git://anongit.freedesktop.org/drm/drm-intel into drm-next UAPI Changes: - drm/i915: Show per-engine default property values in sysfs By providing the default values configured into the kernel via sysfs, it is much more convenient for userspace to restore those sane defaults, or at least know what are considered good baseline. This is useful, for example, to cleanup after any failed userspace prior to commencing new jobs.

2020-04-07drm/dp_mst: Remove drm_dp_mst_has_audio()Lyude Paul1-2/+1
Drive-by fix I noticed the other day - drm_dp_mst_has_audio() only ever made sense back when we still had to validate ports before accessing them in order to (attempt to) avoid NULL dereferences. Since we have proper reference counting that guarantees we always can safely access the MST port, there's no use in keeping this function around as all it does is validate the port pointer before checking the audio status. Note - drm_dp_mst_port->has_audio is technically protected by drm_device->mode_config.connection_mutex, since it's only ever updated from drm_dp_mst_get_edid(). Additionally, we change the declaration for port in struct intel_connector to be properly typed, so we can directly access it.

We're going to want access to the atomic state for iterating the slave crtcs when enabling the port sync master crtc. Pass the atomic state all the way down. The alternative would be yet another encoder hook which we'll have to call after all the normal modeset stuff is done. Not really a fan of yet another hook just for this. Note that during readout state sanitation we are now going to pass NULL as the atomic state since we don't have one. We need to change that and then we can also s/crtc_state/crtc/ and s/conn_state/conn/ for the encoder hooks as well.

Use the recently introduced encoder .compute_config_late() hook to do the MST master transcoder assignment. Avoids having to do it in a funny way before we know the CPU transcoder of each pipe. And now we can also properly use hw.active instead of uapi.active since it too has been calculated earlier for everyone.

2020-03-03drm/dp: Introduce EDID-based quirksLyude Paul1-1/+1
The whole point of using OUIs is so that we can recognize certain devices and potentially apply quirks for them. Normally this should work quite well, but there appears to be quite a number of laptop panels out there that will fill the OUI but not the device ID. As such, for devices like this I can't imagine it's a very good idea to try relying on OUIs for applying quirks. As well, some laptop vendors have confirmed to us that their panels have this exact issue. So, let's introduce the ability to apply DP quirks based on EDID identification. We reuse the same quirk bits for OUI-based quirks, so that callers can simply check all possible quirks using drm_dp_has_quirk().

2019-12-23drm/i915/tgl: Select master transcoder for MST streamJosé Roberto de Souza1-9/+134
On TGL the blending of all the streams have moved from DDI to transcoder, so now every transcoder working over the same MST port must send its stream to a master transcoder and master will send to DDI respecting the time slots. So here adding all the CRTCs that shares the same MST stream if needed and computing their state again, it will pick the lowest pipe/transcoder among the ones in the same stream to be master. Most of the time skl_commit_modeset_enables() enables pipes in a crescent order but due DDB overlapping it might not happen, this scenarios will be handled in the next patch. v2: - Using recently added intel_crtc_state_reset() to set mst_master_transcoder to invalid transcoder for all non gen12 & MST code paths - Setting lowest pipe/transcoder as master, previously it was the first one but setting a predictable one will help in future MST e port sync integration - Moving to intel type as much as we can v3: - Now intel_dp_mst_master_trans_compute() returns the MST master transcoder - Replaced stdbool.h by linux/types.h - Skip the connector being checked in intel_dp_mst_atomic_master_trans_check() - Using pipe instead of transcoder to compute MST master v4: - renamed connector_state to conn_state v5: - Improved the parameters of intel_dp_mst_master_trans_compute() to simply code - Added call drm_atomic_add_affected_planes() in intel_dp_mst_atomic_master_trans_check() as helper could not do it for us - Removed "if (ret)" left over from v3 changes v6: - handled ret == I915_MAX_PIPES case in compute BSpec: 50493 BSpec: 49190 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191223010654.67037-2-jose.souza@intel.com
2019-12-18drm/i915: Move stuff from haswell_crtc_disable() into encoder .post_disable()Ville Syrjälä1-0/+11
Move all of haswell_crtc_disable() into the encoder .post_disable() hooks. Now we're left with just calling the .disable() and .post_disable() hooks back to back. I chose to move the code into the .post_disable() hook instead of the .disable() hook as most of the sequence is currently implemented in the .post_disable() hook. We should collapse it all down to just one hook and then the encoders can drive the modeset sequence fully. But that may need some further refactoring as we currently call the ddi .post_disable() hook from mst code and we can't just replace that with a call to the ddi .disable() hook. Should also follow up with similar treatment for the enable sequence but let's start here where it's easier.

And since we don't even disable the PLL in between let's just move everything into .post_disable(). intel_dp_mst does forward the .post_disable() call to intel_ddi at the very end of its own .post_disable() hook, so this time MST I shouldn't even break MST by accident.

2019-11-13drm/i915: Split a setting of MSA to MST and SSTGwan-gyeong Mun1-0/+2
The setting of MSA is done by the DDI .pre_enable() hook. And when we are using MST, the MSA is only set to first mst stream by calling of DDI .pre_eanble() hook. It raies issues to non-first mst streams. Wrong MSA or missed MSA packets might show scrambled screen or wrong screen. This splits a setting of MSA to MST and SST cases. And In the MST case it will call a setting of MSA after an allocating of Virtual Channel from MST encoder pre_enable callback.

Compute changes: https://github.com/intel/compute-runtime/pull/228 The compute driver is shipping in Ubuntu. uAPI acked by Mesa folks. - Put future HW and their uAPIs under STAGING & BROKEN Introduces DRM_I915_UNSTABLE Kconfig menu for working on the new uAPI for future HW in upstream. We already disable driver loading by default the platform is deemed ready. This is a second level of protection based on compile time switch (STAGING & BROKEN). - Under DRM_I915_UNSTABLE: Add the fake lmem region on iGFX Fake local memory region on integrated GPU through cmdline: memmap=2G$16G i915.fake_lmem_start=0x400000000 Currently allows testing non-mappable GGTT behavior and running kernel selftest for local memory.

2019-11-01drm/i915: Handle a few more cases for crtc hw/uapi split, v3.Maarten Lankhorst1-4/+8
We are still looking at drm_crtc_state in a few places, convert those to use intel_crtc_state instead. Changes since v1: - Move to before uapi/hw split. - Add hunks for intel_pm.c as well. Changes since v2: - Incorporate Ville's feedback.

2019-10-31drm/i915/mst: Document the userspace fail with possible_crtcsVille Syrjälä1-0/+8
To avoid accidentally breaking things in the future add a comment explaining why we misconfigure the pipe_mask. Also toss in a TODO for investigating a single encoder approach as opposed to the encoder-per-pipe approach. v2: Drop a bogus TODO comment Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191002162505.30716-6-ville.syrjala@linux.intel.com Reviewed-by: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com>
2019-10-31drm/i915: Simplify pipe_mask setup even furtherVille Syrjälä1-4/+1
Just set pipe_mask=~0 for the non-special cases where any pipe will do. intel_encoder_possible_crtcs() will anyway drop out anything that doesn't exist.
