Subject: Re: [PATCH v2 21/23] drm/msm: Support KMS backends without a display IRQ
Date: Mon, 26 Oct 2026 14:40:14 +0000 [thread overview]
Message-ID: <sashiko-outbox-185408@kernel.org> (raw)
In-Reply-To: <20261026-jshekhar-dcp-hlos-v2-21-7cf014efdee1@oss.qualcomm.com>
> Some MSM KMS backends receive display events through firmware or
> another transport and therefore have no host-visible display interrupt.
> Rejecting such a backend during common KMS initialization prevents
> it from using the MSM DRM framework.
>
> Allow KMS backends to use IRQ_NOTCONNECTED. DCP receives VSYNC and
> frame-scan completion as asynchronous HFI events over VirtIO; its IPCC
> interrupt is reserved for power-notify acknowledgments. Existing
> IRQ-backed KMS implementations retain their current request and
> teardown flow.
