media: iris: Guard the QCOM_UBWC_CONFIG select with QCOM_SMEM

2026-08-18T09:17:48Z

QCOM_UBWC_CONFIG is about to depend on QCOM_SMEM. Guard the VIDEO_QCOM_IRIS select with 'if ARCH_QCOM && QCOM_SMEM', and add 'depends on QCOM_SMEM || QCOM_SMEM=n' so a built-in driver is never selected against a missing or modular SMEM.

media: iris: disable time-delta-based rate control for VBR

2026-07-30T10:02:21Z

The iris encoder driver was not sending HFI_PROP_TIME_DELTA_BASED_RATE_CONTROL to the firmware during encoder initialization. Without this property, the firmware defaults to time-delta-based rate control (enabled), which calculates the output bitrate from actual frame timing rather than following the configured bitrate target. This caused variable bitrate (VBR) encoding to produce ~5x configured bitrate. For example, with video_bitrate=896000 (896 Kbps), the output is ~4.4 Mbps instead of the expected ~896 Kbps. Time-delta-based rate control is designed for variable frame rate (VFR) scenarios where the encoder adapts to actual frame timing. However, when an application explicitly configures a bitrate target, the firmware must follow that target regardless of frame timing. Fix this by adding the TIME_DELTA_BASED_RC capability with a default value of 0 (disabled) and sending HFI_PROP_TIME_DELTA_BASED_RATE_CONTROL = 0 to the firmware during stream-on, allowing the firmware to use the configured bitrate as the target.

media: iris: Add Gen2 firmware autodetect and fallback

2026-07-30T09:47:48Z

Some Iris platforms support both Gen1 and Gen2 HFI firmware images. Update the firmware loading logic to handle this generically by preferring Gen2 when available, while safely falling back to Gen1 when required. The firmware loading logic is updated with the following priority: 1. Device Tree (`firmware-name`): If specified, load unconditionally. 2. Gen2 default : If no DT override exists, select the Gen2 firmware descriptor when present and attempt to load the corresponding firmware image. 3. Gen1 Fallback: If loading the Gen2 firmware fails and a Gen1 descriptor is available, retry with the Gen1 firmware image. When a platform provides both Gen1 and Gen2 firmware descriptors and the firmware is loaded via a DT override, the driver detects the firmware generation at runtime before authentication by inspecting the firmware data. The firmware is classified as Gen2 if the QC_IMAGE_VERSION_STRING starts with "vfw" or matches the "video-firmware.N.M" format with N >= 2. If a Gen1 firmware image is detected in this case, the driver switches to the Gen1 firmware descriptor and associated platform data so that the correct HFI implementation is used. This change makes firmware generation detection platform‑agnostic, preserves DT overrides, prefers newer Gen2 firmware when available, and maintains compatibility with platforms that only support Gen1.

media: qcom: iris: use disable_irq() during power-off

2026-07-30T09:47:47Z

The IRQ is registered as a threaded IRQ. Using disable_irq_nosync() in iris_vpu_power_off() does not wait for an already queued threaded IRQ handler to complete before returning. As a result, a threaded IRQ handler may still run after the VPU has been powered down and access hardware registers after power-off. Replace disable_irq_nosync() with disable_irq() so the power-off path waits for any in-flight threaded IRQ handler to complete before returning.

Check the return value of pm_runtime_resume_and_get() in iris_core_deinit(). If runtime PM resume fails, skip hardware power-off operations but still perform software teardown and state transition. Also skip the corresponding pm_runtime_put_sync() call to avoid unbalanced runtime PM references.
