4605 5683 d 23 h decky /branches/snapshot/ add task snapshoting branch  
4195 5777 d 17 h decky /trunk/kernel/arch/ detect SYSENTER/SYSEXIT support on boot
(this serves as a hint for people who try to boot HelenOS on Bochs emulating plain Pentium,
unfortunatelly it also kills VirtualBox, as it does not support SYSENTER/SYSEXIT officially,
see http://www.virtualbox.org/ticket/1248)
 
4127 5795 d 0 h decky /trunk/ parse VESA mode from a string
unify VESA initialization for ia32 and amd64
 
4015 5805 d 0 h decky /trunk/kernel/arch/ia32/ rename ia32_cboot() to arch_pre_main() and move it to ia32.c (to be in line with other platforms)  
3985 5806 d 17 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5806 d 18 h svoboda /trunk/kernel/ The ia32-specific boot code is written completely in assembly for no reason. Start fixing this. For now rewrite the copying of multiboot info to C.  
3802 5847 d 21 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
2784 6153 d 16 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 6195 d 23 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)
 
2302 6473 d 19 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2222 6499 d 16 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2221 6499 d 18 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6499 d 18 h decky /trunk/kernel/arch/ia32/src/boot/ check for PSE support, add error message on PSE not present
make initial mapping explicitly writeable, turn PAE explicitly off (just in case)
 
2089 6570 d 0 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6580 d 16 h jermar /trunk/ (c) versus (C)  
1811 6758 d 1 h decky /trunk/kernel/arch/ unify bootstrapping  
1787 6770 d 19 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1641 6805 d 3 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1639 6805 d 11 h decky /kernel/trunk/arch/ia32/src/boot/ VESA VBE code cleanup, works in VMWare now  
1290 6837 d 23 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)
 
1288 6838 d 1 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1287 6838 d 3 h vana /kernel/trunk/ ia32 VESA FB support  
1037 6888 d 1 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
693 6954 d 19 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
680 6958 d 14 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64
 
629 6978 d 17 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6978 d 19 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
534 6989 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6989 d 18 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
506 7001 d 18 h decky /kernel/trunk/ preparation for init task loading  
501 7001 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
472 7014 d 23 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.
 
451 7016 d 18 h decky /SPARTAN/trunk/arch/ia32/src/boot/ (ignore this :))  
450 7016 d 18 h decky /SPARTAN/trunk/arch/ia32/src/boot/ (ignore this :))  
406 7042 d 16 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.
 
371 7063 d 14 h jermar /SPARTAN/trunk/arch/ia32/src/ Complete map_kernel() in boot.S to map the entire 4G space.

Change IA-32 frame_arch_init() to add zone with lower base addresses first.
 
347 7071 d 17 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.
 
323 7076 d 1 h jermar /SPARTAN/trunk/ Add comments for new floating point modifiers to print.c.
Remove left-over comments from AMD64 and IA-32 page.c.
Coding style clean up.
 
314 7078 d 14 h palkovsky /SPARTAN/trunk/ Small cleanups  
300 7080 d 0 h palkovsky /SPARTAN/trunk/arch/ia32/ Backported AMD64 linker and boot changes back to IA32.
