We don't need to specify all of the ARM interfaces explicitly.
|
|
The first word is just a padding byte, it's not an actual entry
instruction. Also renames the rest of the entries according to
SwitchBrew.
|
|
The padding after the magic signature value should be 12 bytes rather
than 28 bytes. The other 16 should be placed after the title ID pattern.

While partially correct, this service call allows the retrieved event to
be null, as it also uses the same handle to check if it was referring to
a Process instance. The previous two changes put the necessary machinery
in place to allow for this, so we can simply call those member functions
here and be done with it.
|
|
Process instances can be waited upon for state changes. This is also
utilized by svcResetSignal, which will be modified in an upcoming
change. This simply puts all of the WaitObject related machinery in
place.
|
|
svcResetSignal relies on the event instance to have already been
signaled before attempting to reset it. If this isn't the case, then an
error code has to be returned.

This function simply does a handle table lookup for a writable event
instance identified by the given handle value. If a writable event
cannot be found for the given handle, then an invalid handle error is
returned. If a writable event is found, then it simply signals the
event, as one would expect.
|
|
svcCreateEvent operates by creating both a readable and writable event
and then attempts to add both to the current process' handle table.
If adding either of the events to the handle table fails, then the
relevant error from the handle table is returned.
If adding the readable event after the writable event to the table
fails, then the writable event is removed from the handle table and the
relevant error from the handle table is returned.
Note that since we do not currently test resource limits, we don't check
the resource limit table yet.

kernel/object: Amend handle types to distinguish between readable and writable events
|

writable events
Two kernel object should absolutely never have the same handle ID type.
This can cause incorrect behavior when it comes to retrieving object
types from the handle table. In this case it allows converting a
WritableEvent into a ReadableEvent and vice-versa, which is undefined
behavior, since the object types are not the same.
This also corrects ClearEvent() to check both kernel types like the
kernel itself does.

Another hold-over from Citra.

Allows a process to register the resource limit as part of its handle
table.

Previously, ILibraryAppletAccessor would signal upon creation of any applet, but this is incorrect. A flag inside of the applet code determines whether or not creation should signal state change and swkbd happens to be one of these applets.

Similar to the NRO changes, we can also pass the process explicitly as a
parameter from Load instead of indirecting through the System class.
|
|
This simply acts as a forwarding function for the Load() function, so
this doesn't need to be directly exposed.
|
|
The path buffer is actually 0x301 (769) characters in length, with the
extra character being intended for the null-terminator.
|
|
Load() is already given the process instance as a parameter, so instead
of coupling the class to the System class, we can just forward that
parameter to LoadNro()

instance to act upon
The kernel uses the handle table of the current process to retrieve the
process that should be used to retrieve certain information. To someone
not familiar with the kernel, this might raise the question of "Ok,
sounds nice, but doesn't this make it impossible to retrieve information
about the current process?".
No, it doesn't, because HandleTable instances in the kernel have the
notion of a "pseudo-handle", where certain values allow the kernel to
lookup objects outside of a given handle table. Currently, there's only
a pseudo-handle for the current process (0xFFFF8001) and a pseudo-handle
for the current thread (0xFFFF8000), so to retrieve the current process,
one would just pass 0xFFFF8001 into svcGetInfo.
The lookup itself in the handle table would be something like:
template <typename T>
T* Lookup(Handle handle) {
if (handle == PSEUDO_HANDLE_CURRENT_PROCESS) {
return CurrentProcess();
}
if (handle == PSUEDO_HANDLE_CURRENT_THREAD) {
return CurrentThread();
}
return static_cast<T*>(&objects[handle]);
}
which, as is shown, allows accessing the current process or current
thread, even if those two objects aren't actually within the HandleTable
instance.
