102 This driver supports the entire Symbios 53C8XX family of PCI SCSI
111 per IO completion is delivered to the CPU, and that the SCRIPTS processor
112 is never stalled waiting for CPU attention in normal situations.
117 Use of LOAD/STORE instead of MEMORY MOVE allows SCRIPTS to access IO
118 registers internal to the chip (no external PCI cycles).
119 As a result, the driver guarantees that no PCI self-mastering will occur
133 allows the driver to safely probe against bus mode and to set up the chip
136 For other chips that can support HVD but not LVD, the driver has to probe
137 implementation dependent registers (GPIO) in order to detect HVD bus mode.
149 driver will not enable PCI parity checking for 53C8XX devices.
151 checking should not be an option for PCI SCSI controllers, but some
152 systems have been reported to fail using 53C8XX chips, due to spurious or
153 permanent PCI parity errors detected.
