Or1ksim Test Suite
==================
This is the Or1ksim test suite, which is now integrated with the main Or1ksim
development package. It operates using a standard DejaGNU framework within the
GNU autoconf/automake/libtool structure.
A separate configuration file is needed for the test suite, since it uses the
OR1K tool chain, rather than the host tool chain.
At the time of writing a total of 21 tests compile run and pass.
Configuration and make files are provided for further test programs. These
come in three categories.
- Tests which compile correctly, but will not run to completion.
- Tests which compile, but will not run at all.
- Tests which will not compile correctly.
File Organization
=================
Each test program has its own directory under test-code. This builds the test
program. If necessary it copies data files to the main build/testsuite
directory.
Each test then has a DejaGNU expect script in or1ksim.tests, which loads and
runs the test. Support script procedures are in lib/or1ksim.exp.
Libraries
=========
Within the test-code there are several libraries:
support: A minimal C library.
except: Exception handling and startup code.
mc-common: A library to support the memory controller tests.
Working tests
=============
A total of 21 tests:
basic: A test or a wide range of instructions and registers.
cache: A test of the Or1ksim cache modeling
cbasic: A minimal test in C
cfg: A test of the OR1K configuration register
dhry: Dhrystone 2.1 benchmark using Or1ksim's timing facility.
dmatest: A test of DMA.
eth: A test of the Ethernet interface.
except-test: A test of OR1K exception handling
exit: A test that C program exits correctly
ext: A test of the sign extension (l.ext) instructions.
fbtest: A test of the frame buffer.
functest: A test of the C function calling interface.
flag: A test of Supervision Register (SR) flag bits.
int-test: A test of the programmable interrupt controller.
kbdtest: A test of the PS2 keyboard interface.
local-global: A test of C local and global variables.
mem-test: A simple memory test.
mmu: A test of the MMU.
mul: A test of the multiply functionality.
mycompress: A compression program.
tick: A test of the OR1K tick timer.
Tests which build, but do not run to completion
===============================================
The following tests rely on VAPI in Or1ksim, so need a client to provide test
data over TCP/IP.
acv-gpio: a test of the GPIO.
acv-uart: a test of the UART
Tests which build, but do not run at all
========================================
These tests (which are built by the make file), do not appear to run at
all. The problem is in the linker script and/or the configuration for Or1ksim.
mc-async: a test of the memory controller with asynchronous memory.
mc-dram: a test of the memory controller with DRAM.
mc-ssram: a test of the memory controller with SSRAM.
mc-sync: a test of the memory controller with synchronous memory.
uOS: a microKernel.
Tests which do not build
========================
The following test builds with a myriad of warnings.
inst-set-test: a comprehensive test of the instruction set using C.
