Just in time for the holidays is a new Nouveau Companion newsletter
to update the community on the status of this open-source 2D/3D NVIDIA driver
that is written by clean room reverse-engineering of NVIDIA's binary driver. It
has been a while since Nouveau
Companion 40, but there is still active work going into this X.Org driver.
Among the topics covered in the 41st edition of the Nouveau Companion is kernel
on top of TTM
(similar to the
GEM-ified TTM Radeon driver), and thermal monitoring code for the Nouveau
Well, I bet most of you did not expect me to show up shortly before
the end of the year with yet another TiNDC. There has been some turmoil regarding
my job. At first it was too much work followed by a somewhat unexpected folding
of the company. So I had to find a new job, which is why I never turned up for
quite some time.
PQ jumped in and did a splendid job on TiNDC #40 which gave me
some headroom in digging through the pile of IRC logs. So this issue will mostly
touch older topics and tries to stay clear of what was already covered by PQ.
In the future I hope to write an issue at least once a month.
Much has happened: NVidia has announced new cards, released a
bunch of beta drivers and a new final release. GeForce 5 cards are now delegated
to the legacy driver.
As always: Corrections, additions and questions either on IRC
or on the Phoronix Forums will be welcome.
The (Not So) Current Status
Ok, much ground to cover. I will start to summarize events from
June 1st to October 30th. The next issue will cover everything from November 1st
up to the then current status.
Silverpower reported hard lockups from Nouveau. P0g investigated
and found that the DRM detected a different arch than what the DDX used. He posted
a patch which Silverpower tested, but which still caused lockups. P0g was a bit
confused because the DRM detected a different arch than what was used by the DDX.
Marcheu cleared up the confusion by giving an example: The DDX
may use NV10 EXA on NV20 while using the NV20 context switching code.
Mjg59 and Malc0 were working on suspend / resume on a laptop.
Mjg59 had problems in restoring the display to a working state. Some of the noticed
- 1x1 pixel display size detected
- backlight not turned on after a real suspend
Faking a suspend / resume via ''echo -n test >/sys/power/disk,
echo -n disk >/sys/power/state'' printed out seemingly correct values, though
here). One reason - it turned out - was an old Nouveau version, which still
had the old randr code as default.
