2015-06-22qerror: Clean up QERR_ macros to expand into a single stringMarkus Armbruster4-9/+9
These macros expand into error class enumeration constant, comma, string. Unclean. Has been that way since commit 13f59ae. The error class is always ERROR_CLASS_GENERIC_ERROR since the previous commit. Clean up as follows: * Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and delete it from the QERR_ macro. No change after preprocessing. * Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into error_setg(...). Again, no change after preprocessing.

2015-06-19qom: Don't pass string table to object_get_enum() functionDaniel P. Berrange1-14/+8
Now that properties can be explicitly registered as an enum type, there is no need to pass the string table to the object_get_enum() function. The object property registration already has a pointer to the string table. In changing this method signature, the hostmem backend object has to be converted to use the new enum property registration code, which simplifies it somewhat. Signed-off-by: Daniel P.

2015-05-31Extend TPM TIS interface to support TPM 2Stefan Berger1-0/+14
Following the recent upgrade to version 1.3, extend the TPM TIS interface with capabilities introduced for support of a TPM 2. TPM TIS for TPM 2 introduced the following extensions beyond the TPM TIS 1.3 (used for TPM 1.2): - A new 32bit interface Id register was introduced. - New flags for the status (STS) register were defined. - New flags for the capability flags were defined. Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2 on the backend side. Support the old TPM TIS 1.3 configuration if a TPM 1.2 is being used. A subsequent patch will then determine which TPM version is being used in the backend. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Michael S.

2014-08-06backends: Introduce chr-testdevPaolo Bonzini2-1/+132
From: Paolo Bonzini <pbonzini@redhat.com> chr-testdev enables a virtio serial channel to be used for guest initiated qemu exits. hw/misc/debugexit already enables guest initiated qemu exits, but only for PC targets. chr-testdev supports any virtio-capable target. kvm-unit-tests/arm is already making use of this backend. Currently there is a single command implemented, "q". It takes a (prefix) argument for the exit code, thus an exit is implemented by writing, e.g. "1q", to the virtio-serial port. It can be used as: $QEMU ... \ -device virtio-serial-device \ -device virtserialport,chardev=ctd -chardev testdev,id=ctd or, use: $QEMU ... \ -device virtio-serial-device \ -device virtconsole,chardev=ctd -chardev testdev,id=ctd to bind it to virtio-serial port0.

2014-05-05qom: Clean up fragile use of error_is_set() in set() methodsMarkus Armbruster2-8/+14
Using error_is_set(ERRP) to find out whether a function failed is either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP may be null, because errors go undetected when it is. It's fragile when proving ERRP non-null involves a non-local argument. Else, it's unnecessarily opaque (see commit 84d18f0). I guess the error_is_set(errp) in the ObjectProperty set() methods are merely fragile right now, because I can't find a call chain that passes a null errp argument. Make the code more robust and more obviously correct: receive the error in a local variable, then propagate it through the parameter.

I've ported the SDL1.2 code over, and rewritten it to use the SDL2 interface. The biggest changes were in the input handling, where SDL2 has done a major overhaul, and I've had to include a generated translation file to get from SDL2 codes back to qemu compatible ones. I'm still not sure how the keyboard layout code works in qemu, so there may be further work if someone can point me a test case that works with SDL1.2 and doesn't with SDL2. Some SDL env vars we used to set are no longer used by SDL2, Windows, OSX support is untested, I don't think we can link to SDL1.2 and SDL2 at the same time, so I felt using --with-sdlabi=2.0 to select the new code should be fine, like how gtk does it. v1.1: fix keys in text console v1.2: fix shutdown, cleanups a bit of code, support ARGB cursor v2.0: merge the SDL multihead patch into this, g_new the number of consoles needed, wrap DCL inside per-console structure.

2013-06-10qemu-char: don't issue CHR_EVENT_OPEN in a BHMichael Roth2-2/+1
When CHR_EVENT_OPENED was initially added, it was CHR_EVENT_RESET, and it was issued as a bottom-half: 86e94dea5b740dad65446c857f6959eae43e0ba6 Which we basically used to print out a greeting/prompt for the monitor. AFAICT the only reason this was ever done in a BH was because in some cases we'd modify the chr_write handler for a new chardev backend *after* the site where we issued the reset (see: 86e94d:qemu_chr_open_stdio()) At some point this event was renamed to CHR_EVENT_OPENED, and we've maintained the use of this BH ever since. However, due to 9f939df955a4152aad69a19a77e0898631bb2c18, we schedule the BH via g_idle_add(), which is causing events to sometimes be delivered after we've already begun processing data from backends, leading to: known bugs: QMP: session negotation resets with OPENED event, in some cases this is causing new sessions to get sporadically reset potential bugs: hw/usb/redirect.c: can_read handler checks for dev->parser != NULL, which may be true if CLOSED BH has not been executed yet. In the past, OPENED quiesced outstanding CLOSED events prior to us reading client data. If it's delayed, our check may allow reads to occur even though we haven't processed the OPENED event yet, and when we do finally get the OPENED event, our state may get reset. qtest.c: can begin session before OPENED event is processed, leading to a spurious reset of the system and irq_levels gdbstub.c: may start a gdb session prior to the machine being paused To fix these, let's just drop the BH. Since the initial reasoning for using it still applies to an extent, work around that by deferring the delivery of CHR_EVENT_OPENED until after the chardevs have been fully initialized, toward the end of qmp_chardev_add() (or some cases, qemu_chr_new_from_opts()). This defers delivery long enough that we can be assured a CharDriverState is fully initialized before CHR_EVENT_OPENED is sent. Also, rather than requiring each chardev to do an explicit open, do it automatically, and allow the small few who don't desire such behavior to suppress the OPENED-on-init behavior by setting a 'explicit_be_open' flag. We additionally add missing OPENED events for stdio backends on w32, which were previously not being issued, causing us to not recieve the banner and initial prompts for qmp/hmp.

2013-04-15tpm: reorganize headers and split hardware partPaolo Bonzini1-1/+37
The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h.

2013-04-04qemu-char: Call fe_claim / fe_release when not using qdev chr propertiesHans de Goede1-0/+6
chardev-frontends need to explictly check, increase and decrement the avail_connections "property" of the chardev when they are not using a qdev-chardev-property for the chardev. This fixes things like: qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \ -mon chardev=foo Working, where they should fail. Most of the changes here are due to old hardware emulation code which is using serial_hds directly rather then a qdev-chardev-property.
