* configure: Honour --disable-werror for SphinxPeter Maydell2020-04-141-1/+8
| | | | | | | | | | | | | | | If we are not making warnings fatal for compilation, make them non-fatal when building the Sphinx documentation also. (For instance Sphinx 3.0 warns about some constructs that older versions were happy with, which is a build failure if we use the warnings-as-errors flag.) This provides a workaround at least for LP:1872113.

| | | | | | | | | | | | | Without -Werror, the probe may succeed, but then compilation fails later when -Werror is added for other reasons.

| | | | | | | | | | | | | | Recent toolchains support static and pie at the same time. As with normal dynamic builds, allow --static to default to PIE if supported by the toolchain.

| | | | | | | | | | | | | | | Some distributions, e.g. Ubuntu 19.10, enable PIE by default. If for some reason one wishes to build a non-pie binary, we must provide additional options to override. At the same time, reorg the code to an elif chain.

| | | | | | | | | | | | | The CFLAGS_NOPIE and LDFLAGS_NOPIE variables are used in pc-bios/optionrom/Makefile, which has nothing to do with the PIE setting of the main qemu executables.

* configure: Do not force pie=no for non-x86Richard Henderson2020-03-281-10/+0Star
| | | | | | | | | | | | | | | | | | | | | PIE is supported on many other hosts besides x86. The default for non-x86 is now the same as x86: pie is used if supported, and may be forced via --enable/--disable-pie. The original commit (40d6444e91c) said: "Non-x86 are not changed, as they require TCG changes" but I think that's wrong -- there's nothing about PIE that affects TCG one way or another. Tested on aarch64 (bionic) and ppc64le (centos 7) hosts.

* configure: Drop adjustment of textsegRichard Henderson2020-03-281-47/+0Star
| | | | | | | | | | | | | | | | This adjustment was random and unnecessary. The user mode startup code in probe_guest_base() will choose a value for guest_base that allows the host qemu binary to not conflict with the guest binary. With modern distributions, this isn't even used, as the default is PIE, which does the same job in a more portable way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While debugging check-acceptance failures I found an instability in the mips64el test case. Briefly the test case: retry.py -n 100 -c -- ./mips64el-softmmu/qemu-system-mips64el \ -display none -vga none -serial mon:stdio \ -machine malta -kernel ./vmlinux-4.7.0-rc1.I6400 \ -cpu I6400 -smp 8 -vga std \ -append "printk.time=0 clocksource=GIC console=tty0 console=ttyS0 panic=-1" \ --no-reboot Reports about a 9% failure rate: Results summary: 0: 91 times (91.00%), avg time 5.547 (0.45 varience/0.67 deviation) -6: 9 times (9.00%), avg time 3.394 (0.02 varience/0.13 deviation) Ran command 100 times, 91 passes When re-run with "--accel tcg,thread=single" the instability goes away. Results summary: 0: 100 times (100.00%), avg time 17.318 (249.76 varience/15.80 deviation) Ran command 100 times, 100 passes Which seems to indicate there is some aspect of the MIPS MTTCG fixes that has been missed. Ideally we would fix that but I'm afraid I don't have time to investigate and am not super familiar with the architecture anyway. In lieu of someone tracking down the failure lets disable it for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glib's G_DEFINE_AUTOPTR_CLEANUP_FUNC() macro defines several static inline functions, often with some of them unused, but prior to 2.57.2 did not mark the functions as such. As a result, clang (but not gcc) fails to build with older glib unless -Wno-unused-function is enabled.

This may have been true of the first few operations, but is not true of all operations. In particular, multiply, shift by scalar, and compare of 8- and 16-bit elements are not expanded inline if host vector operations are not supported. For an x86_64 host that does not support AVX, this means that we will fall back to the helper, which will attempt to use SSE instructions, which will SEGV on an invalid 8-byte aligned memory operation. This patch simply removes the CONFIG_VECTOR16 code and configuration without further simplification.

For example: <linux/mman.h> and <sys/mman.h> duplicate some macro definitions. We normally never see those warnings because GCC suppresses warnings generated by system headers. We carry our own copy of Linux header files, though, and this makes those warnings not be suppressed when glibc headers are included before Linux headers (e.g. if <sys/mman.h> is included before <linux/mman.h>). Use -isystem instead of -I for linux-headers. This makes the compiler treat our linux-headers directory the same way it treats system-provided Linux headers, and suppress warnings generated by them.

QEMU also re-defines it in "qemu/osdep.h". The two definitions then clash on a MinGW build. We can avoid the SASL definition by defining STRUCT_IOVEC_DEFINED. Since QEMU already defines 'struct iovec' if it is missing, add the definition to vnc_sasl_cflags to avoid SASL re-defining it.

But on the other hand since a qemu process represents a guest instance it is usually kept around. That makes late addition of dynamic features e.g. 'hot-attach of a ceph disk' fail by trying to load a new version of e.f. block-rbd.so into an old still running qemu binary. This adds a fallback to also load modules from a versioned directory in the temporary /var/run path. That way qemu is providing a way for packaging to store modules of an upgraded qemu package as needed until the next reboot. An example how that can then be used in packaging can be seen in: https://git.launchpad.net/~paelzer/ubuntu/+source/qemu/log/?h=bug-1847361-miss-old-so-on-upgrade-UBUNTU Fixes: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1847361 Signed-off-by: Christian Ehrhardt <christian.ehrhardt@canonical.com> Reviewed-by: Daniel P.

* | aio-posix: add io_uring fd monitoring implementationStefan Hajnoczi2020-03-091-0/+5
|/ | | | | | | | | | | | | | | | | | The recent Linux io_uring API has several advantages over ppoll(2) and epoll(2). Details are given in the source code. Add an io_uring implementation and make it the default on Linux. Performance is the same as with epoll(7) but later patches add optimizations that take advantage of io_uring. It is necessary to change how aio_set_fd_handler() deals with deleting AioHandlers since removing monitored file descriptors is asynchronous in io_uring. fdmon_io_uring_remove() marks the AioHandler deleted and aio_set_fd_handler() will let it handle deletion in that case.

This means that "no sphinx-build at all" and "sphinx-build exists but is too old" are both reported the same way. Further, we want to assume that all the Python we write is running with at least Python 3.5; configure checks that for our scripts, but Sphinx extensions run with whatever Python version sphinx-build itself is using. Add a check to our conf.py which makes sphinx-build fail if it would be running our extensions with an old Python, and handle this in configure so we can report failure helpfully to the user. This will mean that configure --enable-docs will fail like this if the sphinx-build provided is not suitable: Warning: sphinx-build exists but it is either too old or uses too old a Python version ERROR: User requested feature docs configure was not able to find it.
