project:cfg:BoardConfig_IPC: Added fastboot BoardConfig file and firmware post-scripts, distinguishing between the BoardConfigs for Luckfox Pico Pro and Luckfox Pico Max. project:app: Added fastboot_client and rk_smart_door for quick boot applications; updated rkipc app to adapt to the latest media library. media:samples: Added more usage examples. media:rockit: Fixed bugs; removed support for retrieving data frames from VPSS. media:isp: Updated rkaiq library and related tools to support connection to RKISP_Tuner. sysdrv:Makefile: Added support for compiling drv_ko on Luckfox Pico Ultra W using Ubuntu; added support for custom root filesystem. sysdrv:tools:board: Updated Buildroot optional mirror sources, updated some software versions, and stored device tree files and configuration files that undergo multiple modifications for U-Boot and kernel separately. sysdrv:source:mcu: Used RISC-V MCU SDK with RT-Thread system, mainly for initializing camera AE during quick boot. sysdrv:source:uboot: Added support for fastboot; added high baud rate DDR bin for serial firmware upgrades. sysdrv:source:kernel: Upgraded to version 5.10.160; increased NPU frequency for RV1106G3; added support for fastboot.

maintenance to a range within the dma-buf.

|

The Sync File Framework adds explicit synchronization via
|
|
userspace. It enables send/receive 'struct dma_fence' objects to/from
|
|
userspace via Sync File fds for synchronization between drivers via
|
|
userspace components. It has been ported from Android.
|
|
|
|
The first and main user for this is graphics in which a fence is
|
|
associated with a buffer. When a job is submitted to the GPU a fence
|
|
is attached to the buffer and is transferred via userspace, using Sync
|
|
Files fds, to the DRM driver for example. More details at
|
|
Documentation/driver-api/sync_file.rst.

Don't pin buffers if the dynamic DMA-buf interface is available on

both the exporter as well as the importer. This fixes a security
|
|
problem where userspace is able to pin unrestricted amounts of memory
|
|
through DMA-buf.

This is marked experimental because we don't yet have a consistent
|
|
execution context and memory management between drivers.
