Also, if neither SCSI pass-through nor iSCSI will be used rebuilding the kernel tree can be skipped entirely. The patch below updates the qla2x00t howto accordingly, and also implements the following changes: - Fix everything the W3C HTML validator complains about: - Add DOCTYPE declaration. - Add charset declaration. - Change </br> into <br> since </br> is invalid. - Change one occurrence of & into &. - Use proper HTML constructs for numbered and unnumbered enumerations. - Use a fixed-sized font and the brown color for all computer output text (via inline CSS). - Use hyperlinks to refer to other steps. - Fix spelling errors. - Merge the Debian and non-Debian howto's because the differences are so small that it's not justified to maintain two different documents. ........ r3941 | vlnb | 2011-11-30 22:28:39 -0500 (Wed, 30 Nov 2011) | 6 lines Use get/put_unaligned_be<n>(...) instead of get/put_unaligned(cpu_to_be<n>(...)).

As an example, the get_unaligned_be24() function used in the implementation of READ_6, WRITE_6 and VERIFY_6 together with "& 0x1f0000" is inlined by the compiler and is translated as follows on an x86_64 system (2031616 equals 0x1f0000): movl 0(%r13), %r11d bswapl %r11d andl $2031616, %r11d Also eliminate a conditional branch instruction from get_trans_len_1_256().

This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files.
