Hey

On request of Noralf, I picked up the patches and prepared v5. Works fine with
Xorg, if configured according to:
     https://lists.freedesktop.org/archives/dri-devel/2014-January/052777.html
If anyone knows how to make Xorg pick it up dynamically without such a static
configuration, please let me know.



Hi

I am kind of curious as I do have interest in seeing this merged as well.

Please take a look at [1]. It's not the same driver, but something to the same effect. I know it's been almost a year, but I do work on this and intend to come back with a new version during 2021.

I currently work on fastboot support for the new driver. But it's a complicated matter and takes time. If there's interest, we could talk about merging what's already there.

Best regards
Thomas

There is an email in this thread from 2018, but when I tried to import an mbox
file from the whole month for August 2018, for some reason, kmail doesn't see
the sender and mailing list recipient in that one, so I will reply to this one,
because I was able to import this into my mail client.
https://www.spinics.net/lists/dri-devel/msg185519.html

I was able to get this to build against Linux 4.8, but not against a newer
version, some headers seem to have been split, and some things are off by 8
and other things. I could NOT find a git repo, but I was able to find the
newest patches I could find, and import those with git am against 4.8 with
some tweaks. If that is needed, I can link it, but only if you want.

However in QEMU I wasn't able to figure out how to make it create a
/dev/dri/card0 device, even after blacklisting the other modules for qxl,
cirrus, etc, and then modprobe-ing simpledrm

In my view something like this is would be useful. There still could be
hardware devices that don't have modesetting support (like vmvga in
qemu/virt-manager as an example). And most wayland servers need a
/dev/dri/card0 device as well as a potential user-mode TTY replacement would
also need /dev/dri/card0

I will admit I unfortunately failed to get it to build against master. I
couldn't figure out some of the changes, where some new structs were off by
a factor of 8.


Thanks
