4248 5617 d 2 h decky /trunk/kernel/generic/src/ipc/ avoid deadlock during cleanup
(the compare function which is called inside hash_table_remove acquires irq->lock)		  
4173 5630 d 20 h jermar /trunk/ Revive kernel notifications.  
4041 5647 d 2 h jermar /trunk/kernel/generic/ If the server cannot receive a call because it supplied a bad userspace address, the kernel will immediately answer the call with EPARTY.  
4040 5648 d 4 h decky /trunk/kernel/generic/src/ipc/ add TODO  
3964 5658 d 4 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3947 5661 d 0 h jermar /trunk/ This is the evil commit. In particular, it does:

- introduces more powerful pseudo code for userspace IRQ top-half handlers
- changes the internals of IRQ dispatching
- simplifies the kernel's i8042 driver
- adapts the uspace i8042 driver to make use of the new pseudocode
- breaks all other architectures except ia32
- breaks almost all existing drivers
- breaks switching between uspace and kernel drivers		  
3930 5662 d 20 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3902 5667 d 2 h jermar /trunk/kernel/ Introduce a more platform-neutral name for programmed I/O.

The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers.		  
3875 5669 d 22 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3870 5671 d 5 h decky /trunk/kernel/generic/src/ add includes necessary for LOG macro  
3867 5672 d 4 h svoboda /trunk/kernel/generic/src/ipc/ Bugfix: Check kbox, not regular box. In case where the debugger disconnected first and then the application terminated, the application task would not be cleaned up.  
3819 5687 d 21 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3657 5744 d 5 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3620 5751 d 7 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3603 5752 d 19 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3496 5782 d 21 h svoboda /trunk/kernel/generic/src/ipc/ Split and streamline kbox_thread_proc().  
3495 5782 d 22 h svoboda /trunk/kernel/generic/src/ipc/ Synchronize properly when detaching kbox from within.  
3494 5784 d 21 h svoboda /trunk/kernel/generic/src/ipc/ Fix panic when debugged task quits. Also fix memory leak when debugger disconnects first.  
3476 5809 d 23 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3449 5816 d 21 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5817 d 21 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3441 5818 d 4 h svoboda /trunk/kernel/generic/src/ Use LOG() instead of printf() for debug messages.  
3438 5818 d 5 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5825 d 22 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.		  
3394 5826 d 20 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5838 d 21 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5841 d 23 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().		  
3362 5841 d 23 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3332 5850 d 4 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3186 5903 d 23 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.		  
3184 5905 d 2 h jermar /trunk/kernel/generic/src/ipc/ Fix a scary two-year old bug: do not attempt to initialize a call structure if
its allocation failed.		  
3104 5921 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5924 d 2 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5924 d 3 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5929 d 21 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2934 5942 d 23 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2802 5983 d 6 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2745 6021 d 6 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2677 6079 d 1 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 6079 d 7 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.
