3222 5867 d 6 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5869 d 2 h jermar /trunk/kernel/generic/ The real intention of the previous commit was to put the boundary
on 4 GiB, not 16 GiB.		  
3207 5869 d 2 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 5869 d 4 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 5869 d 6 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3198 5874 d 3 h svoboda /trunk/ Use initrd with mips32 port. Increase memory size.  
3194 5874 d 10 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5875 d 1 h jermar /trunk/kernel/ cstyle fixes  
3188 5881 d 23 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5882 d 3 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 5882 d 3 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 5883 d 3 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5883 d 6 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 5883 d 7 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3182 5883 d 7 h jermar /trunk/kernel/generic/include/mm/ cstyle for slab.h  
3181 5884 d 11 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5884 d 13 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5886 d 10 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 5891 d 5 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5891 d 6 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5891 d 9 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3137 5891 d 10 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5893 d 14 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5894 d 3 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3113 5898 d 23 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3104 5899 d 14 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3098 5901 d 2 h svoboda /trunk/ Make mips32 compile again  
3097 5901 d 3 h decky /trunk/kernel/ resurrect klog  
3096 5901 d 3 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3090 5902 d 7 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3068 5902 d 7 h decky /trunk/kernel/generic/include/ reflect changes in sources  
3067 5902 d 7 h decky /trunk/kernel/generic/include/ LOG, LOG_EXEC() macros (used if CONFIG_EDEBUG is set)
cosmetic changes		  
3066 5902 d 7 h decky /trunk/kernel/generic/include/ common types are same on all platforms  
3065 5902 d 7 h decky /trunk/kernel/generic/src/console/ remove original klog
permanent kernel cyclic log buffer
proper printf formatting		  
3064 5902 d 7 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting		  
3063 5902 d 7 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created		  
3062 5902 d 7 h decky /trunk/kernel/generic/src/proc/ proper printf formatting  
3061 5902 d 7 h decky /trunk/kernel/generic/src/main/ debugging output of kernel initialization  
3060 5902 d 7 h decky /trunk/kernel/generic/src/main/ run init tasks after they are all loaded  
3059 5902 d 7 h decky /trunk/kernel/generic/src/ proper printf formatting
