3240 5808 d 4 h decky / move unfinished ObjC support to a separate branch  
3233 5811 d 23 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3229 5812 d 3 h jermar /trunk/kernel/generic/include/ Improve definition of generic macros.  
3228 5812 d 11 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support
 
3225 5814 d 4 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5830 d 22 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5832 d 18 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.
 
3207 5832 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 5832 d 20 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 5832 d 22 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3198 5837 d 19 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5838 d 3 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5838 d 18 h jermar /trunk/kernel/ cstyle fixes  
3188 5845 d 16 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5845 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 5845 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 5846 d 19 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5846 d 23 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.
 
3183 5847 d 0 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5847 d 0 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5848 d 4 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5848 d 5 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5850 d 2 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.
 
3143 5854 d 22 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5854 d 22 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5855 d 2 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.
 
3137 5855 d 3 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5857 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 5857 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.
 
3113 5862 d 15 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency
 
3104 5863 d 7 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3098 5864 d 19 h svoboda /trunk/ Make mips32 compile again  
3097 5864 d 19 h decky /trunk/kernel/ resurrect klog  
3096 5864 d 20 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3090 5865 d 23 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3068 5866 d 0 h decky /trunk/kernel/generic/include/ reflect changes in sources  
3067 5866 d 0 h decky /trunk/kernel/generic/include/ LOG, LOG_EXEC() macros (used if CONFIG_EDEBUG is set)
cosmetic changes
 
3066 5866 d 0 h decky /trunk/kernel/generic/include/ common types are same on all platforms  
3065 5866 d 0 h decky /trunk/kernel/generic/src/console/ remove original klog
permanent kernel cyclic log buffer
proper printf formatting
 
3064 5866 d 0 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting
