From last patch:

---- 8< ----
Currently this promise is implemented by grepping whole rf_info output for "HW" and "SW" strings. But this won't work ok in the presence of multiple CPRI devices. Imagine, for example if one device has CPRI lock, while the other does not:

PCIe CPRI /dev/sdr2@1:
  Hardware ID: 0x4b12
  DNA: [0x0048248a334a7054]
  Serial: ''
  FPGA revision: 2023-06-23  10:05:24
  FPGA vccint: 0.98 V
  FPGA vccaux: 1.76 V
  FPGA vccbram: 0.98 V
  FPGA temperature: 71.9 °C
  Clock tune: 0.0 ppm
  NUMA: 0
  CPRI_option: '5' (x8) lock=no                     <-- NOTE
  DMA0: TX fifo: 66.67us  Usage=16/32768 (0%)
  DMA0: RX fifo: 66.67us  Usage=16/32768 (0%)
  DMA0 Underflows: 0
  DMA0 Overflows: 0
PCIe CPRI /dev/sdr3@1:
  Hardware ID: 0x4b12
  DNA: [0x0048248a334a7054]
  Serial: ''
  FPGA revision: 2023-06-23  10:05:24
  FPGA vccint: 0.98 V
  FPGA vccaux: 1.77 V
  FPGA vccbram: 0.98 V
  FPGA temperature: 71.7 °C
  Clock tune: 0.0 ppm
  NUMA: 0
  CPRI_option: '5' (x8) lock=HW+SW rx/tx=46.606us   <-- NOTE
    Port #0: T14=46.606us
  DMA0: TX fifo: 66.67us  Usage=16/32768 (0%)
  DMA0: RX fifo: 66.67us  Usage=16/32768 (0%)
  DMA0 Underflows: 0
  DMA0 Overflows: 0

the old code would still report "CPRI locked all ok" and also globally without indicating which CPRI channel is locked.

-> Fix it by adjusting check_cpri_lock to parse rf_info text more precisely, detect devices there and to understand which device has CPRI lock and which does not.

For now this change is accompanied by the following change in ors-amarisoft SR to keep it working:

The way rf_info text is parsed could be also useful in the future to e.g. detect FPGA revision of the boards and report their recency status via promise.
