures necessary for the dump. 4. Populate the corresponding structures in the memory image and create the appropriate dump header.

2018-10-02configure: preserve various environment variables in config.statusDaniel P. Berrangé
The config.status script is auto-generated by configure upon completion. The intention is that config.status can be later invoked by the developer directly, or by make indirectly, to re-detect the same environment that configure originally used. The current config.status script, however, only contains a record of the command line arguments to configure. Various environment variables have an effect on what configure will find. In particular PKG_CONFIG_LIBDIR & PKG_CONFIG_PATH vars will affect what libraries pkg-config finds. The PATH var will affect what toolchain binaries and XXXX-config scripts are found. The LD_LIBRARY_PATH var will affect what libraries are found. Most commands have env variables that will override the name/path of the default version configure finds. All these key env variables should be recorded in the config.status script. Autoconf would also preserve CFLAGS, LDFLAGS, LIBS, CPPFLAGS, but QEMU deals with those differently, expecting extra flags to be set using configure args, rather than env variables. At the end of the script we also don't have the original values of those env vars, as we modify them during configure.

2018-09-27display/edid: add edid generator to qemu.Gerd Hoffmann
EDID is a metadata format to describe monitors. On physical hardware the monitor has an eeprom with that data block which can be read over i2c bus. On a linux system you can usually find the EDID data block in /sys/class/drm/$card/$connector/edid. xorg ships a edid-decode utility which you can use to turn the blob into readable form. I think it would be a good idea to use EDID for virtual displays too. Needs changes in both qemu and guest kms drivers. This patch is the first step, it adds an generator for EDID blobs to qemu. Comes with a qemu-edid test tool included. With EDID we can pass more information to the guest. Names and serial numbers, so the guests display configuration has no boring "Unknown Monitor". List of video modes. Display resolution, pretty important in case we want add HiDPI support some day.

2018-08-23qemu-pr-helper: Fix build on CentOS 7Murilo Opsfelder Araujo
After commit b3f1c8c413bc83e4a2cc7a63e4eddf9fe6449052 "qemu-pr-helper: use new libmultipath API", QEMU started using new libmultipath API, which is not available on CentOS 7.x. This fixes that by probing the new libmultipath API in configure. If it fails, then try probing the old API. If it fails, then consider libmultipath not available. With this, configure script defines CONFIG_MPATH_NEW_API that is used in scsi/qemu-pr-helper.c to use the new libmultipath API.

2018-08-10configure: add libpmem supportJunyan He
Add a pair of configure options --{enable,disable}-libpmem to control whether QEMU is compiled with PMDK libpmem [1]. QEMU may write to the host persistent memory (e.g. in vNVDIMM label emulation and live migration), so it must take the proper operations to ensure the persistence of its own writes. Depending on the CPU models and available instructions, the optimal operation can vary [2]. PMDK libpmem have already implemented those operations on multiple CPU models (x86 and ARM) and the logic to select the optimal ones, so QEMU can just use libpmem rather than re-implement them. Libpem is a part of PMDK project(formerly known as NMVL). The project's home page is: http://pmem.io/pmdk/ And the project's repository is: https://github.com/pmem/pmdk/ For more information about libpmem APIs, you can refer to the comments in source code of: pmdk/src/libpmem/pmem.c, begin at line 33.

2018-06-29glib: bump min required glib library version to 2.40Daniel P. Berrangé
Per supported platforms doc[1], the various min glib on relevant distros is: RHEL-7: 2.50.3 Debian (Stretch): 2.50.3 Debian (Jessie): 2.42.1 OpenBSD (Ports): 2.54.3 FreeBSD (Ports): 2.50.3 OpenSUSE Leap 15: 2.54.3 SLE12-SP2: 2.48.2 Ubuntu (Xenial): 2.48.0 macOS (Homebrew): 2.56.0 This suggests that a minimum glib of 2.42 is a reasonable target. The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only has glib 2.40.0, and this is needed for testing during merge. Thus an exception is made to the documented platform support policy to allow for all three current LTS releases to be supported. Docker jobs that not longer satisfy this new min version are removed.

2018-06-01WHPX: dynamically load WHP librariesLucian Petrut
We're currently linking against import libraries of the WHP DLLs. By dynamically loading the libraries, we ensure that QEMU will work on previous Windows versions, where the WHP DLLs will be missing (assuming that WHP is not requested). Also, we're simplifying the build process, as we no longer require the import libraries.

The configure script outputs "yes" regardless which libfdt is used: ./configure [...] fdt support yes Sometimes you can have both system and local git version available, change the configure script to display which library got selected: debian8$ dpkg-query --showformat='${Version}\n' --show libfdt-dev 1.4.0+dfsg-1 debian8$ ./configure [...] fdt support git Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20180415230522.24404-3-f4bug@amsat.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2018-05-11configure: Really use local libfdt if the system one is too oldPhilippe Mathieu-Daudé
QEMU requires libfdt version >= 1.4.2. If the host has an older libfdt installed, the configure script will use a (git cloned) local version. Example with Debian 8: $ dpkg-query --showformat='${Version}\n' --show libfdt-dev 1.4.0+dfsg-1 $ ./configure [...] fdt support yes # from git submodule 'dtc' If this case occurs, the linker will have 2 different libfdt available in the library search path. The default behavior is to search the system path first, then the local path. Even if the configure script noticed the libfdt is too old and clone a more recent locally, when linking the system library is selected first, and the link process eventually fails: LINK mips64el-softmmu/qemu-system-mips64el ../hw/core/loader-fit.o: In function `load_fit': /root/src/github.com/philmd/qemu/hw/core/loader-fit.c:278: undefined reference to `fdt_first_subnode' /root/src/github.com/philmd/qemu/hw/core/loader-fit.c:286: undefined reference to `fdt_next_subnode' /root/src/github.com/philmd/qemu/hw/core/loader-fit.c:277: undefined reference to `fdt_first_subnode' collect2: error: ld returned 1 exit status Makefile:201: recipe for target 'qemu-system-mips64el' failed make[1]: *** [qemu-system-mips64el] Error 1 QEMU already uses a kludge to enforce local CFLAGS before system ones for libpixman and libfdt, add a similar kludge for the LDFLAGS to enforce using the local libfdt.

This makes it much easier to find a particular thing in config.log. We have to use the ${BASH_LINENO[*]} syntax which is a syntax error in other shells, so test what shell we are running and use eval. The extra output is only printed if configure is run with bash. On systems where /bin/sh is not bash, it is necessary to say bash ./configure to get the extra debug info in the log.

2018-04-26xen: Use newly added dmops for mapping VGA memoryRoss Lagerwall
Xen unstable (to be in 4.11) has two new dmops, relocate_memory and pin_memory_cacheattr. Use these to set up the VGA memory, replacing the previous calls to libxc. This allows the VGA console to work properly when QEMU is running restricted (-xen-domid-restrict). Wrapper functions are provided to allow QEMU to work with older versions of Xen. Tweak the error handling while making this change: * Report pin_memory_cacheattr errors. * Report errors even when DEBUG_HVM is not set. This is useful for trying to understand why VGA is not working, since otherwise it just fails silently. * Fix the return values when an error occurs. The functions now consistently return -1 and set errno.
