1923	6593 d 3 h	jermar	/trunk/	Replace the old IRQ dispatcher and IPC notifier with new implementation. Note that all architectures except for sparc64 are now broken and don't even compile.
1922	6594 d 11 h	jermar	/trunk/kernel/	More IRQ stuff. Modify the IRQ hash table functions to support lookup based on inr and devno. Add method member to irq_t.
1920	6595 d 12 h	jermar	/trunk/kernel/	Move the new IRQ redirector to ddi/. Add function for assigning unique device numbers. Change sparc64/drivers/kbd.c to assign devno to keyboard.
1919	6596 d 3 h	jermar	/trunk/kernel/	Prototypical implementation of new IRQ redirector in sparc64. The new code can support shared IRQs in kernel (and multiple IRQs per device). Userspace support is yet to be written. The only architecture that uses this code is actually sparc64 only.
1909	6607 d 3 h	jermar	/trunk/	Extend the OFW device tree node with a void pointer. The boot loader is supposed to reset all pointers in all nodes. The kernel uses the pointer to recognize that a particular device has already been visited and initialized. Read interrupt mapping from the OFW device tree for FHC devices (z8530) and EBUS devices (ns16550). In case of FHC devices, remove hardwired values from the code and use only values read from the tree. FHC initialization is started when a FHC device wants to map its interrupt. In case of EBUS devices, map the interrupt to INO. Interrupt enabling in the interrupt controller for that specific interrupt is not implemented yet.
1904	6611 d 8 h	jermar	/trunk/kernel/	IPI/cross-call support for sparc64. SMP on sparc64 is now fully supported.
1896	6617 d 2 h	jermar	/trunk/	Convert sparc64 to detect keyboard and determine its physical address by walking the memory representation of the OpenFirmware device tree. Add bus-specific functions that know how to apply the "ranges" property to one component of the "reg" property. Buses supported so far include FHC, EBUS and PCI.
1875	6632 d 4 h	jermar	/trunk/	sparc64 work. - Changes to enable userspace keyboard drivers. - Fix z8530 initialization (i.e. clear any pending Tx interrupts). - Experimental support for framebuffers with inverted colors.
1870	6634 d 3 h	jermar	/trunk/kernel/	Handle more sparc64 traps and improve handling of already handled traps.
1861	6638 d 10 h	jermar	/trunk/kernel/arch/sparc64/	Convert sparc64 traps using SIMPLE_HANDLER to using PREEMPTIBLE_HANDLER.
1849	6653 d 12 h	jermar	/trunk/kernel/	sparc64 work. interrupt_vector trap experimental handling. Minimal reverse-engineered FireHose Controller driver (documentation needed!). Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra is still polled.
1787	6690 d 5 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1780	6697 d 6 h	jermar	/kernel/trunk/	Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
1705	6717 d 12 h	cejka	/kernel/trunk/	Added file with modules definitions and descriptions. We are able to change modules order and their description in one place.
1703	6717 d 16 h	jermar	/kernel/trunk/arch/	Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.
1702	6718 d 9 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
1265	6761 d 10 h	jermar	/kernel/trunk/arch/	Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.
747	6856 d 1 h	jermar	/kernel/trunk/	ia64 work. Add nice wrappers for thash and ttag instructions. Add nice wrappers for accessing reion registers and PTA. Fix set_vhpt_environment(). Allocate and initialize page_ht (a.k.a. VHPT). Add missing header to sparc64. Remove excessive header from debug.h.
664	6887 d 23 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
