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.

Mask Value Description
0x10000 0x10000 Global. nG bit NOT set
0xFF00 0x800 B bit set. Sharable device memory.
0xFF00 0x2000 TEX[2] and TEX[0] bit set. Outer cache Write-back, Write-Allocate. Inner cache non-cachable.
0xFF00 0x4000 TEX[2] and B bit set. Outer cache non-cachable. Inner cache Write-back, Write-Allocate
0xFF00 0x8000 TEX[0] bit set. S bit unset. Outer and inner non-cachable. Not sharable.
0xFF00 0xD000 TEX[0] bit set. C,B bits set. Outer and inner Write-back, Write-Allocate.
0xFF 0x4 AP[2:0] = 5, XN=1. Privileged RO, User NA.
0xFF 0x5 AP[2:0] = 5. Privileged RX, User NA.
0xFF 0x6 AP[2:0] = 1, XN=1. Privileged RW, User NA.
0xFF 0x7 AP[2:0] = 1. Privileged RWX, User NA. (Never used)
0xFF 0x50 AP[2:0] = 7. Privileged RX, User RX.
0xFF 0x60 AP[2:0] = 3, XN=1. Privileged RW, User RW.
0xFF 0x40 AP[2:0] = 7, XN=1. Privileged RO, User RO.

int sceKernelAllocMemBlockForKernel(const char *name, int32_t type, uint32_t vsize, struct SceKernelAllocMemKernelBlockOpt *pOpt);

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 or type = 0x20100806, 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.

Version World NID
1.69 non-secure 0x30931572 
int unrestricted_memcpy_for_pid(int pid, void *dst, void *src, size_t len);

sceKernelFindClassByNameForKernel

1.69 non-secure 0x6D88EF8A 
int sceKernelMemcpyKernelToUser(uint32_t uaddr, const void *kaddr, uint32_t len);

sceKernelMemcpyUserToKernel

Version World NID
1.69 non-secure 0xBC996A7A 
int sceKernelMemcpyUserToKernel(void *kaddr, uint32_t uaddr, uint32_t len);

sceKernelMemcpyUserToKernelForPid

Version World NID
3.60 non-secure 0x605275F8 
int sceKernelMemcpyUserToKernelForPid(int pid, void *kaddr, uint32_t uaddr, uint32_t len);

Same as above, but copies from the specified process.

strncpyKernelToUser

1.69 non-secure 0x80BD6FEB 
int strncpyKernelToUser(uint32_t uaddr, const void *kaddr, uint32_t maxlen);

strncpyUserToKernel

Version World NID
1.69 non-secure 0xDB3EC244 
int strncpyUserToKernel(void *kaddr, uint32_t uaddr, uint32_t maxlen);

strnlenUserSrc

Version World NID
1.69 non-secure 0xB429D419 
int strnlenUserSrc(uint32_t uaddr, uint32_t maxlen);

get_paddr

Version World NID
1.69 non-secure 0x8D160E65
3.60 ? 0x8D160E65
1.69 secure 0x1DEADF6C 
int get_paddr(void *vaddr, void **result);

This will write the physical address for a virtual address vaddr to memory pointed to by result. Returns <0 on error, values >=0 indicate success.

sceKernelGetPaddrList

Version World NID
1.69 non-secure 0xE68BEEBD 
typedef struct SceKernelAddrPair {
	uint32_t addr;
	uint32_t length;
} SceKernelAddrPair;

typedef struct SceKernelPaddrListReq {
	uint32_t size; // 0x14
	uint32_t output_buffer_size;
	uint32_t unk;
	uint32_t ret_count;
	SceKernelAddrPair *output_buffer;
} SceKernelPaddrListReq;

input.addr = vaddr;
input.length = length;
int sceKernelGetPaddrList(SceKernelAddrPair *input, SceKernelPaddrListReq *req);

This function takes in two parameters: an array of length 2 specifying the virtual address and the size of the block of memory and a request information. The function will write into output_buffer an array of addr_pair that encompasses the block of memory specified in the input. req->ret_count will contain the number of entries written. If output_buffer is null, it will just write the count.

sceKernelGetMemBlockBaseForDriver

Version World NID

Version World NID
1.05 non-secure 0x8d332ae1
1.69 non-secure 0xDFE2C8CB 
int sysmem_remap(int blkid, int type);

This is used to remap RW memory as RX. To do this, first allocate a memory block of type 0x1020D006. After you are done writing, call this with type set to 0x1020D005.

Create Heap Pool

Version World NID
1.69 non-secure 0x9328E0E8 
typedef struct {
    int size; // 28
    int flags; // usually 0x1 
    int unk;
    int unk;
    int block_type;
    int unk;
    int unk;
} pool_arg_t;
int heap_pool_create(const char *name, int size, pool_arg_t *opt); // opt can be NULL

The heap pool is thread safe.

Map User to Kernel

Version World NID
1.69 non-secure 0x7D4F8B5F
3.60 ? 0x7D4F8B5F

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);

//this signature is for 3.60 - now allows to give a name
int map_user_to_kernel(char *name, int permission, int type, void *user_buf, int size, void **kernel_page, int *kernel_size, int *kernel_offset);

Map User to Kernel Default

Version World NID
3.60 ? 0x278BC201

assigns type 0

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.

SceKernelSuspendForDriver

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

Register Callback

Version NID
1.69 0x04C05D10 
typedef struct {
    uint32_t size; // 24
    uint32_t unk1;
    uint32_t unk2;
    uint32_t unk3;
    uint32_t unk4;
    uint32_t unk5;
} suspend_args_t;
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.
