2009-01-31 Bart Veer <bartv@ecoscentric.com>
* cdl/hal_sparclite_sim.cdl: update compiler flags for gcc 4.x
2003-07-18 Nick Garnett <nickg@balti.calivar.com>
* cdl/hal_sparclite_sim.cdl:
Changed values for CYGNUM_HAL_RTC_NUMERATOR,
CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
"default_value" from "calculated". This makes it easier
to change these values globally.
2000-10-20 Jonathan Larmour <jlarmour@redhat.com>
* include/pkgconf/mlt_sparclite_sim_ram.mlt:
Add heap1 section
* include/pkgconf/mlt_sparclite_sim_ram.h:
* include/pkgconf/mlt_sparclite_sim_ram.ldi:
Regenerated
2000-02-10 Jesper Skov <jskov@redhat.com>
* cdl/hal_sparclite_sim.cdl: Added.
1999-11-25 Gary Thomas <gthomas@cygnus.co.uk>
* include/pkgconf/mlt_sparclite_sim_ram.h: New file.
1999-10-13 Hugo Tyson <hmt@cygnus.co.uk>
* include/pkgconf/hal_sparclite_sim.h: Add define of
CYGHWR_HAL_SPARCLITE_HAS_ASR17 for arch HAL to DTRT with SVT
(anticipating cores with no SVT at all, so no %asr17)
1999-04-08 John Dallaway <jld@cygnus.co.uk>
* include/pkgconf/*.ldi: Revised SECTION_* macro arguments to
avoid padded output sections (PR 19787)
1999-04-07 Hugo Tyson <hmt@cygnus.co.uk>
* src/hal_priv.c: Remove bogus FIX ME; it wasn't true.
1999-03-16 Hugo Tyson <hmt@cygnus.co.uk>
* include/halboot.si: Add a dummy LED macro for debug in the
vectors.S; correct a scary line length.
1999-03-04 Gary Thomas <gthomas@cygnus.co.uk>
* include/pkgconf/hal_sparclite_sim.h: Take out DEVICES dependencies.
1999-03-04 John Dallaway <jld@cygnus.co.uk>
* include/pkgconf/*.ldi: give all LDI files unique names so
that they can co-exist in an eCos build tree (PR 19184)
* include/pkgconf/*.mlt: give all MLT files unique names so
that they can co-exist in an eCos build tree (PR 19184)
1999-02-25 Hugo Tyson <hmt@cygnus.co.uk>
These log entries from 1999-02-22 to 1999-02-24 were executed in
a branch; this change is a merge of that branch into the trunk.
(1999-02-23 John Dallaway <jld@cygnus.co.uk>)
* include/pkgconf/hal_sparclite_sim.h: New rules
CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_GDB
CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_SERIAL_RS232_COMMON
(1999-02-22 Hugo Tyson <hmt@cygnus.co.uk>)
* src/hal_priv.c (hal_board_prestart, hal_board_poststart):
Shut down the erc32 watchdog in and enable interrupts in these two
new routines.
* include/halboot.si:
Remove N/A code that I was just storing here, and install the real
vector instructions in this fragment; there be cache-wangling to
do in hardware cases either side of the vector installation.
1999-02-20 Jonathan Larmour <jlarmour@cygnus.co.uk>
* include/hal_xpic.h:
Rename CYG_VECTOR_* -> CYGNUM_HAL_INTERRUPT_*
* src/hal_priv.c:
Add a FIX ME
1999-02-08 John Dallaway <jld@cygnus.co.uk>
* src/sim.ld: Remove platform-specific linker script for
MLT compliance.
* src/PKGconf.mak: Remove build rules for sim.ld.
* include/pkgconf/ram.*: Add MLT save file and and linker
script fragment for RAM startup.
1999-02-01 Hugo Tyson <hmt@cygnus.co.uk>
* include/halboot.si:
New file: performs platform-oriented setup of RAM and cache
controllers, and quietens any interrupt sources.
* include/pkgconf/hal_sparclite_sim.h:
Correct comments/CDL description of sim invocation.
1999-01-28 Hugo Tyson <hmt@cygnus.co.uk>
* include/hal_cache.h: NEW FILE to this directory; moved here from
the sparclite/arch tree; cache control is very much board-specific
* include/hal_clock.h: NEW FILE to this directory; it was a part
of hal_intr.h, but is now here because the clock is target determined.
* include/hal_xpic.h: NEW FILE to this directory; it was a part of
hal_intr.h, but is now here because the detail of interrupot
control is target determined.
* src/hal_priv.c: NEW FILE to this directory; it was a part
of hal_intr.h, but is now here because the clock is target
determined, and it's the clock that needs a local variable.
* src/PKGconf.mak (COMPILE): compile it.
1999-01-26 Hugo Tyson <hmt@cygnus.co.uk>
* src/sim.ld:
Add copyright notice. (Though these files will later be generated
by a tool and so not copyright, these default setups are.)
1999-01-22 Hugo Tyson <hmt@cygnus.co.uk>
* src/sim.ld:
Remove some bogus comments.
1999-01-21 Jonathan Larmour <jlarmour@cygnus.co.uk>
* src/sim.ld:
Remove all traces of non-CYG_KERNEL_USE_INIT_PRIORITY code
1999-01-21 Hugo Tyson <hmt@cygnus.co.uk>
* src/sim.ld:
Align bss and rom/ram_data starts and ends by 8 bytes to permit
fast copy routines.
1999-01-19 Hugo Tyson <hmt@cygnus.co.uk>
Modified files in arch:
* include/hal_arch.h
* include/hal_intr.h
* src/PKGconf.mak
* src/context.S
* src/hal_intr.c
* src/vec_ivsr.S
* src/vec_xvsr.S
* src/vectors.S
New files in arch:
* src/hal_boot.c (bss initialization, constructors &c)
* include/hal_cache.h (empty but required header)
Modified files in sim:
* include/hal_diag.h
Lots more progress; essentially, everything now works.
Simulator's treatment of stdio is poor though, it doesn't work
under pkgtest. This has been slowing me up.
1999-01-14 Hugo Tyson <hmt@cygnus.co.uk>
* ecc/ecc/hal/sparclite/...:
Initial checkin of SPARClite HAL; it doesn't work yet, except the
most trivial of tests - timer and interrupt manipulation stuff is
entirely absent.
Here's some documentation of the initial checkin tree; this will
change, as platform dependent stuff moves correctly into the sim
or <board> directories.
arch/current/include:
basetype.h nothing much here.
vectors.h definitions of symbols shared between the
various vector code assembler files, can be
included in both C and assembler.
hal_intr.h various macros for clock and interrupt
control plus the eCos vector numbering scheme; we
map thus:
what SPARC trap type eCos vector numbers
-----------------------------------------------
(not used) --- 0
interrupts (17-31) 1-15
user traps (128-255) 16
exceptions (1-9,36==4) 17-25
others (10,?) 26
-----------------------------------------------
Trap types 5 and 6 which would be eCos vectors 21
and 22 are handled in the trampoline code in
file src/vectors.S
hal_arch.h definition of a thread context, plus
macros for thread switching and the like. Some
ancillary bit twiddling macros and cache barriers
too.
arch/current/include/pkgconf:
hal_sparclite.h pkgconf config/header file.
arch/current/src:
vectors.S boot-up stuff, trampoline code that hangs
on the interrupt/trap vector, handlers for window
under/overflow. Saves some state in registers
then jumps to the interrupt or exception VSR
respectively.
Also instantiates the VSR table.
vec_ivsr.S the default interrupt VSR; it establishes
a C calling environment (ie. anticipates a window
overflow) then locks the scheduler, calls the ISR
with appropriate arguments, and then interrupt_end()
before undoing that environment, anticipating
window underflow and returning to the interrupted
instruction.
vec_xvsr.S the default exception AKA trap VSR; does
the same as the interrupt one but without the
scheduler lock or interrupt end.
hal_intr.c instantiates the ISR table used by the
code above.
context.S context switch code, saves and loads up a
whole register state, coroutine or longjump-like.
icontext.c initializes a context to "jump" to in
context.S at the birth of a new thread.
sim/current/include:
hal_diag.h macros to deal with debugging output via a
fake serial device of some kind; initially empty,
but definitely board/sim dependent.
sim/current/include/pkgconf:
hal_sparclite_sim.h pkgconf config/header file.
sim/current/src:
sim.ld linker script bits for "sim" target.
