* MFC r315908: Unify initiator and target DMA setup and command sending.Alexander Motin2017-04-241-18/+17

* MFC r315579, r315670: Add initial support for multiple MSI-X vectors.Alexander Motin2017-04-021-11/+11
| | | | | | | | | | For 24xx and above use 2 vectors (default and response queue). For 26xx and above use 3 vectors (default, response and ATIO queues). Due to global lock interrupt hardlers never run simultaneously now, but at least this allows to save one regitster read per interrupt. Notes: svn path=/stable/10/; revision=316399
* MFC r315307: Refactor interrupt handling.Alexander Motin2017-03-291-12/+20
| | | | | | | | | | | | | Instead of single isp_intr() function doing all possible magic, introduce four different functions to handle mailbox operation completions, async events, response and ATIO queues. The goal is to isolate different code paths to make code more readable, and to make easier support for multiple interrupt vectors. Even oldest hardware in many cases can identify what code path it should run on interrupt. Contemporary hardware can assign them to different interrupt vectors.

* Reform the busdma API so that new types may be added without modifyingKonstantin Belousov2013-02-121-39/+11
| | | | | | | | | | | | | | | | | | | | | | | | every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.

* Temporarily desupport simultaneous target and initiator mode.Matt Jacob2007-04-021-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | When the linux port changes were imported which split the target command list to be separate from the initiator command list and the handle format changed to encode a type in the handle the implications to the function isp_handle_index (which only the NetBSD/OpenBSD/FreeBSD ports use) were overlooked. The fault is twofold: first, the index into the DMA maps in isp_pci is wrong because a target command handle with the type bit left in place caused a bad index (and panic) into dma map. Secondly, the assumption of the array of DMA maps in either PCS or SBUS attachment structures is that there is a linear mapping between handle index and DMA map index. This can no longer be true if there are overlapping index spaces for initiator mode and target mode commands. These changes bandaid around the problem by forcing us to not have simultaneous dual roles and doing the appropriate masking to make sure things are indexed correctly. A longer term fix is being devloped. Notes: svn path=/head/; revision=168240

* Remove dependency on ispfw and firmware as modules.Matt Jacob2006-12-101-3/+1
| | | | | | | | | | | | | | | | | | | | Either they're there early and the ispfw sets have registered themselves, or they're not. The module dependency stuff isn't quite what we want anyway. If the user doesn't want the load placed on system memory by loading the firmware, they don't specify it to be loaded (either by being linked in or via being a module to be loaded and then hooked in with firmware(9)). It doesn't then make sense to then override what they want by pulling it in anyway. This might be able to work if we were able to pull in just exactly what we needed for the card we have- but that's an optimization left for the future. Notes: svn path=/head/; revision=165061

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | loading for the QLogic cards. Because isp(4) exists before the root is mounted, it's not really possible for us to use the kernel's linker to load modules directly from disk- that's really too bad. However, the this is still a net win in in that the firmware has been split up on a per chip (and in some cases, functionality) basis, so the amount of stuff loaded *can* be substantially less than the 1.5MB of firmware images that ispfw now manages. That is, each specific f/w set is now also built as a module. For example, QLogic 2322 f/w is built as isp_2322.ko and Initiator/Target 1080 firmware is built as isp_1080_it.ko. For compatibility purposes (i.e., to perturb folks the least), we also still build all of the firmware as one ispfw.ko module. This allows us to let 'ispfw_LOAD' keep on working in existing loader.conf files. If you now want to strip this down to just the firmware for your h/w, you can then change loader.conf to load the f/w you specifically want. We also still allow for ispfw to be statically built (e.g., for PAE and sparc64). Future changes will look at f/w unloading and also role switching that then uses the kernel linker to load different ips f/w sets. MFC after: 2 months Notes: svn path=/head/; revision=160212

Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64.

This allows us to support the 2322 (and 2422 4Gb) cards which only come with the 2K Port Login firmware. The 2322 should now work- but we don't have firmware sets for it in ispfw (as the change to load 2K Port Login f/w hasn't been made- that f/w is so big it has to be loaded in more than one chunk). Other changes are the beginnings of cleaning up some long standing target mode issues. The next changes here will incorporate a lot of bug fixes from others. Finally, some copyright cleanup and attempts to make the parts of the driver that are FreeBSD specific start conforming more to FreeBSD style.

* - Introduce an ofw_bus kobj-interface for retrieving the OFW node and aMarius Strobl2004-08-121-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
