If we reduce the suspend function for intel_opregion to do the minimum required, the resume function can also do the simple task of notifier the ACPI bios that we are back. This avoid some nasty restrictions on the likes of register_acpi_notifier() that are not allowed during the early phase of resume. v2: Keep the order of acpi notify vs turning off ardy/drdy the same.

Record the scratch PTE encoding upon creation rather than recomputing the bits everytime. This is important for the next patch where we forgo having a valid scratch page with which we may compute the bits and so require keeping the PTE value instead. v2: Fix up scrub_64K to use scratch_pte as well.

The vm of two contexts are supposed to be independent, such that a stray write by one cannot be detected by another. Normally the GTT is filled explicitly by userspace, but the space in between objects is filled with a scratch page -- and that scratch page should not be able to form an inter-context backchannel.

While checking the opportunity to add a display_gen check to allow glk and cnl to be on same bucket I noticed these FIXME cases here. So I got the confirmation from HW architect that we actually never needed this workaround. "GLK supports 2 pixel per clock, so pixel clock can be up to 2 * cdclk."

commit ac657f64 ("drm/i915: Introduce IS_GEN macro") introduced GEN_FOREVER that was never used. My first attempt was to rename it to FOREVER since GEN is already part of the macro. Then I used coccinelle to change all -INTEL_GEN(e1) >= e2 +INTEL_GEN_RANGE(e1, e2, FOREVER) -INTEL_GEN(e1) <= e2 +INTEL_GEN_RANGE(e1, 0, e2) and I liked it. However I didn't like very much the remaining INTEL_GEN(dev_priv) < n and: INTEL_GEN(e1) < n INTEL_GEN_RANGE(e1, 0, n - 1) didn't make much sense either. So INTEL_GEN use for > or < seems a better unified way for unlimited bounds. So, no reason to keep GEN_FOREVER here. Let's kill before someone start using it. v2: Remove remaining GEN_FOREVER forgotten in a comment. (Daniel) Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by:

In order to ensure that our system suspend and resume callbacks are called in the correct order wrt. those of the HDA driver add a device link to the HDA driver during audio component binding time. With i915 as the supplier and HDA as the consumer the PM framework will guarantee the HDA->i915 suspend (and shutdown) and i915->HDA resume order. Atm, the lack of this ordering is not a problem, since all the i915 suspend/resume steps that need to be ordered wrt. the HDA driver's suspend/resume steps are separated out to the i915 suspend_late/resume_early hooks. That will change in a follow-up patchset where we'll need this ordering guarantee for steps that are in the i915 suspend/resume hooks (and which can't be moved to suspend_late/resume_early for other reasons). So this patch is a preparation for that follow-up patchset. The change also allows us to move towards removing the i915 suspend_late/resume_early hooks alltogether. Since we only need to ensure the ordering during suspend/resume and not during driver probing create the link with DL_FLAG_STATELESS. Since the probe time ordering has to be optional we use the component framework for that. Similarly for runtime PM we depend on the audio driver getting/putting an i915 runtime PM reference whenever it needs it (along with the proper i915 display power domain) via the audio component ops get_power / put_power hooks. So we create the device link without DL_FLAG_PM_RUNTIME. v2: (Ville) - Add a note to the commit message about not using the device link runtime PM ordering. - Handle the error return from device_link_add().

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to the appropriate platforms. This was especially harsh on GLK since we don't even try to read the DIMM information on that platforms, hence valid_dimm was always false and thus we always tried to apply the w/a.

The first 3 planes (primary, sprite 0 and 1) have a dedicated chroma upsampler to upscale YUV420 to YUV444 and the scaler should only be used for upscaling. Because of this we shouldn't program the scalers in planar mode if NV12 and the chroma upsampler are used. Instead program the scalers like on normal planes. Sprite 2 and 3 have no dedicated scaler, and need to program the selected Y plane in the scaler mode. Changes since v1: - Make the comment less confusing. Changes since v2: - Fix checkpatch warning (Matt) - gen10- -> Pre-gen11 (Ville) - PS_SCALER_MODE_PACKED -> PS_SCALER_MODE_NORMAL.

Gen11 watermarks have a separate plane for Y and UV, with separate mechanisms.

To make NV12 working on icl, we need to update 2 planes simultaneously. I've chosen to do this in the CRTC step after plane validation is done, so we know what planes are (in)visible. The linked Y plane will get updated in intel_plane_update_planes_on_crtc(), by the call to update_slave, which gets the master's plane_state as argument. The link requires both planes for atomic_update to work, so make sure skl_ddb_add_affected_planes() adds both states. Changes since v1: - Introduce icl_is_nv12_y_plane(), instead of hardcoding sprite numbers. - Put all the state updating login in intel_plane_atomic_check_with_state(). - Clean up changes in intel_plane_atomic_check(). Changes since v2: - Fix intel_atomic_get_old_plane_state() to actually return old state. - Move visibility changes to preparation patch. - Only try to find a Y plane on gen11, earlier platforms only require a single plane. Changes since v3: - Fix checkpatch warning about to_intel_crtc() usage. - Add affected planes from icl_add_linked_planes() before check_planes(), it's a cleaner way to do this. (Ville) Changes since v4: - Clear plane links in icl_check_nv12_planes() for clarity. - Only pass crtc_state to icl_check_nv12_planes(). - Use for_each_new_intel_plane_in_state() in icl_check_nv12_planes. - Rename aux to linked.
