2019-08-13dma-buf: rename reservation_object to dma_resvChristian König1-3/+3
Be more consistent with the naming of the other DMA-buf objects. Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/323401/

2019-08-05dma-buf: add more reservation object locking wrappersChristian König1-2/+2
Complete the abstraction of the ww_mutex inside the reservation object. This allows us to add more handling and debugging to the reservation object in the future.

2019-07-31drm/radeon: Fill out gem_object->resvDaniel Vetter1-7/+0
That way we can ditch our gem_prime_res_obj implementation. Since ttm absolutely needs the right reservation object all the boilerplate is already there and we just have to wire it up correctly. Note that gem/prime doesn't care when we do this, as long as we do it before the bo is registered and someone can call the handle2fd ioctl on it. Aside: ttm_buffer_object.ttm_resv could probably be ditched in favour of always passing a non-NULL resv to ttm_bo_init(). At least for gem drivers that would avoid having two of these, on in ttm_buffer_object and the other in drm_gem_object, one just there for confusion.

2014-08-11drm/radeon: add userptr support v8Christian König1-0/+10
This patch adds an IOCTL for turning a pointer supplied by userspace into a buffer object. It imposes several restrictions upon the memory being mapped: 1. It must be page aligned (both start/end addresses, i.e ptr and size). 2. It must be normal system memory, not a pointer into another map of IO space (e.g. it must not be a GTT mmapping of another object). 3. The BO is mapped into GTT, so the maximum amount of memory mapped at all times is still the GTT limit. 4. The BO is only mapped readonly for now, so no write support. 5. List of backing pages is only acquired once, so they represent a snapshot of the first use. Exporting and sharing as well as mapping of buffer objects created by this function is forbidden and results in an -EPERM. v2: squash all previous changes into first public version v3: fix tabs, map readonly, don't use MM callback any more v4: set TTM_PAGE_FLAG_SG so that TTM never messes with the pages, pin/unpin pages on bind/unbind instead of populate/unpopulate v5: rebased on 3.17-wip, IOCTL renamed to userptr, reject any unknown flags, better handle READONLY flag, improve permission check v6: fix ptr cast warning, use set_page_dirty/mark_page_accessed on unpin v7: add warning about it's availability in the API definition v8: drop access_ok check, fix VM mapping bits Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> (v4) Reviewed-by: Jérôme Glisse <jglisse@redhat.com> (v4) Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-01-08drm/prime: drop reference on imported dma-buf come from gemSeung-Woo Kim1-0/+1
Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem makes memory leak. release function of dma-buf cannot be called because f_count of dma-buf increased by importing gem and gem ref count cannot be decrease because of exported dma-buf. So I add dma_buf_put() for imported gem come from its own gem into each drivers having prime_import and prime_export capabilities. With this, only gem ref count is increased if importing gem exported from gem of same driver.

Remove redundant DRM UAPI header #inclusions from drivers/gpu/. Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding patch. Without this patch and the patch to make include the UAPI headers from the core headers, after the UAPI split, the DRM C sources cannot find these UAPI headers because the DRM code relies on specific -I flags to make #include "..." work on headers in include/drm/ - but that does not work after the UAPI split without adding more -I flags.
