- move status handling in siop_scsicmd_end(), it's better than in siop_intr()
- define 2 internal SIOP status, for "no status reported by device" and
reset condition
- add a list of "urgent" command, to be executed before the list of command
queued the normal way; this is used for command which got aborted
by a QUEUE FULL and have to be requeued in order.
- Don't accept to send a Q_TAG message not immediatly folowing a IDENTIFY
Implement SCBUSACCEL ioctl.
Snapshot of work in progress on tagged queuing: we can send/receive
queue tag messages. Infrastructure to manage multiple commands per
devices not here yet.
Reset the scsi bus at attach time, to be sure all devices start in narrow/async
mode.
Defer sync/wide negotiation until after whe have a valid
xs->sc_link->device_softc, so that we can honnor the NOSYNC/NOWIDE quirks.
<vm/pglist.h> -> <uvm/uvm_pglist.h>
<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
<vm/vm_object.h> -> nothing
<vm/vm_pager.h> -> into <uvm/uvm_pager.h>
also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.
- on a phase mismatch, do byte recovery only if we were in data phase.
Otherwise just clear the fifo.
- Properly handle reject of a sync or wide negotiation.
'command slots' in which the host can put command and wait for the script
to start them
- Change siop.c to do full disconnect/reslelect, allowing as much as one
command per target/lun to run in parallel.
- Fix bug in registers init where a board without BIOS would end at
ID 0 (now the driver works on alpha too).
- better handling of messages, sending back a MSG_EXT_SDTR in response to an
incoming MSG_EXT_SDTR, and MSG_MESSAGE_REJECT for unhandled messages.
- fix use of bus_dmamap_sync() and htole32().
- supports shared interrups
- change some int8 and int16 to int, for alpha and mips benefits ( suggested by
Toru Nishimura)
(the name 'siop' is still being discussed, may change).
Only basic disconnect/reselect for now, no sync/wide negotiation.
Tested with 810A, 875 and 895 on i386 only.
The bus-independant part should also be able to handle the 53c720 and 53c770.
A new driver with enhanced script should appear for the 825/875/895 'soon'.
