3187 5860 d 9 h jermar /trunk/kernel/generic/src/mm/ Get rid of the infamous "Sleep not implemented" panic during low memory
condition. Use a condition variable to implement the sleep. As of now, the
condition is rather coarse and can cause that threads may sleep unnecessarily.
Needs to be fine tuned and based on the amount of memory available.
 
3186 5860 d 9 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.
 
3185 5861 d 9 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5861 d 12 h jermar /trunk/kernel/generic/src/ipc/ Fix a scary two-year old bug: do not attempt to initialize a call structure if
its allocation failed.
 
3183 5861 d 13 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5861 d 13 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5862 d 17 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5862 d 19 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3179 5863 d 11 h jermar /trunk/kernel/ Introduce the notion of FPU_NO_CFLAGS and separate building of test/fpu
objects and building the rest of kernel objects. Now, amd64 and ia32 can
enable things such as SSE selectively for the test/fpu/*.
 
3175 5864 d 16 h jermar /trunk/kernel/generic/src/main/ Don't print anything before the kernel initializes the first THE
structure. This fixes a regression introduced in r3061. If anything
worked from r3061 until now, it was only due to luck. arm32 was not
that lucky when built with gcc 4.3.1.
 
3173 5865 d 7 h jermar /trunk/kernel/arch/ia32/ Don't build the ia32 kernel with MMX/SSE/3DNOW enabled. This was causing
problems with gcc 4.3.1 which generated MMX aided code in a context that
didn't allow this.
 
3172 5865 d 7 h jermar /trunk/kernel/ Frame pointers will make debugging much easier.  
3167 5865 d 18 h svoboda /trunk/kernel/arch/mips32/include/ Fix mips32 atomic_add() which would break build unless a constant was propagated into the second argument. (Specifically at -O0)  
3165 5866 d 7 h jermar /trunk/kernel/test/avltree/ Fix an off-by-one bug in avltree1 test and also declare an unused static
function as used. These two bugs were breaking building by gcc 4.3.1.
 
3164 5867 d 6 h jermar /trunk/ First argument of atomic functions is read-write (ia32).  
3163 5867 d 6 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3162 5867 d 7 h jermar /trunk/ The first argument to atomic_add() is read-write. (mips32)  
3145 5868 d 20 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.
 
3143 5869 d 12 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5869 d 12 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5869 d 15 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.
 
3140 5869 d 15 h jermar /trunk/kernel/arch/ia64/include/ Fix operands for fc_i().  
3139 5869 d 16 h jermar /trunk/kernel/arch/mips32/src/ Maintain cache coherence when setting breakpoints in kconsole on mips32.  
3138 5869 d 16 h jermar /trunk/kernel/arch/amd64/src/ Formatting fixes for amd64 debugger.  
3137 5869 d 16 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3136 5869 d 16 h jermar /trunk/kernel/arch/mips32/src/ Maintain cache coherence after mips32 install exception handlers.  
3135 5869 d 16 h jermar /trunk/kernel/arch/arm32/src/ Maintain cache coherence after arm32 installs exception handlers.  
3134 5869 d 18 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5870 d 7 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3130 5871 d 20 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5872 d 9 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.
 
3118 5876 d 13 h jermar /trunk/kernel/test/mm/ Fix formatter.  
3113 5877 d 5 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency
 
3105 5877 d 20 h svoboda /trunk/kernel/ Revert accidental change of Makefile  
3104 5877 d 20 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3098 5879 d 8 h svoboda /trunk/ Make mips32 compile again  
3097 5879 d 9 h decky /trunk/kernel/ resurrect klog  
3096 5879 d 9 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3095 5879 d 9 h svoboda /trunk/ Make ia64 compile again.  
3094 5879 d 9 h svoboda /trunk/ Make arm32 compile again.
