3646 5672 d 15 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3580 5689 d 13 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 5690 d 3 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3482 5729 d 14 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 5741 d 20 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3458 5742 d 14 h jermar /trunk/kernel/arch/sparc64/src/trap/ Add sparc64 trap table entries so that the maximum syscall number is 0x40.  
3379 5762 d 2 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 5765 d 18 h decky /trunk/ configurable cross-compiler prefix (using CROSS_PREFIX)  
3274 5782 d 19 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 5796 d 20 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3222 5815 d 19 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3145 5839 d 2 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 5840 d 0 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5840 d 14 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.		  
3104 5848 d 3 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5850 d 20 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
3070 5850 d 20 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types		  
2860 5899 d 15 h cejka /trunk/ Context handling unified for sparc64.  
2797 5911 d 15 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.		  
2794 5912 d 15 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2745 5947 d 23 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5968 d 20 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 5969 d 21 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2610 6050 d 18 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 6122 d 15 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 6213 d 14 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.		  
2460 6213 d 15 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.		  
2454 6214 d 13 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 6261 d 16 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6263 d 15 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6263 d 16 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6265 d 14 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 6271 d 18 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 6271 d 21 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.		  
2227 6272 d 5 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6273 d 15 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2170 6280 d 12 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2161 6282 d 15 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB bug during TSB refill.
When one wants to enable a TSB entry, he or she should set the
entry invalid bit to false, as opposed to setting it to true.		  
2144 6283 d 13 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.  
2143 6283 d 19 h jermar /trunk/kernel/arch/sparc64/include/ Remove unneeded enum member.
