2784 5991 d 13 h jermar /trunk/kernel/arch/ Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem.		  
2783 5991 d 14 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2777 5996 d 0 h cejka /trunk/ Unified context handling code for amd64.  
2774 5996 d 1 h cejka /trunk/kernel/arch/ Context.s renamed to context.S for ia32 and fixed links for ia32xen.
Added asm macros for context save/restore and offset definitions.		  
2767 6000 d 15 h jermar /trunk/kernel/arch/amd64/src/ Fix breakage in non-debug amd64 build.  
2745 6012 d 23 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6033 d 20 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)		  
2723 6034 d 18 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2721 6034 d 20 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2713 6038 d 20 h decky /trunk/kernel/arch/amd64/src/boot/ remove fake tab  
2712 6038 d 20 h decky /trunk/kernel/ prettyprint output  
2703 6045 d 18 h jermar /trunk/kernel/arch/amd64/ Grow the initial identity mapping from 64M to 4G.
We should not allocate GDT's from above 4G or the amd64 will occassionally
triple-fault again.		  
2701 6045 d 22 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2697 6055 d 21 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2692 6059 d 17 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6105 d 12 h jermar /trunk/kernel/arch/ Formatting fixes.  
2612 6114 d 15 h jermar /trunk/kernel/arch/ Cleanup.  
2606 6115 d 18 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2604 6116 d 18 h jermar /trunk/kernel/arch/amd64/src/ Fix register names in exception dump and cstyle.  
2467 6271 d 17 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
