2024-07-01tpm_tis_spi: add missing attpm20p SPI device ID entryVitor Soares
"atmel,attpm20p" DT compatible is missing its SPI device ID entry, not allowing module autoloading and leading to the following message: "SPI driver tpm_tis_spi has no spi_device_id for atmel,attpm20p" Based on: commit 7eba41fe8c7b ("tpm_tis_spi: Add missing SPI ID") Fix this by adding the corresponding "attpm20p" spi_device_id entry.

2024-07-01char: tpm: Fix possible memory leak in tpm_bios_measurements_open()Joe Hattori
In tpm_bios_measurements_open(), get_device() is called on the device embedded in struct tpm_chip. In the error path, however, put_device() is not called. This results in a reference count leak, which prevents the device from being properly released. This commit makes sure to call put_device() when the seq_open() call fails.

2024-07-01s390/sclp: Add timeout to Store Data requestsPeter Oberparleiter
Due to a bug in some firmware versions, Store Data requests might not get an event response in certain situations. As a result, the boot process will be blocked indefinitely. Fix this by introducing timeout handling for Store Data requests. In case a timeout occurs, the Store Data operation is halted and no data is retrieved from the SCLP facility. Note: A minority of installed systems rely on Store Data result for device auto-configuration. These systems will fail to boot in case of a Store Data timeout and will need to be switched to manual device configuration as workaround.

2024-07-01s390/sclp: Prevent release of buffer in I/OPeter Oberparleiter
When a task waiting for completion of a Store Data operation is interrupted, an attempt is made to halt this operation. If this attempt fails due to a hardware or firmware problem, there is a chance that the SCLP facility might store data into buffers referenced by the original operation at a later time. Handle this situation by not releasing the referenced data buffers if the halt attempt fails. For current use cases, this might result in a leak of few pages of memory in case of a rare hardware/firmware malfunction.

2024-07-01perf: imx_perf: let the driver manage the counter usage rather the userXu Yang
In current design, the user of perf app needs to input counter ID to count events. However, this is not user-friendly since the user needs to lookup the map table to find the counter. Instead of letting the user to input the counter, let this driver to manage the counters in this patch. This will be implemented by: 1. allocate counter 0 for cycle event. 2. find unused counter from 1-10 for reference events. 3. allocate specific counter for counter-specific events. In this patch, counter attr will be kept for back-compatible but all the value passed down by counter=<n> will be ignored. To mark counter-specific events, counter ID will be encoded into perf_pmu_events_attr.id.

2024-07-01firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headersRichard Fitzgerald
Check that all fields of a V2 algorithm header fit into the available firmware data buffer. The wmfw V2 format introduced variable-length strings in the algorithm block header. This means the overall header length is variable, and the position of most fields varies depending on the length of the string fields. Each field must be checked to ensure that it does not overflow the firmware data buffer. As this ia bugfix patch, the fixes avoid making any significant change to the existing code. This makes it easier to review and less likely to introduce new bugs.

2024-07-01firmware: cs_dsp: Fix overflow checking of wmfw headerRichard Fitzgerald
Fix the checking that firmware file buffer is large enough for the wmfw header, to prevent overrunning the buffer. The original code tested that the firmware data buffer contained enough bytes for the sums of the size of the structs wmfw_header + wmfw_adsp1_sizes + wmfw_footer But wmfw_adsp1_sizes is only used on ADSP1 firmware. For ADSP2 and Halo Core the equivalent struct is wmfw_adsp2_sizes, which is 4 bytes longer. So the length check didn't guarantee that there are enough bytes in the firmware buffer for a header with wmfw_adsp2_sizes. This patch splits the length check into three separate parts. Each of the wmfw_header, wmfw_adsp?_sizes and wmfw_footer are checked separately before they are used.

2024-07-01HID: bpf: add a driver for the Huion Inspiroy 2S (H641P)Benjamin Tissoires
This is a a driver for the Huion Inspiroy 2S in both modes (firmware mode and tablet mode). This device has 6 buttons and a wheel, all of which send key combinations (see the comments for the defaults). Luckily the device is quite limited in that it only supports one button down at a time, so with this BPF we can simply remap the 8 possible report IDs to our own custom-built report descriptor. If the device is in tablet mode (e.g. using huion-switcher it sends everything through the vendor report instead). This BPF program converts both, depending which devices you attach to you get both. Or if you attach to all hid devices you get a duplicate device but it'll work either way. This BPF should be mostly compatible for the M and L as well though they have more buttons so the rdescs will need some minor rework.

2024-07-01HID: bpf: Add a HID report composition helper macrosBenjamin Tissoires
These macros make it slightly easier and more modular to create a HID report descriptor from scratch. Since they carry the annotation we don't need to comment it and they cannot get stale. For comparison, before we had this: 0x15, 0x00, // Logical Minimum (0) 0x25, 0x01, // Logical Maximum (1) 0x95, 0x04, // Report Count (4) 0x75, 0x01, // Report Size (1) Now we can write this as: LogicalRange_i8(0, 1) ReportCount(4) ReportSize(1) Because these macros are for creating new report descriptors, some bits aren't directly exposed. e.g in the example above: there is a logical range as one macro that sets both min and max. There is seldom a good use case for skipping either anyway. These macros will need to be expanded over time. For Usage Pages and Usage IDs, we use a tool to parse the HUT JSON (attached to the HUT 1.5 PDF [1]) and generate all #defines for all usage pages and usages in the form: #define UsagePage_Foo_Bar #define Usage_FB_SomeOrOther Where the FB is simply the acronym based on the capital letters in the Usage Page name or the first three letters, whichever makes slightly more sense.

2024-07-01HID: bpf: fix gcc warning and unify __u64 into u64Benjamin Tissoires
I've got multiple reports of: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]. Let's use the same trick than kernel/bpf/helpers.c to shut up that warning. Even if we were on an architecture with addresses on more than 64 bits, this isn't much of an issue as the address is not used as a pointer, but as an hash and the caller is not supposed to go back to the kernel address ever. And while we change those, make sure we use u64 instead of __u64 for consistency Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202406280633.OPB5uIFj-lkp@intel.com/ Closes: https://lore.kernel.org/oe-kbuild-all/202406282304.UydSVncq-lkp@intel.com/ Closes: https://lore.kernel.org/oe-kbuild-all/202406282242.Fk738zzy-lkp@intel.com/ Reported-by: Mirsad Todorovac <mtodorovac69@gmail.com> Fixes: 67eccf151d76 ("HID: add source argument to HID low level functions") Link: https://patch.msgid.link/20240701-fix-cki-v2-2-20564e2e1393@kernel.org Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>

2024-07-01RDMA/mlx5: Support plane device and driver APIs to add and delete itMark Zhang
This patch supports driver APIs "add_sub_dev" and "del_sub_dev", to add and delete a plane device respectively. A mlx5 plane device is a rdma SMI device; It provides the SMI capability through user MAD for it's parent, the logical multi-plane aggregated device. For a plane port: - It supports QP0 only; - When adding a plane device, all plane ports are added; - For some commands like mad_ifc, both plane_index and native portnum is needed; - When querying or modifying a plane port context, the native portnum must be used, as the query/modify_hca_vport_context command doesn't support plane port.

This patch adds 2 APIs, as well as driver operations to support adding and deleting an IB sub device, which provides part of functionalities of it's parent. A sub device has a type; for a sub device with type "SMI", it provides the smi capability through umad for its parent, meaning uverb is not supported. A sub device cannot live without a parent. So when a parent is released, all it's sub devices are released as well.

2024-07-01spi: davinci: Unset POWERDOWN bit when releasing resourcesBastien Curutchet
On the OMAPL138, the SPI reference clock is provided by the Power and Sleep Controller (PSC). The PSC's datasheet says that 'some peripherals have special programming requirements and additional recommended steps you must take before you can invoke the PSC module state transition'. I didn't find more details in documentation but it appears that PSC needs the SPI to clear the POWERDOWN bit before disabling the clock. Indeed, when this bit is set, the PSC gets stuck in transitions from enable to disable state.
