 Posted: Tue Sep 19, 2006 7:58 am Post subject: Some new nids (sceNand, ModuleMgrForKernel, ...) |
 |
|
Today i felt like wanting to hunt nids :P
sceNand (all firmwares):
C478C1DE - sceNandReadPagesRawAll
E05AE88D - sceNandReadPagesRawExtra
BADD5d46 - sceNandWritePagesRawAll
8932166A - sceNandWritePagesRawExtra
ModuleMgrForKernel(2.00+):
0x3E4FEDDC - sceKernelLoadModuleToBlock
0x61EC6AB0 - sceKernelModuleMgrMode
0xF80F3C96 - sceKernelLoadModuleBufferBootInitConfig
LoadCoreForKernel(2.00+):
0x3BB7AC18 - sceKernelLoadCoreMode
IoFileMgrForKernel(2.80+):
0x5216CE3F - sceIoTerminateFd (this one requires confirmation)
sceIoFilemgrDNAS_driver (2.7X only, since in 2.80 the module has changed and doesn't export anything):
0x0144AFDA - sceIoLseekDNAS
0x4B4AAA29 - sceIoEndDNAS
0x79A425A4 - sceIoInitDNAS
0x8E56CAA1 - sceIoReadDNAS
0x9F645A9C - sceIoCloseDNAS
These ones seem to be used to open files protected with some kind of drm. sceIoFilemgrDNAS_driver_AA46A25E would be like "sceIoOpenDNAS", although that's not the name. |

Niice :)
About nids, tell me , do you know why in the sc_sascore.prx which is in flash0 there are none of the functions which are in the sc_sascore.prx which is in the umds. Hereafter is the list of function names of the umd sascore:
| Code: |
sceSasCore
sceSasExit
sceSasGetEndFlag
sceSasGetEnvelopeHeight
sceSasInit
sceSasRevEVOL
sceSasRevParam
sceSasRevType
sceSasRevVON
sceSasSetADSR
sceSasSetADSRmode
sceSasSetEffect
sceSasSetEffectType
sceSasSetEffectVolume
sceSasSetKeyOff
sceSasSetKeyOn
sceSasSetNoise
sceSasSetPitch
sceSasSetSimpleADSR
sceSasSetSL
sceSasSetVoice
sceSasSetVolume

in 2.8 libasfparser.prx
0x2CB147F7 sceAsfGetFrameData
0x8B08301F sceAsfParserEndEntry
0xB9E4BD9E sceAsfParserStartEntry
in 2.8 usbmic
0x63400E20 sceUsbMicGetInputLength
(p.s. only one functions is left unknow.)
I have a question. There are many strings inside the string-dump of the prx, some of them look likes a function name but it is not (it not pass the NIDs search). Are they the internal function name? |

Yes, they're internal functions. You could trace them and give thir addresses though :)
It may also be possible that those functions are inline, like the sceSas, or some sceMSCM functions. |

Thanks for information
Also some functions look have problem under ps2dis , for examples:
| Code: |
sceUsbBus_driver_90B82F55:
li v0 , $00000001
lui a0 $0000
jr ra
sw v0 $00000604
|
My understanding is , after jr ra is called, the function should jump back to the orginial function, and the last command should not run, right? Does it mean the last command is not belong to sceUsbBus_driver_90B82F55 but the next function sceUsbBus_driver_7B87815D? or the prxtool generate the wrong address inside the map file?

- a normal ''branch'' instruction does something like:
| Code: | if(condition){
delay_instruction();
goto whatever_address;
} else {
delay_instruction();
} |
examples: J, JR, BEQ, BNE, BGEZ,...
- however, the ''branch likely'' instructions are of this form:
| Code: | if(condition){
delay_instruction();
goto whatever_address;
} |
examples: BEQL, BNEL, ... |
