2020-07-10qemu-option: Make functions taking Error ** return bool, not voidMarkus Armbruster3-49/+64
See recent commit "error: Document Error API usage rules" for rationale. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Message-Id: <20200707160613.848843-14-armbru@redhat.com>
2020-07-10qemu-option: Replace opt_set() by cleaner opt_validate()Markus Armbruster1-16/+19
opt_set() frees its argument @value on failure. Slightly unclean; functions ideally do nothing on failure. To tidy this up, move opt_create() from opt_set() into its callers, along with the cleanup. Rename opt_set() to opt_validate(), noting its similarity to qemu_opts_validate(). Drop redundant parameter @opts; use opt->opts instead.

2020-07-10qemu-option: Check return value instead of @err where convenientMarkus Armbruster5-22/+14
Convert uses like opts = qemu_opts_create(..., &err); if (err) { ... } to opts = qemu_opts_create(..., errp); if (!opts) { ... } Eliminate error_propagate() that are now unnecessary. Delete @err that are now unused. Note that we can't drop parallels_open()'s error_propagate() here. We continue to execute it even in the converted case. It's a no-op then: local_err is null.

2020-07-10error: Document Error API usage rulesMarkus Armbruster1-6/+46
This merely codifies existing practice, with one exception: the rule advising against returning void, where existing practice is mixed. When the Error API was created, we adopted the (unwritten) rule to return void when the function returns no useful value on success, unlike GError, which recommends to return true on success and false on error then. When a function returns a distinct error value, say false, a checked call that passes the error up looks like if (!frobnicate(..., errp)) { handle the error... } When it returns void, we need Error *err = NULL; frobnicate(..., &err); if (err) { handle the error... error_propagate(errp, err); } Not only is this more verbose, it also creates an Error object even when @errp is null, &error_abort or &error_fatal. People got tired of the additional boilerplate, and started to ignore the unwritten rule. The result is confusion among developers about the preferred usage. Make the rule advising against returning void official by putting it in writing. This will hopefully reduce confusion. Update the examples accordingly. The remainder of this series will update a substantial amount of code to honor the rule.

2020-07-07tracetool: work around ust <sys/sdt.h> include conflictStefan Hajnoczi1-0/+6
Both the dtrace and ust backends may include <sys/sdt.h> but LTTng Userspace Tracer 2.11 and later requires SDT_USE_VARIADIC to be defined before including the header file. This is a classic problem with C header files included from different parts of a program. If the same header is included twice within the same compilation unit then the first inclusion determines the macro environment. Work around this by defining SDT_USE_VARIADIC in the dtrace backend too. It doesn't hurt and fixes a missing STAP_PROBEV() compiler error when the ust backend is enabled together with the dtrace backend.

2020-07-07object: qom module supportGerd Hoffmann2-0/+26
Little helper function to load modules on demand. In most cases adding module loading support for devices and other objects is just s/object_class_by_name/module_object_class_by_name/ in the right spot.

2020-07-07module: qom module supportGerd Hoffmann2-0/+57
Add support for qom types provided by modules. For starters use a manually maintained list which maps qom type to module and prefix. Two load functions are added: One to load the module for a specific type, and one to load all modules (needed for object/device lists as printed by -- for example -- qemu -device help).

Currently we have 2 types of vhost backends in QEMU: vhost kernel and vhost-user. The above patch provides a generic device for vDPA purpose, this vDPA device exposes to user space a non-vendor-specific configuration interface for setting up a vhost HW accelerator, this patch set introduces a third vhost backend called vhost-vdpa based on the vDPA interface.

In commit a8d2532645cf5ce4 we cleaned up usage of the qemu-common.h header so that it was always included from .c files and never from other .h files. We missed adding it to net/tap-solaris.c (which previously was pulling it in via tap-int.h), which broke building on Solaris hosts.

2020-07-07util/qemu-option: Document the get_opt_value() functionPhilippe Mathieu-Daudé1-0/+13
Coverity noticed commit 950c4e6c94 introduced a dereference before null check in get_opt_value (CID1391003): In get_opt_value: All paths that lead to this null pointer comparison already dereference the pointer earlier (CWE-476) We fixed this in commit 6e3ad3f0e31, but relaxed the check in commit 0c2f6e7ee99 because "No callers of get_opt_value() pass in a NULL for the 'value' parameter". Since this function is publicly exposed, it risks new users to do the same error again. Avoid that documenting the 'value' argument must not be NULL.

2020-07-06softfloat,m68k: disable floatx80_invalid_encoding() for m68kLaurent Vivier1-0/+24
According to the comment, this definition of invalid encoding is given by intel developer's manual, and doesn't comply with 680x0 FPU. With m68k, the explicit integer bit can be zero in the case of: - zeros (exp == 0, mantissa == 0) - denormalized numbers (exp == 0, mantissa != 0) - unnormalized numbers (exp != 0, exp < 0x7FFF) - infinities (exp == 0x7FFF, mantissa == 0) - not-a-numbers (exp == 0x7FFF, mantissa != 0) For infinities and NaNs, the explicit integer bit can be either one or zero. The IEEE 754 standard does not define a zero integer bit. Such a number is an unnormalized number. Hardware does not directly support denormalized and unnormalized numbers, but implicitly supports them by trapping them as unimplemented data types, allowing efficient conversion in software. See "M68000 FAMILY PROGRAMMER’S REFERENCE MANUAL", "1.6 FLOATING-POINT DATA TYPES" We will implement in the m68k TCG emulator the FP_UNIMP exception to trap into the kernel to normalize the number. In case of linux-user, the number will be normalized by QEMU.

Otherwise the m68k_cpu_get_phys_page_debug() function can round to the wrong page causing incorrect lookups in gdbstub and various "Disassembler disagrees with translator over instruction decoding" warnings to appear at translation time.
