Configuring secure interrupts
|
||||
-----------------------------
|
||||
|
||||
The GIC driver is responsible for performing initial configuration of secure
|
||||
interrupts on the platform. To this end, the platform is expected to provide the
|
||||
GIC driver (either GICv2 or GICv3, as selected by the platform) with the
|
||||
interrupt configuration during the driver initialisation.
|
||||
|
||||
There are two ways to specify secure interrupt configuration:
|
||||
|
||||
#. Array of secure interrupt properties: In this scheme, in both GICv2 and GICv3
|
||||
driver data structures, the ``interrupt_props`` member points to an array of
|
||||
interrupt properties. Each element of the array specifies the interrupt
|
||||
number and its configuration, viz. priority, group, configuration. Each
|
||||
element of the array shall be populated by the macro ``INTR_PROP_DESC()``.
|
||||
The macro takes the following arguments:
|
||||
|
||||
- 10-bit interrupt number,
|
||||
|
||||
- 8-bit interrupt priority,
|
||||
|
||||
- Interrupt type (one of ``INTR_TYPE_EL3``, ``INTR_TYPE_S_EL1``,
|
||||
``INTR_TYPE_NS``),
|
||||
|
||||
- Interrupt configuration (either ``GIC_INTR_CFG_LEVEL`` or
|
||||
``GIC_INTR_CFG_EDGE``).
|
||||
|
||||
#. Array of secure interrupts: In this scheme, the GIC driver is provided an
|
||||
array of secure interrupt numbers. The GIC driver, at the time of
|
||||
initialisation, iterates through the array and assigns each interrupt
|
||||
the appropriate group.
|
||||
|
||||
- For the GICv2 driver, in ``gicv2_driver_data`` structure, the
|
||||
``g0_interrupt_array`` member of the should point to the array of
|
||||
interrupts to be assigned to *Group 0*, and the ``g0_interrupt_num``
|
||||
member of the should be set to the number of interrupts in the array.
|
||||
|
||||
- For the GICv3 driver, in ``gicv3_driver_data`` structure:
|
||||
|
||||
- The ``g0_interrupt_array`` member of the should point to the array of
|
||||
interrupts to be assigned to *Group 0*, and the ``g0_interrupt_num``
|
||||
member of the should be set to the number of interrupts in the array.
|
||||
|
||||
- The ``g1s_interrupt_array`` member of the should point to the array of
|
||||
interrupts to be assigned to *Group 1 Secure*, and the
|
||||
``g1s_interrupt_num`` member of the should be set to the number of
|
||||
interrupts in the array.
|
||||
|
||||
**Note that this scheme is deprecated.**

This document lists the optional platform interrupt controller API that
|
||||
abstracts the runtime configuration and control of interrupt controller from the
|
||||
generic code. The mandatory APIs are described in the `porting guide`__.
|
||||
|
||||
.. __: porting-guide.rst#interrupt-management-framework-in-bl31

|
||||
Function: unsigned int plat_ic_get_running_priority(void); [optional]
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
::
|
||||
|
||||
Argument : void
|
||||
Return : unsigned int
|
||||
|
||||
This API should return the priority of the interrupt the PE is currently
|
||||
servicing. This must be be called only after an interrupt has already been
|
||||
acknowledged via. ``plat_ic_acknowledge_interrupt``.
|
||||
|
||||
In the case of ARM standard platforms using GIC, the *Running Priority Register*
|
||||
is read to determine the priority of the interrupt.
|
||||
|
||||
Function: int plat_ic_is_spi(unsigned int id); [optional]
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
::
|
||||
|
||||
Argument : unsigned int
|
||||
Return : int
|
||||
|
||||
The API should return whether the interrupt ID (first parameter) is categorized
|
||||
as a Shared Peripheral Interrupt. Shared Peripheral Interrupts are typically
|
||||
associated to system-wide peripherals, and these interrupts can target any PE in
|
||||
the system.
|
||||
|
||||
Function: int plat_ic_is_ppi(unsigned int id); [optional]
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
::
|
||||
|
||||
Argument : unsigned int
|
||||
Return : int
|
||||
|
||||
The API should return whether the interrupt ID (first parameter) is categorized
|
||||
as a Private Peripheral Interrupt. Private Peripheral Interrupts are typically
|
||||
associated with peripherals that are private to each PE. Interrupts from private
|
||||
peripherals target to that PE only.
|
||||
|
||||
Function: int plat_ic_is_sgi(unsigned int id); [optional]
|

Argument : unsigned int
|
||||
Return : int
|
||||
|
||||
The API should return whether the interrupt ID (first parameter) is categorized
|
||||
as a Software Generated Interrupt. Software Generated Interrupts are raised by
|
||||
explicit programming by software, and are typically used in inter-PE
|
||||
communication. Secure SGIs are reserved for use by Secure world software.
|
||||
|
||||
Function: unsigned int plat_ic_get_interrupt_active(unsigned int id); [optional]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|

::
|

Argument : unsigned int
|

Return : int
|
||||
|
||||
This API should return the *active* status of the interrupt ID specified by the
|
||||
first parameter, ``id``.
|
||||
|
||||
In case of ARM standard platforms using GIC, the implementation of the API reads
|
||||
the GIC *Set Active Register* to read and return the active status of the
|
||||
interrupt.
|
||||
|
||||
Function: void plat_ic_enable_interrupt(unsigned int id); [optional]
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
::
|
||||
|
||||
Argument : unsigned int
|
||||
Return : void
|
||||
|
||||
This API should enable the interrupt ID specified by the first parameter,
|
||||
``id``. PEs in the system are expected to receive only enabled interrupts.
|
||||
|
||||
In case of ARM standard platforms using GIC, the implementation of the API
|
||||
inserts barrier to make memory updates visible before enabling interrupt, and
|
||||
then writes to GIC *Set Enable Register* to enable the interrupt.
|
||||
|
||||
Function: void plat_ic_disable_interrupt(unsigned int id); [optional]
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
::
|
||||
|
||||
Argument : unsigned int
|
||||
Return : void
|
||||
|
||||
This API should disable the interrupt ID specified by the first parameter,
|
||||
``id``. PEs in the system are not expected to receive disabled interrupts.
|
||||
|
||||
In case of ARM standard platforms using GIC, the implementation of the API
|
||||
writes to GIC *Clear Enable Register* to disable the interrupt, and inserts
|
||||
barrier to make memory updates visible afterwards.
|
||||
|
||||
Function: void plat_ic_set_interrupt_priority(unsigned int id, unsigned int priority); [optional]
|

::
|
||||
|

Argument : unsigned int
|

Argument : unsigned int
|
||||
Return : void
|
||||
|
||||
This API should set the priority of the interrupt specified by first parameter
|
||||
``id`` to the value set by the second parameter ``priority``.
|
||||
|
||||
In case of ARM standard platforms using GIC, the implementation of the API
|
||||
writes to GIC *Priority Register* set interrupt priority.
|
||||
|
||||
Function: int plat_ic_has_interrupt_type(unsigned int type); [optional]
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
::
|
||||
|
||||
Argument : unsigned int
|
||||
Return : int
|
||||
|
||||
This API should return whether the platform supports a given interrupt type. The
|
||||
parameter ``type`` shall be one of ``INTR_TYPE_EL3``, ``INTR_TYPE_S_EL1``, or
|
||||
``INTR_TYPE_NS``.
|
||||
|
||||
In case of ARM standard platforms using GICv3, the implementation of the API
|
||||
returns ``1`` for all interrupt types.
|
||||
|
||||
In case of ARM standard platforms using GICv2, the API always return ``1`` for
|
||||
``INTR_TYPE_NS``. Return value for other types depends on the value of build
|
||||
option ``GICV2_G0_FOR_EL3``:
|
||||
|
||||
- For interrupt type ``INTR_TYPE_EL3``:
|
||||
|
||||
- When ``GICV2_G0_FOR_EL3`` is ``0``, it returns ``0``, indicating no support
|
||||
for EL3 interrupts.
|
||||
|
||||
- When ``GICV2_G0_FOR_EL3`` is ``1``, it returns ``1``, indicating support for
|
||||
EL3 interrupts.
|
||||
|
||||
- For interrupt type ``INTR_TYPE_S_EL1``:
|
||||
|
||||
- When ``GICV2_G0_FOR_EL3`` is ``0``, it returns ``1``, indicating support for
|
||||
Secure EL1 interrupts.
|
||||
|
||||
- When ``GICV2_G0_FOR_EL3`` is ``1``, it returns ``0``, indicating no support
|
||||
for Secure EL1 interrupts.

Argument : unsigned int
|

Return : void
|
||||
|
||||
This API should set the interrupt specified by first parameter ``id`` to the
|
||||
type specified by second parameter ``type``. The ``type`` parameter can be
|
||||
one of:
|
||||
|
||||
- ``INTR_TYPE_NS``: interrupt is meant to be consumed by the Non-secure world.
|
||||
|
||||
- ``INTR_TYPE_S_EL1``: interrupt is meant to be consumed by Secure EL1.
|
||||
|
||||
- ``INTR_TYPE_EL3``: interrupt is meant to be consumed by EL3.
|
||||
|
||||
In case of ARM standard platforms using GIC, the implementation of the API
|
||||
writes to the GIC *Group Register* and *Group Modifier Register* (only GICv3) to
|
||||
assign the interrupt to the right group.
|
||||
|
||||
For GICv3:
|
||||
|
||||
- ``INTR_TYPE_NS`` maps to Group 1 interrupt.
|
||||
|
||||
- ``INTR_TYPE_S_EL1`` maps to Secure Group 1 interrupt.
|
||||
|
||||
- ``INTR_TYPE_EL3`` maps to Secure Group 0 interrupt.
|
||||
|
||||
For GICv2:
|
||||
|
||||
- ``INTR_TYPE_NS`` maps to Group 1 interrupt.
|
||||
|
||||
- When the build option ``GICV2_G0_FOR_EL3`` is set to ``0`` (the default),
|
||||
``INTR_TYPE_S_EL1`` maps to Group 0. Otherwise, ``INTR_TYPE_EL3`` maps to
|
||||
Group 0 interrupt.

Return : void
|

This API should raise an EL3 SGI. The first parameter, ``sgi_num``, specifies
|
||||
the ID of the SGI. The second parameter, ``target``, must be the MPIDR of the
|
||||
target PE.
|
||||
|
||||
In case of ARM standard platforms using GIC, the implementation of the API
|
||||
inserts barrier to make memory updates visible before raising SGI, then writes
|
||||
to appropriate *SGI Register* in order to raise the EL3 SGI.
|
||||
|

This API should set the routing mode of Share Peripheral Interrupt (SPI)
|
||||
specified by first parameter ``id`` to that specified by the second parameter
|
||||
``routing_mode``.
|
||||
|
||||
The ``routing_mode`` parameter can be one of:
|
||||
|
||||
- ``INTR_ROUTING_MODE_ANY`` means the interrupt can be routed to any PE in the
|
||||
system. The ``mpidr`` parameter is ignored in this case.
|
||||
|
||||
- ``INTR_ROUTING_MODE_PE`` means the interrupt is routed to the PE whose MPIDR
|
||||
value is specified by the parameter ``mpidr``.
|
||||
|
||||
In case of ARM standard platforms using GIC, the implementation of the API
|
||||
writes to the GIC *Target Register* (GICv2) or *Route Register* (GICv3) to set
|
||||
the routing.
