3888 5613 d 4 h jermar /tags/0.4.0/ Tag 0.4.0.  
3790 5650 d 6 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3779 5654 d 4 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5662 d 7 h svoboda /trunk/kernel/arch/ia32/src/drivers/ Revive kernel EGA fb driver. Plus fix bug -- was using memcpy() for scrolling instead of memmove().  
3707 5672 d 23 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3672 5683 d 22 h jermar /trunk/ Merge sparc branch to trunk.  
3234 5815 d 3 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5815 d 23 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3104 5866 d 11 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
2439 6237 d 21 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2218 6291 d 19 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)		  
2107 6354 d 21 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2089 6361 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6371 d 22 h jermar /trunk/ (c) versus (C)  
2065 6385 d 20 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2018 6409 d 1 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6410 d 22 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.		  
1993 6428 d 6 h decky /trunk/ make framebuffer code more generic  
1956 6454 d 7 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1837 6538 d 10 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
