ed34d0ade2 Turn on interrupt-entropy harvesting for all/any mass storage devices
I could find. I have no doubt missed a couple.

Interrupt entropy harvesting is still conditional on the
kern.random.sys.harvest_interrupt sysctl.

b1bec479be Fix:
- Missing cpu_to_scr() added (endian-ness).

Improvement (fix|workaroung??):
- Blindly firing a PPR can lead to some messy situations due to
  various causes or misfeatures, for example:
  * The 53C1010-[33|66] supports offset 62 in DT mode, but only
    offset 31 in ST mode. As a result, a PPR(DT, offset 62)
    responded with PPR(ST, any offset > 31) must be rejected.
  * A device that doesn't know about PPR should reject it, but
    may also be confused by this message.
  When a PPR encounters problems, the driver now patches the goal
  transfer settings for legacy negotiations to be performed later
  with the offending target. This give a chance for bad situations
  to be fixed automagically.

3c9013e257 A couple of chip errata work-arounds refined:
- When used on a 33MHz PCI BUS, the 53C1010-66 revision 0
  requires extra clocks to be inserted in data out phase.
  Revision 1 is fixed.
- The 53C1010-33 revision 1 requires internal cycles to be
  disabled due to possible contentions on IO registers.
  Revision 2 is fixed.
Fix:
- The probing of HVD from GPIO3 bit by the driver was reversed.
  The driver could misprobe the bus mode of a 825 or 875 chip
  that was not previously initialized (no BIOS for example).

46aa3347cb Convert all users of fldoff() to offsetof(). fldoff() is bad
because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.

Define __offsetof() in <machine/ansi.h>

Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>

Remove myriad of local offsetof() definitions.

Remove includes of <stddef.h> in kernel code.

NB: Kernelcode should *never* include from /usr/include !

Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.

Deprecate <struct.h> with a warning.  The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

aeab966bdd PR: kern/20895
PR kern/20895:
- Add FE_DAC new feature flag to distinguish between
  64 bit PCI addressing (DAC cycles) and 64 bit PCI
  interface (64 bit Memory BARs).
- Properly deal with chips that have a 32 bit PCI
  interface but support and may generate DAC.
  (Only SYM53C895A for now).

PR misc/17584 (at least partially addressed):
- Try detecting hardware combinations that trigger
  spurious PCI master parity error detections by the
  PCI chip. This work-around is implemented in the
  `snooptest' routine and consists in retrying with
  PCI master parity checking disabled if such an
  error is reported by the PCI chip during this test.

Other:
- Fix a tiny bug in WIDE negotiation that was very
  unlikely to be triggerred. The BUS width was wrongly
  compared against chip's max. offset.

3b2b8a84d3 - Various comment fixes and additions.
- Add 2 explicit (paranoid?) memory barriers in the
  interrupt code (After the reading of the `flag' and
  prior to looking at the data, of course. :-) ).
- Remove obsolete informations from the README.sym file.

This commit actually results in no object difference

e19c49c532 Fix a problem of user settings from TEKRAM NVRAM
layout introduced in driver 1.5.3. The driver was
confused by the bogus TEKRAM table used to translate
user sync. setting to SCSI sync. factor.
Btw, the new TEKRAM DC-390 U3D and U3W Ultra-160
controllers seem to be using BIOS from SYMBIOS/LSI
and thus SYMBIOS NVRAM layout.
If that means that TEKRAM will now offer real
SYMBIOS software compatible SCSI controllers, then
it is a *GREAT NEWS*.

c5595f9dd0 This new version adds support for early NCR chips.
53C810 non 'A', 53C815 and 53C825 non 'A' are now
attached by the driver (by default).
The driver uses a different SCRIPTS set based on
MEMORY MOVE instructions for these chips.

2 SCRIPTS sets (firmwares) numbered #1 and #2 are
used for the whole support of the 53C8XX family
to get possible:

- FW #1 : Only based on MEMORY MOVE instructions.
          Selected for 810, 815, 825.
- FW #2 : LOAD/STORE based. This is the firmware
          also used by previous driver versions.
          Selected for other chips.

When both `ncr' and `sym' are configured, `sym'
will now attach all the 53C8XX devices by default.
Previous balancing between `ncr' and `sym' can be
preserved by:

- Either editing sym_conf.h and commenting the
  following compile option:
     #define SYM_CONF_GENERIC_SUPPORT
  (This also saves about 3.5Kb of kernel memory).

- Or setting kernel config option
    SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40)

18dfcb3d0e Second patch that prepares for the addition of the
multi-firmware support. This patch just changes
numerous names in the driver sources and is actually
nilpotent. This has been checked by comparing the
generated assembly code.

The names that have been changed are related to the
script names. They were named `script' and `script H'.
They are now named respectively `script A' and
`script B'.

454af27b5c First patch that prepares for the adding of multi-firmware
support. Changes are rather simplifications of the SCRIPTS
interface (prior to complexifying it again;) ), dead code
removes and comment fixes.

Code removed:
- Handling of kernel variables referenced from SCRIPTS.
- Handling of selection without ATN.

Slightly rewritten:
- Handling of illegal phase (4/5) and data overrun conditions.

Simplifications:
- Extended error flag and bits now only set from the C code.
- Move the extended error status (xerr_status) and nego
  status (nego_status) outside the data structure accessed
  by SCRIPTS (struct dsb).
- Get rid of the script status field (scr_st).
- Only patch SCR_NO_OP SCRIPTS instructions to adapt SCRIPTS
  to actual chip capabilities.

Cosmetic changes:
- Miscellaneous comments in SCRIPTS.
- FreeBSD_4_Bus define replaced by FreeBSD_Bus_Io_Abstraction.

45b318264e This new driver version uses the DMA mapping interface
introduced in FreeBSD-4.0. The driver is now full up-to-date
with regards to the current kernel interfaces.

Another significant change in this driver version applies
to the checking of the data direction. The driver is now
able to check against the expected data direction in any
circumstance and will not hang either if direction is wrong
at the start of the IO, or if for some weird reason,
the device changes to the wrong direction during the IO.

This driver version is still usable under FreeBSD 3.2/3.3,
since it only requires CAM, other kernel interface dependencies
being #if'ed in the sources according to kernel version.
But, in order to use the driver under those early kernel
versions, user has to move the driver sources by hand and make
appropriate tiny changes to let the kernel know about the driver.

Other changes:
- Remove the debugging stuff for WSR bit.
- Get rid of some warnings about volatile being discarded.

7a35ada03e Simplifications:
- 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.

f7c17b70a8 * The C1010 stepping B0 (Rev 1) tested OK for DT transfers without the U3EN
broken bit work-around enabled.
* Fixed a bug that made MDP not work. (However, MDP is actually not tested
  due to lack of hardware using this feature).
* Chip table changed to support the C1010 B0 w/o the U3EN bit work-around
  enabled.
* Add the SYM_SETUP_MAX_LUN, SYM_SETUP_LP_PROBE_MAP (used to tell the
  driver about chips that are to be claimed with lower priority than old
  PCI bus based driver (typically the ncr)), SYM_SETUP_SCSI_DIFF, and
  SYM_SETUP_PCI_PARITY options.
