Two BSpec updates changed the recommended values for BDW eDP and DP DDI buffer translations. Now the signal levels also match the HSW signal levels, which simplify things a little bit. It seems some DP sinks don't work properly without voltage level 0 and pre-emphasis level 3, so this patch may fix some bugs on panels/monitors that happen on BDW but not on HSW. Signed-off-by:

An object can only have an active gtt mapping if it is currently bound into the global gtt. Therefore we can simply walk the list of all bound objects and check the flag upon those for an active gtt mapping. From commit 48018a57 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Fri Dec 13 15:22:31 2013 -0200 drm/i915: release the GTT mmaps when going into D3 Also note that the WARN is inappropriate for this function as GPU activity is orthogonal to GTT mmap status. Rather it is the caller that relies upon this condition and so it should assert that the GPU is idle itself. References: https://bugs.freedesktop.org/show_bug.cgi?id=80081Signed-off-by:

The perfect solution for psr_exit is the hardware tracking the changes and doing the psr exit by itself. This scenario works for HSW and BDW with some environments like Gnome and Wayland. However there are many other scenarios that this isn't true. Mainly one right now is KDE users on HSW and BDW with PSR on. User would miss many screen updates. For instances any key typed could be seen only when mouse cursor is moved. So this patch introduces the ability of trigger PSR exit on kernel side on some common cases that. Most of the cases are coverred by psr_exit at set_domain. The remaining cases are coverred by triggering it at set_domain, busy_ioctl, sw_finish and mark_busy. The downside here might be reducing the residency time on the cases this already work very wall like Gnome environment. But so far let's get focused on fixinge issues sio PSR couild be used for everybody and we could even get it enabled by default. Later we can add some alternatives to choose the level of PSR efficiency over boot flag of even over crtc property. v2: remove exit from connector_dpms. Daniel pointed this is the wrong way and also this isn't needed for BDW and HSW anyway. Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by:

The DRM core will translate calls to legacy cursor ioctls into universal cursor calls automatically, so there's no need to maintain the legacy cursor support. This greatly simplifies the transition since we don't have to handle reference counting differently depending on which cursor interface was called. The aim here is to transition to the universal plane interface with minimal code change. There's a lot of cleanup that can be done (e.g., using state stored in crtc->cursor->fb rather than intel_crtc) that is left to future patches. v4: - Drop drm_gem_object_unreference() that is no longer needed now that we receive the GEM obj directly rather than looking up the ID. v3: - Pass cursor obj to intel_crtc_cursor_set_obj() if cursor fb changes, even if 'visible' is false. intel_crtc_cursor_set_obj() will notice that the cursor isn't visible and disable it properly, but we still need to get intel_crtc->cursor_addr set properly so that we behave properly if the cursor becomes visible again in the future without changing the cursor buffer (noted by Chris Wilson and verified via i-g-t kms_cursor_crc). - s/drm_plane_init/drm_universal_plane_init/. Due to type compatibility between enum and bool, everything actually works correctly with the wrong init call, except for the type of plane that gets exposed to userspace (it shows up as type 'primary' rather than type 'cursor'). v2: - Remove duplicate dimension checks on cursor - Drop explicit cursor disable from crtc destroy (fb & plane destruction will take care of that now) - Use DRM plane helper to check update parameters Cc: intel-gfx@lists.freedesktop.org Signed-off-by:

Refactor cursor buffer setting such that the code to actually update the cursor lives in a new function, intel_crtc_cursor_set_obj(), and takes a GEM object as a parameter. The existing legacy cursor ioctl handler, intel_crtc_cursor_set() will now perform the userspace handle lookup and then call this new function. This refactoring is in preparation for the universal plane cursor support where we'll want to update the cursor with an actual GEM buffer object (obtained via drm_framebuffer) rather than a userspace handle. v2: Drop obvious kerneldoc and replace with note about function's reference consumption Reviewed-by: -

Signed-off-by: -
Matt Roper authored
If drivers support universal planes and have registered a cursor plane with the DRM core, we should use that universal plane support when handling legacy cursor ioctls. Drivers that transition to universal planes won't have to maintain separate legacy ioctl handling; drivers that don't transition to universal planes will continue to operate without any change to behavior. Note that there's a bit of a mismatch between the legacy cursor ioctls and the universal plane API's --- legacy ioctl's use driver buffer handles directly whereas the universal plane API takes drm_framebuffers. Since there's no way to recover the driver handle from a drm_framebuffer, we can implement legacy ioctl's in terms of universal plane interfaces, but cannot implement universal plane interfaces in terms of legacy ioctls. Specifically, there's no way to create a general cursor helper in the way we previously created a primary plane helper. It's important to land this patch before any patches that add universal cursor support to individual drivers so that drivers don't have to worry about juggling two different styles of reference counting for cursor buffers when userspace mixes and matches legacy and universal cursor calls. With this patch, a driver that switches to universal cursor support may assume that all cursor buffers are wrapped in a drm_framebuffer and can rely on framebuffer reference counting for all cursor operations. v4: - Add comments pointing out setplane_internal's reference-eating semantics. v3: - Drop drm_mode_rmfb() call that is no longer needed now that we're using setplane_internal(), which takes care of deref'ing the appropriate framebuffer. v2: - Use new add_framebuffer_internal() function to create framebuffer rather than trying to call directly into the ioctl interface and look up the handle returned. - Use new setplane_internal() function to update the cursor plane rather than calling through the ioctl interface. Note that since we're no longer looking up an fb_id, no extra reference will be taken here. - Grab extra reference to fb under lock in !BO case to avoid issues where racing userspace could cause the fb to be destroyed out from under us after we grab the fb pointer.

We'll use this in a future patch when we implement legacy cursor ioctls on top of the universal plane interface. v3: - Move integer overflow checking from setplane_internal to setplane ioctl. The upcoming legacy cursor support via universal planes needs to maintain current cursor ioctl semantics and not return error for these extreme values (found via intel-gpu-tools kms_cursor_crc test). v2: - Allow planes to be disabled without a valid crtc again (and add mention of this to setplane's kerneldoc, since it doesn't seem to be mentioned anywhere else). - Reformat some parameter line wrap Reviewed-by:
