2018-02-12drm/etnaviv: remove the need for a gpu-subsystem DT nodeLucas Stach
The module autoloading can be triggered through the GPU core nodes and the necessary platform device for the DRM toplevel device will be instantiated on module init.

2018-02-12drm/etnaviv: hook up DRM GPU schedulerLucas Stach
This hooks in the DRM GPU scheduler. No improvement yet, as all the dependency handling is still done in etnaviv_gem_submit. This just replaces the actual GPU submit by passing through the scheduler. Allows to get rid of the retire worker, as this is now driven by the scheduler. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
2018-01-02drm/etnaviv: re-enable perfmon supportLucas Stach
Now that the PMR lifetime issues are solved we can safely re-enable performance counter profiling support. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
2018-01-02drm/etnaviv: move cmdbuf into submit objectLucas Stach
Less dynamic allocations and slims down the cmdbuf object to only the required information, as everything else is already available in the submit object. This also simplifies buffer and mappings lifetime management, as they are now exlusively attached to the submit object and not additionally to the cmdbuf.

2018-01-02drm/etnaviv: move workqueue to be per GPULucas Stach
While the etnaviv workqueue needs to be ordered, as we rely on work items being executed in queuing order, this is only true for a single GPU. Having a shared workqueue for all GPUs in the system limits concurrency artificially. Getting each GPU its own ordered workqueue still meets our ordering expectations and enables retire workers to run concurrently.

2017-10-22drm/etnaviv: short-circuit perfmon ioctlsLucas Stach
The feature implementation isn't stable yet. Reject any attempt to use the IOCTLs for now. This keeps most of the code in place, so we can stabilize it in-tree, but keeps userspace from using the feature for now. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

Make it possible that userspace can query all performance domains and its signals. This information is needed to sample those signals via submit ioctl.

into drm-next It includes code cleanups from Bhumika and Liviu, a significant shader performance fix and additions to the cmdstream validator from Wladimir and the addition of a cmdbuf suballocator by myself. The suballocator improves performance on all chips by reducing the CPU overhead of the kernel driver and side steps the GC3000 FE MMU flush erratum, now making the workarounds in IOVA allocation we had before unnecessary, which results in a nice cleanup of the code in that area. * 'drm-etnaviv-next' of https://git.pengutronix.de/git/lst/linux: drm/etnaviv: Remove duplicate header file include Revert "drm/etnaviv: trick drm_mm into giving out a low IOVA" drm/etnaviv: add cmdbuf suballocator drm/etnaviv: get cmdbuf physical address through the cmdbuf abstraction drm/etnaviv: wire up iova handling in new cmdbuf abstraction drm/etnaviv: move cmdbuf de-/allocation into own file drm/etnaviv: always flush MMU TLBs on map/unmap drm/etnaviv: constify etnaviv_iommu_ops structures drm/etnaviv: set up initial PULSE_EATER register drm/etnaviv: add new GC3000 sensitive states

2016-08-16drm: drop DRIVER_HAVE_IRQ flag for some driversShawn Guo
Since commit 4984979b9b90 ("drm/irq: simplify irq checks in drm_wait_vblank"), the drm driver feature flag DRIVER_HAVE_IRQ is only required for drivers that have an IRQ handler managed by the DRM core. Some drivers, armada, etnaviv, kirin and sti, set this flag without .irq_handler setup in drm_driver. These drivers manage IRQ handler by themselves and the flag DRIVER_HAVE_IRQ makes no sense there.

2016-06-21drm: Lobotomize set_busid nonsense for !pci driversDaniel Vetter
We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.
