Replay r349335 by scottl accidentally reverted by r349352 Add the PCI HDAudio device model from the 2016 GSoC. Detailed information can be found at https://wiki.freebsd.org/SummerOfCode2016/HDAudioEmulationForBhyve This commit has evolved from the original work to include Capsicum integration. As part of that, it only opens the host audio devices once and leaves them open, instead of opening and closing them on each guest access.

Refactor configuration management in bhyve. Replace the existing ad-hoc configuration via various global variables with a small database of key-value pairs. The database supports heirarchical keys using a MIB-like syntax to name the path to a given key. Values are always stored as strings. The API used to manage configuation values does include wrappers to handling boolean values. Other values use non-string types require parsing by consumers. The configuration values are stored in a tree using nvlists. Leaf nodes hold string values. Configuration values are permitted to reference other configuration values using '%(name)'. This permits constructing template configurations. All existing command line arguments now set configuration values. For devices, the "-s" option parses its option argument to generate a list of key-value pairs for the given device. A new '-o' command line option permits setting an individual configuration variable. The key name is always given as a full path of dot-separated components. A new '-k' command line option parses a simple configuration file. This configuration file holds a flat list of 'key=value' lines where the 'key' is the full path of a configuration variable. Lines starting with a '#' are comments. In general, bhyve starts by parsing command line options in sequence and applying those settings to configuration values. Once this is complete, bhyve then begins initializing its state based on the configuration values. This means that subsequent configuration options or files may override or supplement previously given settings. A special 'config.dump' configuration value can be set to true to help debug configuration issues. When this value is set, bhyve will print out the configuration variables as a flat list of 'key=value' lines. Most command line argments map to a single configuration variable, e.g. '-w' sets the 'x86.strictmsr' value to false. A few command line arguments have less obvious effects: - Multiple '-p' options append their values (as a comma-seperated list) to "vcpu.N.cpuset" values (where N is a decimal vcpu number). - For '-s' options, a pci.<bus>.<slot>.<function> node is created. The first argument to '-s' (the device type) is used as the value of a "device" variable. Additional comma-separated arguments are then parsed into 'key=value' pairs and used to set additional variables under the device node. A PCI device emulation driver can provide its own hook to override the parsing of the additonal '-s' arguments after the device type. After the configuration phase as completed, the init_pci hook then walks the "pci.<bus>.<slot>.<func>" nodes. It uses the "device" value to find the device model to use. The device model's init routine is passed a reference to its nvlist node in the configuration tree which it can query for specific variables. The result is that a lot of the string parsing is removed from the device models and centralized. In addition, adding a new variable just requires teaching the model to look for the new variable. - For '-l' options, a similar model is used where the string is parsed into values that are later read during initialization. One key note here is that the serial ports use the commonly used lowercase names from existing documentation and examples (e.g. "lpc.com1") instead of the uppercase names previously used internally in bhyve.

Refactor configuration management in bhyve. Replace the existing ad-hoc configuration via various global variables with a small database of key-value pairs. The database supports heirarchical keys using a MIB-like syntax to name the path to a given key. Values are always stored as strings. The API used to manage configuation values does include wrappers to handling boolean values. Other values use non-string types require parsing by consumers. The configuration values are stored in a tree using nvlists. Leaf nodes hold string values. Configuration values are permitted to reference other configuration values using '%(name)'. This permits constructing template configurations. All existing command line arguments now set configuration values. For devices, the "-s" option parses its option argument to generate a list of key-value pairs for the given device. A new '-o' command line option permits setting an individual configuration variable. The key name is always given as a full path of dot-separated components. A new '-k' command line option parses a simple configuration file. This configuration file holds a flat list of 'key=value' lines where the 'key' is the full path of a configuration variable. Lines starting with a '#' are comments. In general, bhyve starts by parsing command line options in sequence and applying those settings to configuration values. Once this is complete, bhyve then begins initializing its state based on the configuration values. This means that subsequent configuration options or files may override or supplement previously given settings. A special 'config.dump' configuration value can be set to true to help debug configuration issues. When this value is set, bhyve will print out the configuration variables as a flat list of 'key=value' lines. Most command line argments map to a single configuration variable, e.g. '-w' sets the 'x86.strictmsr' value to false. A few command line arguments have less obvious effects: - Multiple '-p' options append their values (as a comma-seperated list) to "vcpu.N.cpuset" values (where N is a decimal vcpu number). - For '-s' options, a pci.<bus>.<slot>.<function> node is created. The first argument to '-s' (the device type) is used as the value of a "device" variable. Additional comma-separated arguments are then parsed into 'key=value' pairs and used to set additional variables under the device node. A PCI device emulation driver can provide its own hook to override the parsing of the additonal '-s' arguments after the device type. After the configuration phase as completed, the init_pci hook then walks the "pci.<bus>.<slot>.<func>" nodes. It uses the "device" value to find the device model to use. The device model's init routine is passed a reference to its nvlist node in the configuration tree which it can query for specific variables. The result is that a lot of the string parsing is removed from the device models and centralized. In addition, adding a new variable just requires teaching the model to look for the new variable. - For '-l' options, a similar model is used where the string is parsed into values that are later read during initialization. One key note here is that the serial ports use the commonly used lowercase names from existing documentation and examples (e.g. "lpc.com1") instead of the uppercase names previously used internally in bhyve.

Refactor configuration management in bhyve. Replace the existing ad-hoc configuration via various global variables with a small database of key-value pairs. The database supports heirarchical keys using a MIB-like syntax to name the path to a given key. Values are always stored as strings. The API used to manage configuation values does include wrappers to handling boolean values. Other values use non-string types require parsing by consumers. The configuration values are stored in a tree using nvlists. Leaf nodes hold string values. Configuration values are permitted to reference other configuration values using '%(name)'. This permits constructing template configurations. All existing command line arguments now set configuration values. For devices, the "-s" option parses its option argument to generate a list of key-value pairs for the given device. A new '-o' command line option permits setting an individual configuration variable. The key name is always given as a full path of dot-separated components. A new '-k' command line option parses a simple configuration file. This configuration file holds a flat list of 'key=value' lines where the 'key' is the full path of a configuration variable. Lines starting with a '#' are comments. In general, bhyve starts by parsing command line options in sequence and applying those settings to configuration values. Once this is complete, bhyve then begins initializing its state based on the configuration values. This means that subsequent configuration options or files may override or supplement previously given settings. A special 'config.dump' configuration value can be set to true to help debug configuration issues. When this value is set, bhyve will print out the configuration variables as a flat list of 'key=value' lines. Most command line argments map to a single configuration variable, e.g. '-w' sets the 'x86.strictmsr' value to false. A few command line arguments have less obvious effects: - Multiple '-p' options append their values (as a comma-seperated list) to "vcpu.N.cpuset" values (where N is a decimal vcpu number). - For '-s' options, a pci.<bus>.<slot>.<function> node is created. The first argument to '-s' (the device type) is used as the value of a "device" variable. Additional comma-separated arguments are then parsed into 'key=value' pairs and used to set additional variables under the device node. A PCI device emulation driver can provide its own hook to override the parsing of the additonal '-s' arguments after the device type. After the configuration phase as completed, the init_pci hook then walks the "pci.<bus>.<slot>.<func>" nodes. It uses the "device" value to find the device model to use. The device model's init routine is passed a reference to its nvlist node in the configuration tree which it can query for specific variables. The result is that a lot of the string parsing is removed from the device models and centralized. In addition, adding a new variable just requires teaching the model to look for the new variable. - For '-l' options, a similar model is used where the string is parsed into values that are later read during initialization. One key note here is that the serial ports use the commonly used lowercase names from existing documentation and examples (e.g. "lpc.com1") instead of the uppercase names previously used internally in bhyve.

Refactor configuration management in bhyve. Replace the existing ad-hoc configuration via various global variables with a small database of key-value pairs. The database supports heirarchical keys using a MIB-like syntax to name the path to a given key. Values are always stored as strings. The API used to manage configuation values does include wrappers to handling boolean values. Other values use non-string types require parsing by consumers. The configuration values are stored in a tree using nvlists. Leaf nodes hold string values. Configuration values are permitted to reference other configuration values using '%(name)'. This permits constructing template configurations. All existing command line arguments now set configuration values. For devices, the "-s" option parses its option argument to generate a list of key-value pairs for the given device. A new '-o' command line option permits setting an individual configuration variable. The key name is always given as a full path of dot-separated components. A new '-k' command line option parses a simple configuration file. This configuration file holds a flat list of 'key=value' lines where the 'key' is the full path of a configuration variable. Lines starting with a '#' are comments. In general, bhyve starts by parsing command line options in sequence and applying those settings to configuration values. Once this is complete, bhyve then begins initializing its state based on the configuration values. This means that subsequent configuration options or files may override or supplement previously given settings. A special 'config.dump' configuration value can be set to true to help debug configuration issues. When this value is set, bhyve will print out the configuration variables as a flat list of 'key=value' lines. Most command line argments map to a single configuration variable, e.g. '-w' sets the 'x86.strictmsr' value to false. A few command line arguments have less obvious effects: - Multiple '-p' options append their values (as a comma-seperated list) to "vcpu.N.cpuset" values (where N is a decimal vcpu number). - For '-s' options, a pci.<bus>.<slot>.<function> node is created. The first argument to '-s' (the device type) is used as the value of a "device" variable. Additional comma-separated arguments are then parsed into 'key=value' pairs and used to set additional variables under the device node. A PCI device emulation driver can provide its own hook to override the parsing of the additonal '-s' arguments after the device type. After the configuration phase as completed, the init_pci hook then walks the "pci.<bus>.<slot>.<func>" nodes. It uses the "device" value to find the device model to use. The device model's init routine is passed a reference to its nvlist node in the configuration tree which it can query for specific variables. The result is that a lot of the string parsing is removed from the device models and centralized. In addition, adding a new variable just requires teaching the model to look for the new variable. - For '-l' options, a similar model is used where the string is parsed into values that are later read during initialization. One key note here is that the serial ports use the commonly used lowercase names from existing documentation and examples (e.g. "lpc.com1") instead of the uppercase names previously used internally in bhyve.
