2614 6083 d 2 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 6134 d 0 h cejka /trunk/ Fixed naming convention in IPC.  
2527 6146 d 6 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 6147 d 8 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 6212 d 21 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 6213 d 1 h jermar /trunk/kernel/generic/include/ipc/ Collapse IPC method numbers.  
2471 6236 d 21 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2106 6371 d 4 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 6375 d 4 h decky /trunk/kernel/ move ipc structures to ipc.h  
2098 6375 d 23 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2089 6377 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6387 d 20 h jermar /trunk/ (c) versus (C)  
2026 6424 d 18 h jermar /trunk/kernel/generic/include/ipc/ Improve comment.  
2025 6424 d 18 h jermar /trunk/ Coding style fixes.  
1941 6479 d 0 h decky /trunk/kernel/generic/include/ cleanup  
1933 6479 d 20 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6479 d 21 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 6480 d 20 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 6480 d 20 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 6483 d 20 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 6513 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1877 6518 d 8 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1787 6577 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6585 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1712 6602 d 22 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.  
1702 6606 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1693 6608 d 0 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1643 6612 d 6 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1625 6612 d 18 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6613 d 9 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.		  
1591 6613 d 19 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1582 6614 d 6 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1573 6615 d 0 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1568 6615 d 1 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1507 6617 d 3 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6617 d 5 h jermar /kernel/trunk/ Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.
O		  
1461 6619 d 3 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1428 6622 d 18 h palkovsky /kernel/trunk/generic/ Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA.		  
1364 6633 d 3 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1359 6634 d 0 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.
