Add a constant for the controller's stack size and the maximum scsi offset. aic7xxx.seq: Style nit. The source is implied to be the destination unless overridden in an "and" instruction. Update target mode code for changes in identify seen sequencer flags. aic7xxx_pci.c: Ensure that the PCIERRGENDIS bit is set in the PCIERRGEN config space register. Perhaps this is a reason for the spurios parity errors reported on U160 controllers. Honor the AHC_NO_BIOS_INIT flag. Allow PCI interrupt reporting to be disabled, by clearing the PERRRESEN bit in the command register. This option is now enabled via a new softc flag: AHC_DISABLE_PCI_PERR. Disable SERR and pause the controller prior to performing our mmapped I/O test. This should handle the case of controllers that do not "auto-access pause". For legacy controllers, use SCB ram instead of scratch ram since the latter may contain settings left over from the BIOS that we will use if an seeprom is not found. Make use of new ahc_inl/outl() inlines. aic7xxx.h: Reformat a few comments to follow driver style. Add a controller flags that indicate that a controller has not been initialized by the BIOS and whether to disable PCI parity errors.. Remove stack probing softc members. Add a few more syncrate constants that are useful in speed fallback calculations. Add the SHOW_MASKED_ERRORS debug flag. aic7xxx.h: aic7xxx.c: Implement the SCB_SILENT flag. This is useful for hushing up the driver during DV or other operations that we expect to cause transmission errors. The messages will still print if the SHOW_MASKED_ERRORS debug option is enabled. aic7xxx_inline.h: Implement ahc_[in|out][w|l|q]. This removes the need for manual 'or and shift" type operations throughout the driver. aic7xxx.c: Move SELTO dignostic so that the SCB is still valid when we use it for printing path information. If we are narrow, limit syncrate to Ultra2. Don't clobber ppr_options when forcing a renegotiation. The current ppr_options may be referenced while queuing new commands. Don't set our width to unknown when forcing negotiation on narrow controllers. This will confuse the negotiation code into negotiating with a wide message on narrow controllers. Add an "asserting atn" diagnostic with controller/target information. Remove the probe_stack code. The stack is always 4 deep on legacy controllers, so probing is pointless. This also avoids an issue where probing the stack would upset the aic7770. In ahc_reset(), record whether or not we found the controller in a reset state. If the controller was already reset, assume that no BIOS has initialized the controller and ignore left over scratch ram settings. Fix an ifdef bug that caused sequencer debugging to be enabled always. Clear the ultraenb flag in our tstate during startup. The ultraenbled'ness of a device is recorded in the user transfer settings. tstate->ultraenb bitmask indicates which devices we have negotiated an ultra speed with. Just after initialization, we are async. Setting the ultraenb flag while async seems to be harmless, but it was confusing to see the ULTRAENB flag set in the SCB. Enhance residual diagnostic to indicate if the residual if for sense information or normal data transfers. Indicate the features, bugs, and flags set in the softc that are used to control firmware patch download when booting verbose. In ahc_dump_card_state() fix a logic reversal. The SCSIPHASE register only exists on U160 controllers. The SCSISIGI register exists on all controllers. Not the other way around. Also print out the ERROR register. Allow ahc_dump_card_state() to be called when the sequencer is not paused. Add dump card state markers as in the U320 driver. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
