      scsi-generic: correct error management · 89c0f643
      aurel32 提交于
      this patch allows to fully use a tape device connected to qemu through
      the scsi-generic interface.
      
      Previous patch introduced tape SCSI commands management, this one
      improve error case management:
      
      - the SCSI controller command completion must be called with the status
      value, not the sense value. In the case of scsi-generic, the SCSI status
      is given by the field status of sg_io_hdr_t (the value is left shifted
      by one regarding status codes defined in /usr/include/scsi/scsi.h)
      
      - when a read is aborted due to a mark/EOF/EOD/EOM, the len reported to
      controller can be 0. LSI controller emulation doesn't know how to manage
      this. A workaround found is to call the completion routine with
      SCSI_REASON_DONE just after calling it with SCSI_REASON_DATA with len=0.
      
      This patch also manages correctly the block size of the tape device.
      
      This patch has been tested with a real tape device "HP C5683A", linux
      guest (debian etch) and tools like "mt", "tar" and "btape".
      
      Windows guest is not better supported than before...

      i386/SVM: return amount of ASIDs · e65bdffa
      aurel32 提交于
      With SVM the TLB supports tagging to distinguish TLB entries from
      different virtual CPUs. This tag is called an ASID. The amount of ASIDs is
      given in EBX of the SVM-CPUID-leaf. Currently we return 0, which might
      break hypervisors. Let's better return something >0 here, say 0x10.
      Since we're flushing the complete TLB on every VM entry and exit we're not
      making use of the ASID information anyways.
