2024-07-09soundwire: intel_auxdevice: start the bus at default frequencyPierre-Louis Bossart
When platform firmware exposes multiple supported bus frequencies, the existing SoundWire support selects the maximum frequency. This is not aligned with the SoundWire 1.2 directions: the MIPI recommendation is to start at a 'safe' speed, compatible with the default frame rate and shape, and only increase the clock when vendor and codec PHY parameters are updated. However, clock changes are not supported for now by the SoundWire core, so in practice this patch has the effect of discarding frequencies different to the implicit default. Dynamic clock changes will be required at some point, and this limitation will be removed after the core is updated, specifically to perform synchronous clock scale changes on manager and peripheral sides with a bank switch. On Intel LunarLake platforms with a 'standard' DSDT, this forces the use of 4.8MHz. On older platforms this patch has no effect.

GPIOs controlling backlight on Spitz and Akita are coming from GPIO expanders, not the pxa27xx-gpio block, correct it. Additionally GPIO lookup tables operate with pin numbers rather than legacy GPIO numbers, fix that as well. Use raw numbers instead of legacy GPIO names to avoid confusion.

2024-07-09vdpa/mlx5: Don't reset VQs more than necessaryDragos Tatulea
The vdpa device can be reset many times in sequence without any significant state changes in between. Previously this was not a problem: VQs were torn down only on first reset. But after VQ pre-creation was introduced, each reset will delete and re-create the hardware VQs and their associated resources. To solve this problem, avoid resetting hardware VQs if the VQs are still in a blank state.

2024-07-09vdpa/mlx5: Re-create HW VQs under certain conditionsDragos Tatulea
There are a few conditions under which the hardware VQs need a full teardown and setup: - VQ size changed to something else than default value. Hardware VQ size modification is not supported. - User turns off certain device features: mergeable buffers, checksum virtio 1.0 compliance. In these cases, the TIR and RQT need to be re-created. Add a needs_teardown configuration variable and set it when detecting the above scenarios. On next DRIVER_OK, the resources will be torn down first.

2024-07-09vdpa/mlx5: Pre-create hardware VQs at vdpa .dev_add timeDragos Tatulea
Currently, hardware VQs are created right when the vdpa device gets into DRIVER_OK state. That is easier because most of the VQ state is known by then. This patch switches to creating all VQs and their associated resources at device creation time. The motivation is to reduce the vdpa device live migration downtime by moving the expensive operation of creating all the hardware VQs and their associated resources out of downtime on the destination VM. The VQs are now created in a blank state. The VQ configuration will happen later, on DRIVER_OK. Then the configuration will be applied when the VQs are moved to the Ready state. When .set_vq_ready() is called on a VQ before DRIVER_OK, special care is needed: now that the VQ is already created a resume_vq() will be triggered too early when no mr has been configured yet. Skip calling resume_vq() in this case, let it be handled during DRIVER_OK. For virtio-vdpa, the device configuration is done earlier during .vdpa_dev_add() by vdpa_register_device(). Avoid calling setup_vq_resources() a second time in that case. On a 64 CPU, 256 GB VM with 1 vDPA device of 16 VQps, the full VQ resource creation + resume time was ~370ms. Now it's down to 60 ms (only VQ config and resume). The measurements were done on a ConnectX6DX based vDPA device.
