2494 6220 d 1 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 6220 d 5 h jermar /trunk/kernel/generic/include/ipc/ Collapse IPC method numbers.  
2471 6244 d 2 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2106 6378 d 8 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 6382 d 9 h decky /trunk/kernel/ move ipc structures to ipc.h  
2098 6383 d 4 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2089 6384 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6395 d 1 h jermar /trunk/ (c) versus (C)  
2026 6431 d 22 h jermar /trunk/kernel/generic/include/ipc/ Improve comment.  
2025 6431 d 22 h jermar /trunk/ Coding style fixes.  
1941 6486 d 5 h decky /trunk/kernel/generic/include/ cleanup  
1933 6487 d 0 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6487 d 1 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 6488 d 1 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 6488 d 1 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 6491 d 1 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 6520 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1877 6525 d 12 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1787 6585 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6592 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1712 6610 d 2 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.  
1702 6613 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1693 6615 d 5 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1643 6619 d 11 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1625 6619 d 23 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6620 d 14 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 6620 d 23 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1582 6621 d 11 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1573 6622 d 4 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1568 6622 d 6 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1507 6624 d 8 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6624 d 9 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 6626 d 8 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1428 6629 d 23 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 6640 d 8 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1359 6641 d 4 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1342 6641 d 12 h jermar /kernel/trunk/generic/ Improve comments.  
1329 6643 d 4 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1284 6654 d 13 h palkovsky /kernel/trunk/generic/ Added commands for accessing ia32 portspace in irq top-half.  
1281 6655 d 0 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.
