Subject: [PATCH RESEND,v6 1/8] dt-bindings: gce: mt8195: Add CMDQ_SYNC_TOKEN_SECURE_THR_EOF event id
Date: Sun, 26 May 2024 22:44:36 +0800	[thread overview]
Message-ID: <20240526144443.14345-2-jason-jh.lin@mediatek.com> (raw)
In-Reply-To: <20240526144443.14345-1-jason-jh.lin@mediatek.com>

There are 2 kind of GCE event signal:
- The SW token means: a GCE event signal triggered by SW drivers.
e.g. SW driver append a GCE command to set a GCE event after a specific
GCE command. Or SW driver use CPU to write a event id to GCE register to
trigger the GCE event corresponding to that event id.

- The HW event means: a GCE event signal triggered by HW engines.
e.g. When HW OVL fetches all the data in frame buffer, HW OVL will send
a frame done irq and also send a frame done GCE event via HW bus directly.

CMDQ_SYNC_TOKEN_SECURE_THR_EOF is a SW token event that is set in the
end of each cmdq secure pkt. It is used as a secure irq to notify
CMDQ driver in the normal world that GCE secure thread has completed
a secure cmd buffer in thee secure world.
