SceSysmem: Difference between revisions

Revision as of 12:43, 9 July 2023

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.

Note

The only commonly available memtypes are those that are publicly available.

sceKernelAllocMemblockInternal uses a list to translate it into an internal memtype.

So we can't create memtype with any bits and use that's.

Version	NID
0.931.010-1.692.000	0xA7D44B50
1.800.071-3.740.011	not present

A guessed name is sceKernelSetSysmemFuncForKernel.

Used by SceKernelSSProxy's module_start to register a function that just calls SMC 0x10E (BusErrorClear).

The registered function is used internally by #sceKernelPhysicalMemReadForKernel and #sceKernelPhysicalMemWriteForKernel.

int SceSysmemForKernel_A7D44B50(void* pBusErrorClearFunc);

sceKernelSysmemModuleStartAfterProcessmgrForKernel

Version	NID
3.60-3.61	0xE7938BFB

Version	NID
0.931.010-1.060.031	0x4B86A751
1.50-3.740.011	not present

Writes to physical address pdest using a pre-allocated memblock. Destination must belong into a hardcoded table describing physical ranges.

SceSSize sceKernelPhysicalMemWriteForKernel(SceUIntPAddr pdest, const void *src, SceSize size);

sceKernelPhysicalMemReadForKernel

Version	NID
0.931.010-1.060.031	0xF96E3AE2
1.50-3.740.011	not present

Temp name was memcpy_from_paddr.

Dest must be a virtual address and src must be a physical address. Returns copied size on success.

int sceKernelPhysicalMemReadForKernel(void *dest, const void *src, SceSize dest_size, SceSize src_size);

sceKernelCopyFromUser32DomainForKernel

Version	NID
0.931	0xD530399A

sceKernelCopyToUserProcTextDomainForKernel

Version	NID
0.931-3.60	0x30931572
3.65	0x2995558D

Temp name was sceKernelRxMemcpyKernelToUserForPidForKernel, sceKernelProcCopyToUserRxForKernel.

Same as sceKernelCopyToUserProcDomain, but performs a DCache clean after the copy. Use this function if you want to write code in user pages.

This function is usually called when resolving stubs during a module loads. In 3.60, DACR is set to 0x15450FC3 instead of 0xFFFFFFFF.

SceInt32 sceKernelCopyToUserProcTextDomainForKernel(SceUID pid, void *uaddr, const void *kaddr, SceSize size);

sceKernelCopyToUserTextDomainForKernel

Version	NID
3.60	0x67BAD5B4
3.65	0x5EF1DAAF

This is a guessed name. Temp names were sceKernelMemcpyToUserRxForKernel, sceKernelCopyToUserRxForKernel.

Similar to sceKernelCopyToUserProcTextDomain, but performed in the current address space.

In FW 3.60, sceKernelCopyToUserProcTextDomain calls this function to perform the copy after changing address space.

SceInt32 sceKernelCopyToUserTextDomainForKernel(void *dst, const void *src, SceSize len);

sceKernelCopyToUserDomainForKernel

Version	NID
0.931	Not present
3.60-3.61	0xA6F95838
3.63	0x499A9FFF

This is a guessed name. Temp names were sceKernelMemcpyToUserRoForKernel, sceKernelCopyToUserRoForKernel.

Similar to sceKernelCopyToUserTextDomain, but doesn't perform any DCache clean.

Uses the same DACR, 0x15450FC3, for the copy.

int sceKernelCopyToUserDomainForKernel(void *dst, const void *src, SceSize len);
