I am running FreeBSD/amd64 RELENG_8 on a Dell Optiplex 745. The hard drive in the system is SATA and I have "Normal", not "Legacy" SATA support enabled in the BIOS. (BIOS is V2.6.4.) I am assuming this will enable native AHCI mode for the drive.
I built a kernel with ATA_CAM support, but for some reason the SATA drive is probing at slow, UDMA2, speeds: ada0 at ata2 bus 0 scbus0 target 0 lun 0 ada0: <ST3160812AS 3.ADJ> ATA-7 SATA 2.x device ada0: 33.300MB/s transfers (UDMA2, PIO 8192bytes) ada0: 152587MB (312500000 512 byte sectors: 16H 63S/T 16383C) When I run "camcontrol identify" on the drive, it states the drive is capable of UDMA6 speeds: backup# camcontrol identify ada0 pass0: <ST3160812AS 3.ADJ> ATA-7 SATA 2.x device pass0: 33.300MB/s transfers (UDMA2, PIO 8192bytes) protocol ATA/ATAPI-7 SATA 2.x device model ST3160812AS firmware revision 3.ADJ serial number 5LS8PPDD cylinders 16383 heads 16 sectors/track 63 sector size logical 512, physical 512, offset 0 LBA supported 268435455 sectors LBA48 supported 312500000 sectors PIO supported PIO4 DMA supported WDMA2 UDMA6 Feature Support Enable Value Vendor read ahead yes yes write cache yes yes flush cache yes yes overlap no Tagged Command Queuing (TCQ) no no Native Command Queuing (NCQ) yes 32 tags SMART yes yes microcode download yes yes security yes no power management yes yes advanced power management no no 65278/0xFEFE automatic acoustic management yes yes 254/0xFE 208/0xD0 media status notification no no power-up in Standby no no write-read-verify no no 0/0x0 unload no no free-fall no no data set management (TRIM) no So, why the slower speed? Also, "camcontrol identify" states the drive supports NCQ with up to 32 tags supported, yet "camcontrol tags ada0" reports only 1 device opening, not 32 as I would expect: backup# camcontrol tags ada0 (pass0:ata2:0:0:0): device openings: 1 To enable ATA_CAM AHCI support, I included this in my kernel config file: # ATA and ATAPI devices options ATA_CAM device ahci device atacore device atapci options ATA_STATIC_ID # Static device numbering Is this the correct way to enable ATA_CAM AHCI support? I tried initially including just "options ATA_CAM" and "device ahci" but the resultant kernel would not probe my disk drive as ada0. Does my problem lie with my kernel config or is the Dell Optiplex 745 BIOS brain dead when it comes to AHCI native support? The only option it appears to have in the BIOS is "Normal" and "Legacy" when it comes to the SATA controller mode. I've attached my full kernel config and dmesg at the end of this e-mail. Cheers, Paul.
