2000-07-26Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill5-2/+10
a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4.

2000-06-12Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine GauthierJoel Sherrill3-9/+164
<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart <Darlene.Stewart@nrc.ca> to add support for a number of very significant things: + BSPs for many variations on the Motorola MBX8xx board series + Cache Manager including initial support for m68040 and PowerPC + Rework of mpc8xx libcpu code so all mpc8xx CPUs now use same code base. + Rework of eth_comm BSP to utiltize above. John reports this works on the 821 and 860

2000-02-08Patches rtems-rc-20000204-0.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1-1/+0
that contains: * Removes remaining (now illegal) references to $(SRC) from a couple of Makefile.ams * Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in * Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR from most configure scripts, i.e. LIBCDIR becomes less visible) * Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to libbsp/*/configure.ins (A minor bug in previous implementations, which only has an impact when switching to GNU/Cygnus canonicalization) * Cleans up several bogus comments. * Removes MKLIB * Switches the version number to 4.5.0 (for testing version number handling)

Ralf Corsepius <corsepiu@faw.uni-ulm.de> that contain: * Modifications, (minor) corrections, cleanups to most existing Makefile.ams * Adds automake support to all remaining BSPs which have not yet been converted to automake. * Makefile.am for all remaining wrapup/Makefile.ams
2000-01-13POSIX message queues now include complete functionality includingJoel Sherrill2-69/+96
blocking sends when the queue is full. The SuperCore was enhanced to support blocking on send. The existing POSIX API was debugged and numerous test cases were added to psxmsgq01 by Jennifer Averett. SuperCore enhancements and resulting modifications to other APIs were done by Joel. There is one significant point of interpretation for the POSIX API. What happens to threads already blocked on a message queue when the mode of that same message queue is changed from blocking to non-blocking? We decided to unblock all waiting tasks with an EAGAIN error just as if a non-blocking version of the same operation had returned unsatisfied. This case is not discussed in the POSIX standard and other implementations may have chosen differently.

2000-01-05Added support for simple binary semaphores in addition to the highJoel Sherrill3-32/+42
power binary/mutex style semaphores already supported by RTEMS. This was done at the request of Eric Norum <eric@cls.usask.ca> in support of his effort to port EPICS to RTEMS. This change consisted of changing the nesting_allowed boolean into a lock_nesting_behavior enumerated value as well as allowing the core mutex object to optionally support ensuring that the holder of a binary semaphore released it. Finally, a more subtle enhancement was to allow the non-holder to release a priority inheritance/ceiling mutex and still allow the holding task to return to its original priority.

"mutex" and counting semaphore. This is at the request of Eric Norum and his EPICS porting effort.

1999-07-30 Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1-5/+5
The main topic is replacing the hard-coded values for HAS_MP and HAS_RDBG in custom/*.cfg with per-bsp configuration-time autoconf checks (This is the patch I had mentioned before earlier this week). CHANGES * HAS_MP removed from custom/*.cfg, replaced with configuration time autoconf check * HAS_RDBG removed from custom/*.cfg, replaced with configuration-time autoconf check * NEW: c/src/make/bsp.cfg.in, takes configuration-time checked per-bsp values (i.e. HAS_MP, HAS_RDBG), gets installed as $(prefix)/<bsp>/make/bsp.cfg * NEW: default.cfg includes bsp.cfg - this change is backward compatible. * IMPORT_SRC: apply VPATH instead for ts_386ex/i386ex subdirectory Makefile.ins * HACK: a bug in acpolish mis-handles addtions to makefile variables which are enclosed in gmake conditionals: c/src/lib/libbsp/m68k/ods68302/start302/Makefile.in * Apply inline_dir, HAS_MP and HAS_RDBG for avoiding configuration of unneeded subdirectories in various configure.in files. * Several minor changes in Makefile.ins and configure.ins, wrt. to the order of including *.cfg and defining Makefile variables APPLYING THE PATCH: patch -p1 < rtems-rc-19990709-4.diff ./autogen
