Thomas Zimmermann authored
Udl has a single display pipeline with a primary plane; perfect for simple-pipe helpers. Convert it over. The old encoder and CRTC code becomes unused and obsolete. Exported formats for the primary plane are RGB565 and XRGB8888, with the latter being emulated. The 16-bit format is the default and what is used when communicating with the device. This patch enables atomic modesetting for udl devices. v3: * remove unused field crtc from struct udl_device * set crtc_state->no_vblank at beginning of enable() v2: * move suspend/resume changes into separate patch * remove non-atomic code Signed-off-by:

This framework allows a unified userspace interface for dma-buf exporters, allowing userland to allocate specific types of memory for use in dma-buf sharing. Each heap is given its own device node, which a user can allocate a dma-buf fd from using the DMA_HEAP_IOC_ALLOC.

Reading the primary plane's framebuffer from the CRTC's atomic_flush() function is fragile as the plane state or framebuffer can be NULL. Instead, we let the plane's atomic_check() store the framebuffer format in the CRTC state. The CRTC always receives the framebuffer format that is currently programmed, or NULL if no mode has been set yet. Signed-off-by:

The Amlogic G12A AFBC Decoder pixel input need to be routed diferently than the Amlogic GXM AFBC decoder, this adds support for routing the VIU OSD1 pixel source to the AFBC "Mali Unpack" module.

This adds all the OSD configuration plumbing to support the AFBC decoders path to display of the OSD1 plane. The Amlogic GXM and G12A AFBC decoders are integrated very differently. The Amlogic GXM has a direct output path to the OSD1 VIU pixel input, because the GXM AFBC decoder seem to be a custom IP developed by Amlogic. On the other side, the Amlogic G12A AFBC decoder seems to be an external IP that emit pixels on an AXI master hooked to a "Mali Unpack" block feeding the OSD1 VIU pixel input. This uses a weird "0x1000000" internal HW physical address on both sides to transfer the pixels. For Amlogic GXM, the supported pixel formats are the same as the normal linear OSD1 mode. On the other side, Amlogic added support for all AFBC v1.2 formats for the G12A AFBC integration. For simplicity, we stick to the already supported formats for now. Signed-off-by:

This adds the driver for the ARM Framebuffer Compression decoders found in the Amlogic GXM and G12A SoCs. The Amlogic GXM and G12A AFBC decoder are totally different, the GXM only handling only the AFBC v1.0 modes and the G12A decoder handling the AFBC v1.2 modes. The G12A AFBC decoder is an external IP integrated in the video pipeline, and the GXM AFBC decoder seems to the an Amlogic custom decoder more tighly integrated in the video pipeline. The GXM AFBC decoder can handle only one AFBC plane for 2 available OSD planes available in HW, and the G12A AFBC decoder can handle up to 4 AFBC planes for up to 3 OSD planes available in HW. The Amlogic GXM supports 16x16 SPARSE and 16x16 SPLIT AFBC buffers up to 4k. On the other side, for G12A SPLIT is mandatory in 16x16 block mode, but for 4k modes 32x8+SPLIT AFBC buffers is manadatory for performances reasons. The RDMA is used here to reset and program the AFBC decoder unit on each vsync without involving the interrupt handler that can be masked for a long period of time, producing display glitches. For this we use the meson_rdma_writel_sync() which adds the register write tuple (VPU register offset and register value) to the RDMA buffer and write the value to the HW. When enabled, the RDMA is enabled to rewrite the same sequence at the next VSYNC event, until a new buffer is committed to the OSD plane. Then the Amlogic G12A is switched to RDMA, the Amlogic GXM Decoder doesn't need a reset/reprogram at each vsync, but needs to keep the vsync interrupt enabled to trigger the RDMA module.

The VPU embeds a "Register DMA" that can write a sequence of registers on the VPU AHB bus, either manually or triggered by an internal IRQ event like VSYNC or a line input counter. The initial implementation handles a single channel (over 8), triggered by the VSYNC irq and does not handle the RDMA irq. The RDMA will be usefull to reset and program the AFBC decoder unit on each vsync without involving the interrupt handler that can be masked for a log period of time, producing display glitches.
