SceSysmem: Difference between revisions

Revision as of 22:25, 5 May 2018

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.

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.

int sceKernelGetPaddrForDriver(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.

sceKernelGetPaddrListForDriver

Version	World	NID
1.69	non-secure	0xE68BEEBD

} 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.

int sceKernelAllocMemBlockForDriver(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.

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

Used to register callbacks for handling suspend/resume related events.

sceKernelRegisterSysEventHandlerForDriver

Version	NID
1.69	0x04C05D10
3.60	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 event_id, suspend_args_t *args, void *opt);

int sceKernelSuspendRegisterCallbackForDriver(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.

Returns the suspend_callback_id.

sceKernelUnregisterSysEventHandlerForDriver

Version	NID
1.69	0xDD61D621
3.60	0xDD61D621

int sceKernelUnregisterSysEventHandlerForDriver(int id);

Call with the id returned from suspend_register_callback to remove the entry from the linked list and free the memory.

sceKernelSysEventDispatchForDriver

Version	NID
1.69	0xD4622EA8
3.60	0xD4622EA8

int sceKernelSysEventDispatchForDriver(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.

sceKernelPowerTickForDriver

Version	NID
3.60	0xE0489831

typedef enum SceKernelPowerTickType {
	/** Cancel all timers */
	SCE_KERNEL_POWER_TICK_DEFAULT			= 0,

	/** Cancel OLED dimming timer */
	SCE_KERNEL_POWER_TICK_DISABLE_OLED_DIMMING	= 6
} SceKernelPowerTickType;

int sceKernelPowerTickForDriver(int type);

Cancel specified idle timers to prevent entering in power save processing.

Returns 0 on success.
