1890 6445 d 1 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 6448 d 19 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1886 6449 d 0 h jermar /trunk/uspace/fb/ Mapping framebuffer as cacheable was identified to cause the sparc64 port not work on Sun Ultra 5.  
1880 6452 d 15 h jermar /trunk/ Small improvements here and there.  
1875 6455 d 17 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 6455 d 17 h jermar /trunk/uspace/kbd/ Cleanup and reorganize the kbd service a bit.  
1873 6455 d 17 h jermar /trunk/uspace/kbd/ sparc64 support for the kbd userspace service.  
1872 6456 d 15 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 3 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.		  
1869 6457 d 20 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 6457 d 22 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 6458 d 16 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 6458 d 16 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.		  
1864 6459 d 13 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 6461 d 16 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.		  
1802 6508 d 12 h decky /trunk/ cleanup and unify the build system  
1801 6508 d 12 h decky /trunk/uspace/libc/arch/mips32eb/include/ sync mips32eb with mips32  
1798 6508 d 12 h decky /trunk/uspace/ make uspace compile for ppc64  
1797 6508 d 13 h decky /trunk/uspace/ dummy Sparc64 uspace support (it just compiles)  
1787 6513 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
