previously only NoThread was returnable. +switch_count == idle_count + 1 implies that the switch to GetRunningThreadInfo() happened from idle thread, so ResultNoThread is returned exactly when the running thread was the idle thread. +Otherwise, if a thread other than the idle thread was the running thread, UnknownThread is returned. +KSchedulerLock::Lock() now always increments count, instead of setting count = 1 when the lock owner is not the current thread. +Note: Several KScheduler functions have big assembly changes, but this appears to be pure compiler optimization changes with no semantic differences. +KProcess had the creation time member deleted. +A new KPageTable::Operate operation was added ("ChangePermsAndRefreshWithFlushDataCache") +Previously, all calls to Operate with ChangePermsAndRefresh would flush data cache; now, calls to ChangePermsAndRefresh do not flush data cache and calls to ChangePermsAndRefreshWithFlushDataCache do. +ChangePermsAndRefreshWithFlushDataCache is otherwise identical to ChangePermsAndRefresh semantically. +QueryIoMapping now supports querying memory regions with KMemoryState_Static in addition to KMemoryState_Io. +Some changes surrounding KIoRegion: +KIoRegion now uses an intrusive red black tree member for the pool list, rather than an intrusive list node. +KIoPool::AddIoRegion() uses the intrusive tree to check fewer regions for Contains(). +KPageTableBase::UnmapIoRegion now takes the MemoryMapping as argument (which was passed to CreateIoRegion). +When mapping is MemoryMapping_Memory, the mapping following is done before unmap: +The region is permission changed to be uncached, using ChangePermsAndRefresh (without FlushDataCache). +The table's lock is released. +cpu::FlushDataCache() is called to flush the mapping. +The table's lock is reacquired. +All fallible operations now call KernelPanic() on failure, rather than returning the result code +KAddressSpaceInfo::GetAddressSpaceStart()/GetAddressSpaceSize() no longer use complicated switch logic to only examine the indices with the right bit-width, and instead just iterate all indices with an if to check bit width. +Big changes to KThread waiting/priority inheritance: +m_waiter_list, m_lock_owner fields were deleted. +New fields m_held_lock_info_list, m_waiting_lock_info were added. +This is an intrusive list of new type KThreadLockInfo (storing info on all locks held), and a pointer to the lock this thread is waiting on, if any. +There is one lock info for each address key. +KThreadLockInfo is slab allocated, count = # of KThreads +KThreadLockInfo has the following fields: +LockWithPriorityInheritanceThreadTree m_cv_tree; // Tree of threads waiting on the lock, this re-uses the node for condvar/arbiter. +KProcessAddress m_address_key; +KThread *m_owner; +u32 m_waiter_count; +This greatly simplifies RemoveWaiterByKey (as there is a single KThreadLockInfo representing all threads waiting on the key). +RemoveWaiterByKey now also has an output bool pointer for whether the lock still has waiters, rather than an output s32 pointer for # of waiters. +RestorePriority has been shuffled to ensure the new CV tree inside lock info has its invariants maintained across the priority set. +Several calls to RestorePriority are now guarded by if statements, to only invoke RestorePriority if there is a possible change in inherited priority. +Big changes to crt0/Initialize0/KInitialPageTable/Sleep Manager: +KInitialPageTable::Map (and others) now take a new physical-to-virtual-offset argument, and add this to L1 table etc. +Changes to Initial Arguments: +Initial arguments are now size 0x80. +Initial argument pointers are no longer used; Init arguments array addresses are used directly, with presumption that no page boundary is crossed. +Initial arguments no longer use setup function/etc. +Instead of setting ep = HorizonKernelMain, Initial arguments now set ep = InvokeMain (this function was previously "InvokeEntryPoint") +idle stack is now retrieved from KMemoryLayout inside InvokeMain, instead of being a field inside Initial Arguments. +After setting up initial arguments, Initialize0 now returns to crt0, which sets sp = InitArguments[0]->sp and calls new function ("Initialize1"). +All KInitialPageTable calls from here onward now pass g_LinearPhysToVirtDiff, and thus page table accesses are done using the Linear mapping set up by Initialize0. +Initialize1 does the following: +The initial identity mapping is unmapped in its entirety. +The single-page containing crt0 + interrupt vectors is re-identity-mapped as R-X. +PageAllocator for this is an extremely simplified new InitialPageAllocator type, which always has exactly two free pages to be allocated. +All remaining logic which used to be in Initialize0 happens here, with no changes. +TurnOnAllCores now calls a helper function ("TurnOnCore") to turn on the cores. +void TurnOnCore(__int64 core, InitArguments *argument); +TurnOnCore does virt->phys translation lookup (using at s1e1r) on StartOtherCore (from crt0 page) + argument, and calls smc::CpuOn directly. +TurnOnCore is "probably" a KSystemControl function. +Sleep handler thread function now sets resume entry addr = StartOtherCore, and sets up an InitArguments for each core. +ResumeEntry and ResumeEntryVirtual are now merged/simplified. +Changes to pool allocations: +Minimum non-secure system pool size is now ~2MB larger (0x2C04000 vs 0x2A0C000). +Slab heap gaps size is now 0x9000 smaller (0x1A7000 vs 0x1B0000). +KSystemControl::Initialize has been restructured (operations reordered), and now calls a helper which sets up the MT, creates system resource limit, etc. +This helper also modifies the KAddressSpaceInfo tables, when memory is large (these were previously read-only). +In particular, the following modifications are made to the 39-bit address space infos based on the total memory size: +size <= 8 GB: No changes (Heap Region = 8 GB, Alias region = 64 GB) +8 GB < size <= 16 GB: Heap Region = size, Alias Region = 8 * size +16 GB < size <= 32 GB: Heap region = size, Alias region = 128 GB +32 GB <= size: Heap region = 32 GB, Alias region = 128 GB +KSystemControl::Init::GenerateRandomRange now supports min=0, max=0xFFFFFFFFFFFFFFFF (previously it was incorrect for this case). +New InfoType (0x1B) ("IoRegionHint") +This takes a handle to a KIoRegion, and returns the low bits of the region's address. +If the region's size is < 0x10000, this is the low 12 bits, otherwise if size < 0x200000, this is the low 16 bits, otherwise it's the low 21 bits. +UserspaceAccess functions no longer do adr X30, fail in the loop, now do adr X#, fail before the loop and mov X30, X# in the loop. +All code which sets ThreadContext's pstate field now uses the mask 0xF0000000 for aarch64 threads and 0xFE0FFE20 for aarch32 threads. +Previously, this used the mask 0xFF0FFE20 for both. +This removes the ability to get/set the DIT bit for both aarch64 and aarch32, and removes many other bits for aarch64 only. +Interrupt disable logic was removed from a number of functions: +KAddressArbiter::SignalAndIncrementIfEqual, KAddressArbiter::SignalAndModifyBasedOnWaitingThreadCount, KAddressArbiter::WaitIfLessThan, KConditionVariable::SignalConditionVariableImpl +KConditionVariable::SignalToAddress now does dmb before copying updated value to userspace. +KDebugBase functions for DebugEvents were changed to take pointer to params + count, instead of 5 parameter arguments. +This propagates up to many/all caller functions. +The only variable length parameter counts are DebugEvent_Exception + DebugException_UserBreak/DebugException_DebuggerBreak +This copies the variable-count parameters directly to the result exception info without maximum size check. +This is not exploitable, because there is no way for userspace to control parameter count, and it will always remain in bounds. +Presumably exception info type is larger if compiling for a target with more than 4 CPUs, to prevent out-of-bounds copies. + +# [usb](https://switchbrew.org/wiki/USB_services) + +A vuln was [fixed](https://switchbrew.org/wiki/Switch_System_Flaws). + +# [bluetooth](https://switchbrew.org/wiki/Bluetooth_Driver_services) + +An IPC vuln due to a regression was [fixed](https://switchbrew.org/wiki/Switch_System_Flaws). + +# [LibraryAppletError](https://switchbrew.org/wiki/Error_Applet) + +As described [here](https://switchbrew.org/wiki/Title_list), nnSdk now supports two ErrorMessage SystemDataIds.
