3186 5841 d 15 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 5842 d 14 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3183 5842 d 19 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3180 5844 d 0 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3143 5850 d 17 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5850 d 17 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5850 d 21 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.
 
3130 5853 d 2 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5853 d 15 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.
 
3104 5859 d 2 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3057 5861 d 19 h decky /trunk/kernel/generic/src/mm/ proper printf formatting  
3007 5869 d 15 h jermar /trunk/ Improve linking and loading of boot ELF images.

2745 5958 d 22 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5979 d 19 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 5984 d 19 h decky /trunk/kernel/ prettyprint output  
2647 6031 d 15 h jermar /trunk/kernel/generic/src/mm/ Fix a bug in anonymous address space area sharing. Call the backend's share
function only if the source area is not already shared. Otherwise increment the
sh_info refcount. Without this fix, the kernel will try to recreate the pagemap
if three and more address space areas attempt to share the same data.
 
2556 6109 d 23 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2467 6217 d 16 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2222 6283 d 13 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2183 6286 d 17 h jermar /trunk/kernel/generic/ Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();

Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!

Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.
