3403 5797 d 6 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3168 5885 d 4 h svoboda /branches/dynload/ For each arch define one register for passing a pointer to PCB. Implemented in kernel lowlevel swich-to-userspace funcs and libc entry points. Missing in loader's program_run implementations.  
3153 5887 d 3 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
3149 5887 d 4 h svoboda /branches/dynload/ Merge trunk changes up to r3071 into dynload (broken)  
2927 5919 d 7 h decky /branches/dynload/ added dynload branch  
2860 5948 d 21 h cejka /trunk/ Context handling unified for sparc64.  
2797 5960 d 21 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5961 d 20 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2745 5997 d 5 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6018 d 2 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 6019 d 3 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2610 6100 d 0 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 6171 d 21 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 6262 d 20 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6262 d 21 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2454 6263 d 19 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 6310 d 22 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6312 d 21 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6312 d 22 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6314 d 20 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 6321 d 0 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 6321 d 3 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6321 d 10 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6322 d 21 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2170 6329 d 18 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 6331 d 21 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 6332 d 19 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.  
2143 6333 d 1 h jermar /trunk/kernel/arch/sparc64/include/ Remove unneeded enum member.  
2141 6333 d 17 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
