2474 6181 d 21 h jermar /tags/0.2.0.5/ Add tag for HelenOS 0.2.0.5.  
2467 6187 d 2 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6192 d 4 h jermar /trunk/ Merge arm32 into trunk.  
2462 6193 d 23 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6193 d 23 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6194 d 2 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 6194 d 3 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2457 6194 d 3 h jermar /trunk/kernel/arch/ia32xen/src/smp/ Fix ia32xen so that it can be built.  
2454 6194 d 22 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 6195 d 4 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 6195 d 5 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 6199 d 20 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2441 6199 d 22 h decky /trunk/kernel/ fix ICC compilation  
2439 6199 d 22 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6199 d 22 h decky /trunk/ update for new compiler configuration scheme  
2317 6221 d 20 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6221 d 20 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6221 d 21 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2302 6227 d 2 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2272 6242 d 1 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6244 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6244 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6245 d 22 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 6251 d 22 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6251 d 23 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6252 d 3 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 6252 d 6 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6252 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6252 d 13 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 6252 d 22 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 6253 d 0 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6253 d 0 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 6253 d 1 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6253 d 20 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 6253 d 21 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 6253 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2170 6260 d 21 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 6263 d 0 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 6263 d 21 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.  
2143 6264 d 4 h jermar /trunk/kernel/arch/sparc64/include/ Remove unneeded enum member.
