>Environment:


System: NetBSD 8.0_BETA, NetBSD-current
Architecture: amd64
Machine: amd64
>Description:

Attempts to boot NetBSD-8 or NetBSD-current installer images on any computer 
with a modern NVIDIA card results in a panic saying console isn't found. 
Pleasantly, the keyboard works at the db prompt.
Attempting to boot with -c to try to disable nouveau gives a console on which 
the keyboard doesn't work. After the "uc> ", there's a rapidly flashing text 
cursor. The system does not respond to keystrokes at all.
>How-To-Repeat:

Try to install on a system with a modern NVIDIA card. Try to use boot -c on a 
system with a modern NVIDIA card. Tested with GTX 1050, 1080, 1080Ti, but I'm 
sure it affects many others.
>Fix:

Replace video card, or make a custom kernel and/or custom installer.

 i think the simplest way to fix this for now would be to black list
 the newer nvidia cards that don't work -- the nvidia driver has a
 generic "made by nvidia, is VGA class" match routine, so it matches
 pretty much all nvidia pci-style GPus.  this _normally_ works ok as
 previously the newer cards worked "ok" if not well accelerated, but
 the newer ones fail at it...

 then vga would attach, and vesa graphics work, and on the high end
 nvidia cards, vesa is surprisingly fast and usable.

 can you post a dmesg to go along with it to see where it fails?
 my newer card (still recognised as something by nouveau) tries to
 attach, fails, and continues booting normally, so some code to handle
 things does exist.

 Apologies that I didn't have time to convert to text.

 unfortunately, this only shows info that is actually known from
 the fact you've reported the cnopen panic.  we need the full
 dmesg so we can see why vga or whatever didn't attach.

 Are you using efiboot? that I can reproduce.
 I'll try to do something about it.

   | can you or anyone else with a modern nvidia card test this patch?

 For me, with the typo fixed (or probably without, I did not try that) it
 correctly detects that my nvidea card is one of the unsupported ones,
 and does not attempt to configure it.

 Previously it had done ...

 (that's from a dmesg I saved before the timestamps were added).

Subject: PR/53258 CVS commit: src/sys/external/bsd/drm2/nouveau
Date: Mon, 21 May 2018 08:58:47 +0000

 Committed By:	mrg
 Date:		Mon May 21 08:58:47 UTC 2018

 Modified Files:
 	src/sys/external/bsd/drm2/nouveau: nouveau_pci.c

 Log Message:
 disable drm2 on modern nouveau cards (Pascal-based).

 our older drm doesn't have any support for modern Pascal or
 the second version of Maxwell (but not disabled here yet)
 but the driver tries to attach on any nvidia gpu.

 this should workaround PR#53258, and other issues reported
 with modern nvidia chipsets.

 the previous change doubled the check for pascal.  fix it so
 that we only check for later maxwell and pascal once each,
 as intended.

 It's time to close the ticket. All recent NetBSD installs with all sorts 
 of NVIDIA cards have worked. Thank you!
