<nowiki>*</nowiki> Unused

<nowiki>(1)</nowiki> Non-blocking: all other events preempt and block all the threads of their process until they are continued.

 

<nowiki>**</nowiki> Referenced but never used in practise

<nowiki>(3)</nowiki> Completely removed from the kernel, but referenced in DMNT. Stubbed relocation code (e.g., in Process9 and in PXI sysmodule) and even whole libraries (e.g., in PXI sysmodule's .rodata section) seem to indicate that Nintendo used dynamic libraries early in system development.

When calling svcDebugActiveProcess, an ATTACH PROCESS debug event is signaled, then ATTACH THREAD for each of its opened threads, then finally ATTACH BREAK.

| Used by kernelpanic. This makes core0 enter a WFI/B infinite loop. Threads that were created on core1 or core2 have their priority set to 0x3F, except if the thread was created on core1 and whose parent process (if any) has the "Runnable on sleep" [[NCCH/Extended_Header#ARM11_Kernel_Flags|ARM11 kernel flag]] set. Core1 threads with a priority of 0x40 without a parent process have their priority set to 0x3E.

Prior to first invoking this handler, the global variable holding <code>UNITINFO != 0</code> is true, and if there is no [[LCD_Registers#Fill_Color|LCD fill]] set at the time kernelpanic is called, kernelpanic fill the top screen with white (it does the same for the bottom screen if the current process is running under the APPLICATION memregion).

Prior to first invoking this handler, the global variable holding <code>UNITINFO != 0</code> is true, and if there is no [[LCD_Registers#Fill_Color|LCD fill]] set at the time kernelpanic is called, kernelpanic fills the top screen with red and the bottom screen with either yellow (if the current process was running under the APPLICATION memregion) or red.  

Before invoking this handler a second time, kernelpanic wait for the user to hold L+R+Start+Select down.

UNITINFO needs to be non-zero.  

UNITINFO needs to be non-zero for <code>what</code> 1 and 2.  

If <code>what</code> is 0 or any invalid value, nothing is done.  

If <code>what</code> is 0 or any invalid value, nothing is done.  

If it is 1, <code>val != 0</code> is written to the global variable enabling ERR:F-format register dumps on user-mode CPU/VFP exceptions (the VFP exception handler acts as if this variable was always true and works on retail environments). The user handler, stack pointer to use for exception handling, and pointer to use for the exception info structure are contiguously located in either the thread's TLS, or if the handler is NULL, in the main thread's TLS, at offset 0x40. If the specified stack pointer is 1, sp_usr - 0x5c is used instead; if the specified exception info buffer is 1, sp_usr - 0x5c is used instead, and if it is 0, <specified stack> - 0x5c is used (0x5c is the size of the exception info structure that is being pushed). Configured by NS on startup on dev-units (default being 0 on non-debugger/jtag units).

Configured by NS on startup on dev-units (default being 0 on non-debugger/jtag units) using the 0x000F0000 configuration block in the [[Config_Savegame|config savegame]].

If 3, this changes the scheduling/preemption mode (when no threads are being preempted, otherwise returns error 0xC8A01414), see [[KResourceLimit]] for more details.
