Subject: [PATCH] ClientNativePixmapFactoryDmabuf uses ioctl, instead of
|
|
drmIoctl.
|
|
|
|
DMA_BUF_SYNC ioctl is not drmIoctl, because it uses dma-buf fd, instead of drm
|
|
device fd.
|
|
|
|
In addition, remove LOCAL_ prefix to fix build failure >= kernel 4.6
|
|
|
|
Actually, ChromeOS doesn't need this local DMA_BUF_SYNC definition as all
|
|
verion of kernel for cros has dma-buf.h header.
|
|
https://chromium-review.googlesource.com/c/459544/
|
|
However, there is not any way to distinguish real ChromeOS build and
|
|
current_os="chromeos" build, so remain the local definition to ChromeOS as
|
|
well.
