Lynne	53c56585a6	hwcontext_drm: make dependency on Linux kernel headers optional ... This was introduced in version 4.6. And may not exist all without an optional package. So to prevent a hard dependency on needing the Linux kernel headers to compile, make this optional. Also ignore the status of the ioctl, since it may fail on older kernels which don't support it. It's okay to ignore as its not fatal and any serious errors will be caught later by the mmap call.	2020-12-30 23:14:46 +01:00
Lynne	993d8d9429	hwcontext_drm: issue DMA_BUF_IOCTL_SYNC when mapping FDs ... This improves performance and helps a little when given FDs without any synchronization fences.	2020-11-25 23:06:34 +01:00
