Add support for hardware-wrapped inline encryption keys to the Qualcomm ICE (Inline Crypto Engine) and UFS (Universal Flash Storage) drivers. I'd like these patches to be taken through the scsi tree for 6.16. But the Qualcomm / msm tree would be okay too if that is preferred. The block layer framework for this feature was merged in 6.15; refer to the "Hardware-wrapped keys" section of Documentation/block/inline-encryption.rst. This patchset wires it up for the newer Qualcomm SoCs, such as SM8650, which have a HWKM (Hardware Key Manager) and support the SCM calls needed to easily use it. Tested on the SM8650 HDK with xfstests, specifically generic/368 and generic/369, in combination with the required fscrypt patch https://lore.kernel.org/r/20250404225859.172344-1-ebiggers@xxxxxxxxxx which I plan to apply separately. Changed in v13: - Rebased onto latest upstream - Resent just the remaining driver patches For changes in v12 and earlier, see https://lore.kernel.org/r/20250210202336.349924-1-ebiggers@xxxxxxxxxx Eric Biggers (2): soc: qcom: ice: make qcom_ice_program_key() take struct blk_crypto_key ufs: qcom: add support for wrapped keys Gaurav Kashyap (1): soc: qcom: ice: add HWKM support to the ICE driver drivers/mmc/host/sdhci-msm.c | 16 +- drivers/soc/qcom/ice.c | 350 ++++++++++++++++++++++++++++++++--- drivers/ufs/host/ufs-qcom.c | 57 ++++-- include/soc/qcom/ice.h | 34 ++-- 4 files changed, 396 insertions(+), 61 deletions(-) base-commit: a52a3c18cdf369a713aca7593332bbb998c71d96 -- 2.49.0
