4071 5642 d 2 h jermar /trunk/kernel/arch/sparc64/ Some additional fixes to the sgcn driver.  
4070 5642 d 4 h rimsky /trunk/ SGCN driver modified to reflect the new keyboard driver architecture. Making the Serengeti bootable image smaller by not including some servers/applications.  
4032 5648 d 2 h svoboda /trunk/ Init-task names for sparc64 (that's the final one, whew).  
4021 5650 d 1 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
3973 5654 d 10 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()
 
3961 5659 d 6 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.
 
3929 5662 d 0 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 5663 d 23 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 5665 d 3 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5665 d 22 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 5666 d 6 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.
 
3880 5669 d 1 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3878 5669 d 1 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5708 d 7 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3740 5718 d 5 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5719 d 8 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3722 5723 d 12 h rimsky /trunk/kernel/arch/sparc64/include/ SMC functions optimized for US3.  
3672 5738 d 2 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5744 d 1 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 5744 d 3 h jermar /trunk/kernel/arch/sparc64/ After my effort yesterday, there are two rival psycho drivers.
Merge the two and remove the newer one.
 
3647 5745 d 0 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3580 5761 d 23 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.
 
3577 5762 d 14 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3482 5802 d 1 h jermar /trunk/kernel/arch/sparc64/ Do not allocate full page for the uspace window buffer.
Instead, allocate only the bare minimum to fit NWINDOWS - 1
uspace windows and to satisfy alignment requirements.
 
3463 5814 d 6 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3379 5834 d 12 h jermar /trunk/kernel/arch/sparc64/include/ Add the missing preemption_disable() call to sparc64 atomic_lock_arch().
Thanks to Pavel Rimsky for noticing this.
 
3233 5869 d 6 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3145 5911 d 13 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, when the operand to the FLUSH instruction doesn't matter, the
instruction's semantics is to flush the pipeline.
 
3134 5912 d 11 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5913 d 1 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5920 d 14 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5923 d 7 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
3070 5923 d 7 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
2860 5972 d 2 h cejka /trunk/ Context handling unified for sparc64.  
2797 5984 d 2 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5985 d 1 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2725 6041 d 7 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2721 6042 d 8 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2610 6123 d 5 h jermar /trunk/ Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task).
 
2510 6195 d 2 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.
