Hello, I just got the appropriate cable this evening and started testing ultra3=20 support for the C1010. After a tiny fix in the SYM driver I got the following: Nov 23 22:39:58 /T35: (probe0:sym1:0:3:0): nego msgout:: 1-6-4-9-0-3e-1-2. Nov 23 22:39:58 /T35: (probe0:sym1:0:3:0): ppr msg in: 1-6-4-9-0-1f-1-2. Nov 23 22:39:58 /T35: (probe0:sym1:0:3:0): ppr: dt=3D2 ofs=3D31 per=3D9 wi= de=3D1 div=3D0 fak=3D0 chg=3D0. Nov 23 22:39:58 /T35: da2 at sym1 bus 0 target 3 lun 0 Nov 23 22:39:58 /T35: da2: <QUANTUM ATLAS IV 18 SCA 0808> Fixed Direct Acc= ess SCSI-3 device=20 Nov 23 22:39:58 /T35: da2: 160.000MB/s transfers (80.000MHz, offset 31, 16= bit), Tagged Queueing Enabled Nov 23 22:39:58 /T35: da2: 17522MB (35885168 512 byte sectors: 255H 63S/T = 2233C) For now, I just tried reads, and they seemed to work reliably. By the way, the only hack I applied to SCSI is the following (scsi_all.c): static struct { u_int period_factor; u_int period;=09/* in 10ths of ns */ } scsi_syncrates[] =3D { + { 0x09, 125 }, { 0x0a, 250 }, { 0x0b, 303 }, { 0x0c, 500 } }; The sync period factor 9 is read by the driver from the controller NVRAM. I will continue testing the beast. For the full support of Ultra3, Justin will provide changes in CAM and SCSI. The cam/scsi hacks I may add with further driver patches are just minimal things that will be obviously discarded.=20 G=E9rard.
