2019-04-18drm/v3d: Add missing implicit synchronization.Eric Anholt3-61/+53
It is the expectation of existing userspace (X11 + Mesa, in particular) that jobs submitted to the kernel against a shared BO will get implicitly synchronized by their submission order. If we want to allow clever userspace to disable implicit synchronization, we should do that under its own submit flag (as amdgpu and lima do). Note that we currently only implicitly sync for the rendering pass, not binning -- if you texture-from-pixmap in the binning vertex shader (vertex coordinate generation), you'll miss out on synchronization. Fixes flickering when multiple clients are running in parallel, particularly GL apps and compositors. v2: Fix a missing refcount on the CSD done fence for L2 cleaning.

2019-04-18drm/v3d: Add support for compute shader dispatch.Eric Anholt9-19/+503
The compute shader dispatch interface is pretty simple -- just pass in the regs that userspace has passed us, with no CLs to run. However, with no CL to run it means that we need to do manual cache flushing of the L2 after the HW execution completes (for SSBO, atomic, and image_load_store writes that are the output of compute shaders). This doesn't yet expose the L2 cache's ability to have a region of the address space not write back to memory (which could be used for shared_var storage). So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing the ES31 tests), and on the kernel side on 7278 (failing atomic compswap tests in a way that doesn't reproduce on simpenrose). v2: Fix excessive allocation for the clean_job (reported by Dan Carpenter). Keep refs on jobs until clean_job is finished, to avoid spurious MMU errors if the output BOs are freed by userspace before L2 cleaning is finished.

2019-04-18drm/v3d: Refactor job management.Eric Anholt4-329/+380
The CL submission had two jobs embedded in an exec struct. When I added TFU support, I had to replicate some of the exec stuff and some of the job stuff. As I went to add CSD, it became clear that actually what was in exec should just be in the two CL jobs, and it would let us share a lot more code between the 4 queues. v2: Fix missing error path in TFU ioctl's bo[] allocation.

2019-04-18drm/sun4i: Use DRM_GEM_CMA_VMAP_DRIVER_OPS for GEM operationsPaul Kocialkowski1-15/+1
Our driver makes a typical use of CMA, with GEM object allocated as GEM CMA objects. Use DRM_GEM_CMA_VMAP_DRIVER_OPS to describe the ops instead of duplicating them. Because DRM_GEM_CMA_VMAP_DRIVER_OPS implements a gem_create_object op which sets per-object funcs (drm_cma_gem_default_funcs), we can also get rid of free_object_unlocked and gem_vm_ops, which are superseded by the object funcs.

2019-04-12iommu: io-pgtable: Add ARM Mali midgard MMU page table formatRob Herring2-22/+70
ARM Mali midgard GPU is similar to standard 64-bit stage 1 page tables, but have a few differences. Add a new format type to represent the format. The input address size is 48-bits and the output address size is 40-bits (and possibly less?). Note that the later bifrost GPUs follow the standard 64-bit stage 1 format. The differences in the format compared to 64-bit stage 1 format are: The 3rd level page entry bits are 0x1 instead of 0x3 for page entries. The access flags are not read-only and unprivileged, but read and write. This is similar to stage 2 entries, but the memory attributes field matches stage 1 being an index. The nG bit is not set by the vendor driver. This one didn't seem to matter, but we'll keep it aligned to the vendor driver.

2019-04-12drm/bridge: ti-tfp410: Set the bus_formatPeter Ujfalusi1-0/+17
The TFP410 supports 24 bit, single-edge and 12 bit, dual-edge modes. Depending on how many wires are used (24/12) the driver can set the correct bus_format. If the information is not available in DT then assume 24 bit, single-edge setup.

2019-04-11drm/sun4i: Rely on dma interconnect for our RAM offsetMaxime Ripard1-7/+21
Now that we can express our DMA topology, rely on those property instead of hardcoding an offset from the dma_addr_t which wasn't really great. We still need to add some code to deal with the old DT that would lack that property, but we move the offset to the DRM device dma_pfn_offset to be able to rely on just the dma_addr_t associated to the GEM object.

While switching to the Common Clock Framework is still Work In Progress, this patch adds the corresponding G12A HDMI PLL setup to be on-par with the other SoCs support. The G12A has only a single tweak about the high frequency setup, where the HDMI PLL needs a specific setup to handle correctly the 5.94GHz DCO frequency. Apart that, it handls ecorrectly all the other HDMI frequencies and can achieve even better DMT clock frequency precision with the larger fractional dividier width.
