* pci-arbiter,rumpdisk: Lock all memory for swappingDamien Zammit2021-12-271-0/+9
| | | | | | | This locks all memory in bootstrap processes so that disk driver dependencies don't get swapped out. Message-Id: <20211226113857.150525-5-damien@zamaudio.com>
* pci-arbiter: Implement memory mapping over region filesJoan Lledó2021-12-255-12/+124
| | | | | | | | | | | | | | | | | | | * pci-arbiter/Makefile: * Add device_map.c to sources * pci-arbiter/device_map.c: * pci-arbiter/device_map.h: * New module for device mapping * Relies on libpciaccess mapping methods * pci-arbiter/func_files.c: * io_region_file(): Use the new device mapping module * pci-arbiter/netfs_impl.c: * Implements netfs_get_filemap(): * Uses the device mapping module to map the region to the arbiter space * Calls the kernel RPC vm_region_create_proxy() to obtain the memory object proxy * Only region files are mapped for now Message-Id: <20211219112647.11512-4-jlledom@mailfence.com>
* pci-arbiter, rumpdisk: Rename options for bootstrap chainSamuel Thibault2021-08-114-18/+18
| | | | | | | | We may end up with an arbitrary series of bootstrap translators, which can know about each other through devices, and thus do not need any particular order except dependencies. The actual bootstrap order can thus be arbitrary (provided it respects dependencies), so better not hardcode it.
* libmachdev: Fix startup_dosyncSamuel Thibault2021-08-111-12/+1
| | | | | | | We do not actually want to shut everything down. For instance, we still have to be able to start the acpi translator to perform the actual shutdown. What we however have to do is syncing the disks.
* pci-arbiter: do not install as translator for nowSamuel Thibault2021-08-111-1/+1
| | | | | | machdev installs the trivfs translator, not the netfs translator, and thus pci-arbiter would only show up as the pci device, not the pci filesystem.
* pci-arbiter: Use _SERVERS_BUS macroSamuel Thibault2021-08-111-1/+1
|
* libmachdev: Restore making machdev_trivfs_server blockingSamuel Thibault2021-04-151-2/+11
| | | | | | | | | | | | | | | netdde actually needs to control which thread runs the trivfs server, for managing per-thread state etc. Only pci-arbiter needs to run machdev_trivfs_server non-blockingly, it can create a thread by itself. * libmachdev/trivfs_server.c (machdev_trivfs_loop): Move back muxer loop to... (machdev_trivfs_server): ... here. * pci-arbiter/main.c (main): Run machdev_trivfs_server in its own thread. * rumpdisk/main.c (main): Do not call pthread_exit().
* pci-arbiter: Fix --device-master-port option nameSamuel Thibault2021-04-051-1/+1
| | | | | | | for coherency with ext2fs and rumpdisk * pci-arbiter/options.h (options): Rename --dev-master-port option to --device-master-port option.
* pci-arbiter: restore code that allows it to run non-bootstrapSamuel Thibault2021-04-043-10/+21
| | | | | | | | | | * pci-arbiter/pcifs.h (init_root_node): Restore underlying_node parameter. * pci-arbiter/pcifs.c (underlying_stat): Drop global variable. (init_root_node): Restore getting the stat from the underlying node. * pci-arbiter/main.c (main): Restore calling netfs_startup in non-bootstrap case, and pass underlying node to init_root_node. Only call pcifs_startup in bootstrap case.
* machdev: Pass argv through to _hurd_initDamien Zammit2021-04-041-1/+1

* machdev,rump,pci: Rework bootstrapDamien Zammit2021-03-164-113/+9
| | | | | | | | | | | | | | | | | | | | | | | | | * libmachdev/trivfs_server.c (bootstrapped): Rename to bootstrapping. (trivfs_S_fsys_startup): Call fsys_startup on the bootstrap port. (essential_task): New function. (trivfs_S_fsys_init): Call fsys_init on the bootstrap port. Configure proc. Mark us as essential when bootstrapping even without a devnode. (arrange_shutdown_notification): Do not configure proc. (machdev_trivfs_init): Always get the bootstrap port from the kernel, leave it MACH_PORT_NULL if unavailable. Call fsys_getpriv on it if it is. * pci-arbiter/Makefile (SRCS): Remove startup.c. * pci-arbiter/startup.c: Delete file. * pci-arbiter/startup.h: Delete file. * pci-arbiter/main.c: Do not include "startup.h" (pci_device_shutdown): Do not try to lokup the dosync_handle. (pcifs_startup): Always create the pci_control_port right on the control port. (main): Call machdev_device_init after machdev_trivfs_init. Do not call arrange_shutdown_notification. * rumpdisk/main.c (netfs_server_name): Don't pretend to be the arbiter anymore (main): Call machdev_device_init after machdev_trivfs_init.

* pci-arbiter: Accept not having an underlying node.Damien Zammit2021-03-071-6/+12
| | | | | | * pci-arbiter/pcifs.c (underlying_stat): New variable. (init_file_system): When underlying_node is nul, use the underlying_stat content.

| | | | * pci-arbiter/pci-ops.c: Fix typo in comment.
* pci-arbiter: Probe devices and map regionsJoan Lledó2020-09-132-9/+30
| | | | | | | | | | | This adapts the arbiter to a bug fixed in libpciaccess. We were relying on the library to probe devices and map regions but it's the arbiter who should do it. * pci-arbiter/pcifs.c: * create_fs_tree(): probe the device to find regions and rom * pci-arbiter/func_files.c: * io_region_file(): map region on the first access attempt
