3655 5741 d 19 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 5741 d 21 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 5742 d 16 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5742 d 18 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5742 d 20 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3580 5759 d 17 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 5760 d 7 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3482 5799 d 19 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 5812 d 0 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3458 5812 d 19 h jermar /trunk/kernel/arch/sparc64/src/trap/ Add sparc64 trap table entries so that the maximum syscall number is 0x40.  
3379 5832 d 6 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 5835 d 23 h decky /trunk/ configurable cross-compiler prefix (using CROSS_PREFIX)  
3274 5853 d 0 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.		  
3233 5867 d 0 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3222 5885 d 23 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3145 5909 d 7 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 5910 d 5 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5910 d 18 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.		  
3104 5918 d 8 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5921 d 0 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
3070 5921 d 0 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types		  
2860 5969 d 19 h cejka /trunk/ Context handling unified for sparc64.  
2797 5981 d 19 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.		  
2794 5982 d 19 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2745 6018 d 3 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6039 d 1 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 6040 d 1 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2610 6120 d 23 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 6192 d 19 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.		  
2462 6283 d 19 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.		  
2460 6283 d 19 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.		  
2454 6284 d 18 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.		  
2272 6331 d 21 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6333 d 20 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6333 d 20 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6335 d 18 h jermar /trunk/kernel/arch/sparc64/src/mm/ Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be.		  
2231 6341 d 23 h jermar /trunk/kernel/arch/sparc64/ Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur.		  
2228 6342 d 1 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.		  
2227 6342 d 9 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6343 d 19 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
