The script generated from QEMU_SRC/.travis.yml uses BUILD_DIR and SRC_DIR path relative to the current dir, unless these variables are exported in environment. Since commit 05790dafef1 BUILD_DIR is exported in the runner script, although SRC_DIR is not, so that make docker-travis fails becase the reference to source dir is wrong.

2019-03-21target/xtensa: fix break_dependency for repeated resourcesMax Filippov1-0/+17
break_dependency incorrectly handles the case of dependency on an opcode that references the same register multiple times. E.g. the following instruction is translated incorrectly: { or a2, a3, a3 ; or a3, a2, a2 } This happens because resource indices of both dependency graph nodes are incremented, and a copy for the second instance of the same register in the ending node is not done. Only increment resource index of the ending node of the dependency. Add test. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2019-03-20i386: Disable OSPKE on CPU model definitionsEduardo Habkost1-0/+33
Currently, the Cascadelake-Server, Icelake-Client, and Icelake-Server are always generating the following warning: qemu-system-x86_64: warning: \ host doesn't support requested feature: CPUID.07H:ECX [bit 4] This happens because OSPKE was never returned by GET_SUPPORTED_CPUID or x86_cpu_get_supported_feature_word(). OSPKE is a runtime flag automatically set by the KVM module or by TCG code, was always cleared by x86_cpu_filter_features(), and was not supposed to appear on the CPU model table. Remove the OSPKE flag from the CPU model table entries, to avoid the bogus warning and avoid returning invalid feature data on query-cpu-* QMP commands. As OSPKE was always cleared by x86_cpu_filter_features(), this won't have any guest-visible impact. Include a test case that should detect the problem if we introduce a similar bug again.

2019-03-19iotests: 153: Wait for an answer to QMP commandsSergio Lopez2-6/+12
There are various actions in this test that must be executed sequentially, as the result of it depends on the state triggered by the previous one. If the last argument of _send_qemu_cmd() is an empty string, it just sends the QMP commands without waiting for an answer. While unlikely, it may happen that the next action in the test gets invoked before QEMU processes the QMP request. This issue seems to be easier to reproduce on servers with limited resources or highly loaded. With this change, we wait for an answer on all _send_qemu_cmd() calls.

2019-03-12file-posix: Make auto-read-only dynamicKevin Wolf1-6/+6
Until now, with auto-read-only=on we tried to open the file read-write first and if that failed, read-only was tried. This is actually not good enough for libvirt, which gives QEMU SELinux permissions for read-write only as soon as it actually intends to write to the image. So we need to be able to switch between read-only and read-write at runtime. This patch makes auto-read-only dynamic, i.e. the file is opened read-only as long as no user of the node has requested write permissions, but it is automatically reopened read-write as soon as the first writer is attached. Conversely, if the last writer goes away, the file is reopened read-only again. bs->read_only is no longer set for auto-read-only=on files even if the file descriptor is opened read-only because it will be transparently upgraded as soon as a writer is attached. This changes the output of qemu-iotests 232. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2019-03-12file-posix: Fix bdrv_open_flags() for snapshot=onKevin Wolf3-0/+25
Using a different read-only setting for bs->open_flags than for the flags to the driver's open function is just inconsistent and a bad idea. After this patch, the temporary snapshot keeps being opened read-only if read-only=on,snapshot=on is passed. If we wanted to change this behaviour to make only the orginal image file read-only, but the temporary overlay read-write (as the comment in the removed code suggests), that change would have to be made in bdrv_temp_snapshot_options() (where the comment suggests otherwise). Addressing this inconsistency before introducing dynamic auto-read-only is important because otherwise we would immediately try to reopen the temporary overlay even though the file is already unlinked.

2019-03-12tests/tcg/cris: align mul operationsAlex Bennée1-0/+11
To avoid: Error: dangerous MULS/MULU location; give it higher alignment Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
2019-03-12tests/tcg/cris: comment out the ccs testAlex Bennée1-7/+7
Evidently upstream gcc doesn't like this opcode. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
2019-03-12tests/tcg: split cris tests into bare and libc directoriesAlex Bennée102-0/+0
Bare tests are standalone assembly tests that don't require linking to any libc and hence can be built with kernel only compilers. The libc tests need a compiler capable of building properly linked userspace binaries. As we don't have such a cross compiler at the moment we won't be building those tests.

2019-03-12tests/tcg/cris: cleanup sys.cAlex Bennée1-48/+52
This is a mini library which provides helper functions to the tests which are all currently written in assembly. A bunch of minor changes: - removed libc related headers (fedora-cris-cross is a system compiler) - re-organised the functions to avoid forward declarations - cleaned up brace usage - restored exit for _fail case - removed tabs and fixed indentation Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

2019-03-12tests/tcg/arm: add ARMv6-M UNDEFINED 32-bit instruction testStefan Hajnoczi3-0/+204
Test that 32-bit instructions declared UNDEFINED in the ARMv6-M Reference Manual really do raise an exception. Also test that the 6 32-bit instructions defined in the ARMv6-M Reference Manual do not raise an exception.

2019-03-12tests/tcg/mips: fix hello-mips compilationAlex Bennée2-8/+5
The compilation flags for proper building are in the source tree. We also fix exit to 0 so the result is counted as a success. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
2019-03-12tests/tcg: add gdb runner variantAlex Bennée1-0/+3
With this you can launch a test in gdb with: cd $(BUILD)/tests make -f $(SRC)/tests/tcg/Makefile gdb-$(TEST_NAME) Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
2019-03-12tests/tcg: split run-test into user and system variantsAlex Bennée1-2/+17
We can't rely on shell redirect magic to get things right so lets setup a common output chardev that is expecting to write to files. As we have split run-test up we might as well move the default monitor bits into the call. Finally a little make sophistry is required to correctly quote $(COMMA) and as we don't inherit common rules we have our own little copy here. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
2019-03-12tests/tcg: add QEMU_OPT option for test runnerAlex Bennée1-1/+4
