3187 5860 d 23 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 23 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 22 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5862 d 2 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 5862 d 3 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3181 5863 d 7 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5863 d 8 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5865 d 5 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 5870 d 1 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5870 d 2 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5870 d 5 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3137 5870 d 6 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5872 d 10 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 23 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3113 5877 d 18 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3104 5878 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3097 5879 d 22 h decky /trunk/kernel/ resurrect klog  
3096 5879 d 23 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3090 5881 d 2 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3065 5881 d 3 h decky /trunk/kernel/generic/src/console/ remove original klog
permanent kernel cyclic log buffer
proper printf formatting
