2025-02-06drm/i915: Use per-plane VT-d guard numbersVille Syrjälä
Bspec lists different VT-d guard numbers (the number of dummy padding PTEs) for different platforms and plane types. Use those instead of just assuming the max glk+ number for everything. This could avoid a bit of overhead on older platforms due to reduced padding, and it makes it easier to cross check with the spec. Note that VLV/CHV do not document this w/a at all, so not sure if it's actually needed or not. Nor do we actually know how much padding is required if it is needed. For now use the same 128 PTEs that we use for snb-bdw primary planes.

2025-02-06drm/i915: Calculate the VT-d guard size in the display codeVille Syrjälä
Currently i915_gem_object_pin_to_display_plane() uses i915_gem_object_get_tile_row_size() to calculate the tile row size for the VT-d guard w/a. That's not really proper since i915_gem_object_get_tile_row_size() only works for fenced BOs, nor does it take rotation into account. Remedy the situation by calculating the VT-d guard size in the display code where we have more information readily available. Although the default guard size (168 PTEs now) should cover the more typical fb size use cases anyway, and only very large Y/Yf-tiled framebuffers might have tile row size that exceeds it.

2025-02-05drm/i915/dmc_wl: Do not check for DMC payloadGustavo Sousa
Enabling and disabling of DMC wakelock is already coupled with enabling and disabling of dynamic DC states, which already depend on the DMC being properly loaded. As such, we do not need to check if we already have a DMC payload parsed in __intel_dmc_wl_supported(). Furthermore, the presence of such a check causes inconsistencies in the refcount if the following sequence of events happen: 1. A call to one of the register accessors from intel_de.h is done before the DMC payload is parsed. That causes intel_dmc_wl_get() to be called. Suppose the register offset qualifies as needing the wakelock. In normal circumstances, the refcount would be incremented, but, because __intel_dmc_wl_supported() returns false, the refcount is untouched. 2. In a separate worker thread, the DMC firmware is parsed. Parsing of the DMC payload is finished before the corresponding intel_dmc_wl_put() from (1) is called. 3. When in the context of (1), intel_dmc_wl_put() gets called, now we have __intel_dmc_wl_supported() returning true and we hit the warning, because the code doesn't expect a zero refcount. Let's remove that check, since it is unnecessary and causes the inconsistency illustrated above.

2025-02-03drm/i915/dp: Move max DSC BPP reduction one level higherJani Nikula
Now that {icl,xelpd}_dsc_compute_link_config() take .4 fixed point as parameter, move the common max DSC BPP reduction one level higher. Use intel_dp_dsc_bpp_step() to compute the step, and pass on to both platform specific functions. (Though it's unused for now in icl_dsc_compute_link_config()). We can drop the pipe_bpp and connector parameters.

2025-02-03drm/i915/dp: Pass .4 BPP values to {icl,xelpd}_dsc_compute_link_config()Jani Nikula
Try to keep the variables in the same domain a bit longer to reduce juggling between integers and .4 fixed point. Change parameter order to min, max while at it. For now, keep the juggling in dsc_compute_compressed_bpp() ensure min/max will always have 0 fractional part. To be fixed later.

2025-02-03drm/i915/dp: Rename some variables in xelpd_dsc_compute_link_config()Jani Nikula
Use the _x16 suffix for all .4 fixed point variables. Drop compressed_ prefix, as it's implied from the precision suffix. As dsc_min_bpp and dsc_max_bpp change domain from int to .4 in the middle of the function, they remain the same for now.

2025-02-03drm/i915/dp: Iterate DSC BPP from high to low on all platformsJani Nikula
Commit 1c56e9a39833 ("drm/i915/dp: Get optimal link config to have best compressed bpp") tries to find the best compressed bpp for the link. However, it iterates from max to min bpp on display 13+, and from min to max on other platforms. This presumably leads to minimum compressed bpp always being chosen on display 11-12. Iterate from high to low on all platforms to actually use the best possible compressed bpp. Fixes: 1c56e9a39833 ("drm/i915/dp: Get optimal link config to have best compressed bpp") Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: <stable@vger.kernel.org> # v6.7+ Reviewed-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/3bba67923cbcd13a59d26ef5fa4bb042b13c8a9b.1738327620.git.jani.nikula@intel.com
