4344 5677 d 9 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
4343 5677 d 9 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
4338 5677 d 10 h svoboda /branches/dynload/ Merge trunk changes up to r3787 to dynload.  
3674 5822 d 8 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3588 5844 d 17 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
2927 6026 d 20 h decky /branches/dynload/ added dynload branch  
2726 6122 d 20 h vana /trunk/ Basic IA64 boot and kernel suport for real machines  
2725 6125 d 16 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2071 6510 d 10 h jermar /trunk/ (c) versus (C)  
1888 6635 d 13 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6700 d 12 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6728 d 16 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
900 6833 d 12 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Proper TLB fault handlers' headers and prototypes.
PFN 0 needs no longer be marked unavailable to frame allocator.		  
823 6853 d 6 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
816 6853 d 16 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
815 6853 d 17 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
813 6854 d 6 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.		  
758 6860 d 7 h jermar /kernel/trunk/arch/ sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.		  
757 6860 d 9 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.		  
534 6919 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
