Meteor Lake has demonstrated consistent stability for some time. All user-space API modifications tide to its core platform functions are operational. The necessary firmware components are set up and comprehensive testing has been condused over a period. Given the recent faborable CI results, as well, we believe it's time to eliminate the 'force_probe' prerequisite and activate the platform by default. Signed-off-by:

Imre Deak authored
Similarly to eDP and SST-DP connectors read out the DSC capabilities for MST connectors as well. Atm these will match the root port's DSC caps and only used after a follow-up change enables the decompression for each stream separately (vs. the current way of enabling it only globally in the first branch device downstream of the root port). Reviewed-by:

Imre Deak authored
In an MST topology the DSC capabilities are specific to each connector, retrieved either from the sink if it decompresses the stream, or from a branch device between the source and the sink in case this branch device does the decompression. Accordingly each connector needs to cache its own DSC DPCD and FEC capabilities, along with the AUX device through which the decompression can be enabled. This patch prepares for that by storing the capabilities and the DSC AUX device in the connector, for now these just matching the version stored in intel_dp. The follow-up patches will convert all users to look up these in the connector instead of intel_dp, after which the intel_dp copies are removed. v2: - Rebased on intel_edp_get_dsc_sink_cap() addition in previous patch. v3: - Rebased on read-out fix for eDP in previous patch.

Check only the eDP or the DP specific DPCD revision depending on the sink type. Pass the corresponding revision to the function, which allows getting the DSC caps of a branch device (in an MST topology, which has its own DPCD and so DPCD revision). While at it use DP_DPCD_REV_14 instead of open coding it and for clarity add a separate function to read out the DSC capability on eDP. v2: - Use DP_DPCD_REV_14 instead of open coding it. (Stan) - Check EDP_DCPD_REV/DPCD_REV in a clearer way. (Ville) v3: - Fix the read-out for eDP in intel_dp_detect().

With all the known issues sorted out we can start to use DSB to load the LUTs. Reviewed-by:

Ville Syrjälä authored
The display engine does not snoop the caches so we should mark the DSB command buffer as I915_CACHE_NONE. i915_gem_object_create_internal() always gives us I915_CACHE_LLC on LLC platforms. And to make things 100% correct we should also clflush at the end, if necessary. Note that currently this is a non-issue as we always write the command buffer through a WC mapping, so a cache flush is not actually needed. But we might actually want to consider a WB mapping since we also end up reading from the command buffer (in the indexed reg write handling). Either that or we should do something else to avoid those reads (might actually be even more sensible on DGFX since we end up reading over PCIe). But we should measure the overhead first... Anyways, no real harm in adding the belts and suspenders here so that the code will work correctly regardless of how we map the buffer. If we do get a WC mapping (as we request) i915_gem_object_flush_map() will be a nop. Well, apart form a wmb() which may just flush the WC buffer a bit earlier than would otherwise happen (at the latest the mmio accesses would trigger the WC flush). Signed-off-by:

Using system memory for the DSB command buffer doesn't appear to work. On DG2 it seems like the hardware internally replaces the actual memory reads with zeroes, and so we end up executing a bunch of NOOPs instead of whatever commands we put in the buffer. To determine that I measured the time it takes to execute the instructions, and the results are always more or less consistent with executing a buffer full of NOOPs from local memory. Another theory I considered was some kind of cache coherency issue. Looks like i915_gem_object_pin_map_unlocked() will in fact give you a WB mapping for system memory on DGFX regardless of what mapping mode was requested (WC in case of the DSB code). But clflush did not change the behaviour at all, so that theory seems moot. On DG1 it looks like the hardware might actually be fetching data from system memory as the logs indicate that we just get underruns. But that is equally bad, so doesn't look like we can really use system memory on DG1 either. Thus always allocate the DSB command buffer from local memory on discrete GPUs. Signed-off-by:

On the Lenovo Yoga Tab 3 Pro YT3-X90F there are 2 issues with the backlight on/off MIPI sequences: 1. The backlight on sequence has an I2C MIPI sequence element which uses bus 0, but there is a bogus I2cSerialBus resource under the GPU in the DSDT which causes i2c_acpi_find_adapter() to pick the wrong bus. 2. There is no backlight off sequence, causing the backlight to stay on. Add a DMI quirk fixing both issues. v2: - Add Closes tag to gitlab issue with drm.debug=0xe, VBT info Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9380Signed-off-by:

drm/i915/vlv_dsi: Add DMI quirk for wrong I2C bus and panel size on Lenovo Yoga Tablet 2 series (v3) On the Lenovo Yoga Tablet 2 830 / 1050 there are 2 problems: 1. The I2C MIPI sequence elements reference bus 3. ACPI has I2C1 - I2C7 which under Linux become bus 0 - 6. And the MIPI sequence reference to bus 3 is indented for I2C3 which is bus 2 under Linux. This leads to errors like these: [ 178.244049] i2c_designware 80860F41:03: controller timed out [ 178.245703] i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (169) There are 3 timeouts when the panel is on, delaying waking up the screen on a key press by 3 seconds. Note mipi_exec_i2c() cannot just subtract 1 from the bus given in the I2C MIPI sequence element. Since on other devices the I2C bus-numbers used in the MIPI sequences do actually start at 0. 2. width_/height_mm contain a bogus 192mm x 120mm size. This is especially a problem on the 8" 830 version which uses a 10:16 portrait screen where as the bogus size is 16:10. Add a DMI quirk to override the I2C bus and the panel size with the correct values. Note both the 10" 1050 models as well as the 8" 830 models use the same mainboard and thus the same DMI strings. The 10" 1050 uses a 1920x1200 landscape screen, where as the 8" 830 uses a 1200x1920 portrait screen, so the quirk handling uses the display resolution to detect the model. v2: - Also override i2c_bus_num to fix mipi_exec_i2c() timeouts v3: - Add Closes tag to gitlab issue with drm.debug=0xe, VBT info Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9379Reviewed-by:

Vtotal is wrong in the BIOS supplied modeline for the DSI panel on the Asus TF103C leading to the last line of the display being shown as the first line. Original: "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 820 0x8 0xa Fixed: "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 816 0x8 0xa The factory installed Android has a hardcoded modeline in its kernel, causing it to not suffer from this BIOS bug; and the Android boot-splash which uses the EFI FB which does have this bug has the last line all black causing the bug to not be visible. This commit introduces a generic DMI based quirk mechanism to vlv_dsi for doing various fixups, and uses this to correct the modeline. v2: - s/mode_fixup/dmi_quirk/ to make the new DMI quirk mechanism more generic - Add a comment with the old and new modelines to the patch and commit msg v3: - Add Closes tag to gitlab issue with drm.debug=0xe, VBT info Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9381Reviewed-by:
