Rev	Age	Author	Path	Log message	Diff
4605	5615 d 10 h	decky	/branches/snapshot/	add task snapshoting branch
3672	5824 d 4 h	jermar	/trunk/	Merge sparc branch to trunk.
2071	6512 d 4 h	jermar	/trunk/	(c) versus (C)
2068	6519 d 11 h	jermar	/trunk/kernel/	Formatting and indentation fixes.
1903	6624 d 4 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.
1882	6638 d 11 h	jermar	/trunk/kernel/	Support for sparc64 FPU context.
1860	6651 d 5 h	jermar	/trunk/kernel/	A lot of untested sparc64 stuff: - Write ASID to hardware when a thread is about to run in userspace. - Add userspace() and switch_to_userspace() functions. - Handle special cases when the userspace spill/fill handler causes MMU trap. - Resolve some TODOs in the existing sparc64 code. - sparc64 has now C99 compliant header guards. - Formatting and indentation fixes.
1857	6652 d 8 h	jermar	/trunk/kernel/arch/sparc64/	sparc64 work. More bits needed to reach the userspace milestone were added. The preemptible_handler(), still a prototype, now contains all functionality it needs. Some sanitation was added to functions expecting page-aligned pointers to userspace window buffer.
1852	6656 d 5 h	jermar	/trunk/kernel/	sparc64 work. Bunch of changes in preparation for sparc64 mm and userspace support. Fix alignment of hardcoded_* variables in linker script.
1851	6661 d 10 h	jermar	/trunk/kernel/	sparc64 work. Define the istate structure. Move the identity-mapping handler to assembly. Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it. Little bit of formatting and indentation.
1789	6700 d 9 h	jermar	/trunk/	Fix ofw_memmap() in boot infrastructure. The cell size is 32-bit and not equal sizeof(ofw_arg_t). Define architecture dependant #address-cells and #size-cells for cases the respective properties are missing in the OpenFirmware device tree. The algorithm now works both for ppc32 and sparc64. Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure. Be more verbose during sparc64 boot. Move ALIGN_UP to generic part of boot/. Change header guards in several places so that they don't contain double underscore.
1787	6702 d 6 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1784	6703 d 3 h	jermar	/kernel/trunk/	Sync OpenFirmware functionality with boot. Random cleanup.
1780	6709 d 7 h	jermar	/kernel/trunk/	Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
1702	6730 d 10 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
664	6899 d 23 h	jermar	/kernel/trunk/	sparc64 work. Interrupt Levels 1 - 15 serviced. Minor changes in the exc_* functions.
658	6903 d 13 h	jermar	/kernel/trunk/arch/sparc64/include/	sparc64 work. Add functions to read and write TICK and TICK_compare registers. Add types describing TICK and TICK_compare registers.
650	6906 d 1 h	jermar	/kernel/trunk/	sparc64 work. Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions. Fix context save/restore to save/restore register %i7.
640	6908 d 1 h	jermar	/kernel/trunk/	sparc64 work. CPU identification.
