| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | modularize it so that new transports can be created. Add a transport for SATA Add a periph+protocol layer for ATA Add a driver for AHCI-compliant hardware. Add a maxio field to CAM so that drivers can advertise their max I/O capability. Modify various drivers so that they are insulated from the value of MAXPHYS. The new ATA/SATA code supports AHCI-compliant hardware, and will override the classic ATA driver if it is loaded as a module at boot time or compiled into the kernel. The stack now support NCQ (tagged queueing) for increased performance on modern SATA drives. It also supports port multipliers. ATA drives are accessed via 'ada' device nodes. ATAPI drives are accessed via 'cd' device nodes. They can all be enumerated and manipulated via camcontrol, just like SCSI drives. SCSI commands are not translated to their ATA equivalents; ATA native commands are used throughout the entire stack, including camcontrol. See the camcontrol manpage for further details. Testing this code may require that you update your fstab, and possibly modify your BIOS to enable AHCI functionality, if available. This code is very experimental at the moment. The userland ABI/API has changed, so applications will need to be recompiled. It may change further in the near future. The 'ada' device name may also change as more infrastructure is completed in this project. The goal is to eventually put all CAM busses and devices until newbus, allowing for interesting topology and management options. Few functional changes will be seen with existing SCSI/SAS/FC drivers, though the userland ABI has still changed. In the future, transports specific modules for SAS and FC may appear in order to better support the topologies and capabilities of these technologies. The modularization of CAM and the addition of the ATA/SATA modules is meant to break CAM out of the mold of being specific to SCSI, letting it grow to be a framework for arbitrary transports and protocols. It also allows drivers to be written to support discrete hardware without jeopardizing the stability of non-related hardware. While only an AHCI driver is provided now, a Silicon Image driver is also in the works. Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware is possible and encouraged. Help with new transports is also encouraged. Submitted by: scottl, mav Approved by: re Notes: svn path=/head/; revision=195534

* A number of significant enhancements to the ciss driver:Scott Long2008-07-114-150/+494
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. The FreeBSD driver was setting an interrupt coalesce delay of 1000us for reasons that I can only speculate on. This was hurting everything from lame sequential I/O "benchmarks" to legitimate filesystem metadata operations that relied on serialized barrier writes. One of my filesystem tests went from 35s to complete down to 6s. 2. Implemented the Performant transport method. Without the fix in (1), I saw almost no difference. With it, my filesystem tests showed another 5-10% improvement in speed. It was hard to measure CPU utilization in any meaningful way, so it's not clear if there was a benefit there, though there should have been since the interrupt handler was reduced from 2 or more PCI reads down to 1. 3. Implemented MSI-X. Without any docs on this, I was just taking a guess, and it appears to only work with the Performant method. This could be a programming or understanding mistake on my part. While this by itself made almost no difference to performance since the Performant method already eliminated most of the synchronous reads over the PCI bus, it did allow the CISS hardware to stop sharing its interrupt with the USB hardware, which in turn allowed the driver to become decoupled from the Giant-locked USB driver stack. This increased performance by almost 20%. The MSI-X setup was done with 4 vectors allocated, but only 1 vector used since the performant method was told to only use 1 of 4 queues. Fiddling with this might make it work with the simpleq method, not sure. I did not implement MSI since I have no MSI-specific hardware in my test lab. 4. Improved the locking in the driver, trimmed some data structures. This didn't improve test times in any measurable way, but it does look like it gave a minor improvement to CPU usage when many processes/threads were doing I/O in parallel. Again, this was hard to accurately test. Notes: svn path=/head/; revision=180454

| | | | | | | | | | | | | | | | | | | | | | | | the CAM_NEW_TRAN_CODE that has been in the tree for some years now. This first step consists solely of adding to or correcting CAM_NEW_TRAN_CODE pieces in the kernel source tree such that a both a GENERIC (at least on i386) and a LINT build with CAM_NEW_TRAN_CODE as an option will compile correctly and run (at least with some the h/w I have). After a short settle time, the other pieces (making CAM_NEW_TRAN_CODE the default and updating libcam and camcontrol) will be brought in. This will be an incompatible change in that the size of structures related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change in both size and content. However, basic system operation and basic system utilities work well enough with this change. Reviewed by: freebsd-scsi and specific stakeholders Notes: svn path=/head/; revision=163816
