2020-09-01meson: use pkg-config method to find dependenciesPaolo Bonzini2-17/+18
We do not need to ask cmake for the dependencies, so just use the pkg-config mechanism. Keep "auto" for SDL so that it tries using sdl-config too. The documentation is adjusted to use SDL2_image as the example, rather than SDL which does not use the "pkg-config" method. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-09-01configure: do not include ${prefix} in firmwarepathPaolo Bonzini1-1/+1

2020-09-01meson: add pixman dependency to UI modulesPaolo Bonzini1-3/+3
Pixman used to be included directly in QEMU_CFLAGS and therefore the include path was added to every compiler invocation. Now that (just like basically everything else) it is a separate dependency, we need to add it to all build target, especially UI modules that need it due to their including ui/console.h.

2020-09-01meson: use meson mandir instead of qemu_mandirMarc-André Lureau2-3/+2
When cross-compiling, by default qemu_mandir is 'c:\Program Files\QEMU', which is not recognized as being an absolute path, and meson will end up adding the prefix again.

2020-09-01meson: move zlib detection to mesonPaolo Bonzini2-36/+2
Meson includes the same logic that tries to look for -lz if pkg-config (and cmake) cannot find zlib. The undocumented --disable-zlib-test option becomes a no-op. There is still an instance of "-lz" in the LIBS directory. It will go away as soon as tests are converted to meson, because the zlib dependency does not propagate from libblock.fa to the Makefile-build unit tests.

2020-08-31hw/usb: Add U2F device autoscan to passthru modeCésar Belley3-14/+110
This patch adds an autoscan to let u2f-passthru choose the first U2F device it finds. The autoscan is performed using libudev with an enumeration of all the hidraw devices present on the host. The first device which happens to be a U2F device is taken to do the passtru.

2020-08-31hw/usb: Add U2F key emulated modeCésar Belley1-0/+405
This patch adds the U2F key emulated mode. The emulated mode consists of completely emulating the behavior of a U2F device through software part. Libu2f-emu is used for that. The emulated mode is associated with a device inheriting from u2f-key base. To work, an emulated U2F device must have differents elements which can be given in different ways. This is detailed in docs/u2f.txt. The Ephemeral one is the simplest way to configure, it lets the device generate all the elements it needs for a single use of the lifetime of the device: qemu -usb -device u2f-emulated For more information about libu2f-emu see this page: https://github.com/MattGorko/libu2f-emu.

2020-08-31hw/usb: Add U2F key passthru modeCésar Belley1-0/+423
This patch adds the U2F key pass-through mode. The pass-through mode consists of passing all requests made from the guest to the physical security key connected to the host machine and vice versa. In addition, the dedicated pass-through allows to have a U2F security key shared on several guests which is not possible with a simple host device assignment pass-through. The pass-through mode is associated with a device inheriting from u2f-key base. To work, it needs the path to a U2F hidraw, obtained from the Qemu command line, and passed by the user: qemu -usb -device u2f-passthru,hidraw=/dev/hidrawX Autoscan and U2F compatibility checking features are given at the end of the patch series.

2020-08-31hw/usb: Add U2F key base class implementationCésar Belley1-0/+352
This patch adds the U2F key base class implementation. The U2F key base mainly takes care of the HID interfacing with guest. On the one hand, it retrieves the guest U2FHID packets and transmits them to the variant associated according to the mode: pass-through or emulated. On the other hand, it provides the public API used by its variants to send U2FHID packets to the guest.

2020-08-28softfloat: Define operations for bfloat16LIU Zhiwei3-0/+211
This patch implements operations for bfloat16 except conversion and some misc operations. We also add FloatFmt and pack/unpack interfaces for bfloat16. As they are both static fields, we can't make a sperate patch for them.
