[PATCH 0/8] amd/display: Add GFX9+ modifier support.
by Bas Nieuwenhuizen 03 Sep '20

03 Sep '20

This adds modifier support to radeonsi. It has been tested on - VEGA10, RAVEN, NAVI14 - weston, sway, X with xf86-video-amdgpu (i.e. legacy path still works) and includes some basic testing of the layout code. The main goal is to keep it somewhat simple and regression free, so on the display side this series only exposes what the current GPU can render to. While we could expose more I think that is more suitable for follow-up work as the benefit would be minimal and there are some more … [View More]

[PATCH v4 00/78] drm/vc4: Support BCM2711 Display Pipeline
by Maxime Ripard 02 Sep '20

02 Sep '20

Hi everyone, Here's a (pretty long) series to introduce support in the VC4 DRM driver for the display pipeline found in the BCM2711 (and thus the RaspberryPi 4). The main differences are that there's two HDMI controllers and that there's more pixelvalve now. Those pixelvalve come with a mux in the HVS that still have only 3 FIFOs. Both of those differences are breaking a bunch of expectations in the driver, so we first need a good bunch of cleanup and reworks to introduce support for the new … [View More]controllers. Similarly, the HDMI controller has all its registers shuffled and split in multiple controllers now, so we need a bunch of changes to support this as well. Only the HDMI support is enabled for now (even though the DPI and DSI outputs have been tested too). Let me know if you have any comments Maxime Cc: bcm-kernel-feedback-list(a)broadcom.com Cc: devicetree(a)vger.kernel.org Cc: Kamal Dasu <kdasu.kdev(a)gmail.com> Cc: linux-clk(a)vger.kernel.org Cc:

[PATCH v6 0/7] Asynchronous flip implementation for i915
by Karthik B S 02 Sep '20

Without async flip support in the kernel, fullscreen apps where game resolution is equal to the screen resolution, must perform an extra blit per frame prior to flipping. Asynchronous page flips will also boost the FPS of Mesa benchmarks. v2: -Few patches have been squashed and patches have been shuffled as per the reviews on the previous version. v3: -Few patches have been squashed and patches have been shuffled as per the reviews on the previous version. v4: -Made changes to fix … [View More]

[re-send][PATCH] drm/via: reduce no need mutex_lock area
by Bernard 02 Sep '20

02 Sep '20

In function via_mem_alloc`s error branch, DRM_ERROR is protected in the mutex_lock(&dev->struct_mutex) area. From the code, we see that DRM_ERROR is just an error log print without any struct element, there is no need to protect this.

[PATCH] drm/vkms: add support for gamma_set interface
by Sidong Yang 02 Sep '20

Currently vkms module doesn't support gamma function for userspace. so igt subtests in kms_plane(pixel-format-pipe-A-plan) failed for calling drmModeCrtcSetGamma().
