This is the much rumoured ATA mkIII update that I've been working on. o ATA is now fully newbus'd and split into modules. This means that on a modern system you just load "atapci and ata" to get the base support, and then one or more of the device subdrivers "atadisk atapicd atapifd atapist ataraid". All can be loaded/unloaded anytime, but for obvious reasons you dont want to unload atadisk when you have mounted filesystems. o The device identify part of the probe has been rewritten to fix the problems with odd devices the old had, and to try to remove so of the long delays some HW could provoke. Also probing is done without the need for interrupts, making earlier probing possible. o SATA devices can be hot inserted/removed and devices will be created/ removed in /dev accordingly. NOTE: only supported on controllers that has this feature: Promise and Silicon Image for now. On other controllers the usual atacontrol detach/attach dance is still needed. o Support for "atomic" composite ATA requests used for RAID. o ATA RAID support has been rewritten and and now supports these metadata formats: "Adaptec HostRAID" "Highpoint V2 RocketRAID" "Highpoint V3 RocketRAID" "Intel MatrixRAID" "Integrated Technology Express" "LSILogic V2 MegaRAID" "LSILogic V3 MegaRAID" "Promise FastTrak" "Silicon Image Medley" "FreeBSD PseudoRAID" o Update the ioctl API to match new RAID levels etc. o Update atacontrol to know about the new RAID levels etc NOTE: you need to recompile atacontrol with the new sys/ata.h, make world will take care of that. NOTE2: that rebuild is done differently from the old system as the rebuild is now done piggybacked on read requests to the array, so atacontrol simply starts a background "dd" to rebuild the array. o The reinit code has been worked over to be much more robust. o The timeout code has been overhauled for races. o Support of new chipsets. o Lots of fixes for bugs found while doing the modulerization and reviewing the old code. Missing or changed features from current ATA: o atapi-cd no longer has support for ATAPI changers. Todays its much cheaper and alot faster to copy those CD images to disk and serve them from there. Besides they dont seem to be made anymore, maybe for that exact reason. o ATA RAID can only read metadata from all the above metadata formats, not write all of them (Promise and Highpoint V2 so far). This means that arrays can be picked up from the BIOS, but they cannot be created from FreeBSD. There is more to it than just the missing write metadata support, those formats are not unique to a given controller like Promise and Highpoint formats, instead they exist for several types, and even worse, some controllers can have different formats and its impossible to tell which one. The outcome is that we cannot reliably create the metadata of those formats and be sure the controller BIOS will understand it. However write support is needed to update/fail/rebuild the arrays properly so it sits fairly high on the TODO list. o So far atapicam is not supported with these changes. When/if this will change is up to the maintainer of atapi-cam so go there for questions. HW donated by: Webveveriet AS HW donated by: Frode Nordahl HW donated by: Yahoo!

Major snd_hda driver rewrite: - Huge old hdac driver was split into three independent pieces: HDA controller driver (hdac), HDA CODEC driver (hdacc) and HDA sudio function driver (hdaa). - Support for multichannel recording was added. Now, as specification defines, driver checks input associations for pins with sequence numbers 14 and 15, and if found (usually) -- works as before, mixing signals together. If it doesn't, it configures input association as multichannel. - Signal tracer was improved to look for cases where several DACs/ADCs in CODEC can work with the same audio signal. If such case found, driver registers additional playback/record stream (channel) for the pcm device. - New controller streams reservation mechanism was implemented. That allows to have more pcm devices then streams supported by the controller (usually 4 in each direction). Now it limits only number of simultaneously transferred audio streams, that is rarely reachable and properly reported if happens. - Codec pins and GPIO signals configuration was exported via set of writable sysctls. Another sysctl dev.hdaa.X.reconfig allows to trigger driver reconfiguration in run-time. - Driver now decodes pins location and connector type names. In some cases it allows to hint user where on the system case connectors, related to the pcm device, are located. Number of channels supported by pcm device, reported now (if it is not 2), should also make search easier. - Added workaround for digital mic on some Asus laptops/netbooks.
