2023-02-13selftests: dmabuf-heaps: Fix incorrect kernel headers search pathMathieu Desnoyers2-3/+2
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=...).

2021-02-08kselftests: dmabuf-heaps: Add extra checking that allocated buffers are zeroedJohn Stultz1-0/+86
Add a check to validate that buffers allocated from the heaps are properly zeroed before being given to userland. It is done by allocating a number of buffers, and filling them with a nonzero pattern, then closing and reallocating more buffers and checking that they are all properly zeroed. This is helpful to validate any cached buffers are zeroed before being given back out.

2021-02-08kselftests: dmabuf-heaps: Softly fail if don't find a vgem deviceJohn Stultz1-8/+7
While testing against a vgem device is helpful for testing importing they aren't always configured in, so don't make it a fatal failure.

2021-02-08kselftests: dmabuf-heaps: Fix Makefile's inclusion of the kernel's ↵John Stultz1-1/+1
usr/include dir 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 Cc: Shuah Khan <[email protected]> Cc: Brian Starkey <[email protected]> Cc: Sumit Semwal <[email protected]> Cc: Laura Abbott <[email protected]> Cc: Hridya Valsaraju <[email protected]> Cc: Suren Baghdasaryan <[email protected]> Cc: Sandeep Patil <[email protected]> Cc: Daniel Mentz <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Fixes: a8779927fd86c ("kselftests: Add dma-heap test") Signed-off-by: John Stultz <[email protected]> Signed-off-by: Shuah Khan <[email protected]>
2020-05-08kselftests: dmabuf-heaps: Fix confused return value on expected error testingJohn Stultz1-0/+1
When I added the expected error testing, I forgot I need to set the return to zero when we successfully see an error. Without this change we only end up testing a single heap before the test quits.

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.
