Add a CPU counter interface to allow access to a free-running counter.
It is useful to measure short time intervals. This can be used for
example to enable profiling of critical low-level functions.
Add two busy wait functions rtems_counter_delay_ticks() and
rtems_counter_delay_nanoseconds() implemented via the CPU counter.
Rename rtems_internal_error_description() to
rtems_internal_error_text(). Rename rtems_fatal_source_description() to
rtems_fatal_source_text(). Rename rtems_status_code_description() to
rtems_status_text(). Remove previous implementation of
rtems_status_text().
Control the help command break with the SHELL_LINES evironment variable
where the numeric value is the number of lines to break on. If the
value is 0 the output is not broken. The default is 16 lines.
Add shell documentation for the help command.
This patch includes a heavy rewrite of the chapter to have a more
structured approach to this chapter. It also changes the sectioning
to have the Data Structures be a section to themselves as a peer in the
outline with each logical area of macros in confdefs.h.
This commit deletes all RTEMS ChangeLog files. These files have been abandoned
since converting to git version control. The historical data may be recovered
by checking out any commit before this one. Most of the contents of these
ChangeLog files can also be found in the git log.
Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.
Building with a document specific prefix will require coding
in both texi2any and texi2html. It is easier to build into
a directory (e.g. $(PROJECT)/). This also fixes "make clean"
which was broken.
The 16 bit Object Id image was incorrectly rotated in the manual.
Both the 16 and 32 Object Id bit images had thin borders on the table
and the bottom line was not visible in the PDF. I tinkered with the
original drawings to add a bit more space around the tables and
manually converted the PNG to EPS using Gimp to ensure a controlled
and high quality conversion.
This was tested with texi2html-1.82-5.1.el6.noarch and
a locally built texinfo 5.0. These are completely different
implementations and require different invocations.
The Makefile dependencies appear to work but are likely not
perfect at this point. The key point is that the autoconf
probe detects which to use and responds accordingly with
preference given to texi2any.
