| 729 | |
| 730 1998-09-12 Bart Veer <bartv@cygnus.co.uk> | |
| 731 | |
| 732 * include/pkgconf/hal_tx39.h: | |
| 733 Added missing descriptions (PR 17184) | |
| 734 | |
| 735 * src/vectors.S: | |
| 736 <pkgconf/kernel.h> was being included without properly checking | |
| 737 that the kernel package was enabled. | |
| 738 | |
| 739 * src/hal_misc.c (exception_handler): | |
| 740 Sort out exception handling options (PR 16953) | |
| 741 | |
| 742 1998-09-11 Nick Garnett <nickg@cygnus.co.uk> | |
| 743 PR 17230 | |
| 744 | |
| 745 * src/vectors.S (__default_interrupt_vsr): | |
| 746 Modified interrupt decode code to preserve raising interrupt | |
| 747 number to pass to ISR, even when using chained interrupts. | |
| 748 | |
| 749 1998-09-03 Bart Veer <bartv@cygnus.co.uk> | |
| 750 | |
| 751 * src/mips-stub.c: | |
| 752 Fixed type in config option name. | |
| 753 | |
| 754 1998-09-02 Bart Veer <bartv@cygnus.co.uk> | |
| 755 | |
| 756 * include/pkgconf/hal_tx39.h: | |
| 757 New header file for architecture-specific configuration options | |
| 758 | |
| 759 * tests/PKGconf.mak: | |
| 760 * src/PKGconf.mak: | |
| 761 Sort out package naming conventions. | |
| 762 | |
| 763 Tue Sep 1 19:26:45 1998 Hugo Tyson <hmt@cygnus.co.uk> | |
| 764 | |
| 765 * src/hal_misc.c: | |
| 766 Use CYGDBG_INFRA_DIAG_USE_DEVICE (from infra.h) instead of | |
| 767 CYG_DIAG_USE_DEVICE (badly named, from kernel.h). | |
| 768 | |
| 769 1998-09-01 Nick Garnett <nickg@cygnus.co.uk> | |
| 770 | |
| 771 * include/hal_intr.h: | |
| 772 Added CYG_EXCEPTION_COUNT. | |
| 773 | |
| 774 1998-08-28 Bart Veer <bartv@cygnus.co.uk> | |
| 775 | |
| 776 * src/vectors.S, src/context.S, src/hal_misc.c, src/mips-stub.c: | |
| 777 Updated for new kernel configuration option symbol names | |
| 778 | |
| 779 Fri Aug 28 10:01:24 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 780 | |
| 781 * src/hal_misc.c: | |
| 782 Rename __main() to cyg_hal_invoke_constructors() to prevent the | |
| 783 implied link with things called, or related to main(). Remove static | |
| 784 initialised variable as we can now guarantee it is only called | |
| 785 once. | |
| 786 | |
| 787 * src/vectors.S: | |
| 788 Instead of calling main(), call cyg_start() which lives in the infra | |
| 789 package. | |
| 790 Explicitly invoke constructors as it isn't done magically for us | |
| 791 any more, now that main() is no longer used. | |
| 792 | |
| 793 | |
| 794 1998-08-25 Nick Garnett <nickg@cygnus.co.uk> | |
| 795 | |
| 796 * src/vectors.S: | |
| 797 Now pass pointer to saved registers as third argument to | |
| 798 interrupt_end(). | |
| 799 | |
| 800 * include/hal_arch.h: | |
| 801 Added macros to support GDB. | |
| 802 | |
| 803 Tue Aug 25 02:33:59 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 804 | |
| 805 * include/mips_stub.h, src/hal_misc.c: | |
| 806 Add void to prototypes and typedefs that want it to silence warnings | |
| 807 | |
| 808 1998-08-21 Nick Garnett <nickg@cygnus.co.uk> | |
| 809 | |
| 810 * include/hal_cache.h: | |
| 811 Now includes cyg_type.h rather than ktypes.h. | |
| 812 | |
| 813 1998-08-18 Nick Garnett <nickg@cygnus.co.uk> | |
| 814 | |
| 815 * src/context.S: | |
| 816 * include/hal_arch.h: | |
| 817 * include/hal_io.h: | |
| 818 * include/hal_intr.h: | |
| 819 Now uses cyg_type.h rather than ktypes.h. | |
| 820 | |
| 821 * src/hal_misc.c: | |
| 822 * src/vectors.S: | |
| 823 Now uses hal.h rather than kernel.h. | |
| 824 | |
| 825 1998-07-23 Nick Garnett <nickg@cygnus.co.uk> | |
| 826 | |
| 827 * include/hal_intr.h: Fixed some issues raised bt code review. | |
| 828 | |
| 829 * src/context.S: | |
| 830 * include/hal_arch.h: Fixed some typos raised by code review. | |
| 831 | |
| 832 * include/hal_intr.h (HAL_INTERRUPT_MASK): | |
| 833 * src/vectors.S (hal_interrupt_level): Added hal_interrupt_level | |
| 834 to allow for interaction between HAL_INTERRUPT_UNMASK() and | |
| 835 HAL_INTERRUPT_SET_LEVEL(). | |
