From def59d5aa61099be03a81e5189014ffe23f222e5 Mon Sep 17 00:00:00 2001 From: Fumiya Kohzu Date: Thu, 30 Nov 2023 13:28:56 +0900 Subject: UnifiedHMI: Update SRCREV for RVGPU and virtio-loopback-driver, and upgrade mesa-virtio. - OSS RVGPU update: Support for xdg_shell. - OSS virtio-gpu-driver update: Simplify directory structure, not use cmake. - Recipe updates: 1, Update SRCREV for RVGPU. Since RVGPU now supports xdg_shell in OSS, the patch enabling xdg_shell has been removed. 2, Remove the agl-shell-desktop interface because it is planned to be phased out. 3, Upgrade the base mesa for mesa-virtio from 18.2.0 to 20.3.5. Remove patches that were used with mesa-18.2.0. We are exploring ways to run it with the newer mesa. 4, Update SRCREV for virtio-loopback-driver. 5, Update meta-data for patches of RVGPU and virtio-gpu-driver. The content of the patches remains unchanged. We are planning to support a gRPC protocol interface for RVGPU.

Instead, data is serialized into -virgl internal command and sent using VIRTIO_GPU_CMD_SUBMIT_3D -comand. This command is opaque for rproxy/rvdds and serialized cmd buffer -is just forwarded to virglrenderer, where it is deserialized and -used for initialization of internal "gpu" memory with this data. -2) glMapBuffer --- this calls TRANSFER_FROM_HOST_3D, which asks host/rproxy--> -rvdds/virglrenderer to update backing memory (on source) with buffer data. -And further this backing memory is mapped to guest application. -In case of UHMI, TRANSFER_FROM_HOST_3D is not implemented, thus the memory is -not "initialized". -3) Modify buffer memory, but not whole memory, just some chunks. -4) glUnmapBuffer --- this will trigger VIRTIO_GPU_CMD_TRANSFER_TO_HOST_3D -command, which will send to target whole buffer memory and will overwrite -previous memory.
