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

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

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

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

2721 * sim_calls.c (sim_open, sim_do_command): Ditto
2723 * psim.c (psim_options): Add `r' option - ram size.
2724 * psim.c (psim_options): Add `o' option - openboot tree entry.
2725 * psim.c (psim_options): Add `h'/`H' options - more help.
2727 * debug.c (trace_usage): Add more detailed help.
2728 * device.c (device_usage): New. Output help including a list of
2729 the devices currently available in the device table.
2730 * device_table.c: Add usage operator to each device.
2732 * corefile.c (core_create, core_device_create): Adjust so that the
2733 core device is created earlier for psim_tree(). Core can later be
2736 * psim.c (psim_create): Update to handle above way of creating
2737 things. Extract all information from the device tree.
2739 * device_tree.c (trace_*): New device node, its properties are
2740 used to set the value of the trace options. Init this device (in
2741 psim_options) when ever the options are updated.
2743 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
2745 * debug.h: Add trace_print_info, trace_print_device_tree and
2746 trace_dump_device_tree. The first is a replacement for the
2747 variable `print_info' found in main.c and sim_calls.c. The latter
2748 two enable the dumping of the entire device tree.
2750 * debug.c: Add to trace_description table.
2752 * main.c (main): Use above trace instead of local variable
2753 * sim_calls.c (sim_close): Ditto
2755 * device.c (device_tree_print_device): New. Prints the device
2756 tree in a format that is consistent with what can be parsed by the
2757 device tree load from file code.
2759 * psim.c (psim_create): Dump device tree if enabled. If nump
2760 selected, exit psim immediatly.
2762 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
2764 * corefile-n.h (core_map_read_N): When mapping from an address to
2765 a device, do not subtract the devices base. The device its self
2766 can do this. Brings the behavour into line with OpenBoot.
2767 * corefile-n.h (core_map_write_N): Ditto
2768 * corefile.c (core_map_read_buffer): Ditto
2769 * corefile.c (core_map_write_buffer): Ditto
2771 * device_table.c (console_io_read_buffer_callback): Adjust to
2772 handle biased address.
2773 * device_table.c (console_io_write_buffer_callback): Ditto
2775 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
2777 * device.c (attach_device_interrupt_edge): New. Interrupt model
2778 did not allow interrupts to be wired up as a general net (edges).
2779 Re-implement so that interrupt events can be passed to multiple
2780 controllers and interrupt controllers can further propogate
2783 * device.c (attach_device_interrupt_edge) : New, Ditto
2784 * device.c (detach_device_interrupt_edge) : New, Ditto
2785 * device.c (clean_device_interrupt_edges) : New, Ditto
2786 * device.c (device_interrupt_event) : New, Ditto
2787 * device.c (device_interrupt_attach) : New, Ditto
2788 * device.c (device_interrupt_detach) : New, Ditto
2789 * device.c (device_child_interrupt_attach) : New, Ditto
2790 * device.c (device_child_interrupt_detach) : New, Ditto
2792 * device.c (device_attach_interrupt) : Delete old
2793 * device.c (device_detach_interrupt) : Delete old
2794 * device.c (device_interrupt) : Delete old
2795 * device.c (device_interrupt_ack) : Delete old
2797 * device_table.c (unimp_*) : Update to match
2799 * device_table.c (icu_io_write_buffer_callback) : Update to use
2801 * device_table.c (icu_interrupt_event_callback) : Ditto
2803 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
2805 * device.c (external_to_device) : New function that provides a
2806 standard mapping between a devices internal representation (a
2807 pointer) and its external (or what is passed to a client)
2808 representation (a phandle). Implement using the cap object
2809 attached to the root node.
2811 * device.c (device_to_external) : Ditto
2812 * device.c (external_to_device_instance) : Ditto but for ihandle
2813 and device instance.
2814 * device.c (device_instance_to_external) : Ditto
2816 * Makefile (device.o): Add dependency on cap.
2818 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
2819 needing to translate between internal and external representations
2820 changed to use the external_to_device et.al. device operations.
2821 * emul_chirp.c (chirp_emul_*) : Ditto
2823 * Makefile (emul_chirp.o): Remove dependency on cap
2825 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
2827 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
2828 on OpenBoot note section.
2830 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
2832 * emul_generic.c (emul_write_buffer): Use vm faulting byte
2833 read/write calls for buffer transfers. This will cause a fault to
2834 occure if the transfer fails. CHRP catches the fault while the
2835 others suffer the consequences.
2836 (emul_read_buffer): Ditto.
2837 (emul_write_word): Ditto.
2838 (emul_read_word): Ditto.
2839 (emul_read_string): Ditto.
2841 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
2843 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
2844 emul_generic (emul_blr_instruction): Use a real blr instruction to
2845 return from a client service call.
2847 * emul_chirp.c (services): Add all OpenBoot services to table.
2849 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
2850 (emul_chirp_create) : Use names instead of numbers for
2851 instructions being stored in memory.
2853 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
2855 * Makefile.in (maintainer-clean): Remove .log, core and *.core
