firmware: cs_dsp: mock_bin: Add function to create long-offset patches

2026-01-05T13:18:28+00:00

Add cs_dsp_mock_bin_add_patch_off32(). This is the same as cs_dsp_mock_bin_add_patch() except that it puts the offset in the new 32-bit offset field and modifies the block type to indicate that it uses the long offset.

firmware: cs_dsp: mock_bin: Pass offset32 to cs_dsp_mock_bin_add_raw_block()

2026-01-05T13:18:27+00:00

Add an argument to cs_dsp_mock_bin_add_raw_block() to pass a 32-bit offset, and change the type of the existing offset argument to u16. The cs_dsp_test_bin_error.c test uses cs_dsp_mock_bin_add_raw_block() so it needs corresponding updates to pass 0 as the 32-bit offset. Version 1 and 2 of the bin file format had a 16-bit offset on blocks and the sample rate field of the blocks was not used. Version 3 adds new block types that change the old sample rate field to be a 32-bit offset with the old offset currently unused. cs_dsp_mock_bin_add_raw_block() doesn't attempt to do any magic - its purpose is to create a raw block exactly as specified by the calling test code. So the test case can pass a value for both offset fields. Signed-off-by: Richard Fitzgerald Link: https://patch.msgid.link/20251231172711.450024-5-rf@opensource.cirrus.com Signed-off-by: Mark Brown

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

2025-04-10T13:47:14+00:00

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: cs_dsp: Add mock bin file generator for KUnit testing

2024-12-13T13:14:40+00:00

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

2024-12-13T13:14:38+00:00

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

2024-12-13T13:14:37+00:00

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.
