* Add hardware interrupt notification mechanismSamuel Thibault2020-07-1018-81/+776
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows privileged userland drivers to get notifications of hardware interrupts. Initial work by Zheng Da, reworked by Damien Zammit and myself. * Makefrag.am (libkernel_a_SOURCES): Add device/intr.c and device/intr.h. (include_device_HEADERS): Add include/device/notify.defs and include/device/notify.h. * device/dev_hdr.h (name_equal): Add declaration. * device/ds_routines.c: Include <device/intr.h> (ds_device_intr_register, ds_device_intr_ack): New functions. * device/intr.c, device/intr.h: New files. * doc/mach.texi (Device Interrupt): New section. * i386/Makefrag.am (libkernel_a_SOURCES): Add i386/i386/irq.c and i386/i386/irq.h. * i386/i386/irq.c, i386/i386/irq.h: New files. * i386/i386at/conf.c: Include <device/intr.h>.

(install_user_intr_handler): New function. (request_irq): Initialize user_intr field. * linux/src/include/asm-i386/irq.h (__disable_irq, __enable_irq): Remove prototypes. * i386/i386/pic.c (mask_irq, unmask_irq): New functions. * i386/i386/pic.h (mask_irq, unmask_irq): New prototypes.
* Add vm_allocate_contiguous RPCSamuel Thibault2020-07-095-0/+184
| | | | | | | | | | | | | | | | | 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.

* Add experimental RPC infrastructureSamuel Thibault2020-07-094-0/+27
| | | | | | | | | | | | | | | | 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.

(ipc_kobject_server): Call experimental_server_routine.
* vm_map: Allow passing the name of a memory objectSamuel Thibault2020-06-201-2/+4
| | | | | | | as is returned by vm_info. * vm/vm_user.c (vm_map): Before trying to vm_object_enter, try to simply lookup the name.

| | | | Based on UEFI 2.8A spec
* kmem_alloc_wired: factorize with kmem_vallocSamuel Thibault2020-05-011-49/+3
| | | | * vm/vm_kern.c (kmem_alloc_wired): Factorize with kmem_valloc.
* Add kmem_vallocSamuel Thibault2020-05-013-1/+80
| | | | | | | | | | | 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.

* bootstrap: Add missing reference to send port between tasksSamuel Thibault2020-04-061-1/+2
| | | | | | | | | 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.
