drm/ttm: add io_mem_pfn callback

2017-04-05T03:33:42Z

This allows the driver to handle io_mem mappings on their own. Signed-off-by: Christian König Reviewed-by: Michel Dänzer Reviewed-by: Nicolai Hähnle Signed-off-by: Alex Deucher

drm/ttm: add ttm_bo_init_reserved

2017-03-30T03:53:07Z

This variant of ttm_bo_init returns the validated buffer object with the reservation lock held when resv == NULL. This is convenient for callers that want to use the BO immediately, e.g. for initializing its contents. Signed-off-by: Nicolai Hähnle Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/ttm: fix the documentation of ttm_bo_init

2017-03-30T03:53:06Z

As the comment says: callers of ttm_bo_init cannot rely on having the only reference to the BO when the function returns successfully. Signed-off-by: Nicolai Hähnle Reviewed-by: Christian König Signed-off-by: Alex Deucher

Pull drm updates from Dave Airlie: "This is the main drm pull request for v4.11. Nothing too major, the tinydrm and mmu-less support should make writing smaller drivers easier for some of the simpler platforms, and there are a bunch of documentation updates. Intel grew displayport MST audio support which is hopefully useful to people, and FBC is on by default for GEN9+ (so people know where to look for regressions). AMDGPU has a lot of fixes that would like new firmware files installed for some GPUs. Other than that it's pretty scattered all over. I may have a follow up pull request as I know BenH has a bunch of AST rework and fixes and I'd like to get those in once they've been tested by AST, and I've got at least one pull request I'm just trying to get the author to fix up.

drm/ttm: add BO priorities for the LRUs

2017-01-27T17:20:33Z

This way the driver can specify a priority for a BO which has the effect that a BO is only evicted when all other BOs with a lower priority are evicted first. Reviewed-by: Sinclair Yeh Signed-off-by: Christian König Reviewed-by: Roger.He Signed-off-by: Alex Deucher

dma-buf: Rename struct fence to dma_fence

2016-10-25T12:40:39Z

I plan to usurp the short name of struct fence for a core kernel struct, and so I need to rename the specialised fence/timeline for DMA operations to make room. A consensus was reached in https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html that making clear this fence applies to DMA operations was a good thing. Since then the patch has grown a bit as usage increases, so hopefully it remains a good thing!
