The target endianness is not deduced anymore from the architecture name but asked directly to the guest, using a new qtest command: "endianness".

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

2015-05-22qtest: pre-buffer hex nibsJohn Snow1-4/+7
Instead of converting each byte one-at-a-time and then sending each byte over the wire, use sprintf() to pre-compute all of the hex nibs into a single buffer, then send the entire buffer all at once.

2015-05-22qtest: Add base64 encoded read/writeJohn Snow1-0/+69
For larger pieces of data that won't need to be debugged and viewing the hex nibbles is unlikely to be useful, we can encode data using base64 instead of encoding each byte as %02x, which leads to some space savings and faster reads/writes. For now, the default is left as hex nibbles in memwrite() and memread(). For the purposes of making qtest io easier to read and debug, some callers may want to specify using the old encoding format for small patches of data where the savings from base64 wouldn't be that profound. memwrite/memread use a data encoding that takes 2x the size of the original buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a decent amount of time and space.

2015-05-22qtest: allow arbitrarily long sendsJohn Snow1-18/+28
qtest currently has a static buffer of size 1024 that if we overflow, ignores the additional data silently which leads to hangs or stream failures. Use glib's string facilities to allow arbitrarily long data, but split this off into a new function, qtest_sendf. Static data can still be sent using qtest_send, which avoids the malloc/copy overhead.

Then covert the qemu_irq_intercept_out call to use qdev intercept version.

2014-10-04accel: Rename 'init' method to 'init_machine'Eduardo Habkost1-1/+1
Today, all accelerator init functions affect some global state: * tcg_init() calls tcg_exec_init() and affects globals such as tcg_tcx, page size globals, and possibly others; * kvm_init() changes the kvm_state global, cpu_interrupt_handler, and possibly others; * xen_init() changes the xen_xc global, and registers a change state handler. With the new accelerator QOM classes, initialization may now be split in two steps: * instance_init() will do basic initialization that doesn't affect any global state and don't need MachineState or MachineClass data. This will allow probing code to safely create multiple accelerator objects on the fly just for reporting host/accelerator capabilities, for example. * accel_init_machine()/init_machine() will save the accelerator object in MachineState, and do initialization steps which still affect global state, machine state, or that need data from MachineClass or MachineState. To clarify the difference between those two steps, rename init() to init_machine(). Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-12-10qtest: split configuration of qtest accelerator and chardevPaolo Bonzini1-10/+10
qtest uses the icount infrastructure to implement a test-driven vm_clock. This however is not necessary when using -qtest as a "probe" together with a normal TCG-, KVM- or Xen-based virtual machine. Hence, split out the call to configure_icount into a new function that is called only for "-machine accel=qtest"; and disable those commands when running with an accelerator other than qtest. This also fixes an assertion failure with "qemu-system-x86_64 -machine accel=qtest" but no -qtest option. This is a valid case, albeit somewhat weird; nothing will happen in the VM but you'll still be able to interact with the monitor or the GUI. Now that qtest_init is not limited to an int(void) function, change global variables that are not used outside qtest_init to arguments. And finally, cleanup useless parts of include/sysemu/qtest.h. The file is not used at all for user-only emulation, and qtest is not available on Win32 due to its usage of sigwait. Reported-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Michael S.
