** KProcess::EnterUserException now sets address_key = (thread | 1) instead of thread.

*** This makes EnterUserException no longer a kernel waiter.

*** KScheduler::UpdateHighestThreads now checks if the top thread is the exception thread, and ignores the pinned thread if it is.

** All locations where KThread::m_num_kernel_waiters is changed now mark that a scheduler update is needed.

* KMemoryBlockManagerUpdater::Initialize has now been removed, rolled into KMemoryBlockManagerUpdater ctor.

Line 230:

Line 231:

* No longer uses CMIF for IPC, now uses new simpler/learner IPC protocol ("tipc", probably "tiny ipc").

** TIPC is implemented on top of HIPC svcs, same as CMIF was.

** Hacky/Hardcoded CMIF shim is provided for GetServiceHandle/RegisterClient, to avoid breaking games compiled with SDK < 12.x.

* sm: now has a max sessions of 69, up from 61.

** sm:m is maximum 1, for a total of 70.

===[[Bluetooth_Driver_services|bluetooth]]===

~~{Major changes~~, ~~TODO}~~

The IPC<>btstack code was rewritten. C++ objects with vfuncs are now used by commands, instead of the interface funcptr tables. Various structs/enums were updated/etc.

The funcs which were called via funcptrs from the HidMessageHandler thread for writing the various EventInfo state are now inlined.

The Adapter commands were updated, which in the process vulns were [[Switch_System_Flaws|fixed]].

[[Bluetooth_Driver_services#RespondToPinRequest|RespondToPinRequest]] now actually uses the input PIN instead of hard-coding it.

[[Bluetooth_Driver_services#StartInquiry|StartInquiry]] was updated.

System-setting "bluetooth_config!skip_boot" is now [[Bluetooth_Driver_services#IsManufacturingMode|handled]].

For more details, see [[Bluetooth_Driver_services|here]].

Support for bluetooth audio was added. Note however, that the audio-sysmodule still doesn't use the btdrv service.

===[[BTM_services|btm]]===

None of the new btdrv commands are used. [[Bluetooth_Driver_services#StartInquiry|StartInquiry]] with an user-specified service_mask is used, however it's unknown what triggers using this.

=== [[Applet_Manager_services|am]] ===
