Log Message:
Pull up following revision(s) (requested by kardel in ticket #932):
sys/dev/pci/mpii.c: revision 1.2
sys/dev/pci/mpii.c: revision 1.3
Allow 8 luns instead of 1. This enables access to the changer device on
a Dell PV-124T:
ch0 at scsibus0 target 9 lun 1: <DELL, PV-124T, 0086> changer removable
ch0: 16 slots, 1 drive, 1 picker, 0 portals
fix issues when reading variable block sized tapes.
symptoms:
generic HBA error on console when reading
with a larger blocksize. blocks read
are padded to requested block size with
a 5a... a5... pattern.
problems fixed:
- controller scsi_status values did not match
the ones used by the spsipi layer.
a mapping function was introduced.
- when experiencing an underrun (read 64k and
get a 63k block) the controller posted
not a SUCCESS status but CHECK status. handle
that like SUCCESS adjusting xs->resid and set
XS_SENSE.
now the correct data amount is returned and
nothing is 'added' and no 'generic HBA error'
occurs.
- make decisions using variables and constants
from the controller domain.
