4195 5709 d 3 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 5726 d 10 h decky /trunk/ parse VESA mode from a string
unify VESA initialization for ia32 and amd64
 
4015 5736 d 10 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 5738 d 4 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5738 d 4 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 5779 d 8 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
2784 6085 d 2 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 6127 d 9 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 6405 d 6 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2222 6431 d 3 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 6431 d 4 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6431 d 4 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 6501 d 10 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6512 d 3 h jermar /trunk/ (c) versus (C)  
1811 6689 d 11 h decky /trunk/kernel/arch/ unify bootstrapping  
1787 6702 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1641 6736 d 13 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1639 6736 d 21 h decky /kernel/trunk/arch/ia32/src/boot/ VESA VBE code cleanup, works in VMWare now  
1290 6769 d 9 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)
 
1288 6769 d 11 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.
