4026 5603 d 14 h jermar /trunk/ Make the kbd port drivers platform neutral by using PIO functions.
The kernel now supplies the physical address and the kernel virtual address.
 
4023 5603 d 15 h svoboda /trunk/kernel/arch/ Unify arch_pre_main() comments.  
4021 5603 d 16 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4011 5604 d 15 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3982 5606 d 18 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3978 5607 d 16 h jermar /trunk/ Userspace driver for OBIO. This will make it possible to clear interrupts from
user space on UltraSPARC IIi and systems with Psycho. Not tested.
 
3973 5608 d 1 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()
 
3969 5609 d 15 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.
 
3961 5612 d 21 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.
 
3941 5614 d 16 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5614 d 19 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3935 5615 d 13 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3929 5615 d 15 h jermar /trunk/kernel/arch/ Introduce ioport8_t, ioport16_t and ioport32_t. These types are to be used with
pio_read_n() and pio_write_n() functions. This breaks everything.
 
3922 5617 d 14 h decky /trunk/ make arch_pre_main optional, don't force any specific prototype
simplify boot process
mips32: detect number of configured CPUs in msim
 
3908 5618 d 18 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5619 d 14 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 5619 d 21 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 5619 d 23 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3880 5622 d 17 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3879 5622 d 17 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5622 d 17 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3865 5626 d 14 h rimsky /trunk/ Allow to suppress compilation of FB code on Sparc machines that do not have FB.  
3852 5633 d 19 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3844 5634 d 15 h decky /trunk/ silent kernel console output when user space console is active  
3790 5658 d 1 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.  
3788 5658 d 14 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3779 5661 d 23 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3749 5670 d 12 h jermar /trunk/kernel/arch/sparc64/src/trap/ Support for preemptible syscalls on sparc64.  
3740 5671 d 20 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5672 d 23 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3722 5677 d 3 h rimsky /trunk/kernel/arch/sparc64/include/ SMC functions optimized for US3.  
3714 5679 d 20 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3679 5690 d 12 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5691 d 17 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5697 d 16 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.
 
3654 5697 d 19 h jermar /trunk/kernel/arch/sparc64/ After my effort yesterday, there are two rival psycho drivers.
Merge the two and remove the newer one.
 
3649 5698 d 14 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5698 d 16 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5698 d 17 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3580 5715 d 15 h jermar /trunk/kernel/arch/sparc64/include/ Accesses to memory mapped registers should use volatile pointers so that
the compiler doesn't even think of trying to be clever. Add memory barriers
and fixed cstyle.
