Unfortunately this leads to double definitions of some symbols: [ 1.000000] Copyright (c) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, [ 1.000000] 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, [ 1.000000] 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 [ 1.000000] The NetBSD Foundation, Inc.

Still the same kind of linking errors.. example of double definition: /home/rhialto/NetBSD-10/usr/src/sys/arch/amd64/compile/GENERIC_NOKMS/../../../../external/bsd/drm2/drm/drm_agp_hook.c:140: multiple definition of `drm_agp_init'; drm_agpsupport.o:/home/rhialto/NetBSD-10/usr/src/sys/arch/amd64/compile/GENERIC_NOKMS/../../../../external/bsd/drm/dist/bsd-core/drm_agpsupport.c:404: first defined here It looks like drm_agp_hook.c should not be included, but how do I find out what pulls it in? Further removing "genfb*" seemed helpful, after grepping a lot through all files.* files, but that didn't do the trick. Example of undefined symbol: ld: i915_drv.o: in function `i915drm_detach': /home/rhialto/NetBSD-10/usr/src/sys/arch/amd64/compile/GENERIC_NOKMS/../../../../external/bsd/drm/dist/bsd-core/i915_drv.c:212: undefined reference to `drm_detach' I've been stripping down the kernel config more and more, but still the same problems remain. "config -ddddddd" isn't too helpful, in the end; it leaves out crucial information of "why is this thing included". It seems like most of the output isn't even related to the actually configured devices, but all of the possible ones, which makes it hard to find the relevant parts. > The interesting question being if the previous X11 "services" could be > restored on a 10.0 kernel by disabling drmkms and using the legacy drm > drivers... well, not having a kernel yet, I'm giving up for the evening. Maybe tomorrow I get some inspiration again. Oh by the way, Driver "wsfb" works fine, so far as I can see, but without accelleration, so unsuitable for VICE (which requires GL) or watching video (requires GL or XV). > Thierry Laronde <tlaronde +AT+ kergis +dot+ com> -Olaf. -- ___ Olaf 'Rhialto' Seibert <rhialto/at/falu.nl> \X/ There is no AI.
