Currently if stream->signal is neither SIGNAL_TYPE_DISPLAY_PORT_MST or SIGNAL_TYPE_DISPLAY_PORT then variable ret is uninitialized and this is checked for > 0 at the end of the function. Ret should be initialized, I believe setting it to zero is a correct default.

2021-02-25drm/panel: kd35t133: allow using non-continuous dsi clockHeiko Stuebner
The panel is able to work when dsi clock is non-continuous, thus the system power consumption can be reduced using such feature. Add MIPI_DSI_CLOCK_NON_CONTINUOUS to panel's mode_flags. Also the flag actually becomes necessary after commit c6d94e37bdbb ("drm/bridge/synopsys: dsi: add support for non-continuous HS clock") and without it the panel only emits stripes instead of output.

2021-02-25drm/rockchip: Require the YTR modifier for AFBCAlyssa Rosenzweig
The AFBC decoder used in the Rockchip VOP assumes the use of the YUV-like colourspace transform (YTR). YTR is lossless for RGB(A) buffers, which covers the RGBA8 and RGB565 formats supported in vop_convert_afbc_format. Use of YTR is signaled with the AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As such, a producer would have to generate buffers that do not use YTR, which the VOP would erroneously decode as YTR, leading to severe visual corruption. The upstream AFBC support was developed against a captured frame, which failed to exercise modifier support. Prior to bring-up of AFBC in Mesa (in the Panfrost driver), no open userspace respected modifier reporting. As such, this change is not expected to affect broken userspaces. Tested on RK3399 with Panfrost and Weston.

2021-02-24drm/drm_vblank: set the dma-fence timestamp during send_vblank_eventVeera Sundaram Sankaran
The explicit out-fences in crtc are signaled as part of vblank event, indicating all framebuffers present on the Atomic Commit request are scanned out on the screen. Though the fence signal and the vblank event notification happens at the same time, triggered by the same hardware vsync event, the timestamp set in both are different. With drivers supporting precise vblank timestamp the difference between the two timestamps would be even higher. This might have an impact on use-mode frameworks using these fence timestamps for purposes other than simple buffer usage. For instance, the Android framework [1] uses the retire-fences as an alternative to vblank when frame-updates are in progress. Set the fence timestamp during send vblank event using a new drm_send_event_timestamp_locked variant to avoid discrepancies. [1] https://android.googlesource.com/platform/frameworks/native/+/master/ services/surfaceflinger/Scheduler/Scheduler.cpp#397 Changes in v2: - Use drm_send_event_timestamp_locked to update fence timestamp - add more information to commit text Changes in v3: - use same backend helper function for variants of drm_send_event to avoid code duplications Changes in v4: - remove WARN_ON from drm_send_event_timestamp_locked Signed-off-by: Veera Sundaram Sankaran <veeras@codeaurora.org> Reviewed-by: John Stultz <john.stultz@linaro.org> Signed-off-by: Sumit Semwal <sumit.semwal@linaro.org> [sumits: minor parenthesis alignment correction] Link: https://patchwork.freedesktop.org/patch/msgid/1610757107-11892-2-git-send-email-veeras@codeaurora.org (cherry picked from commit a78e7a51d2fa9d2f482b462be4299784c884d988) Signed-off-by: Sumit Semwal <sumit.semwal@linaro.org>

2021-02-23drm/i915: Nuke INTEL_OUTPUT_FORMAT_INVALIDVille Syrjälä
We tend to use output_format!=RGB as a shorthand for YCbCr, but this fails if we have a disabled crtc where output_format==INVALID. We're now getting some fail from intel_color_check() when we have: hw.enable==false hw.ctm!=NULL output_format==INVALID Let's avoid that by throwing INTEL_OUTPUT_FORMAT_INVALID to the dumpster, and thus everything defaults to RGB when the crtc is disabled. This does beg the deeper question of how much of the state should we in fact be validating when hw/uapi.enable==false. And should we even be doing the uapi->hw copy when uapi.enable==false? So far I've not been able to come up with satisfactory answers for myself, so I'm putting it off for the moment.

2021-02-23drm/i915: Enable -WuninitializedNathan Chancellor
-Wunintialized was disabled in commit c5627461490e ("drm/i915: Disable -Wuninitialized") because there were two warnings that were false positives. The first was due to DECLARE_WAIT_QUEUE_HEAD_ONSTACK, which was fixed in LLVM 9.0.0. The second was in busywait_stop, which was fixed in LLVM 10.0.0 (issue 415). The kernel's minimum version for LLVM is 10.0.1 so this warning can be safely enabled, where it has already caught a couple bugs.

2021-02-22drm/amd/display: Add vupdate_no_lock interrupts for DCN2.1Rodrigo Siqueira
When run igt@kms_vrr in a device that uses DCN2.1 architecture, we noticed multiple failures. Furthermore, when we tested a VRR demo, we noticed a system hang where the mouse pointer still works, but the entire system freezes; in this case, we don't see any dmesg warning or failure messages kernel. This happens due to a lack of vupdate_no_lock interrupt, making the userspace wait eternally to get the event back. For fixing this issue, we need to add the vupdate_no_lock interrupt in the interrupt list.

2021-02-22doc: use KCFLAGS instead of EXTRA_CFLAGS to pass flags from command lineMasahiro Yamada
You should use KCFLAGS to pass additional compiler flags from the command line. Using EXTRA_CFLAGS is wrong. EXTRA_CFLAGS is supposed to specify flags applied only to the current Makefile (and now deprecated in favor of ccflags-y). It is still used in arch/mips/kvm/Makefile (and possibly in external modules too). Passing EXTRA_CFLAGS from the command line overwrites it and breaks the build. I also fixed drivers/gpu/drm/tilcdc/Makefile because commit 816175dd1fd7 ("drivers/gpu/drm/tilcdc: Makefile, only -Werror when no -W* in EXTRA_CFLAGS") was based on the same misunderstanding.

2021-02-18drm/amdkfd: Fix recursive lock warningsFelix Kuehling
memalloc_nofs_save/restore are no longer sufficient to prevent recursive lock warnings when holding locks that can be taken in MMU notifiers. Use memalloc_noreclaim_save/restore instead.

2021-02-18drm/amd/display: Add FPU wrappers to dcn21_validate_bandwidth()Jan Kokemüller
dcn21_validate_bandwidth() calls functions that use floating point math. On my machine this sometimes results in simd exceptions when there are other FPU users such as KVM virtual machines running. The screen freezes completely in this case. Wrapping the function with DC_FP_START()/DC_FP_END() seems to solve the problem. This mirrors the approach used for dcn20_validate_bandwidth. Tested on a AMD Ryzen 7 PRO 4750U (Renoir).
