On Linux, due to the way we include SDL2 as a submodule, it makes it
difficult for us to specify which SDL_config.h we intended to include.
Before, CMake would default to the dummy one included with SDL and
ignore the generated one.
This tells CMake to use the generated one. In addition, we define
USING_GENERATED_CONFIG_H to throw an error in case the dummy config is
used by accident. Fixes Vulkan not working on Linux yuzu-cmd.
Currently Qt will download whether or not the target system supports the
package. Normally this isn't an issue since the package manager would
work out the dependencies for us, but in this case we must make sure
everything is in place before downloading the package.
This checks for the package's requirements, as well as tries to provides
hints as to what is required on some of the more cryptic dependencies.
yuzu requires CMake 3.15 yet find_program was using REQUIRED, which is
only available on 3.18 and later. Instead, we check for
"<VAR>-NOTFOUND".
In addition, check for additional requirements before building libusb or
FFmpeg with autotools. Otherwise, CMake configuration will pass yet
compilation will fail.
Delegates libusb external communication to externals/CMakeLists.txt
Ensures an interface library `usb` for every pathway
input_common just links to the `usb` library now
externals/libusb/CMakeLists.txt sets variables to override SDL2's libusb
finding
Other minor cleanup
Building libusb was also broken on GCC (and maybe Clang) on our
CMakeLists after upgrading to 1.0.24, but it was not being checked
because our 18.04 container had libusb installed on it.
This builds on the MinGW work from earlier and extends it to the rest of
the GNU toolchains. In addition we make use of pkg-config when present
to find libusb. pkg-config is preferrable because we can specify a
minimum required version.
After updating to 1.0.24, MinGW fails to build libusb as a result of
numerous errors. So we build libusb their way and let them update the
nontrivial stuff.
This only applies to MinGW: the old path is still in use for Linux
toolchains as well as MSVC.
This will dynamically link libusb, since I hit build errors with the old
way we used to resolve the conflict with SDL2.
CMAKE_DEPENDENT_OPTION takes a value argument, but as a macro function
it will read a variable name as the name and not the value. For
YUZU_USE_BUNDLED_QT, ensure that we are reading the value of MSVC. For
YUZU_ALLOW_SYSTEM_SDL2, CMAKE_DEPENDENT_OPTION is redundant here anyway
as we don't use that path on any toolchain by default.
If the local version of Qt is older than the minimum version required by
yuzu, download a pre-built binary package from yuzu-emu/ext-linux-bin
and build yuzu with it, instead.
This also requires linking yuzu to the correct libraries after building
it, and copying over the required binaries when building yuzu.
This sets the Qt requirement to 5.12, which is intentionally behind the
versions used by our toolchains since they are not all updated yet to
5.15.
Without the CONFIG option, find_package will perform Module search. On
at least Linux Mint 20 (I'm unable to reproduce this on CentOS and Arch
Linux), my guess is that this causes CMake to find "dirty" modules that
modify the configuration state despite the Boost version being too
low/absent.
Use CONFIG to put CMake into pure Config mode and avoid Module search.
Building SDL2 from externals is incompatible with Conan's version of
libiconv, a requirement of Conan's Boost package. Solution is to use the
same Boost package in use by the linux-fresh container. This tells CMake
to download boost_1_75_0.tar.xz from yuzu-emu/ext-linux-bin at CMake's
configuration step, much the same way Qt and FFmpeg are downloaded for
Windows.
Also makes DownloadExternals.cmake cross-platform. Although the CMake
code is not entirely specific to Linux, only Linux has Boost libraries
available at ext-linux-bin, whereas there is no equivalent Boost package
for Windows at ext-windows-bin. caveat emptor
If SDL2 is not found, the error is handled by falling back to externals.
No need spill the full warning at the find_package if it's going to be
handled later, so add QUIET to it.
Sets find_package(FFmpeg) to QUIET instead of REQUIRED. This allows
using the FFmpeg external in cases where there is no suitable installed
version of FFmpeg.
Also fixes a bug where multiple CMake configures causes FFmpeg_LIBRARIES
to concatenate on itself, producing cyclical dependencies. Unsets the
variable before building it in the foreach loop.
Fixes FFmpeg_INCLUDE_DIR not including the headers generated at run
time.
Forces using SDL 2.0.14. Upgrades the SDL external to that version. Adds
a message when switching to the external.
Fixes an error where input_common only links to SDL when SDL2_FOUND is
set, but externals/CMakeLists cannot set that variable to the required
scope. Switch to using ENABLE_SDL2, which we can use since we now
include the SDL source.
Since Bintray is (soon to be) no more, there needs to be a way to
acquire SDL2. Since 20.04's version is older than our minimum required
version (2.0.12), add it as an external.
- Bintray will be deprecated on May 1st 2021 (https://bintray.com/)
- We were previously using this for Qt (non-Windows) and SDL.
- I've moved to bundled SDL on Windows.
We had used conan for opus before, but there was a bug in the AVX detection.
However we still had the Findopus.cmake file within the repository, but not used.
This patch reenables the Findopus helper and prefer the system wide installation of opus.
Sets YUZU_USE_BUNDLED_FFMPEG as a CMake dependent option that is OFF on
Linux and ON for WIN32 targets. If FFmpeg is not found when
YUZU_USE_BUNDLED_FFMPEG is OFF, the bundled module/binaries are used
instead.
Reverts earlier changes to FindFFmpeg a bit, mostly to keep parity with
it's Citra version a bit. Now _FFmpeg_ALL_COMPONENTS lists all
components. We overwrite FFmpeg_LIBRARIES and FFmpeg_INCLUDE_DIR after
using the module.
Tells CMake to look for either nasm or yasm as it is required to build
FFmpeg. Avoids a compile-time error by checking for it during
configuration.
Adds a workaround for Ubuntu Bionic's old version of make not
communicating jobserver details properly.
Also renames related CMake variables to match both the Find*FFmpeg* and
variables defined within the file. Fixes odd errors produced by the old
FindFFmpeg.
Citra's FindFFmpeg is slightly modified here: adds Citra's copyright at
the beginning, renames FFmpeg_INCLUDES to FFmpeg_INCLUDE_DIR, disables a
few components in _FFmpeg_ALL_COMPONENTS, and adds the missing avutil
component to the comment above.
For Linux, instructs CMake to use the FFmpeg submodule in externals.
This is HEAVILY based on our usage of the late Unicorn. Minimal change
to MSVC as it uses the yuzu-emu/ext-windows-bin. MinGW now targets the
same ext-windows-bin libraries as MSVC for FFmpeg. Adds FFMPEG_LIBRARIES
to WIN32 and simplifies video_core/CMakeLists.txt a bit.
Update conan package version used for building.
A couple of new joystick-related functions might pose interest to yuzu's input system. Some sort of LED management have been added, but it doesn't seem to support leds used for player number indication JoyCons/ProCons use.
Boxcat is a web service but is still enabled if ENABLE_WEB_SERVICE is
disabled during the CMake stage, which causes compilation issues with
either missing headers or missing libraries.
This disables YUZU_ENABLE_BOXCAT regardless of the input if
ENABLE_WEB_SERVICE is disabled.
Addresses an issue with the two competing versions of Conan's Boost
package that are currently floating around.
Adds the Boost::context target only if it's recognized by CMake as a
target.
Fixes regression by 761206cf81, causing
yuzu to not build on Linux with any version of Boost except a cached
1.73 Conan version from before about a day ago.
Moves the Boost requirement out of the `REQUIRED_LIBS` psuedo-2D-array
for Conan to instead be manually configured, using Conan as a fallback
solution if the system does not meet our requirements.
Requires any update from the linux-fresh container in order to build.
**DO NOT MERGE** until someone with the MSVC toolchain can verify this
works there, too.
Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.
This also allows us to remove our dependency on Python.
This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library.
The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data.
To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library.
Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header.
Async GPU is not properly implemented at the moment.
