{install\|remove}_io_interrupt_handler() now correctly handle the B_NO_ENABLE_COUNTER flag. Lots of cleanup: - moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's described in the BeBook (although it's probably not really used that often :)) - int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone); it's now entirely handled in the arch/x86/ section. - the io_vectors[] is now statically initialized, instead of allocated from the heap - removed {install\|remove}_interrupt_handler(); they weren't that useful, arch_smp_init() is now calling install_io_interrupt_handler() correctly instead - introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only (though on x86, it also has ARCH_INTERRUPT_BASE == 0x20). - changed the return type from {install\|remove}_io_interrupt_handler() from "long" to "status_t" - rearranged and cleaned the PIC initialization code, made the PIC code more prominent - changed comments that talk about a non existing 8239 (the PIC chip is actually 8259) - moved arch/x86/interrupts.h to the source directory, as it's not used outside - added BeOS compatible interrupts_enabled() function, that should replace our equivalent (and private) are_interrupts_enabled() git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12477 a95241bf-73f2-0310-859d-f6bbb57e9c96 2005-04-27 05:08:35 +04:00			`* Copyright 2002-2005, Axel Dörfler, axeld@pinc-software.de.

Some header cleanups. Renamed dbg_save_registers() to arch_...() since it's arch dependent. Removed unnecessary dependencies to stage2.h. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3138 a95241bf-73f2-0310-859d-f6bbb57e9c96 2003-05-03 18:12:16 +04:00			`#ifndef KERNEL_ARCH_INT_H`

Renamed some more init2 routines to init_post_vm() to make it clearer when and why they are called. Introduced a cpu_init_post_vm() that will now call arch_init_post_vm() instead of letting main() doing it. Fixed some return types (mostly from int to status_t). git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9438 a95241bf-73f2-0310-859d-f6bbb57e9c96 2004-10-21 05:41:29 +04:00			`status_t arch_int_init(kernel_args *args);`
			`status_t arch_int_init_post_vm(kernel_args *args);`
Added [arch_]int_post_device_manager() which is invoked after the device manager is initialized. For x86 it does nothing, but for PPC it searches for a supported interrupt controller and remembers it for later use. arch_int_{enable,disable}_io_interrupt() are implemented as well as handling of external exceptions (aka as I/O interrupts). We'll see later how well that works. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16271 a95241bf-73f2-0310-859d-f6bbb57e9c96 2006-02-07 05:50:32 +03:00			`status_t arch_int_init_post_device_manager(struct kernel_args *args);`

Renamed arch_int_is_interrupts_enabled() to arch_int_are_interrupts_enabled(). Replaced definitions for enable_interrupts() and are_interrupts_enabled() with static inlines.
