4173 5602 d 6 h jermar /trunk/ Revive kernel notifications.  
4041 5618 d 11 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 5619 d 14 h decky /trunk/kernel/generic/src/ipc/ add TODO  
3964 5629 d 14 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3947 5632 d 10 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 5634 d 5 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3902 5638 d 12 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 5641 d 7 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3870 5642 d 15 h decky /trunk/kernel/generic/src/ add includes necessary for LOG macro  
3867 5643 d 14 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 5659 d 7 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3657 5715 d 15 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3620 5722 d 16 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3603 5724 d 5 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3496 5754 d 7 h svoboda /trunk/kernel/generic/src/ipc/ Split and streamline kbox_thread_proc().  
3495 5754 d 7 h svoboda /trunk/kernel/generic/src/ipc/ Synchronize properly when detaching kbox from within.  
3494 5756 d 7 h svoboda /trunk/kernel/generic/src/ipc/ Fix panic when debugged task quits. Also fix memory leak when debugger disconnects first.  
3476 5781 d 9 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3449 5788 d 7 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5789 d 7 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3441 5789 d 14 h svoboda /trunk/kernel/generic/src/ Use LOG() instead of printf() for debug messages.  
3438 5789 d 15 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5797 d 8 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 5798 d 6 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5810 d 6 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5813 d 9 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().		  
3362 5813 d 9 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3332 5821 d 14 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3186 5875 d 9 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 5876 d 12 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 5892 d 20 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5895 d 12 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5895 d 13 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5901 d 7 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2934 5914 d 9 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2802 5954 d 16 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2745 5992 d 16 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2677 6050 d 11 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 6050 d 17 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.		  
2662 6058 d 6 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.
