selftests: dmabuf-heaps: Fix incorrect kernel headers search path

2023-02-13T16:09:44+00:00

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).

kselftests: dmabuf-heaps: Fix Makefile's inclusion of the kernel's usr/include dir

2021-02-08T23:25:15+00:00

Copied in from somewhere else, the makefile was including
the kerne's usr/include dir, which caused the asm/ioctl.h file
to be used.

Unfortunately, that file has different values for _IOC_SIZEBITS
and _IOC_WRITE than include/uapi/asm-generic/ioctl.h which then
causes the _IOCW macros to give the wrong ioctl numbers,
specifically for DMA_BUF_IOCTL_SYNC.

This patch simply removes the extra include from the Makefile

kselftests: Add dma-heap test

Add very trivial allocation and import test for dma-heaps,
utilizing the vgem driver as a test importer.

This reverts commit ab87cc9754cdeb373c8ac030ac7aed92f450b767.

This patchset doesn't meet the UAPI requirements set out in [1] for the DRM
subsystem. Once the userspace component is reviewed and ready for merge
we can try again.
