      [SCSI] aic94xx: Increase can_queue for better performance · f19eaa7f
      Darrick J. Wong authored
      This patch sets can_queue in the aic94xx driver's scsi_host to better
      performing values than what's there currently.  It seems that
      asd_ha->seq.can_queue reflects the number of requests that can be
      queued per controller; so long as there's one scsi_host per
      controller, it seems logical that the scsi_host ought to have the same
      can_queue value.  To the best of my (still limited) knowledge, this
      method provides the correct value.
      
      The effect of leaving this value set to 1 is terrible performance in
      the case of either (a) certain Maxtor SAS drives flying solo or (b)
      flooding several disks with I/O simultaneously (md-raid).  There may be
      more scenarios where we see similar problems that I haven't uncovered.

      [SCSI] MODULE_FIRMWARE for binary firmware(s) · 187afbed
      Jon Masters authored
      Right now, various kernel modules are being migrated over to use
      request_firmware in order to pull in binary firmware blobs from userland
      when the module is loaded. This makes sense.
      
      However, there is right now little mechanism in place to automatically
      determine which binary firmware blobs must be included with a kernel in
      order to satisfy the prerequisites of these drivers. This affects
      vendors, but also regular users to a certain extent too.
      
      The attached patch introduces MODULE_FIRMWARE as a mechanism for
      advertising that a particular firmware file is to be loaded - it will
      then show up via modinfo and could be used e.g. when packaging a kernel.

        o aic94xx: add transport class phy reset capability
        o aic94xx: remove local_attached flag
        o Remove README
