3206 5863 d 21 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.		  
/trunk/kernel/generic/include/mm/buddy.h
/trunk/kernel/generic/src/mm/buddy.c
/trunk/kernel/generic/src/mm/frame.c
3205 5863 d 23 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
/trunk/kernel/generic/src/mm/frame.c
3194 5869 d 4 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.

3193 5869 d 19 h jermar /trunk/kernel/ cstyle fixes

3188 5876 d 17 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
/trunk/kernel/generic/src/mm/frame.c
3187 5876 d 21 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.		  
/trunk/kernel/generic/src/mm/frame.c
3186 5876 d 21 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.

/trunk/kernel/generic/src/mm/frame.c
3184 5878 d 0 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.		  
/trunk/kernel/generic/src/ipc/ipc.c
3183 5878 d 1 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
/trunk/kernel/generic/src/mm/slab.c
3181 5879 d 5 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
/trunk/kernel/generic/src/main/kinit.c
/trunk/kernel/generic/src/proc/scheduler.c
3180 5879 d 7 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
/trunk/kernel/generic/src/mm/slab.c
3175 5881 d 3 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.		  
/trunk/kernel/generic/src/main/main.c
3143 5885 d 23 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
/trunk/kernel/arch/ppc32/include/barrier.h
/trunk/kernel/generic/src/mm/backend_elf.c
3142 5886 d 0 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
/trunk/kernel/generic/src/mm/backend_elf.c
3141 5886 d 3 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
/trunk/kernel/generic/src/mm/backend_elf.c
3137 5886 d 4 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
/trunk/kernel/generic/src/proc/task.c
3130 5888 d 8 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
/trunk/kernel/generic/src/mm/page.c
3128 5888 d 21 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
/trunk/kernel/generic/src/mm/page.c
3113 5893 d 16 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency
