Brings the behavour into line with OpenBoot. * corefile-n.h (core_map_write_N): Ditto * corefile.c (core_map_read_buffer): Ditto * corefile.c (core_map_write_buffer): Ditto * device_table.c (console_io_read_buffer_callback): Adjust to handle biased address. * device_table.c (console_io_write_buffer_callback): Ditto Wed Jan 17 18:36:09 1996 Andrew Cagney * device.c (attach_device_interrupt_edge): New. Interrupt model did not allow interrupts to be wired up as a general net (edges). Re-implement so that interrupt events can be passed to multiple controllers and interrupt controllers can further propogate interrupt events. * device.c (attach_device_interrupt_edge) : New, Ditto * device.c (detach_device_interrupt_edge) : New, Ditto * device.c (clean_device_interrupt_edges) : New, Ditto * device.c (device_interrupt_event) : New, Ditto * device.c (device_interrupt_attach) : New, Ditto * device.c (device_interrupt_detach) : New, Ditto * device.c (device_child_interrupt_attach) : New, Ditto * device.c (device_child_interrupt_detach) : New, Ditto * device.c (device_attach_interrupt) : Delete old * device.c (device_detach_interrupt) : Delete old * device.c (device_interrupt) : Delete old * device.c (device_interrupt_ack) : Delete old * device_table.c (unimp_*) : Update to match * device_table.c (icu_io_write_buffer_callback) : Update to use interface. * device_table.c (icu_interrupt_event_callback) : Ditto Wed Jan 17 18:18:40 1996 Andrew Cagney * device.c (external_to_device) : New function that provides a standard mapping between a devices internal representation (a pointer) and its external (or what is passed to a client) representation (a phandle). Implement using the cap object attached to the root node. * device.c (device_to_external) : Ditto * device.c (external_to_device_instance) : Ditto but for ihandle and device instance. * device.c (device_instance_to_external) : Ditto * Makefile (device.o): Add dependency on cap. * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code needing to translate between internal and external representations changed to use the external_to_device et.al. device operations. * emul_chirp.c (chirp_emul_*) : Ditto * Makefile (emul_chirp.o): Remove dependency on cap Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks on OpenBoot note section. Fri Jan 5 20:28:53 1996 Andrew Cagney * emul_generic.c (emul_write_buffer): Use vm faulting byte read/write calls for buffer transfers. This will cause a fault to occure if the transfer fails. CHRP catches the fault while the others suffer the consequences. (emul_read_buffer): Ditto. (emul_write_word): Ditto. (emul_read_word): Ditto. (emul_read_string): Ditto. Fri Jan 5 18:55:34 1996 Andrew Cagney * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call), emul_generic (emul_blr_instruction): Use a real blr instruction to return from a client service call. * emul_chirp.c (services): Add all OpenBoot services to table. * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c (emul_chirp_create) : Use names instead of numbers for instructions being stored in memory. Fri Jan 5 18:52:28 1996 Andrew Cagney * Makefile.in (maintainer-clean): Remove .log, core and *.core (From NetBSD) files. Wed May 29 22:57:40 1996 Andrew Cagney * ChangeLog.00, ChangeLog: ChangeLog from gdb-4.16 becomes ChangeLog.00
