3187 5895 d 19 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 5895 d 19 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 5896 d 18 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5896 d 22 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 5896 d 23 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5896 d 23 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5898 d 3 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5898 d 4 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5900 d 1 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 5904 d 21 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5904 d 21 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5905 d 1 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3137 5905 d 2 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5907 d 6 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5907 d 19 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3113 5912 d 14 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3104 5913 d 6 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3098 5914 d 18 h svoboda /trunk/ Make mips32 compile again  
3097 5914 d 18 h decky /trunk/kernel/ resurrect klog  
3096 5914 d 19 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()
