3870 5650 d 13 h decky /trunk/kernel/generic/src/ add includes necessary for LOG macro  
3867 5651 d 12 h svoboda /trunk/kernel/generic/src/ipc/ Bugfix: Check kbox, not regular box. In case where the debugger disconnected first and then the application terminated, the application task would not be cleaned up.  
3819 5667 d 5 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3657 5723 d 13 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3620 5730 d 15 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3603 5732 d 3 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3496 5762 d 5 h svoboda /trunk/kernel/generic/src/ipc/ Split and streamline kbox_thread_proc().  
3495 5762 d 6 h svoboda /trunk/kernel/generic/src/ipc/ Synchronize properly when detaching kbox from within.  
3494 5764 d 5 h svoboda /trunk/kernel/generic/src/ipc/ Fix panic when debugged task quits. Also fix memory leak when debugger disconnects first.  
3476 5789 d 7 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3449 5796 d 5 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5797 d 5 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3441 5797 d 12 h svoboda /trunk/kernel/generic/src/ Use LOG() instead of printf() for debug messages.  
3438 5797 d 13 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5805 d 6 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 5806 d 4 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5818 d 4 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5821 d 7 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().
 
3362 5821 d 7 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3332 5829 d 12 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3186 5883 d 7 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.
 
3184 5884 d 10 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.
 
3104 5900 d 18 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5903 d 10 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5903 d 11 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5909 d 5 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2934 5922 d 7 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2802 5962 d 14 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.
 
2745 6000 d 14 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2677 6058 d 9 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.
 
2676 6058 d 15 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
 
2662 6066 d 4 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2661 6066 d 5 h jermar /trunk/kernel/generic/src/ipc/ Release the IPC_M_DATA_WRITE buffer even if the write is refused by the
recipient.
 
2660 6066 d 6 h jermar /trunk/ Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().
 
2638 6085 d 5 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6085 d 6 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2636 6087 d 4 h jermar /trunk/ Update comments wrt the previous commit.
Minor formatting fixes.
 
2635 6087 d 6 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.
 
2626 6094 d 15 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2623 6095 d 11 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.
