2020-06-26configure: add libdaxctl supportJingqi Liu1-0/+29
Add a pair of configure options --{enable,disable}-libdaxctl to control whether QEMU is compiled with libdaxctl [1]. Libdaxctl is a utility library for managing the device dax subsystem. QEMU uses mmap(2) to maps vNVDIMM backends and aligns the mapping address to the page size (getpagesize(2)) by default. However, some types of backends may require an alignment different than the page size. The 'align' option is provided to memory-backend-file to allow users to specify the proper alignment. For device dax (e.g., /dev/dax0.0), the 'align' option needs to match the alignment requirement of the device dax, which can be fetched through the APIs of libdaxctl version 57 or up. [1] Libdaxctl is a part of ndctl project. The project's repository is: https://github.com/pmem/ndctl For more information about libdaxctl APIs, you can refer to the comments in source code of: pmem/ndctl/daxctl/lib/libdaxctl.c.

2020-06-23configure: add flags to support SafeStackDaniele Buono1-0/+73
This patch adds a flag to enable/disable the SafeStack instrumentation provided by LLVM. On enable, make sure that the compiler supports the flags, and that we are using the proper coroutine implementation (coroutine-ucontext). On disable, explicitly disable the option if it was enabled by default. While SafeStack is supported only on Linux, NetBSD, FreeBSD and macOS, we are not checking for the O.S. since this is already done by LLVM.

2020-06-18configure: Add -Wno-psabiRichard Henderson1-0/+1
On aarch64, gcc 9.3 is generating qemu/exec.c: In function ‘address_space_translate_iommu’: qemu/exec.c:431:28: note: parameter passing for argument of type \ ‘MemTxAttrs’ {aka ‘struct MemTxAttrs’} changed in GCC 9.1 and many other repetitions. This structure, and the functions amongst which it is passed, are not part of a QEMU public API. Therefore we do not care how the compiler passes the argument, so long as the compiler is self-consistent. The only portion of QEMU which does have a public api, and so must have a stable abi, is "qemu/plugin.h". We test this by forcing -Wpsabi in tests/plugin/Makefile.

2020-05-14target/arm: Use correct GDB XML for M-profile coresPeter Maydell1-2/+2
GDB's remote protocol requires M-profile cores to use the feature name 'org.gnu.gdb.arm.m-profile' instead of the 'org.gnu.gdb.arm.core' feature used for A- and R-profile cores. We weren't doing this, which meant GDB treated our M-profile cores like A-profile ones. This mostly doesn't matter, but for instance means that it doesn't correctly handle backtraces where an M-profile exception frame is involved. Ship a copy of GDB's arm-m-profile.xml and use it on the M-profile cores. The integer registers have the same offsets as the arm-core.xml, but register 25 is the M-profile XPSR rather than the A-profile CPSR, so we need to update arm_cpu_gdb_read_register() and arm_cpu_gdb_write_register() to handle XSPR reads and writes.

2020-05-06target/m68k: fix gdb for m68xxxKONRAD Frederic1-1/+1
Currently "cf-core.xml" is sent to GDB when using any m68k flavor. Thing is it uses the "org.gnu.gdb.coldfire.core" feature name and gdb 8.3 then expects a coldfire FPU instead of the default m68881 FPU. This is not OK because the m68881 floats registers are 96 bits wide so it crashes GDB with the following error message: (gdb) target remote localhost:7960 Remote debugging using localhost:7960 warning: Register "fp0" has an unsupported size (96 bits) warning: Register "fp1" has an unsupported size (96 bits) ... Remote 'g' packet reply is too long (expected 148 bytes, got 180 bytes): \ 00000000000[...]0000 With this patch: qemu-system-m68k -M none -cpu m68020 -s -S (gdb) tar rem :1234 Remote debugging using :1234 warning: No executable has been specified and target does not support determining executable automatically.

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.

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.

2020-03-28configure: Do not force pie=no for non-x86Richard Henderson1-10/+0
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.

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.

2020-03-27configure: disable MTTCG for MIPS guestsAlex Bennée1-1/+1
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.
