Subject: [pbs-devel] [PATCH 00/11] Userspace tape driver
Date: Wed,  7 Apr 2021 12:22:57 +0200	[thread overview]
Message-ID: <20210407102308.9750-1-dietmar@proxmox.com> (raw)

This is a userspace drive implementation using SG_IO.

Why we do not use the Linux tape driver anymore, because:

- missing features (MAM, Encryption, ...)

- strange permission handling - only root (or CAP_SYS_RAWIO) can
   do SG_IO (SYS_RAW_IO)

- unability to detect EOT (you just get EIO)


Dietmar Maurer (11):
  tape: introduce trait BlockRead
  tape: introduce trait BlockWrite
  tape: implement LTO userspace driver
  tape: implement format/erase
  tape: fix LEOM handling
  tape: make fsf/bsf driver specific
  tape: make sure there is a filemark at the end of the tape
  sgutils2: add scsi_mode_sense helper
  tape: correctly set/display drive option
  tape: pmt - re-implement fsr/bsr
  tape: pmt - re-implement lock/unlock command
