1883	6641 d 6 h	jermar	/trunk/kernel/arch/sparc64/	More sparc64 FPU trap handlers.
1882	6641 d 6 h	jermar	/trunk/kernel/	Support for sparc64 FPU context.
1881	6642 d 7 h	jermar	/trunk/	sparc64 work: - find a CPU node and read its clock_frequency attribute - implement asm_delay_loop() - set TICK_COMPARE register according to processor frequency - small improvements at random places OpenFirmware work: - two new functions for walking the device tree Generic boot loader work: - added basic string functions Usual pile of indentation and formatting fixes.
1880	6643 d 22 h	jermar	/trunk/	Small improvements here and there.
1879	6645 d 7 h	jermar	/trunk/kernel/arch/sparc64/src/	Revert last change. The register window save area is automatically allocated by the SAVE instruction.
1878	6645 d 9 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	6645 d 10 h	jermar	/trunk/kernel/	Coding style fixes. Remove unneeded sparc64 dummy functions.
1876	6645 d 10 h	jermar	/trunk/kernel/arch/sparc64/src/trap/	Fixes for sparc64's preemptible_handler(). Resynchronize CWP with that of TL=0.
1875	6647 d 0 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	6647 d 0 h	jermar	/trunk/uspace/kbd/	Cleanup and reorganize the kbd service a bit.
1873	6647 d 0 h	jermar	/trunk/uspace/kbd/	sparc64 support for the kbd userspace service.
1872	6647 d 22 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	6648 d 10 h	jermar	/trunk/	Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN. Omit tests for architecture endianness in deciding framebuffer endianness.
1870	6648 d 23 h	jermar	/trunk/kernel/	Handle more sparc64 traps and improve handling of already handled traps.
1869	6649 d 3 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	6649 d 5 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	6649 d 23 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	6649 d 23 h	jermar	/trunk/uspace/	Indentation and formatting facelift for libc. Libc headers now have C99 compliant guards.
1865	6650 d 1 h	jermar	/trunk/kernel/	sparc64 kernel fixes
1864	6650 d 20 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.
