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 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.

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.
