3194 5840 d 5 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5840 d 20 h jermar /trunk/kernel/ cstyle fixes  
3188 5847 d 18 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.		  
3187 5847 d 22 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 5847 d 22 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 5848 d 22 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5849 d 1 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 5849 d 2 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3181 5850 d 6 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5850 d 8 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c  
3175 5852 d 5 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 5857 d 0 h svoboda /trunk/kernel/ Implement smc_coherence[_block]() for ppc32  
3142 5857 d 1 h svoboda /trunk/kernel/generic/src/mm/ Fix build when smc_coherence_block() is defined as an empty macro  
3141 5857 d 4 h jermar /trunk/kernel/generic/src/mm/ Maintain cache coherence when the ELF backend duplicates a frame from an
executable segment.		  
3137 5857 d 5 h jermar /trunk/kernel/generic/src/proc/ Maintain cache coherence after sys_task_spawn() copies ELF image from user space.  
3130 5859 d 9 h jermar /trunk/kernel/generic/src/mm/ Add a comment explaining the reason for a memory barrier after page table update in detail.  
3128 5859 d 22 h jermar /trunk/kernel/generic/src/mm/ Issue a memory barrier after modifying a page table mapping in order to
prevent memory prefetching.		  
3113 5864 d 18 h decky /trunk/kernel/generic/ rename SYS_IO to SYS_KLOG
do not notify uspace klog with every single character, introduce some latency		  
3104 5865 d 9 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3097 5866 d 22 h decky /trunk/kernel/ resurrect klog  
3096 5866 d 22 h svoboda /trunk/kernel/generic/src/syscall/ Fix malloc(0) in sys_io()  
3090 5868 d 2 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3065 5868 d 2 h decky /trunk/kernel/generic/src/console/ remove original klog
permanent kernel cyclic log buffer
proper printf formatting		  
3064 5868 d 2 h decky /trunk/kernel/generic/src/syscall/ change SYS_IO semantics
add SYS_TASK_SPAWN
proper printf formatting		  
3063 5868 d 2 h decky /trunk/kernel/generic/src/proc/ support for SYS_SPAWN syscall
proper printf formatting
change the way init tasks are created		  
3062 5868 d 2 h decky /trunk/kernel/generic/src/proc/ proper printf formatting  
3061 5868 d 2 h decky /trunk/kernel/generic/src/main/ debugging output of kernel initialization  
3060 5868 d 2 h decky /trunk/kernel/generic/src/main/ run init tasks after they are all loaded  
3059 5868 d 2 h decky /trunk/kernel/generic/src/ proper printf formatting  
3058 5868 d 2 h decky /trunk/kernel/generic/src/ proper printf formatting, remove non-standard 'z' modifier  
3057 5868 d 2 h decky /trunk/kernel/generic/src/mm/ proper printf formatting  
3056 5868 d 2 h decky /trunk/kernel/generic/src/ proper printf formatting & coding style  
3055 5868 d 2 h decky /trunk/kernel/generic/src/interrupt/ proper printf formatting  
3054 5868 d 2 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3029 5872 d 2 h decky /trunk/kernel/generic/ fix kernel ramdisk support  
3020 5873 d 20 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
3007 5875 d 22 h jermar /trunk/ Improve linking and loading of boot ELF images.

2934 5886 d 22 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2916 5889 d 22 h jermar /trunk/kernel/generic/src/ More formatting changes.  
2914 5889 d 22 h jermar /trunk/kernel/generic/src/synch/ Formatting improvements.
