HMM provides new APIs and helps in kernel 5.2-rc1 to simplify driver path. The old hmm APIs are deprecated and will be removed in future. Below are changes in driver: 1. Change hmm_vma_fault to hmm_range_register and hmm_range_fault which supports range with multiple vmas, remove the multiple vmas handle path and data structure. 2. Change hmm_vma_range_done to hmm_range_unregister. 3. Use default flags to avoid pre-fill pfn arrays. 4. Use new hmm_device_ helpers. Signed-off-by:

The "block" variable can be set by the user through debugfs, so it can be quite large which leads to shift wrapping here. This means we report a "block" as supported when it's not, and that leads to array overflows later on. This bug is not really a security issue in real life, because debugfs is generally root only.

[Why] Found issue in EDID Emulation where if we connect a display using a passive HDMI-DP dongle, disconnect it and then try to emulate a display using DP, we could not see 4K modes. This was because on a disconnect, dongle_max_pix_clk was still set so when we emulate using DP, in dc_link_validate_mode_timing(), it would think we were still using a dongle and limit the modes we support. [How] In dc_link_detect(), set dongle_max_pix_clk to 0 when we detect a hotplug out ( if new_connection_type = dc_connection_none ). Signed-off-by:

[Why] Our existing logic in deciding whether to use RAM or ROM depends on whether we are dealing with an identity gamma ramp. [How] In addition to the is_identity flag a new is_logical_identity flag has been added. The is_identity flag now denotes whether the OS gamma is an RGB256 identity and the new logical identity will inidicate that the given gamma ramp regardless of its type is identity. Signed-off-by:

[Why] HPD not going to be high if Panel VDD is off And all AUX transaction will fail :( [How] 1. Power on VDD before attempting detection if it isn't already on 2. Improve the robustness by having a retry mechanism on the first DPCD read after VDD on. If a particular board always holds HPD high incorrectly, the AUX access may fail, so we can retry in those scenarios. This change would only improve logic since it prevents AUX failure leading to bad resolution on internal panel. 3. We should never need to re-detect internal panel, so logic is re-arranged a bit to skip earlier. Signed-off-by:

[Why] To prepare for the upcoming DRM plane color management properties we need to correct a lot of wrong behavior and assumptions made for CRTC color management. The documentation added by this commit in amdgpu_dm_color explains how the HW color pipeline works and its limitations with the DRM interface. The current implementation does the following wrong: - Implicit sRGB DGM when no CRTC DGM is set - Implicit sRGB RGM when no CRTC RGM is set - No way to specify a non-linear DGM matrix that produces correct output - No way to specify a correct RGM when a linear DGM is used We had workarounds for passing kms_color tests but not all of the behavior we had wrong was covered by these tests (especially when it comes to non-linear DGM). Testing both DGM and RGM at the same time isn't something kms_color tests well either. [How] The specifics for how color management works in AMDGPU and the new behavior can be found by reading the documentation added to amdgpu_dm_color.c from this patch. All of the incorrect cases from the old implementation have been addressed for the atomic interface, but there still a few TODOs for the legacy one. Note: this does cause regressions for kms_color@pipe-a-ctm-* over HDMI. The result looks correct from visual inspection but the CRC no longer matches. For reference, the test was previously doing the following: linear degamma -> CTM -> sRGB regamma -> RGB to YUV (709) -> ... Now the test is doing: linear degamma -> CTM -> linear regamma -> RGB to YUV (709) -> ... Signed-off-by:

[Why] Almost every function in DC that works with stream state expects that the current state on the stream is the one that it should be writing out. These functions are typically triggered by specifying a particular stream update - but the actual contents of the stream update itself are ignored, leaving it to the DM to actually update the stream state itself. The problem with doing this in DM is a matter of timing. On Linux most of this is incorrectly done in atomic check, when we actually want it to be done during atomic commit tail while access to DC is locked. To give an example, a commit requesting to modify color management state for DM could come in, be rejected, but still have modified the actual system state for the stream since it's shared memory. The next time color management gets programmed it'll use the rejected color management info - which might not even still be around if it's a custom transfer function. So a reasonable place to perform this is within DC itself and this is the model that's currently in use for surface updates. DC can even compare the current system state to the incoming surface update to determine update level, something that can't currnetly be done with the framework for stream updates. [How] Duplicate the framework used for surface updates for stream updates as well. Copy all the updates after checking the update type. Signed-off-by:

[WHY] Some panels return a link rate of 0 (unknown) in DPCD 0. In this case, an appropriate mode cannot be set, and certain panels will show corruption as they are forced to use a mode they do not support. [HOW] Read DPCD 10 in the case where supported link rate from DPCD 0 is unknown, and pass that value on to the reported link rate. This re-introduces behaviour present in previous versions that appears to have been accidentally removed. Signed-off-by:

[Why] The module parameter to specify the default ABM level is now defined, so hook it up in DM. [How] On connector reset specify the default level. DC will program this as part of the modeset since it gets passed onto the stream in dm_update_crtc_state. It's only set for eDP connectors, but it doesn't matter if this is specified for connectors or hardware that doesn't support ABM. It's DC's responsibility to check that ABM can be set or adjusted, and DC does check that the DMCU firmware is running and if there's backlight control available. Signed-off-by:

[Why] It's non trivial to configure or specify an ABM reduction level for userspace outside of X. There is also no method to specify the default ABM value at boot time. A parameter should be added to configure this. [How] Expose a module parameter that can specify the default ABM level to use for eDP connectors on DC enabled hardware that loads the DMCU firmware. The default is still disabled (0), but levels can range from 1-4. Levels control how much the backlight can be reduced, with being the least amount of reduction and four being the most reduction.

[Why] Whenever the a modeset is allowed (but not neccessarily required) we currently recreate all the planes in the state. Most IGT tests and legacy IOCTLs create atomic commits with this flag set, so the pipes are often unnecessarily reprogrammed. Poor performance and stuttering can occur when many of these commits are frequently issued. This flag was needed when the appropriate conditions for checking whether the planes needed a reset were not in place, but should_reset_plane should cover everything needed now. [How] Drop the check for state->allow_modeset in should_reset_plane. All planes on a CRTC should reset in the following conditions: - The CRTC needs a modeset - The CRTC degamma changes - Planes are added or removed to the CRTC These conditions are all covered in should_reset_plane. We still can't drop the format change check in should_reset_plane since fill_dc_plane_info_and_addr isn't called when validating the state, so we can't tell if a FULL update is needed or not.

[Why] The old logic for checking which output depth to use relied on using the current connector state rather than the new proposed state. This was a problem when performing atomic commits since we weren't verifying it against the incoming max_requested_bpc. But switching this to only use the new state and not the current state breaks filtering modes - it'll always assume that the maximum bpc supported by the display is in use, which will cause certain modes like 1440p@144Hz to be filtered even when using 8bpc. [How] Still use the connector->state if we aren't passed an explicit state. This will respect the max_bpc the user currently has when filtering modes. Also remember to reset the default max_requested_bpc to 8 whenever connector reset is called to retain old behavior when using the new property.

[Why] Unlike our regular connectors, MST connectors don't start off with an initial connector state. This causes a NULL pointer dereference to occur when attaching the bpc property since it tries to modify the connector state. We need an initial connector state on the connector to avoid the crash.
