The vfio_info_add_capability() helper requires the caller to pass a capability ID, which it then uses to fill in header fields, assuming hard coded versions. This makes for an awkward and rigid interface. The only thing we want this helper to do is allocate sufficient space in the caps buffer and chain this capability into the list.

Add helper for initializing fbdev deferred I/O. The cleanup could have happened in drm_fb_helper_fini(), but that would have required me to set fb_info->fbdefio to NULL in a couple of drivers before they call _fini() to avoid double defio cleanup.

When attached to the connector, the mode_valid callback will only filter the modes provided by the connector itself as part of its probe. However, it will not be doing it when the mode is provided by the userspace, which still might result in a broken configuration.

2017-12-19drm/i915: Avoid context dereference inside execlists_submission_taskletChris Wilson2-4/+4
A lesson that has to be relearnt over and over again is that the request does not keep a reference to the context and so we cannot freely dereference the context from inside the execlists_submission_tasklet. In particular, we try to do so in the new GEM_TRACE() so convert those over to the port->context_id we keep for GEM debugging. This means the tracing now depends on DRM_I915_GEM_DEBUG.

2017-12-19drm/i915: Protect DDI port to DPLL map from theoretical race.Rodrigo Vivi1-0/+4
In case we have multiple modesets for different connectors happening in parallel we could have a race on the RMW on these shared registers. This possibility was initially raised by Paulo when reviewing commit '555e38d27317 ("drm/i915/cnl: DDI - PLL mapping")' but the original possibility comes from commit '5416d871136d ("drm/i915/skl: Set the eDP link rate on DPLL0")'. Or maybe later when atomic commits entered into picture. Apparently the discussion around this topic showed that the right solution would be on serializing the atomic commits in a way that we don't have the possibility of races here since if that parallel modeset happenings apparently many other things will be on fire. Code is there since SKL and there was no report of issue, but since we never looked back to that serialization possibility, and also we don't have an igt case for that it is better to at least protect this corner.

2017-12-19drm/i915: Add a strong mb to resetting the has-CS-interrupt bitChris Wilson1-1/+6
After a reset, the state of the CSB registers are scrubbed and not valid until a powercontext is reloaded. We only know when a powercontext has been reloaded once we see a CS-interrupt, before then we must ignore the CSB registers within the execlists_submission_tasklet. However, glk is sporadically dying with an illegal CSB pointer value (both in the HSWP and mmio) suggesting that it is running with the CS-interrupt bit set before the powercontext has been reloaded. Make sure the clearing of that bit is serialised on reset with the re-enabling of the tasklet.

2017-12-19gpu: ipu-v3: allow to build with COMPILE_TESTPhilipp Zabel3-1/+5
Add missing include <linux/sizes.h> in ipu-cpmem and ipu-ic, select BITREVERSE for ipu-cpmem and GENERIC_ALLOCATOR for ipu-pre, and allow to build if COMPILE_TEST is enabled. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-12-19drm/imx: advertise supported plane format modifiersLucas Stach1-1/+34
Let userspace know about the supported modifiers, to make automatic selection of a proper modifier possible. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-12-19drm/imx: add FB modifier supportLucas Stach2-6/+60
This adds FB modifier support for the Vivante single buffer tiled formats, when the PRG/PRE engines are present. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-12-19gpu: ipu-v3: prg: add modifier supportLucas Stach2-5/+12
Allow to pass through the modifier to the PRE unit and extend the format check with the supported modifiers. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2017-12-19gpu: ipu-v3: pre: add tiled prefetch supportLucas Stach3-6/+29
This configures the TPR unit, using the DRM format modifier. For now only the single buffer modifiers are supported, as split buffer needs more configuration for the required cropping.

2017-12-19drm: omapdrm: Simplify platform registrationAndrew F. Davis8-124/+36
Currently, calls into each file are used to register the various platform drivers. Change this to a table of pointers to platform_driver structs to allow using platform_register_drivers. Signed-off-by: Andrew F. Davis <afd@ti.com>
2017-12-19drm: omapdrm: Remove filename from header and fix copyright tagAndrew F. Davis54-106/+67
Having the filename in the header serves little purpose and is often wrong after renames as it is here in several places, just drop it from all omapdrm files. While we are here unify the copyright tags to the TI recommended style. Signed-off-by: Andrew F. Davis <afd@ti.com>
