drm/msm: Remove 'src_clk' from adreno configuration

2016-11-28T20:14:13Z

The adreno code inherited a silly workaround from downstream from the bad old days before decent clock control. grp_clk[0] (named 'src_clk') doesn't actually exist - it was used as a proxy for whatever the core clock actually was (usually 'core_clk'). All targets should be able to correctly request 'core_clk' and get the right thing back so zap the anachronism and directly use grp_clk[0] to control the clock rate.

drm/msm: convert iova to 64b

2016-11-28T20:14:08Z

For a5xx the gpu is 64b so we need to change iova to 64b everywhere. On the display side, iova is still 32b so it can ignore the upper bits. (Although all the armv8 devices have an iommu that can map 64b pa to 32b iova.) Signed-off-by: Rob Clark

drm/msm: support multiple address spaces

2016-11-27T16:23:09Z

We can have various combinations of 64b and 32b address space, ie. 64b CPU but 32b display and gpu, or 64b CPU and GPU but 32b display. So best to decouple the device iova's from mmap offset. Signed-off-by: Rob Clark

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! (v2...: rebase, rerun spatch) v3: Compile on msm, spotted a manual fixup that I broke. v4: Try again for msm, sorry Daniel coccinelle script: @@ @@ - struct fence + struct dma_fence @@ @@ - struct fence_ops + struct dma_fence_ops @@ @@ - struct fence_cb + struct dma_fence_cb @@ @@ - struct fence_array + struct dma_fence_array @@ @@ - enum fence_flag_bits + enum dma_fence_flag_bits @@ @@ ( - fence_init + dma_fence_init | - fence_release + dma_fence_release | - fence_free + dma_fence_free | - fence_get + dma_fence_get | - fence_get_rcu + dma_fence_get_rcu | - fence_put + dma_fence_put | - fence_signal + dma_fence_signal | - fence_signal_locked + dma_fence_signal_locked | - fence_default_wait + dma_fence_default_wait | - fence_add_callback + dma_fence_add_callback | - fence_remove_callback + dma_fence_remove_callback | - fence_enable_sw_signaling + dma_fence_enable_sw_signaling | - fence_is_signaled_locked + dma_fence_is_signaled_locked | - fence_is_signaled + dma_fence_is_signaled | - fence_is_later + dma_fence_is_later | - fence_later + dma_fence_later | - fence_wait_timeout + dma_fence_wait_timeout | - fence_wait_any_timeout + dma_fence_wait_any_timeout | - fence_wait + dma_fence_wait | - fence_context_alloc + dma_fence_context_alloc | - fence_array_create + dma_fence_array_create | - to_fence_array + to_dma_fence_array | - fence_is_array + dma_fence_is_array | - trace_fence_emit + trace_dma_fence_emit | - FENCE_TRACE + DMA_FENCE_TRACE | - FENCE_WARN + DMA_FENCE_WARN | - FENCE_ERR + DMA_FENCE_ERR ) ( ... ) Signed-off-by: Chris Wilson Reviewed-by: Gustavo Padovan Acked-by: Sumit Semwal Acked-by: Christian König Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20161025120045.28839-1-chris@chris-wilson.co.uk

drm/msm: move fence allocation out of msm_gpu_submit()

drm/msm: print offender task name on hangcheck recovery

2016-05-08T14:22:18Z

Track the pid per submit, so we can print the name of the task which submitted the batch that caused the gpu to hang. Signed-off-by: Rob Clark

drm/msm: drop return from gpu->submit()

2016-05-08T14:22:18Z

At this point, there is nothing left to fail. And submit already has a fence assigned and is added to the submit_list. Any problems from here on out are asynchronous (ie. hangcheck/recovery). Signed-off-by: Rob Clark
