3549 5771 d 21 h rimsky /branches/sparc/ Implemented uspace Serengeti drivers for kbd and fb. Integrated with other parts of HelenOS. Now it is possible to play Tetris on a simulated Serengeti machine (usiii.simics).  
3514 5780 d 21 h rimsky /branches/sparc/ Input support added to SGCN driver, connected to HelenOS kernel (uspace TBD), so that kconsole is usable.  
3502 5781 d 22 h rimsky /branches/sparc/ Implemented Serengeti console driver (only output, input TBD), all output now goes to the console instead of Simics CLI window.  
3493 5789 d 23 h rimsky /branches/sparc/ More changes making the code US-III-conformant (mainly in mm).  
3492 5793 d 1 h rimsky /branches/sparc/ Changes in trunk merged into the sparc branch. SILO's ramdisk issue solved by the CONFIG_RD_EXTERNAL option.  
3489 5797 d 1 h rimsky /branches/sparc/ More files made conform the US-III specification. (Changes concern mainly TSB.)  
3479 5808 d 6 h rimsky /branches/sparc/ Names containing 'UPA' replaced with strings containing more general 'ICBUS'. SMART_FIRMWARE option replaced with CPU autodetection + new option CONFIG_A_OUT_ISOFS_B.  
3477 5812 d 0 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3467 5814 d 23 h rimsky /branches/sparc/ SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.  
3450 5818 d 23 h rimsky /branches/sparc/kernel/arch/sparc64/ Made tlb.h conform US-III specification.  
3440 5820 d 7 h rimsky /branches/sparc/kernel/arch/sparc64/ TLB modifications in order to make functions tlb_print and tlb_invalidate_all work correctly in US-III.  
3398 5825 d 6 h rimsky /branches/sparc/ US used as a code for the UltraSPARC I-II subarchitecture instead of US2.  
3397 5825 d 6 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3365 5842 d 22 h rimsky /branches/sparc/ Integrated US-III port into the build process; added script for downloading and patching SILO; added patched SILO binaries; modified sources of the Sparc64 port up to the beginning of the main_bsp_separated_stack function: phys. address size not hardwired but configurable (41 bits on US-II, 43 bits on US-III), WSTATE register implicitly written 0 on startup.  
3343 5849 d 3 h decky /branches/sparc/ add sparc branch  
3274 5858 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.
 
3233 5872 d 5 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3222 5891 d 4 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3145 5914 d 12 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 5915 d 10 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5915 d 23 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5923 d 12 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5926 d 5 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
3070 5926 d 5 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
2860 5975 d 0 h cejka /trunk/ Context handling unified for sparc64.  
2797 5987 d 0 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5988 d 0 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2745 6023 d 8 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6044 d 6 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 6045 d 6 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2610 6126 d 4 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 6198 d 0 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 6289 d 0 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6289 d 0 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2454 6289 d 23 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 6337 d 2 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6339 d 1 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6339 d 1 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6340 d 23 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 6347 d 4 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.
