Platform initialization
~~~~~~~~~~~~~~~~~~~~~~~
-In this configuration, when the CPU resets to BL31 there should be no parameters
-that can be passed in registers by previous boot stages. Instead, the platform
-code in BL31 needs to know, or be able to determine, the location of the BL32
-(if required) and BL33 images and provide this information in response to the
-``bl31_plat_get_next_image_ep_info()`` function.
-
-.. note::
- Some platforms that configure ``RESET_TO_BL31`` might still be able to
- receive parameters in registers depending on their actual boot sequence. On
- those occasions, and in addition to ``RESET_TO_BL31``, these platforms should
- set ``RESET_TO_BL31_WITH_PARAMS`` to avoid the input registers from being
- zeroed before entering BL31.
+In this configuration, since the CPU resets to BL31, no parameters are expected
+to be passed to BL31 (see notes below for clarification).
+Instead, the platform code in BL31 needs to know, or be able to determine, the
+location of the BL32 (if required) and BL33 images and provide this information
+in response to the ``bl31_plat_get_next_image_ep_info()`` function.
Additionally, platform software is responsible for carrying out any security
initialisation, for example programming a TrustZone address space controller.
This might be done by the Trusted Boot Firmware or by platform code in BL31.
+.. note::
+ Even though RESET_TO_BL31 is designed such that BL31 is the reset BL image,
+ some platforms may wish to pass some arguments to BL31 as per the defined
+ contract between BL31 and previous bootloaders. Previous bootloaders can
+ pass arguments through registers x0 through x3. BL31 will preserve them and
+ propagate them to platform code, which will handle these arguments in an
+ IMPDEF manner.

+Introduction
+------------
+
+Power state coordination
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+A power domain topology is a logical hierarchy of power domains in a system that
+arises from the physical dependencies between power domains.
+
+Local power states describe power states for an individual node, and composite
+power states describe the combined power states for an individual node and its
+parent node(s).
+
+Entry into low-power states for a topology node above the core level requires
+coordinating its children nodes. For example, in a system with a power domain
+that encompasses a shared cache, and a separate power domain for each core that
+uses the shared cache, the core power domains must be powered down before the
+shared cache power domain can be powered down.
+
+PSCI supports two modes of power state coordination: platform-coordinated and
+OS-initiated.
+
+Platform-coordinated
+~~~~~~~~~~~~~~~~~~~~
+
+Platform-coordinated mode is the default mode of power state coordination, and
+is currently the only supported mode in TF-A.
+
+In platform-coordinated mode, the platform is responsible for coordinating power
+states, and chooses the deepest power state for a topology node that can be
+tolerated by its children.
+
+OS-initiated
+~~~~~~~~~~~~
+
+OS-initiated mode is optional.
+
+In OS-initiated mode, the calling OS is responsible for coordinating power
+states, and may request for a topology node to enter a low-power state when
+its last child enters the low-power state.
+
+Motivation
+----------
+
+There are two reasons why OS-initiated mode might be a more suitable option than
+platform-coordinated mode for a platform.
+
+Scalability
+^^^^^^^^^^^
+
+In platform-coordinated mode, each core independently selects their own local
+power states, and doesn't account for composite power states that are shared
+between cores.
+
+In OS-initiated mode, the OS has knowledge of the next wakeup event for each
+core, and can have more precise control over the entry, exit, and wakeup
+latencies when deciding if a composite power state (e.g. for a cluster) is
+appropriate. This is especially important for multi-cluster SMP systems and
+heterogeneous systems like big.LITTLE, where different processor types can have
+different power efficiencies.
+
+Simplicity
+^^^^^^^^^^
+
+In platform-coordinated mode, the OS doesn't have visibility when the last core
+at a power level enters a low-power state. If the OS wants to perform last man
+activity (e.g. powering off a shared resource when it is no longer needed), it
+would have to communicate with an API side channel to know when it can do so.
+This could result in a design smell where the platform is using
+platform-coordinated mode when it should be using OS-initiated mode instead.
+
+In OS-initiated mode, the OS can perform last man activity if it selects a
+composite power state when the last core enters a low-power state. This
+eliminates the need for a side channel, and uses the well documented API between
+the OS and the platform.
+
+Current vendor implementations and workarounds
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* STMicroelectronics
+
+ * For their ARM32 platforms, they're using OS-initiated mode implemented in
+ OP-TEE.
+ * For their future ARM64 platforms, they are interested in using OS-initiated
+ mode in TF-A.
+
+* Qualcomm
+
+ * For their mobile platforms, they're using OS-initiated mode implemented in
+ their own custom secure monitor firmware.
+ * For their Chrome OS platforms, they're using platform-coordinated mode in
+ TF-A with custom driver logic to perform last man activity.
+
+* Google
+
+ * They're using platform-coordinated mode in TF-A with custom driver logic to
+ perform last man activity.
+
+Both Qualcomm and Google would like to be able to use OS-initiated mode in TF-A
+in order to simplify custom driver logic.
+
+Requirements
+------------
+
+PSCI_FEATURES
+^^^^^^^^^^^^^
+
+PSCI_FEATURES is for checking whether or not a PSCI function is implemented and
+what its properties are.
+
+.. c:macro:: PSCI_FEATURES
+
+ :param func_id: 0x8400_000A.
+ :param psci_func_id: the function ID of a PSCI function.
+ :retval NOT_SUPPORTED: if the function is not implemented.
+ :retval feature flags associated with the function: if the function is
+ implemented.
+
+CPU_SUSPEND feature flags
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* Reserved, bits[31:2]
+* Power state parameter format, bit[1]
+
+ * A value of 0 indicates the original format is used.
+ * A value of 1 indicates the extended format is used.
+
+* OS-initiated mode, bit[0]
+
+ * A value of 0 indicates OS-initiated mode is not supported.
+ * A value of 1 indicates OS-initiated mode is supported.
+
+See sections 5.1.14 and 5.15 of the PSCI spec (DEN0022D.b) for more details.
+
+PSCI_SET_SUSPEND_MODE
+^^^^^^^^^^^^^^^^^^^^^
+
+PSCI_SET_SUSPEND_MODE is for switching between the two different modes of power
+state coordination.
+
+.. c:macro:: PSCI_SET_SUSPEND_MODE
+
+ :param func_id: 0x8400_000F.
+ :param mode: 0 indicates platform-coordinated mode, 1 indicates OS-initiated
+ mode.
+ :retval SUCCESS: if the request is successful.
+ :retval NOT_SUPPORTED: if OS-initiated mode is not supported.
+ :retval INVALID_PARAMETERS: if the requested mode is not a valid value (0 or
+ 1).
+ :retval DENIED: if the cores are not in the correct state.
+
+Switching from platform-coordinated to OS-initiated is only allowed if the
+following conditions are met:
+
+* All cores are in one of the following states:
+
+ * Running.
+ * Off, through a call to CPU_OFF or not yet booted.
+ * Suspended, through a call to CPU_DEFAULT_SUSPEND.
+
+* None of the cores has called CPU_SUSPEND since the last change of mode or
+ boot.
+
+Switching from OS-initiated to platform-coordinated is only allowed if all cores
+other than the calling core are off, either through a call to CPU_OFF or not yet
+booted.
+
+If these conditions are not met, the PSCI implementation must return DENIED.
+
+See sections 5.1.19 and 5.20 of the PSCI spec (DEN0022D.b) for more details.
+
+CPU_SUSPEND
+^^^^^^^^^^^
+
+CPU_SUSPEND is for moving a topology node into a low-power state.
+
+.. c:macro:: CPU_SUSPEND
+
+ :param func_id: 0xC400_0001.
+ :param power_state: the requested low-power state to enter.
+ :param entry_point_address: the address at which the core must resume
+ execution following wakeup from a powerdown state.
+ :param context_id: this field specifies a pointer to the saved context that
+ must be restored on a core following wakeup from a powerdown state.
+ :retval SUCCESS: if the request is successful.
+ :retval INVALID_PARAMETERS: in OS-initiated mode, this error is returned when
+ a low-power state is requested for a topology node above the core level,
+ and at least one of the node's children is in a local low-power state
+ that is incompatible with the request.
+ :retval INVALID_ADDRESS: if the entry_point_address argument is invalid.
+ :retval DENIED: only in OS-initiated mode; this error is returned when a
+ low-power state is requested for a topology node above the core level,
+ and at least one of the node's children is running, i.e. not in a
+ low-power state.
+
+In platform-coordinated mode, the PSCI implementation coordinates requests from
+all cores to determine the deepest power state to enter.
+
+In OS-initiated mode, the calling OS is making an explicit request for a
+specific power state, as opposed to expressing a vote. The PSCI implementation
+must comply with the request, unless the request is not consistent with the
+implementation's view of the system's state, in which case, the implementation
+must return INVALID_PARAMETERS or DENIED.
+
+See sections 5.1.2 and 5.4 of the PSCI spec (DEN0022D.b) for more details.
+
+Power state formats
+~~~~~~~~~~~~~~~~~~~
+
+Original format
+
+* Power Level, bits[25:24]
+
+ * The requested level in the power domain topology to enter a low-power
+ state.
+
+* State Type, bit[16]
+
+ * A value of 0 indicates a standby or retention state.
+ * A value of 1 indicates a powerdown state.
+
+* State ID, bits[15:0]
+
+ * Field to specify the requested composite power state.
+ * The state ID encodings must uniquely describe every possible composite
+ power state.
+ * In OS-initiated mode, the state ID encoding must allow expressing the
+ power level at which the calling core is the last to enter a powerdown
+ state.
+
+Extended format
+
+* State Type, bit[30]
+* State ID, bits[27:0]
+
+Races in OS-initiated mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In OS-initiated mode, there are race windows where the OS's view and
+implementation's view of the system's state differ. It is possible for the OS to
+make requests that are invalid given the implementation's view of the system's
+state. For example, the OS might request a powerdown state for a node from one
+core, while at the same time, the implementation observes that another core in
+that node is powering up.
+
+To address potential race conditions in power state requests:
+
+* The calling OS must specify in each CPU_SUSPEND request the deepest power
+ level for which it sees the calling core as the last running core (last man).
+ This is required even if the OS doesn't want the node at that power level to
+ enter a low-power state.
+* The implementation must validate that the requested power states in the
+ CPU_SUSPEND request are consistent with the system's state, and that the
+ calling core is the last core running at the requested power level, or deny
+ the request otherwise.
+
+See sections 4.2.3.2, 6.2, and 6.3 of the PSCI spec (DEN0022D.b) for more
+details.
+
+Caveats
+-------
+
+CPU_OFF
+^^^^^^^
+
+CPU_OFF is always platform-coordinated, regardless of whether the power state
+coordination mode for suspend is platform-coordinated or OS-initiated. If all
+cores in a topology node call CPU_OFF, the last core will power down the node.
+
+In OS-initiated mode, if a subset of the cores in a topology node has called
+CPU_OFF, the last running core may call CPU_SUSPEND to request a powerdown state
+at or above that node's power level.
+
+See section 5.5.2 of the PSCI spec (DEN0022D.b) for more details.
+
+Implementation
+--------------
+
+Current implementation of platform-coordinated mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Platform-coordinated is currently the only supported power state coordination
+mode in TF-A.
+
+The functions of interest in the ``psci_cpu_suspend`` call stack are as follows:
+
+* ``psci_validate_power_state``
+
+ * This function calls a platform specific ``validate_power_state`` handler,
+ which takes the ``power_state`` parameter, and updates the ``state_info``
+ object with the requested states for each power level.
+
+* ``psci_find_target_suspend_lvl``
+
+ * This function takes the ``state_info`` object containing the requested power
+ states for each power level, and returns the deepest power level that was
+ requested to enter a low power state, i.e. the target power level.
+
+* ``psci_do_state_coordination``
+
+ * This function takes the target power level and the ``state_info`` object
+ containing the requested power states for each power level, and updates the
+ ``state_info`` object with the coordinated target power state for each
+ level.
+
+* ``pwr_domain_suspend``
+
+ * This is a platform specific handler that takes the ``state_info`` object
+ containing the target power states for each power level, and transitions
+ each power level to the specified power state.
+
+Proposed implementation of OS-initiated mode
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To add support for OS-initiated mode, the following changes are proposed:
+
+* Add a boolean build option ``PSCI_OS_INIT_MODE`` for a platform to enable
+ optional support for PSCI OS-initiated mode. This build option defaults to 0.
+
+.. note::
+
+ If ``PSCI_OS_INIT_MODE=0``, the following changes will not be compiled into
+ the build.
+
+* Update ``psci_features`` to return 1 in bit[0] to indicate support for
+ OS-initiated mode for CPU_SUSPEND.
+* Define a ``suspend_mode`` enum: ``PLAT_COORD`` and ``OS_INIT``.
+* Define a ``psci_suspend_mode`` global variable with a default value of
+ ``PLAT_COORD``.
+* Implement a new function handler ``psci_set_suspend_mode`` for
+ PSCI_SET_SUSPEND_MODE.
+* Since ``psci_validate_power_state`` calls a platform specific
+ ``validate_power_state`` handler, the platform implementation should populate
+ the ``state_info`` object based on the state ID from the given ``power_state``
+ parameter.
+* ``psci_find_target_suspend_lvl`` remains unchanged.
+* Implement a new function ``psci_validate_state_coordination`` that ensures the
+ request satisfies the following conditions, and denies any requests
+ that don't:
+
+ * The requested power states for each power level are consistent with the
+ system's state
+ * The calling core is the last core running at the requested power level
+
+ This function differs from ``psci_do_state_coordination`` in that:
+
+ * The ``psci_req_local_pwr_states`` map is not modified if the request were to
+ be denied
+ * The ``state_info`` argument is never modified since it contains the power
+ states requested by the calling OS
+
+* Update ``psci_cpu_suspend_start`` to do the following:
+
+ * If ``PSCI_SUSPEND_MODE`` is ``PLAT_COORD``, call
+ ``psci_do_state_coordination``.
+ * If ``PSCI_SUSPEND_MODE`` is ``OS_INIT``, call
+ ``psci_validate_state_coordination``. If validation fails, propagate the
+ error up the call stack.
+
+* Update the return type of the platform specific ``pwr_domain_suspend``
+ handler from ``void`` to ``int``, to allow the platform to optionally perform
+ validations based on hardware states.

+
+OS-initiated mode was able to scale better than platform-coordinated mode for

-based on the data flow diagram and potential threat mitigations.
+As the TF-A codebase is highly configurable to allow tailoring it best for each

+is not necessarily the best approach. Instead, we provide a collection of
+documents which, together, form the project's threat model. These are
+articulated around a core document, called the :ref:`Generic Threat Model`,
+which focuses on the most common configuration we expect to see. The other
+documents typically focus on specific features not covered in the core document.
+
+As the TF-A codebase evolves and new features get added, these threat model
+documents will be updated and extended in parallel to reflect at best the
+current status of the code from a security standpoint.

+ .. note::
+
+ Although our aim is eventually to provide threat model material for all
