3209 5856 d 18 h jermar /trunk/kernel/arch/ia32/src/smp/ Allocate AP's GDT from first 4 GiB.  
3208 5856 d 18 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.		  
3207 5856 d 19 h jermar /trunk/kernel/generic/ Introduce FRAME_LOW_16_GiB slab/frame allocator flag. When specified, the
allocators will not allocate memory above 16 GiB. Each architecture needs to
make sure not to merge zones from below and above 16 GiB. Allocations that
require memory below 16 GiB need to be altered to use this flag.		  
3206 5856 d 20 h jermar /trunk/kernel/generic/ Avoid deadlock during the 'zone n' kconsole command. Buddy allocator detail is
no longer printed because the effort to avoid the deadlock was simply not worth
it.		  
3205 5856 d 22 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3200 5860 d 2 h svoboda /trunk/kernel/arch/ppc32/src/ Remove buggy assembler memsetb function, call generic C _memsetb instead. Fixes kconsole panic when uspace klog is enabled and memsetb() called from klog_update()  
3198 5861 d 19 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5862 d 3 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5862 d 18 h jermar /trunk/kernel/ cstyle fixes  
3189 5867 d 17 h jermar /trunk/kernel/arch/ppc32/src/ Implement memcpy_to_uspace_failover_address for ppc32.
This fixes kernel side of ticket #59.		  
3188 5869 d 16 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5869 d 20 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 5869 d 20 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 5870 d 19 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5870 d 23 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 5871 d 0 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5871 d 0 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5872 d 4 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5872 d 5 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3179 5872 d 21 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 5874 d 2 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 5874 d 17 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 5874 d 17 h jermar /trunk/kernel/ Frame pointers will make debugging much easier.  
3167 5875 d 5 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 5875 d 17 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 5876 d 17 h jermar /trunk/ First argument of atomic functions is read-write (ia32).  
3163 5876 d 17 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3162 5876 d 17 h jermar /trunk/ The first argument to atomic_add() is read-write. (mips32)  
3145 5878 d 6 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 5878 d 22 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5878 d 22 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5879 d 2 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3140 5879 d 2 h jermar /trunk/kernel/arch/ia64/include/ Fix operands for fc_i().  
3139 5879 d 2 h jermar /trunk/kernel/arch/mips32/src/ Maintain cache coherence when setting breakpoints in kconsole on mips32.  
3138 5879 d 3 h jermar /trunk/kernel/arch/amd64/src/ Formatting fixes for amd64 debugger.  
3137 5879 d 3 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3136 5879 d 3 h jermar /trunk/kernel/arch/mips32/src/ Maintain cache coherence after mips32 install exception handlers.  
3135 5879 d 3 h jermar /trunk/kernel/arch/arm32/src/ Maintain cache coherence after arm32 installs exception handlers.  
3134 5879 d 4 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5879 d 18 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
