To make the documentation readable from the source I want to get rid of the substitutions for the project name an code name. This does not add any values and makes it unreadable when looking at the text files directly. It also causes some issues when people use those without actually knowing what they represent, resulting in some weird and redundant language.

Platform Configuration: basic_minuteia

######################################

Overview
|
|
********
|
|
|
|
The Zephyr Kernel uses the basic_minuteia platform configuration
|
|
to emulate the galileo platform (or something similar) running on QEMU.
|
|
It provides support for an x86 Minute IA CPU and the following devices:
|
|
|
|
* HPET
|
|
|
|
* Advanced Programmable Interrupt Controller (APIC)
|
|
|
|
* NS16550 UART
|
|
|
|
.. note::
|
|
This platform configuration makes no claims about its suitability for use
|
|
with actual galileo hardware, or any other hardware.
|
|
|
|
Supported Boards
|
|
****************
|
|
|
|
The basic_minuteia platform configuration has been tested on QEMU 2.1.
|
|
|
|
Supported Features
|
|
******************
|
|
|
|
The basic_minuteia platform configuration supports the following
|
|
hardware features:
|
|
|
|
+--------------+------------+-----------------------+
|
|
| Interface | Controller | Driver/Component |
|
|
+==============+============+=======================+
|
|
| HPET | on-chip | system clock |
|
|
+--------------+------------+-----------------------+
|
|
| APIC | on-chip | interrupt controller |
|
|
+--------------+------------+-----------------------+
|
|
| NS16550 | on-chip | serial port |
|
|
| UART | | |
|
|
+--------------+------------+-----------------------+
|
|
|
|
The kernel currently does not support other hardware features on this platform.
|
|
|
|
Interrupt Controller
|
|
====================
|
|
|
|
Refer to the :ref:`galileo`.
|
|
|
|
.. note::
|
|
The basic_minuteia platform configuration does not support PCI.
|
|
|
|
HPET System Clock Support
|
|
=========================
|
|
|
|
The basic_minuteia platform configuration uses an HPET clock frequency
|
|
of 25 MHz.
|
|
|
|
Serial Port
|
|
===========
|
|
|
|
The basic_minuteia platform configuration uses a single serial
|
|
communication channel that uses the NS16550 serial driver
|
|
operating in polling mode. To override, enable the UART_INTERRUPT_DRIVEN
|
|
Kconfig option, which allows the system to be interrupt-driven.
