Previously LibLine accepted read callbacks while it was in the process
of reading input, this wasn't an issue as no async code was being
executed up until the Shell autocompletion came along.
Simply defer input processing while processing input to avoid causing
problems.
Fixes#13280.
We're now able to detect all the regular CPUID feature flags from
ECX/EDX for EAX=1 :^)
None of the new ones are being used for anything yet, but they will show
up in /proc/cpuinfo and subsequently lscpu and SystemMonitor.
Note that I replaced the periods from the SSE 4.1 and 4.2 instructions
with underscores, which matches the internal enum names, Linux's
/proc/cpuinfo and the general pattern of replacing special characters
with underscores to limit feature names to [a-z0-9_].
The enum member stringification has been moved to a new function for
better re-usability and to avoid cluttering up Processor.cpp.
This will make it possible to add many, many more CPU features - more
than the current limit 32 and later limit of 64 if we stick with an enum
class to be specific :^)
Checks of ECX go before EDX, and the bit indices are now ordered
properly. Additionally, handling of the EDX[11] bit has been moved into
a lambda function to keep the series of if statements neatly together.
All of this makes it *a lot* easier to follow along and compare the
implementation to the tables in the Intel manual, e.g. to find missing
checks.
This solves a problem where any non-trivial member in the global BSP
Processor instance would get re-initialized (improperly), losing data
that was already initialized earlier.
This is an enum-like type that works with arbitrary sized storage > u64,
which is the limit for a regular enum class - which limits it to 64
members when needing bit field behavior.

`fheroes2` is a recreation of HoMM2 game engine. This port is set with
`GET_HOMM2_DEMO=ON` for a free demo version to be automatically
downloaded and used, without requiring the user to provide game
resources from the original game.
Besides the provided patches, we set `CXXFLAGS="'-D_GNU_SOURCE'"` to
build the port, for SerenityOS' `LibC/endian.h` to provide required
endianness functions and constants.
**Considerations**:
* In-game custom cursor is not working, game logs show:
`Cursors are not currently supported` [0].
* Game is still unplayable, as it commonly raises a Kernel panic when
trying to start a new game (reported at SerenityOS/serenity#9401).

We now support generating top-left submatrices from a `Gfx::Matrix`
and we move the normal transformation calculation into
`SoftGPU::Device`. No functional changes.
We were normalizing data read from vertex attribute pointers based on
their usage, but there is nothing written about this behavior in the
spec or in man pages.
When we implement `glVertexAttribPointer` however, the user can
optionally enable normalization per vertex attribute pointer. This
refactors the `VertexAttribPointer` to have a `normalize` field so we
can support that future implementation.
We were transforming the vertices' normals twice (bug 1) and
normalizing them after lighting (bug 2). In the lighting code, we were
then diverting from the spec to deal with the normal situation, which
is now no longer needed.
This fixes the lighting of Tux in Tux Racer.
This patch reimplements inset property resolution based on the new
CSS Positioned Layout specification. Nothing should change for
left/right insets, but we gain support for top/bottom. :^)
Relatively positioned boxes should not affect the *layout* of their
siblings. So instead of applying relative inset as a layout-time
translation on the box, we now perform the adjustment at the paintable
level instead.
This makes position:relative actually work as expected, and exposes some
new bugs we need to take care of for Acid2. :^)
Expose the block size variable via a member function in the
AsyncBlockDeviceRequest so that the driver doesn't need to assume any
value such as 512 bytes.
The underlying driver does not need to recalculate the buffer size as
it is passed in the AsyncBlockDevice struct anyway. This also helps in
removing any assumptions of the underlying block size of the device.
Before this the flex layout didn't take into account the applied
borders or padding while laying out the items.
The child's top and left borders would get painted over the
parent's borders, also due to it not taking borders into account,
children with borders would overlap each other.
Due to it not taking padding into account, the children would get
drawn outside the parent element.
Some ISPs may MITM DNS requests coming from clients, changing the case
of domain name in response. LookupServer will refuse responses from
any DNS server in that case. This commit changes the behaviour to
perform a case-insensitive equality check.
If a C++ object already has a JS wrapper, we don't need to go through
the expensive type checks to figure out which kind of wrapper to create.
Instead, just return the wrapper we already have!
This gives a noticeable increase in smoothness on Acid3, where ~10% of
CPU time was previously spent doing RTTI type checks in wrap(). With
these changes, it's down to ~1%.
This reverts commit 2b2915656d.
While this adjustment is bogus, it is currently responsible for putting
CenterLeft aligned scalable text in the right position.
This is going to take a bunch of work to get right.
We've gotten ourselves into a bit of a mess by mixing pixel and point
sizes in multiple places. Step one towards getting out of this mess
is adding explicit accessors for the unit you're trying to fetch.
The core of the issue comes from bitmap fonts storing integer pixel
sizes and scaled (TTF) fonts storing float point sizes.
