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.

2020-05-13qcow2: add zstd cluster compressionDenis Plotnikov1-1/+1
zstd significantly reduces cluster compression time. It provides better compression performance maintaining the same level of the compression ratio in comparison with zlib, which, at the moment, is the only compression method available.

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) ...

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.

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.

2020-03-18build: Silence clang warning on older glib autoptr usageEric Blake1-0/+20
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.

2020-03-17tcg: Remove CONFIG_VECTOR16Richard Henderson1-56/+0
The comment in tcg-runtime-gvec.c about CONFIG_VECTOR16 says that tcg-op-gvec.c has eliminated size 8 vectors, and only passes on multiples of 16. 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.

2020-03-16Use -isystem for linux-headers dirEduardo Habkost1-1/+1
glibc and Linux-provided headers are known to generate macro redefinition warnings when used together. 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.

2020-03-16configure: Fix building with SASL on WindowsPhilippe Mathieu-Daudé1-1/+3
The Simple Authentication and Security Layer (SASL) library re-defines the struct iovec on Win32 [*]. 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.

2020-03-16modules: load modules from versioned /var/run dirChristian Ehrhardt1-0/+15
On upgrades the old .so files usually are replaced. 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.
