VirtIO-GPU got a new config option for disabling KMS. There were two problems left unnoticed during review when the new option was added: 1. The IS_ENABLED(CONFIG_DRM_VIRTIO_GPU_KMS) check in the code was inverted, hence KMS was disabled when it should be enabled and vice versa. 2. The disabled KMS crashed kernel with a NULL dereference in drm_kms_helper_hotplug_event(), which shall not be invoked with a disabled KMS. Fix the inverted config option check in the code and skip handling the VIRTIO_GPU_EVENT_DISPLAY sent by host when KMS is disabled in guest to fix the crash. Acked-by:

Add a build option to disable modesetting support. This is useful in cases where the guest only needs to use the GPU in a headless mode, or (such as in the CrOS usage) window surfaces are proxied to a host compositor. As the modesetting ioctls are a big surface area for potential security bugs to be found (it's happened in the past, we should assume it will again in the future), it makes sense to have a build option to disable those ioctls in cases where they serve no legitimate purpose. v2: Use more if (IS_ENABLED(...)) v3: Also permit the host to advertise no scanouts v4: Spiff out commit msg v5: Make num_scanouts==0 and DRM_VIRTIO_GPU_KMS=n behave the same v6: Drop conditionally building virtgpu_display.c and early-out of it's init/fini fxns instead Signed-off-by:Rob Clark <robdclark@chromium.org> Reviewed-by:

Remove the bogus csync check and replace it with something that: - triggers for all forms of csync, not just the basic analog variant - actually populates the mode csync flags so that drivers can decide what to do with the mode Originally the code tried to outright reject csync, but that apparently broke some bogus LCD monitor that claimed to have a detailed mode that uses analog csync, despite also claiming the monitor only support separate sync: https://bugzilla.redhat.com/show_bug.cgi?id=540024 Potentially that monitor should just be quirked or something. Anyways, what we are dealing with now is some kind of funny i915 JSL machine with eDP where the panel claims to support a sensible 60Hz separate sync mode, and a 50Hz mode with bipolar analog csync. The 50Hz mode does not work so we want to not use it. Easiest way is to just correctly flag it as csync and the driver will reject it. TODO: or should we just reject any form of csync (or at least the analog variants) for digital display interfaces? v2: Grab digital csync polarity from hsync polarity bit (Jani) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/8146Reviewed-by:

The EDID of an HDR display defines EOTFs that are supported by the display and can be set in the HDR metadata infoframe. Userspace is expected to read the EDID and set an appropriate HDR_OUTPUT_METADATA. In drm_parse_hdr_metadata_block the kernel reads the supported EOTFs from the EDID and stores them in the drm_connector->hdr_sink_metadata. While doing so it also filters the EOTFs to the EOTFs the kernel knows about. When an HDR_OUTPUT_METADATA is set it then checks to make sure the EOTF is a supported EOTF. In cases where the kernel doesn't know about a new EOTF this check will fail, even if the EDID advertises support. Since it is expected that userspace reads the EDID to understand what the display supports it doesn't make sense for DRM to block an HDR_OUTPUT_METADATA if it contains an EOTF the kernel doesn't understand. This comes with the added benefit of future-proofing metadata support. If the spec defines a new EOTF there is no need to update DRM and an compositor can immediately make use of it. Bug: https://gitlab.freedesktop.org/wayland/weston/-/issues/609 v2: Distinguish EOTFs defind in kernel and ones defined in EDID in the commit description (Pekka) v3: Rebase; drm_hdmi_infoframe_set_hdr_metadata moved to drm_hdmi_helper.c Signed-off-by:

Currently we schedule a call to output_poll_execute from drm_kms_helper_poll_enable for 10s in future. Later we try to replace that in drm_helper_probe_single_connector_modes with a 0s schedule with delayed_event set. But as there is already a job in the queue this fails, and the immediate job we wanted with delayed_event set doesn't occur until 10s later. And that call acts as if connector state has changed, reprobing modes. This has a side effect of waking up a display that has been blanked. Make sure we cancel the old job before submitting the immediate one. Fixes: 162b6a57 ("drm/probe-helper: don't lose hotplug event") Acked-by:

The DisplayID structure version and primary use case are stored in the DisplayID Base Section. We should be checking them in a number of places when parsing the DisplayID blocks. Currently, we completely ignore the primary use case, and just look at the block tags without cross-checking against structure version. Store the version and primary use case in the DisplayID iterator, and provide accessors to them. In general, the information is needed when iterating the blocks, and this is a convenient place to both store and retrieve the information during parsing. Promote using accessors rather than users poking at the iterator directly. Cc: Iaroslav Boliukin <iam@lach.pw> Cc: Dmitry Osipenko <dmitry.osipenko@collabora.com> Signed-off-by:

The ttm BO now initially has NULL bo->resource, and leaves the driver the handle that. However it looks like we forgot to handle that for ttm_bo_move_memcpy() users, like with vram-gem, since it just silently returns zero. This seems to then trigger warnings like: WARNING: CPU: 0 PID: 1 at drivers/gpu/drm/drm_gem_vram_helper.c:255 drm_gem_vram_offset (??:?)

This should give the same behaviour as before. While we are here let's also treat calling ttm_bo_move_memcpy() with NULL bo->resource as programmer error, where expectation is that upper layers should now handle it.
