Add SFF-8485 v0.7 / SAS-1 smp-write-gpio register support to libsas. Defer SAS-2 support unless/until it defines an sgpio interface. Minimum implementation needed to get the lights blinking. try_test_sas_gpio_gp_bit() provides a common method to parse the incoming write data (raw bitstream), and the to_sas_gpio_gp_bit() helper routine can be used as a basis for the set/clear operations for the 'read' implementation. Host implementations parse as many bits (ODx.[012]) as are locally supported and report the number of registers successfully written. If the submitted data overruns the internal number of registers available report the write as a success with the number of bytes remaining reported in ->resid_len. Example (assuming an active backplane) set the "identify" pattern for the first 21 devices: smp_write_gpio --count=2 --data=92,49,24,92,24,92,49,24 -t 4 --index=1 /dev/bsg/sas_hostX Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com> |
