3902 5648 d 5 h jermar /trunk/kernel/ Introduce a more platform-neutral name for programmed I/O.

The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers.
 
3790 5686 d 8 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 5690 d 6 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5698 d 9 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 5709 d 1 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3672 5720 d 0 h jermar /trunk/ Merge sparc branch to trunk.  
3234 5851 d 5 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5852 d 1 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3104 5902 d 13 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
2439 6273 d 23 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2218 6327 d 21 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 6390 d 23 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 6397 d 7 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6408 d 0 h jermar /trunk/ (c) versus (C)  
2065 6421 d 22 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2018 6445 d 3 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6447 d 0 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 6464 d 8 h decky /trunk/ make framebuffer code more generic  
1956 6490 d 9 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1837 6574 d 12 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.
