3478 5787 d 3 h decky /branches/arm/ new arm branch  
3476 5788 d 20 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3468 5790 d 6 h svoboda /trunk/kernel/generic/src/udebug/ Document functions in udebug_ipc.c  
3457 5794 d 19 h svoboda /trunk/kernel/generic/src/udebug/ Document functions in udebug.c and udebug_ops.c  
3451 5795 d 17 h jermar /trunk/kernel/generic/src/console/ Rename kconsole's 'ipc_task' command to 'ipc'.  
3449 5795 d 18 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5796 d 18 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3441 5797 d 1 h svoboda /trunk/kernel/generic/src/ Use LOG() instead of printf() for debug messages.  
3438 5797 d 2 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3422 5799 d 17 h jermar /trunk/kernel/generic/src/mm/ as_area_resize() should use as instead of AS.  
3404 5800 d 3 h jermar /trunk/kernel/generic/src/lib/ cstyle  
3395 5804 d 19 h jermar /trunk/kernel/generic/ Kernel's ipc_data_t and uspace's ipc_call_t must be in sync.

This commit fixes a problem introduced in revision 3362, when
ipc_data_t was enlarged by the caller_phone member. This resulted
in sys_ipc_wait_for_call() passing larger structure to uspace
than requested, leading to a random damage of userspace memory.
 
3394 5805 d 17 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3384 5811 d 19 h jermar /trunk/kernel/generic/src/mm/ cstyle  
3383 5812 d 5 h svoboda /trunk/kernel/generic/src/mm/ Fix panic caused by not setting new area flags in as_area_change_flags(), as pointed out by Jakub.  
3382 5812 d 17 h jermar /trunk/kernel/generic/src/mm/ Fix the rare case when the anon or ELF backend uses PFN 0 for mapping.  
3370 5817 d 17 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5820 d 20 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().
 
3362 5820 d 20 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3359 5821 d 4 h jermar /trunk/kernel/generic/src/proc/ Improve comments in task.c  
3332 5829 d 1 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3274 5834 d 23 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
3246 5838 d 20 h jermar /trunk/ cstyle  
3240 5845 d 4 h decky / move unfinished ObjC support to a separate branch  
3225 5851 d 4 h jermar /trunk/kernel/generic/src/sysinfo/ Check the validity of the 'len' argument for sysinfo syscalls.  
3222 5867 d 22 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3208 5869 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 5869 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 5869 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 5869 d 22 h jermar /trunk/kernel/generic/src/mm/ Fix deadlock in the 'zones' kconsole command.  
3194 5875 d 3 h jermar /trunk/kernel/generic/src/console/ Remove left-over debugging stuff.  
3193 5875 d 18 h jermar /trunk/kernel/ cstyle fixes  
3188 5882 d 15 h jermar /trunk/kernel/generic/src/mm/ Finer grained waiting for memory with consideration of the number
of available memory frames.
 
3187 5882 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 5882 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 5883 d 19 h jermar /trunk/kernel/generic/src/mm/ cstyle for frame.c  
3184 5883 d 22 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 5884 d 0 h jermar /trunk/kernel/generic/src/mm/ Avoid easy deadlock while printing slab cache statistics.  
3181 5885 d 3 h jermar /trunk/kernel/generic/src/ cstyle for kinit.c and scheduler.c  
3180 5885 d 5 h jermar /trunk/kernel/generic/src/mm/ cstyle for slab.c
