Subject: KMS cursor BO semantics
Date: Fri, 04 Nov 2011 12:59:59 +0100	[thread overview]
Message-ID: <4EB3D3BF.70909@vmware.com> (raw)

Hi.

I have a question about the semantics of the DRM_IOCTL_MODE_CURSOR iotcl:

Some hardware (vmware's virtual in particular) may not be able to pick 
up the changes from a bo directly, since the cursor data is sent though 
the command stream. Hence we need a notification when the cursor image 
has changed.

Could we *require* that a cursor image change needs to be followed by an 
ioctl call with the flag
DRM_MODE_CURSOR_BO?

Thanks,
Thomas
