2000-06-29This is the initial addition of the port of RTEMS to theJoel Sherrill16-0/+2025
Hitachi H8 family. This port was done by Philip Quaife <philip@qs.co.nz> of Q Solutions and sponsored by Comnet Technologies Ltd. The port was done based on RTEMS 3.5.1 to a Hitach H8300H. The port was updated to RTEMS 4.5 style Makefiles/configure by Joel Sherrill <joel@OARcorp.com>. While doing this Joel added support for the h8300-rtems to binutils, gcc, newlib, and gdb. NOTE: Philip submitted a BSP for a Hitachi evaluation board which is being merged as a separate entity.
2000-06-29Added RTEMS_CPU_HAS_16_BIT_ADDRESSES constant to disable codeJoel Sherrill1-0/+4
that breaks when the target has 16 bit address space. One of the H8 multilibs is a 16-bit address space CPU. When a real attempt is made to support this CPU model, the code that assumes an address is 32 bits will have to change. This constant is probably not flagging all impacted code.

2000-06-15Patch rtems-rc-20000615-1-cvs.diff from Ralf CorsepiusJoel Sherrill1-1/+1
<corsepiu@faw.uni-ulm.de> to fix a bad file reference.
2000-06-14Patch rtems-rc-20000614-sh.tar.gz from Ralf CorsepiusJoel Sherrill10-1824/+14
<corsepiu@faw.uni-ulm.de> that migrates the SH port to multilib'ing. This patch involved moving a number of files in the CVS repository, adding new files, and deleting files from their previous location. Ralf gave good instructions (not repeated here) and here are his notes: Note 1: In this version, I did not change the installation points of the headers which are moved inside of the source-tree. This is a temporary hack for not breaking compatibility with 4.5 based BSPs, but will probably not last once having real multilibs (We would have include file conflicts when several BSPs/CPU_MODELS share a common installation prefix). Note 2: I hope not to have broken too much, but I would not be astonished if something goes wrong. Note 3: There are more patches to come :)
2000-06-14Moved PowerPC cache management code to libcpu. Also compiledJoel Sherrill2-302/+0
mpc8xx libcpu support for the first time and remove includes of bsp.h, references to BSP_Configuration, and Cpu_table. All of these can be obtained directly from RTEMS now.
2000-06-14Thread iterator and libgjc support submitted too early.Joel Sherrill5-215/+9
2000-06-13Added crude i960ka support.Joel Sherrill3-6/+38
2000-06-13Moved i386 and m68k cache management code to libcpu. EverythingJoel Sherrill2-306/+0
now is an implementation of the prototypes in rtems/rtems/cache.h. The libcpu/i386/wrapup directory is no longer needed. The PowerPC needs this done to it.

<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.

2000-02-29BSP now compiles and links with CAVSL board information. This includesJoel Sherrill1-3/+3
linkcmds updated, simio references removed, and switch to libchip for serial ports from simio. Added a MEMORY_MAP file to capture information about the various addresses on this board. In addition, many of the beta patches are now included.

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)

2000-01-31Patch rtems-rc-20000118-1.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill12-36/+0
that contains: * cleanups to configuration files * A reworked gccnewlib.spec.in: I have reformated it for enhanced readability and added more rtems-base packages. It now should be free of any installation conflicts (If there still remain some, they should be regarded as bugs). * A fix to the bin2boot RTEMS_BSP issue (make RTEMS_BSP="pc386 pc486" now works). * removes libbsp/bare/wrapup * Further cleanups

2000-01-21Patch from Eric Norum <eric@cls.usask.ca> to implement this:Joel Sherrill1-2/+3
I'd like to propose a change to RTEMS task variables that I think would make them more useful. I think that it is early enough in their existence to still make changes to their API. 1) Change type from `int' to `void *'. 2) Add extra argument to task_variable_add -- if non-NULL, a pointer to a `destructor' function to be called when the task exits. This function would be called with that task's value of the task variable as its argument. In many cases, the `dtor' function could be `free'. rtems_status_code rtems_task_variable_add ( rtems_id tid, void **ptr, void (*dtor)(void *)); rtems_status_code rtems_task_variable_delete (rtems_id tid, void **ptr); This would be all we'd need to cleanly and efficiently support C++ per-thread exception information without dragging in all that POSIX API stuff.
2000-01-14Removed warning.Joel Sherrill2-2/+4
2000-01-13POSIX message queues now include complete functionality includingJoel Sherrill5-89/+154
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 Sherrill7-63/+77
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.
