我需要在当前运行内核版本 4.14 的设备中使用 wlan 驱动程序 (ATH10K_SDIO)，其中只有该驱动程序的实验性非功能版本可用。升级内核并不是一个真正的选择。
我尝试从以下位置向后移植驱动程序Linux 内核 v4.19到Linux 内核 v4.14。我用的是向后移植 repo 分支 linux-4.19.y将驱动程序向后移植并集成到旧的内核源代码树中。由于补丁失败0090-删除-GRO_CONSUMED.patch。
即使我从补丁列表中删除了这个补丁，向后移植仍然失败（它无法修补集成补丁进入源代码树）。
所有这些让我想知道，这就是您使用驱动程序反向移植工具的方式吗？如果是这样，我错过了什么？
谢谢
约翰内斯
编辑：我需要驱动程序的设备正在使用https://github.com/Xilinx/linux-xlnx（版本 2018.2）在 Linux 4.14 之上有数百处更改，因此使用 Linux Stable 并不是真正的选择。但准确使用4.14.0时也会出现上述错误。

答案1
ATH10K_SDIO 支持位于最新的 4.14 更新中，因此只需更新到更新的 4.14 内核版本即可获得驱动程序。我建议更新整个内核并移植您拥有的发行版特定补丁。
参考：kernel.org https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/net/wireless/ath/ath10k?h=linux-4.14.y
您应该能够使用 GitHub fork 将当前的内核变更集（无论是您的还是其他人的）转发到此。
