  • shared/irq/i8259.c, shared/irq/irq.c: Code outside of cpukit should use the public API for rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the public API and directly accessing _CPU_ISR_Disable and _CPU_ISR_Enable, they were bypassing the compiler memory barrier directive which could lead to problems. This patch also changes the type of the variable passed into these routines and addresses minor style issues.

160

198
1992006-06-19      Till Straumann <strauman@slac.stanford.edu>
200
201        * shared/irq/irq_asm.S: Never allow the FPU to be switched on

229
230        * shared/irq/irq_init.c, shared/openpic/openpic.h
231        shared/openpic/openpic.c: The 8240's EPIC has a 'serial'
232        mode of operation for multiplexing 16 interrupt lines.
233        This introduces a pipeline delay which can cause
234        spurious interrupts unless ending the interrupt cycle
235        (EOI) is delayed accordingly.
236
2372005-12-01      Till Straumann <strauman@slac.stanford.edu>

241        prologue (some exceptions, e.g., altivec unavail.) are only
242        0x20 bytes apart. Also introduced a modified prologue
243        that switches r0..r3 shadowing off (r0..r3 undefined
244        on certain 603e variants when incurring a TLB miss).
245
2462005-11-29      Till Straumann <strauman@slac.stanford.edu>

278        supports high bats on 7450 CPUs; added argument checking to setdbat;
279        added getdbat; moved early initialization code (clear_bats) from BSP
280        to libcpu (CPU_clear_bats_early)

808        256 meg to allow operation on boards with larger RAM sizes.
809        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
810        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
811        function to allow operation on boards with CPUs other than the
812        MPC750.
813
8142001-05-14      Till Straumann <strauman@slac.stanford.edu>
815
816        * shared/bootloader/misc.c, shared/console/Makefile.am,
817        shared/console/console.c, shared/console/consoleIo.h,
818        shared/console/inch.c, shared/console/polled_io.c,
819        shared/console/uart.c, shared/console/uart.h, shared/include/bsp.h,
820        shared/irq/Makefile.am, shared/irq/irq.c, shared/irq/irq.h,
821        shared/irq/irq_init.c, shared/openpic/openpic.c,
822        shared/openpic/openpic.h, shared/pci/Makefile.am, shared/pci/pci.c,
823        shared/pci/pci.h, shared/residual/Makefile.am, shared/start/start.S,
824        shared/startup/bspstart.c, shared/vectors/vectors.S,
825        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
826        "libbsp/powerpc/shared" BSP has been modified considerably with the
827        goal to make it more flexible and reusable by other BSPs. The main
828        strategies were: - eliminate hardcoded base addresses; devices use
829        offsets and a BSP defined base address. - separate functionality
830        into different files (e.g. reboot from inch.c to reboot.c) which can
831        be overridden by a 'derived' BSP. - separate initialization code
832        into separate files (e.g.  PCI bridge detection/initialization was
833        separated from the more generic PCI access routines), also to make
834        it easier for 'derived' BSPs to substitute their own initialization
835        code. There are also a couple of enhancements and fixes: - IRQ
836        handling code now has a hook for attaching a VME bridge. - OpenPIC
837        is now explicitely initialized (polarities, senses). Eliminated the
838        implicit assumption on the presence of an ISA PIC. - UART and
839        console driver now supports more than 1 port. The current maximum of
840        2 can easily be extended by enlarging a table (it would even be
841        easier if the ISR API was not broken by design). - fixed polled_io.c
842        so it correctly supports console on COM2 - fixed TLB invalidation
843        code (start.S). - exception handler prints a stack backtrace. -
844        added BSP_pciFindDevice() to scan the pci bus for a particular
845        vendor/device/instance.

848
849        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
850        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
851        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
852        direction of segments to memory regions may also have been
853        addressed.  This was a sweep across all BSPs.
854
8552001-04-08      Joel Sherrill <joel@OARcorp.com>
856
857        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame
858
8592001-03-30      Eric Valette <valette@crf.canon.fr>
860
861        * shared/Makefile.am, shared/console/consoleIo.h,
862        shared/include/bsp.h: These modifications are part of the conversion
863        of the mpc8xx CPU to the "new exception processing model."
864        * configure.in, motorola_powerpc/Makefile.am,
865        motorola_powerpc/configure.in: These modifications are in support of
866        switching the mpc8xx to the use the "new exception processing
867        model."
868
8692000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
870
871        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
872
8732000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
874
875        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
876        $(RTEMS_TOPdir)/aclocal.
877
8782000-11-01      Joel Sherrill <joel@OARcorp.com>
879
880        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
881        and libcsupport.h moved from libc to lib/include/rtems and now must
882        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
883        while doing this.
884
8852000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
886
887        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
888        GNU canonicalization.
889
8902000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
891
892        * shared/startup/linkcmds: Added lines so DWARF debug information
893        would be available.  Otherwise gdb complains that the offsets for
894        the debug info are incorrect and doesn't load the files.
895
8962000-09-05      Joel Sherrill <joel@OARcorp.com>
897
898        * shared/start/start.S: Include proper files to compile.
