3751 5659 d 0 h svoboda /trunk/kernel/arch/ia32/src/drivers/ Revive kernel EGA fb driver. Plus fix bug -- was using memcpy() for scrolling instead of memmove().  
3709 5669 d 16 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5669 d 16 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3672 5680 d 16 h jermar /trunk/ Merge sparc branch to trunk.  
3631 5691 d 14 h jermar /trunk/kernel/arch/ia32/src/ The IA-32 manual is very secretive about the fact that the SYSENTER instruction
disables interrupts (I found only one evidence of this in the instruction's
pseudo code). The sysenter_handler needs to reenable the interrupts in order to
preserve the preemptive nature of the kernel.		  
3485 5741 d 14 h jermar /trunk/ Support for SYSENTER on ia32.  
3274 5797 d 20 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.		  
3240 5808 d 1 h decky / move unfinished ObjC support to a separate branch  
3234 5811 d 20 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5812 d 16 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3222 5830 d 19 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3209 5832 d 15 h jermar /trunk/kernel/arch/ia32/src/smp/ Allocate AP's GDT from first 4 GiB.  
3104 5863 d 4 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3097 5864 d 16 h decky /trunk/kernel/ resurrect klog  
3071 5865 d 21 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
3043 5866 d 15 h jermar /trunk/kernel/arch/ia32/ Some inline functions in memstr.h seem to be of uncertain origin (ia32).
Replace either with built-in functions or with generic functions.		  
2784 5941 d 14 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.		  
2775 5946 d 2 h cejka /trunk/kernel/arch/ia32/src/ Added missing ia32/context.S from last commit.  
2725 5983 d 21 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)		  
2723 5984 d 19 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()
