* Don't probe for a disk unless explicitly enabled by a tunable.Peter Grehan2004-12-281-0/+6
| | | | | | | | | | | | This allows boot to proceed on a real system until the issue of calling back into certain OpenFirmware calls (e.g. finddevice) in thread context is understood.

| | | | | | | | | | | | | | | | | modes on a tty structure. Both the ".init" and the current settings are initialized allowing the function to be used both at attach and open time. The function takes an argument to decide if echoing should be enabled. Echoing should not be enabled for regular physical serial ports unless they are consoles, in which case they should be configured by ttyconsolemode() instead. Use the new function throughout.

* - Introduce an ofw_bus kobj-interface for retrieving the OFW node and aMarius Strobl2004-08-122-0/+183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | identifiers, to openfirmio.h as OFIOCMAXNAME, so programs can use it for buffer sizes etc. Note: Although this is only a rough upper limit to make the code more robust and to prevent the allocation of ridiculous amounts of memory, the current limit of one page (8191 + '\0' in openfirm_getstr()) still appears a bit high. 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. Quite useful, at least for debugging. Reviewed by: tmm Notes: svn path=/head/; revision=129587

* Change the disk(9) API in order to make device removal more robust.Poul-Henning Kamp2004-02-181-10/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the "struct disk" were owned by the device driver and this gave us problems when the device disappared and the users of that device were not immediately disappearing. Now the struct disk is allocate with a new call, disk_alloc() and owned by geom_disk and just abandonned by the device driver when disk_create() is called. Unfortunately, this results in a ton of "s/\./->/" changes to device drivers. Since I'm doing the sweep anyway, a couple of other API improvements have been carried out at the same time: The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to DISKFLAG_NEEDSGIANT A version number have been added to disk_create() so that we can detect, report and ignore binary drivers with old ABI in the future. Manual page update to follow shortly. Notes: svn path=/head/; revision=125975
