26aac driver 2.0
27================
28The Solaris aac driver enhancement updates the Solaris aac 1.6 driver
29to a full-fledged one. The old Solaris aac driver is simple and stable,
30but with limited functions.
31
32The new Solaris aac driver adds support of the following features:
331. New firmware support:
34	New Communication interface, RawIO command, Large FIB, 64-bit LBA
352. New hardware support:
36	Rocket chip based cards, such as 2820SA
373. Other features:
38	64-bit DMA, Fast IO, firmware version checking, tagged-queuing
394. IOCTL
405. AIF
416. IOP reset
42
43The new Solaris aac 2.0 driver is mainly based on FreeBSD 6.0 aac driver.
44IOP reset, AIF handling, 64-bit LBA, and some other minor features are
45implemented from scratch by Adaptec engineers. They are not supported in
46current FreeBSD aac driver.
47
48Adaptec approves Sun's intention to open source the aac RAID driver for
49commercial Solaris and the Open Solaris community.
50
51aac driver 2.1.14
52===================
53UART trace support is added in this release:
54        The driver can now make output through the firmware UART trace. You
55        have to set AAC_DEBUG and the appropriate flags in aac_debug_flags, at
56        least AACDB_FLAGS_FW_PRINT to enable the UART trace and any other flags
57	to enable the output class you want to see.
58	To use the tip utility to connect to the UART daughter card, a configu-
59	ration line as below should be added to /etc/remote:
60	aac:\
61		:dv=/dev/term/a:br#115200:el=^C^S^Q^U^D:ie=%$:oe=^D:
62
63aac driver 2.2.0
64==================
65SPARC platform support is added in this release:
66	To support SPARC, the driver is modified for DDI compliance. The driver
67	now uses DDI compliant functions to access the device's IO and memory
68	spaces for DMA transfers.
69
70aac driver 2.2.3
71==================
72MSI interrupts supporting is added in this release:
73	Instead of supporting fixed interrupt only, the driver added the MSI
74	interrupt whenever the HBA card has this feature. In the same time, the
75	driver has replaced all legacy interrupt ddi interfaces callings by 
76	the according ddi_intr_* ones.
77
78aac driver 2.2.5
79==================
80Two new features are included in this release:
81One is Non-DASD support:
82	The driver now supports non-DASD(Non Direct Access Storage Device).
83	This means you can use cdroms and other non-DASD devices with
84	your aac card. Before trying it, make sure your card's firmware support
85	non-DASD access. For some cards, you may need to explicitly enable it
86	through aac BIOS. Make sure nondasd-enable property in aac.conf is
87	switched on.
88The other is FIB dump:
89	The driver now supports FIB contents dumping for driver debugging. To
90	enable it, you need to set AAC_DEBUG and the appropriate flags in
91	aac_debug_fib_flags.
