2660 6038 d 7 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 6057 d 7 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6057 d 7 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2635 6059 d 7 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 6066 d 17 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2623 6067 d 13 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6067 d 13 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2619 6071 d 6 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 6071 d 18 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 6072 d 15 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 6073 d 13 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 6124 d 10 h cejka /trunk/ Fixed naming convention in IPC.  
2527 6136 d 16 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 6137 d 18 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 6203 d 7 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 6203 d 11 h jermar /trunk/kernel/generic/include/ipc/ Collapse IPC method numbers.  
2471 6227 d 8 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2106 6361 d 14 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 6365 d 14 h decky /trunk/kernel/ move ipc structures to ipc.h  
2098 6366 d 9 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2089 6367 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6378 d 7 h jermar /trunk/ (c) versus (C)  
2026 6415 d 4 h jermar /trunk/kernel/generic/include/ipc/ Improve comment.  
2025 6415 d 4 h jermar /trunk/ Coding style fixes.  
1941 6469 d 10 h decky /trunk/kernel/generic/include/ cleanup  
1933 6470 d 6 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6470 d 7 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.		  
1924 6471 d 6 h jermar /trunk/kernel/generic/ For the sake of clarity, get rid of negative INR for virtual interrupts.
This way, the code can hurt performance on systems where the non-negative klog INR overlaps
with a frequently used INR such as system clock on amd64 and ia32.		  
1923 6471 d 6 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.		  
1919 6474 d 6 h jermar /trunk/kernel/ Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only.		  
1888 6503 d 10 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1877 6508 d 18 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1787 6568 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6575 d 10 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1712 6593 d 8 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.  
1702 6596 d 13 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1693 6598 d 10 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1643 6602 d 16 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1625 6603 d 4 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6603 d 19 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
