3973 5730 d 9 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 5730 d 21 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 5740 d 6 h decky /trunk/ mips32: basic SMP support  
3790 5780 d 8 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 5803 d 1 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3626 5826 d 4 h vana /trunk/kernel/ Classic TLB shootdown support on ia64  
3578 5838 d 12 h vana /trunk/ Alfa of SMP support on IA64  
3422 5895 d 23 h jermar /trunk/kernel/generic/src/mm/ as_area_resize() should use as instead of AS.  
3384 5908 d 1 h jermar /trunk/kernel/generic/src/mm/ cstyle  
3383 5908 d 11 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 5908 d 23 h jermar /trunk/kernel/generic/src/mm/ Fix the rare case when the anon or ELF backend uses PFN 0 for mapping.  
3240 5941 d 10 h decky / move unfinished ObjC support to a separate branch  
3222 5964 d 4 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5966 d 0 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.		  
3207 5966 d 1 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 5966 d 2 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 5966 d 4 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3188 5978 d 21 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5979 d 2 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 5979 d 2 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.
