Hi!
I'm new to this list and I'm trying to get Mir running in a VMware
virtual machine on top of the vmwgfx driver stack.
The idea is to first get "mir_demo_server_basic" running with demo
clients and then move on to Xmir, patching up our drivers as
necessary.
Hi Thomas, thanks for looking into this. Feel free to also join
#ubuntu-mir on freenode if you need more direct information.
So far, I've encountered a couple of issues that might need
attention from MIR developers:
1) function mggh::DRMHelper::is_appropriate_device() in
gbm_display_helpers.c checks whether a drm device has any children
except itself. This is not true for vmwgfx, and the server will fail
to start thinking that our drm device is not appropriate. Why the
child requirement?
Will take a deeper look, probably an arbitrary requirement based
on what major hardware drivers expose.
This requirement is intended to be a rough-and-ready check for “does
this drm device have any output hardware”. The physical drm drivers all
expose their connectors as sub-objects of the main drm udev node.
OK. Need to check why they do that. Jakob, any idea?
We now also check to see whether any of the enumerated connectors are
actually connected, so the udev check should be able to go away.
Sounds great. IIRC there is an IOCTL to check whether kms is actually
supported, that might
come in handy.
Thanks,
Thomas
Chris
