As we may like to use a bisection search on the tables in future, we need them to be ordered. For convenience we expect the compiled tables to be order and check on initialisation. However, the validator used the wrong iterators failed to spot the misordered MI tables and instead walked off into the unknown (as spotted by kasan). Signed-off-by:

In the future, we may want to speed up command/register searching using a bisection and so we require them to be in ascending order respectively by command value or register address. However, this was not true for one pair in the MI table; make it so. Signed-off-by:

When we shrink our working sets, we want to avoid stealing pages from objects that likely to be reused in the near future. We first look at inactive objects before processing active objects - but what about a recently active object that is about to be used again. That object's position in the bound_list is ordered by the time of binding, not the time of last use, so the most recently used inactive object could well be at the head of the shrink list. To compensate, give the object a bump to MRU when it becomes inactive (thus transitioning to the end of the first pass in shrink lists). Conversely, bumping on inactive makes bumping on active useless, since when we do have to reap from the active working set, everything is going to become inactive very quickly and the order pretty much random - just hope for the best at that point, as once we start stalling on active objects, we can hope that the rebinding neatly orders vital objects.

Remove the leftovers, yay! AGP for i915 kms died long ago with commit 3bb6ce66 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Nov 13 22:14:16 2013 +0100 drm/i915: Kill legeacy AGP for gen3 kms and with ums now gone to there's really no users any more. Note that device_is_agp is only called when DRIVER_USE_AGP is set and since we've unconditionally cleared that since a while there are really no users left for i915_driver_device_is_agp. Reviewed-by:

Chris rightfully suggested that documenting fences without documenting the BO tiling tracking doesn't make much sense, so fix that. The important bit to stress here (since it lead to some confusion) is the GEM doesn't really care about tiling. Except for a few select cases where the kernel needs to manage something that userspace can't take care of: Namely the limited number of fences and fixing up swizzling, although we still fail at the later. v2: Move the low-level tiling/swizzling functions and kerneldoc to i915_gem_fence.c and leave only the userspace interface here. Suggested by Chris. Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by:

It fits more with the low-level fence code, and this move leaves only the userspace tiling ioctl handling in i915_gem_tiling.c. Suggested-by:

Sorting became confused and a few new files ended up in strange places. Also move i915_irq.c to core since with the recent-ish extraction of i915_gpu_error.c and intel_hotplug.c it's more and more really just basic irq handling code. When adding new files please don't put them somewhere randomly. Acked-by:

Imre Deak authored
Currently HPD_PORT_A is used as an alias for HPD_NONE to mean that the given port doesn't support long/short HPD pulse detection. SDVO and CRT ports are like this and for these ports we only want to know whether an hot plug event was detected on the corresponding pin. Since at least on BXT we need long/short pulse detection on PORT A as well (added by the next patch) remove this aliasing of HPD_PORT_A/HPD_NONE and let the return value of intel_hpd_pin_to_port() show whether long/short pulse detection is supported on the passed in pin.

While creating the debugfs file we are setting the inode->i_private to dev. That same dev is passed to these functions as private of struct seq_file via single_open().

The Golden batch carries 3D state at the beginning so that HW starts with a known state. It is carried as a binary blob which is auto-generated from source. The idea was it would be easier to maintain and keep the complexity out of the kernel which makes sense as we don't really touch it. However if you really need to update it then you need to update generator source and keep the binary blob in sync with it. There is a need to patch this in bxt to send one additional command to enable a feature. A solution was to patch the binary data with some additional data structures (included as part of auto-generator source) but it was unnecessarily complicated. Chris suggested the idea of having a secondary batch and execute two batch buffers. It has clear advantages as we needn't touch the base golden batch, can customize secondary/auxiliary batch depending on Gen and can be carried in the driver with no dependencies. This patch adds support for this auxiliary batch which is inserted at the end of golden batch and is completely independent from it. Thanks to Mika for the preliminary review. v2: Strictly conform to the batch size requirements to cover Gen2 and add comments to clarify overflow check in macro (Chris, Mika). v3: aux_batch_offset was declared as u64, change it to u32 (Chris) Reviewed-by:

intel_guc_fwif.h contains the subset of the GuC interface that we will need for submission of commands through the GuC. These MUST be kept in sync with the definitions used by the GuC firmware, and updates to this file will (or should) be autogenerated from the source files used to build the firmware. Editing this file is therefore not recommended. i915_guc_reg.h contains definitions of GuC-related hardware: registers, bitmasks, etc. These should match the BSpec. v2: Files renamed & resliced per review comments by Chris Wilson v4: Added DON'T-EDIT-ME warning [Tom O'Rourke] Issue: VIZ-4884 Signed-off-by:Alex Dai <yu.dai@intel.com> Signed-off-by:

This reverts commit 6adfb1ef. Ironlake RPS code runs under an irqsave spinlock and hence sleeping isn't allowed. Not a this long delay while blocking irqs isn't great at all, but fixing the locking scheme is a lot more involved. So just revert for now.

on SKL/BXT, the top most plane hardware is shared between the legacy cursor registers and an actual plane. Daniel and Ville don't want to expose 2 DRM planes and would rather expose a CURSOR plane that has all the usual plane properties, and that's a blocker for lifting the prelimary_hw_support flag. Unfortunately noone has had the time to finish this yet, but lifting the prelimary_hw_support flag is long overdue. As an intermediate solution we can merely not expose the top most plane Cc: Imre Deak <imre.deak@intel.com> Signed-off-by:

Fastboot should only downgrade a modeset if we have a match, not be used to upgrade to a full modeset. Otherwise we can only use it in a very restricted way: Initial modeset when the request mode is the preferred one of the panel and there's still a pfit active. And that only works because our mode_from_pipe_config fills in the wrong mode (it takes the adjusted mode, not the requested one). But we want fast modesets everywhere even after boot-up (especially for testing, but not only there). Hence we need to be able to make any modeset a fast one, which means we need to invert the logic and optionally downgrade a modeset. Note that this needs ->connector_changed split out from ->mode_changed otherwise it's not going to work (because we might loose a modeset because connectors changed but otherwise the config matches). As soon as that's merged we can drop the i915.fastboot check from this code. Also make sure that we don't accidentally clear any_ms and that we add the planes for any kind of modeset. Finally rename fastboot to fastset (yeah it's a silly name) since this really isn't about booting all that much. Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by:

Currently we both set mode->private_flags to some value and also use the pipe_config quirk. But since the pipe_config quirk isn't tied to the lifetime of the mode object we need to check both. Simplify this by only using mode.private_flags and stop using the INHERITED_MODE quirk. Also for clarity add an explicit #define for that driver priavete mode flag. By using crtc_state->mode_changed we can also remove the recalc local variable. Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by:
