2012-04-24Limit ptimer rate to something achievablePeter Chubb
If a guest sets very short timeouts, and asks for a timer to be reloaded on timeout, QEMU can go to 100%CPU utilisation and become unresponsive, as it is spending all its time generating timeout interrupts. On real hardware this doesn't matter, as the interrupts are just coalesced, and the effect is to have the interrupt asserted all the time. This patch is a band-aid, that prevents timeouts less than 10 microseconds from being set. 10 microseconds is a limit that was determined empirically on a variety of machines as the shortest that allowed QEMU to pick up a control-a c sequence to get at the monitor.

2012-04-24qemu-char: Fix crash when switching consolesStefan Weil
qemu-system-arm (and other system emulations) crashes with SDL when the user switches consoles (Alt-Ctrl-F4). We already check for NULL pointers in qemu_chr_fe_ioctl, qemu_chr_be_can_write and other functions, so do this also for s->chr_read in qemu_chr_be_write. This fixes the crash.

2012-04-24configure: add --with-confsuffix optionEduardo Habkost
This will allow the user to make Qemu use a different subdirectory name inside $datadir and $sysconfdir, instead of "/qemu". Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-04-24configure: change meaning of --datadir to Autoconf conventionEduardo Habkost
Autoconf uses --datadir for the /usr/share directory, not the program-specific subdirectory inside /usr/share. This changes configure to match autoconf behavior. Note that this will break compatibility with existing build scripts. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-04-24create_config: simplify prefix=* block, remove CONFIG_QEMU_PREFIXEduardo Habkost
As now that block handles only the prefix variable, the code can be much simpler. This also removes the CONFIG_QEMU_PREFIX define as it is not used by any C code. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-04-24create_config: remove *dir blockEduardo Habkost
Now only the qemu_*dir variables will become #defines. The other directory names aren't used by the C code. That means the following #defines won't be available in C code anymore: - CONFIG_QEMU_BINDIR - CONFIG_QEMU_LIBDIR - CONFIG_QEMU_INCLUDEDIR - CONFIG_QEMU_MANDIR - CONFIG_QEMU_SYSCONFDIR - CONFIG_QEMU_LIBEXECDIR The following #defines are going to be kept because they are handled by the qemu_* block on create_config: - CONFIG_QEMU_CONFDIR - CONFIG_QEMU_DATADIR - CONFIG_QEMU_DOCDIR This one will be kept because it is set directly by ./configure: - CONFIG_QEMU_HELPERDIR This patch keeps the 'prefix=*' (CONFIG_QEMU_PREFIX) pattern because other variables may use $prefix on their config-host.mak definitions. The remaining code will be simplified on a further patch. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-04-24config-host.mak: rename confdir to qemu_confdirEduardo Habkost
$confdir is a confusing name, as it's not clear if it's "the system config dir" or "the Qemus-specific directory inside the config dir". $qemu_confdir makes it more clear. The current C code that uses CONFIG_QEMU_CONFDIR should be safe, as now create_config generates the same #define name (CONFIG_QEMU_CONFDIR) for both "confdir" and "qemu_confdir" variables.

2012-04-24config-host.mak: rename datadir to qemu_datadirEduardo Habkost
Autoconf concept of "datadir" is supposed to be "$prefix/share", not "$prefix/share/PACKAGE", so using datadir for the Qemu-specific directory is confusing. The current C code that uses CONFIG_QEMU_DATADIR should be safe, as now create_config generates the same #define name (CONFIG_QEMU_DATADIR) for both "datadir" and "qemu_datadir" variables.

2012-04-24create_config: separate section for qemu_*dir variables (v2)Eduardo Habkost
The generic *dir section will eventually go away and be replaced with qemu_* section. By now, both sections will be kept, while the variables get renamed on config-host.mak. With this patch, a XXXdir variable will become a CONFIG_QEMU_XXXDIR define, and a qemu_XXXdir variable will become CONFIG_QEMU_XXXDIR as well (instead of becoming a CONFIG_QEMU_QEMU_XXXDIR define). Changes v1 -> v2: - Rebase on top of newer qemu.git changes, that changed "tr '[:lower:]' '[:upper:]'" to "LC_ALL=C tr '[a-z]' '[A-Z]'".

2012-04-24configure: rename $confdir to $qemu_confdirEduardo Habkost

2012-04-24configure: rename $docdir to $qemu_docdirEduardo Habkost
The autoconf "docdir" variable is used for the program-specific subdirectory, but anyway it's better to make it clear that the variable is used for the qemu-specific subdirectory path. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-04-24configure: rename $datadir to $qemu_datadirEduardo Habkost
The variable is used for the qemu-specific directory and has a different meaning of the autoconf "datadir" variable (that's used for the $prefix/share directory, not for $prefix/share/PACKAGE). This doesn't change behavior or interfaces, it's just an internal variable rename. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-04-23qmp: make block job command naming consistentStefan Hajnoczi
The block streaming and job commands used '_' instead of '-' for reasons of compatibility with libvirt, which already included support for the '_' naming. However, the semantics of block_job_cancel have changed and libvirt now needs to handle the new semantics. Since the old semantics were never in a QEMU release we can still rename the commands to use '-' instead of '_'. Libvirt is also happy because the new name can be used to distinguish QEMU binaries that support the latest block-job-cancel semantics from those that include a downstream block_job_cancel command. Therefore, let's apply the QAPI/QMP naming rules to the block streaming and job commands. QEMU 1.1 will be the first release with these commands so no upstream users can break. Note that HMP commands are left with '_' because that is the convention there.
