2071	6310 d 19 h	jermar	/trunk/	(c) versus (C)
2048	6342 d 20 h	jermar	/trunk/	Formatting and indentation changes.
2015	6349 d 19 h	jermar	/trunk/	Rework support for virtually indexed cache. Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to SYS_PHYSMEM_MAP syscall. Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP. Lots of coding style changes.
2010	6354 d 18 h	jermar	/trunk/kernel/arch/sparc64/src/mm/	Fix comment.
2009	6354 d 18 h	jermar	/trunk/kernel/	Initial support for handling illegal virtual aliases on sparc64.
1987	6368 d 20 h	jermar	/trunk/kernel/arch/sparc64/src/	Take the possible difference between kernel and physical address into account in TSB and userspace window buffer allocation and deallocation code.
1903	6422 d 19 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.
1892	6431 d 5 h	jermar	/trunk/kernel/arch/sparc64/src/mm/	Small improvement in initialization of sparc64's TBSs.
1891	6431 d 17 h	jermar	/trunk/kernel/	sparc64 work: - Experimental support for TSB (Translation Storage Buffer).
1890	6432 d 3 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.
1888	6435 d 22 h	jermar	/trunk/	C99 compliant header guards (hopefully) everywhere in the kernel. Formatting and indentation changes. Small improvements in sparc64.
1860	6449 d 20 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.
1787	6500 d 21 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1705	6528 d 4 h	cejka	/kernel/trunk/	Added file with modules definitions and descriptions. We are able to change modules order and their description in one place.
1702	6529 d 1 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
830	6652 d 1 h	jermar	/kernel/trunk/	Make ASID FIFO for mips32 be allocated statically. Make ASID FIFO for sparc64 and ia64 be allocated dynamically. Fix ia64 to call asid_fifo_init(). All three architectures now call asid_fifo_init() from as_arch_init().
756	6661 d 15 h	jermar	/kernel/trunk/	Memory management work. Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find(). Page table address is now extracted from the first (i.e. 'as') argument. Add a lot of infrastructure to make the above possible. sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
