4344 5600 d 1 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
4343 5600 d 1 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
4338 5600 d 2 h svoboda /branches/dynload/ Merge trunk changes up to r3787 to dynload.  
3674 5745 d 0 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
3588 5767 d 10 h svoboda /branches/dynload/ Merge latest trunk changes into dynload.  
2927 5949 d 12 h decky /branches/dynload/ added dynload branch  
2726 6045 d 12 h vana /trunk/ Basic IA64 boot and kernel suport for real machines  
2725 6048 d 8 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 6433 d 2 h jermar /trunk/ (c) versus (C)  
1888 6558 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6623 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6651 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
900 6756 d 4 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 6775 d 23 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
816 6776 d 8 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
815 6776 d 9 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
813 6776 d 22 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 6782 d 23 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 6783 d 2 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 6842 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
