* Remove bus_{mem,p}io.h and related code for a micro-optimization on i386nyan2005-05-291-1/+0

| | | | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | - Build SGL's for ATA_PASSTHROUGH commands - Fallback to using the sgl_offset when the opcode is unknown for building SGL's/ - Add ioctl calls for adding and removing units. - Define previously undefined AEN's - Allocate memory for the ioctl payload in multiples of 512bytes. MFC after: 1 week

* Centralize the devstat handling for all GEOM disk device driversphk2003-03-081-2/+2

* Minor updates:msmith2001-05-071-2/+5
| | | | | | | | - Rework of twe_report_request to use the command status value rather than the flags register. (Joel Jacobson @ 3ware) - Update to match some changes in -current vs. stable. MFC in: 1 week
* Major update to the 'twe' driver.msmith2000-10-251-0/+179
- 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.
