Use the new link training delay helpers, fixing the delays for 128b/132b. For existing 8b/10b functionality, this will cause additional 1-byte DPCD reads for LTTPR delays instead of using the cached values. It's just too complicated to combine generic helpers with local caching in a sensible way.

Reuse the 8b/10b link training delay helpers. Functionally this skips the check for invalid values for DPCD 1.4 and later at clock recovery delay (as it's a fixed delay and bypasses the rd_interval) but the same value will be checked and invalid values reported at channel equalization.

The link training delays are different and/or available in different DPCD offsets depending on: - Clock recovery vs. channel equalization - DPRX vs. LTTPR - 128b/132b vs. 8b/10b - DPCD 1.4+ vs. earlier Add helpers to get the correct delays in us, reading DPCD if necessary. This is more straightforward than trying to retrofit the existing helpers to take 128b/132b into account. Having to pass in the DPCD receiver cap field seems unavoidable, because reading it involves checking the revision and reading extended receiver cap. So unfortunately the interface is mixed cached and read as needed. v2: Remove delay_us < 0 check and the whole local var (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211014150059.28957-1-jani.nikula@intel.com

Let's add lpt_pch_disable() as the counterpart to lpt_pch_enable(). Note that unlike the ilk+ code the fdi_link_train() and fdi_disable() calls are still left directly in intel_crt.c. If we wanted to move those we'd need to add lpt_pch_pre_enable(). But the two fdi direct fdi calls are pretry symmetric so it doesn't seem too bad to just keep them as is. v2: Make lpt_disable_pch_transcoder() static (lkp@intel.com) Cc: Dave Airlie <airlied@redhat.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211015071625.593-10-ville.syrjala@linux.intel.comReviewed-by: Dave Airlie <airlied@redhat.com>

Reanme intel_ddi_fdi_post_disable() to hsw_fdi_disable() and relocate it next to all the other code dealing with FDI_RX. intel_ddi.c has now been cleansed of FDI_RX. In order to avoid exposing intel_disable_ddi_buf() outside intel_ddi.c we can just open code the DDI_BUF_CTL write. The enable side already has all that stuff open coded so this actually is more symmetric. But we do need to remeber to bring the intel_wait_ddi_buf_idle() call over from inside intel_disable_ddi_buf().

Move the lpt_get_iclkip() call from hsw_crt_get_config() since that's where we have the lpt_program_iclkip() call as well. Tehcnically this isn't perhaps quite right since iCLKIP is providing the CRT dotclock. So one can argue all of it should be directly in intel_crt.c. But since the CRT port is the only one on the PCH sticking it all into the PCH code seems OK.

Note that the nuked TRANS_DDI_FUNC_CTL readout from hsw_get_ddi_port_state() is now etirely redundant since we get called from the encoder->get_config() so we already know we're dealing with the correct DDI port.

There's lots of expensive stuff inserted between the PLANE_CTL and PLANE_SURF writes even though the comment before the PLANE_CTL write says not to put stuff there. Move it all to a more apporiate place. There's also a weird PLANE_COLOR_CTL RMW in there. I guess because force_black was computed way too late originally, but that is now sorted.

No real reason to have this pxp state computation in intel_atomic_check_planes(). Just stuff it into skl_plane_check(). There was also some funny state copying being done from the old plane state to the new plane state when the plane is anyway disabled. The one thing we presumably must remember to do is copy over the decrypt state when assigning a Y plane for planar YCbCr scanout, so that the Y plane's PLANE_SURF will get the appropriate bit set. The force_black thing should not matter as I'm pretty sure all that stuff is ignored for the Y plane. I suppose this was the reason for the odd placement for the state computation, but I see no reason to deviate from the standard way of doing these things. This also guarantees that we don't calculate things differently between the linked UV and Y plane. v2: Only do stuff for icl+ since 'force_black' depends on the plane CSC which is an icl+ feature Cc: Anshuman Gupta <anshuman.gupta@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Juston Li <juston.li@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211006235704.28894-2-ville.syrjala@linux.intel.com Reviewed-by: Juston Li <juston.li@intel.com> #v1

A new warning in clang points out a place in this file where a bitwise OR is being used with boolean types: drivers/gpu/drm/i915/intel_pm.c:3066:12: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] changed = ilk_increase_wm_latency(dev_priv, dev_priv->wm.pri_latency, 12) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This construct is intentional, as it allows every one of the calls to ilk_increase_wm_latency() to occur (instead of short circuiting with logical OR) while still caring about the result of each call. To make this clearer to the compiler, use the '|=' operator to assign the result of each ilk_increase_wm_latency() call to changed, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.

The I915_TILING_* values in our uapi header are intended solely for use with the old get_tiling/set_tiling ioctls that operate on hardware de-tiling fences; all other uapi communication about tiling types is done via framebuffer modifiers rather than with these old values. On newer Intel platforms detiling fences no longer exist so the old get_tiling/set_tiling ioctls are no longer usable and will always return -EOPNOTSUPP. This means there's no reason to add new tiling types (such as the Tile4 format introduced by Xe_HP) to the uapi header here. Any kernel-internal code that needs to represent tiling format should either rely on framebuffer modifiers (as the display code does) or use some kind of non-uapi enum (as the GEM blt selftest now does).
