4195 5685 d 22 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)		  
4152 5698 d 0 h jermar /trunk/kernel/arch/ia32/src/boot/ Fix typo.  
4151 5698 d 2 h decky /trunk/kernel/arch/ia32/src/ properly detect VESA 16 bpp modes with 5:5:5 colors  
4150 5698 d 3 h decky /trunk/kernel/arch/ia32/src/boot/ check for proper VESA mode attributes  
4149 5698 d 4 h decky /trunk/kernel/arch/ia32/src/boot/ ignore leading spaces in video mode command line  
4128 5703 d 4 h decky /trunk/kernel/arch/ia32/src/boot/ support for overriding the preconfigured VESA mode via GRUB command line option  
4127 5703 d 6 h decky /trunk/ parse VESA mode from a string
unify VESA initialization for ia32 and amd64		  
4015 5713 d 6 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)  
4014 5713 d 6 h decky /trunk/ cstyle  
4012 5713 d 20 h svoboda /trunk/ Task names should only contain base names of commands. Also add 'boot:' prefix for binaries loaded by the kernel.  
4011 5713 d 21 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3987 5714 d 22 h svoboda /trunk/kernel/ Read command line for multiboot modules on ia32 and copy it to task name. Other arches will need to initialize task names in the init structure to an empty string.  
3985 5714 d 23 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5714 d 23 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 5756 d 3 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3709 5789 d 23 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
2784 6061 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 6104 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)		  
2302 6382 d 1 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)		  
2222 6407 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
