2007-02-16[SCSI] aic94xx: tie driver to the major number of the sequencer firmwareJames Bottomley
The sequencer firmware file has both a string (currently showing V17/10c6) and a number (currently set to 1.1). It has become apparent that Adaptec may issue sequencer firmware in the future which could be incompatible with the current driver. Therefore, the driver will be tied to the particular major number of the firmware (i.e. the current driver will load any 1.x firmware). Additionally, the driver will print out both the ascii string and the major number, so with this pach the current firmware will print out aic94xx: Found sequencer firmware version 1.1 (V17/10c6) Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-02-03[SCSI] aic94xx: update for v28 firmwareWu, Gilbert
These changes work compatibly with the old V17 firmware Contribution: Ed Chim <ed_chim@adaptec.com> Gilbert Wu <gilbert_wu@adaptec.com> Change Log: 1. Use dword instead of qword to display the value of Connection State register for debug purpose. 2. There are some registers location of AIC94xx chip has been changed according to the new V28 firmware. The patch has redefined the register location and provided initialization. 3. The new sequencer firmware v28 for Aic94xx SAS/SATA Linux open source device driver can be downloaded from http://www.adaptec.com/NR/exeres/35B611BC-9789-4B5B-82C6-85A2CCA8A46A.htm Signed-off-by: Gilbert Wu <gilbert_wu@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-01-13[SCSI] aic94xx: Lock DDB read/write accessesDarrick J. Wong
Extend the use of the DDB lock to include all DDB accesses, because DDB updates now occur from multiple threads. This fixes the SMP timeout problems that we were occasionally seeing with a x260, because the controller got confused when the DDBs got corrupted. Signed-off-by: Darrick J.

2007-01-13[SCSI] aic94xx: Fix DDB and SCB initializationDarrick J. Wong
Ed Chim of Adaptec informs us that the DDB registers need to be zeroed at initialization time and that some SCB initializations need to happen even if we don't use the SCB. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-01-13[SCSI] aic94xx: Match request_firmware with release_firmwareDarrick J. Wong
The vmalloc() blob holding the sequencer firmware wasn't being released at module unload time, which resulted in a memory leak. Signed-off-by: Alexis Bruemmer <alexisb@us.ibm.com> Acked-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-11-09[SCSI] aic94xx SCSI timeout fixmalahal@us.ibm.com
The patch updates DDB0 in the aic94xx driver itself. It doesn't supply or use lldd_port_formed field. DDB0 is updated prior to posting notification to libsas layer. Signed-off-by: Malahal Naineni <malahal@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
