2020-07-09Add vm_allocate_contiguous RPCSamuel Thibault
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. Initial work by Zheng Da, reworked by Richard Braun, Damien Zammit, and myself. * doc/mach.texi (vm_allocate_contiguous): New RPC. * i386/include/mach/i386/machine_types.defs (rpc_phys_addr_t): New type. * i386/include/mach/i386/vm_types.h [!MACH_KERNEL] (phys_addr_t): Set type to 64bits. (rpc_phys_addr_t): New type, always 64bits. * include/mach/gnumach.defs (vm_allocate_contiguous):New RPC. * vm/vm_user.c (vm_allocate_contiguous): New function.
2020-07-09Add experimental RPC infrastructureSamuel Thibault
This is free for experimenting RPCs, with no backward compatibility guarantees. * Makefrag.am (EXTRA_DIST): Add kern/experimental.srv. (include_mach_HEADERS): Add include/mach/experimental.defs. (nodist_lib_dep_tr_for_defs_a_SOURCES): Add kern/experimental.server.defs.c. (nodist_libkernel_a_SOURCES): Add kern/experimental.server.h, kern/experimental.server.c, kern/experimental.server.msgids. (nodist_libkernel_a_SOURCES): Add kern/experimental.server.defs. * include/mach/experimental.defs: New file. * kern/experimental.srv: New file. * kern/ipc_kobject.c: Include <kern/experimental.server.h>. (ipc_kobject_server): Call experimental_server_routine.

2020-07-05Making vm_allocate_contiguous return a memory object is not really a prioritySamuel Thibault

2020-05-01kmem_alloc_wired: factorize with kmem_vallocSamuel Thibault
* vm/vm_kern.c (kmem_alloc_wired): Factorize with kmem_valloc.
2020-05-01Add kmem_vallocSamuel Thibault
Functions like vremap need to allocate some virtual addressing space before making their own mapping. kmem_alloc_wired can be used for that but that wastes memory. * vm/vm_kern.c (kmem_valloc): New function. * vm/vm_kern.h (kmem_valloc): New prototype. * linux/dev/glue/kmem.c (vremap): Call kmem_valloc instead of kmem_alloc_wired. Also check that `offset' is aligned on a page.

2020-04-06bootstrap: Add missing reference to send port between tasksSamuel Thibault
When giving the port to a bootstrap task to another bootstrap task, we need to add a reference. This shows up on error-cleanup (e.g. when forgetting to define the root). * kern/bootstrap.c (boot_script_insert_task_port): Call ipc_port_make_send on `task''s itk_sself.

2020-03-31Restore vm_size_t to natural_tSamuel Thibault
Plenty of places such as glibc RPC uses currently assume that vm_size_t is a natural_t (thus int on 32bit), not an unsigned long. * i386/include/mach/i386/vm_types.h (vm_size_t) [!__x86_64__]: Set type to natural_t. * device/dev_page.c (device_pager_data_request): Cast vm_size_t to unsigned long. * i386/i386at/model_dep.c (c_boot_entry): Likewise.

2020-03-29Share ncom, lpr, PAE definitions between i386 and x86_64Samuel Thibault
