This reverts commit 5018b3b4b7dc191d217ec60d2ac744cf7444e39f.
Let's help our future selves by making sure we don't introduce a bug
because of duplicating a network interface name or related bug to this
topic. Therefore, we can have multiple e1000 devices in the system now.
|
|
All DistinctNumerics are given an identifying tag, if the tag is
generated by the macro, print the alias instead of DistinctNumeric.
|
|
|
|
DistinctNumeric<T, ...> and some other types are very long, but the
template arguments provide no particular value, so just don't show them
|
|
|
|
Some folks on discord said adding another e1000 network adapter made it
so we don't have networking on the system anymore.
To fix this, we will use other unsupported PCI device instead.
|
|
Let's help our future selves by ensuring we have proper support for
secondary PCI buses always.

This allows a developer to easily dump a InlineLinkedList in the
debugger without having to manually running the list.
I needed this for a recent bug investigation in the Kernel.

This also optionally generates a test suite from the WebAssembly
testsuite, which can be enabled via passing `INCLUDE_WASM_SPEC_TESTS`
to cmake, which will generate test-wasm-compatible tests and the
required fixtures.
The generated directories are excluded from git since there's no point
in committing them.
|
|
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.

Don't pollute the source directory with generated code.
|
|
And use GENERATED_SOURCES (or add_dependencies) to make LibVT depend on
that target.
Fixes a FIXME.
|
|
For each .cpp file in the test suite data, there is a .ast file that
represents the "known good" baseline of the parser result.
Each .cpp file goes through the parser, and the result of
invoking `ASTNode::dump()` on the root node is compared to the
baseline to find regressions.
We also check that there were no parser errors when parsing the .cpp
files.
|
|
This is similar to the LibJS test data that resides in
/home/anon/js-tests.
It's more convenient than storing the test programs as raw strings
in the code.

As the parser now flattens out the instructions and inserts synthetic
nesting/structured instructions where needed, we can treat the whole
thing as a simple parsed bytecode stream.
This currently knows how to execute the following instructions:
- unreachable
- nop
- local.get
- local.set
- {i,f}{32,64}.const
- block
- loop
- if/else
- branch / branch_if
- i32_add
- i32_and/or/xor
- i32_ne
This also extends the 'wasm' utility to optionally execute the first
function in the module with optionally user-supplied arguments.

This had very bad interactions with ccache, often leading to rebuilds
with 100% cache misses, etc. Ali says it wasn't that big of a speedup
in the end anyway, so let's not bother with it.
We can always bring it back in the future if it seems like a good idea.

Fixes #7172.

As we removed the support of VBE modesetting that was done by GRUB early
on boot, we need to determine if we can modeset the resolution with our
drivers, and if not, we should enable text mode and ensure that
SystemServer knows about it too.
Also, SystemServer should first check if there's a framebuffer device
node, which is an indication that text mode was not even if it was
requested. Then, if it doesn't find it, it should check what boot_mode
argument the user specified (in case it's self-test). This way if we
try to use bochs-display device (which is not VGA compatible) and
request a text mode, it will not honor the request and will continue
with graphical mode.
Also try to print critical messages with mininum memory allocations
possible.
In LibVT, We make the implementation flexible for kernel-specific
methods that are implemented in ConsoleImpl class.
|
|
We simply modeset the resolution after determining the preferred
resolution after getting the EDID from the attached display.
|
|
Use the bochs-display device instead :)
|
|
This fixes a few compiler warnings and makes some variables const-ref
in preparation for the next commit which changes how ByteBuffer works.

This commit replaces the former, hand-written parser with a new one that
can be generated automatically according to a state change diagram.
The new `EscapeSequenceParser` class provides a more ergonomic interface
to dealing with escape sequences. This interface has been inspired by
Alacritty's [vte library](https://github.com/alacritty/vte/).
I tried to avoid changing the application logic inside the `Terminal`
class. While this code has not been thoroughly tested, I can't find
regressions in the basic command line utilities or `vttest`.
`Terminal` now displays nicer debug messages when it encounters an
unknown escape sequence. Defensive programming and bounds checks have
been added where we access parameters, and as a result, we can now
endure 4-5 seconds of `cat /dev/urandom`. :D
We generate EscapeSequenceStateMachine.h when building the in-kernel
LibVT, and we assume that the file is already in place when the userland
library is being built. This will probably cause problems later on, but
I can't find a way to do it nicely.

As of ~April 2021 the Meta/build-image-grub.sh script no longer works
for me (on Fedora 34) and fails with the following error:
/usr/sbin/grub2-install: warning: ../grub-core/partmap/msdos.c:403:
your core.img is unusually large. It won't fit in the embedding
area.
/usr/sbin/grub2-install: warning: Embedding is not possible. GRUB
can only be installed in this setup by using blocklists. However,
blocklists are UNRELIABLE and their use is discouraged..
/usr/sbin/grub2-install: error: will not proceed with blocklists.
Changing the size of the boot partition from 32 kiB to 1 MiB (2048
sectors) fixes the issue. This is also described in the following Ubuntu
grub2 bug (as well as 40 duplicates!) from 2012, which suggests the same
fix: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1059827
The Arch Linux wiki also uses 1 MiB in their BIOS/MBR examples for
parted: https://wiki.archlinux.org/title/Parted
I'm not sure why this suddenly stopped working, however I was able to
boot with an image created with this change applied.

Ideally we would never allocate under a spinlock, as it has many
performance and potentially functionality (deadlock) pitfalls.
We violate that rule in many places today, but we need a tool to track
them all down and fix them. This change introduces a new macro option
named `KMALLOC_VERIFY_NO_SPINLOCK_HELD` which can catch these
situations at runtime via an assert.
|
|
Previously the CMake options for -fsanitize=address, thread and
undefined were gated behind clang, which was unecessary. Only
-fsanitize=fuzzer is clang-only.

Now that all of the medium icons pass this check, we can make it
FATAL_ERROR to stop any new violations from being checked in.
|
|
Since the operations are already complicated and will become even more
so soon, let's split them into their own files. We can also integrate
the NumberTheory operations that would better fit there into this class
as well.
This commit doesn't change behaviors, but moves the allocation of some
variables into caller classes.
|
|
Make messages which should be fatal, actually fail the build.
- FATAL is not a valid mode keyword. The full list is available in the
docs: https://cmake.org/cmake/help/v3.19/command/message.html
- SEND_ERROR doesn't immediately stop processing, FATAL_ERROR does.
We should immediately stop if the Toolchain is not present.
- The app icon size validation was just a WARNING that is easy to
overlook. We should promote it to a FATAL_ERROR so that people will
not overlook the issue when adding a new application. We can only make
the small icon message FATAL_ERROR, as there is currently one
violation of the medium app icon validation.

This commit introduces the ability to parse the document catalog dict,
as well as the page tree and individual pages. Pages obviously aren't
fully parsed, as we won't care about most of the fields until we
start actually rendering PDFs.
One of the primary benefits of the PDF format is laziness. PDFs are
not meant to be parsed all at once, and the same is true for pages.
When a Document is constructed, it builds a map of page number to
object index, but it does not fetch and parse any of the pages. A page
is only parsed when a caller requests that particular page (and is
cached going forwards).
Additionally, this commit also adds an object_cast function which
logs bad casts if DEBUG_PDF is set. Additionally, utility functions
were added to ArrayObject and DictObject to get all types of objects
from the collections to avoid having to manually cast.

If mounting disk image fails (e.g. fuse is not available on macos),
always try using genext2fs before giving up.

This can currently parse a really simple module.
Note that it cannot parse the DataCount section, and it's still missing
almost all of the instructions.
This commit also adds a 'wasm' test utility that tries to parse a given
webassembly binary file.
It currently does nothing but exit when the parse fails, but it's a
start :^)

What happens if one file defines DEBUG_SPAM, and another doesn't,
then we link them together and get ODR violations? -- @ADKaster
|
|
This currently (obviously) doesn't support any actual 3D hardware,
hence all calls are done via software rendering.
Note that any modern constructs such as shaders are unsupported,
as this driver only implements Fixed Function Pipeline functionality.
The library is split into a base GLContext interface and a software
based renderer implementation of said interface. The global glXXX
functions serve as an OpenGL compatible c-style interface to the
currently bound context instance.

Not sure how this didn't cause a build break when I originally
moved them in #6891. Better fix them now.
|
|
The json file was removed a while back, and now AK/Tests has been
moved to Tests/AK. So this is wrong and out of date in every way.
