2018-05-03drm/i915/icl: Add configuring MOCS in new Icelake enginesTomasz Lis
In Icelake, there are more engines on which Memory Object Control States need to be configured. Besides adding Icelake under Skylake config, the patch makes sure MOCS register addresses for the new engines are properly defined. Additional patch might be need later, in case the specification will propose different MOCS config values for Icelake than in previous gens. v2: Restricted comments to gen11, updated description, renamed defines. v3: Used proper engine indexes for gen11. v4: Ensure patch is Icelake only. v5: Style fixes (proposed by mwajdeczko) v6 (from Paulo): fix checkpatch's COMMIT_LOG_LONG_LINE (Checkpatch).

2018-05-03drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+Eric Anholt
This driver will be used to support Mesa on the Broadcom 7268 and 7278 platforms. V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's complicated CL/shader validation scheme. This massively changes the GEM behavior, so I've forked off to a new driver. v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild test robot. Drop personal git link from MAINTAINERS. Don't double-map dma-buf imported BOs. Add kerneldoc about needing MMU eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup to mmap time. Use drm_dev_init instead of _alloc. Use ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage, since we don't modeset. Switch page tables back to WC (debug change to coherent had slipped in). Switch drm_gem_object_unreference_unlocked() to drm_gem_object_put_unlocked(). Simplify overflow mem handling by not sharing overflow mem between jobs. v3: no changes v4: align submit_cl to 64 bits (review by airlied), check zero flags in other ioctls.

2018-05-03drm/vc4: Add a pad field to align drm_vc4_submit_cl to 64 bits.Eric Anholt
I had originally asked Stefan Schake to drop the pad field from the syncobj changes that just landed, because I couldn't come up with a reason to align to 64 bits. Talking with Dave Airlie about the new v3d driver's submit ioctl, we came up with a reason: sizeof() on 64-bit platforms may align to 64 bits, in which case the userspace will be submitting the aligned size and the final 32 bits won't be zero-padded by the kernel. If userspace doesn't zero-fill, then a future ABI change adding a 32-bit field at the end could potentially cause the kernel to read undefined data from old userspace (our userspace happens to use structure initialization that zero-fills, but as a general rule we try not to rely on that in the kernel).

2018-05-03drm/i915: Correctly populate user mode h/vdisplay with pipe src size during ↵Ville Syrjälä
readout During state readout we first read out the pipe src size, store that information in the user mode h/vdisplay, but later on we overwrite that with the actual crtc timings. That makes our read out crtc state inconsistent with itself when the BIOS has enabled the panel fitter to scale the pipe contents. Let's preserve the pipe src size based information in the user mode to make things consistent again. This fixes a problem introduced by commit a2936e3d9a9c ("drm/i915: Use drm_mode_get_hv_timing() to populate plane clip rectangle") where the inconsistent state is now leading the plane clipping code to report a failure on account the plane dst coordinates not matching the user mode size. Previously we did the plane clipping based on the pipe src size instead and thus never noticed the inconsistency. The failure manifests as a WARN: [ 0.762117] [drm:intel_dump_pipe_config [i915]] requested mode: [ 0.762142] [drm:drm_mode_debug_printmodeline [drm]] Modeline 0:"1366x768" 60 72143 1366 1414 1446 1526 768 771 777 784 0x40 0xa ...

pipe update No functional changes, just a minor knit. Stumbled across the kernel doc for schedule_timeout() which quotes "In all cases the return value is guaranteed to be non-negative".

2018-05-03drm/i915: Adjust eDP's logical vco in a reliable place.Rodrigo Vivi
On intel_dp_compute_config() we were calculating the needed vco for eDP on gen9 and we stashing it in intel_atomic_state.cdclk.logical.vco However few moments later on intel_modeset_checks() we fully replace entire intel_atomic_state.cdclk.logical with dev_priv->cdclk.logical fully overwriting the logical desired vco for eDP on gen9.

2018-05-03dma-fence: Allow wait_any_timeout for all fencesDaniel Vetter
When this was introduced in commit a519435a96597d8cd96123246fea4ae5a6c90b02 Author: Christian König <christian.koenig@amd.com> Date: Tue Oct 20 16:34:16 2015 +0200 dma-buf/fence: add fence_wait_any_timeout function v2 there was a restriction added that this only works if the dma-fence uses the dma_fence_default_wait hook. Which works for amdgpu, which is the only caller. Well, until you share some buffers with e.g. i915, then you get an -EINVAL. But there's really no reason for this, because all drivers must support callbacks. The special ->wait hook is only as an optimization; if the driver needs to create a worker thread for an active callback, then it can avoid to do that if it knows that there's a process context available already. So ->wait is just an optimization, just using the logic in dma_fence_default_wait() should work for all drivers. Let's remove this restriction.

2018-05-02drm/i915: Split i915_gem_timeline into individual timelinesChris Wilson
We need to move to a more flexible timeline that doesn't assume one fence context per engine, and so allow for a single timeline to be used across a combination of engines. This means that preallocating a fence context per engine is now a hindrance, and so we want to introduce the singular timeline. From the code perspective, this has the notable advantage of clearing up a lot of mirky semantics and some clumsy pointer chasing. By splitting the timeline up into a single entity rather than an array of per-engine timelines, we can realise the goal of the previous patch of tracking the timeline alongside the ring. v2: Tweak wait_for_idle to stop the compiling thinking that ret may be uninitialised.

2018-05-02drm/i915: Move timeline from GTT to ringChris Wilson
In the future, we want to move a request between engines. To achieve this, we first realise that we have two timelines in effect here. The first runs through the GTT is required for ordering vma access, which is tracked currently by engine. The second is implied by sequential execution of commands inside the ringbuffer. This timeline is one that maps to userspace's expectations when submitting requests (i.e. given the same context, batch A is executed before batch B).

2018-05-02drm/pl111: Enable device-specific assigned memoryLinus Walleij
The Versatile Express has 8 MB of dedicated video RAM (VRAM) on the motherboard, which is what we should be using for the PL111 if available. On this platform, the memory backplane is constructed so that only this memory will work properly with the CLCD on the motherboard, using any other memory area just gives random snow on the display. The CA9 Versatile Express also has a PL111 instance on its core tile that can address all memory, and this does not have the restriction. The memory is assigned to the device using the memory-region device tree property and a "shared-dma-pool" reserved memory pool like this: reserved-memory { #address-cells = <1>; #size-cells = <1>; ranges; vram: vram@48000000 { compatible = "shared-dma-pool"; reg = <0x48000000 0x00800000>; no-map; }; }; clcd@1f000 { compatible = "arm,pl111", "arm,primecell"; (...) memory-region = <&vram>; }·; Cc: Liviu Dudau <liviu.dudau@arm.com> Cc: Mali DP Maintainers <malidp@foss.arm.com> Reviewed-by: Eric Anholt <eric@anholt.net> Tested-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20180502134719.8388-2-linus.walleij@linaro.org
2018-05-02drm/pl111: Support the Versatile ExpressLinus Walleij
The Versatile Express uses a special configuration controller deeply embedded in the system motherboard FPGA to multiplex the two to three (!) display controller instances out to the single SiI9022 bridge. Set up an extra file with the logic to probe to the FPGA mux register on the system controller bus, then parse the device tree to see if there is a CLCD or HDLCD instance on the core tile (also known as the daughterboard) by looking in the root of the device tree for compatible nodes. - If there is a HDLCD on the core tile, and there is a driver for it, we exit probe and deactivate the motherboard CLCD. We do not touch the DVI mux in this case, to make sure we don't break HDLCD. - If there is a CLCD on both the motherboard and the core tile (only the CA9 has this) the core tile CLCD takes precedence and get muxed to the DVI connector. - Only if there is no working graphics on the core tile, the motherboard CLCD is probed and muxed to the DVI connector. Core tile graphics should always take precedence as it can address all memory and is also faster, however the motherboard CLCD is good to have around for diagnostics and testing. It is possible to test the motherboard CLCD by setting the status = "disabled" property on the core tile CLCD or HDLCD. Scale down the Versatile Express to 16BPP so we can support a 1024x768 display despite the bus bandwidth restrictions on this platform. (The motherboard CLCD supports slightly lower resolution.)

Enabling the extra warnings also enabled some additional clang-only warnings, as a result building i915 with clang currently is extremely noisy. For now also disable the clang warnings sign-compare, sometimes-uninitialized, unneeded-internal-declaration and initializer-overrides.

This semantic mismatch lead to us falsely claiming a time out occurred.

2018-04-30drm/vc4: Make sure vc4_bo_{inc,dec}_usecnt() calls are balancedBoris Brezillon
Commit b9f19259b84d ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl") introduced a mechanism to mark some BOs as purgeable to allow the driver to drop them under memory pressure. In order to implement this feature we had to add a mechanism to mark BOs as currently used by a piece of hardware which materialized through the ->usecnt counter. Plane code is supposed to increment usecnt when it attaches a BO to a plane and decrement it when it's done with this BO, which was done in the ->prepare_fb() and ->cleanup_fb() hooks. The problem is, async page flip logic does not go through the regular atomic update path, and ->prepare_fb() and ->cleanup_fb() are not called in this case. Fix that by manually calling vc4_bo_{inc,dec}_usecnt() in the async-page-flip path. Note that all this should go away as soon as we get generic async page flip support in the core, in the meantime, this fix should do the trick.
