4676 5493 d 23 h jermar /trunk/ RGB conversion functions should work with a well-defined pixel format.  
4151 5629 d 1 h decky /trunk/kernel/arch/ia32/src/ properly detect VESA 16 bpp modes with 5:5:5 colors  
4148 5629 d 7 h decky /trunk/ as kernel little brother drivers are not needed anymore, the device numbers do not have to be correlated between kernel and uspace in any way
introduce new syscall sys_device_assign_devno() for generating system-wide unique device numbers for uspace
 
4096 5635 d 0 h decky /trunk/kernel/arch/ia32/src/drivers/ fix very strange condition  
3941 5654 d 21 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3930 5655 d 20 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3906 5659 d 19 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.
 
3902 5660 d 2 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 5698 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 5702 d 4 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5710 d 6 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 5720 d 23 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3672 5731 d 22 h jermar /trunk/ Merge sparc branch to trunk.  
3234 5863 d 3 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5863 d 22 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3104 5914 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
2439 6285 d 20 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2218 6339 d 18 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 6402 d 20 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 6409 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6419 d 21 h jermar /trunk/ (c) versus (C)  
2065 6433 d 20 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2018 6457 d 0 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2015 6458 d 21 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 6476 d 5 h decky /trunk/ make framebuffer code more generic  
1956 6502 d 7 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1837 6586 d 9 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.
 
1787 6609 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6617 d 1 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1754 6631 d 7 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1702 6638 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1667 6643 d 2 h jermar /kernel/trunk/ Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock.
 
1477 6650 d 13 h decky /kernel/trunk/arch/ cleanup  
1473 6650 d 22 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1371 6663 d 20 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer
 
1327 6668 d 3 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1318 6668 d 22 h vana /kernel/trunk/ Sysinfo userspace interface  
1313 6669 d 5 h jermar /kernel/trunk/ Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar().
 
1311 6670 d 3 h jermar /kernel/trunk/arch/ia32/src/drivers/ Fix number of frames allocated for VESA frame buffer in the singular
case when the frame buffer size is below FRAME_SIZE.
 
1310 6670 d 5 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.
