2647 6004 d 22 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 6004 d 22 h jermar /trunk/kernel/generic/include/ Formatting.  
2638 6016 d 20 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6016 d 21 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2636 6018 d 19 h jermar /trunk/ Update comments wrt the previous commit.
Minor formatting fixes.		  
2635 6018 d 21 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.		  
2632 6019 d 16 h decky /trunk/kernel/generic/src/proc/ try to kill the tasks fewer times by introducing a delay in iterations  
2626 6026 d 7 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2623 6027 d 2 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6027 d 2 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2620 6029 d 7 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 6030 d 19 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 6031 d 7 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 6032 d 0 h jermar /trunk/kernel/generic/src/ipc/ STRUCT_TO_USPACE may fail in sys_ipc_call_sync_fast.  
2615 6032 d 4 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.		  
2614 6033 d 2 h jermar /trunk/kernel/generic/include/ipc/ Grow the IPC data structures from 3 to 5 payload arguments.
No IPC API changes so far.		  
2605 6035 d 0 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.		  
2601 6039 d 23 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2574 6055 d 21 h jermar /trunk/kernel/generic/src/lib/ Fix elf.c's formatting and add code that can be later enhanced and used to
remember task's TLS section alignment, address and size.		  
2573 6058 d 22 h jermar /trunk/kernel/generic/include/lib/ Add SHF_TLS ELF section header flag.
This will be needed for detecting alignment of TLS sections of userspace tasks
loaded at runtime.
