| * s390x: replace cpu_s390x_init() with cpu_generic_init()Igor Mammedov2017-09-013-16/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cpu_s390x_init() is used only *-user targets indirectly via cpu_init() macro and has a hack to assign ids to created cpus (I'm not sure if 'id' really matters to *-user emulation). So to on safe side, instead of having custom wrapper to do numbering replace it with cpu_generic_init() and use S390CPUClass::next_cpu_id which could serve the same purpose as static variable and move cpu->id initialization to s390_cpu_initfn for CONFIG_USER_ONLY use-case. PS: ifdef is ugly but it allows us to hide s390x detail that isn't set by *-user targets and reuse generic cpu creation utility for btoh machine and user emulation.

| * sparc: make cpu feature parsing property basedIgor Mammedov2017-09-011-133/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with features converted to properties we can use the same approach as x86 for features parsing and drop legacy approach that manipulated CPU instance directly. New sparc_cpu_parse_features() will allow only +-feat and explicitly disable feat=on|off syntax for now. With that in place and sparc_cpu_parse_features() providing generic CPUClass::parse_features callback, the cpu_sparc_init() will do the same job as cpu_generic_init() so replace content of cpu_sparc_init() with it.

| * sparc: move adhoc CPUSPARCState initialization to realize timeIgor Mammedov2017-09-011-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPARCCPU::env was initialized from previously set properties (with help of sparc_cpu_parse_features) in cpu_sparc_register(). However there is not reason to keep it there as this task is typically done at realize time. So move post properties initialization into sparc_cpu_realizefn, which brings cpu_sparc_init() closer to cpu_generic_init().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPARC is the last target that uses legacy way of parsing and initializing cpu features, drop legacy approach and convert features to properties so that SPARC could as minimum benefit from generic cpu_generic_init(), common with x86 +-feat parser PS: the main purpose is to remove legacy way of cpu creation as a blocker for unifying cpu creation code across targets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | since commit ( 9262685b cpu: Factor out cpu_generic_init() ) features parsed by it were truncated only to the 1st feature after CPU name due to fact that featurestr = strtok(NULL, ","); cc->parse_features(cpu, featurestr, &err); would extract exactly one feature and parse_features() callback would parse it and only it leaving the rest of features ignored. Reuse approach from x86 custom impl. i.e. replace strtok() token parsing with g_strsplit(), which would split feature string in 2 parts name and features list and pass the later to parse_features() callback.

| * | qcow2: allocate cluster_cache/cluster_data on demandStefan Hajnoczi2017-08-302-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most qcow2 files are uncompressed so it is wasteful to allocate (32 + 1) * cluster_size + 512 bytes upfront. Allocate s->cluster_cache and s->cluster_data when the first read operation is performance on a compressed cluster. The buffers are freed in .bdrv_close(). .bdrv_open() no longer has any code paths that can allocate these buffers, so remove the free functions in the error code path. This patch can result in significant memory savings when many qcow2 disks are attached or backing file chains are long: Before 12.81% (1,023,193,088B) After 5.36% (393,893,888B) Reported-by: Alexey Kardashevskiy <aik@ozlabs.ru> Tested-by: Alexey Kardashevskiy <aik@ozlabs.ru> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-id: 20170821135530.32344-1-stefanha@redhat.com Cc: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

| * | scripts: add argparse module for Python 2.6 compatibilityStefan Hajnoczi2017-08-302-0/+2676
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The minimum Python version supported by QEMU is 2.6. The argparse standard library module was only added in Python 2.7. Many scripts would like to use argparse because it supports command-line sub-commands. This patch adds argparse. See the top of argparse.py for details. Suggested-by: Daniel P.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a few cases which we're passing an Error pointer to a function only to discard it immediately afterwards without checking it. In these cases we can simply remove the variable and pass NULL instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If QEMU is running on a system that's out of memory and mmap() fails, QEMU aborts with no error message at all, making it hard to debug the reason for the failure. Add perror() calls that will print error information before aborting.
