crypto: qat - fix ring to service map for QAT GEN4

2025-08-28T14:26:12Z

commit a238487f7965d102794ed9f8aff0b667cd2ae886 upstream. The 4xxx drivers hardcode the ring to service mapping. However, when additional configurations where added to the driver, the mappings were not updated. This implies that an incorrect mapping might be reported through pfvf for certain configurations. Add an algorithm that computes the correct ring to service mapping based on the firmware loaded on the device.

Differs from upstream as the ring to service mapping is hardcoded rather than being dynamically computed.] Reviewed-by: Ahsan Atta Tested-by: Ahsan Atta Signed-off-by: Giovanni Cabiddu Signed-off-by: Greg Kroah-Hartman

crypto: qat - fix seq_file position update in adf_ring_next()

2025-08-15T10:05:04Z

[ Upstream commit 6908c5f4f066a0412c3d9a6f543a09fa7d87824b ] The `adf_ring_next()` function in the QAT debug transport interface fails to correctly update the position index when reaching the end of the ring elements. This triggers the following kernel warning when reading ring files, such as /sys/kernel/debug/qat_c6xx_/transport/bank_00/ring_00: [27725.022965] seq_file: buggy .next function adf_ring_next [intel_qat] did not update position index Ensure that the `*pos` index is incremented before returning NULL when after the last element in the ring is found, satisfying the seq_file API requirements and preventing the warning.
