There was a frequently occurring pattern of "map this physical address
into kernel VM, then read from it, then unmap it again".
This new typed_map() encapsulates that logic by giving you back a
typed pointer to the kind of structure you're interested in accessing.
It returns a TypedMapping<T> that can be used mostly like a pointer.
When destroyed, the TypedMapping object will unmap the memory. :^)
If we don't support ACPI, just don't instantiate an ACPI parser.
This is way less confusing than having a special parser class whose
only purpose is to do nothing.
We now search for the RSDP in ACPI::initialize() instead of letting
the parser constructor do it. This allows us to defer the decision
to create a parser until we're sure we can make a useful one.
We already have "global" as a way to access the global object in js(1)
(both REPL and script mode). This replaces it with "globalThis", which
is available in all environments, not just js.
This is a stop-gap patch solution for the annoying problem of models
being bad at updating. At least the process table will retain your
selection in SystemMonitor now.
In order to complete a relative URL, we need a Document. Fix this by
giving XMLHttpRequest a pointer to its window object. Then we can go
from the window to the document, and then we're home free. :^)
This patch adds very basic XMLHttpRequest support to LibWeb. Here's an
example that currently works:
var callback = function() { alert(this.responseText); }
var xhr = new XMLHttpRequest();
xhr.addEventListener("load", callback);
xhr.open("GET", "http://serenityos.org/~kling/test/example.txt");
xhr.send();
There are many limitations and bugs, but it's pretty dang awesome that
we have XHR. :^)
`IRCChannelMemberListModel->nick_at` returns the nick name of a channel
member at the specified index.
`IRCClient->nick_without_prefix` returns a formatted nick name without
privilege prefix.
- Get rid of the PCI::Initializer object which was not serving any real
purpose or holding any data members.
- Move command line parsing from init to PCI::initialize().
Instead of nesting a bunch of heap allocations, just store them in
a simple HashMap<u16, MMIOSegment>.
Also fix a bunch of double hash lookups like this:
ASSERT(map.contains(key));
auto thing = map.get(key).value();
They now look like this instead:
auto thing = map.get(key);
ASSERT(thing.has_value());
- Make things const when they don't need to be non-const.
- Don't return AK::String when it's always a string literal anyway.
- Remove excessive get_ prefixes per coding style.
The PCI access layer was composed of a bunch of virtual functions that
did nothing but call other virtual functions. The first layer was never
overridden so there was no need for them to be virtual.
This patch removes the indirection and moves logic from PCI::Access
down into the various PCI::get_foo() helpers that were the sole users.
- If there is no VMWare backdoor, don't allocate memory for it.
- Remove the "unsupported" state, instead just don't instantiate.
- Move the command-line parsing from init to the driver.
- Move mouse packet reception from PS2MouseDevice to VMWareBackdoor.
The purpose of init() is to get multi-tasking up and running. We don't
want to do anything in init() that doesn't advance that goal.
This patch moves some things from init() to init_stage2(), and adds a
comment block explaining the split.
Many other parsers call it with this name.
Also Type can be confusing in this context since the DeclarationType is
not the type (number, string, etc.) of the variables that are being
declared by the VariableDeclaration.
Some IRC clients use /hop to part and re-join a channel; however this
can be confused with granting half-op (+h) channel privileges to a user.
The general convention used by other IRC clients is /cycle.
