SceSysmem

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.

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. Same as write to RO but does a cache flush.

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.

} SceKernelPaddrListReq;

input.addr = vaddr;
input.length = length;
int sceKernelGetPaddrListForDriver(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.

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.

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.

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.
