2015-11-05target-i386: Remove SSE4a from qemu64 CPU modelEduardo Habkost
SSE4a is not available in any Intel CPU, and we want to make the default CPU runnable in most hosts, so it doesn't make sense to enable it by default in KVM mode. We should eventually have all features supported by TCG enabled by default in TCG mode, but as we don't have a good mechanism today to ensure we have different defaults in KVM and TCG mode, disable SSE4a in the qemu64 CPU model entirely.

2015-11-05target-i386: Set "check=off" by default on pc-*-2.4 and olderEduardo Habkost
The default CPU model (qemu64) have some issues today: it enables some features (ABM and SSE4a) that are not present in many host CPUs. That means many hosts (but not all of them) had those features silently disabled in the default configuration in QEMU 2.4 and older. With the new "check=on" default, this causes warnings to be printed in the default configuration, because of the lack of SSE4A on all Intel hosts, and the lack of ABM on Sandy Bridge and older hosts: $ qemu-system-x86_64 -machine pc,accel=kvm warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5] warning: host doesn't support requested feature: CPUID.80000001H:ECX.sse4a [bit 6] Those issues will be fixed in pc-*-2.5 and newer. But as we can't change the guest ABI in pc-*-2.4, disable "check" mode by default in pc-*-2.4 and older so we don't print spurious warnings.

2015-11-05kvmclock: add a new function to update env->tsc.Liang Li
The commit 317b0a6d8 fixed an issue which caused by the outdated env->tsc value, but the fix lead to 'cpu_synchronize_all_states()' called twice during live migration. The 'cpu_synchronize_all_states()' takes about 130us for a VM which has 4 vcpus, it's a bit expensive. Synchronize the whole CPU context just for updating env->tsc is too wasting, this patch use a new function to update the env->tsc. Comparing to 'cpu_synchronize_all_states()', it only takes about 20us.

2015-11-05configure: disable FORTIFY_SOURCE under clangJohn Snow
Some versions of clang may have difficulty compiling glibc headers when -D_FORTIFY_SOURCE is used. For example, Clang++ 3.5.0-9.fc22 cannot compile glibc's stdio headers when -D_FORTIFY_SOURCE=2 is used. This manifests currently as build failures with clang and any arm target. According to LLVM dev Richard Smith, clang does not target or support FORTIFY_SOURCE + glibc, and it should not be relied on. "It's still an unsupported combination, and while it might compile, some of the checks are unlikely to work because they require a frontend inliner to be useful" See: http://lists.llvm.org/pipermail/cfe-dev/2015-November/045846.html Conclusion: disable fortify-source if we appear to be using clang instead of testing for compile success or failure, which may be incidental or not indicative of proper support of the feature.

2015-11-04backends/hostmem-file: Allow to specify full pathname for backing filePavel Fedin
This allows to explicitly specify file name to use with the backend. This is important when using it together with ivshmem in order to make it backed by hugetlbfs. By default filename is autogenerated using mkstemp(), and the file is unlink()ed after creation, effectively making it anonymous. This is not very useful with ivshmem because it ends up in a memory which cannot be accessed by something else. Distinction between directory and file name is done by stat() check. If an existing directory is given, the code keeps old behavior. Otherwise it creates or opens a file with the given pathname.

If the user is using ccache during the configuration step, it may interfere with some of the configuration tests, particularly the "Is ccache interfering with macro analysis" step, which is a bit of a poetic problem. 1) Disallow ccache from reading from the cache during configure, but don't disable it entirely to allow us to see if it causes other problems. 2) Force off CCACHE_CPP2 during the ccache test to get a deterministic answer over whether or not we need to enable that feature later.

2015-11-04cpu-exec: Fix compiler warning (-Werror=clobbered)Stefan Weil
Reloading of local variables after sigsetjmp is only needed for some buggy compilers. The code which should reload these variables causes compiler warnings with gcc 4.7 when compiler optimizations are enabled: cpu-exec.c:204:15: error: variable ‘cpu’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered] cpu-exec.c:207:15: error: variable ‘cc’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered] cpu-exec.c:202:28: error: argument ‘env’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Werror=clobbered] Now this code is only used for compilers which need it (and gcc 4.5.x, x > 0 which does not need it but won't give warnings). There were bug reports for clang and gcc 4.5.0, while gcc 4.5.1 was reported to work fine without the reload code. For clang it is not clear which versions are affected, so simply keep the status quo for all clang compilations. This can be improved later.

2015-11-04memory: call begin, log_start and commit when registering a new listenerPaolo Bonzini
This ensures that cpu_reload_memory_map() is called as soon as tcg_cpu_address_space_init() is called, and before cpu->memory_dispatch is used. qemu-system-s390x never changes the address spaces after tcg_cpu_address_space_init() is called, and thus tcg_commit() is never called. This causes a SIGSEGV. Because memory_map_init() will now call mem_commit(), we have to initialize io_mem_* before address_space_memory and friends.

2015-11-04pc: Set hw_version on all machine classesEduardo Habkost
In 2012, QEMU had a bug where it exposed QEMU version information to the guest, meaning a QEMU upgrade would expose different hardware to the guest OS even if the same machine-type is being used. The bug was fixed by commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4, on all machines up to pc-1.0. But we kept introducing the same bug on all newer machines since then. That means we are breaking guest ABI every time QEMU was upgraded. Fix this by setting the hw_version on all PC machines, making sure the hardware won't change when upgrading QEMU. Note that QEMU_VERSION was "1.0" in QEMU 1.0, but starting on QEMU 1.1.0, it started following the "x.y.0" pattern. We have to follow it, to make sure we use the right QEMU_VERSION string from each QEMU release. The 2.5 machine classes could have hw_version unset, because the default value for qemu_get_version() is QEMU_VERSION. But I decided to set it explicitly to QEMU_VERSION so we don't forget to update it to "2.5.0" after we release 2.5.0 and create a 2.6 machine class.

2015-11-04target-i386: fix pcmpxstrx equal-ordered (strstr) modePaolo Bonzini
In this mode, referring an invalid element of the source forces the result to false (table 4-7, last column) but referring an invalid element of the destination forces the result to true, so the outer loop should still be run even if some elements of the destination will be invalid. They will be avoided in the inner loop, which correctly bounds "i" to validd, but they will still contribute to a positive outcome of the search. This fixes tst_strstr in glibc 2.17.

The patch introduces qemu_set_handle_nonoblocking, the local analog of qemu_set_nonblock for HANDLES.

Because of the patch 3ea3b7fa9af067982f34b of kvm, which introduces a lazy collapsing of small sptes into large sptes mechanism, now migration_end() is a time consuming operation because it calls memroy_global_dirty_log_stop(), which will trigger the dropping of small sptes operation and takes about dozens of milliseconds, so call migration_end() before all the vmsate data has already been transferred to the destination will prolong VM downtime. This operation should be deferred after all the data has been transferred to the destination. blk_mig_cleanup() can be deferred too.

2015-11-03armv7-m: Return DeviceState* from armv7m_init()Michael Davidsaver
Change armv7m_init to return the DeviceState* for the NVIC. This allows access to all GPIO blocks, not just the IRQ inputs. Move qdev_get_gpio_in() calls out of armv7m_init() into board code for stellaris and stm32f205 boards.

Add a Linux-specific pre-boot routine that matches the device- specific bootloaders behaviour. This is needed for modern Linux that expects the ARM PLL in SLCR to be a more even value (not 26).

2015-11-03arm: boot: Add board specific setup code APIPeter Crosthwaite
Add an API for boards to inject their own preboot software (or firmware) sequence. The software then returns to the bootloader via the link register. This allows boards to do their own little bits of firmware setup without needed to replace the bootloader completely (which is the requirement for existing firmware support). The blob is loaded by a callback if and only if doing a linux boot (similar to the existing write_secondary support). Rewrite the comment for the primary boot blob.

2015-11-03usb-host: fix usb3ep0quirk testGerd Hoffmann
usb->speed is the usb speed the device is actually running on in the qemu emulation (i.e. from the guests point of view). So when plugging usb3 devices into ehci hostadapter this is HIGH not SUPER. To figure whenever the host talks to the device with superspeed we have to check speedmask instead and see whenever the superspeed bit is set there.

2015-11-03ehci: clear suspend bit on detachGerd Hoffmann
When a device is detached, clear the suspend bit (PORTSC_SUSPEND) in the port status register. The specs are not *that* clear what is supposed to happen in case a suspended device is unplugged. But the enable bit (PORTSC_PED) is cleared, and the specs mention setting suspend with enable being unset is undefined behavior. So clearing them both looks reasonable, and it actually fixes the reported bug. https://bugzilla.redhat.com/show_bug.cgi?id=1268879 Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Message-id: 1445413462-18004-1-git-send-email-kraxel@redhat.com

commit e0d03b8ceb52 converted VNC startup to use SocketAddress, the interface socket_listen don't have a port_offset param, so we need to add the port offset (5900) to both 'port' and 'to' opts. currently only 'port' is added by offset.

2015-11-03vnc: allow fall back to RAW encodingPeter Lieven
I have observed that depending on the contents and the encoding it happens that sending data as RAW sometimes would take less space than the encoded data. This is especially the case for small updates or areas with high color images. If sending RAW encoded data is beneficial allow a fall back to RAW encoding for the framebuffer update.

2015-11-03ui/opengl: Reduce build required libraries for openglOGAWA Hirofumi
We now use epoxy to load opengl libraries. This means we don't need to link opengl libraries directly if interfaces handled by epoxy. With this, we just need epoxy headers and epoxy's *.so to build. Tested with epoxy-1.3.1. - sdl2/gtk/console egl stuff doesn't require other than epoxy - milkymist-tmu2 glx stuff doesn't require other than epoxy (lm32 test is limited, because can't find mmone-bios.bin, so just test to load libGL with "./lm32-softmmu/qemu-system-lm32 -M milkymist,accel=qtest") Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> [ lm32 tested by kraxel ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2015-11-03ui/curses: Fix pageup/pagedown on -cursesOGAWA Hirofumi
Current KEY_NPAGE/KEY_PPAGE handling is broken on -curses. Those uses "GREY", but "KEY_MASK" masked out "GREY". To fix, we have to use correct mask value - SCANCODE_KEYMASK. Then, this adds support of "shift + pageup/pagedown". With this, -curses mode can use scroll-up/down as usual like other display modes.
