NSKBL is a program that performs emmc setup, base kernel module loading, etc. during PSVita boot.
Module
The non-secure kernel bootloader contains an embedded and likely stripped version of SceSysmem, SceKernelModulemgr, SceSblSmschedProxy, SceExcpmgr, SceKernelIntrMgr, SceSblAuthMgr, SceProcessmgr (maybe), SceSdif, SceIofilemgr (Simple version?), and some other core drivers.
How to debug NSKBL
NSKBL supports sd0: for debugging.
sysroot->boot_type_indicator_1:0x40000 is required.
Types
/* Many pointers are NSKBL heap relationships */ typedef struct SceNskblSysrootInfo { // size is at least 0xC8 on FW 3.60 SceUID unk_0x00; // maybe some PID. ex: 0x10089 int unk_0x04; void *unk_0x08; void *unk_0x0C; void *unk_0x10; void *unk_0x14; void *unk_0x18; void *unk_0x1C; void *unk_0x20; void *unk_0x24; void *unk_0x28; void *unk_0x2C; SceUID unk_0x30; // maybe some PID. ex: 0x1000B const void *unk_0x34; // mapped paddr in vaddr const void *unk_0x38; // mapped paddr in vaddr void *unk_0x3C; int unk_0x40; // ex: 0x80000000 int unk_0x44; // ex: 0x20000000 void *unk_0x48; void *unk_0x4C; void *unk_0x50; void *unk_0x54; void *unk_0x58; void *unk_0x5C; void *unk_0x60; void *unk_0x64; void *unk_0x68; void *unk_0x6C; void *unk_0x70; void *unk_0x74; void *unk_0x78; void *unk_0x7C; void *unk_0x80; void *unk_0x84; void *unk_0x88; void *unk_0x8C; void *unk_0x90; void *unk_0x94; void *unk_0x98; SceUInt32 magic; // 0x 19442EA8 int unk_0xA0; // ex: 0x1000 int unk_0xA4; // ex: 0x1000 int unk_0xA8; // ex: 0x40000 int unk_0xAC; // ex: 0x200000 int unk_0xB0; // ex: 7 int unk_0xB4; int unk_0xB8; // ex: 0x80 sysroot360_t *pSysroot; void *unk_0xC0; void *unk_0xC4; // more...? } SceNskblSysrootInfo; // 3.60 SceNskblSysrootInfo *nskbl_sysroot_info = (SceNskblSysrootInfo *)(0x51000000 + 0x138980); // 3.60
