cdclk_compute_crawl_and_squash_midpoint() was still assuming that cd2x divider == 1 (ie. full divider == 2). Remove that assumption by computing the dividers properly. We'll also toss in a WARN in case the divider somehow ends up different between the old and new cdclk configs. That should never happen given we have div==2 in all the cdclk table entries for the affected platforms. If in the future we need a config where the divider also needs to be changed then we likely need to add an extra step into the cdclk programming sequence to make sure things stay within legal limits throughout the process.

There's nothing magical about vlv+ platforms vs. fastboot. If it works somewhere it should work everywhere, assuming we've not missed any crucial state checks. That seems unlikely on older platforms with less state to check anyway. Just enable fastboot across the board, and the remove the remnants of the optional stuff (we already removed the modparam for fastboot anyway). Signed-off-by:

Prevent accessing the HW from the get_modes hooks of connectors deriving the mode list from the display's EDID. drm_edid_connector_add_modes() will return the mode list based on the EDID which was cached during a previous detection/get_modes call. This also fixes the NULL deref problem (10085) which was introduced/revealed by commit bab87ef4 ("drm/i915: Disable hotplug detection handlers during driver init/shutdown") After the above change MST connectors will not change state during driver init/shutdown; thus some of these connectors with no I2C/DDC adapter registered for them (since the given MST port has no sink connected) may stay then in the 'unknown' connector status. The get_modes() hook should not try to use the I2C/DDC adapter in this state (which would lead to the above NULL deref) which this patch ensures. v2: - Remove the redundant check from intel_crt_ddc_get_modes(). - Rebase on latest drm-tip. - Add Fixes: line / related commit notes.

Prevent accessing the HW from the SDVO/TV get_modes connector hook. Returning 0 from the hook will make the caller - drm_helper_probe_single_connector_modes() - return a default/EDID override mode list to users. This matches the case where intel_sdvo_get_tv_modes() fails to retrieve the current mode list due to a HW access failure. v2: Clarify the commit message wrt. which modes get_modes() returns.

Commit bd077259 ("drm/i915/vdsc: Add function to read any PPS register") defines a new macro to calculate the DSC PPS register addresses with PPS number as an input. This macro correctly calculates the addresses till PPS 11 since the addresses increment by 4. So in that case the following macro works correctly to give correct register address: _MMIO(_DSCA_PPS_0 + (pps) * 4) However after PPS 11, the register address for PPS 12 increments by 12 because of RC Buffer memory allocation in between. Because of this discontinuity in the address space, the macro calculates wrong addresses for PPS 12 - 16 resulting into incorrect DSC PPS parameter value read/writes causing DSC corruption. This fixes it by correcting this macro to add the offset of 12 for PPS >=12. v3: Add correct paranthesis for pps argument (Jani Nikula) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/10172 Fixes: bd077259 ("drm/i915/vdsc: Add function to read any PPS register") Cc: Suraj Kandpal <suraj.kandpal@intel.com> Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Cc: Animesh Manna <animesh.manna@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Sean Paul <sean@poorly.run> Cc: Drew Davenport <ddavenport@chromium.org> Signed-off-by:

On MTL the GOP (for whatever reason) likes to bind its framebuffer high up in the ggtt address space. This can conflict with whatever ggtt_reserve_guc_top() is trying to do, and the result is that ggtt_reserve_guc_top() fails and then we proceed to explode when trying to tear down the driver. Thus far I haven't analyzed what causes the actual fireworks, but it's not super important as even if it didn't explode we'd still fail the driver load and the user would be left with an unusable GPU. To remedy this (without having to figure out exactly what ggtt_reserve_guc_top() is trying to achieve) we can attempt to relocate the BIOS framebuffer to a lower ggtt address. We can do this at this early point in driver init because nothing else is supposed to be clobbering the ggtt yet. So we simply change where in the ggtt we pin the vma, the original PTEs will be left as is, and the new PTEs will get written with the same dma addresses. The plane will keep on scanning out from the original PTEs until we are done with the whole process, and at that point we rewrite the plane's surface address register to point at the new ggtt address. Since we don't need a specific ggtt address for the plane (apart from needing it to land in the mappable region for normal stolen objects) we'll just try to pin it without a fixed offset first. It should end up at the lowest available address (which really should be 0 at this point in the driver init). If that fails we'll fall back to just pinning it exactly to the origianal address. To make sure we don't accidentlally pin it partially over the original ggtt range (as that would corrupt the original PTEs) we reserve the original range temporarily during this process. v2: Try to pin explicitly to ggtt offset 0 as otherwise DG2 puts it even higher (atm we have no PIN_LOW flag to force it low) v3: "fix" xe Reviewed-by:Andrzej Hajda <andrzej.hajda@intel.com> Tested-by:

Currently we assume that we bind the BIOS fb exactly into the same ggtt address where the BIOS left it. That is about to change, and in order to keep intel_reuse_initial_plane_obj() working as intended we need to compare the original ggtt offset (called 'base' here) as opposed to the actual vma ggtt offset we selected. Otherwise the first plane could change the ggtt offset, and then subsequent planes would no longer notice that they are in fact using the same ggtt offset that the first plane was already using. Thus the reuse check will fail and we proceed to turn off these subsequent planes. TODO: would probably make more sense to do the pure readout first for all the planes, then check for fb reuse, and only then proceed to pin the object into the final location in the ggtt... v2: "fix" xe Reviewed-by:

The "io" address of an object is its dma address minus the region.start. Subtract the latter to make smem_start correct. The current code happens to work for genuine LMEM objects as LMEM region.start==0, but for LMEMBAR stolen objects region.start!=0. TODO: perhaps just set smem_start=0 always as our .fb_mmap() implementation no longer depends on it? Need to double check it's not needed for anything else... Reviewed-by:
