[Why] In dm resume, we firstly restore dc state and do the mst resume for topology probing thereafter. If we change dpcd DP_MSTM_CTRL value after LT in mst reume, it will cause light up problem on the hub. [How] Revert commit 202dc359 ("drm/amd/display: Defer handling mst up request in resume").

If a queue is already assigned to the hardware, then a newly submitted job can start straight away without waiting for the tick. However in this case the devfreq infrastructure isn't notified that the GPU is busy. By the time the tick happens the job might well have finished and no time will be accounted for the GPU being busy. Fix this by recording the GPU as busy directly in queue_run_job() in the case where there is a CSG assigned and therefore we just ring the doorbell.

Add helpers to convert between q4 fixed point and integer/fraction values. Also add the format/argument macros required to printk q4 fixed point variables. The q4 notation is based on the short variant described by https://en.wikipedia.org/wiki/Q_(number_format) where only the number of fraction bits in the fixed point value are defined, while the full size is deducted from the container type, that is the size of int for these helpers. Using the fxp_ prefix, which makes moving these helpers outside of drm to a more generic place easier, if they prove to be useful. These are needed by later patches dumping the Display Stream Compression configuration in DRM core and in the i915 driver to replace the corresponding bpp_x16 helpers defined locally in the driver. v2: Use the more generic/descriptive fxp_q4 prefix instead of drm_x16.

Panfrost DRM driver uses devfreq to perform DVFS, while using simple_ondemand devfreq governor by default. This causes driver initialization to fail on boot when simple_ondemand governor isn't built into the kernel statically, as a result of the missing module dependency and, consequently, the required governor module not being included in the initial ramdisk. Thus, let's mark simple_ondemand governor as a softdep for Panfrost, to have its kernel module included in the initial ramdisk. This is a rather longstanding issue that has forced distributions to build devfreq governors statically into their kernels, [1][2] or has forced users to introduce some unnecessary workarounds. [3] For future reference, not having support for the simple_ondemand governor in the initial ramdisk produces errors in the kernel log similar to these below, which were taken from a Pine64 RockPro64: panfrost ff9a0000.gpu: [drm:panfrost_devfreq_init [panfrost]] *ERROR* Couldn't initialize GPU devfreq panfrost ff9a0000.gpu: Fatal error during GPU init panfrost: probe of ff9a0000.gpu failed with error -22 Having simple_ondemand marked as a softdep for Panfrost may not resolve this issue for all Linux distributions. In particular, it will remain unresolved for the distributions whose utilities for the initial ramdisk generation do not handle the available softdep information [4] properly yet. However, some Linux distributions already handle softdeps properly while generating their initial ramdisks, [5] and this is a prerequisite step in the right direction for the distributions that don't handle them properly yet.

The function ast_crtc_dpms() is left over from when the ast driver did not implement atomic modesetting. But DPMS is not supported by atomic modesetting and the helper is only called to enable or disable the CRTC sync pulses. Inline the function into its callers. To disable the CRTC, ast sets (AST_DPMS_VSYNC_OFF | AST_DPMS_HSYNC_OFF) in VGACRB6. Replace the constants with the correct register constants for VGACRB6. Signed-off-by:

The SCREEN_DISABLE bit controls scanout from display memory. The bit affects all planes, so set it only in the CRTC's atomic enable and disable functions. A number of bugs affect this fix. First of all, ast_set_std_regs() tries to set VGASR1 except for the SD bit. But the read bitmask is invert, so it preserves anything except the SD bit. Fix this by re-inverting the read mask. The second issue is that primary-plane and CRTC helpers modify the SD bit. The bit controls scanout for all planes, primary and HW cursor, so set it only in the CRTC code. Further add a constant to represent the SD bit in VGASR1. Keep the plane's atomic_disable around to make the DRM framework happy. v2: - fix typos in commit message Signed-off-by:

Thomas Zimmermann authored
Several color registers are programmed in the DPMS code of the CRTC's atomic_enable helper and the primary plane's atomic_update. It requires the color format and the display mode. Both code paths handle different cases: the DPMS's code will not be executed if the color format changes without a full mode switch. The plane's code only runs if the color format changes, but ignores display-mode changes. The color format is a property of the primary plane, so consolidate all color-format code in the plane's atomic_update. Remove it from the DPMS helper. v2: - clarify commit message (Jocelyn) Signed-off-by:

Thomas Zimmermann authored
Do all mode setting in ast_crtc_helper_mode_set_nofb(), which always runs after disabling the CRTC and before programming the planes. Removes implicit synchronization between the CRTC's atomic disable, enable and the vertical retrace. Display-mode updates require HW cursors to be disabled. The HW cursor only picks up changes at vertical retrace periods. So the CRTC's atomic_disable helper waited for the retrace to delay any following mode-setting operations, which then happened in atomic_enable. See [1] for a description of the problem. With the CRTC helper callback mode_set_nofb, we can now synchronize and reprogram in the same place. As it always runs before the plane update, the plane code can be reordered with the CRTC's later atomic_enable et al. Signed-off-by:
