This is no longer relevant for most users because due to an
unrelated change to Meta/run.sh the default display backend is now
SDL which does not exhibit this problem.
The x86_64 QEMU binary supports both i386 as well as x86_64 guests.
By using the x86_64 binary users won't have to change anything when
switching between i386 and x86_64 builds.
People are commonly asking about a package manager in
serenity. This patch adds an answer the FAQ, explaining
why there is no need for packages as well as different
possible ways to add or remove software installed on the
system.
This workaround disables the in-kernel interrupt controller.
This impacts the VM performance and should probably be removed
when the workaround is no longer needed.
This workaround was posed by stelar7.
See #7523
Mention the "Open Project Wizard" where you can set
the CMake options before making the cache.
Remind users to use the "Default" build type
and to build the Toolchain so CMake does not complain.
Because of the added complexity of *non-throwing* `new`, helper methods
for correctly constructing smart pointers were added in a previous
commit. This commit changes the documentation to recommend using these,
and adds examples to aid in correctly determining when to use
non-throwing new when manually creating smart pointers.
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.
PR #7970 added a line clarifying the requirement for QEMU 5.
Unfortunately, this location this line was added changed the meaning
of the following line, referencing the availability of GCC in Ubuntu
20.04.
QEMU 5 is not available in Ubuntu 20.04, so this change is incorrect,
as well as misleading.
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".
This is a fairly small change; removed the statement "Pointer and
reference types in C++ code" as it does not provide any additional
knowledge that contributors are or will be aware of after further
reading into the "Pointers and References" section. It seems
unnecessary and redundant given the sentence adjacent to it.
Unfortunately we cannot enforce this with clang-format yet, as that
feature is not available. Until then, let's try to write new code
with this in mind, and convert old code as we go.
This option replaces the use of ENABLE_ALL_THE_DEBUG_MACROS in CI runs,
and enables all debug options that might be broken by developers
unintentionally that are only used in specific debugging situations.
When debugging kernel code, it's necessary to set extra flags. Normal
advice is to set -ggdb3. Sometimes that still doesn't provide enough
debugging information for complex functions that still get optimized.
Compiling with -Og gives the best optimizations for debugging, but can
sometimes be broken by changes that are innocuous when the compiler gets
more of a chance to look at them. The new CMake option enables both
compile options for kernel code.
This only tests "can it be parsed", but the goal of this commit is to
provide a test framework that can be built upon :)
The conformance tests are downloaded, compiled* and installed only if
the INCLUDE_WASM_SPEC_TESTS cmake option is enabled.
(*) Since we do not yet have a wast parser, the compilation is delegated
to an external tool from binaryen, `wasm-as`, which is required for the
test suite download/install to succeed.
This *does* run the tests in CI, but it currently does not include the
spec conformance tests.
This was hiding on the serenityos.org website previously, where not
many people found it. Let's put it in a more natural location, and
also make sure to link to it from the README.
The current ProtocolServer was really only used for requests, and with
the recent introduction of the WebSocket service, long-lasting
connections with another server are not part of it. To better reflect
this, this commit renames it to RequestServer.
This commit also changes the existing 'protocol' portal to 'request',
the existing 'protocol' user and group to 'request', and most mentions
of the 'download' aspect of the request to 'request' when relevant, to
make everything consistent across the system.
Note that LibProtocol still exists as-is, but the more generic Client
class and the more specific Download class have both been renamed to a
more accurate RequestClient and Request to match the new names.
This commit only change names, not behaviors.

This command line flag can be used to disable VirtIO support on
certain configurations (native windows) where interfacing with
virtio devices can cause qemu to freeze.
Helps with bare metal debugging, as we can't be sure our implementation
will work with a given machine.
As reported by someone on Discord, their machine hangs when we attempt
the dummy transfer.
We do support AHCI now, but the implementation could be incomplete for
some chipsets.
Also, we should write the acronym "Non-volatile Memory Express" as
NVMe. not NVME.
If you don't need/want to use Fuse+ex2 then half of the existing
install command is unnecessary, and it's hard to pick out which you
do and don't need to, for example, build Lagom. This makes it clear
which commands you can skip if you don't need ex2 support.
- Fix headings
- Consistent & more accurate code block language specifiers
- Add some newlines where appropriate
- Remove the strange "run ninja but actually you don't have to run ninja
as ninja install takes care of that" part
- Don't repeat specific build commands in "Ports" section
- Reword "Keymap" section to more generic "Customize disk image"
The QEMU's `--accel hvf` command was recently enabled in the `run.sh`
script, but it sadly doesn't work on macOS Big Sur: you need to first
sign your code by adding an `entitlements.xml` file and running a
simple command.
Including 'Build/' is unfortunate, but this seems to be what everyone does,
short of creating a symlink/hardlink from /AK/Debug.h to /Build/AK/Debug.h.
This feels like a crutch, but it's a better crutch than having a workaround
that could easily break or corrupt commits (i.e., the symlinks).
I just ran through successfully building and running SerenityOS under
macOS. I ran into two main things that I struggled with, which were
- properly enabling osxfuse (through System Preferences)
- running the suggested command about compiler versions in such a way
that would be compatible with Ninja (as it turns out, I just needed
to add `-G Ninja` to the command)
This commit clarifies those things for anyone who may follow
