Anonymous and file-backed RAM allocation are now almost exactly the same.
Reduce code duplication by moving RAM mmap code out of oslib-posix.c and
exec.c.
Backports commit 794e8f301a17953efa78ab7538019ec43c59e82a from qemu
Move the muldiv64() function from qemu-common.h to host-utils.h.
This puts it together with all the other arithmetic functions
where we provide a version with __int128_t and a fallback
without, and allows headers which need muldiv64() to avoid
including qemu-common.h.
We don't include host-utils from qemu-common.h, to avoid dragging
more things into qemu-common.h than it already has; in practice
everywhere that needs muldiv64() can get it via qemu/timer.h.
Backports commit 49caffe0cc95a9d0dc344e3328be8197f3536cf8 from qemu
Add a header comment to osdep.h, explaining what the header is for
and some rules to avoid circular-include difficulties.
Backports commit 03557b9abaee78e9d1ef5cd236d32a7b3e75e6f8 from qemu
qemu-common.h has some system header includes and fixups for
things that might be missing. This is really an OS dependency
and belongs in osdep.h, so move it across.
Backports commit bfe7e449f14313f646da621288ca2fd12223414f from qemu
Rather than rolling custom concatenate-strings macros for the
QEMU_BUILD_BUG_ON macro to use, use the glue() macro we already
have (since it's now available to us in this header).
Backports commit 24134c4e9126bf505b612e901c63a102fc471083 from qemu
osdep.h has a few things which are really compiler specific;
move them to compiler.h, and include compiler.h from osdep.h.
Backports commit 4912086865083a008f4fb73173fd0ddf2206c4d9 from qemu
qemu_printf is an ancient remnant which has been a simple #define to
printf for over a decade, and is used in only a few places. Expand
it out in those places and remove the #define.
Backports commit 71baf787d8fa2a5d186f22d8154069fd212be37f from qemu
To prepare for a generic internal cipher API, move the
built-in AES implementation into the crypto/ directory
Backports commit 6f2945cde60545aae7f31ab9d5ef29531efbc94f from qemu
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.
Backports commit ddbb0d09661f5fce21b335ba9aea8202d189b98e from qemu
Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h
Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.
The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.
Backports commit fba0a593b2809ecdda68650952cf3d3332ac1990 from qemu
The new bitmap_test_and_clear_atomic() function clears a range and
returns whether or not the bits were set.
Backports commit 36546e5b803f6e363906607307f27c489441fd15 from qemu
Use atomic_or() for atomic bitmaps where several threads may set bits at
the same time. This avoids the race condition between threads loading
an element, bitwise ORing, and then storing the element.
When setting all bits in a word we can avoid atomic ops and instead just
use an smp_mb() at the end.
Most bitmap users don't need atomicity so introduce new functions.
Backports commit 9f02cfc84b85929947b32fe1674fbc6a429f332a from qemu
The documentation for sextract64() claims that the return type is
an int64_t, but the code itself disagrees. Fix the return type to
conform to the documentation and to bring it into line with
sextract32(), which returns int32_t.
