From 21bfd93aaff71a70ca426adb5ccd8397e7d8e5ef Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 29 Sep 1998 12:40:33 +0000 Subject: Patch from Ralf Corsepius : Please find enclosed a patch which enables me to build the bare-bsp for sh-rtems. Changes: 1. Add preinstall to libbsp/bare/include/Makefile.in 2. Removed FORCEIT, add preinstall to libbsp/sh/gensh1/include/Makefile.in 3. Disabled support of set_vector from sh code (shared/setvec.c is still present but isn't used anymore), set_vector replaced with standard rtems functions. Problems still present: 1. Support of spin-delays in bare bsp 2. Proper support of cpu frequency To configure I used: /configure \ --target=sh-rtems \ --prefix=/sh-bare \ --enable-bare-cpu-model=sh7032 \ --enable-bare-cpu-cflags='-Wall -m1 -DMHZ=20 -DCPU_CONSOLE_DEVNAME="\"/dev/null\""' --enable-rtemsbsp=bare \ --disable-networking \ --disable-cxx \ --disable-posix \ --disable-tests IMO, if there are no objections to this patch, a similar approach should be applied to all CPUs/BSPs (esp. hppa1.1, mips64orion, ppc403, because they apply set_vector inside of libcpu). --- c/src/lib/libbsp/sh/gensh1/include/Makefile.in | 7 +++---- c/src/lib/libbsp/sh/gensh1/include/bsp.h | 8 +++++++- c/src/lib/libbsp/sh/gensh1/startup/Makefile.in | 2 +- c/src/lib/libbsp/sh/shared/setvec.c | 5 ++++- 4 files changed, 15 insertions(+), 7 deletions(-) (limited to 'c/src/lib/libbsp/sh') diff --git a/c/src/lib/libbsp/sh/gensh1/include/Makefile.in b/c/src/lib/libbsp/sh/gensh1/include/Makefile.in index 2a2cd51b24..e632fca2f1 100644 --- a/c/src/lib/libbsp/sh/gensh1/include/Makefile.in +++ b/c/src/lib/libbsp/sh/gensh1/include/Makefile.in @@ -30,8 +30,7 @@ include $(RTEMS_ROOT)/make/leaf.cfg CLEAN_ADDITIONS += CLOBBER_ADDITIONS += -all: $(SRCS) - $(INSTALL) -m 444 $(H_FILES) $(PROJECT_INCLUDE) - $(INSTALL) -m 444 $(EQ_FILES) $(PROJECT_INCLUDE) +all: preinstall -install: all +preinstall: $(SRCS) + @INSTALL@ $(INSTINCFLAGS) $(H_FILES) $(PROJECT_INCLUDE) diff --git a/c/src/lib/libbsp/sh/gensh1/include/bsp.h b/c/src/lib/libbsp/sh/gensh1/include/bsp.h index ea7c370d77..8f676d07fe 100644 --- a/c/src/lib/libbsp/sh/gensh1/include/bsp.h +++ b/c/src/lib/libbsp/sh/gensh1/include/bsp.h @@ -55,7 +55,11 @@ extern "C" { #define MUST_WAIT_FOR_INTERRUPT 0 -#define Install_tm27_vector( handler ) set_vector( (handler), 0, 1 ) +#define Install_tm27_vector( handler ) \ +{ \ + rtems_isr_entry ignored ; \ + rtems_interrupt_catch( (handler), 0, &ignored ) ; \ +} #define Cause_tm27_intr() @@ -110,12 +114,14 @@ extern void bsp_cleanup( void ); /* * FIXME: Should this go to libcpu/sh/sh7032 ? */ +#if 0 /* functions */ sh_isr_entry set_vector( /* returns old vector */ rtems_isr_entry handler, /* isr routine */ rtems_vector_number vector, /* vector number */ int type /* RTEMS or RAW intr */ ); +#endif #ifdef __cplusplus } diff --git a/c/src/lib/libbsp/sh/gensh1/startup/Makefile.in b/c/src/lib/libbsp/sh/gensh1/startup/Makefile.in index 52be4a84fb..08adccc862 100644 --- a/c/src/lib/libbsp/sh/gensh1/startup/Makefile.in +++ b/c/src/lib/libbsp/sh/gensh1/startup/Makefile.in @@ -11,7 +11,7 @@ PROJECT_ROOT = @PROJECT_ROOT@ PGM=${ARCH}/startup.rel # C source names, if any, go here -- minus the .c -C_PIECES=bsplibc bsppost bspstart bspclean sbrk setvec main +C_PIECES=bsplibc bsppost bspstart bspclean sbrk main C_FILES=$(C_PIECES:%=%.c) C_O_FILES=$(C_PIECES:%=${ARCH}/%.o) diff --git a/c/src/lib/libbsp/sh/shared/setvec.c b/c/src/lib/libbsp/sh/shared/setvec.c index 20bc080e23..e6c778b6a3 100644 --- a/c/src/lib/libbsp/sh/shared/setvec.c +++ b/c/src/lib/libbsp/sh/shared/setvec.c @@ -1,4 +1,8 @@ /* set_vector + * + * NOTE: This function is considered OBSOLETE and may vanish soon. + * Calls to set_vector should be replaced by calls to + * rtems_interrupt_catch or _CPU_ISR_install_raw_handler. * * This routine installs an interrupt vector on the target Board/CPU. * This routine is allowed to be as board dependent as necessary. @@ -52,4 +56,3 @@ sh_isr_entry set_vector( /* returns old vector */ return previous_isr; } - -- cgit v1.2.3
