4670 5628 d 17 h jermar /trunk/kernel/generic/src/ipc/ Interrupts should be disabled when acquiring answerbox's irq_lock.  
4490 5683 d 11 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4460 5683 d 12 h jermar /trunk/kernel/generic/src/ipc/ Streamline locking of phones during cloning.  
4430 5694 d 21 h jermar /trunk/kernel/generic/src/ipc/ Surprisingly easy support for homogenous mounts.
It works by simply allowing autoconnections.
 
4422 5696 d 13 h jermar /trunk/kernel/generic/src/ipc/ Refuse to clone the phone which is itself used to make the IPC_M_CONNECTION_CLONE call.  
4407 5698 d 9 h jermar /trunk/ Add IPC_M_CONNECTION_CLONE and IPC_M_CONNECT_ME.  
4405 5698 d 9 h jermar /trunk/kernel/generic/src/ipc/ Do not test the same condition twice.  
4384 5703 d 9 h svoboda /trunk/kernel/generic/src/ Clean up various log messages, mostly udebug.  
4304 5729 d 15 h jermar /trunk/kernel/generic/src/ipc/ Allow IPC_M_DATA_WRITE to transfer zero data.  
4274 5734 d 9 h decky /trunk/kernel/generic/src/ fix compilation in non-SMP configurations  
4254 5741 d 8 h jermar /trunk/kernel/generic/src/ Address issues with IRQ notifications.  
4252 5741 d 11 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 5741 d 15 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 5755 d 9 h jermar /trunk/ Revive kernel notifications.  
4041 5771 d 14 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 5772 d 17 h decky /trunk/kernel/generic/src/ipc/ add TODO  
3964 5782 d 17 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3947 5785 d 13 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 5787 d 8 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3902 5791 d 15 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.
