2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2025-10-02ASoC: SOF: ipc4-pcm: fix start offset calculation for chain DMAKai Vehmanen
Assumption that chain DMA module starts the link DMA when 1ms of data is available from host is not correct. Instead the firmware chain DMA module fills the link DMA with initial buffer of zeroes and the host and link DMAs are started at the same time. This results in a small error in delay calculation. This can become a more severe problem if host DMA has delays that exceed 1ms. This results in negative delay to be calculated and bogus values reported to applications. This can confuse some applications like alsa_conformance_test. Fix the issue by correctly calculating the firmware chain DMA preamble size and initializing the start offset to this value.

Fix an issue detected by the Smatch tool: sound/soc/sof/ipc4-pcm.c: sof_ipc4_pcm_dai_link_fixup_rate() error: uninitialized symbol 'be_rate'. The warning highlights a case where `be_rate` could remain uninitialized if `num_input_formats` is zero, which would cause undefined behavior when setting `rate->min` and `rate->max` based on `be_rate`. To address this issue, a `WARN_ON_ONCE(!num_input_formats)` check was added to ensure `num_input_formats` is greater than zero. If this condition fails, the function returns `-EINVAL`, preventing the use of an uninitialized `be_rate`. This change improves the robustness of the function by catching an invalid state early and providing better feedback during development.

2024-03-25ASoC: SOF: ipc4-pcm: Correct the delay calculationPeter Ujfalusi
This patch improves the delay calculation by relying on the LLP (Linear Link Position) on the DAI side and the LDP (Linear Data Pointer) on the host side. The LDP provides the same DMA position as LPIB, but with a linear count instead of a position in the ALSA ring buffer. The LDP values are provided in bytes and must be converted to frames. The difference in units means that the host counter will wrap earlier than the LLP. We need to wrap the LLP at the same boundary as the host counter. The ASoC framework relies on separate pointer and delay callback. Measurement errors can be reduced by processing all the counter values in the pointer callback. The delay value is stored, and will be reported to higher levels in the delay callback. For playback, the firmware provides a stream_start offset to handle mixing/pause usages, where the DAI might have started earlier than the PCM device. The delay calculation must be special-cased when the link counter has not reached the start offset value, i.e. no valid audio has left the DSP.

2024-02-21ASoC: Intel: avs: Fixes and new platforms supportMark Brown
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: The avs-driver continues to be utilized on more recent Intel machines. As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality from previous platforms: SKL <- APL <- CNL <- ICL <- TGL rather than putting everything into a single file, the platform-specific bits are split into cnl/icl/tgl.c files instead. Makes the division clear and code easier to maintain. Layout of the patchset: First are two changes combined together address the sound-clipping problem, present when only one stream is running - specifically one CAPTURE stream. Follow up is naming-scheme adjustment for some of the existing functions what improves code incohesiveness. As existing IPC/IRQ code operates solely on cAVS 1.5 architecture, it needs no abstraction. The situation changes when newer platforms come into the picture. Thus the next two patches abstract the existing IPC/IRQ handlers so that majority of the common code can be re-used. The ICCMAX change stands out a bit - the AudioDSP firmware loading procedure differs on ICL-based platforms (and onwards) and having a separate commit makes the situation clear to the developers who are going to support the solution from LTS perspective. For that reason I decided not to merge it into the commit introducing the icl.c file.
2024-02-13ASoC: SOF: ipc4-pcm: fix dma_id for CHAIN_DMA capturePierre-Louis Bossart
The existing code uses (stream_tag - 1) for the host and link dma id. This is correct for playback, but for capture this results in an invalid dma_type being used. The firmware assumes that the dma_id for capture is always larger than DAI_NUM_HDA_OUT This patch adds the offset for num_playback_streams, filled on Intel platforms with the value extracted from the hardware capabilities.

2024-02-13ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspendPeter Ujfalusi
When the system is suspended while audio is active, the sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during suspend the DSP is turned off, streams will be re-started after resume. If the firmware crashes during while audio is running (or when we reset the stream before suspend) then the sof_ipc4_set_multi_pipeline_state() will fail with IPC error and the state change is interrupted. This will cause misalignment between the kernel and firmware state on next DSP boot resulting errors returned by firmware for IPC messages, eventually failing the audio resume. On stream close the errors are ignored so the kernel state will be corrected on the next DSP boot, so the second boot after the DSP panic. If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then state parameter is SOF_IPC4_PIPE_RESET and only in this case. Treat a forced pipeline reset similarly to how we treat a pcm_free by ignoring error on state sending to allow the kernel's state to be consistent with the state the firmware will have after the next boot.

2023-09-15ASoC: SOF: ipc4-pcm: fixup dailink based on copier formatBard Liao
When a copier exposes a single format, we can fixup the BE dailink with that format. This is helpful when some codec have format restrictions and e.g. don't support a 32-bit format. In that case, the copier output formats mirror that restriction in the topology file. An alternate solution was suggested earlier using a dedicated topology token. When specified, the token would be used to fix-up the dailink. The main reason why this solution was chosen is that there is a risk of a disconnect between token definition and copier format. With a single piece of information as suggested in this patch, there are fewer risks of a bad configuration.

2023-05-15ASoC: SOF: ipc4-pcm: reset all pipelines during FE DAI hw_freeRanjani Sridharan
Do not reset pipelines during the stop/suspend triggers in the BE DAI ops as the BE DAI pipeline needs to be left in the PAUSED state. It should only be reset during hw_free. This simplification is already done for the FE pipelines and the DAI trigger only toggles the states between PAUSED and RUNNING. But because the FE DAI hw_free is invoked first and all the pipelines are freed during this op, we need to make sure that the BE DAI pipeline also gets reset before it is freed. So do not skip the pipelines that have the skip_during_fe_trigger flag set when resetting pipelines. Also, because the pipeline state changes are split between the FE and BE DAI ops now, protect the BE DAI pipeline state changes with the pipeline_state_mutex as well.

2023-04-20ASoC: SOF: pcm: Add an option to skip platform trigger during stopRanjani Sridharan
In the case of IPC4, a pipeline is only paused during STOP/PAUSE/SUSPEND triggers and the FW keeps the host DMA running when a pipeline is paused. The start/stop tests iterate through STOP/START triggers without involving a hw_free. This means that the pipeline state will only toggle between PAUSED (during the STOP trigger) and RUNNING (during the START trigger). So this test should be treated in the same way as a PAUSE_PUSH/PAUSE_RELEASE test and the DMA should be kept running when toggling the pipeline states between PAUSED and RUNNING. Since there is no way to tell if a STOP trigger will be followed by hw_free or not, this patch proposes to always skip DMA stop during the STOP trigger and handle it later during hw_free. Introduce a new flag in struct sof_ipc_pcm_ops, delayed_platform_trigger, that will be used to ensure that the host DMA will not be stopped during the STOP/PAUSE/RELEASE triggers and set it for IPC4. The platform_trigger call to stop the DMA will be invoked during PCM hw_free instead when the pipeline is reset.

2023-03-22ASoC: SOF: pcm: Improve the pcm trigger sequenceRanjani Sridharan
The recommended sequence for triggering the host DMA is to first program the DMA in the FW before setting the RUN bit to start the stream in the host. With IPC3, this sequence is honored because the FW programs the DMA when the HW_PARAMS IPC is sent during PCM hw_params and then the host sets the RUN bit during sof_pcm_trigger(). But with IPC4, sof_pcm_trigger() sends the SET_PIPELINE_STATE IPC to program the DMA in the FW after the DMA RUN bit is set. In order to minimize the impact for IPC3, introduce a new flag as part of struct sof_ipc_pcm_ops, ipc_first_on_start, which will be set for IPC4 only. With this flag set, the SET_PIPELINE_STATE IPC will be sent before the DMA RUN bit is set by the host during the START/PAUSE_RELEASE triggers.

2023-03-21ASoC: SOF: ipc4/intel: Add support for chained DMAJyri Sarha
Add logic for setting up and tearing down chained DMA connections. Since pipelines are not used, all the logic to set the pipeline states can be bypassed, with only the DMA programming sequences remaining. In addition the same format needs to be used for host- and link-DMA, without the usual fixup to use the S32_LE format on the link. Note however that for convenience and compatibility with existing definitions, the topology relies on the concept of pipelines with a 'USE_CHAIN_DMA' token indicating that all the logic shall be bypassed. Unlike 'normal' ALSA sequences, the chain DMA is not programmed in hw_params/hw_free. The IPC message to set-up and tear-down chained DMA are sent in sof_ipc4_trigger_pipelines(), but the contents prepared earlier. Chained DMA is only supported by the Intel HDA DAI for now, and only S16_LE and S32_LE formats are supported for now.
