Do to the move active/inactive lists, it no longer makes sense to use them for shrinking, since shrinking isn't VM specific (such a need may also exist, but doesn't yet). What we can do instead is use the global bound list to find all objects which aren't active. Signed-off-by:

Earlier in the conversion sequence we attempted to quickly wedge in the transitional interface as static inlines. Now that we're sure these interfaces are sane, for easier debug and to decrease code size (since many of these functions may be called quite a bit), make them real functions While at it, kill off the set_color interface. We'll always have the VMA, or easily get to it. Signed-off-by:

Move all the similar address space (VM) initialization code to one function. Until we have multiple VMs, there should only ever be 1 VM. The aliasing ppgtt is a special case without it's own VM (since it doesn't need it's own address space management). Signed-off-by:

The default LLC age was changed: commit 0d8ff15e Author: Ben Widawsky <benjamin.widawsky@intel.com> Date: Thu Jul 4 11:02:03 2013 -0700 drm/i915/hsw: Set correct Haswell PTE encodings. On the surface it would seem setting a default age wouldn't matter because all GEM BOs are aged similarly, so the order in which objects are evicted would not be subject to aging. The current working theory as to why this caused a regression though is that LLC is a bit special in that it is shared with the CPU. Presumably (not verified) the CPU fetches cachelines with age 3, and therefore recently cached GPU objects would be evicted before similar CPU object first when the LLC is full. It stands to reason therefore that this would negatively impact CPU bound benchmarks - but those seem to be low on the priority list. eLLC OTOH does not have this same property as LLC. It should be used entirely for the GPU, and so the age really shouldn't matter. Furthermore, we have no evidence to suggest one is better than another on eLLC. Since we've never properly supported eLLC before no, there should be no regression. If the GPU client really wants "younger" objects, they should use MOCS. v2: Drop the extra #define (Chad) v3: Actually git add v4: Pimped commit message Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=67062Signed-off-by:

Userspace can pass a mode with an unspecified vsync/hsync polarity setting. All encoders in the Intel driver take this to mean a negative polarity setting. The HW readout/state checker code on the other hand needs these flags to be explicitly set, otherwise the state checker will WARN about the mismatch. Get rid of the WARN by making the polarity setting explicit in the adjusted mode flags based on the requested mode flags. This will keep the existing behavior otherwise. Note that we could guess from the other timing parameters whether the user wanted a VESA or other standard mode and set the polarity accordingly. This is what the NV driver does (drivers/gpu/drm/nouveau/dispnv04/crtc.c), but I think that's not very exact and would change the existing behavior of the Intel driver.

VLV wants encoder enabling before the pipe is up. With the previously rearranged VLV DP and HDMI ->pre_enable and ->enable callbacks in place, this no longer depends on the early ->enable hook call. Move the ->enable call at the end of the sequence, similar to the crtc enable on other platforms. This will be needed e.g. for moving the eDP backlight enabling to the right place in the sequence, currently done too early on VLV. There should be no functional changes. v2: Rebase. v3: Explain why this is needed in the commit message (Chris). Signed-off-by:

VLV wants encoder enabling before the pipe is up. This is currently achieved through calling the ->enable callback early, right after the ->pre_enable callback, in valleyview_crtc_enable(). This loses both the distinction between ->pre_enable and ->enable on VLV and the possibility to use a hook at the end of the modeset sequence. Rearrange the HDMI callbacks to make it possible to move ->enable call later. Basically do everything in ->pre_enable on VLV, and make ->enable a NOP.

SNB and IVB have slightly a different way to read out the watermark latency values. Signed-off-by:
-
Ville Syrjälä authored
The LP1+ watermark latency values need to be multiplied by 5 to make them suitable for watermark calculations. However on pre-HSW platforms we're going to need the raw value later when we have to write it to the WM_LPn registers' latency field. So delay the multiplication until it's needed. Note: Paulo complains that the units of wm (now in 100ns) aren't really clear and I agree. But that can be fixed later on ... Signed-off-by:

Move parsing of MCH_SSKPD to a separate function, we'll add other platforms there later. Note: Chris spotted an empty struct initializer and wondered whether that is hiding a compilier warning. Ville explained that it should have been part of the patch that extends this function to snb/ivb, which don't have all levels hsw has. I've figured it's ok to keep it here with a small note.

The PTE layouts are the same for both ppgtt and gtt, so we can simplify the setup for ppgtt by copying the encoding function pointer from gtt. This prevents bugs where we update one function pointer, but forget the other.

Almost invariably the reason why FBC cannot be turned on is the same every time (disabled via parameter, too many pipes, pipe too large etc) as modesetting and framebuffer configuration changes less frequently than trying to enable FBC. Signed-off-by:

In the old days of the crtc helpers we've only had the encoder and crtc ->mode_fixup callbacks. So when the lvds connector wanted to adjust the crtc timings it had to set a driver-private mode flag to tell the crtc mode fixup code to not overwrite them with the generic ones. When converting things to the new infrastructure I've kept the entire logic and only moved the flag to pipe_config->timings_set. But this logic is pretty tricky and already caused regressions: commit 21d8a475 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 12 08:07:30 2013 +0200 drm/i915: fix pfit regression for non-autoscaled resolutions So take advantage of the flexibility our own modeset infrastructure affords us and prefill default crtc timings. This allows us to rip out ->timings_set. Note that we overwrite things again when retrying the pipe config computation due to bandwidth constraints to avoid bogus crtc timings if the encoder only does relative adjustments (which is how the pfit code works). Only a theoretical concern though since platforms where we retry (pch-split platforms) do not need adjustements (since only the old gmch pfit needs that). But let's better be safe than sorry. Since we now initialize the crtc timings before calling the encoder->compute_config functions the crtc initialization in the gmch pfit code is now redudant and so can be removed.

This is the last encoder ->mode_fixup callback we have left, so convert it. Note that we want to only rip out the encoder->mode_fixup callback. But we still have the dvo_slave->mode_fixup callback. dvo is gen2 only, so we won't ever touch this again. Hence why I didn't go through all 6-7 dvo slave drivers and give them the same treatment. I'll add a note to the commit message about this when merging, presuming there's nothing else in the patch that needs to be fixed up. Reviewed-by:
