Make MAXPHYS tunable. Bump MAXPHYS to 1M. Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work. Changes to cam/, dev/ahci, dev/ata, dev/mpr, dev/mpt, dev/mvs, dev/siis, where either submitted by, or based on changes by mav.

sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Fix a braino in r236469; the number of DMA tags required for handling MAXPHYS should be based on PAGE_SIZE rather than SYM_CONF_DMA_BOUNDARY. While at it, reuse the SYM_CONF_MAX_SG macro for specifying the maximum number of DMA tags so sym(4) itself doesn't size memory beyond what's required for handling MAXPHYS.

- When creating the DMA tag for user data, don't ask for more segments than required for handling MAXPHYS and report the resulting maximum I/O size to CAM instead of implicitly limiting it to DFLTPHYS. - Move the variables of sym_action2() out of nested scope as required by style(9) and remove extraneous curly braces. - Replace a magic value for PCIR_COMMAND with the appropriate macro. - Use DEVMETHOD_END. - Use NULL instead of 0 for pointers. Tested with a HBA donated by wilko. MFC after: 3 days

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)

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.

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.

- Add year 2000 copyright to driver files. - 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.

* 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.

New `sym' device driver optimized for the Symbios/LSI 53C896/53C895A/53C1010 PCI SCSI controllers. This driver also supports the following Symbios/LSI PCI SCSI chips: 53C810A, 53C825A, 53C860, 53C875, 53C876, 53C885, 53C895. However, it does NOT support earlier chips as the following ones: 53C810, 53C815, 53C825. See README.sym for more details. Submitted-by: Gerard Roudier <groudier@club-internet.fr>
