2024-02-01media: rkisp1: Fix IRQ handling due to shared interruptsTomi Valkeinen1-0/+3
The driver requests the interrupts as IRQF_SHARED, so the interrupt handlers can be called at any time. If such a call happens while the ISP is powered down, the SoC will hang as the driver tries to access the ISP registers. This can be reproduced even without the platform sharing the IRQ line: Enable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will hang. Fix this by adding a new field, 'irqs_enabled', which is used to bail out from the interrupt handler when the ISP is not operational.

2023-12-09media: rkisp1: Fix IRQ disable race issueTomi Valkeinen1-3/+17
In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the interrupts and then apparently assumes that the interrupt handler won't be running, and proceeds in the stop procedure. This is not the case, as the interrupt handler can already be running, which would lead to the ISP being disabled while the interrupt handler handling a captured frame. This brings up two issues: 1) the ISP could be powered off while the interrupt handler is still running and accessing registers, leading to board lockup, and 2) the interrupt handler code and the code that disables the streaming might do things that conflict. It is not clear to me if 2) causes a real issue, but 1) can be seen with a suitable delay (or printk in my case) in the interrupt handler, leading to board lockup.

2023-12-04media: v4l2-subdev: Rename .init_cfg() operation to .init_state()Laurent Pinchart1-3/+7
The subdev .init_cfg() operation is affected by two issues: - It has long been extended to initialize a whole v4l2_subdev_state instead of just a v4l2_subdev_pad_config, but its name has stuck around. - Despite operating on a whole subdev state and not being directly exposed to the subdev users (either in-kernel or through the userspace API), .init_cfg() is categorized as a subdev pad operation. This participates in making the subdev API confusing for new developers. Fix it by renaming the operation to .init_state(), and make it a subdev internal operation.

Use the V4L2 subdev active state API to store the active format and crop rectangle. This simplifies the driver not only by dropping the state stored in the rkisp1_isp structure, but also by replacing the ops_lock with the state lock. The rkisp1_isp.sink_fmt field needs to be kept, as it is accessed from the stats interrupt handler. To simplify the rkisp1_isp_set_sink_fmt() implementation, the field is now set when starting the ISP, instead of when setting the format.

2022-09-24media: rkisp1: Configure LSC after enabling the ISPLaurent Pinchart1-3/+6
The ISP8000Nano v18.02 (found in the i.MX8MP) requires the ISP to be enabled (as indicated by the ISP_CTRL.ISP_ENABLE bit) to configure the lens shading table in internal RAM. The driver currently configures all ISP initial parameters before enabling the ISP, which causes the LSC RAM to not be initialized properly. To fix this, split the rkisp1_params_configure() function into a rkisp1_params_pre_configure() and a rkisp1_params_post_configure(). The former configures all ISP parameters but LSC, while the latter configures LSC. To implement this, the rkisp1_params_apply_params_cfg() function is deconstructed, with two small helpers created to deal with the parameters buffers, which are then used in rkisp1_params_isr(), rkisp1_params_pre_configure() and rkisp1_params_post_configure(). While this initialization ordering is only needed for the ISP8000Nano v18.02, it doesn't affect other ISP versions negatively, and can thus be followed unconditionally.

The driver currently only implements the Rec. 601 YCbCr encoding, extend it with support for the other encodings defined by V4L2 (Rec. 709, Rec. 2020 and SMPTE240m). The coefficients have been calculated by rounding the floating point values to the nearest Q1.7 fixed-point value, adjusting the rounding to ensure that the sum of each line in the matrix is preserved to avoid overflows. At the hardware level, the RGB to YUV conversion matrix is fully configurable, custom encoding could be supported by extending the ISP parameters if desired.

The ISP output color space is configured through the ISP source pad. At the moment, only the quantization can be set. Extend it to the three other color space fields: - The ycbcr_enc field will be used to configure the RGB to YUV matrix (currently hardcoded to Rec. 601). - The colorspace (which controls the color primaries) and xfer_func fields will not be used to configure the ISP, as the corresponding hardware blocks (the cross-talk RGB to RGB matrix and the tone mapping curve) are programmed directly by applications through ISP parameters. Nonetheless, those two fields should be set by applications to match the ISP configuration, in order to propagate the correct color space down the pipeline up to the capture video nodes.

The ISP converts Bayer data to YUV when operating normally, and can also operate in pass-through mode where the input and output formats must match. Converting from YUV to Bayer isn't possible.

The ISP accepts different color spaces on its input: for YUV input, it doesn't set any restrictions, and for Bayer inputs, any color primaries or transfer function can be accepted (YCbCr encoding isn't applicable there, and quantization range can only be full). Allow setting a color space on the ISP sink pad, with the aforementioned restrictions. The settings don't influence hardware yet (only the YUV quantization range will, anything else has no direct effect on the ISP configuration), but can already be set to allow color space information to be coherent across the ISP sink link.
