3207 5888 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 5888 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.		  
3205 5888 d 23 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3188 5901 d 16 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5901 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 5901 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 5902 d 20 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3183 5903 d 1 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3180 5904 d 6 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3143 5910 d 23 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5910 d 23 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5911 d 2 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3130 5913 d 7 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5913 d 20 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3104 5919 d 8 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3057 5922 d 0 h decky /trunk/kernel/generic/src/mm/ proper printf formatting  
3007 5929 d 20 h jermar /trunk/ Improve linking and loading of boot ELF images.
(Contributed by Jiri Svoboda)		  
2745 6019 d 3 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6040 d 1 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2712 6045 d 1 h decky /trunk/kernel/ prettyprint output
