Function Documentation

void bad_mode

(

void

)

FIXME.

Referenced by do_data_abort(), do_fiq(), do_irq(), do_not_used(), do_prefetch_abort(), do_software_interrupt(), and do_undefined_instruction().

void do_data_abort

(

struct pt_regs *

pt_regs

)

The CPU catches a data abort.

That really should not happen!

Parameters:

[in]

pt_regs

Register set content when the accident happens

FIXME: What does it mean, why is reset the only solution?

void do_fiq

(

struct pt_regs *

pt_regs

)

The CPU catches a fast interrupt request.

Parameters:

[in]

pt_regs

Register set content when the interrupt happens

FIXME: What does it mean, why is reset the only solution?

void do_irq

(

struct pt_regs *

pt_regs

)

The CPU catches a regular interrupt.

Parameters:

[in]

pt_regs

Register set content when the interrupt happens

FIXME: What does it mean, why is reset the only solution?

void do_not_used

(

struct pt_regs *

pt_regs

)

The CPU catches a not-used(?) abort.

Parameters:

[in]

pt_regs

Register set content when the accident happens

FIXME: What does it mean, why is reset the only solution?

void do_prefetch_abort

(

struct pt_regs *

pt_regs

)

The CPU catches a prefetch abort.

That really should not happen!

Parameters:

[in]

pt_regs

Register set content when the accident happens

FIXME: What does it mean, why is reset the only solution?

void do_software_interrupt

(

struct pt_regs *

pt_regs

)

The CPU catches a software interrupt.

Parameters:

[in]

pt_regs

Register set content when the interrupt happens

There is not functione behind this feature. So what to do else than a reset?

void do_undefined_instruction

(

struct pt_regs *

pt_regs

)

The CPU runs into an undefined instruction.

That really should not happen!

Parameters:

[in]

pt_regs

Register set content when the accident happens

void show_regs

(

struct pt_regs *

regs

)

Display current register set content.

Parameters:

[in]

regs
