2082 6319 d 13 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6323 d 5 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6324 d 5 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6324 d 6 h jermar /trunk/ (c) versus (C)  
2070 6324 d 13 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.		  
2069 6326 d 4 h jermar /trunk/ Improve formatting.  
2061 6342 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 6361 d 3 h jermar /trunk/ Coding style fixes.  
2015 6363 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.		  
2012 6366 d 4 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().		  
2006 6372 d 10 h decky /trunk/uspace/ start trivial file system driver  
2005 6372 d 11 h decky /trunk/ update rd  
1999 6374 d 15 h decky /trunk/ start RAM disk support  
1997 6378 d 7 h decky /trunk/ add version to init and boot loader  
1994 6380 d 13 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6380 d 14 h decky /trunk/ make framebuffer code more generic  
1992 6380 d 15 h decky /trunk/uspace/libc/include/ add bool.h  
1971 6403 d 4 h jermar /trunk/uspace/libc/generic/ Textual changes.  
1954 6407 d 5 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1942 6415 d 5 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1939 6415 d 9 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1938 6415 d 16 h decky /trunk/uspace/kbd/arch/mips32/src/ mips32: update kbd driver  
1931 6416 d 7 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1928 6416 d 11 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1923 6417 d 5 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.		  
1890 6445 d 14 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 6449 d 9 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1886 6449 d 13 h jermar /trunk/uspace/fb/ Mapping framebuffer as cacheable was identified to cause the sparc64 port not work on Sun Ultra 5.  
1880 6453 d 5 h jermar /trunk/ Small improvements here and there.  
1875 6456 d 6 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.		  
1874 6456 d 7 h jermar /trunk/uspace/kbd/ Cleanup and reorganize the kbd service a bit.  
1873 6456 d 7 h jermar /trunk/uspace/kbd/ sparc64 support for the kbd userspace service.  
1872 6457 d 4 h jermar /trunk/uspace/libc/generic/io/ read() and write() now check if the virtual function they want to
call exists. Thus, these calls will not kill the whole task
if called for instance from a driver task but gracefully fail.		  
1871 6457 d 17 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.		  
1869 6458 d 9 h jermar /trunk/ Pass "fb.bpp-align" property to userspace so that our fb task works properly even on
framebuffers used in some Sun hardware.		  
1868 6458 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		  
1867 6459 d 6 h jermar /trunk/uspace/ Prototype for mmap() should be in mman.h.
Anyway, is there any common sense behind naming of mman.h and mman.c?		  
1866 6459 d 6 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.		  
1864 6460 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 6462 d 5 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.
