The panel is similar to OSD101T2045-53TS (which is handled by panel-simple) with one big difference: osd101t2587-53ts needs MIPI_DSI_TURN_ON_PERIPHERAL message to be sent from the host to be operational and thus can not be handled by panel-simple.

Eric Anholt authored
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.

Eric Anholt authored
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.

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.

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.

The GFX IP is inside of the ASPEED BMC SoC so there is little use enabling it on a kernel that does not support ASPEED. When building with COMPILE_TEST the architecture many not have CMA support, so to avoid breaking the build we only select these options if the architecture supports the contiguous allocator.

Add support for 2MB sized pages. This will improve our map and unmap times and save a bit of memory by avoiding 3rd level page tables for contiguous allocations. As we use shmem for buffers and huge page allocations for shmem are off by default, there isn't an improvement out of the box and userspace must enable THP for shmem. It's not clear if the h/w can support 1GB page sizes which standard ARM long format descriptors support. In any case, it is unlikely we'll see any contiguous 1GB allocations on current h/w.
