2021-09-10bsd-user: Add target_os_user.h to capture the user/kernel structuresWarner Losh1-0/+427

target_reg_t is the normal register. target_fpreg_t is the floating point registers. target_copy_regs copies the registers out of CPU context for things like core dumps.

Create thread_os_thread.h to hold the os specific parts of the thread and threat manipulation routines.

FreeBSD doesn't do AT_HWCAP, so remove that code. Linux does, and this code came from there. These changes are all interrelated and could be brokend down, but seem to represent a reviewable changeset since most of the change is boiler plate.

2021-09-06qemu-sockets: fix unix socket path copy (again)Michael Tokarev1-8/+5
Commit 4cfd970ec188558daa6214f26203fe553fb1e01f added an assert which ensures the path within an address of a unix socket returned from the kernel is at least one byte and does not exceed sun_path buffer. Both of this constraints are wrong: A unix socket can be unnamed, in this case the path is completely empty (not even \0) And some implementations (notable linux) can add extra trailing byte (\0) _after_ the sun_path buffer if we passed buffer larger than it (and we do). So remove the assertion (since it causes real-life breakage) but at the same time fix the usage of sun_path. Namely, we should not access sun_path[0] if kernel did not return it at all (this is the case for unnamed sockets), and use the returned salen when copyig actual path as an upper constraint for the amount of bytes to copy - this will ensure we wont exceed the information provided by the kernel, regardless whenever there is a trailing \0 or not. This also helps with unnamed sockets. Note the case of abstract socket, the sun_path is actually a blob and can contain \0 characters, - it should not be passed to g_strndup and the like, it should be accessed by memcpy-like functions.

It's not that much complicated to type "-display sdl" or "-display curses", so we should not clutter our main option name space with such simple wrapper options and rather present the users with a concise interface instead.

The alt_grab and ctrl_grab parameter of the -display sdl option prevent the QAPIfication of the "sdl" part of the -display option, so we should eventually remove them. And since this feature is also rather niche anyway, we should not clutter the top-level option list with these, so let's also deprecate the "-alt-grab" and the "-ctrl-grab" options while we're at it. Once the deprecation period of "alt_grab" and "ctrl_grab" is over, we then can finally switch the -display sdl option to use QAPI internally, too.

2021-09-06softmmu/vl: Add a "grab-mod" parameter to the -display sdl optionThomas Huth2-4/+17
The -display sdl option is not using QAPI internally yet, and uses hand- crafted parsing instead (see parse_display() in vl.c), which is quite ugly, since most of the other code is using the QAPIfied DisplayOption already. Unfortunately, the "alt_grab" and "ctrl_grab" use underscores in their names which has recently been forbidden in new QAPI code, so a straight conversion is not possible. While we could add some exceptions to the QAPI schema parser for this, the way these parameters have been designed was maybe a bad idea anyway: First, it's not possible to enable both parameters at the same time, thus instead of two boolean parameters it would be better to have only one multi-choice parameter instead. Second, the naming is also somewhat unfortunate since the "alt_grab" parameter is not about the ALT key, but rather about the left SHIFT key that has to be used additionally when the parameter is enabled. So instead of trying to QAPIfy "alt_grab" and "ctrl_grab", let's rather introduce an alternative to these parameters instead, a new parameter called "grab-mod" which can either be set to "lshift-lctrl-lalt" or to "rctrl". In case we ever want to support additional modes later, we can then also simply extend the list of supported strings here.

2021-09-06meson.build: Fix the check for a usable libfdtThomas Huth1-0/+1
The check for libfdt currently has a flaw: If there is a system libfdt, the meson.build code initialized the fdt variable with fdt = cc.find_library(...). However, if this libfdt is too old and there is no internal dtc module available, it continues with "fdt" pointing to the old and unusable version. The check later in the file that tries to detect whether libfdt is necessary then fails to trigger: if not fdt.found() and fdt_required.length() > 0 error('fdt not available but required by targets ' + ', '.join(fdt_required)) endif The build fails then during compilation instead, which is of course bad since this is quite confusing and already wasted quite some time of the user. Thus if libfdt is not usable, we should unset the "fdt" variable immediately again, so that the build already fails during the configuration phase.

2021-09-06docs: add definitions of terms for CI/testingWillian Rampazzo2-0/+122
To understand the current state of QEMU CI/testing and have a base to discuss the plans for the future, it is important to define some usual terms. This patch defines the terms for "Automated tests", "Unit testing", "Functional testing", "System testing", "Flaky tests", "Gating", and "Continuous Integration".

2021-09-04vhost-vdpa: remove the unncessary queue_index assignmentJason Wang1-1/+0
