firmware: cs_dsp: test_bin_error: Fix uninitialized data used as fw version

2025-04-25T08:50:49Z

[ Upstream commit 285b2c74cf9982e873ef82a2cb1328d9e9406f65 ] Call cs_dsp_mock_xm_header_get_fw_version() to get the firmware version from the dummy XM header data in cs_dsp_bin_err_test_common_init(). Make the same change to cs_dsp_bin_test_common_init() and remove the cs_dsp_mock_xm_header_get_fw_version_from_regmap() function. The code in cs_dsp_test_bin.c was correctly calling cs_dsp_mock_xm_header_get_fw_version_from_regmap() to fetch the fw version from a dummy header it wrote to XM registers. However in cs_dsp_test_bin_error.c the test doesn't stuff a dummy header into XM, it populates it the normal way using a wmfw file. It should have called cs_dsp_mock_xm_header_get_fw_version() to get the data from its blob buffer, but was calling cs_dsp_mock_xm_header_get_fw_version_from_regmap(). As nothing had been written to the registers this returned the value of uninitialized data. The only other use of cs_dsp_mock_xm_header_get_fw_version_from_regmap() was cs_dsp_test_bin.c, but it doesn't need to use it. It already has a blob buffer containing the dummy XM header so it can use cs_dsp_mock_xm_header_get_fw_version() to read from that.

firmware: qcom: scm: add calls for wrapped key support

2025-01-08T23:11:07Z

Add helper functions for the SCM calls required to support hardware-wrapped inline storage encryption keys. These SCM calls manage wrapped keys via Qualcomm's Hardware Key Manager (HWKM), which can only be accessed from TrustZone. QCOM_SCM_ES_GENERATE_ICE_KEY and QCOM_SCM_ES_IMPORT_ICE_KEY create a new long-term wrapped key, with the former making the hardware generate the key and the latter importing a raw key. QCOM_SCM_ES_PREPARE_ICE_KEY converts the key to ephemerally-wrapped form so that it can be used for inline storage encryption. These are planned to be wired up to new ioctls via the blk-crypto framework; see the proposed documentation for the hardware-wrapped keys feature for more information. Similarly there's also QCOM_SCM_ES_DERIVE_SW_SECRET which derives a "software secret" from an ephemerally-wrapped key and will be wired up to the corresponding operation in the blk_crypto_profile. These will all be used by the ICE driver in drivers/soc/qcom/ice.c.

firmware: cs_dsp: Add mock bin file generator for KUnit testing

2024-12-13T13:14:40Z

Add a mock firmware file that emulates what the firmware build tools would normally create. This will be used by KUnit tests to generate a test bin file. The data payload in a bin is an opaque blob, so the mock bin only needs to generate the appropriate file header and description block for each payload blob.

firmware: cs_dsp: Add mock DSP memory map for KUnit testing

2024-12-13T13:14:38Z

Add helper functions to implement an emulation of the DSP memory map. There are three main groups of functionality: 1. Define a mock cs_dsp_region table. 2. Calculate the addresses of memory and algorithms from the firmware header in XM. 3. Build a mock XM header in emulated XM.

firmware: cs_dsp: Add mock regmap for KUnit testing

2024-12-13T13:14:37Z

Add a mock regmap implementation to act as a simulated DSP for KUnit testing. This is built as a utility module so that it could be used by clients of cs_dsp to create a mock "DSP" for their own testing. cs_dsp interacts with the DSP only through registers. Most of the register space of the DSP is RAM. ADSP cores have a small set of control registers. HALO Core DSPs have a much larger set of control registers but only a small subset are used. Most writes are "blind" in the sense that cs_dsp does not expect to receive any sort of response from the DSP. So there isn't any need to emulate a "DSP", only a set of registers that can be written and read back. The idea of the mock regmap is to use the cache to accumulate writes which can then be tested against the values that are expected to be in the registers. Stray writes can be detected by dropping the cache entries for all addresses that should have been written and then issuing a regcache_sync(). If this causes bus writes it means there were writes to unexpected registers.

A few more Qualcomm driver updates for v6.13 Make the Adreno driver invoke the SMMU aperture setup firmware function, which is required to allow the GPU to manage per-process page tables in some firmware versions - as an example Rb3Gen2 has no GPU without this. Add X1E Devkit to the list of devices that has functional EFI variable access through the uefisecapp. Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver, as this only applies to a single platform, and introduce support for QCS8300, QCS615, SAR2130P, and SAR1130P. Lastly, add IPQ5424 and IPQ5404 to the Qualcomm socinfo driver. * tag 'qcom-drivers-for-6.13-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: ice: Remove the device_link field in qcom_ice drm/msm/adreno: Setup SMMU aparture for per-process page table firmware: qcom: scm: Introduce CP_SMMU_APERTURE_ID soc: qcom: socinfo: add IPQ5424/IPQ5404 SoC ID dt-bindings: arm: qcom,ids: add SoC ID for IPQ5424/IPQ5404 soc: qcom: llcc: Flip the manual slice configuration condition dt-bindings: firmware: qcom,scm: Document sm8750 SCM firmware: qcom: uefisecapp: Allow X1E Devkit devices soc: qcom: llcc: Add LLCC configuration for the QCS8300 platform dt-bindings: cache: qcom,llcc: Document the QCS8300 LLCC soc: qcom: llcc: Add configuration data for QCS615 dt-bindings: cache: qcom,llcc: Document the QCS615 LLCC soc: qcom: llcc: add support for SAR2130P and SAR1130P soc: qcom: llcc: use deciman integers for bit shift values dt-bindings: cache: qcom,llcc: document SAR2130P and SAR1130P Link: https://lore.kernel.org/r/20241113032425.356306-1-andersson@kernel.org Signed-off-by: Arnd Bergmann

firmware: qcom: scm: Introduce CP_SMMU_APERTURE_ID

2024-11-11T18:03:26Z

The QCOM_SCM_SVC_MP service provides QCOM_SCM_MP_CP_SMMU_APERTURE_ID, which is used to trigger the mapping of register banks into the SMMU context for per-processes page tables to function (in case this isn't statically setup by firmware). This is necessary on e.g. QCS6490 Rb3Gen2, in order to avoid "CP | AHB bus error"-errors from the GPU. Introduce a function to allow the msm driver to invoke this call.
