Let's make sure FBC is always disabled when we start to take over the hardware state. I suspect this should never really happen, since the only time when we really should be taking over with the display already active is when the previous state was progammed by the BIOS, which likely shouldn't use FBC. This could be driver init, or S4 resume when the boot kernel doesn't load i915. But I suppose no harm in keeping this code around for exra safety since it's quite trivial. Signed-off-by:

By the time intel_fbc_global_disable() gets called during driver teardown we should have already disabled all the crtcs, so no way FBC should be enabled at this point. And I have no idea what the other user (i915_restore_display()) is even trying to achieve. So let's just throw intel_fbc_global_disable() into the bin. Signed-off-by:

Don't issue a nuke from frontbuffer flush while a flip is pending. This avoids the DSPADDR/DSPSURF rmw abuse from the pre-snb nuke from racing with the DSPADDR/DSPSURF write being performed by the flip/plane update. The flip itself will already cause the nuke so a double nuke is redundant. Signed-off-by:

Not sure what the point of this fbc->possible_frontbuffer_bits is. And especially don't see why it's returning all the bits when fbc is not even enabled. So let's just get rid of this and only say we are interested in the plane's frontbuffer bits when fbc is actually enabled. Signed-off-by:

With some VRR panels, user can turn VRR ON/OFF on the fly from the panel settings. When VRR is turned OFF ,sends a long HPD to the driver clearing the Ignore MSA bit in the DPCD. Currently the driver parses that onevery HPD but fails to reset the corresponding VRR Capable Connector property. Hence the userspace still sees this as VRR Capable panel which is incorrect. Fix this by explicitly resetting the connector property. v2: Reset vrr capable if status == connector_disconnected v3: Use i915 and use bool vrr_capable (Jani Nikula) v4: Move vrr_capable to after update modes call (Jani N) Remove the redundant comment (Jan N) v5: Fixes the regression on older platforms by resetting the VRR only if HAS_VRR v6: Remove the checks from driver, add in drm core before setting VRR prop (Ville) v7: Move VRR set/reset to set/unset_edid (Ville) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Fixes: 9bc34b4d ("drm/i915/display/vrr: Reset VRR capable property on a long hpd") Signed-off-by:

The render/media engines on DG2 unify render compression and media compression into a single format for the first time, using the Tile 4 layout for main surfaces. The compression algorithm is different from any previous platform and the display engine must still be configured to decompress either a render or media compressed surface; as such, we need new RC and MC framebuffer modifiers to represent buffers in this format. v2: Clarify modifier layout description.

In addition to the fp_timing,dvo_timing,panel_pnp_id tables there also exists a panel_name table. Unlike the others this is just one offset+table_size even though there are still 16 actual panel_names in the data block. The panel_name table made its first appearance somewhere around VBT version 156-163. The exact version is not known. But we don't need to know that since we can just check whether the pointers block has enough room for it or not. Signed-off-by:

Currently get_lvds_fp_timing() still returns a pointer to the original data block rather than our copy. Let's convert the data pointer offsets to be relative to the data block rather than the whole BDB. With that we can make get_lvds_fp_timing() return a pointer to the copy. Signed-off-by:

Make a copy of each VBT data block with a guaranteed minimum size. The extra (if any) will just be left zeroed. This means we don't have to worry about going out of bounds when accessing any of the structure members. Otherwise that could easliy happen if we simply get the version check wrong, or if the VBT is broken/malicious. v2: Don't do arithmetic between bdb header and copy of the LFP data block (Jani) v3: Make all the copies up front v4: Only WARN about min_size==0 if we found the block Signed-off-by: -

We have the BDB version cached, use it. We're going to have to start doing some of the BDB block parsing later, at which point we may no longer have the VBT around anymore (we free it at the end of intel_bios_init() when it didn't come via OpRegion). Signed-off-by:

Failing the PHY calibration could be left as a warning or error, like it was before commit b4eb76d8 ("drm/i915/dg2: Skip output init on PHY calibration failure"). However that often fails for outputs not being used, which would make the warning/error appear on systems that have no visible issues. Anyway, there is still a need to fix those failures, but that is left for later. Signed-off-by:

If ret isn't zero, it is almost for sure ETIMEDOUT, because we use it in wait_for macro which does continuous retries until timeout is reached. If we still ran out of time and retries, we most likely would be interested in getting status, to understand what was the actual error propagated from PCode, rather than to find out that we had a time out, which is anyway quite obvious, if the function fails. v2: Make it status ? status : ret(thanks Vinod for the hint) Signed-off-by:

Currently skl_pcode_try_request function doesn't properly handle return value it gets from snb_pcode_rw, but treats status != 0 as success, returning true, which basically doesn't allow to use retry/timeout mechanisms if PCode happens to be busy and returns EGAIN or some other status code not equal to 0. We saw this on real hw and also tried simulating this by always returning -EAGAIN from snb_pcode_rw for 6 times, which currently will just result in false success, while it should have tried until timeout is reached: [ 22.357729] i915 0000:00:02.0: [drm:intel_cdclk_dump_config [i915]] Changing CDCLK to 307200 kHz, VCO 614400 kHz, ref 38400 kHz, bypass 19200 kHz, voltage level 0 [ 22.357831] i915 0000:00:02.0: [drm:__snb_pcode_rw [i915]] Returning EAGAIN retry 1 [ 22.357892] i915 0000:00:02.0: [drm:skl_pcode_request [i915]] Success, exiting [ 22.357936] i915 0000:00:02.0: [drm] ERROR Failed to inform PCU about cdclk change (err -11, freq 307200) We see en error because higher level api, still notices that status was wrong, however we still did try only once.
