2016-11-24drm/i915/gvt: fix getting 64bit bar size errorXiaoguang Chen1-0/+2
For 64bit bar while reading the higher 32bit the value should be returned directly. In the current implementation the higher 32bit value was discarded and not written to the cfg space of vgpu which lead to an incorrect bar size.

2016-11-18drm/i915: Always flush the dirty CPU cache when pinning the scanoutChris Wilson2-11/+13
Currently we only clflush the scanout if it is in the CPU domain. Also flush if we have a pending CPU clflush. We also want to treat the dirtyfb path similar, and flush any pending writes there as well. v2: Only send the fb flush message if flushing the dirt on flip v3: Make flush-for-flip and dirtyfb look more alike since they serve similar roles as end-of-frame marker.

2016-11-18drm/i915: Be more careful to drop the GT wakerefChris Wilson1-8/+9
Since we can retire requests from multiple paths, we cannot assume that i915_gem_retire_requests() is the sole path on which we can transition to gt.active_requests == 0. A consequence of this is that we would skip the function if we had already retired all the requests and not scheduled the idle worker. This is fallout from changing the routine from considering active_engines (for which it was the only consumer) to active_requests. v2: Move kicking the idle working to i915_gem_request_retire() otherwise we could postpone the idle callback everytime we called retire_requests even though we did no work. v3: We only need to move the idle work kicking! v4: Drop the BUG_ON(!awake) as we may be called from the shrinker in the middle of constructing a request before we have marked the device awake. v5: Add a BUG_ON() for active_requests underflow upon retirement (Joonas) Fixes: 28176ef4cfa5 ("drm/i915: Reserve space in the global seqno during request allocation") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20161115164620.17185-1-chris@chris-wilson.co.uk Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
2016-11-18drm/i915: Move frontbuffer CS write tracking from ggtt vma to objectChris Wilson7-20/+19
I tried to avoid having to track the write for every VMA by only tracking writes to the ggtt. However, for the purposes of frontbuffer tracking this is insufficient as we need to invalidate around writes not just to the the ggtt but all aliased ppgtt views of the framebuffer. By moving the critical section to the object and only doing so for framebuffer writes we can reduce the tracking even further by only watching framebuffers and not vma.

2016-11-17drm/i915: make i915 the source of acpi device ids for _DODJani Nikula2-64/+27
The graphics driver is supposed to define the DIDL, which are used for _DOD, not the BIOS. Restore that behaviour. This is basically a revert of commit 3143751ff51a163b77f7efd389043e038f3e008e Author: Zhang Rui <rui.zhang@intel.com> Date: Mon Mar 29 15:12:16 2010 +0800 drm/i915: set DIDL using the ACPI video output device _ADR method return. which went out of its way to cater to a specific BIOS, setting up DIDL based on _ADR method. Perhaps that approach worked on that specific machine, but on the machines I checked the _ADR method invents the device identifiers out of thin air if DIDL has not been set. The source for _ADR is also supposed to be the DIDL set by the driver, not the other way around. With this, we'll also limit the number of outputs to what the driver actually has. A side effect of this change is that the DIDL, and by proxy CADL, will be initialized in the order of the connector list. That, in turn, has internal panels in front, ensuring they're included in the DIDL and CADL lists. Hopefully this ensures the BIOS does not block backlight hotkey events, thinking the internal panel is off. v2: do not set ACPI_DEVICE_ID_SCHEME in the device id (Peter Wu) v3: Rebase Cc: Peter Wu <peter@lekensteyn.nl> Cc: Rainer Koenig <Rainer.Koenig@ts.fujitsu.com> Cc: Jan-Marek Glogowski <glogow@fbihome.de> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Marcos Paulo de Souza <marcos.souza.org@gmail.com> Cc: Paolo Stivanin <paolostivanin@fastmail.fm> Tested-by: Rainer Koenig <Rainer.Koenig@ts.fujitsu.com> Tested-by: Paolo Stivanin <paolostivanin@fastmail.fm> Tested-by: Marcos Paulo de Souza <marcos.souza.org@gmail.com> Reviewed-and-tested-by: Peter Wu <peter@lekensteyn.nl> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/9660d29cf310c17bbf4d58c0e09d5b047446e2d5.1479295490.git.jani.nikula@intel.com
2016-11-17drm/i915: fix the dequeue logic for single_port_submission contextMin He1-1/+2
For a single_port_submission context, GVT expects that it can only be submitted to port 0, and there shouldn't be any other context in port 1 at the same time. This is required by GVT-g context to have an opportunity to save/restore some non-hw context render registers. This patch is to workaround GVT-g. v2: optimized code by following Chris's advice, and added more comments to explain the patch. v3: followed the coding style.

FS threading brings performance improvements of 0-20% in glmark2. The validation code checks for thread switch signals and ensures that the registers of the other thread are not touched, and that our clamps are not live across thread switches. It also checks that the threading and branching instructions do not interfere. (Original patch by Jonas, changes by anholt for style cleanup, removing validation the kernel doesn't need to do, and adding the flag for userspace). v2: Minor style fixes from checkpatch.

Avoid requiring struct_mutex for exclusive access to the temporary dfs_link inside the i915_dependency as not all callers may want to touch struct_mutex.

2016-11-16drm/fence: add out-fences supportGustavo Padovan5-45/+211
Support DRM out-fences by creating a sync_file with a fence for each CRTC that sets the OUT_FENCE_PTR property. We use the out_fence pointer received in the OUT_FENCE_PTR prop to send the sync_file fd back to userspace. The sync_file and fd are allocated/created before commit, but the fd_install operation only happens after we know that commit succeed. v2: Comment by Rob Clark: - Squash commit that adds DRM_MODE_ATOMIC_OUT_FENCE flag here.
