-Exception Handlers
-==================
-
-CPU exceptions are the mechanism by which various execution and memory system
-errors are handled. When an exception occurs, Freedom Metal will call the
-corresponding exception handler function, if one has been registered by the
-application.
-
-Initializing the CPU
---------------------
-
-When the user application enters the ``main()`` function, the Freedom Metal
-framework has not yet performed the initialization necessary to register
-exception handlers. If this initialization is not performed before an exception
-occurs, any exception will cause the CPU to spin in a tight loop until reset.
-
-To initialize the Freedom Metal exception handlers, initialize CPU interrupts:
-
-.. code-block:: C
-
- struct metal_cpu *cpu0 = metal_get_cpu(0);
- if(!cpu) {
- /* There was an error acquiring the CPU hart 0 handle */
- }
-
- struct metal_interrupt *cpu_int = metal_cpu_interrupt_controller(cpu0);
- if(!cpu_int) {
- /* There was an error acquiring the CPU interrupt controller */
- }
-
- metal_interrupt_init(cpu_int);
-
-The Freedom Metal interrupt API is further documented in :doc:`/devguide/interrupts`
-and :doc:`/apiref/interrupt`.
-
-Defining an Exception Handler
------------------------------
-
-Exception handlers must conform to the following function signature:
-
-.. doxygentypedef:: metal_exception_handler_t
- :project: metal
- :no-link:
-
-Therefore, an example exception handler might look like:
-
-.. code-block:: C
-
- void my_exception_handler(struct metal_cpu *cpu, int ecode) {
- /* Contents of handler */
- }
-
-Registering an Exception Handler
---------------------------------
-
-Exception handlers are registered with a given CPU hart for an individual exception
-code.
-
-.. code-block:: C
-
- /* CPU Hart 0's interrupt controller must be initialized
- * if it is not already */
- struct metal_cpu *cpu0 = metal_get_cpu(0);
-
- int rc = metal_cpu_exception_register(cpu0,
- <my_ecode>, /* Set to your desired value */
- my_exception_handler);
- if(rc != 0) {
- /* Failed to register exception handler */
- }
-
-A single exception handler may be used for multiple exception codes. For this reason,
-exception handlers receive the exception code as the ``ecode`` parameter and may use
-this to determine how to handle the exception.
-
-Returing Execution after a Faulting Instruction
------------------------------------------------
-
-The default behavior of a RISC-V CPU is to return execution to the faulting instruction.
-If this is not the desired behavior, execution can be returned to the instruction after
-the faulting instruction using the following method:
-
-.. code-block:: C
-
- void return_after_fault(struct metal_cpu *cpu, int ecode)
- {
- /* Get the faulting instruction address */
- uintptr_t epc = metal_cpu_get_exception_pc(cpu);
-
- /* Get the length of the faulting instruction */
- size_t len = metal_cpu_get_instruction_length(cpu, epc);
-
- /* Advance stored exception program counter by the
- * instruction length */
- metal_cpu_set_exception_pc(cpu, epc + len);
- }
-
-Additional Documentation
-------------------------
-
-Additional documentation for the exception handler API can be found in :doc:`The CPU API Reference </apiref/cpu>`.

-FE310-G00 PLL
-=============
-
-On targets with a PLL compatible with the FE310-G000 SoC, the PLL is configured
-at program initialization with a constructor. This PLL sets the clock frequency
-of the RISC-V CPU, and users of Freedom Metal who wish to set a specific clock
-rate can use Freedom Metal to request that the PLL take on a certain output rate.
-
-In the DeviceTree for your target, there should be a node like the following
-(example taken from the SiFive HiFive1):
-
-.. code-block:: DeviceTree
-
- hfclk: clock@4 {
- compatible = "sifive,fe310-g000,pll";
- clocks = <&hfxoscout &hfroscout>;
- clock-names = "pllref", "pllsel0";
- reg = <&prci 0x8 &prci 0xc>;
- reg-names = "config", "divider";
- clock-frequency = <16000000>;
- };
-
-The ``clock-frequency`` property of the node sets the requested clock rate of
-the FE310-G000 PLL. The PLL driver will attempt to configure the PLL to achieve
-this clock rate.
-
-Users should note that the FE310-G000 PLL only supports certain input/output
-clock rate ratios, and so the effective output rate of the PLL may differ from
-the requested rate.
+++ /dev/null
-Interrupt Handlers
-==================
-
-The Interrupt Heirarchy
------------------------
-
-Freedom Metal conceptualizes interrupts as a heirarchy of interrupt controllers.
-This heirarchy is established by the interrupt heirarchy of the target platform
-itself. Presently, the interrupt heirarchy for a given platform is best documented
-by the target's DeviceTree representation, which can be found in
-``bsp/<target-name>/design.dts``.
-
-In Freedom Metal, the heirarchy is a tree. The nodes of the tree consist of
-``struct metal_interrupt``:
-
-.. doxygenstruct:: metal_interrupt
- :project: metal
-
-And the vertices of the tree consist of interrupt ``id``.
-
-.. digraph:: int_heirarchy_graph
-
- cpu [label="CPU"];
- cpu_int [label="CPU Interrupt Controller", shape=box];
- timer_int [label="Timer Interrupt Controller", shape=box];
- soft_int [label="Software Interrupt Controller", shape=box];
-
- cpu -> cpu_int [label="ID = 0"];
- cpu_int -> timer_int [label="ID = timer_id"];
- cpu_int -> soft_int [label="ID = software_id"];
-
-The CPU Interrupt Controller
-----------------------------
-
-The CPU interrupt controller is the top of the interrupt heirarchy. It must be
-initialized before any other interrupt controllers are initialized. In example:
-
-.. code-block:: C
-
- struct metal_cpu *cpu0 = metal_get_cpu(0);
- if(!cpu) {
- /* Unable to get CPU handle */
- }
- struct metal_interrupt *cpu_int = metal_cpu_interrupt_controller(cpu0);
- if(!cpu_int) {
- /* Unable to get CPU interrupt handle */
- }
- metal_interrupt_init(cpu_int);
-
-The CPU interrupt must be enabled for the CPU to receive any interrupts, and any
-enabled interrupts can be masked by disabling the CPU interrupt.
-
-.. code-block:: C
-
- int rc = 0;
-
- /* Enable the CPU interrupt */
- rc = metal_interrupt_enable(cpu_int, 0);
- if(rc != 0) {
- /* Failed to enable the CPU interrupt */
- }
-
- /* Disable the CPU interrupt */
- rc = metal_interrupt_disable(cpu_int, 0);
- if(rc != 0) {
- /* Failed to disable the CPU interrupt */
- }
-
-Interrupt Handlers
-------------------
-
-Interrupt handlers must conform to the following function signature:
-
-.. doxygentypedef:: metal_interrupt_handler_t
- :project: metal
-
-Therefore, an interrupt handler might look like:
-
-.. code-block:: C
-
- void my_interrupt_handler(int id, void *priv_data) {
- /* Contents of handler */
- }
-
-Registering an Interrupt Handler
---------------------------------
-
-Interrupt handlers are registered with the interrupt controller for the interrupt
-they are servicing. For example, if we want to register a CPU timer interrupt:
-
-.. code-block:: C
-
- struct metal_interrupt *timer_int = metal_cpu_timer_interrupt_controller(cpu0);
- if(!timer_int) {
- /* Failed to get timer interrupt controller */
- }
- metal_interrupt_init(timer_int);
-
- int timer_id = metal_cpu_timer_get_interrupt_id(cpu0);
-
- int rc = metal_interrupt_register_handler(timer_int, timer_id, my_interrupt_handler, cpu0);
- if(rc != 0) {
- /* Failed to register interrupt handler */
- }
-
-Additional Documentation
-------------------------
-
-Additional documentation for the interrupt handler API can be found in
-:doc:`the CPU API reference </apiref/cpu>` and
-:doc:`the Interrupt API reference </apiref/interrupt>`.

-Instruction Tightly Integrated Memory
-=====================================
-
-The Instruction Tightly Integrated Memory (ITIM) is an optional feature
-on certain SiFive RISC-V CPUs. The ITIM is a memory device which is
-optimized in the CoreIP memory heirarchy to provide low-latency
-access to instruction memory.
-
-Freedom Metal provides the ability to designate functions to run out of
-the ITIM by decorating the functions with the following "decorator":
-
-.. doxygendefine:: METAL_PLACE_IN_ITIM
- :project: metal
-
-For example:
-
-.. code-block:: C
-
- METAL_PLACE_IN_ITIM
- void my_itim_func() {
- /* This code will run out of the ITIM */
- }
-
-Caveats
--------
-The ``METAL_PLACE_IN_ITIM`` decorator tells the toolchain to link the
-decorated function into the ITIM memory. However, compiler optimizations
-such as function inlining may cause execution to never transfer to
-instructions fetched from the ITIM.
-
-If this compiler optimization is not desired, one workaround is to
-tell the compiler to not inline the function:
-
-.. code-block:: C
-
- __attribute__((noinline))
- METAL_PLACE_IN_ITIM
- void my_itim_func() {
- /* This code will run out of the ITIM */
- }

-Physical Memory Protection
-==========================
-
-Physical Memory Protection (PMP) is a part of the RISC-V Privileged Architecture
-Specification which discribes the interface for a standard RISC-V memory
-protection unit.
-
-The PMP defines a finite number of PMP regions which can be individually configured
-to enforce access permissions to a range of addresses in memory. Each PMP region
-is configurable with the following options:
-
-.. doxygenstruct:: metal_pmp_config
- :project: metal
- :members:
- :no-link:
-
-Initializing the PMP
---------------------
-
-All PMP-related functions first depend on having a handle to the PMP device:
-
-.. code-block:: C
-
- struct metal_pmp *pmp = metal_pmp_get_device();
- if(!pmp) {
- /* Failed to get PMP device handle */
- }
-
-PMP initialization is optional and has the effect of disabling all PMP regions,
-if possible:
-
-.. code-block:: C
-
- metal_pmp_init(pmp);
-
-The number of PMP regions available can be retrieved from the PMP device handle:
-
-.. doxygenstruct:: metal_pmp
- :project: metal
- :members:
- :no-link:
-
-Configuring a PMP Region
-------------------------
-
-Freedom Metal has a set of APIs for configuring a PMP region. The most generic of these
-is
-
-.. doxygenfunction:: metal_pmp_set_region
- :project: metal
-
-This function allows for the configuration of all PMP region settings.
-
-Additional APIs are provided for granularly changing individual PMP region settings.
-For example:
-
-.. doxygenfunction:: metal_pmp_set_address
- :project: metal
- :no-link:
-.. doxygenfunction:: metal_pmp_lock
- :project: metal
- :no-link:
-.. doxygenfunction:: metal_pmp_set_writeable
- :project: metal
- :no-link:
-
-Additional documentation for this API is provided in :doc:`the PMP API reference </apiref/pmp>`.
-
-The RISC-V specification allows implementation of PMP to hard-wire the configuration
-values of PMP regions. In these cases, attempts to configure these PMP regions will
-fail.
-
-Handling PMP Access Faults
---------------------------
-
-Attempted memory accesses which the PMP is configured to prevent trigger a
-CPU exception. These exceptions can be handled by installing a CPU exception
-handler for exception codes related to memory access faults.
-
-Additional documentation about creating and registering exception handlers can
-be found in :doc:`the Exception Handlers Developer Guide </devguide/exceptions>`.
-
-Additional Documentation
-------------------------
-
-Additional documentation about the Physical Memory Protection system and fault
-handling on RISC-V systems can be found in
-`The RISC-V Privileged ISA Specification v1.10 <https://riscv.org/specifications/privileged-isa/>`_.

-Standard I/O
-============
-
-Freedom Metal integrates with libc ``STDOUT`` to provide virtual terminal support.
-The default ``STDOUT`` device is the first UART serial peripheral on the target.
-If no UART serial peripheral is present, such as in the case of SiFive CoreIP
-test harnesses, then the bytes sent to ``STDOUT`` are dropped.
-
-Hello World
------------
-
-Using the virtual terminal with Freedom Metal is exactly what you might expect:
-
-.. code-block:: C
- :linenos:
-
- #include <stdio.h>
-
- int main(void) {
- printf("Hello, world!");
-
- return 0;
- }
-

-Introduction to Freedom Metal
-=============================
-
-What is Freedom Metal?
-----------------------
-
-Freedom Metal enables portable, bare-metal application development for all of
-SiFive's RISC-V IP, FPGA evaluation targets, and development boards.
-
-Freedom Metal provides:
- - A bare-metal C application environment
- - An API for controlling CPU features and peripherals
- - The ability to retarget to any SiFive RISC-V product
-
-This makes Freedom Metal suitable for:
- - Writing portable hardware tests
- - Bootstrapping bare metal application development
- - A RISC-V hardware abstraction layer
- - And more!
-
-
-How Do I Use Freedom Metal?
----------------------------
-
-The best way to get started writing applications with Freedom Metal is to use
-the `SiFive Freedom E SDK`_ which bundles the build scripts and configuration
-necessary to use Freedom Metal with SiFive's standard evaluation products.
-
-If you prefer working with an Integrated Development Environment (IDE),
-`SiFive Freedom Studio`_ comes packaged with a prebuilt toolchain and the same
-Freedom Metal examples from Freedom E SDK.

-<h1>Exception Handlers<a class="headerlink" href="#exception-handlers" title="Permalink to this headline">¶</a></h1>
-<p>CPU exceptions are the mechanism by which various execution and memory system
-errors are handled. When an exception occurs, Freedom Metal will call the
-corresponding exception handler function, if one has been registered by the
-application.</p>
-<div class="section" id="initializing-the-cpu">
-<h2>Initializing the CPU<a class="headerlink" href="#initializing-the-cpu" title="Permalink to this headline">¶</a></h2>
-<p>When the user application enters the <code class="docutils literal notranslate"><span class="pre">main()</span></code> function, the Freedom Metal
-framework has not yet performed the initialization necessary to register
-exception handlers. If this initialization is not performed before an exception
-occurs, any exception will cause the CPU to spin in a tight loop until reset.</p>
-<p>To initialize the Freedom Metal exception handlers, initialize CPU interrupts:</p>

-<h1>FE310-G00 PLL<a class="headerlink" href="#fe310-g00-pll" title="Permalink to this headline">¶</a></h1>
-<p>On targets with a PLL compatible with the FE310-G000 SoC, the PLL is configured
-at program initialization with a constructor. This PLL sets the clock frequency
-of the RISC-V CPU, and users of Freedom Metal who wish to set a specific clock
-rate can use Freedom Metal to request that the PLL take on a certain output rate.</p>
-<p>In the DeviceTree for your target, there should be a node like the following
-(example taken from the SiFive HiFive1):</p>
-<div class="highlight-DeviceTree notranslate"><div class="highlight"><pre><span></span>hfclk: clock@4 {
- compatible = "sifive,fe310-g000,pll";
- clocks = <&hfxoscout &hfroscout>;
- clock-names = "pllref", "pllsel0";
- reg = <&prci 0x8 &prci 0xc>;
- reg-names = "config", "divider";
- clock-frequency = <16000000>;
-};
-</pre></div>
-</div>
-<p>The <code class="docutils literal notranslate"><span class="pre">clock-frequency</span></code> property of the node sets the requested clock rate of
-the FE310-G000 PLL. The PLL driver will attempt to configure the PLL to achieve
-this clock rate.</p>
-<p>Users should note that the FE310-G000 PLL only supports certain input/output
-clock rate ratios, and so the effective output rate of the PLL may differ from
-the requested rate.</p>

-<h1>Instruction Tightly Integrated Memory<a class="headerlink" href="#instruction-tightly-integrated-memory" title="Permalink to this headline">¶</a></h1>
-<p>The Instruction Tightly Integrated Memory (ITIM) is an optional feature
-on certain SiFive RISC-V CPUs. The ITIM is a memory device which is
-optimized in the CoreIP memory heirarchy to provide low-latency
-access to instruction memory.</p>
-<p>Freedom Metal provides the ability to designate functions to run out of
-the ITIM by decorating the functions with the following “decorator”:</p>
-<dl class="macro">
-<dt id="c.METAL_PLACE_IN_ITIM">
-<span class="target" id="itim_8h_1adc7154309c0e245ae246c435665eebb6"></span><code class="descname">METAL_PLACE_IN_ITIM</code><a class="headerlink" href="#c.METAL_PLACE_IN_ITIM" title="Permalink to this definition">¶</a></dt>
-<dd><p>Link a function into the ITIM. </p>
-<p>Link a function into the ITIM (Instruction Tightly Integrated Memory) if the ITIM is present on the target device. </p>
-</dd></dl>
-
-<p>For example:</p>
-<div class="highlight-C notranslate"><div class="highlight"><pre><span></span><span class="n">METAL_PLACE_IN_ITIM</span>
-<span class="kt">void</span> <span class="nf">my_itim_func</span><span class="p">()</span> <span class="p">{</span>

-</pre></div>
-</div>
-<div class="section" id="caveats">
-<h2>Caveats<a class="headerlink" href="#caveats" title="Permalink to this headline">¶</a></h2>
-<p>The <code class="docutils literal notranslate"><span class="pre">METAL_PLACE_IN_ITIM</span></code> decorator tells the toolchain to link the
-decorated function into the ITIM memory. However, compiler optimizations
-such as function inlining may cause execution to never transfer to
-instructions fetched from the ITIM.</p>
-<p>If this compiler optimization is not desired, one workaround is to
-tell the compiler to not inline the function:</p>

-# MEE Specification
-
-The MEE is designed to provide a source-level compatibility for
-bare-metal code between platforms. This specification defines the
-publicly available API. The intent is that this API is stable so users
-can rely on it not changing, but we're not going to make any guarantees
-about it until our 1.0.0 release.
-
-Note that the MEE does not define an ABI -- specifically that means that
-binaries will not be compatible between different versions of the MBI,
-or between different platforms.
-
-## User API
-
-The core of the MEE is a C API that is designed to allow programmers to
-write portable bare-metal embedded code.
-
-Any symbol beginning with `__mee_` is internal to the MEE and must not
-be called or defined by user code. Symbols beginning with `mee_` are
-public interfaces and can be considered to be a stable API. The best
-documentation for most of these symbols are found in the code, but some
-is listed below.
-
-### Clock Interface
-
-The clock interface allows for controlling the rate of various clocks in
-the system. Clocks are defined by a pointer to a `struct mee_clock`, the
-contents of which is implementation defined. Users of the clock
-interface must call the functions defined below in order to interact
-with a `struct mee_clock *`.
-
-Note that no mechanism for obtaining a pointer to a `struct mee_clock`
-has been defined, making it impossible to call any of these functions
-without invoking implementation-defined behavior.
-
-#### `long mee_clock_get_rate_hz(const struct mee_clock *clock)`
-
-Returns the clock rate of the given clock, in Hz.
-
-#### `long mee_clock_set_rate_hz(const struct mee_clock *clock, long hz)`
-
-Attempts to set the rate of the given clock to the given value, in Hz.
-Returns the rate the given clock was actually set to, which may be
-different than the requested rate. There are no hard requirements on
-what clock rates can be set, but it's expected that a best effort
-approach is taken to match the caller's desired clock rate.
-
-#### `void mee_clock_register_rate_change_callback(struct mee_clock *clk, int (*cb)(struct mee_clock *, void *), void *priv)`
-
-Registers a function (and an associated opaque data block) that will be
-called whenever the giver clock's rate has been changed. This function
-will be called after the driver-specific clock frequency changing code
-has returned, but before the caller of `mee_clock_set_rate_hz()` has
-been returned to.
-
-It's not guaranteed that the given clock's rate will have actually
-changed every time the given function is called, but it's guaranteed
-that the given function will be called every time the given clock's rate
-has been changed.
-
-### Timer Interface
-
-The timer interface allows for access of various timers values in
-the system. Timers are defined by a pointer to a `struct mee_timer`, the
-contents of which is implementation defined. Users of the timer
-interface must call the functions defined below in order to interact
-with a `struct mee_timer *`.
-
-Note that no mechanism for obtaining a pointer to a `struct mee_timer`
-has been defined, making it impossible to call any of these functions
-without invoking implementation-defined behavior.
-
-#### `int mee_timer_get_cyclecount(int hartid, unsigned long long *mcc)`
-
-Returns the cpu machine cycle count of a given hartid.
-
-#### `int mee_timer_get_timebase_frequency(int hartid, unsigned long long *timebase)`
-
-Returns the timebase frequency of a given hartid, s.t a time elapse duration can determined.
-For example, a timebase frequency of 1000000 (1MHz) will have each cycle count of 1s.
-
-#### `void mee_timer_init(const struct mee_timer *timer, unsigned long long timebase)`
-
-Setup the timebase frequency for a given timer, in Hz.
-
-### Power Control Interface
-
-The MEE defines a mechanism to control the power state of a given
-machine. The interface is currently quite simple: it's just the
-`mee_shutdown()` function.
-
-#### `void mee_shutdown(int code) __attribute__((noreturn))`
-
-Terminates execution of this program, attempting to pass the given code
-to whomever may be looking. The code `0` indicates success, while all
-other codes indicate failure. The exact mechanism by which execution
-terminates is implementation defined, but some examples include:
-
-* Spinning in an infinite loop.
-* Printing the return code to standard out and spinning in an infinite
- loop.
-* Toggling an external I/O to disable the power to the core.
-* Poking through a hole to the host that's providing this environment
- and indicating success or failure.
-
-### TTY Interface
-
-The MEE provides an terminal interface. This interface is designed to
-provide a simple mechanism for getting text-based data outside of the
-MEE -- in other words, it's designed to be used to implement C library
-functions like `printf()`.
-
-#### `int mee_tty_putc(unsigned char c);`
-
-Writes the given character to the default terminal, returning 0 on
-success or -1 on failure.
-
-### UART Interface
-
-The UART interface allows users of the MEE to control
-
-Note that there is no mechanism for obtaining a pointer to a `struct
-mee_uart` without invoking implementation-defined behavior, thus making
-calling any of these functions impossible.
-
-#### `int mee_uart_init(struct mee_uart *uart)`
-
-Initializes the given UART. This must be called exactly once before any
-other function on this UART can be called. It is invalid to initialize
-a UART more than once.
-
-#### `int mee_uart_putc(struct mee_uart *uart, unsigned char c)`
-
-Writes the given character to the given UART, returning 0 on success and
--1 on failure.
-
-#### `int mee_uart_getc(struct mee_uart *uart, unsigned char *c)`
-
-Reads a character from the given UART, storing it at the given character
-pointer. This returns 0 on success and -1 on failure.
-
-#### `int mee_uart_get_baud_rate(struct mee_uart *uart)`
-
-Obtains the baud rate of the given UART, or `-1` to signify an error.
-
-#### `int mee_uart_set_baud_rate(struct mee_uart *uart, int baud_rate)`
-
-Sets the baud rate of the given UART. Returns 0 on success, or -1 on
-failure. Failure to set the baud rate can render the UART unusable
-until a subsequent coll to `mee_uart_set_baud_rate()` returns success.
-
-### C Startup Interface
-
-The MEE handles entering the C library's start routine, which is defined
-by the symbol `_start`. This symbol must be defined by the C library in
-order to allow the MEE to do anything meaningful.
-
-The MEE follows the standard RISC-V bootloader ABI when calling
-`_start`:
-
-* `a0` contains the hart ID.
-* `a1` contains a pointer to the machine description. The MEE always
- sets this to NULL, as machines are described statically.
-* `a2` contains a callback that should be called from within the child
- environment after it has initialized itself.
-
-This can be described as a the C function `void _start(long hartid,
-unsigned char *dtb, void (*after_init)(void))'. Note that the MEE does
-not initialize a C environment and therefor this cannot actually be a C
-function -- for example, there may not be a stack.

-Exception Handlers
-==================
-
-CPU exceptions are the mechanism by which various execution and memory system
-errors are handled. When an exception occurs, Freedom Metal will call the
-corresponding exception handler function, if one has been registered by the
-application.
-
-Initializing the CPU
---------------------
-
-When the user application enters the ``main()`` function, the Freedom Metal
-framework has not yet performed the initialization necessary to register
-exception handlers. If this initialization is not performed before an exception
-occurs, any exception will cause the CPU to spin in a tight loop until reset.
-
-To initialize the Freedom Metal exception handlers, initialize CPU interrupts:
-
-.. code-block:: C
-
- struct metal_cpu *cpu0 = metal_get_cpu(0);
- if(!cpu) {
- /* There was an error acquiring the CPU hart 0 handle */
- }
-
- struct metal_interrupt *cpu_int = metal_cpu_interrupt_controller(cpu0);
- if(!cpu_int) {
- /* There was an error acquiring the CPU interrupt controller */
- }
-
- metal_interrupt_init(cpu_int);
-
-The Freedom Metal interrupt API is further documented in :doc:`/devguide/interrupts`
-and :doc:`/apiref/interrupt`.
-
-Defining an Exception Handler
------------------------------
-
-Exception handlers must conform to the following function signature:
-
-.. doxygentypedef:: metal_exception_handler_t
- :project: metal
- :no-link:
-
-Therefore, an example exception handler might look like:
-
-.. code-block:: C
-
- void my_exception_handler(struct metal_cpu *cpu, int ecode) {
- /* Contents of handler */
- }
-
-Registering an Exception Handler
---------------------------------
-
-Exception handlers are registered with a given CPU hart for an individual exception
-code.
-
-.. code-block:: C
-
- /* CPU Hart 0's interrupt controller must be initialized
- * if it is not already */
- struct metal_cpu *cpu0 = metal_get_cpu(0);
-
- int rc = metal_cpu_exception_register(cpu0,
- <my_ecode>, /* Set to your desired value */
- my_exception_handler);
- if(rc != 0) {
- /* Failed to register exception handler */
- }
-
-A single exception handler may be used for multiple exception codes. For this reason,
-exception handlers receive the exception code as the ``ecode`` parameter and may use
-this to determine how to handle the exception.
-
-Returing Execution after a Faulting Instruction
------------------------------------------------
-
-The default behavior of a RISC-V CPU is to return execution to the faulting instruction.
-If this is not the desired behavior, execution can be returned to the instruction after
-the faulting instruction using the following method:
-
-.. code-block:: C
-
- void return_after_fault(struct metal_cpu *cpu, int ecode)
- {
- /* Get the faulting instruction address */
- uintptr_t epc = metal_cpu_get_exception_pc(cpu);
-
- /* Get the length of the faulting instruction */
- size_t len = metal_cpu_get_instruction_length(cpu, epc);
-
- /* Advance stored exception program counter by the
- * instruction length */
- metal_cpu_set_exception_pc(cpu, epc + len);
- }
-
-Additional Documentation
-------------------------
-
-Additional documentation for the exception handler API can be found in :doc:`The CPU API Reference </apiref/cpu>`.

-FE310-G00 PLL
-=============
-
-On targets with a PLL compatible with the FE310-G000 SoC, the PLL is configured
-at program initialization with a constructor. This PLL sets the clock frequency
-of the RISC-V CPU, and users of Freedom Metal who wish to set a specific clock
-rate can use Freedom Metal to request that the PLL take on a certain output rate.
-
-In the DeviceTree for your target, there should be a node like the following
-(example taken from the SiFive HiFive1):
-
-.. code-block:: DeviceTree
-
- hfclk: clock@4 {
- compatible = "sifive,fe310-g000,pll";
- clocks = <&hfxoscout &hfroscout>;
- clock-names = "pllref", "pllsel0";
- reg = <&prci 0x8 &prci 0xc>;
- reg-names = "config", "divider";
- clock-frequency = <16000000>;
- };
-
-The ``clock-frequency`` property of the node sets the requested clock rate of
-the FE310-G000 PLL. The PLL driver will attempt to configure the PLL to achieve
-this clock rate.
-
-Users should note that the FE310-G000 PLL only supports certain input/output
-clock rate ratios, and so the effective output rate of the PLL may differ from
-the requested rate.
+++ /dev/null
-Interrupt Handlers
-==================
-
-The Interrupt Heirarchy
------------------------
-
-Freedom Metal conceptualizes interrupts as a heirarchy of interrupt controllers.
-This heirarchy is established by the interrupt heirarchy of the target platform
-itself. Presently, the interrupt heirarchy for a given platform is best documented
-by the target's DeviceTree representation, which can be found in
-``bsp/<target-name>/design.dts``.
-
-In Freedom Metal, the heirarchy is a tree. The nodes of the tree consist of
-``struct metal_interrupt``:
-
-.. doxygenstruct:: metal_interrupt
- :project: metal
-
-And the vertices of the tree consist of interrupt ``id``.
-
-.. digraph:: int_heirarchy_graph
-
- cpu [label="CPU"];
- cpu_int [label="CPU Interrupt Controller", shape=box];
- timer_int [label="Timer Interrupt Controller", shape=box];
- soft_int [label="Software Interrupt Controller", shape=box];
-
- cpu -> cpu_int [label="ID = 0"];
- cpu_int -> timer_int [label="ID = timer_id"];
- cpu_int -> soft_int [label="ID = software_id"];
-
-The CPU Interrupt Controller
-----------------------------
-
-The CPU interrupt controller is the top of the interrupt heirarchy. It must be
-initialized before any other interrupt controllers are initialized. In example:
-
-.. code-block:: C
-
- struct metal_cpu *cpu0 = metal_get_cpu(0);
- if(!cpu) {
- /* Unable to get CPU handle */
- }
- struct metal_interrupt *cpu_int = metal_cpu_interrupt_controller(cpu0);
- if(!cpu_int) {
- /* Unable to get CPU interrupt handle */
- }
- metal_interrupt_init(cpu_int);
-
-The CPU interrupt must be enabled for the CPU to receive any interrupts, and any
-enabled interrupts can be masked by disabling the CPU interrupt.
-
-.. code-block:: C
-
- int rc = 0;
-
- /* Enable the CPU interrupt */
- rc = metal_interrupt_enable(cpu_int, 0);
- if(rc != 0) {
- /* Failed to enable the CPU interrupt */
- }
-
- /* Disable the CPU interrupt */
- rc = metal_interrupt_disable(cpu_int, 0);
- if(rc != 0) {
- /* Failed to disable the CPU interrupt */
- }
-
-Interrupt Handlers
-------------------
-
-Interrupt handlers must conform to the following function signature:
-
-.. doxygentypedef:: metal_interrupt_handler_t
- :project: metal
-
-Therefore, an interrupt handler might look like:
-
-.. code-block:: C
-
- void my_interrupt_handler(int id, void *priv_data) {
- /* Contents of handler */
- }
-
-Registering an Interrupt Handler
---------------------------------
-
-Interrupt handlers are registered with the interrupt controller for the interrupt
-they are servicing. For example, if we want to register a CPU timer interrupt:
-
-.. code-block:: C
-
- struct metal_interrupt *timer_int = metal_cpu_timer_interrupt_controller(cpu0);
- if(!timer_int) {
- /* Failed to get timer interrupt controller */
- }
- metal_interrupt_init(timer_int);
-
- int timer_id = metal_cpu_timer_get_interrupt_id(cpu0);
-
- int rc = metal_interrupt_register_handler(timer_int, timer_id, my_interrupt_handler, cpu0);
- if(rc != 0) {
- /* Failed to register interrupt handler */
- }
-
-Additional Documentation
-------------------------
-
-Additional documentation for the interrupt handler API can be found in
-:doc:`the CPU API reference </apiref/cpu>` and
-:doc:`the Interrupt API reference </apiref/interrupt>`.

-Instruction Tightly Integrated Memory
-=====================================
-
-The Instruction Tightly Integrated Memory (ITIM) is an optional feature
-on certain SiFive RISC-V CPUs. The ITIM is a memory device which is
-optimized in the CoreIP memory heirarchy to provide low-latency
-access to instruction memory.
-
-Freedom Metal provides the ability to designate functions to run out of
-the ITIM by decorating the functions with the following "decorator":
-
-.. doxygendefine:: METAL_PLACE_IN_ITIM
- :project: metal
-
-For example:
-
-.. code-block:: C
-
- METAL_PLACE_IN_ITIM
- void my_itim_func() {
- /* This code will run out of the ITIM */
- }
-
-Caveats
--------
-The ``METAL_PLACE_IN_ITIM`` decorator tells the toolchain to link the
-decorated function into the ITIM memory. However, compiler optimizations
-such as function inlining may cause execution to never transfer to
-instructions fetched from the ITIM.
-
-If this compiler optimization is not desired, one workaround is to
-tell the compiler to not inline the function:
-
-.. code-block:: C
-
- __attribute__((noinline))
- METAL_PLACE_IN_ITIM
- void my_itim_func() {
- /* This code will run out of the ITIM */
- }
-
+++ /dev/null
-Physical Memory Protection
-==========================
-
-Physical Memory Protection (PMP) is a part of the RISC-V Privileged Architecture
-Specification which discribes the interface for a standard RISC-V memory
-protection unit.
-
-The PMP defines a finite number of PMP regions which can be individually configured
-to enforce access permissions to a range of addresses in memory. Each PMP region
-is configurable with the following options:
-
-.. doxygenstruct:: metal_pmp_config
- :project: metal
- :members:
- :no-link:
-
-Initializing the PMP
---------------------
-
-All PMP-related functions first depend on having a handle to the PMP device:
-
-.. code-block:: C
-
- struct metal_pmp *pmp = metal_pmp_get_device();
- if(!pmp) {
- /* Failed to get PMP device handle */
- }
-
-PMP initialization is optional and has the effect of disabling all PMP regions,
-if possible:
-
-.. code-block:: C
-
- metal_pmp_init(pmp);
-
-The number of PMP regions available can be retrieved from the PMP device handle:
-
-.. doxygenstruct:: metal_pmp
- :project: metal
- :members:
- :no-link:
-
-Configuring a PMP Region
-------------------------
-
-Freedom Metal has a set of APIs for configuring a PMP region. The most generic of these
-is
-
-.. doxygenfunction:: metal_pmp_set_region
- :project: metal
-
-This function allows for the configuration of all PMP region settings.
-
-Additional APIs are provided for granularly changing individual PMP region settings.
-For example:
-
-.. doxygenfunction:: metal_pmp_set_address
- :project: metal
- :no-link:
-.. doxygenfunction:: metal_pmp_lock
- :project: metal
- :no-link:
-.. doxygenfunction:: metal_pmp_set_writeable
- :project: metal
- :no-link:
-
-Additional documentation for this API is provided in :doc:`the PMP API reference </apiref/pmp>`.
-
-The RISC-V specification allows implementation of PMP to hard-wire the configuration
-values of PMP regions. In these cases, attempts to configure these PMP regions will
-fail.
-
-Handling PMP Access Faults
---------------------------
-
-Attempted memory accesses which the PMP is configured to prevent trigger a
-CPU exception. These exceptions can be handled by installing a CPU exception
-handler for exception codes related to memory access faults.
-
-Additional documentation about creating and registering exception handlers can
-be found in :doc:`the Exception Handlers Developer Guide </devguide/exceptions>`.
-
-Additional Documentation
-------------------------
-
-Additional documentation about the Physical Memory Protection system and fault
-handling on RISC-V systems can be found in
-`The RISC-V Privileged ISA Specification v1.10 <https://riscv.org/specifications/privileged-isa/>`_.
+++ /dev/null
-Standard I/O
-============
-
-Freedom Metal integrates with libc ``STDOUT`` to provide virtual terminal support.
-The default ``STDOUT`` device is the first UART serial peripheral on the target.
-If no UART serial peripheral is present, such as in the case of SiFive CoreIP
-test harnesses, then the bytes sent to ``STDOUT`` are dropped.
-
-Hello World
------------
-
-Using the virtual terminal with Freedom Metal is exactly what you might expect:
-
-.. code-block:: C
- :linenos:
-
- #include <stdio.h>
-
- int main(void) {
- printf("Hello, world!");
-
- return 0;

-Introduction to Freedom Metal
-=============================
-
-What is Freedom Metal?
-----------------------
-
-Freedom Metal enables portable, bare-metal application development for all of
-SiFive's RISC-V IP, FPGA evaluation targets, and development boards.
-
-Freedom Metal provides:
- - A bare-metal C application environment
- - An API for controlling CPU features and peripherals
- - The ability to retarget to any SiFive RISC-V product
-
-This makes Freedom Metal suitable for:
- - Writing portable hardware tests
- - Bootstrapping bare metal application development
- - A RISC-V hardware abstraction layer
- - And more!
-
-
-How Do I Use Freedom Metal?
----------------------------
-
-The best way to get started writing applications with Freedom Metal is to use
-the `SiFive Freedom E SDK`_ which bundles the build scripts and configuration
-necessary to use Freedom Metal with SiFive's standard evaluation products.
-
-If you prefer working with an Integrated Development Environment (IDE),
-`SiFive Freedom Studio`_ comes packaged with a prebuilt toolchain and the same
-Freedom Metal examples from Freedom E SDK.
