3751 5676 d 17 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 5687 d 9 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5687 d 9 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3672 5698 d 8 h jermar /trunk/ Merge sparc branch to trunk.  
3631 5709 d 7 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 5759 d 7 h jermar /trunk/ Support for SYSENTER on ia32.  
3274 5815 d 13 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 5825 d 18 h decky / move unfinished ObjC support to a separate branch  
3234 5829 d 13 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5830 d 9 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3222 5848 d 12 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3209 5850 d 8 h jermar /trunk/kernel/arch/ia32/src/smp/ Allocate AP's GDT from first 4 GiB.  
3104 5880 d 21 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3097 5882 d 9 h decky /trunk/kernel/ resurrect klog  
3071 5883 d 13 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
3043 5884 d 8 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 5959 d 7 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 5963 d 19 h cejka /trunk/kernel/arch/ia32/src/ Added missing ia32/context.S from last commit.  
2725 6001 d 14 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 6002 d 12 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()
