| | | | | | | | | | | | | | | of OFW access semantics, in order to allow future support for real-mode OF access and flattened device frees. OF client interface modules are implemented using KOBJ, in a similar way to the PPC PMAP modules. Because we need Open Firmware to be available before mutexes can be used on sparc64, changes are also included to allow KOBJ to be used very early in the boot process by only using the mutex once we know it has been initialized.

This commit also modifies the OFW PCI enumeration procedure on PowerPC to allow the bus to find non-firmware-enumerated devices that Apple likes to add, and adds some useful Open Firmware properties (compat and name) to the pnpinfo string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the change to PCI enumeration on PowerPC, X has started working again on PPC machines with Grackle hostbridges.

* Integrate the new MPSAFE TTY layer to the FreeBSD operating system.Ed Schouten2008-08-201-110/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

* Expand kdb_alt_break a little, most commonly used with the optionPeter Wemm2008-05-041-2/+17
| | | | | | | | | | | | | | | | | | | | | | ALT_BREAK_TO_DEBUGGER. In addition to "Enter ~ ctrl-B" (to enter the debugger), there is now "Enter ~ ctrl-P" (force panic) and "Enter ~ ctrl-R" (request clean reboot, ala ctrl-alt-del on syscons). We've used variations of this at work. The force panic sequence is best used with KDB_UNATTENDED for when you just want it to dump and get on with it. The reboot request is a safer way of getting into single user than a power cycle. eg: you've hosed the ability to log in (pam, rtld, etc). It gives init the reboot signal, which causes an orderly reboot. I've taken my best guess at what the !x86 and non-sio code changes should be. This also makes sio release its spinlock before calling KDB/DDB. Notes: svn path=/head/; revision=178766

Introduce a set of functions ofw_bus_gen_get_*() which use ofw_bus_default_get_devinfo() to provide generic subroutines for implementing the rest of the ofw_bus KOBJ interface in a bus driver. This is inspired by bus_get_resource_list() and bus_generic_rl_*_resource() and allows to reduce code duplication in bus drivers as they only have to provide an ofw_bus_default_get_devinfo() implementation in order to provide the ofw_bus KOBJ interface via ofw_bus_gen_get_*(). - While here add a comment to ofw_bus_if.m describing the intention of the ofw_bus KOBJ interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | subset ("compatible", "device_type", "model" and "name") of the standard properties in drivers for devices on Open Firmware supported busses. The standard properties "reg", "interrupts" und "address" are not covered by this interface because they are only of interest in the respective bridge code. There's a remaining standard property "status" which is unclear how to support properly but which also isn't used in FreeBSD at present. This ofw_bus kobj-interface allows to replace the various (ebus_get_node(), ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type() vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one. This in turn allows to simplify and remove code-duplication in drivers for devices that can hang off of more than one OFW supported bus. - Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the drivers for their children to use the ofw_bus kobj-interface. The IVAR- interfaces of the Central, EBus and FHC are entirely replaced by this. The PCI bus driver used its own kobj-interface and now also uses the ofw_bus one. The IVARs special to the SBus, e.g. for retrieving the burst size, remain. Beware: this causes an ABI-breakage for modules of drivers which used the IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be recompiled. The style-inconsistencies introduced in some of the bus drivers will be fixed by tmm@ in a generic clean-up of the respective drivers later (he requested to add the changes in the "new" style). - Convert the powerpc MacIO bus driver and the drivers for its children to use the ofw_bus kobj-interface. This invloves removing the IVARs related to the "reg" property which were unused and a leftover from the NetBSD origini of the code. There's no ABI-breakage caused by this because none of these driver are currently built as modules. There are other powerpc bus drivers which can be converted to the ofw_bus kobj-interface, e.g. the PCI bus driver, which should be done together with converting powerpc to use the OFW PCI code from sparc64. - Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take advantage of the ofw_bus kobj-interface and simplify them a bit.

The maximum length of OFW property names is 31. I didn't find a maximum length for the device identifiers in the OFW documentation but it certainly is much smaller than 8191, too. - Enable the OFIOCSET ioctl, i.e. move it out from under #if 0. - Don't use openfirm_getstr() for the property value in OFIOCSET, there are also properties whose values aren't strings and it makes sense to use a different maximum length for property values than OFW_NAME_MAX/ OFIOCMAXNAME. The maximum accepted property value is defined in openfirmio.h as OFIOCMAXVALUE (currently the maximum size of the value of the nvramrc property). - Make OFIOCSET not return EINVAL when OF_setprop() returns a different length for the written value than it was told to write, this is normal for the text string values of the properties in the OFW /options node. Instead, only return EINVAL if OF_setprop() returned -1 (value could not be written or property could not be created). Add a comment about the specialty of the OFW /options node. - Make OFIOCSET return the length of the written value returned by OF_setprop(), just like OF_getprop() does.
