168 * When performance monitoring is disabled, it is still possible to
169 determine the simulation speed by looking at the number of elapsed
170 ticks recorded by the event queue.
172 * psim.c (psim_write_register, psim_read_register): Force the cpu
173 to zero when it is either of `-1' or `nr_cpus'. In both cases the
174 next cpu would be zero any way.
176 * mon.c (mon_print_info): If possible, print the system cycle
177 performance. This is an indication of the number of instructions
180 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
182 * The code to allow an event queue to be updated during a signal
183 was missing. For main.c, a cntrl-c simulation termination wasn't
186 * The simulation would not correctly restart if an event requested
187 that the simulation be halted.

239 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
240 to be initialized independant of the rest of the simulation
241 initalization. Otherwize a trace option explictly set from gdb
242 could be overridden by hw_trace.
244 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
246 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
247 debug.c. It could be much simpler.
249 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

306 * The code that put values in and extracted values from the cache
307 was too compilicated. The cache table did not allow values to be
308 computed from cache entries. #defines could only be used when a
309 cache was present, remove the restriction.
311 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
312 scratch variable is defined when a cache entry is beinf
313 filled. Change the definition of a COMPUTE variable to be defined
314 when the cache entry is being used.
315 * gen-icache.c: Update.
317 * ld-cache.h, ld-cache.c: Change field names so that their meaning

333 * configure.in (enable-sim-icache): Clarify description. Make
334 #define one of the defaults regardless of the cache. Probably
335 should revamp and add a separate option.

2720 the devices currently available in the device table.
2721 * device_table.c: Add usage operator to each device.
2723 * corefile.c (core_create, core_device_create): Adjust so that the
2724 core device is created earlier for psim_tree(). Core can later be
2727 * psim.c (psim_create): Update to handle above way of creating
2728 things. Extract all information from the device tree.
2730 * device_tree.c (trace_*): New device node, its properties are
2731 used to set the value of the trace options. Init this device (in
2732 psim_options) when ever the options are updated.
2734 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
2736 * debug.h: Add trace_print_info, trace_print_device_tree and
2737 trace_dump_device_tree. The first is a replacement for the
2738 variable `print_info' found in main.c and sim_calls.c. The latter
2739 two enable the dumping of the entire device tree.
2741 * debug.c: Add to trace_description table.
2743 * main.c (main): Use above trace instead of local variable
2744 * sim_calls.c (sim_close): Ditto
2746 * device.c (device_tree_print_device): New. Prints the device
2747 tree in a format that is consistent with what can be parsed by the
2748 device tree load from file code.
2750 * psim.c (psim_create): Dump device tree if enabled. If nump
2751 selected, exit psim immediatly.
2753 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
2755 * corefile-n.h (core_map_read_N): When mapping from an address to
2756 a device, do not subtract the devices base. The device its self
2757 can do this. Brings the behavour into line with OpenBoot.
2758 * corefile-n.h (core_map_write_N): Ditto
2759 * corefile.c (core_map_read_buffer): Ditto
2760 * corefile.c (core_map_write_buffer): Ditto
2762 * device_table.c (console_io_read_buffer_callback): Adjust to
2763 handle biased address.
2764 * device_table.c (console_io_write_buffer_callback): Ditto
2766 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
2768 * device.c (attach_device_interrupt_edge): New. Interrupt model
2769 did not allow interrupts to be wired up as a general net (edges).
2770 Re-implement so that interrupt events can be passed to multiple
2771 controllers and interrupt controllers can further propogate
2774 * device.c (attach_device_interrupt_edge) : New, Ditto
2775 * device.c (detach_device_interrupt_edge) : New, Ditto
2776 * device.c (clean_device_interrupt_edges) : New, Ditto
2777 * device.c (device_interrupt_event) : New, Ditto
2778 * device.c (device_interrupt_attach) : New, Ditto
2779 * device.c (device_interrupt_detach) : New, Ditto
2780 * device.c (device_child_interrupt_attach) : New, Ditto
2781 * device.c (device_child_interrupt_detach) : New, Ditto
2783 * device.c (device_attach_interrupt) : Delete old
2784 * device.c (device_detach_interrupt) : Delete old
2785 * device.c (device_interrupt) : Delete old
2786 * device.c (device_interrupt_ack) : Delete old
2788 * device_table.c (unimp_*) : Update to match
2790 * device_table.c (icu_io_write_buffer_callback) : Update to use
2792 * device_table.c (icu_interrupt_event_callback) : Ditto
2794 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
2796 * device.c (external_to_device) : New function that provides a
2797 standard mapping between a devices internal representation (a
2798 pointer) and its external (or what is passed to a client)
2799 representation (a phandle). Implement using the cap object
2800 attached to the root node.
2802 * device.c (device_to_external) : Ditto
2803 * device.c (external_to_device_instance) : Ditto but for ihandle
2804 and device instance.
2805 * device.c (device_instance_to_external) : Ditto
2807 * Makefile (device.o): Add dependency on cap.
2809 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
2810 needing to translate between internal and external representations
2811 changed to use the external_to_device et.al. device operations.
2812 * emul_chirp.c (chirp_emul_*) : Ditto
2814 * Makefile (emul_chirp.o): Remove dependency on cap
2816 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
2818 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
2819 on OpenBoot note section.
2821 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
2823 * emul_generic.c (emul_write_buffer): Use vm faulting byte
2824 read/write calls for buffer transfers. This will cause a fault to
2825 occure if the transfer fails. CHRP catches the fault while the
2826 others suffer the consequences.
2827 (emul_read_buffer): Ditto.
2828 (emul_write_word): Ditto.
2829 (emul_read_word): Ditto.
2830 (emul_read_string): Ditto.
2832 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
2834 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
2835 emul_generic (emul_blr_instruction): Use a real blr instruction to
2836 return from a client service call.
2838 * emul_chirp.c (services): Add all OpenBoot services to table.
2840 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
2841 (emul_chirp_create) : Use names instead of numbers for
2842 instructions being stored in memory.
2844 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
2846 * Makefile.in (maintainer-clean): Remove .log, core and *.core
2847 (From NetBSD) files.
