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:
+Secure interrupt configuration are specified in an 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:
-#. 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,
- - 10-bit interrupt number,
+- 8-bit interrupt priority,
- - 8-bit interrupt priority,
+- Interrupt type (one of ``INTR_TYPE_EL3``, ``INTR_TYPE_S_EL1``,
+ ``INTR_TYPE_NS``),
- - 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.**
+- Interrupt configuration (either ``GIC_INTR_CFG_LEVEL`` or
+ ``GIC_INTR_CFG_EDGE``).
CPU specific operations framework
---------------------------------
compiling TF-A. Its value must be a numeric, and defaults to 0. See also,
*Armv8 Architecture Extensions* in `Firmware Design`_.
-- ``ARM_GIC_ARCH``: Choice of Arm GIC architecture version used by the Arm
- Legacy GIC driver for implementing the platform GIC API. This API is used
- by the interrupt management framework. Default is 2 (that is, version 2.0).
- This build option is deprecated.
-
- ``ARM_PLAT_MT``: This flag determines whether the Arm platform layer has to
cater for the multi-threading ``MT`` bit when accessing MPIDR. When this flag
is set, the functions which deal with MPIDR assume that the ``MT`` bit in
- ``FVP_GIC600`` : The GIC600 implementation of GICv3 is selected
- ``FVP_GICV2`` : The GICv2 only driver is selected
- ``FVP_GICV3`` : The GICv3 only driver is selected (default option)
- - ``FVP_GICV3_LEGACY``: The Legacy GICv3 driver is selected (deprecated)
- Note: If TF-A is compiled with this option on FVPs with GICv3 hardware,
- then it configures the hardware to run in GICv2 emulation mode
- ``FVP_USE_SP804_TIMER`` : Use the SP804 timer instead of the Generic Timer
for functions that wait for an arbitrary time length (udelay and mdelay).
