3188 5817 d 0 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5817 d 4 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 5817 d 4 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 5818 d 3 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5818 d 7 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 5818 d 8 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5818 d 8 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5819 d 12 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5819 d 14 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5821 d 10 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.		  
3143 5826 d 6 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5826 d 7 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5826 d 10 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3137 5826 d 11 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5828 d 15 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5829 d 4 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3113 5833 d 23 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3104 5834 d 15 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3098 5836 d 3 h svoboda /trunk/ Make mips32 compile again  
3097 5836 d 3 h decky /trunk/kernel/ resurrect klog
