33 .Nd Qlogic FEPS and FAS366 SCSI driver
35 To compile this driver into the kernel,
36 place the following lines in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
45 driver provides support for the
49 controller chips found in a wide variety of systems and peripheral boards.
66 driver should be used in place of the
69 .Sh IMPLEMENTATION NOTES
70 During the boot sequence, the
73 searches the linked list for LUN info by LUN ID.
74 At this point the driver will attach on that instance,
75 and then attempt to attach every sub-device.
77 There are at least 4 variations of the
78 configuration 3 register.
79 A second config register must be loaded to inquire the chip revision,
82 function will not set the defaults correctly.
84 The drive attach routine attempts to set the appropriate
85 bit to put the chip into Fast
87 mode so that it does not
88 have to be figured out each time.
89 This will then be stored in the
91 registers for later use.
95 driver makes use of the
99 engine which contains three independent
100 channels designed to interface with
104 an AM7990 Ethernet controller;
105 and certain types of parallel port hardware.
106 As such this driver may eventually replace the
108 driver for network hardware.
110 The following driver specific error messages
113 .It "esp: cannot map %d segments"
114 The device was unable to map segments while mapping the
119 .It "unknown variant %d, devices not attached"
120 An unknown version of the card was found and devices will
122 .It "Unhandled function code %d"
123 The device returned a function code which the driver is
124 unable to handle, most likely during negotiation.
125 .It "esp:%d:%d: selection failed %d left in FIFO"
126 The target left the command phase prematurely.
127 If a command did not reach the device then it will
128 be reported as shown above.
129 .It "invalid state: %d"
130 The device has reached an invalid state.

153 driver was then ported to
156 .An Scott Long Aq scottl@FreeBSD.org .
158 This manual page was written by
159 .An Tom Rhodes Aq trhodes@FreeBSD.org
160 instead of porting the original from
165 driver includes the sbus front-end but lacks the
168 Thus it can only support the
176 machines at this time.
178 This driver should eventually replace the
180 driver, but that requires porting the
182 front-end mentioned above.
