2614 6032 d 6 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 6083 d 4 h cejka /trunk/ Fixed naming convention in IPC.  
2527 6095 d 9 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 6096 d 12 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 6162 d 0 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 6162 d 4 h jermar /trunk/kernel/generic/include/ipc/ Collapse IPC method numbers.  
2471 6186 d 1 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2106 6320 d 7 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 6324 d 8 h decky /trunk/kernel/ move ipc structures to ipc.h  
2098 6325 d 2 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2089 6326 d 7 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6337 d 0 h jermar /trunk/ (c) versus (C)  
2026 6373 d 21 h jermar /trunk/kernel/generic/include/ipc/ Improve comment.  
2025 6373 d 21 h jermar /trunk/ Coding style fixes.  
1941 6428 d 3 h decky /trunk/kernel/generic/include/ cleanup  
1933 6428 d 23 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6429 d 0 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 6429 d 23 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 6430 d 0 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 6433 d 0 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.
