4490 5462 d 4 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4303 5508 d 9 h jermar /trunk/kernel/generic/src/mm/ Allow malloc(0, ...) in kernel.  
4230 5522 d 22 h decky /trunk/kernel/generic/src/mm/ avoid deadlock while reclaiming slab memory  
4174 5533 d 21 h decky /trunk/kernel/generic/ add malloc slab caches for up to 4 MB blocks  
4048 5550 d 2 h jermar /trunk/kernel/generic/src/mm/ Fix non-debug build.  
3973 5558 d 13 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()		  
3972 5559 d 0 h decky /trunk/kernel/ kernel memory management revisited (phase 1): proper support for zone flags
- the zone_t structures are now statically allocated to be easily available
- the locking scheme was simplified
- new flags for non-available zones were introduced
- FRAME_LOW_4_GiB flag is removed, the functionality will be eventually reimplemented using a generic mechanism		  
3913 5568 d 10 h decky /trunk/ mips32: basic SMP support  
3790 5608 d 12 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3707 5631 d 5 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3626 5654 d 8 h vana /trunk/kernel/ Classic TLB shootdown support on ia64  
3578 5666 d 16 h vana /trunk/ Alfa of SMP support on IA64  
3422 5724 d 2 h jermar /trunk/kernel/generic/src/mm/ as_area_resize() should use as instead of AS.  
3384 5736 d 5 h jermar /trunk/kernel/generic/src/mm/ cstyle  
3383 5736 d 14 h svoboda /trunk/kernel/generic/src/mm/ Fix panic caused by not setting new area flags in as_area_change_flags(), as pointed out by Jakub.  
3382 5737 d 3 h jermar /trunk/kernel/generic/src/mm/ Fix the rare case when the anon or ELF backend uses PFN 0 for mapping.  
3240 5769 d 13 h decky / move unfinished ObjC support to a separate branch  
3222 5792 d 8 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5794 d 4 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.		  
3207 5794 d 4 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 5794 d 6 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 5794 d 8 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3188 5807 d 1 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5807 d 5 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 5807 d 5 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 5808 d 5 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3183 5808 d 9 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3180 5809 d 15 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3143 5816 d 8 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5816 d 8 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5816 d 11 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3130 5818 d 16 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5819 d 5 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3104 5824 d 16 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3057 5827 d 9 h decky /trunk/kernel/generic/src/mm/ proper printf formatting  
3007 5835 d 5 h jermar /trunk/ Improve linking and loading of boot ELF images.
(Contributed by Jiri Svoboda)		  
2745 5924 d 12 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5945 d 10 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 5950 d 10 h decky /trunk/kernel/ prettyprint output  
2647 5997 d 5 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.
