1905	6612 d 9 h	jermar	/trunk/kernel/arch/sparc64/src/	Small fixes. The sparc64 kernel now compiles again even if not compiled with SMP support.
1904	6613 d 3 h	jermar	/trunk/kernel/	IPI/cross-call support for sparc64. SMP on sparc64 is now fully supported.
1903	6613 d 23 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	6615 d 3 h	jermar	/trunk/kernel/arch/sparc64/include/	Implement spinlock and test_and_set for sparc64.
1901	6615 d 4 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	6615 d 5 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	6615 d 6 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	6615 d 22 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	6618 d 6 h	jermar	/trunk/	Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.
1896	6618 d 21 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	6620 d 22 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	6621 d 20 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	6622 d 8 h	jermar	/trunk/kernel/arch/sparc64/src/mm/	Small improvement in initialization of sparc64's TBSs.
1891	6622 d 21 h	jermar	/trunk/kernel/	sparc64 work: - Experimental support for TSB (Translation Storage Buffer).
1890	6623 d 7 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	6623 d 23 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
1888	6627 d 2 h	jermar	/trunk/	C99 compliant header guards (hopefully) everywhere in the kernel. Formatting and indentation changes. Small improvements in sparc64.
1887	6627 d 6 h	jermar	/trunk/kernel/arch/sparc64/	When creating TLB mapping for the sparc64 kernel, enable CV (cacheable virtually) bit. Also install locked mappings only in context 0.
1885	6627 d 10 h	jermar	/trunk/kernel/arch/sparc64/include/	On sparc64, get_stack_base() must use the unbiased %sp (i.e. %sp + 2047).
1884	6628 d 4 h	jermar	/trunk/kernel/arch/sparc64/src/	Unfortunatelly, the sparc64's FPRS register is writable by non-privileged software so we cannot save only half of the FPU context depending on FPRS dirty bits. Instead, we must save the entire FPU register file.
