2307 6397 d 5 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2292 6405 d 17 h hudecek /branches/rcu/ updated to latest trunk revision, minor tweaks in tasklet.c  
2131 6440 d 9 h decky /branches/ add development branches  
2082 6501 d 13 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6506 d 6 h jermar /trunk/ (c) versus (C)  
2061 6524 d 13 h jermar /trunk/ Improve comments and fix formatting in (sparc64) TLS implementation.
Improve some comments and formatting in sparc64 uspace thread library
code.

Update required msim version.		  
2025 6543 d 3 h jermar /trunk/ Coding style fixes.  
2015 6545 d 6 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.		  
1890 6627 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.		  
1888 6631 d 9 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1868 6640 d 11 h jermar /trunk/ sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work		  
1866 6641 d 6 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.		  
1864 6642 d 3 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.		  
1863 6644 d 5 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.		  
1797 6691 d 2 h decky /trunk/uspace/ dummy Sparc64 uspace support (it just compiles)
