4636 5470 d 22 h jermar /trunk/ sparc64's SP_DELTA needs more space.  
4556 5494 d 10 h decky /trunk/ define endianess externally to be able to exactly specify whether we are using UTF-32LE or UTF-32BE
quit messing with BOM in UTF-32
 
4468 5509 d 0 h decky /trunk/uspace/lib/libc/arch/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4234 5568 d 21 h svoboda /trunk/ Copy printf with Unicode support to userspace.  
4024 5600 d 20 h jermar /trunk/uspace/lib/libc/ PIO functions for uspace.  
3485 5749 d 21 h jermar /trunk/ Support for SYSENTER on ia32.  
3233 5820 d 4 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
2860 5922 d 23 h cejka /trunk/ Context handling unified for sparc64.  
2798 5934 d 22 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2610 6074 d 2 h jermar /trunk/ Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task).
 
2586 6090 d 20 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().
 
2541 6124 d 6 h jermar /trunk/uspace/ Header cleanup.
Move off_t, size_t and ssize_t into sys/types.h.
Get rid off the non-standard and dummy types.h.
 
2482 6215 d 18 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2479 6220 d 5 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2192 6298 d 4 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2141 6307 d 19 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
 
2082 6372 d 6 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6376 d 22 h jermar /trunk/ (c) versus (C)  
2061 6395 d 5 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 6413 d 20 h jermar /trunk/ Coding style fixes.  
2015 6415 d 22 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 6498 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.
 
1888 6502 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1868 6511 d 4 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 6511 d 22 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1864 6512 d 19 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 6514 d 22 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.
 
1797 6561 d 19 h decky /trunk/uspace/ dummy Sparc64 uspace support (it just compiles)
