Hi Hsin-Yi, thanks for the comment, I'll change it in the next serial.
As video-interfaces.yaml not exist in drm-next, I'm waiting for 5.12-rc1 to

Hi Geert,
IMHO - QEMU is irrelevant here. since I can do passthrough --
in fact -- many drivers do use timeout in .fb_sync
e.g. i810fb_sync(), nouveau_fbcon_sync(), sm501fb_sync() etc..
I believe the correct behaviour should be a timeout wait instead of
waiting indefinitely.

Add a virtual hardware or vblank-less mode as a module to enable
VKMS to emulate virtual graphic drivers. This mode can be enabled
by setting enable_virtual_hw=1 at the time of loading VKMS.
A new function vkms_crtc_composer() has been added to bypass the

Hi Dave and Daniel,
here's this week's PR for drm-misc-fixes. One of the patches is a memory
leak; the rest is for hardware issues.

According to DP spec, broadcast message LCT equals to 1 and LCR equals

In addition, revise a bit the hdr->rad handling to include broadcast

Hey Adrien,
This looks good to me. All that is missing is DRM_BRIDGE_OP_HPD
support, when that's been implemented I think this series is ready to
be merged.

USB devices cannot perform DMA and hence have no dma_mask set in their
device structure. Therefore importing dmabuf into a USB-based driver
fails, which breaks joining and mirroring of display in X11.
For USB devices, pick the associated USB controller as attachment device.
This allows the DRM
