This reverts commit 06b89b38. This fix is not proper. allocate_mqd can't be moved before allocate_sdma_queue as it depends on q->properties->sdma_id set in later. Signed-off-by:

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] 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:
