Changes since v3: - Rebase on v5.9-rc1. - modify code for review comment from Rob Herring, cancel multiple nodes using same register base situation. - control IOMMU port through pm runtime get/put to DMA components' device. - SCP(VPU) driver revision. - stop queuing jobs(remove flush_workqueue()) after mdp_m2m_release(). - add computation of plane address with data_offset. - fix scale ratio check issue. - add default v4l2_format setting. Changes since v2: - modify code for review comment from Tomasz Figa & Alexandre Courbot - review comment from Rob Herring will offer code revision in v4, due to it's related to device node modification, will need to modify code architecture Changes since v1: - modify code for CMDQ v3 API support - EC ipi cmd migration - fix compliance test fail item (m2m cmd with -f) due to there is two problem in runing all format(-f) cmd: 1. out of memory before test complete Due to capture buffer mmap (refcount + 1) after reqbuf but seems no corresponding munmap called before device close. There are total 12XX items(formats) in format test and each format alloc 8 capture/output buffers. 2. unceasingly captureBufs() (randomly) Seems the break statement didn't catch the count == 0 situation: In v4l2-test-buffers.cpp, function: captureBufs() ... count--; if (!node->is_m2m && !count) break; Log is as attachment I will paste the test result with problem part in another e-mail Hi, This is the first version of RFC patch for Media Data Path 3 (MDP3), MDP3 is used for scaling and color format conversion. support using GCE to write register in critical time limitation. support V4L2 m2m device control.
