194 * When performance monitoring is disabled, it is still possible to
195 determine the simulation speed by looking at the number of elapsed
196 ticks recorded by the event queue.
198 * psim.c (psim_write_register, psim_read_register): Force the cpu
199 to zero when it is either of `-1' or `nr_cpus'. In both cases the
200 next cpu would be zero any way.
202 * mon.c (mon_print_info): If possible, print the system cycle
203 performance. This is an indication of the number of instructions
206 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
208 * The code to allow an event queue to be updated during a signal
209 was missing. For main.c, a cntrl-c simulation termination wasn't

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

332 * The code that put values in and extracted values from the cache
333 was too compilicated. The cache table did not allow values to be
334 computed from cache entries. #defines could only be used when a
335 cache was present, remove the restriction.
337 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
338 scratch variable is defined when a cache entry is beinf
339 filled. Change the definition of a COMPUTE variable to be defined
340 when the cache entry is being used.
341 * gen-icache.c: Update.
343 * ld-cache.h, ld-cache.c: Change field names so that their meaning

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

2719 * device.c (scan_*): Delete
2721 * device.c (device_tree_find_device): Rewrite to use above.
2722 * device.c (device_add_property): Ditto
2724 Wed Jan 17 19:51:56 1996 Andrew Cagney <cagney@highland.com.au>
2726 * psim.c(psim_options): Parse the psim options, installing their
2727 value in the device tree. Options are now first entered into a
2728 device tree and then extracted out again when needed. This allows
2729 greater flexability in configuration.
2731 * psim.c (psim_tree): Returns a basic device tree ready for
2732 parsing by psim_options.
2733 * psim.c (psim_usage): New. Give usage to varing levels of detail
2734 according to the verbosity. In turn output device and trace
2737 * main.c (main): Update to use new system
2738 * sim_calls.c (sim_open, sim_do_command): Ditto
2740 * psim.c (psim_options): Add `r' option - ram size.
2741 * psim.c (psim_options): Add `o' option - openboot tree entry.
2742 * psim.c (psim_options): Add `h'/`H' options - more help.
2744 * debug.c (trace_usage): Add more detailed help.
2745 * device.c (device_usage): New. Output help including a list of
2746 the devices currently available in the device table.
2747 * device_table.c: Add usage operator to each device.
2749 * corefile.c (core_create, core_device_create): Adjust so that the
2750 core device is created earlier for psim_tree(). Core can later be
2753 * psim.c (psim_create): Update to handle above way of creating
2754 things. Extract all information from the device tree.
2756 * device_tree.c (trace_*): New device node, its properties are
2757 used to set the value of the trace options. Init this device (in
2758 psim_options) when ever the options are updated.
2760 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
2762 * debug.h: Add trace_print_info, trace_print_device_tree and
2763 trace_dump_device_tree. The first is a replacement for the
2764 variable `print_info' found in main.c and sim_calls.c. The latter
2765 two enable the dumping of the entire device tree.
2767 * debug.c: Add to trace_description table.
2769 * main.c (main): Use above trace instead of local variable
2770 * sim_calls.c (sim_close): Ditto
2772 * device.c (device_tree_print_device): New. Prints the device
2773 tree in a format that is consistent with what can be parsed by the
2774 device tree load from file code.
2776 * psim.c (psim_create): Dump device tree if enabled. If nump
2777 selected, exit psim immediatly.
2779 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
2781 * corefile-n.h (core_map_read_N): When mapping from an address to
2782 a device, do not subtract the devices base. The device its self
2783 can do this. Brings the behavour into line with OpenBoot.
2784 * corefile-n.h (core_map_write_N): Ditto
2785 * corefile.c (core_map_read_buffer): Ditto
2786 * corefile.c (core_map_write_buffer): Ditto
2788 * device_table.c (console_io_read_buffer_callback): Adjust to
2789 handle biased address.
2790 * device_table.c (console_io_write_buffer_callback): Ditto
2792 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
2794 * device.c (attach_device_interrupt_edge): New. Interrupt model
2795 did not allow interrupts to be wired up as a general net (edges).
2796 Re-implement so that interrupt events can be passed to multiple
2797 controllers and interrupt controllers can further propogate
2800 * device.c (attach_device_interrupt_edge) : New, Ditto
2801 * device.c (detach_device_interrupt_edge) : New, Ditto

2818 * device_table.c (icu_interrupt_event_callback) : Ditto
2820 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
2822 * device.c (external_to_device) : New function that provides a
2823 standard mapping between a devices internal representation (a
2824 pointer) and its external (or what is passed to a client)
2825 representation (a phandle). Implement using the cap object
2826 attached to the root node.
2828 * device.c (device_to_external) : Ditto
2829 * device.c (external_to_device_instance) : Ditto but for ihandle
2830 and device instance.
2831 * device.c (device_instance_to_external) : Ditto
2833 * Makefile (device.o): Add dependency on cap.
2835 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
2836 needing to translate between internal and external representations
2837 changed to use the external_to_device et.al. device operations.
2838 * emul_chirp.c (chirp_emul_*) : Ditto
2840 * Makefile (emul_chirp.o): Remove dependency on cap
2842 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
2844 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
2845 on OpenBoot note section.
2847 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
2849 * emul_generic.c (emul_write_buffer): Use vm faulting byte
2850 read/write calls for buffer transfers. This will cause a fault to
2851 occure if the transfer fails. CHRP catches the fault while the
2852 others suffer the consequences.
2853 (emul_read_buffer): Ditto.
2854 (emul_write_word): Ditto.
2855 (emul_read_word): Ditto.
2856 (emul_read_string): Ditto.
