[PATCH v2 0/2] ASoC: SOF: Correct sps->stream and cstream nullity management

by Peter Ujfalusi

Hi, Changes since v1: - Cc stable The nullity of sps->cstream needs to be checked in sof_ipc_msg_data() and not assume that it is not NULL. The sps->stream must be cleared to NULL on close since this is used as a check to see if we have active PCM stream.

[PATCH] ASoC: SOF: ipc4-topology: Harden loops for looking up ALH copiers

by Peter Ujfalusi

Other, non DAI copier widgets could have the same stream name (sname) as the ALH copier and in that case the copier->data is NULL, no alh_data is attached, which could lead to NULL pointer dereference. We could check for this NULL pointer in sof_ipc4_prepare_copier_module() and avoid the crash, but a similar loop in sof_ipc4_widget_setup_comp_dai() will miscalculate the ALH device count, causing broken audio. The correct fix is to harden the matching logic by making sure that the 1. widget is a DAI widget - so dai = w->private is valid 2. the dai (and thus the copier) is ALH copier Fixes: 0e357b529053 ("ASoC: SOF: ipc4-topology: add SoundWire/ALH aggregation support") Cc: stable(a)vger.kernel.org Reported-by: Seppo Ingalsuo <seppo.ingalsuo(a)linux.intel.com> Link: https://github.com/thesofproject/sof/pull/9652 Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)linux.intel.com> Reviewed-by: Liam Girdwood <liam.r.girdwood(a)intel.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan(a)linux.intel.com> Reviewed-by: Bard Liao <yung-chuan.liao(a)linux.intel.com> --- sound/soc/sof/ipc4-topology.c | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/sound/soc/sof/ipc4-topology.c b/sound/soc/sof/ipc4-topology.c index b55eb977e443..70b7bfb080f4 100644 --- a/sound/soc/sof/ipc4-topology.c +++ b/sound/soc/sof/ipc4-topology.c @@ -765,10 +765,16 @@ static int sof_ipc4_widget_setup_comp_dai(struct snd_sof_widget *swidget) } list_for_each_entry(w, &sdev->widget_list, list) { - if (w->widget->sname && + struct snd_sof_dai *alh_dai; + + if (!WIDGET_IS_DAI(w->id) || !w->widget->sname || strcmp(w->widget->sname, swidget->widget->sname)) continue; + alh_dai = w->private; + if (alh_dai->type != SOF_DAI_INTEL_ALH) + continue; + blob->alh_cfg.device_count++; } @@ -2061,11 +2067,13 @@ sof_ipc4_prepare_copier_module(struct snd_sof_widget *swidget, list_for_each_entry(w, &sdev->widget_list, list) { u32 node_type; - if (w->widget->sname && + if (!WIDGET_IS_DAI(w->id) || !w->widget->sname || strcmp(w->widget->sname, swidget->widget->sname)) continue; dai = w->private; + if (dai->type != SOF_DAI_INTEL_ALH) + continue; alh_copier = (struct sof_ipc4_copier *)dai->private; alh_data = &alh_copier->data; node_type = SOF_IPC4_GET_NODE_TYPE(alh_data->gtw_cfg.node_id); -- 2.47.1

[PATCH] soc: qcom: mark pd-mapper as broken

by Johan Hovold

When using the in-kernel pd-mapper on x1e80100, client drivers often fail to communicate with the firmware during boot, which specifically breaks battery and USB-C altmode notifications. This has been observed to happen on almost every second boot (41%) but likely depends on probe order: pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125) pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125 ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125 qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications In the same setup audio also fails to probe albeit much more rarely: PDR: avs/audio get domain list txn wait failed: -110 PDR: service lookup for avs/audio failed: -110 Chris Lew has provided an analysis and is working on a fix for the ECANCELED (125) errors, but it is not yet clear whether this will also address the audio regression. Even if this was first observed on x1e80100 there is currently no reason to believe that these issues are specific to that platform. Disable the in-kernel pd-mapper for now, and make sure to backport this to stable to prevent users and distros from migrating away from the user-space service. Fixes: 1ebcde047c54 ("soc: qcom: add pd-mapper implementation") Cc: stable(a)vger.kernel.org # 6.11 Link: https://lore.kernel.org/lkml/Zqet8iInnDhnxkT9@hovoldconsulting.com/ Signed-off-by: Johan Hovold <johan+linaro(a)kernel.org> --- It's now been over two months since I reported this regression, and even if we seem to be making some progress on at least some of these issues I think we need disable the pd-mapper temporarily until the fixes are in place (e.g. to prevent distros from dropping the user-space service).

[PATCH v2] kbuild: switch from lz4c to lz4 for compression

by Parth Pancholi

From: Parth Pancholi <parth.pancholi(a)toradex.com> Replace lz4c with lz4 for kernel image compression. Although lz4 and lz4c are functionally similar, lz4c has been deprecated upstream since 2018. Since as early as Ubuntu 16.04 and Fedora 25, lz4 and lz4c have been packaged together, making it safe to update the requirement from lz4c to lz4. Consequently, some distributions and build systems, such as OpenEmbedded, have fully transitioned to using lz4. OpenEmbedded core adopted this change in commit fe167e082cbd ("bitbake.conf: require lz4 instead of lz4c"), causing compatibility issues when building the mainline kernel in the latest OpenEmbedded environment, as seen in the errors below. This change also updates the LZ4 compression commands to make it backward compatible by replacing stdin and stdout with the '-' option, due to some unclear reason, the stdout keyword does not work for lz4 and '-' works for both. In addition, this modifies the legacy '-c1' with '-9' which is also compatible with both. This fixes the mainline kernel build failures with the latest master OpenEmbedded builds associated with the mentioned compatibility issues.

[PATCH v5 0/7] drm: Add DSI/DP support for Renesas r8a779h0 V4M and grey-hawk board

by Tomi Valkeinen

Add everything needed to support the DSI output on Renesas r8a779h0 (V4M) SoC, and the DP output (via sn65dsi86 DSI to DP bridge) on the Renesas grey-hawk board. Overall the DSI and the board design is almost identical to Renesas r8a779g0 and white-hawk board. Note: the v4 no longer has the dts and the clk patches, as those have been merged to renesas-devel. Signed-off-by: Tomi Valkeinen <tomi.valkeinen+renesas(a)ideasonboard.com> --- Changes in v5: - Add minItems/maxItems to the top level cmms & vsps properties - Drop "minItems: 1" when not needed - Link to v4: https://lore.kernel.org/r/20241213-rcar-gh-dsi-v4-0-f8e41425207b@ideasonboa… Changes in v4: - Dropped patches merged to renesas-devel - Added new patch "dt-bindings: display: renesas,du: Add missing maxItems" to fix the bindings - Add the missing maxItems to "dt-bindings: display: renesas,du: Add r8a779h0" - Link to v3: https://lore.kernel.org/r/20241206-rcar-gh-dsi-v3-0-d74c2166fa15@ideasonboa… Changes in v3: - Update "Write DPTSR only if there are more than one crtc" patch to "Write DPTSR only if the second source exists" - Add Laurent's Rb - Link to v2: https://lore.kernel.org/r/20241205-rcar-gh-dsi-v2-0-42471851df86@ideasonboa… Changes in v2: - Add the DT binding with a new conditional block, so that we can set only the port@0 as required - Drop port@1 from r8a779h0.dtsi (there's no port@1) - Add a new patch to write DPTSR only if num_crtcs > 1 - Drop RCAR_DU_FEATURE_NO_DPTSR (not needed anymore) - Add Cc: stable to the fix, and move it as first patch - Added the tags from reviews - Link to v1: https://lore.kernel.org/r/20241203-rcar-gh-dsi-v1-0-738ae1a95d2a@ideasonboa… --- Tomi Valkeinen (7): drm/rcar-du: dsi: Fix PHY lock bit check drm/rcar-du: Write DPTSR only if the second source exists dt-bindings: display: renesas,du: Add missing constraints dt-bindings: display: renesas,du: Add r8a779h0 dt-bindings: display: bridge: renesas,dsi-csi2-tx: Add r8a779h0 drm/rcar-du: dsi: Add r8a779h0 support drm/rcar-du: Add support for r8a779h0 .../display/bridge/renesas,dsi-csi2-tx.yaml | 1 + .../devicetree/bindings/display/renesas,du.yaml | 67 ++++++++++++++++++++-- drivers/gpu/drm/renesas/rcar-du/rcar_du_drv.c | 18 ++++++ drivers/gpu/drm/renesas/rcar-du/rcar_du_group.c | 24 ++++++-- drivers/gpu/drm/renesas/rcar-du/rcar_mipi_dsi.c | 4 +- .../gpu/drm/renesas/rcar-du/rcar_mipi_dsi_regs.h | 1 - 6 files changed, 102 insertions(+), 13 deletions(-) --- base-commit: adc218676eef25575469234709c2d87185ca223a change-id: 20241008-rcar-gh-dsi-9c01f5deeac8 Best regards, -- Tomi Valkeinen <tomi.valkeinen(a)ideasonboard.com>

[PATCH v4 1/3] Drivers: hv: vmbus: Disable Suspend-to-Idle for VMBus

by Erni Sri Satya Vennela

This change is specific to Hyper-V VM user. If the Virtual Machine Connection window is focused, a Hyper-V VM user can unintentionally touch the keyboard/mouse when the VM is hibernating or resuming, and consequently the hibernation or resume operation can be aborted unexpectedly. Fix the issue by no longer registering the keyboard/mouse as wakeup devices (see the other two patches for the changes to drivers/input/serio/hyperv-keyboard.c and drivers/hid/hid-hyperv.c). The keyboard/mouse were registered as wakeup devices because the VM needs to be woken up from the Suspend-to-Idle state after a user runs "echo freeze > /sys/power/state". It seems like the Suspend-to-Idle feature has no real users in practice, so let's no longer support that by returning -EOPNOTSUPP if a user tries to use that.
