2014-12-14target-i386: fix icount processing for repz instructionsPavel Dovgalyuk1-2/+14
TCG generates optimized code for i386 repz instructions in single step mode. It means that when ecx becomes 0, execution of the string instruction breaks immediately without an additional iteration for ecx==0 (which will only check ecx and set the flags). Omitting this iteration leads to different instructions counting in singlestep mode and in normal execution. This patch disables optimization of this last iteration for icount mode which should be deterministic. v2: inverted the condition and formatted the comment Signed-off-by: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru> Signed-off-by: Richard Henderson <rth@twiddle.net>

Avoid that unplug submits requests when io_submit reported that it couldn't accept more; at the same time, try more io_submit calls if it could handle the whole set of requests that were passed, so that the "blocked" flag is reset as soon as possible. After the previous patch, laio_submit already tried to avoid submitting requests to a blocked queue, by comparing s->io_q.idx with "==" instead of the more natural ">=".

Test 039 used qemu-io -c abort for simulating a qemu crash; however, abort() generally results in a core dump and ulimit -c 0 is no reliable way of preventing that.

2014-12-12qemu-io: Add sigraise commandMax Reitz1-0/+46
abort() has the sometimes undesirable side-effect of generating a core dump. If that is not needed, SIGKILL has the same effect of abruptly crash qemu; without a core dump. Thus, -c abort is not always useful to simulate a qemu-io crash; therefore, this patch adds a new sigraise command which allows raising a signal.

2014-12-12block: vhdx - change .vhdx_create default block state to ZEROJeff Cody2-3/+9
The VHDX spec specifies that the default new block state is PAYLOAD_BLOCK_NOT_PRESENT for a dynamic VHDX image, and PAYLOAD_BLOCK_FULLY_PRESENT for a fixed VHDX image. However, in order to create space-efficient VHDX images with qemu-img convert, it is desirable to be able to set has_zero_init to true for VHDX. There is currently an option when creating VHDX images, to use block state ZERO for new blocks. However, this currently defaults to 'off'. In order to be able to eventually set has_zero_init to true for VHDX, this needs to default to 'on'. This patch changes the default to 'on', and provides some help information to warn against setting it to 'off' when using qemu-img convert. [Max Reitz pointed out that a full stop was missing at the end of the VHDX_BLOCK_OPT_ZERO option help text. I have added it. --Stefan] Signed-off-by: Jeff Cody <jcody@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Message-id: 85164899eacc86e150c3ceba793cf93b398dedd7.1418018421.git.jcody@redhat.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2014-12-12block: vhdx - update PAYLOAD_BLOCK_UNMAPPED value to match 1.00 specJeff Cody2-2/+4
The 0.95 VHDX spec defined PAYLOAD_BLOCK_UNMAPPED to be 5. The 1.00 VHDX spec redefines PAYLOAD_BLOCK_UNMAPPED to be 3 instead. The original value of 5 is now an undefined state in the spec, but it should be safe to treat it the same and return zeros for data read. This way, we can maintain compatibility with any images out in the wild that may have been created in accordance to the 0.95 spec.

If vmdk blindly tries to use path_combine() using bs->file->filename as the base file name, this will result in a bad error message for JSON file names when calling bdrv_open(). It is better to only try bs->file->exact_filename; if that is empty, bs->file->filename will be useless for path_combine() and an error should be emitted (containing bs->file->filename because desc_file_path (which is bs->file->exact_filename) is empty).

2014-12-11target-arm/kvm: make reg sync code common between kvm32/64Alex Bennée4-101/+137
Before we launch a guest we query KVM for the list of "co-processor" registers it knows about. This is used to synchronize system register state for the bulk of coprocessor/system registers. Move this code from the 32-bit specific vcpu init function into a common routine and call it also from the 64-bit vcpu init. This allows system registers to migrate correctly when using KVM, and also permits QEMU code to see the current KVM register state (which will be needed to support big-endian guests, since the virtio endianness callback must check for some system register settings). Since vcpu reset also has to sync registers, we move the 32 bit kvm_arm_reset_vcpu() into common code as well and share it with the 64 bit version. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> [PMM: just copy the 32-bit code rather than improving it along the way; don't share reg_syncs_via_tuple_list() between 32 and 64 bit; tweak function names; move reset] Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
