* memory_object: Fix memory_object_t type in the kernelSamuel Thibault2021-11-071-2/+6
| | | | | | | | | | mach_port_t is for userland, kernel sees the translated ipc_port_t. * include/mach/memory_object.h [MACH_KERNEL]: Include ipc/ipc_types.h [MACH_KERNEL] (memory_object_t): Typedef to ipc_port_t instead of mach_port_t.

* device_read: Add dealloc for dataSamuel Thibault2021-08-211-1/+1
| | | | | | | | | It would be very tricky for the server to manage deallocation for device_read, and does not seem useful anyway. device_reply.defs already has it. * include/device/device.defs (device_read): Add dealloc flag for the data array.

* Add vm_allocate_contiguous RPCSamuel Thibault2020-07-091-0/+24
| | | | | | | | | | | | | | | | | This allows privileged userland drivers to allocate buffers for e.g. DMA, and thus need them to be physically contiguous and get their physical address.

* ipc: replace the IPC table with a radix treeJustus Winter2015-05-203-48/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * ipc/ipc_entry.c (ipc_entry_tree_collision): Remove function.
