The old Solaris aac driver is simple and stable, 32but with limited functions. 33 34The new Solaris aac driver adds support of the following features: 351. New firmware support: 36 New Communication interface, RawIO command, Large FIB, 64-bit LBA 372. New hardware support: 38 Rocket chip based cards, such as 2820SA 393. Other features: 40 64-bit DMA, Fast IO, firmware version checking, tagged-queuing 414. IOCTL 425. AIF 436. IOP reset 44 45The new Solaris aac 2.0 driver is mainly based on FreeBSD 6.0 aac driver. 46IOP reset, AIF handling, 64-bit LBA, and some other minor features are 47implemented from scratch by Adaptec engineers. They are not supported in 48current FreeBSD aac driver. 49 50Adaptec approves Sun's intention to open source the aac RAID driver for 51commercial Solaris and the Open Solaris community. 52 53aac driver 2.1.14 54=================== 55UART trace support is added in this release: 56 The driver can now make output through the firmware UART trace. You 57 have to set AAC_DEBUG and the appropriate flags in aac_debug_flags, at 58 least AACDB_FLAGS_FW_PRINT to enable the UART trace and any other flags 59 to enable the output class you want to see. 60 To use the tip utility to connect to the UART daughter card, a configu- 61 ration line as below should be added to /etc/remote: 62 aac:\ 63 :dv=/dev/term/a:br#115200:el=^C^S^Q^U^D:ie=%$:oe=^D: 64 65aac driver 2.2.0 66================== 67SPARC platform support is added in this release: 68 To support SPARC, the driver is modified for DDI compliance. The driver 69 now uses DDI compliant functions to access the device's IO and memory 70 spaces for DMA transfers. 71
