This reverts commit a808fff2ec.
I highly suspect the reason it was not working before was fixed in
017c5fc7d9, so the SB16 DMA can work even
if we initialize another E1000 network adapter.
QEMU appears to always relay absolute mouse coordinates relative to the
screen that the mouse is pointed to, without any way for us to know
what screen it was. So, when dealing with multiple displays force using
relative coordinates only.
This allows specifying how many screens we should use. This also then
only enables virtio-gpu if more than one display is requested.
This also adds an environment variable SERENITY_QEMU_DISPLAY_BACKEND
which allows overriding the default qemu display backend, as it may
not be available.
Multiboot only supports ELF32 executables. This changes the build
process to build an ELF32 executable which has a 32-bit entry point,
but consists of mostly 64-bit code.
`wasm-as` will do some semantic analysis on the modules, which is not
something we're looking for here.
Instead, use `wat2wasm` to generate the exact module.
Components are a group of build targets that can be built and installed
separately. Whether a component should be built can be configured with
CMake arguments: -DBUILD_<NAME>=ON|OFF, where <NAME> is the name of the
component (in all caps).
Components can be marked as REQUIRED if they're necessary for a
minimally functional base system or they can be marked as RECOMMENDED
if they're not strictly necessary but are useful for most users.
A component can have an optional description which isn't used by the
build system but may be useful for a configuration UI.
Components specify the TARGETS which should be built when the component
is enabled. They can also specify other components which they depend on
(with DEPENDS).
This also adds the BUILD_EVERYTHING CMake variable which lets the user
build all optional components. For now this defaults to ON to make the
transition to the components-based build system easier.
The list of components is exported as an INI file in the build directory
(e.g. Build/i686/components.ini).
Fixes#8048.
This commit adds a bunch of passes, the most interesting of which is a
pass that merges blocks together, and a pass that places blocks that
flow into each other next to each other, and a very simply pass that
removes duplicate basic blocks.
Note that this does not remove the jump at the end of each block in that
pass to avoid scope creep in the passes.
These are the actual structures that allow USB to work (i.e the ones
actually defined in the specification). This should provide us enough
of a baseline implementation that we can build on to support
different types of USB device.
These are pretty common on older LGA1366 & LGA1150 motherboards.
NOTE: Since the registers datasheets for all versions of the chip
besides versions 1 - 3 are still under NDAs i had to collect
several "magical vendor constants" from the *BSD driver and the
linux driver that i was not able to name verbosely, and as such
these are labeled with the comment "vendor magic values".
We call it E1000E, because the layout for these cards is somewhat not
the same like E1000 supported cards.
Also, this card supports advanced features that are not supported on
8254x cards.
This commit initializes the LibVideo library and implements parsing
basic Matroska container files. Currently, it will only parse audio
and video tracks.
Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.
