Hello ! I'm wondering something about IOS_CreateThread :/

What's the proc and the arg because there's no "," between them :P

And the stack_top

Thanks if someone could give me more info about this "stack top" and the proc/arg

-It says under heading Syscalls (via syscall instruction) that "Currently only syscall 0x04 is still used in production versions of IOSU."

-This does not seem correct. I see several other Thumb SysCalls still in use on FW 5.5.x (15702)
-Example:
-    IOS_KERNEL:08133F44 Call_IOS_KERNEL__sys_close                                                ; CODE XREF: sub_8132C64+14
-    IOS_KERNEL:08133F44                               LDR             R12, =(__sys_close+1)
-    IOS_KERNEL:08133F48                               BX              R12 ; __sys_close
-    IOS_KERNEL:08133F4C off_8133F4C                   DCD __sys_close+1
-    IOS_KERNEL:08133F50 Call_IOS_KERNEL__sys_open

-    IOS_KERNEL:08133F54                               BX              R12 ; __sys_open

-    IOS_KERNEL:08133F5C Call_IOS_KERNEL__sys_read
-    IOS_KERNEL:08133F5C                               LDR             R12, =(__sys_read+1)

-IOS_KERNEL, IOS_NIM_BOSS, IOS_FPD,  use more than just 0x04, __sys_write0.

-:The disassembly you posted just looks like generated thunking stubs, are you sure they're referenced by other code? [[User:Tueidj|Tueidj]] ([[User talk:Tueidj|talk]]) 11:31, 30 April 2016 (CEST)
-Technically, the statement "Used by Production units" excludes the use of Debug mode, and the functions above are still in-use for what is shipping in Production Unit's Debug code (all of the above are used if the user press "1" in debug mode), so I'm suggesting they be tagged as "Debug Units Only" instead of "unused".
