2787 5947 d 2 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2784 5954 d 21 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.
 
2725 5997 d 4 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)
 
2713 6002 d 4 h decky /trunk/kernel/arch/amd64/src/boot/ remove fake tab  
2703 6009 d 2 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.
 
2692 6023 d 1 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2302 6275 d 1 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2222 6300 d 22 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2219 6301 d 1 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2071 6381 d 22 h jermar /trunk/ (c) versus (C)  
1787 6572 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1641 6606 d 8 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1291 6639 d 4 h vana /kernel/trunk/arch/amd64/src/boot/ VESA detection failure fix on amd64  
1289 6639 d 5 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1063 6688 d 19 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1052 6689 d 2 h decky /kernel/trunk/arch/amd64/src/boot/ fix wrong structure members size assumption  
1039 6689 d 6 h decky /kernel/trunk/arch/ update for the use of more init tasks  
1037 6689 d 7 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
820 6724 d 20 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
 
807 6726 d 9 h palkovsky /kernel/trunk/arch/amd64/src/boot/ I'm unsure if simics is broken or the only one according to spec,
but SYSCALL now works even with simics.
 
798 6726 d 22 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
696 6755 d 23 h decky /kernel/trunk/arch/amd64/ AMD64 SMP boots again  
695 6756 d 0 h decky /kernel/trunk/arch/amd64/ make AMD64 boot again (using grub, see /boot tree), SMP is still broken  
694 6756 d 1 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
685 6756 d 3 h decky /kernel/trunk/arch/amd64/ AMD64 PM initialization  
680 6759 d 20 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64
 
534 6790 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6790 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6803 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
472 6816 d 4 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.
 
467 6817 d 2 h jermar /SPARTAN/trunk/arch/ Add sparc64 context_offset.h.
Fix symbolic links in amd64 to be relative.
 
457 6817 d 7 h decky /SPARTAN/trunk/ new build system almost finished  
417 6837 d 4 h palkovsky /SPARTAN/trunk/arch/amd64/src/boot/ Added identity mapping for more then 16MB - now it maps 64MB on boot.  
406 6843 d 21 h jermar /SPARTAN/trunk/arch/ Fix directives for K_TEXT_START, K_TEXT_START_2 and K_DATA_START sections to be more descriptive about section's content.
Remove LOAD(0xdeadbeaf) from ia32 linker script.
Remove __fake from amd64 pm.c.
 
347 6872 d 23 h jermar /SPARTAN/trunk/ Documentation updates for amd64, mips32 and ia32.

Replace %L with %P printf() formatter in MPS and ACPI detection functions to print addresses in maximal width.

Tweak memmap.S and IA-32 and AMd64 boot.S.
Cancel unneeded instructions.
Replace cmpl $0, %ebx with testl %ebx, %ebx.
Move memmap.S data to K_DATA_START section.
 
293 6881 d 19 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.

we are now ABI-correct and we do not #GP on va_arg to boot.

frames.
