28 | * This file defines - for the TSAR_MIPS32 architecture - types that can be used |
---|
29 | * by both the kernel and the user applications. |
---|
30 | * |
---|
31 | * - the <reg_t> type, is used by the hal_user_syscall() function, called by |
---|
32 | * several user-level libraries to pass syscall arguments to the kernel, |
---|
33 | * and used by the do_syscall() kernel function, to analyse arguments. |
---|
34 | * It is also used by the hal_*_irq() kernel functions to save/restore |
---|
35 | * the SR register value. |
