3802 5579 d 4 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
2784 5884 d 22 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 5927 d 5 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 6205 d 2 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2222 6230 d 23 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 6231 d 0 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6231 d 0 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 6301 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6311 d 23 h jermar /trunk/ (c) versus (C)  
1811 6489 d 7 h decky /trunk/kernel/arch/ unify bootstrapping  
1787 6502 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1641 6536 d 9 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1639 6536 d 17 h decky /kernel/trunk/arch/ia32/src/boot/ VESA VBE code cleanup, works in VMWare now  
1290 6569 d 5 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)
 
1288 6569 d 7 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 6569 d 9 h vana /kernel/trunk/ ia32 VESA FB support  
1037 6619 d 8 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
693 6686 d 2 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
680 6689 d 21 h decky /kernel/trunk/arch/ remove deprecated pre-grub stuff on ia32
prepare for the same on amd64
 
629 6710 d 0 h decky /kernel/trunk/ init task loading (yet buggy)
