2000-08-02Patch from Eric Norum <eric@cls.usask.ca> to add optional support forJoel Sherrill1-3/+47
fast mutexes that bypass the API level to directly interface with the SuperCore.
2000-08-01Look at both hardware and software FP settings.Joel Sherrill1-2/+2
2000-08-01If the _VBR is set to 0xFFFFFFFF, then assume the vector jump table isJoel Sherrill1-1/+10
in ROM.
2000-08-01The fp_context field is needed if software or hardware floating pointJoel Sherrill1-1/+1
is available.
2000-08-01Patch from Eric Norum <eric@cls.usask.ca> to avoid lockup underJoel Sherrill1-9/+9
the correct circumstances of DMA buffer size, serial line interrupts, and ethernet interrupts the termios osend routine would lock up waiting for the raw output buffer semaphore.
2000-08-01Increased the defaults to be more reasonable.Joel Sherrill1-1/+3
2000-08-01Patch rtems-rc-20000801-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-2/+2
that switches the sparc from targopts.h to cpuopts.h.
2000-07-27Minor problems addressed with the merger and with the arm_bare_bsp.Joel Sherrill1-1/+1
That BSP now has a stub clock driver so the tests can link even if they won't execute. A handful of Makefiles had to be updated and we had to account for printk.c being a shared file now.
2000-07-27Port of RTEMS to the ARM processor family by Eric ValetteJoel Sherrill12-0/+1771
<valette@crf.canon.fr> and Emmanuel Raguet <raguet@crf.canon.fr> of Canon CRF - Communication Dept. This port includes a basic BSP that is sufficient to link hello world.
2000-07-26Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill11-7/+23
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.

2000-07-24Use bitwise and not cast to unsigned16 to remove upper bits.Joel Sherrill2-2/+6
2000-07-17Make _ISR_Dispatch global.Joel Sherrill1-0/+1
2000-07-17Update from Philip Quaife <rtemsdev@qs.co.nz> that was hand-merged.Joel Sherrill2-34/+75
This update addresses the following: + the ISR enable/disable/flash macros now work with old gcc versions. + the UI CCR bits are now masked since other example code did so + _ISR_Dispatch disables interrupts during call setup Together these removed the instabilities he was seeing.
2000-07-14Changed name of static table versions to avoid conflict.Joel Sherrill1-2/+2
2000-07-11Removed no cpu references.Joel Sherrill12-15/+15
2000-07-11Reworked score/cpu/sparc so it can be safely compiled multilib. AllJoel Sherrill10-127/+32
routines and structures that require CPU model specific information are now in libcpu. This primarily required moving erc32 specific information from score/cpu files to libcpu/sparc and the erc32 BSP.
2000-07-11Added Hitachi H8/300 to the list of CPUs that should be OK withJoel Sherrill1-0/+1
using cpuopts.h and not targopts.h.
2000-07-11Reworked score/cpu/i960 so it can be safely compiled multilib. AllJoel Sherrill5-533/+31
routines and structures that require CPU model specific information are now in libcpu. This required significant rework of the score/cpu header files and the creation of multiple header files and subdirectories in libcpu/i960.
2000-07-11Patch rtems-rc-20000711-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill8-9/+16
that decouples exec/ for the sh, m68k and i960 from targopts.h. NOTE: The change to system.h is a hack to enable cpuopts.h for some targets, but keep using targopts.h for others - I know it does *not* work for sparc, mips, i386 and ppc. This will have to be addressed as work continues on multilibing.
2000-07-10Patch rtems-rc-20000709-1.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-0/+6
that addresses aspects of the targopts.h multilib related issues. Changes: * Move targopts.h to libbsp/include, because the current targopts.h actually is a per-BSP-header and therefore can not stay below exec/. * Introduce an autoheader generated header file (exec/score/include/rtems/score/cpuopts.h), which shall take per-cpu configuration options only. * Move all autoconf-detectable/configure specified per-cpu option-defines from targopts.h to cpuopts.h. * Add Makefiles to the libbsp/shared directory hierarchy. Notes: * The new per-bsp targopts.h in libbsp includes the per-cpu cpuopts.h. This way, the new targopts.h is kept backward compatible to the old targopts.h and existing BSPs which (carelessly) include targopts.h (i386, ppc) should be kept working when using the multilib-disabled configuration scheme. * cpuopts.h is not yet complete, because the per-BSP make-targopts rules from custom/<BSP>.cfg files can not be applied to files below exec/ when building multilibs. * All files below exec/ should not include targopts.h anymore, but should include cpuopts.h instead. However, eliminating inclusion of targopts.h currently triggers further structural / header file inclusion related issues, because several ports apply BSP or CPU_MODEL specific defines from targopts.h below exec/
2000-07-07Moved old_exception_processing and new_exception_processing directoriesJoel Sherrill1-7/+1
from score/cpu to libcpu because the determination of which to use is based on RTEMS_CPU_MODEL. Thus it can not be determined based solely on multilib information.
2000-07-07Fixed problem reported by Victor V. Vengerov <Victor.Vengerov@oktet.ru>Joel Sherrill1-1/+7
where alarm() did not correctly account for the watchdog start_time and stop_time fields being based on ticks not seconds. This resulted in alarm() returning a bogus number of seconds remaining.
2000-07-07Moved __RTEMS_APPLICATION__ conditional to include the use of theJoel Sherrill1-1/+1
static inline routine _CORE_mutex_Seize_interrupt_trylock since static routines are not included when in an application.
2000-07-06Switched to faster implementation.Joel Sherrill1-25/+20
2000-07-06Patch from Eric Valette <valette@crf.canon.fr> and Yacine El KolliJoel Sherrill1-2/+2
<elkolli@crf.canon.fr> to add support for the mbx860_005b.
2000-07-06Added missing #endif's.Joel Sherrill2-3/+0
2000-07-06Corrected call to _CORE_mutex_Seize_interrupt_blocking.Joel Sherrill1-2/+5
2000-07-06Modfied to execute faster and have fewer instructions.Joel Sherrill1-38/+38
2000-07-06Switched to using isr disable version of _Objects_Get. When theJoel Sherrill1-13/+15
semaphore/mutex can be obtained immediately, this cuts execution time by 50%.
2000-07-06Added _Semaphore_Get_interrupt_disable.Joel Sherrill1-0/+10
2000-07-06Cleaned up to avoid disruptive use of inline conditionals.Joel Sherrill1-18/+16
2000-07-06Switched to using _POSIX_Mutex_Get_interrupt_disable to improve performance.Joel Sherrill1-3/+4
2000-07-06Added support for converting a mutex id to a pointer and returningJoel Sherrill1-21/+39
with interrupts disabled.
2000-07-06Reimplemented _Core_MUTEX_Seize to return with interrupts disabledJoel Sherrill2-7/+119
if the mutex is successfully obtained.
2000-07-06Added _CORE_semaphore_Seize_isr_disable.Joel Sherrill1-0/+56
2000-07-06Added _Objects_Get_isr_disable prototype and added numerous comments.Joel Sherrill1-7/+18
2000-07-06Removed unnecessary parentheses.Joel Sherrill1-4/+4
2000-07-06Added objjectgetbyisr.cJoel Sherrill1-2/+3
2000-07-06The code that attempts to obtain a mutex has now been inlined. TheJoel Sherrill1-83/+7
code remaining here now only blocks.
2000-07-06Directly index local table to avoid error check.Joel Sherrill3-12/+10
2000-07-06New file. Convert ID to pointer and return with interrupts -- notJoel Sherrill1-0/+83
dispatching -- disabled.
2000-07-06Format of return line changed.Joel Sherrill1-3/+3
2000-07-03Interrupt stack is allocated in _ISR_Handler_initialization notJoel Sherrill8-8/+8
_Interrupt_Manager_initialization.
2000-07-03Added blocked_count field to allow for optimizations.Joel Sherrill2-2/+4
2000-07-03Changed extra_system_initialization_stack to extra_mpci_receive_server_stackJoel Sherrill1-1/+1
to be consistent with other ports.
2000-07-02Fixed stat_ino should be st_ino.Joel Sherrill1-1/+1
2000-06-30Patch from Chris Johns <cjohns@cybertec.com.au> so the web serverJoel Sherrill2-3/+12
shuts down on error -- not exitting the system.
