2025-01-15ASoC: Intel: sof_sdw: Fix DMI match for Lenovo 83JX, 83MC and 83NMSimon Trimmer
Update the DMI match for a Lenovo laptop to a new DMI identifier. This laptop ships with a different DMI identifier to what was expected and now has three match entries. It also has the DMICs connected to the host rather than the cs42l43 codec.

2025-01-15ASoC: dapm: add support for preparing streamsMartin Blumenstingl
Codec driver can implement .hw_params and/or .prepare from struct snd_soc_dai_ops. For codec-to-codec links only the former (.hw_params) callback has been called. On platforms like Amlogic Meson8/8b/8m2 the SoC's sound card (sound/soc/meson/gx-card.c) uses a codec-to-codec link for the HDMI codec output because further digital routing is required after the backend. The new DRM HDMI (audio) codec framework (which internally uses sound/soc/codecs/hdmi-codec.c) relies on the .prepare callback of the hdmi-codec to be called. Implement calls to snd_soc_dai_prepare() so the .prepare callback is called. In this case the mandatory part is the call to prepare the sink (which is the hdmi-codec on those platforms). Also call snd_soc_dai_prepare() for the source to stay consistent with the rest of the code (even though it's not strictly necessary to make the DRM HDMI codec framework work on Amlogic Meson8/8b/8m2). For platforms or sound cards without a codec-to-codec link with additional parameters (which applies to most hardware) this changes nothing as the .prepare callback is already called via snd_pcm_do_prepare() (as well as dpcm_fe_dai_prepare() and dpcm_be_dai_prepare()) on those.

2025-01-15ASoC: simple-card-utils: fix priv->dai_props indexingLaurentiu Mihalcea
As of commit cb18cd26039f ("ASoC: soc-core: do rtd->id trick at snd_soc_add_pcm_runtime()") the ID stored in the PCM runtime data can no longer be safely used to index the priv->dai_props array. This is because the ID may be modified during snd_soc_add_pcm_runtime(), thus resulting in an ID that's no longer a valid array index. To fix this, use the position of the dai_link stored inside the PCM runtime data relative to the start of the dai_link array as index into the priv->dai_props array.

Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

2025-01-15genirq: Provide IRQCHIP_MOVE_DEFERREDThomas Gleixner
The logic of GENERIC_PENDING_IRQ is backwards for historical reasons. Most interrupt controllers allow to move the interrupt from arbitrary contexts. If GENERIC_PENDING_IRQ is enabled by an architecture to support a chip, which requires the affinity change to happen in interrupt context, all other chips have to be marked with IRQF_MOVE_PCNTXT. That's tedious and there is no real good reason for the extra flags in the irq descriptor and the irq data status fields. In fact the decision whether interrupts can be moved in arbitrary context or not is a property of the interrupt chip. To simplify adoption for RISC-V provide a new mechanism which is enabled via a config switch and allows to add a flag to irq_chip::flags to request that interrupt affinity changes are deferred. Setting the top level chip of an interrupt evaluates the flag and maps it into the existing logic. The config switch and the various PCNTXT flags are temporary until x86 is converted over to this scheme. This intermediate step also allows trivial backporting of the mechanism to plug the affinity change race of various RISC-V interrupt controllers.

2025-01-15kbuild: rust: add PROCMACROLDFLAGSHONG Yifan
These are flags to be passed when linking proc macros for the Rust toolchain. If unset, it defaults to $(KBUILD_HOSTLDFLAGS). This is needed because the list of flags to link hostprogs is not necessarily the same as the list of flags used to link libmacros.so. When we build proc macros, we need the latter, not the former (e.g. when using a Rust compiler binary linked to a different C library than host programs). To distinguish between the two, introduce this new variable to stand out from KBUILD_HOSTLDFLAGS used to link other host progs.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier. There is also no real benefit in printing errors on missing syscon argument, because this is done just too late: runtime check on static/build-time data. Dtschema and Devicetree bindings offer the static/build-time check for this already.

Some boards with Allwinner SoCs connect the PMIC's IRQ pin to the SoC's NMI pin instead of a normal GPIO. Since the power key is connected to the PMIC, and people expect to wake up a suspended system via this key, the NMI IRQ controller must stay alive when the system goes into suspend. Add the SKIP_WAKE flag to prevent the sunxi NMI controller from going to sleep, so that the power key can wake up those systems.

2025-01-15irqchip/gic-v3: Handle CPU_PM_ENTER_FAILED correctlyYogesh Lal
When a CPU attempts to enter low power mode, it disables the redistributor and Group 1 interrupts and reinitializes the system registers upon wakeup. If the transition into low power mode fails, then the CPU_PM framework invokes the PM notifier callback with CPU_PM_ENTER_FAILED to allow the drivers to undo the state changes. The GIC V3 driver ignores CPU_PM_ENTER_FAILED, which leaves the GIC in disabled state. Handle CPU_PM_ENTER_FAILED in the same way as CPU_PM_EXIT to restore normal operation.

2025-01-15ALSA: hda: Transfer firmware in two chunksCezary Rojewski
As per specification, SDxLVI shall be at least 1 i.e.: two chunks to perform a valid transfer. This is true for the PCM transfer code but not firmware-transfer one. Technical background: - the LVI > 0 rule shall be obeyed in PCM transfer - HW permits LVI == 0 when transfer is SW-controlled (SPIB) - FW download is not a PCM transfer and is SW-controlled (SPIB) The above is the fundament which AudioDSP firmware loading functions have been built upon and worked since 2016. The presented changes are to align the loading flows and avoid rising more questions in the future. Achieve the goal by splitting snd_hdac_stream_setup_periods() into substream-dependent and -independent part. Let snd_hdac_dsp_prepare() utilize the latter so that both DSP-loading and PCM flows utilize same BLDE setup loop which already takes care of cutting the buffer based on azx_dev->period_bytes.

2025-01-14net: fec: handle page_pool_dev_alloc_pages errorKevin Groeneveld
The fec_enet_update_cbd function calls page_pool_dev_alloc_pages but did not handle the case when it returned NULL. There was a WARN_ON(!new_page) but it would still proceed to use the NULL pointer and then crash. This case does seem somewhat rare but when the system is under memory pressure it can happen. One case where I can duplicate this with some frequency is when writing over a smbd share to a SATA HDD attached to an imx6q. Setting /proc/sys/vm/min_free_kbytes to higher values also seems to solve the problem for my test case. But it still seems wrong that the fec driver ignores the memory allocation error and can crash.

2025-01-14Merge branch 'net-stmmac-further-eee-cleanups-and-one-fix'Jakub Kicinski
Russell King says: ==================== net: stmmac: further EEE cleanups (and one fix!) This series continues the EEE cleanup of the stmmac driver, and includes one fix. As mentioned in the previous series, I wasn't entirely happy with the "stmmac_disable_sw_eee_mode" name, so the first patch renames this to "stmmac_stop_sw_lpi" instead, which I think better describes what this function is doing - stopping the transmit of the LPI state because we have a packet ot send. Patch 2 corrects the priv->eee_sw_timer_en flag when EEE has been disabled. Currently upon disable, priv->eee_enabled is set false, but through the weird logic that was present prior to the previous series, priv->eee_sw_timer_en was set true. This behaviour was kept as the previous series was cleanup, not fixes. This patch fixes this. Having fixed priv->eee_sw_timer_en to actually indicate whether software timed EEE mode is being used, it becomes no longer necessary to test priv->eee_enabled in addition. Patch 3 removes the redundant test. Patch 4 also uses priv->eee_sw_timer_en before manipulating the software EEE state in the suspend method rather than using priv->eee_enabled, which brings consistency. Patch 5 provides stmmac_try_to_start_sw_lpi() which complements stmmac_stop_sw_lpi(), and allows us to move duplicated code into one location. Patch 6 splits stmmac_enable_eee_mode() - one part of this function tests whether there are any queues that have unfinished work (in other words are busy). Separate out this code into a separate function. Patch 7 also splits out the mod_timer() for the software EEE timer intoi a seperate function (the reason will be in patch 9.) Patch 8 merges the remains of stmmac_enable_eee_mode() into stmmac_try_to_start_sw_lpi(). Patch 9 fixes the delay between transmit and entering LPI. Currently, when cleaning the transmit queues, if we discover that we have finished cleaning up all queues, we immediately instruct the hardware to enter LPI mode without waiting for the LPI timer. However, we should wait for the LPI timer to expire. Therefore, the transmit cleanup path needs to call stmmac_restart_sw_lpi_timer() instead of stmmac_try_to_start_sw_lpi(). ==================== Link: https://patch.msgid.link/Z4T84SbaC4D-fN5y@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
