SceSysmem is a kernel module that acts as the heart of the kernel. It exports multiple libraries for different functionalities (one of the few modules that do so). SceSysmem is the first module that is loaded in the kernel load sequence and its libraries are imported by almost all other modules. See 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 os0:kd/sysmem.skprx
. It also can be found in the Boot Image.

Memory Block Type
The type
parameter indicates what kind of memory to allocate. Here is a mapping of type
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.

The interface is the same as the user version of this call, however more types can be specified and more options are in the pOpt argument.
To allocate a kernel RW block of memory, specify type = 0x6020D006
.
To allocate a block of memory with a specific physical address, specify type = 0x20100206
, pOpt->attr = 2
, and pOpt->paddr = physical address
.
To allocate a block of memory that is kernel executable, specify type = 0x1020D005
.
To allocate a block of memory that is physically contiguous, specify type = 0x30808006
, pOpt->attr = 0x200004
and an alignment to pOpt->alignment
.
To allocate a block of memory inside the CDRAM, specify type = 0x40404006
.
Unrestricted Write for Process
Unrestricted memcpy to the virtual address space for process pid
. Both dst
and src
must be in the address space of pid
but src
must also be accessible in the address space of the caller. This is normally used for resolving stubs in module loads.

an array of addr_pair

will contain the number of entries written. If output_buffer
is null, it will just write the count.

Permission is either "1" for read only, no execute or "2"/"3" for read write, no execute. Type is either 0, 1, or 17 and affects the block type. 0 is default. This will allocate kernel memory starting at kernel_page. To get the same memory as the user pointer, add the kernel_offset. kernel_size is how much is allocated.
//this signature is for 1.69
int map_user_to_kernel(int permission, int type, void *user_buf, int size, void **kernel_page, int *kernel_size, int *kernel_offset);

SceSysmem
The SceSysmem library is responsible for both low-level and high-level memory management. There are functions for allocating raw blocks of memory (similar to Linux sbrk
) as well as functions for maintaining a heap-like structure (similar to malloc
) for kernel, however SceLibKernel implements a proper heap and that is used for user code.

void SceCpuForDriver_7BB9D5DF_unlock_int(int *addr, int prev_state);
Same as the pair above, but while mutex is held, interrupts are disabled. Used like this:
int prev_state = SceCpuForDriver_D32ACE9E_lock_int(mutex);
// do work
SceCpuForDriver_7BB9D5DF_unlock_int(mutex, prev_state);

Libraries can register callbacks for handling suspend/resume related events.

typedef struct {
uint32_t size; // 24
uint32_t unk1;

typedef int (suspend_callback_t)(int resume, int eventid, suspend_args_t *args, void *opt);
int suspend_register_callback(const char *name, suspend_callback_t *callback_func, void *opt);
Registers a function for handling suspend/resume. resume
is 0 if we are currently suspending and 1 if we are currently resuming. opt
is passed from the registration. Registration
adds an entry to a linked list and returns the block id for the new entry.
Unregister
Version |
NID
|
1.69 |
0xDD61D621
|
int suspend_unregister(int id);
Call with the id returned from suspend_register_callback
to remove the entry from the linked list and free the memory.
Make Callback
Version |
NID
|
1.69 |
0xD4622EA8
|
int suspend_make_callback(int resume, int eventid, suspend_args_t *args, int stop_on_error);
This will go through the linked list and call each callback. If stop_on_error
is set, then the first callback that returns a negative value will stop the call chain and return the block id of the callback that broke the chain. Otherwise, this function will invoke each callback and return zero.
