We already track the debugfs user_forcewake on the GT, so it is natural to pull the suspend/resume handling under gt/ as well. Signed-off-by:

Now that we split plane_state which I didn't want to do yet, we can program the slave plane without requiring the master plane. This is useful for programming bigjoiner slave planes as well. We will no longer need the master's plane_state. Changes since v1: - set src/dst rectangles after copy_uapi_to_hw_state. Changes since v2: - Use the correct color_plane for pre-gen11 by using planar_linked_plane != NULL. - Use drm_format_info_is_yuv_semiplanar in skl_plane_check() to fix gen11+. Signed-off-by:

Splitting plane state is easier than splitting crtc_state, before plane check we copy the drm properties to hw so we can do the same in bigjoiner later on. We copy the state after we did all the modeset handling, but fortunately i915 seems to be split correctly and nothing during modeset looks at plane_state. Changes since v1: - Do not clear hw state on duplication. Signed-off-by:

get_crtc_from_states() is called before plane_state is copied to uapi, so use the uapi state there. intel_legacy_cursor_update() could probably get away with looking at the hw state, but for clarity always look at the uapi state.

Maarten Lankhorst authored
Now that we separated everything into uapi and hw, it's time to make the split definitive. Remove the union and make a copy of the hw state on modeset and fastset. Color blobs are copied in crtc atomic_check(), right before color management is checked. Changes since v1: - Copy all blobs immediately after drm_atomic_helper_check_modeset(). - Clear crtc_state->hw on disable, instead of using clear_intel_crtc_state(). Changes since v2: - Use intel_crtc_free_hw_state + clear in intel_crtc_disable_noatomic(). - Make a intel_crtc_prepare_state() function that clears the crtc_state and copies hw members. - Remove setting uapi.adjusted_mode, we now have a direct call to drm_calc_timestamping_constants(). Changes since v3: - Rename prefix copy_hw_to_uapi_state() with intel_crtc. - Copy color blobs to uapi as well. - Add a intel_crtc_copy_uapi_to_hw_state_nomodeset() function for clarity. Changes since v4: - Copy hw.adjusted_mode back to uapi.adjusted_mode, to shut up the call to drm_calc_timestamping_constants() in drm_atomic_helper_update_legacy_modeset_state(). - Use drm_property_replace_blob (Ville). Changes since v5: - Use hw->mode in intel_modeset_readout_hw_state(). (Ville) - Copy to uapi.mode using drm_atomic_set_mode_for_crtc(). (Ville) Signed-off-by:

intel_get_load_detect_pipe() needs to set uapi active, uapi enable is set by the call to drm_atomic_set_mode_for_crtc(), so we can remove it. intel_pipe_config_compare() needs to look at hw state, but I didn't change spatch to look at it. It's easy enough to do manually. intel_atomic_check() definitely needs to check for uapi enable, otherwise intel_modeset_pipe_config cannot copy uapi state to hw. Changes since v1: - Actually set uapi.active in get_load_detect_pipe(). Signed-off-by:

Vanshidhar Konda asked for the simplest test "to verify that the kernel can submit and hardware can execute batch buffers on all the command streamers in parallel." We have a number of tests in userspace that submit load to each engine and verify that it is present, but strictly we have no selftest to prove that the kernel can _simultaneously_ execute on all known engines. (We have tests to demonstrate that we can submit to HW in parallel, but we don't insist that they execute in parallel.) v2: Improve the igt_spinner support for older gen. Suggested-by:

An interesting observation made with our parallel selftests was that on our small/single cpu systems we would call kthread_stop() before the kthreads were spawned. If this happens, the kthread is never run at all; completely bypassing the test. A simple yield() from the parent will ensure that all children have the opportunity to start before we reap them.

Intended for upstream testing so that we can still exercise the LMEM plumbing and !i915_ggtt_has_aperture paths. Smoke tested on Skull Canyon device. This works by allocating an intel_memory_region for a reserved portion of system memory, which we treat like LMEM. For the LMEMBAR we steal the aperture and 1:1 it map to the stolen region. To enable simply set the i915 modparam fake_lmem_start= on the kernel cmdline with the start of reserved region(see memmap=). The size of the region we can use is determined by the size of the mappable aperture, so the size of reserved region should be >= mappable_end. For now we only enable for the selftests. Depends on CONFIG_DRM_I915_UNSTABLE being enabled. eg. memmap=2G$16G i915.fake_lmem_start=0x400000000 v2: make fake_lmem_start an i915 modparam Signed-off-by:

In order to keep the assert_bind_count() valid, we need to hold the vma page reference until after we drop the bind count. However, we must also keep the drm_mm_remove_node() as the last action of i915_vma_unbind() so that it serialises with the unlocked check inside i915_vma_destroy(). So we need to split up i915_vma_remove() so that we order the detach, drop pages and remove as required during unbind. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=112067Signed-off-by:

When checking the heartbeat pulse, we expect it to have been sent by the time we have slept. We can verify this by checking the engine serial number to see if that matches the predicted pulse serial. It will always be true if, and only if, the pulse was sent by itself (as designed by the test). Signed-off-by:

GuC 35.2 for Gen12 is interface-compatible with 33.0 on older Gens, because the differences are related to additional blocks/commands in the interface to support new Gen12 features.

For the HPD interrupt functionality the HW depends on power wells in the display core domain to be on. Accordingly when enabling these power wells the HPD polling logic will force an HPD detection cycle to account for hotplug events that may have happened when such a power well was off. Thus a detect cycle started by polling could start a new detect cycle if a power well in the display core domain gets enabled during detect and stays enabled after detect completes. That in turn can lead to a detection cycle runaway. To prevent re-triggering a poll-detect cycle make sure we drop all power references we acquired during detect synchronously by the end of detect. This will let the poll-detect logic continue with polling (matching the off state of the corresponding power wells) instead of scheduling a new detection cycle.
