sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

- With the demise of !ATA_CAM, ATA_STATIC_ID is the only ata(4) related option left but actually consumed by ada(4), so move it to opt_ada.h and get rid of opt_ata.h. - Fix stand-alone build of atacore(4) by adding opt_cam.h. - Use __FBSDID. - Use DEVMETHOD_END. - Use NULL instead of 0 for pointers.

Remove all legacy ATA code parts, not used since options ATA_CAM enabled in most kernels before FreeBSD 9.0. Remove such modules and respective kernel options: atadisk, ataraid, atapicd, atapifd, atapist, atapicam. Remove the atacontrol utility and some man pages. Remove useless now options ATA_CAM. No objections: current@, stable@ MFC after: never

Intel NM10 chipset's SATA controller has same PCI ID and revision as ICH7's, but has only 2 SATA ports instead of 4. The worst part is that SStatus and SError registers for missing ports are not implemented and return wrong values (0xffffffff), that caused infinite reset loop. Just ignore that SError value while I found no better way to identify them.

Even if we are skipping SATA hard reset - set power management bits in SControl register. This should make things consistent and help to avoid unexpected PHY events that I've noticed in some cases on VIA controllers.

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.

MFC r200171, r200182, r200275, r200295, r200359: 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)

It makes logic more transparent and is a mandatory step to wrap ATA(4) controller level into ATA-native CAM SIM. - Tune AHCI and SATA2 SiI drivers memory allocation a bit to allow bigger I/O transaction sizes without additional cost.

Add experimental support for SATA interface power management. Feature is controlled by hint.ata.X.pm_level tunable: 0 - PM disabled, old behaviour, default. 1 - device is allowed to initiate PM state change, host is passive. 2 - host initiates PARTIAL state transition every time port is idle. 3 - host initiates SLUMBER state transition every time port is idle. PARTIAL state has up to 100us (50us for me) wakeup latency, but for my ICH8M saves 0.5W of power per drive. SLUMBER state has up to 10ms (3.5ms for me) wakeup latency, but saves 0.8W of power. Modes 2 and 3 are implemented only for AHCI driver now. Interface power management is incompatible with device presence detection (host receives no signal from drive, so unable to monitor it), so later is disabled when PM is used.

Integrate user/mav/ata branch: Add ch_suspend/ch_resume methods for PCI controllers and implement them for AHCI. Refactor AHCI channel initialization according to it. Fix Port Multipliers operation. It is far from perfect yet, but works now. Tested with JMicron JMB363 AHCI + SiI 3726 PMP pair. Previous version was also tested with SiI 4726 PMP.

Use only higher half of device signature to identify device type. Some devices return incorrect values in lower part confusing detection, while higher part itself gives enough information for proper detetion.

Improve ata_reinit(): - protect againtst recursions, - add new devices detection using ata_identify(). Improve ata_identify(): - do not add duplicate device if device already exist. Rework SATA hot-plug events handling. Instead of unsafe duplicate implementation use common ata_reinit() to handle all state changes. All together this gives quite stable and robust cold- and hot-plug operation, invariant to false, lost and duplicate events.

This is the roumored ATA modulerisation works, and it needs a little explanation. 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.
