4637 5442 d 19 h svoboda /trunk/kernel/genarch/ Implement data transmission to CUDA, use to enable autopolling. Now the driver works both in PearPC and Qemu -M g3beige.  
4626 5446 d 19 h svoboda /trunk/kernel/genarch/ Modify CUDA driver to state machine format, with one interrupt per byte transferred.  
4610 5451 d 21 h svoboda /trunk/ Kernel Mac ADB keyboard driver revived.  
4311 5524 d 4 h decky /trunk/ change the way how input devices are wired together according to ticket #44
(also the proposal http://lists.modry.cz/cgi-bin/private/helenos-devel/2009-March/002507.html)
 
4251 5539 d 0 h decky /trunk/kernel/ ia32, amd64: do not reboot via a triple fault (which is nasty), but use the i8042 controller to trigger CPU reset  
4223 5542 d 1 h decky /trunk/kernel/ represent special keystrokes (cursor arrows, page up/down, delete, etc.) as appropriate Unicode characters
do not parse ANSI control sequences in kconsole, but in serial line driver
 
4187 5552 d 0 h decky /trunk/ simplify glyph mapping function
draw invalid glyphs with a distinctive color
 
4177 5552 d 2 h decky /trunk/kernel/genarch/ use Unicode font glyphs and mapping for framebuffer  
4148 5558 d 5 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
 
4119 5563 d 7 h decky /trunk/ get back support for framebuffer and keyboard for sparc64 (generic)  
4114 5563 d 20 h jermar /trunk/ Fix one RAW dependency.  
4094 5563 d 22 h decky /trunk/kernel/genarch/ update for the new scheme of wiring device drivers to keyboard/serial modules  
4092 5563 d 22 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 5564 d 4 h decky /trunk/kernel/genarch/ add dummy serial line input and output drivers  
4043 5569 d 0 h jermar /trunk/ Serial line module.  
4042 5569 d 0 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 5572 d 19 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 5572 d 20 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
3963 5582 d 1 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5582 d 1 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 5582 d 18 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3941 5583 d 19 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5583 d 23 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3938 5584 d 0 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5584 d 16 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 5584 d 18 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3931 5584 d 18 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 5584 d 18 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3927 5584 d 21 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3907 5588 d 6 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5588 d 17 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 5589 d 1 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 5591 d 20 h decky /trunk/kernel/genarch/ add BGR 888 visual, remove FB_INVERT_ENDIAN  
3779 5631 d 2 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3710 5649 d 19 h decky /trunk/ resurrect kernel logo  
3707 5649 d 21 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3704 5649 d 21 h decky /trunk/kernel/genarch/include/kbd/ add header  
3679 5659 d 16 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5660 d 20 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5666 d 20 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.
