3973 5610 d 12 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 5612 d 2 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.
 
3961 5615 d 8 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 5617 d 3 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5617 d 6 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3935 5617 d 23 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3908 5621 d 5 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5622 d 0 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.
 
3900 5622 d 10 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3880 5625 d 3 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3865 5629 d 1 h rimsky /trunk/ Allow to suppress compilation of FB code on Sparc machines that do not have FB.  
3852 5636 d 6 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3844 5637 d 2 h decky /trunk/ silent kernel console output when user space console is active  
3790 5660 d 11 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 5661 d 1 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3749 5672 d 23 h jermar /trunk/kernel/arch/sparc64/src/trap/ Support for preemptible syscalls on sparc64.  
3740 5674 d 7 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5675 d 9 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3714 5682 d 7 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3679 5692 d 23 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5694 d 4 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5700 d 3 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 5700 d 5 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 5701 d 1 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5701 d 2 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5701 d 4 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5718 d 16 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3482 5758 d 3 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 5770 d 8 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3458 5771 d 3 h jermar /trunk/kernel/arch/sparc64/src/trap/ Add sparc64 trap table entries so that the maximum syscall number is 0x40.  
3274 5811 d 8 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3222 5844 d 7 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3133 5869 d 3 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5876 d 16 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5879 d 9 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2860 5928 d 3 h cejka /trunk/ Context handling unified for sparc64.  
2745 5976 d 12 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5997 d 9 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)
 
2610 6079 d 7 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 6151 d 3 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.
