4022 5588 d 8 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 5588 d 9 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4011 5589 d 8 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3994 5589 d 15 h decky /trunk/kernel/genarch/src/drivers/ega/ make sure the EGA framebuffer is initialized with proper attributes  
3982 5591 d 10 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3981 5591 d 11 h jermar /trunk/kernel/genarch/src/kbd/ Get rid of unused variable.  
3975 5592 d 16 h decky /trunk/kernel/genarch/src/drivers/ega/ keep original contents of the EGA framebuffer,
make sure the cursor is on
 
3963 5597 d 13 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5597 d 14 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 5598 d 7 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3959 5598 d 7 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5598 d 7 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3947 5598 d 12 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 5599 d 8 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5599 d 12 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3938 5599 d 12 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5600 d 5 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 5600 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 5600 d 7 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 5600 d 7 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3928 5600 d 9 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5600 d 9 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3908 5603 d 10 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3907 5603 d 19 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5604 d 6 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 5604 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.
 
3900 5604 d 15 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3877 5607 d 9 h decky /trunk/kernel/genarch/ remove (almost all) platform dependent code from drivers  
3876 5607 d 9 h decky /trunk/kernel/genarch/ add BGR 888 visual, remove FB_INVERT_ENDIAN  
3844 5619 d 8 h decky /trunk/ silent kernel console output when user space console is active  
3790 5642 d 17 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 5646 d 15 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3752 5654 d 17 h svoboda /trunk/kernel/genarch/src/fb/ Another memmove() instead of memcpy().  
3741 5656 d 12 h jermar /trunk/kernel/genarch/src/fb/ cstyle  
3733 5657 d 15 h decky /trunk/kernel/genarch/src/fb/ fix console overdrawing when is logo on  
3714 5664 d 13 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3710 5665 d 8 h decky /trunk/ resurrect kernel logo  
3709 5665 d 10 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5665 d 10 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
 
3704 5665 d 10 h decky /trunk/kernel/genarch/include/kbd/ add header
