3819 5605 d 2 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3761 5631 d 2 h decky /trunk/ send notification to uspace console when switching from kernel console  
3620 5668 d 11 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3446 5734 d 15 h svoboda /trunk/kernel/generic/include/ipc/ Fix: Rename ipc_kbox.h to kbox.h  
3438 5735 d 10 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5743 d 3 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.		  
3370 5756 d 1 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3362 5759 d 4 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3020 5847 d 1 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2802 5900 d 11 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2677 5996 d 5 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 5996 d 12 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 6004 d 1 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2660 6004 d 2 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 6023 d 2 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6023 d 2 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2635 6025 d 2 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 6032 d 12 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2623 6033 d 8 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6033 d 8 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2619 6037 d 0 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2618 6037 d 13 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.		  
2615 6038 d 10 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.		  
2614 6039 d 7 h jermar /trunk/kernel/generic/include/ipc/ Grow the IPC data structures from 3 to 5 payload arguments.
No IPC API changes so far.		  
2550 6090 d 5 h cejka /trunk/ Fixed naming convention in IPC.  
2527 6102 d 11 h jermar /trunk/ VFS work.

Added mandatory VFS_LOOKUP

Handling of VFS_REGISTER request should be now more or less complete.
Added code that inserts the new fs_info structure into the list of registered
filesystems and creates a callback connection to the client FS.		  
2523 6103 d 13 h jermar /trunk/ VFS work.

Now, each VFS connection fibril will accept requests in a loop. The idea is that
each connection will be potentially reused for multiple requests before it is
closed by the server.

More VFS_REGISTER bits. Make use of the IPC_M_DATA_SEND wrappers introduced in
the previous commit.

Add enum members for more VFS operations.		  
2494 6169 d 2 h jermar /trunk/kernel/generic/ Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another.		  
2493 6169 d 6 h jermar /trunk/kernel/generic/include/ipc/ Collapse IPC method numbers.  
2471 6193 d 2 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2106 6327 d 9 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.		  
2105 6331 d 9 h decky /trunk/kernel/ move ipc structures to ipc.h  
2098 6332 d 4 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2089 6333 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6344 d 1 h jermar /trunk/ (c) versus (C)  
2026 6380 d 23 h jermar /trunk/kernel/generic/include/ipc/ Improve comment.  
2025 6380 d 23 h jermar /trunk/ Coding style fixes.  
1941 6435 d 5 h decky /trunk/kernel/generic/include/ cleanup  
1933 6436 d 1 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6436 d 2 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.
