4063 5557 d 3 h rimsky /branches/sparc/uspace/lib/libc/arch/sparc64/include/ Fixed the bug which caused unexpected MMU misses. The fix breaks sun4u ports - this will be solved once the sun4v is integrated with the new configuration mechanism, which allows to define common options for both kernel and uspace.  
3492 5702 d 6 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3343 5758 d 8 h decky /branches/sparc/ add sparc branch  
3233 5781 d 10 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
2860 5884 d 5 h cejka /trunk/ Context handling unified for sparc64.  
2798 5896 d 4 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2610 6035 d 9 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 6052 d 2 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().
 
2541 6085 d 13 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 6177 d 0 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2479 6181 d 12 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2192 6259 d 11 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2141 6269 d 2 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 6333 d 12 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6338 d 5 h jermar /trunk/ (c) versus (C)  
2061 6356 d 12 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 6375 d 2 h jermar /trunk/ Coding style fixes.  
2015 6377 d 5 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 6459 d 13 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 6463 d 8 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
