* Make the newbus subsystem Giant free by adding the new newbus sxlock.attilio2009-08-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | issues which they found and asked to be changed so 3ware can offcially support the driver. Summary of the most significant changes: - TWE_OVERRIDE is no longer supported - If twe_getparam failed, bogus data would be returned to the caller - Cache the device unit in the twe_drive structure to aid debugging - Add the 3ware driver version. - Proper return error codes for many functions. - Track the minimum queue length statistics - 4.x compat: use the cached unit number from the twe_drive structure instead of the the cached si_drv2. 3ware found that after many loads and unloads that si_drv2 became corrupted. This did not happen in -current. Submitted by: Vinod Kashyap (with modifications by me) Approved by: re (rwatson)

* Major update to the 'twe' driver.msmith2000-10-251-1003/+844
| | | | | | | | | | | | | | | | | | | | | | | | | - Layout reorganisation to enhance portability. The driver now has a relatively MI 'core' and a FreeBSD-specific layer over the top. Since the NetBSD people have already done their own port, this is largely just to help me with the BSD/OS port. - Request ID allocation changed to improve performance (I'd been considering switching to this approach after having failed to come up with a better way to dynamically allocate request IDs, and seeing Andy Doran use it in the NetBSD port of the driver convinced me that I was wasting my time doing it any other way). Now we just allocate all the requests up front. - Maximum request count bumped back to 255 after characterisation of a firmware issue (off-by-one causing it to crash with 256 outstanding commands). - Control interface implemented. This allows 3ware's '3dm' utility to talk to the controller. 3dm will be available from 3ware shortly. - Controller soft-reset feature added; if the controller signals a firmware or protocol error, the controller will be reset and all outstanding commands will be retried.
