3969 5645 d 23 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.
 
3961 5649 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.
 
3941 5651 d 0 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5651 d 4 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3935 5651 d 21 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3929 5651 d 23 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 5653 d 22 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 5655 d 2 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5655 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 5656 d 5 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 5656 d 7 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3880 5659 d 1 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3879 5659 d 1 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5659 d 1 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3865 5662 d 22 h rimsky /trunk/ Allow to suppress compilation of FB code on Sparc machines that do not have FB.  
3852 5670 d 3 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3844 5670 d 23 h decky /trunk/ silent kernel console output when user space console is active  
3790 5694 d 9 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 5694 d 22 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 5698 d 7 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3749 5706 d 20 h jermar /trunk/kernel/arch/sparc64/src/trap/ Support for preemptible syscalls on sparc64.  
3740 5708 d 4 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5709 d 7 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3722 5713 d 11 h rimsky /trunk/kernel/arch/sparc64/include/ SMC functions optimized for US3.  
3714 5716 d 4 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3679 5726 d 20 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5728 d 1 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5734 d 0 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 5734 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.
 
3649 5734 d 22 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5735 d 0 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5735 d 1 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3580 5751 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 5752 d 13 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3482 5792 d 0 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 5804 d 6 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3458 5805 d 0 h jermar /trunk/kernel/arch/sparc64/src/trap/ Add sparc64 trap table entries so that the maximum syscall number is 0x40.  
3379 5824 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.
 
3368 5828 d 5 h decky /trunk/ configurable cross-compiler prefix (using CROSS_PREFIX)  
3274 5845 d 5 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.
