4384 5528 d 1 h svoboda /trunk/kernel/generic/src/ Clean up various log messages, mostly udebug.  
4304 5554 d 7 h jermar /trunk/kernel/generic/src/ipc/ Allow IPC_M_DATA_WRITE to transfer zero data.  
4274 5559 d 1 h decky /trunk/kernel/generic/src/ fix compilation in non-SMP configurations  
4254 5566 d 0 h jermar /trunk/kernel/generic/src/ Address issues with IRQ notifications.  
4252 5566 d 3 h decky /trunk/kernel/ move event notification to the ipc directory (where it probably belogs to, side-by-side to IRQ notifications)
cleanup the notification code a little bit (there is probably no need to allocate two structured dynamically)		  
4248 5566 d 7 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 5580 d 1 h jermar /trunk/ Revive kernel notifications.  
4041 5596 d 6 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 5597 d 9 h decky /trunk/kernel/generic/src/ipc/ add TODO  
3964 5607 d 9 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3947 5610 d 5 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 5612 d 0 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3902 5616 d 7 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 5619 d 2 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3870 5620 d 10 h decky /trunk/kernel/generic/src/ add includes necessary for LOG macro  
3867 5621 d 9 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 5637 d 2 h jermar /trunk/ Introduce a new syscall: SYS_IPC_FORWARD_SLOW.  
3657 5693 d 10 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3620 5700 d 11 h svoboda /trunk/kernel/generic/ Move stuff related to kbox to a separate struct.  
3603 5702 d 0 h svoboda /trunk/ Stoppability sections must be much smaller (design error). Also fix deadlock in udebug_stop(). Fix pause functionality in tracer.  
3496 5732 d 2 h svoboda /trunk/kernel/generic/src/ipc/ Split and streamline kbox_thread_proc().  
3495 5732 d 2 h svoboda /trunk/kernel/generic/src/ipc/ Synchronize properly when detaching kbox from within.  
3494 5734 d 2 h svoboda /trunk/kernel/generic/src/ipc/ Fix panic when debugged task quits. Also fix memory leak when debugger disconnects first.  
3476 5759 d 4 h jermar /trunk/kernel/generic/src/ipc/ Add comments documenting our treatment of the task's active call counter.  
3449 5766 d 2 h jermar /trunk/kernel/generic/src/ipc/ Fix task active call accounting for IPC_M_HUNGUP calls.  
3445 5767 d 2 h jermar /trunk/kernel/ Rename ipc/ipc_kbox.c to ipc/kbox.c.  
3441 5767 d 9 h svoboda /trunk/kernel/generic/src/ Use LOG() instead of printf() for debug messages.  
3438 5767 d 10 h svoboda /trunk/ Merge syscall tracer (trace) and relevant part of udebug interface from tracing to trunk.  
3395 5775 d 3 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 5776 d 1 h jermar /trunk/kernel/generic/src/ipc/ cstyle for ipc.c  
3370 5788 d 1 h jermar /trunk/kernel/generic/ Synchronous IPC must be interruptible.  
3363 5791 d 4 h jermar /trunk/kernel/generic/src/ipc/ Demasquerade the caller phone during ipc_answer_n() rather than in
ipc_wait_for_call().		  
3362 5791 d 4 h jermar /trunk/kernel/generic/ Fix processing of answers to forwarded masqueraded calls.  
3332 5799 d 9 h jermar /trunk/kernel/generic/src/ipc/ Fix types when processing IPC_M_DATA_WRITE arguments.  
3186 5853 d 4 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 5854 d 7 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 5870 d 15 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3090 5873 d 7 h decky /trunk/kernel/generic/src/ipc/ revert coding style change  
3054 5873 d 8 h decky /trunk/kernel/generic/src/ipc/ proper printf formatting  
3020 5879 d 2 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.
