2016-03-22hw: explicitly include qemu-common.h and cpu.hPaolo Bonzini

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster
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. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-01-29ppc: Clean up includesPeter Maydell
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-6-git-send-email-peter.maydell@linaro.org
2015-07-07spapr-vty: Use TYPE_ definition instead of hardcodingDavid Gibson
There's a call to object_dynamic_cast() in spapr_vty which uses the type name "spapr-vty" directly, instead of the usual idiom of using the #defined TYPE_VIO_SPAPR_VTY_DEVICE. Fix it. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-07-07spapr_vty: lookup should only return valid VTY objectsDavid Gibson
If a guest passes the reg property of a valid VIO object that is not a VTY to either H_GET_TERM_CHAR or H_PUT_TERM_CHAR, QEMU hits a dynamic cast assertion and aborts. PAPR+ says "Hypervisor checks the termno parameter for validity against the Vterm IOA unit addresses assigned to the partition, else return H_Parameter." This patch adds a type check to ensure vty_lookup() either returns a pointer to a valid VTY object or NULL. H_GET_TERM_CHAR and H_PUT_TERM_CHAR will now return H_PARAMETER to the guest instead of crashing. The patch has no effect on the reg == 0 hack used to implement the RTAS call display-character.

2015-07-07spapr: Merge sPAPREnvironment into sPAPRMachineStateDavid Gibson
The code for -machine pseries maintains a global sPAPREnvironment structure which keeps track of general state information about the guest platform. This predates the existence of the MachineState structure, but performs basically the same function. Now that we have the generic MachineState, fold sPAPREnvironment into sPAPRMachineState, the pseries specific subclass of MachineState. This is mostly a matter of search and replace, although a few places which relied on the global spapr variable are changed to find the structure via qdev_get_machine().

2015-03-09spapr_vio: Convert to realize()Markus Armbruster
Bonus fix: always set an error on failure. Some failures were silent before, except for the generic error set by device_realize(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-06-16savevm: Remove all the unneeded version_minimum_id_old (ppc)Juan Quintela
After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2013-09-02pseries: Fix stalls on hypervisor virtual consoleAnton Blanchard
A number of users are reporting stalls when using the pseries hypervisor virtual console. A simple test case is to paste 15 or 17 characters at a time into the console. Pasting 15 characters at a time works fine but pasting 17 characters hangs for a random amount of time. Other activity (network, qemu monitor etc) unblocks it. If qemu-char tries to send more than 16 characters at once, vty_can_receive returns false. At this point we have to wait for the guest to consume that output. Everything is good so far. The problem occurs when the the guest does consume the output. We need to signal back to the qemu-char layer that we are ready for more input. Without this we block until something else kicks us (eg network activity). Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>

2013-04-26pseries: Convert VIO code to QOM style type safe(ish) castsDavid Gibson
Curerntly the pseries VIO device code contains quite a few explicit uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe, and not the conventional way of doing things in the QOM model. This patch converts the code to use the QOM convention of per-type macros to do verified casts with OBJECT_CHECK().
