1880 6634 d 3 h jermar /trunk/ Small improvements here and there.  
1879 6635 d 11 h jermar /trunk/kernel/arch/sparc64/src/ Revert last change.
The register window save area is automatically allocated by the SAVE instruction.		  
1878 6635 d 13 h jermar /trunk/kernel/arch/sparc64/src/ Even the first kernel register window after the switch from userspace stack needs
proper register window save area [sparc64].		  
1877 6635 d 14 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1876 6635 d 14 h jermar /trunk/kernel/arch/sparc64/src/trap/ Fixes for sparc64's preemptible_handler().
Resynchronize CWP with that of TL=0.		  
1875 6637 d 4 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 6637 d 4 h jermar /trunk/uspace/kbd/ Cleanup and reorganize the kbd service a bit.  
1873 6637 d 4 h jermar /trunk/uspace/kbd/ sparc64 support for the kbd userspace service.  
1872 6638 d 2 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 6638 d 15 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.		  
1870 6639 d 3 h jermar /trunk/kernel/ Handle more sparc64 traps and improve handling of already handled traps.  
1869 6639 d 7 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 6639 d 9 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 6640 d 3 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 6640 d 4 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.		  
1865 6640 d 5 h jermar /trunk/kernel/ sparc64 kernel fixes  
1864 6641 d 0 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 6643 d 3 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.		  
1862 6643 d 7 h jermar /trunk/kernel/ sparc64 work.
Kernel syscall support.
Modify the preemptive_handler for the use by syscalls.		  
1861 6643 d 10 h jermar /trunk/kernel/arch/sparc64/ Convert sparc64 traps using SIMPLE_HANDLER to using PREEMPTIBLE_HANDLER.
