Subject: [PATCH 2/6] drm/msm: Add new PM4 type7 opcodes
Date: Thu,  8 Mar 2018 11:36:21 +0530	[thread overview]
Message-ID: <1520489185-21828-3-git-send-email-smasetty@codeaurora.org> (raw)
In-Reply-To: <1520489185-21828-1-git-send-email-smasetty-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

This patch adds the following two opcodes:

CP_SET_MARKER opcode is a way to tell CP the current mode of GPU
operation(useful if preemption is in use).

CP_SET_PSEUDO_REG opcode will instruct CP to set a bunch of internal
CP registers, again useful for the preemption save/restore sequence.
