1911	6615 d 4 h	jermar	/trunk/kernel/	Add support for interrupt mapping in the Sabre PCI controller. Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree. Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt. I suspect something needs to be enabled in the EBUS registers.
1910	6618 d 4 h	jermar	/trunk/kernel/	Rename INO to INR, for the sake of consistency with manuals.
1909	6619 d 5 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.
1906	6622 d 8 h	jermar	/trunk/	Small improvements in sparc64.
1905	6622 d 16 h	jermar	/trunk/kernel/arch/sparc64/src/	Small fixes. The sparc64 kernel now compiles again even if not compiled with SMP support.
1904	6623 d 11 h	jermar	/trunk/kernel/	IPI/cross-call support for sparc64. SMP on sparc64 is now fully supported.
1903	6624 d 6 h	jermar	/trunk/	SMP stuff for sparc64. Almost complete except for IPIs. The absence of IPI support deadlocks the kernel when more CPUs are configured.
1902	6625 d 10 h	jermar	/trunk/kernel/arch/sparc64/include/	Implement spinlock and test_and_set for sparc64.
1901	6625 d 11 h	jermar	/trunk/kernel/	Make SMP related parts of main.c more generic. Move initialization of local APIC to architecture specific code. Add arch_post_cpu_init() to support the above.
1900	6625 d 13 h	jermar	/trunk/kernel/arch/sparc64/src/	Block the secondary processors after they setup kernel mapping in ITLB and DTLB and switch to kernel trap table.
1899	6625 d 13 h	jermar	/trunk/	sparc64 work: - Loader now starts all processors. - Kernel halts all but the bootstrup processor for now. - Read clock-frequency from the respective processor node in the device tree
1898	6626 d 6 h	jermar	/trunk/kernel/	Support for FFB (Creator 3D) framebuffer detection on sparc64. (Not tested as the Ultra 60, which I have for testing, and which only has this type of framebuffer doesn't boot for some unknown reason.)
1897	6628 d 13 h	jermar	/trunk/	Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.
1896	6629 d 5 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.
1895	6631 d 6 h	jermar	/trunk/	More ofw_tree work and fixes. Add ofw_tree_lookup(). Every ofw_tree_node now also contains a disambigued name which is essential for tree lookups.
1894	6632 d 4 h	jermar	/trunk/	Add balloc() (a.k.a boot allocator): - balloc() only needs to know how to allocate memory. - Memory allocated via balloc() is supposed to be passed to kernel and never freed by boot itself. - make kernel aware of boot allocations More work on OFW device tree: - use balloc() to efficiently and safely allocate memory for the canonical copy of the device tree sparc64 boot: - pass OFW device tree root node pointer to kernel
1892	6632 d 16 h	jermar	/trunk/kernel/arch/sparc64/src/mm/	Small improvement in initialization of sparc64's TBSs.
1891	6633 d 4 h	jermar	/trunk/kernel/	sparc64 work: - Experimental support for TSB (Translation Storage Buffer).
1890	6633 d 15 h	jermar	/trunk/	- Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for them. - Slightly fix and improve both the kernel and userspace atomic_add() on sparc64. - More TSB work on the sparc64 front.
1889	6634 d 6 h	jermar	/trunk/kernel/	Fix bug in mm/as.c: - as_area_destroy() should not work with AS but as sparc64 work: - start implementing TSB support
