However both callers have a struct blk_crypto_key which contains all that information. Thus they both have similar code that converts the blk_crypto_key into the form that qcom_ice_program_key() wants. Once wrapped key support is added, the key type would need to be added to the arguments too. Therefore, this patch changes qcom_ice_program_key() to take in all this information as a struct blk_crypto_key directly. The calling code is updated accordingly. This ends up being much simpler, and it makes the key type be passed down automatically once wrapped key support is added. Based on a patch by Gaurav Kashyap that replaced the byte array argument only. This patch makes the blk_crypto_key replace other arguments like the algorithm ID too, ensuring that there remains only one source of truth.

From 7cc6e0c34b21b6e981afde695132f38e174c7aa5 Mon Sep 17 00:00:00 2001 From: Gaurav Kashyap Date: Fri, 4 Apr 2025 16:15:31 -0700 Subject: [PATCH 07/77] scsi: soc: qcom: ice: Add HWKM support to the ICE driver Qualcomm's Inline Crypto Engine (ICE) version 3.2 and later includes a key management hardware block called the Hardware Key Manager (HWKM). Add support for HWKM to the ICE driver. HWKM provides hardware-wrapped key support where the ICE (storage) keys are not exposed to software and instead are protected in hardware. Later patches will wire up this feature to ufs-qcom and sdhci-msm using the support added in this patch. HWKM and legacy mode are currently mutually exclusive. The selection of which mode to use has to be made before the storage driver(s) registers any inline encryption capable disk(s) with the block layer (i.e., generally at boot time) so that the appropriate crypto capabilities can be advertised to upper layers. Therefore, make the ICE driver select HWKM mode when the all of the following are true: - The new module parameter qcom_ice.use_wrapped_keys=1 is specified. - HWKM is present and is at least v2, i.e. ICE is v3.2.1 or later. - The SCM calls needed to fully use HWKM are supported by TrustZone. [EB: merged related patches; fixed the module parameter to work correctly; dropped unnecessary support for HWKM v1; fixed error handling; improved log messages, comments, and commit message; fixed naming; merged enable and init functions; and other cleanups] Signed-off-by: Gaurav Kashyap Signed-off-by: Bartosz Golaszewski Co-developed-by: Eric Biggers Signed-off-by: Eric Biggers Link: https://lore.kernel.org/r/20250404231533.174419-3-ebiggers@kernel.org Acked-by: Ulf Hansson # For MMC Signed-off-by: Martin K.

Since the interrupt routine can take quite some time, it's preferable to move it to a threaded handler and leave the hard interrupt handler wake up the threaded interrupt routine, the interrupt line would be masked until the processing is finished in the thread thanks to the IRQS_ONESHOT flag. When MCQ & ESI interrupts are enabled the I/O completions are now directly handled in the "hard" interrupt routine to keep IOPs high since queues handling is done in separate per-queue interrupt routines. This fixes all encountered issued when running FIO tests on the Qualcomm SM8650 platform.

Since sli_config_cmd_init() already zeroes out the destination buffers, the potential NUL-padding by strncpy() is unnecessary. strscpy() copies only the required characters and guarantees NUL-termination. And since all three destination buffers have a fixed length, strscpy() automatically determines their size using sizeof() when the argument is omitted. This makes any explicit sizeof() calls unnecessary. The source strings are also NUL-terminated and meet the __must_be_cstr() requirement of strscpy(). No functional changes intended.

Manual recovery is required, which is inconvenient for users in actual use. In addition, SATA disks do not support simultaneous connection of multiple hosts. Therefore, when multiple controllers are connected to a SATA disk at the same time, the controller which is connected later failed to issue an ATA softreset to the SATA disk. As a result, the PHY associated with the disk is disabled and cannot be automatically recovered. Now that, we will not focus on the execution result of softreset. No matter whether the execution is successful or not, we will directly carry out I_T_nexus_reset.

(Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct crb_addr_pair *" and the returned type will be a _different_ "struct crb_addr_pair *", causing a warning.

This moves the values to a per CPU counter. Combined with the per CPU stats patch, this improves IOPS by up to 33% for 8K IOS when using 4 or more queues from the initiator.
