 722
 723         * device_tree.c (trace_*): New device node, its properties are
 724         used to set the value of the trace options.  Init this device (in
 725         psim_options) when ever the options are updated.

 727 Wed Jan 17 19:46:07 1996  Andrew Cagney  <cagney@highland.com.au>
 728
 729         * debug.h: Add trace_print_info, trace_print_device_tree and
 730         trace_dump_device_tree.  The first is a replacement for the
 731         variable `print_info' found in main.c and sim_calls.c.  The latter
 732         two enable the dumping of the entire device tree.
 733
 734         * debug.c: Add to trace_description table.
 735
 736         * main.c (main): Use above trace instead of local variable
 737         * sim_calls.c (sim_close): Ditto
 738
 739         * device.c (device_tree_print_device): New.  Prints the device
 740         tree in a format that is consistent with what can be parsed by the
 741         device tree load from file code.
 742
 743         * psim.c (psim_create): Dump device tree if enabled. If nump
 744         selected, exit psim immediatly.
 745
 746 Wed Jan 17 19:36:52 1996  Andrew Cagney  <cagney@highland.com.au>
 747
 748         * corefile-n.h (core_map_read_N): When mapping from an address to
 749         a device, do not subtract the devices base.  The device its self
 750         can do this.  Brings the behavour into line with OpenBoot.
 751         * corefile-n.h (core_map_write_N): Ditto
 752         * corefile.c (core_map_read_buffer): Ditto
 753         * corefile.c (core_map_write_buffer): Ditto
 754
 755         * device_table.c (console_io_read_buffer_callback): Adjust to
 756         handle biased address.
 757         * device_table.c (console_io_write_buffer_callback): Ditto
 758
 759 Wed Jan 17 18:36:09 1996  Andrew Cagney  <cagney@highland.com.au>
 760
 761         * device.c (attach_device_interrupt_edge): New. Interrupt model
 762         did not allow interrupts to be wired up as a general net (edges).
 763         Re-implement so that interrupt events can be passed to multiple
 764         controllers and interrupt controllers can further propogate
 765         interrupt events.
 766
 767         * device.c (attach_device_interrupt_edge) : New, Ditto
 768         * device.c (detach_device_interrupt_edge) : New, Ditto

 773         * device.c (device_child_interrupt_attach) : New, Ditto
 774         * device.c (device_child_interrupt_detach) : New, Ditto
 775
 776         * device.c (device_attach_interrupt) : Delete old
 777         * device.c (device_detach_interrupt) : Delete old
 778         * device.c (device_interrupt) : Delete old

 780
 781         * device_table.c (unimp_*) : Update to match
 782
 783         * device_table.c (icu_io_write_buffer_callback) : Update to use
 784         interface.
 785         * device_table.c (icu_interrupt_event_callback) : Ditto
 786
 787 Wed Jan 17 18:18:40 1996  Andrew Cagney  <cagney@highland.com.au>
 788
 789         * device.c (external_to_device) : New function that provides a
 790         standard mapping between a devices internal representation (a
 791         pointer) and its external (or what is passed to a client)
 792         representation (a phandle).  Implement using the cap object
 793         attached to the root node.
 794
 795         * device.c (device_to_external) : Ditto
 796         * device.c (external_to_device_instance) : Ditto but for ihandle
 797         and device instance.
 798         * device.c (device_instance_to_external) : Ditto
 799
 800         * Makefile (device.o): Add dependency on cap.
 801
 802         * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
 803         needing to translate between internal and external representations
 804         changed to use the external_to_device et.al. device operations.
 805         * emul_chirp.c (chirp_emul_*) : Ditto
 806
 807         * Makefile (emul_chirp.o): Remove dependency on cap

 809 Sat Jan  6 10:13:26 1996  Andrew Cagney - aka Noid  <cagney@highland.com.au>
 810
 811         * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
 812         on OpenBoot note section.
 813
 814 Fri Jan  5 20:28:53 1996  Andrew Cagney  <cagney@hignland.com.au>
 815
 816         * emul_generic.c (emul_write_buffer): Use vm faulting byte
 817         read/write calls for buffer transfers.  This will cause a fault to
 818         occure if the transfer fails.  CHRP catches the fault while the
 819         others suffer the consequences.
 820         (emul_read_buffer): Ditto.
 821         (emul_write_word): Ditto.
 822         (emul_read_word): Ditto.
 823         (emul_read_string): Ditto.

 827         * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
 828         emul_generic (emul_blr_instruction): Use a real blr instruction to
 829         return from a client service call.
 830
 831         * emul_chirp.c (services): Add all OpenBoot services to table.
 832
 833         * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
 834         (emul_chirp_create) : Use names instead of numbers for
 835         instructions being stored in memory.
 836
 837 Fri Jan  5 18:52:28 1996  Andrew Cagney  <cagney@highland.com.au>
 838
 839         * Makefile.in (maintainer-clean): Remove .log, core and *.core
 840         (From NetBSD) files.
