3228 5815 d 19 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 5817 d 13 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5834 d 7 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5836 d 3 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.
 
3207 5836 d 3 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 5836 d 5 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 5836 d 7 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3198 5841 d 4 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5841 d 11 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5842 d 3 h jermar /trunk/kernel/ cstyle fixes  
3188 5849 d 0 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5849 d 4 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 5849 d 4 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 5850 d 4 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5850 d 7 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 5850 d 9 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5850 d 9 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5851 d 12 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5851 d 14 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5853 d 11 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 5858 d 7 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5858 d 7 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5858 d 10 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.
 
3137 5858 d 11 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5860 d 15 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5861 d 4 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.
 
3113 5866 d 0 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency
 
3104 5866 d 16 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3098 5868 d 4 h svoboda /trunk/ Make mips32 compile again  
3097 5868 d 4 h decky /trunk/kernel/ resurrect klog  
3096 5868 d 4 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3090 5869 d 8 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3068 5869 d 8 h decky /trunk/kernel/generic/include/ reflect changes in sources  
3067 5869 d 8 h decky /trunk/kernel/generic/include/ LOG, LOG_EXEC() macros (used if CONFIG_EDEBUG is set)
cosmetic changes
 
3066 5869 d 8 h decky /trunk/kernel/generic/include/ common types are same on all platforms  
3065 5869 d 8 h decky /trunk/kernel/generic/src/console/ remove original klog
permanent kernel cyclic log buffer
proper printf formatting
 
3064 5869 d 8 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting
 
3063 5869 d 8 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created
 
3062 5869 d 8 h decky /trunk/kernel/generic/src/proc/ proper printf formatting  
3061 5869 d 8 h decky /trunk/kernel/generic/src/main/ debugging output of kernel initialization
