3233 5801 d 5 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3229 5801 d 9 h jermar /trunk/kernel/generic/include/ Improve definition of generic macros.  
3228 5801 d 17 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 5803 d 10 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5820 d 5 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5822 d 1 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.
 
3207 5822 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 5822 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 5822 d 4 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3198 5827 d 1 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5827 d 9 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5828 d 0 h jermar /trunk/kernel/ cstyle fixes  
3188 5834 d 22 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5835 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 5835 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.
 
3185 5836 d 1 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5836 d 5 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 5836 d 6 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5836 d 6 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5837 d 10 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5837 d 11 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5839 d 8 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 5844 d 4 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5844 d 4 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5844 d 8 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.
 
3137 5844 d 9 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5846 d 13 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5847 d 2 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.
 
3113 5851 d 21 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency
 
3104 5852 d 13 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3098 5854 d 1 h svoboda /trunk/ Make mips32 compile again  
3097 5854 d 1 h decky /trunk/kernel/ resurrect klog  
3096 5854 d 2 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3090 5855 d 5 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3068 5855 d 6 h decky /trunk/kernel/generic/include/ reflect changes in sources  
3067 5855 d 6 h decky /trunk/kernel/generic/include/ LOG, LOG_EXEC() macros (used if CONFIG_EDEBUG is set)
cosmetic changes
 
3066 5855 d 6 h decky /trunk/kernel/generic/include/ common types are same on all platforms  
3065 5855 d 6 h decky /trunk/kernel/generic/src/console/ remove original klog
permanent kernel cyclic log buffer
proper printf formatting
 
3064 5855 d 6 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting
 
3063 5855 d 6 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created
