      configure: Add support for tcmalloc · 2847b469
      由 Fam Zheng 提交于 
      This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.

tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.

It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.

An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:

      Revert seccomp tests that allow it to be used on non-x86 architectures · ae6e8ef1
      由 Peter Maydell 提交于 
      Unfortunately it turns out that libseccomp 2.2 still does not work
correctly on non-x86 architectures; return to the previous configure
setup of insisting on libseccomp 2.1 or better and i386/x86_64 and
disabling seccomp support in all other situations.

This reverts the two commits:
 * "seccomp: libseccomp version varying according to arch"
   (commit 896848f0)
 * "seccomp: update libseccomp version and remove arch restriction"
   (commit 8e27fc20)

      configure: Build GDB XML for 32 bit ARM CPUs into qemu aarch64 binaries · 8f95ce2e
      由 Peter Maydell 提交于 
      The qemu-aarch64 and qemu-system-aarch64 binaries include support
for all the 32 bit ARM CPUs as well as the 64 bit ones. This means
we need to build in the GDB XML files for the 32 bit CPUs too.
Otherwise gdb will complain:
 warning: while parsing target description (at line 1): Could not load XML document "arm-core.xml"
when you try to connect to our gdbserver to debug a 32 bit CPU
running in a qemu-aarch64 or qemu-system-aarch64 binary.

      tests: disable global props test for old glib · 9d41401b
      由 Michael S. Tsirkin 提交于 
      follow-up patch moves global property tests to subprocesses.
Unfortunately with old glib this causes:

tests/test-qdev-global-props.c: In function
‘test_static_prop’:
tests/test-qdev-global-props.c:80:5: error: implicit
declaration of function ‘g_test_trap_subprocess’
[-Werror=implicit-function-declaration]
tests/test-qdev-global-props.c:80:5: error: nested extern
declaration of ‘g_test_trap_subprocess’ [-Werror=nested-externs]

This function was only added in glib 2.38, and our
minimum version is 2.12.

To fix, disable the test for glib < 2.38.

Apply before that patch to avoid breaking bisect.

      configure: check for pixman-1 version · 236f282c
      由 Hu Tao 提交于 
      commit a93a3af9 introduces use of PIXMAN_TYPE_RGBA, but it's only available
in pixman >= 0.21.8. If pixman doesn't meet the version requirement, qemu
will fail to build with following message:

qemu/ui/qemu-pixman.c: In function ‘qemu_pixelformat_from_pixman’:
qemu/ui/qemu-pixman.c:42: error: ‘PIXMAN_TYPE_RGBA’ undeclared (first use in this function)
qemu/ui/qemu-pixman.c:42: error: (Each undeclared identifier is reported only once
qemu/ui/qemu-pixman.c:42: error: for each function it appears in.)

This patch fixes the problem by checking the pixman version.
