SceSysmem

SceSysmem is a kernel module that acts as the heart of the kernel. It exports multiple libraries for various features. SceSysmem is the first module that is loaded in the kernel load sequence and its libraries are imported by almost all other modules. See Virtual Memory and Physical Memory for more details on the memory subsystem.

Module
This module exists in both non-secure and secure world. The non-secure world SELF can be found in. It also can be found in the Boot Image.

Known NIDs
The SceCpu libraries provide wrappers for much ARM CP15 co-processor access as well as low level support of spinlocks and other synchronization primitives.

Memory Block Type
The  parameter indicates what kind of memory to allocate. Here is a mapping of  flags to ARM MMU flags. Higher bits are used for other options including where to allocate from. Not all flag values are valid, there is a table of valid types in the kernel. You cannot, for example, allocate RWX memory.

All memtype list for 3.60

Note

The only commonly available memtypes are those that are publicly available.

sceKernelAllocMemblockInternal uses a list to translate it into an internal memtype.

So we can't create memtype with any bits and use that's.

memtype bit value
This is based internal memtypes.

Spinlock functions

The following functions implement a simple mutal exclusion mechanism using atomic operation (LDREX/STREX). Spinlocks are owned by a single thread or CPU at a time. Unlike other lock/sync objects of the kernel, spinlocks can be used under any context. Use spinlocks if the data to protect may be accessed from an IRQ or exception handler.

There are two version of the Spinlock functions: normal functions do not change the CPU state, while the  functions ensure the CPU cannot be interrupted while the lock is held.

The same type of function must be used to lock and unlock a spinlock: for example, calling  followed by   is an invalid usage of this API.

Spinlocks can take two values:  means the spinlock is unlocked, and   means the spinlock is locked.

sceKernelSpinlockLowLockForDriver

Temp name was sceKernelCpuUnlockResumeIntrStoreLRForDriver, sceKernelCpuResumeIntrForDriver.

If interrupts were disabled before acquiring the spinlock, they will remain disabled after this call.

RW Spinlock functions

The following functions implement RW spinlocks. This variant of the spinlock allows multiple threads/CPUs to access data at the same time as long as only reads are performed. When acquired for writing, a single thread at a time can access the data and is thus free to modify it. Like regular spinlocks, the RW spinlocks can be used under any context. Use RW spinlocks if the data to protect may be accessed from an IRQ or exception handler.

Like for regular spinlocks, all RWSpinlock functions are available in a normal and  version. Additionally, every function exists in  and   variants, depending on whether the caller wants to read or write to the object protected by the lock.

Like for regular spinlocks, the same type of function must be used to lock and unlock a RW spinlock. Calling  followed by   is an invalid usage of this API. Calling  followed by    is also an invalid usage of this API.

RW Spinlocks can take three kind of values:  means the spinlock is unlocked,   means the spinlock is write-locked, and a positive value   means that   readers have read-locked the spinlock.

sceKernelRWSpinlockLowReadLockForDriver
This is a guessed name. Temp name was sceKernelCpuSpinLockStoreLRForDriver.
