3934 5658 d 6 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 5658 d 7 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3931 5658 d 8 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 5658 d 8 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3927 5658 d 10 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3907 5661 d 19 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5662 d 7 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 5662 d 14 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 5665 d 10 h decky /trunk/kernel/genarch/ add BGR 888 visual, remove FB_INVERT_ENDIAN  
3779 5704 d 16 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3710 5723 d 8 h decky /trunk/ resurrect kernel logo  
3707 5723 d 11 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3704 5723 d 11 h decky /trunk/kernel/genarch/include/kbd/ add header  
3679 5733 d 5 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5734 d 10 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5740 d 9 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 5741 d 10 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5758 d 22 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3240 5861 d 19 h decky / move unfinished ObjC support to a separate branch  
3071 5919 d 15 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2510 6191 d 10 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 6275 d 12 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6280 d 15 h jermar /trunk/ Merge arm32 into trunk.  
2125 6397 d 10 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6405 d 16 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 6410 d 13 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6411 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2085 6417 d 15 h decky /trunk/kernel/ typedef elimination  
2071 6422 d 9 h jermar /trunk/ (c) versus (C)  
1994 6478 d 16 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6478 d 17 h decky /trunk/ make framebuffer code more generic  
1957 6504 d 17 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6504 d 19 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1921 6517 d 10 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6517 d 18 h jermar /trunk/kernel/ Move the new IRQ redirector to ddi/.
Add function for assigning unique device numbers.
Change sparc64/drivers/kbd.c to assign devno to keyboard.
 
1919 6518 d 9 h jermar /trunk/kernel/ Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only.
 
1912 6524 d 18 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1910 6528 d 7 h jermar /trunk/kernel/ Rename INO to INR, for the sake of consistency with manuals.  
1909 6529 d 9 h jermar /trunk/ Extend the OFW device tree node with a void pointer. The boot loader is
supposed to reset all pointers in all nodes. The kernel uses the pointer
to recognize that a particular device has already been visited and initialized.

Read interrupt mapping from the OFW device tree for FHC devices (z8530) and
EBUS devices (ns16550). In case of FHC devices, remove hardwired values from
the code and use only values read from the tree. FHC initialization is started
when a FHC device wants to map its interrupt. In case of EBUS devices, map
the interrupt to INO. Interrupt enabling in the interrupt controller for that
specific interrupt is not implemented yet.
 
1908 6531 d 19 h jermar /trunk/kernel/genarch/ Add function to find OFW tree node by handle.
