Currently, the port names are mapped to an IPC object (e.g. a port)
using a table. This, however, requires large chunks of continuous
memory, and leads to scalability problems as virtual kernel memory is
a scarce resource. To avoid excessive overhead, non-contiguous port
names are spilled into a splay tree.
Replace the IPC table with a radix tree. As the radix tree is able to
store non-contiguous names with reasonable overhead, we can drop the
splay tree as well.

Retire the compatibility RPC `old_mach_port_get_receive_status' that
works like `mach_port_get_receive_status' but returns an
`old_mach_port_status' object that lacks the `mps_seqno' field.
Do not remove the type yet, so we do not break anyones build. The RPC
stubs currently distributed with the glibc require it.

In order to use MIG translation functions to lookup memory objects,
preprocessor macros have been introduced into the definition of
memory_object_t in 50cc5152.
The procedure definitions contain inlined type definitions in order to
change the type of the argument in question (i.e. to make it
polymorphic). The inline definitions however lack the destructor
function, leading to reference leaks when a reference is acquired in
the intran function.
* include/mach/memory_object.defs: Add the destructor functions to the
inlined type definitions.
|

Previously, the definition of the host_slab_info RPC was guarded with
MACH_VM_DEBUG, even though it is not at all concerned with the VM
subsystem. Furthermore, there was no "skip" directive for
host_slab_info.
The function host_slab_info is guarded with MACH_DEBUG. The server
for the RPCs in mach_debug.defs is only used if MACH_DEBUG is
defined. There is no need to guard host_slab_info.
* include/mach_debug/mach_debug.defs (host_slab_info): Unconditionally
include the RPC.
|
|
Previously, every userspace server implementing the device protocol
filtered the device definitions to replace the device_t type with
mach_port_send_t to make the device argument of device_open
polymorphic. Rather than doing that, which makes it impossible to use
translation functions, fix the definition of device_open.
* include/device/device.defs (device_open): Redefine the device
argument to make it polymorphic unless a outran function is specified.
