4119 5580 d 23 h decky /trunk/ get back support for framebuffer and keyboard for sparc64 (generic)  
4114 5581 d 12 h jermar /trunk/ Fix one RAW dependency.  
4094 5581 d 14 h decky /trunk/kernel/genarch/ update for the new scheme of wiring device drivers to keyboard/serial modules  
4093 5581 d 14 h decky /trunk/kernel/genarch/src/ chardev_t -> outdev_t
small fixes and cleanups
 
4092 5581 d 14 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)
 
4079 5581 d 20 h decky /trunk/kernel/genarch/ support for dummy serial line input and output (e.g. msim)  
4078 5581 d 20 h decky /trunk/kernel/genarch/ add dummy serial line input and output drivers  
4052 5585 d 21 h jermar /trunk/kernel/genarch/src/srln/ Add a new line - gcc is very picky lately.  
4043 5586 d 15 h jermar /trunk/ Serial line module.  
4042 5586 d 16 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 5590 d 11 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 5590 d 12 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4011 5591 d 11 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3994 5591 d 18 h decky /trunk/kernel/genarch/src/drivers/ega/ make sure the EGA framebuffer is initialized with proper attributes  
3982 5593 d 13 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3981 5593 d 14 h jermar /trunk/kernel/genarch/src/kbd/ Get rid of unused variable.  
3975 5594 d 19 h decky /trunk/kernel/genarch/src/drivers/ega/ keep original contents of the EGA framebuffer,
make sure the cursor is on
 
3963 5599 d 16 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5599 d 17 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 5600 d 10 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3959 5600 d 10 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5600 d 10 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3947 5600 d 15 h jermar /trunk/ This is the evil commit. In particular, it does:

- introduces more powerful pseudo code for userspace IRQ top-half handlers
- changes the internals of IRQ dispatching
- simplifies the kernel's i8042 driver
- adapts the uspace i8042 driver to make use of the new pseudocode
- breaks all other architectures except ia32
- breaks almost all existing drivers
- breaks switching between uspace and kernel drivers
 
3941 5601 d 11 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5601 d 15 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3938 5601 d 15 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5602 d 8 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 5602 d 10 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3931 5602 d 10 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 5602 d 10 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3928 5602 d 12 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5602 d 12 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3908 5605 d 13 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3907 5605 d 22 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5606 d 9 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 5606 d 17 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.
 
3900 5606 d 18 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3877 5609 d 12 h decky /trunk/kernel/genarch/ remove (almost all) platform dependent code from drivers  
3876 5609 d 12 h decky /trunk/kernel/genarch/ add BGR 888 visual, remove FB_INVERT_ENDIAN  
3844 5621 d 11 h decky /trunk/ silent kernel console output when user space console is active
