2022-03-02platform/x86: Add AMD system management interfaceSuma Hegde1-0/+2
Recent Fam19h EPYC server line of processors from AMD support system management functionality via HSMP (Host System Management Port) interface. The Host System Management Port (HSMP) is an interface to provide OS-level software with access to system management functions via a set of mailbox registers. More details on the interface can be found in chapter "7 Host System Management Port (HSMP)" of the following PPR https://www.amd.com/system/files/TechDocs/55898_B1_pub_0.50.zip This patch adds new amd_hsmp module under the drivers/platforms/x86/ which creates miscdevice with an IOCTL interface to the user space. /dev/hsmp is for running the hsmp mailbox commands.

2022-03-01Merge tag 'qcom-drivers-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/driversArnd Bergmann3-0/+19
Qualcomm driver updates for v5.18 This refactors the Qualcomm mdt file loader, to partially decouple it from the SCM peripheral-authentication-service. This is needed as newer platforms, such as the Qualcomm SM8450, require the metadata to remain accessible to TrustZone during a longer time. This is followed by the introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1). It changes the way hardware version differences are handled in the LLCC driver and introduces support for Qualcomm SM8450. While updating the dt binding for LLCC it also introduces the missing SM8350 compatible. The ocmem and aoss drivers gains missing put_device() calls and rpmpd gains a missing check for kcalloc() failure. The SPM driver is updated to avoid instantiating the SPM cpuidle devices if the CPUs aren't controlled by SPM, such as when Snapdragon 8916 operates in 32-bit mode without PSCI. The RPM power-domain driver gains MSM8226 support. Lastly the socinfo driver gains knowledge about a few new SoCs and PMICs. * tag 'qcom-drivers-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (37 commits) soc: qcom: rpmpd: Add MSM8226 support dt-bindings: power: rpmpd: Add MSM8226 to rpmpd binding soc: qcom: mdt_loader: Fix split-firmware condition dt-bindings: arm: msm: Add LLCC compatible for SM8450 dt-bindings: arm: msm: Add LLCC compatible for SM8350 soc: qcom: llcc: Add configuration data for SM8450 SoC soc: qcom: llcc: Update register offsets for newer LLCC HW soc: qcom: llcc: Add missing llcc configuration data soc: qcom: llcc: Add write-cache cacheable support soc: qcom: llcc: Update the logic for version info extraction soc: qcom: llcc: Add support for 16 ways of allocation soc: qcom: socinfo: Add some more PMICs and SoCs firmware: qcom: scm: Add support for MC boot address API firmware: qcom: scm: Drop cpumask parameter from set_boot_addr() firmware: qcom: scm: Simplify set_cold/warm_boot_addr() cpuidle: qcom-spm: Check if any CPU is managed by SPM remoteproc: qcom: pas: Add SM8450 remoteproc support dt-bindings: remoteproc: qcom: pas: Add SM8450 PAS compatibles remoteproc: qcom: pas: Carry PAS metadata context soc: qcom: mdt_loader: Extract PAS operations ...

IPQ8074 adds description of GIVv2m and SMEM, and ensures that TrustZone related memory is reserved from Linux. On the Snapdragon 7c Gen 3 (SC7280) description of display, displayport, L3 interconnect, bluetooth, CPU opp-tables are added. Another revision of the Google Herobrine is introduced and a bunch of cleanups are introduced. On Snapdragon 845 new support for the SHIFT6mq device is introduced, the OnePlus devices gains fuel gauge and the platform gains GSI DMA support, which is enabled for SPI (for now). On the Snapdragon 850 based WindowsOnSnapdragon laptops, initial support for Samsugn Galaxy Book2 is introduced and the Lenovo Yoga C630 gains description of its backlight controls. The Snapdragon 625 platform (MSM8953) the thereof derrived Snapdragon 632 platform is introduced, with initial description of the Fairphone 3. Fairphone 4 on the SM7225 platform gains proper WLED configuration. On Snapdragon 855 (SM8150) description of the limits hardware (LMh) is introduced and the SPI and I2C devices are wired to the GSI DMA controller. On Snapdragon 865 (SM8250) the CPU and cluster idle states are introduced, the MSI interrupts for PCIe 1 and 2 are corrected and the CPUfreq driver gains knowledge about thermal pressure interrupts. On Snapdragon 8 Gen 1 (SM8450) LLCC, interconnect and remoteproc descriptions are added. The SM8450 Hardware Development Kit is introduced and the QRD has its remoteproc instances enabled. Cluster idle and RPMh parameters are corrected on SM8150, SM8350 and SM8540. The IPA device on SC7180, SC7280 and SM8350 gains knowledge of the AOSS QMP mailbox, allowing it to enable retention of IPA registers during power collapse. DeviceTree validation issues related to thermal zone naming, missing CPU, device and platform compatibles, APR, Google EC PWM, DB410c sound, QCS404 opp-tables and SM8250 PCIe nodes are corrected.

2022-02-28of: unittest: add program to process EXPECT messagesFrank Rowand1-3/+24
If unittest detects a problem it will print a warning or error message to the console. Unittest also triggers warning and error messages from other kernel code as a result of intentionally bad unittest data. This has led to confusion as to whether the triggered messages are an expected result of a test or whether there is a real problem that is independent of unittest. EXPECT messages were added to unittest to report each triggered message that is expected, resulting in verbose console output. scripts/dtc/of_unittest is a new program that processes the EXPECT messages to determine whether the triggered messages occurred and also removes the excess verbosity of the EXPECT messages. More information is available from 'scripts/dtc/of_unittest_expect --help'.

2022-02-28blk-crypto: show crypto capabilities in sysfsEric Biggers1-0/+49
Add sysfs files that expose the inline encryption capabilities of request queues: /sys/block/$disk/queue/crypto/max_dun_bits /sys/block/$disk/queue/crypto/modes/$mode /sys/block/$disk/queue/crypto/num_keyslots Userspace can use these new files to decide what encryption settings to use, or whether to use inline encryption at all. This also brings the crypto capabilities in line with the other queue properties, which are already discoverable via the queue directory in sysfs. Design notes: - Place the new files in a new subdirectory "crypto" to group them together and to avoid complicating the main "queue" directory. This also makes it possible to replace "crypto" with a symlink later if we ever make the blk_crypto_profiles into real kobjects (see below). - It was necessary to define a new kobject that corresponds to the crypto subdirectory. For now, this kobject just contains a pointer to the blk_crypto_profile. Note that multiple queues (and hence multiple such kobjects) may refer to the same blk_crypto_profile. An alternative design would more closely match the current kernel data structures: the blk_crypto_profile could be a kobject itself, located directly under the host controller device's kobject, while /sys/block/$disk/queue/crypto would be a symlink to it. I decided not to do that for now because it would require a lot more changes, such as no longer embedding blk_crypto_profile in other structures, and also because I'm not sure we can rule out moving the crypto capabilities into 'struct queue_limits' in the future. (Even if multiple queues share the same crypto engine, maybe the supported data unit sizes could differ due to other queue properties.) It would also still be possible to switch to that design later without breaking userspace, by replacing the directory with a symlink. - Use "max_dun_bits" instead of "max_dun_bytes". Currently, the kernel internally stores this value in bytes, but that's an implementation detail. It probably makes more sense to talk about this value in bits, and choosing bits is more future-proof. - "modes" is a sub-subdirectory, since there may be multiple supported crypto modes, sysfs is supposed to have one value per file, and it makes sense to group all the mode files together. - Each mode had to be named. The crypto API names like "xts(aes)" are not appropriate because they don't specify the key size. Therefore, I assigned new names. The exact names chosen are arbitrary, but they happen to match the names used in log messages in fs/crypto/. - The "num_keyslots" file is a bit different from the others in that it is only useful to know for performance reasons. However, it's included as it can still be useful. For example, a user might not want to use inline encryption if there aren't very many keyslots.
