4094 5602 d 4 h decky /trunk/kernel/genarch/ update for the new scheme of wiring device drivers to keyboard/serial modules  
4092 5602 d 4 h decky /trunk/kernel/genarch/ wire keyboard/serial module and device drivers in a more obvious way
(first a device driver is initialized and then it is connected to the generic module)
 
4078 5602 d 10 h decky /trunk/kernel/genarch/ add dummy serial line input and output drivers  
4043 5607 d 5 h jermar /trunk/ Serial line module.  
4042 5607 d 6 h jermar /trunk/ Complete emancipation of kernel serial controller drivers (i8042, ns16550 and
z8530). Provide a common keyboard module for PC and Sun keyboards. The serial
line module is still to follow.
 
4022 5611 d 1 h svoboda /trunk/ Move multiboot parsing to genarch/*/multiboot and adapt it for use with both ia32 and amd64. Multiboot info parsing now supported on amd64, too.  
4021 5611 d 2 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
3963 5620 d 6 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5620 d 7 h jermar /trunk/ Unbreak sparc64.
Due to the lack of userspace bus drivers for the z8530 and ns16550,
we are currently handling exactly one interrupt from these devices
in userspace.
 
3960 5621 d 0 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3941 5622 d 1 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5622 d 5 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3938 5622 d 6 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5622 d 22 h jermar /trunk/kernel/ Improve the ns16550 driver.

- The driver support multiple instances.
- It still remembers the last registered IRQ in a global structure (cannot be
easily fixed now)
- Was converted to use PIO directly
 
3932 5623 d 0 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3931 5623 d 0 h jermar /trunk/kernel/genarch/ Improve the i8042 kernel driver (phase I).

- Convert the code to be instance-aware
- Still using hardcoded initialization from legacy IO address
- Use elegant i8042 register map for PIO
 
3930 5623 d 0 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3927 5623 d 3 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3907 5626 d 12 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5626 d 23 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 5627 d 7 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.
 
3876 5630 d 2 h decky /trunk/kernel/genarch/ add BGR 888 visual, remove FB_INVERT_ENDIAN  
3779 5669 d 8 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3710 5688 d 1 h decky /trunk/ resurrect kernel logo  
3707 5688 d 3 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3704 5688 d 3 h decky /trunk/kernel/genarch/include/kbd/ add header  
3679 5697 d 22 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5699 d 2 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5705 d 2 h jermar /trunk/kernel/ Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself.
 
3646 5706 d 3 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5723 d 14 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3240 5826 d 12 h decky / move unfinished ObjC support to a separate branch  
3071 5884 d 7 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2510 6156 d 2 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2467 6240 d 4 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6245 d 7 h jermar /trunk/ Merge arm32 into trunk.  
2125 6362 d 2 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6370 d 9 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2093 6375 d 5 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6376 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
