2662 5988 d 6 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2661 5988 d 7 h jermar /trunk/kernel/generic/src/ipc/ Release the IPC_M_DATA_WRITE buffer even if the write is refused by the
recipient.		  
2660 5988 d 8 h jermar /trunk/ Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().		  
2647 5995 d 9 h jermar /trunk/kernel/generic/src/mm/ Fix a bug in anonymous address space area sharing. Call the backend's share
function only if the source area is not already shared. Otherwise increment the
sh_info refcount. Without this fix, the kernel will try to recreate the pagemap
if three and more address space areas attempt to share the same data.		  
2646 5995 d 9 h jermar /trunk/kernel/generic/include/ Formatting.  
2638 6007 d 7 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6007 d 7 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2636 6009 d 6 h jermar /trunk/ Update comments wrt the previous commit.
Minor formatting fixes.		  
2635 6009 d 7 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.		  
2634 6010 d 2 h decky /trunk/kernel/arch/mips32/src/ fix trivial bug in storing lastcount  
2633 6010 d 2 h decky /trunk/kernel/arch/mips32/ CPU cycle accounting on MIPS  
2632 6010 d 3 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2630 6015 d 5 h jermar /trunk/kernel/arch/ Formatting fixes.  
2626 6016 d 17 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2623 6017 d 13 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6017 d 13 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2620 6019 d 18 h jermar /trunk/ Be more deterministic when a user accidently uses fast version of IPC
call/answer instead of the full one and passes fewer arguments than required by
the recipient of the call/response.

and the recipient interprets arguments that
were actually not passed by the sender.		  
2619 6021 d 6 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().		  
2618 6021 d 18 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.		  
2617 6022 d 11 h jermar /trunk/kernel/generic/src/ipc/ STRUCT_TO_USPACE may fail in sys_ipc_call_sync_fast.
