The headers are handled differently in Linux where local includes (those using "'s instead of <>'s) are allowed. Don't map our interrupt until after we are fully setup to handle interrupts. Our interrupt line may be shared so an interrupt could occur at any time. aic7xxx.c: Remove linux header ifdefs. current->curr to avoid Linux's use of current as a #define for the current task on some architectures. Add a helper function, ahc_assert_atn(), for use in message phases we handle manually. This hides the fact that U160 chips with the expected phase matching disabled need to have SCSISIGO updated differently. if (ahc_check_residual(scb) != 0) ahc_calc_residual(scb); else ahc_set_residual(scb, 0); becomes: ahc_update_residual(scb); Modify scsi parity error (or CRC error) handling to reflect expected phase being disabled on U160 chips. Move SELTO handling above BUSFREE handling so we can use the new busfree interrupt behavior on U160 chips. In ahc_build_transfer_msg() filter the period and ppr_options prior to deciding whether a PPR message is required. ppr_options may be forced to zero which will effect our decision. Correct a long standing but latent bug in ahc_find_syncrate(). We could choose a DT only rate even though DT transfers were disabled. In the CAM environment this was unlikely as CAM filters our rate to a non-DT value if the device does not support such rates. When displaing controller characteristics, include the speed of the chip. This way we can modify the transfer speed based on optional features that are enabled/disabled in a particular application. Add support for switching from fully blown tagged queing to just using simple queue tags should the device reject an ordered tag. Remove per-target "current" disconnect and tag queuing enable flags. These should be per-device and are not referenced internally be the driver, so we let the OSM track this state if it needs to. Use SCSI-3 message terminology. aic7xxx.h: The real 7850 does not support Ultra modes, but there are several cards that use the generic 7850 PCI ID even though they are using an Ultra capable chip (7859/7860). We start out with the AHC_ULTRA feature set and then check the DEVSTATUS register to determine if the capability is really present. current -> curr ahc_calc_residual() is no longer static allowing it to be called from ahc_update_residual() in aic7xxx_inline.h. Update some serial eeprom definitions for the latest BIOS versions. aic7xxx.reg: Add a combined DATA_PHASE mask to the SCSIPHASE register definition to simplify some sequencer code. aic7xxx.seq: Take advantage of some performance features available only on the U160 chips. The auto-ack feature allows us to ack data-in phases up to the data-fifo size while the sequencer is still setting up the DMA engine. This greatly reduces read transfer latency and simplifies testing for transfer complete (check SCSIEN only). We also disable the expected phase feature, and enable the new bus free interrupt behavior, to avoid a few instructions. Re-arrange the Ultra2+ data phase handling to allow us to do more work in parallel with the data fifo flushing on a read. On an SDTR, ack the message immediately so the target can prepare the next phase or message byte in parallel with our work to honor the message. aic7xxx_93cx6.c: Remove linux header ifdefs. aic7xxx_freebsd.c: current -> curr Add a module event handler. Handle tag downgrades in our ahc_send_async() handler. We won't be able to downgrade to "basic queuing" until CAM is made aware of this queuing type. aic7xxx_freebsd.h: Include cleanups. Define offsetof if required. Correct a few comments. Update prototype of ahc_send_async(). aic7xxx_inline.h: Implement ahc_update_residual(). aic7xxx_pci.c: Remove linux header ifdefs. Correct a few product strings. Enable several U160 performance enhancing features. Modify Ultra capability determination so we will enable Ultra speeds on devices with a 7850 PCI id that happen to really be a 7859 or 7860. Don't map our interrupt until after we are fully setup to handle interrupts. Our interrupt line may be shared so an interrupt could occur at any time. |
