2477 6247 d 22 h kebrt /trunk/kernel/arch/arm32/src/ fixes bug causing crash in tester 'thread1' test  
2467 6255 d 4 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6260 d 6 h jermar /trunk/ Merge arm32 into trunk.  
2462 6262 d 1 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 1 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6262 d 5 h jermar /trunk/kernel/arch/ Fix a bug in ia32 and ia32xen Sun Studio builds.
In arch Makefile.inc, SUNCC_CFLAGS can only be appended via the += operator.
 
2458 6262 d 5 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2457 6262 d 5 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2454 6263 d 0 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.
 
2453 6263 d 6 h jermar /trunk/kernel/ More suncc fixes.
- remove more empty declarations
- add options to turn errors on empty structs into warnings and options to
silence these warnings
 
2452 6263 d 7 h jermar /trunk/kernel/ More suncc fixes.
- Removed extra semicolons after function declaration.
- Sun Studio recognizes only C99 __func__ and no gcc-specific __FUNCTION__.
In this case, a simple -D option can fix the problem.
 
2444 6267 d 22 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2441 6268 d 0 h decky /trunk/kernel/ fix ICC compilation  
2439 6268 d 0 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6268 d 0 h decky /trunk/ update for new compiler configuration scheme  
2317 6289 d 22 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6289 d 22 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6289 d 23 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2302 6295 d 4 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2272 6310 d 3 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6312 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6312 d 3 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6314 d 0 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.
 
2233 6320 d 0 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6320 d 1 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6320 d 5 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 6320 d 8 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6320 d 15 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6320 d 15 h decky /trunk/kernel/arch/mips32/ the bss and common sections have to be in .data output section to be properly generated in the binary image
(this might break IRIX, but it is already unmaintaned)
 
2222 6321 d 1 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2221 6321 d 2 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6321 d 2 h decky /trunk/kernel/arch/ia32/src/boot/ check for PSE support, add error message on PSE not present
make initial mapping explicitly writeable, turn PAE explicitly off (just in case)
 
2219 6321 d 3 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6321 d 22 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)
 
2217 6321 d 23 h jermar /trunk/kernel/arch/ia32/src/smp/ On SMP amd64 and ia32 systems, release the irq->lock
before calling clock() from the interrupt handler.
This is important for maintaining kernel preemption
since no preemption can take place while a spinlock
is held.
 
2216 6322 d 1 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2170 6328 d 23 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 2 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 6331 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.  
2143 6332 d 6 h jermar /trunk/kernel/arch/sparc64/include/ Remove unneeded enum member.
