NOTE: The string <release> should be replaced with
|
||||
the appropriate release number of RTEMS.
|
||||
|
||||
This file only discusses the installation of .tgz files.
|
||||
For more detailed information on the installation of RTEMS,
|
||||
refer to the Release Notes manual in the file
|
||||
/pub/rtems/releases/<release>/doc/c_or_ada/relnotes.tgz on
|
||||
lancelot.gcs.redstone.army.mil.
|
||||
|
||||
UNCOMPRESSING .tgz FILES
|
||||
===========================
|
||||
Many of the files found in this directory and its subdirectories
|
||||
are gzip'ed, tar archive files. These files have the ".tgz"
|
||||
extension. They were compressed with gzip version 1.2.4.
|
||||
|
||||
Use a command sequence similar to the following to uncompress each
|
||||
file:
|
||||
|
||||
gzcat FILE.tgz | tar xvof -
|
||||
|
||||
where FILE.tgz is the file to be installed. This procedure will
|
||||
extract the files in the archive into the current directory.
|
||||
All of the .tgz files associated with this release RTEMS will
|
||||
place their contents in a subdirectory rtems-<release> in the current
|
||||
directory.
|
||||
|
||||
If you are unsure of what is in an RTEMS archive file, then use
|
||||
the following command sequence to get a listing of the contents:
|
||||
|
||||
gzcat FILE.tgz | tar tvf -
|
||||
|
||||
NOTES:
|
||||
|
||||
(1) The "-o" option to tar is included on the tar command line
|
||||
so that the user extracting the tar archive will own the extracted
|
||||
files.
|
||||
|
||||
(2) gzcat is sometimes installed as zcat. Be warned that on many
|
||||
(most) UNIX machines, zcat is associated with compress (.Z files).
|
||||
|
||||
(3) If you do not have gzip 1.2.4, it is available from numerous sites
|
||||
including this one. Other sites include prep.ai.mit.edu and
|
||||
gatekeeper.dec.com.
|
||||
|
||||
(4) The GNU archive files included in this distribution are packaged
|
||||
exactly like they are on official GNU ftp sites. When extracting
|
||||
GNU archives, they will not extract under a rtems-<version>
|
||||
directory. They will extract themselves under a directory which
|
||||
is the name and version of the tool in question. For example,
|
||||
gcc-2.5.8.tgz will extract its contents into the subdirectory
|
||||
gcc-2.5.8.

This directory contains the PDL for the RTEMS executive.
|
||||
|
||||
Ada versus C
|
||||
============
|
||||
|
||||
There are two implementations of RTEMS in this source tree --
|
||||
in Ada and in C. These two implementations are functionally
|
||||
and structurally equivalent. The C implementation follows
|
||||
the packaging conventions and hiearchical nature of the Ada
|
||||
implementation. In addition, a style has been followed which
|
||||
allows one to easily find the corresponding Ada and C
|
||||
implementations.
|
||||
|
||||
File names in C and code placement was carefully designed to insure
|
||||
a close mapping to the Ada implementation. The following file name
|
||||
extensions are used:
|
||||
|
||||
.adb - Ada body
|
||||
.ads - Ada specification
|
||||
.adp - Ada body requiring preprocessing
|
||||
.inc - include file for .adp files
|
||||
|
||||
.c - C body (non-inlined routines)
|
||||
.inl - C body (inlined routines)
|
||||
.h - C specification
|
||||
|
||||
In the executive source, XYZ.c and XYZ.inl correspond directly to a
|
||||
single XYZ.adb or XYZ.adp file. A .h file corresponds directly to
|
||||
the .ads file. There are only a handful of .inc files in the
|
||||
Ada source and these are used to insure that the desired simple
|
||||
inline textual expansion is performed. This avoids scoping and
|
||||
calling convention side-effects in carefully constructed tests
|
||||
which usually test context switch behavior.
|
||||
|
||||
In addition, in Ada code and data name references are always fully
|
||||
qualified as PACKAGE.NAME. In C, this convention is followed
|
||||
by having the package name as part of the name itself and using a
|
||||
capital letter to indicate the presence of a "." level. So we have
|
||||
PACKAGE.NAME in Ada and _Package_Name in C. The leading "_" in C
|
||||
is used to avoid naming conflicts between RTEMS and user variables.
|
||||
By using these conventions, one can easily compare the C and Ada
|
||||
implementations.
|
||||
|
||||
The most noticeable difference between the C and Ada83 code is
|
||||
the inability to easily obtain a "typed pointer" in Ada83.
|
||||
Using the "&" operator in C yields a pointer with a specific type.
|
||||
The 'Address attribute is the closest feature in Ada83. This
|
||||
returns a System.Address and this must be coerced via Unchecked_Conversion
|
||||
into an access type of the desired type. It is easy to view
|
||||
System.Address as similar to a "void *" in C, but this is not the case.
|
||||
A "void *" can be assigned to any other pointer type without an
|
||||
explicit conversion.
|
||||
|
||||
The solution adopted to this problem was to provide two routines for
|
||||
each access type in the Ada implementation -- one to convert from
|
||||
System.Address to the access type and another to go the opposite
|
||||
direction. This results in code which accomplishes the same thing
|
||||
as the corresponding C but it is easier to get lost in the clutter
|
||||
of the apparent subprogram invocations than the "less bulky"
|
||||
C equivalent.
|
||||
|
||||
A related difference is the types which are only in Ada which are used
|
||||
for pointers to arrays. These types do not exist and are not needed
|
||||
in the C implementation.

RTEMS was developed by On-Line Applications Research (OAR) under
|
||||
contract to the U.S. Army Missile Command. Other than the
|
||||
contributions listed in this document, all code and documentation
|
||||
was developed by OAR for the Army.
|
||||
|
||||
The RTEMS project would like to thank those who have made
|
||||
contributions to the project. Together we make RTEMS a
|
||||
much better product.
|
||||
|
||||
The following persons/organizations have made contributions:
|
||||
|
||||
+ Dr. Mikhail (Misha) Savitski (mms@eiscathq.irf.se) of the EISCAT Scientific
|
||||
Association submitted the BSP and other miscellaneous support for the
|
||||
Motorola MVME162 (M68040LC CPU) VMEbus single board computer.
|
||||
|
||||
+ Division Inc. of Chapel Hill, NC for sponsoring On-Line Applications
|
||||
Research to port RTEMS to the Hewlett-Packard PA-RISC architecture (V1.1)
|
||||
and the addition of HP-UX as a development host. Tony Bennett
|
||||
(tbennett@divnc.com) was assisted in this effort by Joel Sherrill
|
||||
(jsherril@redstone.army.mil). Tony also deserves a big pat on the
|
||||
back for contributing significantly to the overall organization
|
||||
of the development environment and directory structure. RTEMS
|
||||
is much easier to build because of Tony.
|
||||
|
||||
+ Greg Allen of Division Inc. of Chapel Hill, NC for
|
||||
porting RTEMS to HP-UX. This port treats a UNIX computer as simply
|
||||
another RTEMS target processor. This port can be used to develop
|
||||
and test code which will ultimately run on the embedded platform.
|
||||
|
||||
+ Doug McBride (mcbride@rodin.colorado.edu) of the Colorado Space Grant
|
||||
College at the University of Colorado at Boulder submitted the BSP
|
||||
for the Motorola IDP board (M68EC040 CPU) single board computer. The
|
||||
BSP leverages heavily off of the existing RTEMS BSP framework, the
|
||||
examples in the back of the IDP user's manual, and the libgloss example
|
||||
support for the IDP board from the newlib/libgloss distribution.
|
||||
|
||||
Finally, the RTEMS project would like to thank those who have contributed
|
||||
to the other free software efforts which RTEMS utilizes. The primary RTEMS
|
||||
development environment is from the Free Software Foundation (the GNU
|
||||
project). The "newlib" C library was put together by Cygnus and is
|
||||
a collaboration of the efforts of numerous individuals and organizations.
|
||||
|
||||
We would like to see your name here. BSPs and ports are always welcome.
|
||||
Useful libraries which support RTEMS applications are also an important
|
||||
part of providing a strong foundation for the development of real-time
|
||||
embedded applications and are welcome as submission.

This is the list of outstanding problems in this release.
|
||||
|
||||
1. The m68000 support is not complete. Someone with target hardware
|
||||
needs to complete the missing gaps. Look for ifdef's based on the
|
||||
M68K_* macros defined in c/make/cpu/m68k.cfg. Most of the code
|
||||
is present but none of it is tested. An attempt was made to insert
|
||||
"#warnings" preprocessor directives in the appropriate places.
|
||||
So these are a good starting spot.
|
||||
|
||||
2. The only i960 family member tested is the CA. No support for the
|
||||
floating point support found in other family members is present.
|
||||
This also implies that RTEMS may "think" of something as generic
|
||||
across the i960 family when in fact it is specific to the CA.
|
||||
|
||||
3. The __read() system call in all of the BSPs using single
|
||||
character input/output needs to be smarter. The following
|
||||
issues need to be addressed:
|
||||
|
||||
+ echoing of characters on input
|
||||
+ CR/NL echoing
|
||||
+ backspaces
|
||||
+ tabs
|
||||
|
||||
4. Solaris 2.3 port notes:
|
||||
|
||||
+ Some of the tests run correctly when run interactively but
|
||||
the screen and output do not match when the output is
|
||||
redirected to a file.
|
||||
|
||||
+ sometimes a stray SIGALRM is reported as spfatal completes.
|
||||
|
||||
5. Some of the tests may execute correctly and not produce the exact
|
||||
ordering of lines in the screen file. This appears to be a combination
|
||||
of a number of factors including buffering, processor speed, IO
|
||||
device overhead, and clock interrupt rate.

In the directory "update_tools", there are a set of tools to aid in
|
||||
making the application source changes necessary to address some
|
||||
of the changes in the RTEMS API between release 3.1.0 and 3.2.0.
|
||||
|
||||
The primary change addressed by these tools is the addition of
|
||||
"rtems_" or "RTEMS_" as a prefix on EVERY user visible RTEMS
|
||||
provided constant and routine. The primary factor in the decision
|
||||
to make such a sweeping change was conflicts between the

the RTEMS and POSIX API's.

Requires bash or ksh.
|
||||
|
||||
rcs-clean
|
||||
deletes all files from the current directory that can be
|
||||
re-created from RCS. Careful to not delete locked files.
|
||||
May be used by 'gmake clobber'
|
||||
|
||||
lock-directory
|
||||
unlock-directory
|
||||
traverse a directory structure making it unwritable.
|
||||
Useful to keep people from accidentally overwriting
|
||||
"released" trees if they get confused about which
|
||||
module they have loaded.
|
||||
|
||||
rtems-glom
|
||||
glom together all the rtems libraries in order to simplify
|
||||
the link line used by applications.
|
||||
Produces rtems.rel.
|
||||
Not used by the RTEMS src tree at all.
|
||||
Strictly optional.

|
||||
install-if-change
|
||||
Smart install script that also can append suffixes as it
|
||||
installs (suffixes used for debug and profile variants).
|
||||
Requires bash or ksh.
|
||||
|
||||
rcs-clean
|
||||
deletes all files from the current directory that can be
|
||||
re-created from RCS. Careful to not delete locked files.
|
||||
May be used by 'gmake clobber'
|
||||
|
||||
lock-directory
|
||||
unlock-directory
|
||||
traverse a directory structure making it unwritable.
|
||||
Useful to keep people from accidentally overwriting
|
||||
"released" trees if they get confused about which
|
||||
module they have loaded.
|
||||
|
||||
rtems-glom
|
||||
glom together all the rtems libraries in order to simplify
|
||||
the link line used by applications.
|
||||
Produces rtems.rel.
|
||||
Not used by the RTEMS src tree at all.
|
||||

Overview of newlib support (newlib is from CYGNUS)
|
||||
Each task can have its own libc state including:
|
||||
open stdio files
|
||||
strtok
|
||||
multi precision arithmetic state
|
||||
etc.
|
||||
|
||||
This is implemented by a reentrancy data structure for each task.
|
||||
|
||||
When a task is "started" (in RTEMS sense) the reentrancy structure
|
||||
is allocated. Its address is stored in notepad[NOTEPAD_LAST].
|
||||
|
||||
When task is switched to, the value of global variable _impure_ptr
|
||||
is changed to the value of the new tasks reentrancy structure.
|
||||
|
||||
When a task is deleted
|
||||
atexit() processing (for that task) happens
|
||||
task's stdio buffers are flushed
|
||||
|
||||
When exit(3) is called
|
||||
calling task's atexit processing done
|
||||
global libc state atexit processing done
|
||||
(this will include any atexit routines installed by drivers)
|
||||
executive is shutdown
|
||||
causes a context switch back to bsp land
|
||||
|
||||
|
||||
NOTE:
|
||||
libc extension are installed by bsp_libc_init()
|
||||
iff we are using clock interrupts.
|
||||
This hack is necessary to allow the tmtests to avoid
|
||||
timing the extensions.
