| | | | | | | | | Make ATA_CAM wrapper to report SATA power management capabilities to CAM to make it configure device to initiate transitions if controller configured to accept them. This makes hint.ata.X.pm_level=1 mode working. Notes: svn path=/stable/8/; revision=215777

* MFC r214016:Alexander Motin2010-11-021-0/+21
| | | | | | | | | | | | | | | | Set of legacy mode SATA enchancements: - Implement proper combined mode decoding for Intel controllers to properly identify SATA and PATA channels and associate ATA channels with SATA ports. This fixes wrong reporting and in some cases hard resets to wrong SATA ports. - Improve SATA registers support to handle hot-plug events and potentially interface errors. For ICH5/6300ESB chipsets these registers accessible via PCI config space. For later ones they may be accessible via PCI BAR(5). - For controllers not generating interrupts on hot-plug events, implement periodic status polling. Use it to detect hot-plug on Intel and VIA controllers. Same probably could also be used for Serverworks and SIS. Notes: svn path=/stable/8/; revision=214671

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Large set of CAM improvements: - Unify bus reset/probe sequence. Whenever bus attached at boot or later, CAM will automatically reset and scan it. It allows to remove duplicate code from many drivers. - Any bus, attached before CAM completed it's boot-time initialization, will equally join to the process, delaying boot if needed. - New kern.cam.boot_delay loader tunable should help controllers that are still unable to register their buses in time (such as slow USB/ PCCard/ CardBus devices), by adding one more event to wait on boot. - To allow synchronization between different CAM levels, concept of requests priorities was extended. Priorities now split between several "run levels". Device can be freezed at specified level, allowing higher priority requests to pass. For example, no payload requests allowed, until PMP driver enable port. ATA XPT negotiate transfer parameters, periph driver configure caching and so on. - Frozen requests are no more counted by request allocation scheduler. It fixes deadlocks, when frozen low priority payload requests occupying slots, required by higher levels to manage theit execution. - Two last changes were holding proper ATA reinitialization and error recovery implementation. Now it is done: SATA controllers and Port Multipliers now implement automatic hot-plug and should correctly recover from timeouts and bus resets. - Improve SCSI error recovery for devices on buses without automatic sense reporting, such as ATAPI or USB. For example, it allows CAM to wait, while CD drive loads disk, instead of immediately return error status. - Decapitalize diagnostic messages and make them more readable and sensible. - Teach PMP driver to limit maximum speed on fan-out ports. - Make boot wait for PMP scan completes, and make rescan more reliable. - Fix pass driver, to return CCB to user level in case of error. - Increase number of retries in cd driver, as device may return several UAs.

| | | | | | | | | | | Unbreak the ata_atapi() usage. Since r200171 (MFC'ed in r200432) the mode setting functions get a ata_device type device passed instead of a ata_channel one, thus ata_atapi() has to be adjusted accordingly. Reviewed by: mav Notes: svn path=/stable/8/; revision=200611

| | | | | | | | | | | | | | | | | | | | | Introduce ATA_CAM kernel option, turning ata(4) controller drivers into cam(4) interface modules. When enabled, this option deprecates all ata(4) peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers (ada, cd, ...) and interfaces to be natively used instead. As side effect of this, ata(4) mode setting code was completely rewritten to make controller API more strict and permit above change. While doing this, SATA revision was separated from PATA mode. It allows DMA-incapable SATA devices to operate and makes hw.ata.(ata|atapi)_dma tunable work again. Also allow ata(4) controller drivers (except some specific or broken ones) to handle larger data transfers. Previous constraint of 64K was artificial and is not really required by PCI ATA BM specification or hardware. Submitted by: nwitehorn (powerpc part) Notes: svn path=/stable/8/; revision=200432

* MFC 196403: Temporarily revert the new-bus locking for 8.0 release.John Baldwin2009-08-201-19/+15

* Make the newbus subsystem Giant free by adding the new newbus sxlock.Attilio Rao2009-08-021-15/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.

* Revert my ata_identify()/ata_reinit() related changes: r189166, r189091Alexander Motin2009-02-281-46/+41
| | | | | | | | | | | | | | | | | and partially r188903. Revert breaks new drives detection on reinit to the state as it was before me, but fixes series of new bugs reported by some people. Unconditional queueing of ata_completed() calls can lead to deadlock if due to timeout ata_reinit() was called at the same thread by previous ata_completed(). Calling of ata_identify() on ata_reinit() in current implementation opens numerous races and deadlocks. Problems I was touching here are still exist and should be addresed, but probably in different way. Notes: svn path=/head/; revision=189195

Reentering of probe call checked inside of it. Give device own knowledge about it's type (ata/atapi/atapicam). It is not a good idea to ask channel status for device type inside ata_getparam().

Attach and detach are sending requests to drives and sleep waiting for results. But ata_finish() can be called directly from interrupt handler where sleeping is prohibited, so we must break this chain somewhere. This place seems to fit best.

Rework SATA hot-plug events handling. Instead of unsafe duplicate implementation use common ata_reinit() to handle all state changes.

If you just config KERNEL as usual there should be no apparent changes, you'll get all chipset support code compiled in. However there is now a way to only compile in code for chipsets needed on a pr vendor basis. ATA now has the following "device" entries: atacore: ATA core functionality, always needed for any ATA setup atacard: CARDBUS support atacbus: PC98 cbus support ataisa: ISA bus support atapci: PCI bus support only generic chipset support. ataahci: AHCI support, also pulled in by some vendor modules. ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, atamarvell, atamicron, atanational, atanetcell, atanvidia, atapromise, ataserverworks, atasiliconimage, atasis, atavia; Vendor support, ie atavia for VIA chipsets atadisk: ATA disk driver ataraid: ATA softraid driver atapicd: ATAPI cd/dvd driver atapifd: ATAPI floppy/flashdisk driver atapist: ATAPI tape driver atausb: ATA<>USB bridge atapicam: ATA<>CAM bridge This makes it possible to config a kernel with just VIA chipset support by having the following ATA lines in the kernel config file: device atacore device atapci device atavia And then you need the atadisk, atapicd etc lines in there just as usual. If you use ATA as modules loaded at boot there is few changes except the rename of the "ata" module to "atacore", things looks just as usual. However under atapci you now have a whole bunch of vendor specific drivers, that you can kldload individually depending on you needs. Drivers have the same names as used in the kernel config explained above. Notes: svn path=/head/; revision=183724
