Significant changes: - Remove obsolete informations from the README.sym file. - Check also against DT_DATA_IN phase on parity/crc error. (Merged from Pamela Delaney's changes in the Linux driver) - Fix support for phase mismatch handling from the C code for the C1010 (only useful for testing issue). - Add an asynchonous notification handler for `lost device' (AC_LOST).

MFC: update sym_hipd.c to revision 1.16.

Previous MFC came from revision 1.13. Fixes the user settings report problem with Tekram layout NVRAM for devices configured for Fast-40 and uses `bus space' instead of legacy IO/MMIO methods. Other changes that make the patch larger than it could have been are not dangerous for -stable and it would have been less safe, in my opinion, to try to revert them prior to this MFC.

- Remove all the code intended to deal with experimental C1010 revisions. This code got useless due to commercial chip revisions having been fixed. Fixes: - Rewrite/rework the WSR condition handling. Previous drivers snooped on the BUS through the SBDL IO register and this has been discovered to trigger a spurious SCSI parity error when WSR had been set by chip and cleared by SCRIPTS prior to reading SBDL bit [0...7]. On the other hand, the C1010 does not use the SWIDE register when synchronous data transfers are taking place and requires a CHMOV (1) WHEN DATA_IN to be performed in order to move to memory the residual byte when WSR is set and the residual byte is useful data. BTW, the new WSR handling by the driver is simpler. - No longer attempt to read from SCRIPTS the SBDL register. This is intended to avoid to be victimized again by any other issue regarding the handling of this register by 8xx chips. Miscellaneous: - The driver is now able to handle the WSR + IGN RESIDUE condition at the end of a DATA IN I/O without need of a programmed interrupt. It is a minor? optimization. - A few other minor cosmetic changes. This driver version fixes notably a permanent SCSI parity error condition at boot that can be triggerred due to recent changes in cam_xpt.c between 1.79 and 1.80. Changes in CAM/XPT are fine, but the new handling of the full INQUIRY may trigger the driver problem when a target returned an odd value in the `additionnal length' field of the INQUIRY response. The diff against previous driver version is large, but it consists approximatively in: - 350 lignes removed and not compiled in previous drivers (They addressed experimental C1010 revisions) - 250 lignes added or changed, half being comments or empty lines. So, in fact, the real changes are about 120 lines of source. About 80 lines address SCRIPTS changes and about 40 lines address C code changes. Approved by: jkh New WSR handling reviewed by Pamela Delaney (For back-porting to Linux sym53c8xx driver 1.6x series)

condition. - 1 line change that allows to balance chips between ncr and sym using pci compat option (not compiled by default in 4.0 but maintains the driver source 3.4 compatible).

2000-01-08T19:58:17Z

- Set MAX_OFFS driver compile option to 63 (was 64 which is wrong). - Fix a typo in the SYMBIOS NVRAM layout structure and add field and bit definition for the support of PIM_NOBUSRESET. - Report to XPT PIM_NOBUSRESET and PIM_SCANHILO if set by user in NVRAM. - Negotiate SYNC immediately after WIDE response from the target as suggested by Justin Gibbs. - Remove some misleading comment about CmdQue handling by CAM. - Apply correctly the MAX_WIDE and MAX_OFFS driver options.
