2025-04-21Merge patch series "scsi: qla2xxx deadcoding"Martin K. Petersen
linux@treblig.org says: Hi, This is a batch of deadcoding on the qla2xxx driver. Note the last patch removes two unused module parameters, so I guess if anyone has that in some configs somewhere that might surprise them. Other than that, it's all simple function deletion. Build tested only. Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org> Link: https://lore.kernel.org/r/20250415002803.135909-1-linux@treblig.org Signed-off-by: Martin K.

2025-04-21scsi: hisi_sas: Wait until error handling is completeYihang Li
SATA devices are lost when FLR is performed while the controller and disks are in suspended state. This is because the libata layer is called to initialize the SATA device during controller resume.

2025-04-21scsi: hisi_sas: Call I_T_nexus after soft reset for SATA diskYihang Li
In commit 21c7e972475e ("scsi: hisi_sas: Disable SATA disk phy for severe I_T nexus reset failure"), if the softreset fails upon certain conditions, the PHY connected to the disk is disabled directly. 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.

2025-04-11scsi: elx: sli4: Replace deprecated strncpy() with strscpy()Thorsten Blum
strncpy() is deprecated for NUL-terminated destination buffers; use strscpy() instead. 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.

handler On systems with a large number request slots and unavailable MCQ ESI, the current design of the interrupt handler can delay handling of other subsystems interrupts causing display artifacts, GPU stalls or system firmware requests timeouts. 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.

2025-04-11Merge patch series "Support for wrapped inline encryption keys on Qualcomm SoCs"Martin K. Petersen
Eric Biggers <ebiggers@kernel.org> says: 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.

2025-04-11scsi: soc: qcom: ice: Add HWKM support to the ICE driverGaurav Kashyap
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.

2025-04-11scsi: soc: qcom: ice: Make qcom_ice_program_key() take struct blk_crypto_keyEric Biggers
qcom_ice_program_key() currently accepts the key as an array of bytes, algorithm ID, key size enum, and data unit size. 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 <quic_gaurkash@quicinc.com> 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.

types" Kai Mäkisara <Kai.Makisara@kolumbus.fi> says: The patch set includes changes to better support different device types. The first patch fixes two obvious typos in the existing definitions. The second patch adds a device type mask to the command definitions (struct opcode_info_t). This makes possible for different command definitions for different device types and makes easy to add opcodes specific to certain device types. The mask is 32 bits wide and the bit positions are derived from the Peripheral Device Type field returned from INQUIRY and used in the struct scsi_device. In addition to the mask, the second patch adds command filtering based on device type to command queuing and building of the response in Report Supported Opcodes. The third patch splits definitions of READ(6), WRITE(6) and PRE-FETCH/READ POSITION to versions for tapes and for other devices. The fourth patch changes obtaining device type from sdebug_ptype to struct scsi_device->type whenever it is set correctly. This improves support for using different device types in the same debug host.

The "real" linux/types.h UAPI header gracefully degrades to a NOOP when included from assembly code. Mirror this behaviour in the tools/ variant. Test for __ASSEMBLER__ over __ASSEMBLY__ as the former is provided by the toolchain automatically.

2025-04-06tools/power turbostat: disable "cpuidle" invocation counters, by defaultLen Brown
Create "pct_idle" counter group, the sofware notion of residency so it can now be singled out, independent of other counter groups. Create "cpuidle" group, the cpuidle invocation counts. Disable "cpuidle", by default. Create "swidle" = "cpuidle" + "pct_idle". Undocument "sysfs", the old name for "swidle", but keep it working for backwards compatibilty. Create "hwidle", all the HW idle counters Modify "idle", enabled by default "idle" = "hwidle" + "pct_idle" (and now excludes "cpuidle") Signed-off-by: Len Brown <len.brown@intel.com>

2025-04-06Disable SLUB_TINY for build testingLinus Torvalds
... and don't error out so hard on missing module descriptions. Before commit 6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()") we used to warn about missing module descriptions, but only when building with extra warnigns (ie 'W=1'). After that commit the warning became an unconditional hard error. And it turns out not all modules have been converted despite the claims to the contrary. As reported by Damian Tometzki, the slub KUnit test didn't have a module description, and apparently nobody ever really noticed. The reason nobody noticed seems to be that the slub KUnit tests get disabled by SLUB_TINY, which also ends up disabling a lot of other code, both in tests and in slub itself. And so anybody doing full build tests didn't actually see this failre. So let's disable SLUB_TINY for build-only tests, since it clearly ends up limiting build coverage. Also turn the missing module descriptions error back into a warning, but let's keep it around for non-'W=1' builds.

2025-04-06tools/power turbostat: Increase CPU_SUBSET_MAXCPUS to 8192Justin Ernst
On systems with >= 1024 cpus (in my case 1152), turbostat fails with the error output: "turbostat: /sys/fs/cgroup/cpuset.cpus.effective: cpu str malformat 0-1151" A similar error appears with the use of turbostat --cpu when the inputted cpu range contains a cpu number >= 1024: # turbostat -c 1100-1151 "--cpu 1100-1151" malformed ... Both errors are caused by parse_cpu_str() reaching its limit of CPU_SUBSET_MAXCPUS. It's a good idea to limit the maximum cpu number being parsed, but 1024 is too low. For a small increase in compute and allocated memory, increasing CPU_SUBSET_MAXCPUS brings support for parsing cpu numbers >= 1024. Increase CPU_SUBSET_MAXCPUS to 8192, a common setting for CONFIG_NR_CPUS on x86_64. Signed-off-by: Justin Ernst <justin.ernst@hpe.com> Signed-off-by: Len Brown <len.brown@intel.com>
