Correctly handle stopping and restarting the encoder, keeping track of the stop and drain states. In addition it adds correct handling of corner cases, allowing v4l2-compliance to pass. Unfortunately, the code is getting to be quite complicated, so we need to work on better codec support in v4l2-mem2mem.c to simplify drivers. Signed-off-by:

After a resolution change is detected, q_data->sizeimage is updated to the new format, but buf_prepare is still draining buffers that need to use the old pre-resolution-change value. So store the sizeimage value in q_data->vb2_sizeimage in queue_setup and use that in buf_prepare. Signed-off-by:

The stateful encoder requires the presence of this control. Since a single buffer is sufficient for vicodec, we just set this control to 1. Signed-off-by:

Setting the encoder output format to e.g. 1920x1080 will set the crop rectangle to 1920x1088, the coded resolution to 1920x1088 and the capture coded resolution and sizeimage to 1920x1088 as well. Note that this might change, since the encoder spec is still in flux with respect to how this should behave. Signed-off-by:

Amlogic SoCs feature a powerful video decoder unit able to decode many formats, with a performance of usually up to 4k60. This is a driver for this IP that is based around the v4l2 m2m framework. It features decoding for: - MPEG 1 - MPEG 2 Supported SoCs are: GXBB (S905), GXL (S905X/W/D), GXM (S912) There is also a hardware bitstream parser (ESPARSER) that is handled here. Signed-off-by:

The IR protocol can now only be set via the rc protocols sysfs file rather than via module parameters or a custom procfs file. So, it is no longer necessary to periodically check for protocol changes. The IR_RCMM protocol does not decode the Philips RC-MM protocol (12, 24 or 32 bit variants) or any protocol rc-core can encode, so this is marked RC_PROTO_UNKNOWN. Tested on Technotrend/Hauppauge WinTV Nexus-S rev2.1, which comes with a small black hauppauge remote. Signed-off-by:

Commit 020bc735 ("media: staging/imx: Allow driver to build if COMPILE_TEST is enabled") incorrectly assumed that the imx media driver had no build time dependency with IMX_IPUV3_CORE. Building on x86_64 without IMX_IPUV3_CORE causes lots of build errors such as: All these definitions come from the imx ipu3 core driver, so make sure that imx media depends on IMX_IPUV3_CORE. This reverts commit 020bc735. Reported-by:

There are cases that interrupt bits are cleared by a 500ms delayed work which causes unnecessary irq calls. Also, the current interrupt handler returns IRQ_HANDLED always but it should return IRQ_NONE if there is any unhandled interrupt. So this commit refines the interrupt handling logic to fix these issues. Signed-off-by:

VE_INTERRUPT_CAPTURE_COMPLETE and VE_INTERRUPT_COMP_COMPLETE are not set at the same time but the current interrupt handling mechanism of this driver doesn't clear the interrupt flag until both two are set, and this behavior causes unnecessary interrupt handler calls. In fact, this driver provides JPEG format only so taking care of the VE_INTERRUPT_COMP_COMPLETE is enough for getting compressed image frame so this commit gets rid of the VE_INTERRUPT_CAPTURE_COMPLETE checking logic to simplify the logic. Handling of VE_INTERRUPT_CAPTURE_COMPLETE could be added back later when it's actually needed. Signed-off-by:

Currently, this driver prints out too much log messages when a mode change happens, video turned off by screen saver and etc. Actually, all cases are reported to user space properly. Also, these are not critical errors but recoverable things, so this commit changes the log level of some noisy printing outs. Signed-off-by:

Video Engine has a dedicated interrupt line so this driver doesn't need to use IRQF_SHARED flag so remove it. Also, it'd be good for following what Thomas recommended in the IRQF_ONESHOT support patch like below: "Note that for now IRQF_ONESHOT cannot be used with IRQF_SHARED to avoid complex accounting mechanisms."

Differently from other Aspeed drivers, this driver calls clock control APIs in interrupt context. Since ECLK is coupled with a reset bit in clk-aspeed module, aspeed_clk_enable will make 10ms of busy waiting delay for triggering the reset and it will eventually disturb other drivers' interrupt handling. To fix this issue, this commit changes this driver's irq to threaded irq so that the delay can be happened in a thread context. Signed-off-by:

Currently, this driver calls clk_prepare and clk_unprepare from interrupt context too but these should be called from sleepable context only. To fix this issue, this commit splits out clk_enable/disable and clk_prepare/unprepare, and it places clk_prepare/unprepare calls into the module probe/remove function. Signed-off-by:
