• bc7e380a6   [SCSI] tgt: fix sesnse buffer problems ... Browse Code »

  This patch simplify the way to notify LLDs of the command completion
  and addresses the following sense buffer problems:

  - can't handle both data and sense.
  - forces user-space to use aligned sense buffer

  tgt copies sense_data from userspace to cmnd->sense_buffer (if
  necessary), maps user-space pages (if necessary) and then calls
  host->transfer_response (host->transfer_data is removed).

• 930e99bd1   [SCSI] tgt: fix the user/kernel ring buffer interface ... Browse Code »

  This patches fixes two bugs in the scsi target infrastructure's
  user/kernel interface.

  - It wrongly assumes that the ring buffer size of the interface (64KB)
  is larger than or equal to the system page size. This patch sets the
  ring buffer size to PAGE_SIZE if the system page size is larger.

  - It uses PAGE_SIZE in the header file exported to userspace. This
  patch removes it.

  The user-space daemon and tgt kernel module need bi-directional
  kernel/user high-performance interface, however, mainline provides no
  standard interface like that.

  This patch adds shared memory interface between kernel and user spaces
  like some other drivers do by using own character device. The
  user-space daemon and tgt kernel module creates shared memory via mmap
  and use it like ring buffer. poll (kernel to user) and write (user to
  kernel) system calls are used for notification.
